Abstract. Objectives. The study aims to determine whether an arthroscopic ligament reconstruction is necessary to relieve clinical ankle instability symptoms in patients with an MRI scan showing medial or lateral ligament tear. Methods. This was a single centre retrospective case series study of 25 patients with ankle instability and ligament tear on MRI scan who had undergone arthroscopic procedures from January 2015 to December 2018. Patients were followed up for an average period of 3 years postoperatively to check for any recurrence of symptoms. Results. Of the 25 patients, 23 had ATFL tear on MRI scan, and 2 had deltoid ligament tear. Examination under anaesthesia was stable in 13 patients and unstable in 12 patients. The majority of the patients (76%) had a simple arthroscopic ankle debridement and no ligament repair. Six patients needed Brostrom repair. Conclusions. Our study has shown that in patients with MRI proven ligament tear and clinical instability, a ligament reconstruction was unnecessary in most patients. The instability symptoms of patients were relieved by simple ankle arthroscopic debridement

Abstract. Background. We know that tears of the Triangular fibrocartilage complex (TFCC) can cause DRUJ instability and ulnar sided wrist pain. This study shows the clinical result of patients who had arthroscopic transosseous repair of the TFCC tear with DRUJ instability. Arthroscopic repair of TFCC tear is a promising, minimally invasive surgical technique especially in patients with DRUJ instability. Materials and methods. Fifteen patients who underwent TFCC one tunnel repair form 2018–2021 were reviewed retrospectively in hospital. The proximal component of TFCC was repaired through arthroscopic one- tunnel transosseous suture technique. VAS score for pain, wrist range of motion, grip strength and post operative complications were evaluated and each patient was rated according to the DASH score. Results. The patients had a TFCC tear confirmed on MRI and was confirmed on arthroscopy by doing a hook test. The patients were followed up for 6 months. Twelve patients had normal stability of DRUJ and three patients showed mild laxity compared with the contralateral side. The mean VAS score reduced from 4.7 to 0.8 (P=0.001) and grip strength increased significantly. The quick DASH score (P=0.001)also showed significant functional improvement. No surgical related complications occurred. Conclusions. Arthroscopic one tunnel transosseous TFCC foveal repair can be an excellent and safe method for repair of TFCC tear with DRUJ instability. Its a good treatment option in terms of reliable pain relief, functional improvement and reestablishment of DRUJ stability

Background. Degeneration of the shoulder joint is a frequent problem. There are two main types of shoulder degeneration: Osteoarthritis and cuff tear arthropathy (CTA) which is characterized by a large rotator cuff tear and progressive articular damage. It is largely unknown why only some patients with large rotator cuff tears develop CTA. In this project, we investigated CT data from ‘healthy’ persons and patients with CTA with the help of 3D imaging technology and statistical shape models (SSM). We tried to define a native scapular anatomy that predesignate patients to develop CTA. Methods. Statistical shape modeling and reconstruction:. A collection of 110 CT images from patients without glenohumeral arthropathy or large cuff tears was segmented and meshed uniformly to construct a SSM. Point-to-point correspondence between the shapes in the dataset was obtained using non-rigid template registration. Principal component analysis was used to obtain the mean shape and shape variation of the scapula model. Bias towards the template shape was minimized by repeating the non-rigid template registration with the resulting mean shape of the first iteration. Eighty-six CT images from patients with different severities of CTA were analyzed by an experienced shoulder surgeon and classified. CT images were segmented and inspected for signs of glenoid erosion. Remaining healthy parts of the eroded scapulae were partitioned and used as input of the iterative reconstruction algorithm. During an iteration of this algorithm, 30 shape components of the shape model are optimized and the reconstructed shape is aligned with the healthy parts. The algorithm stops when convergence is reached. Measurements. Automatic 3D measurements were performed for both the healthy and reconstructed shapes, including glenoid version, inclination, offset and critical shoulder angle. These measurements were manually performed on the mean shape of the shape model by a surgeon, after which the point-to-point correspondence was used to transfer the measurements to each shape. Results. The critical shoulder angle was found to be significantly larger for the CTA scapulae compared to the references (P<0.01). When analyzing the classified scapulae significant differences were found for the version angle in the scapulae of group 4a/4b and the critical shoulder angle of group 3 when compared to the references (P<0.05). Conclusion. Patients with CTA have a larger critical shoulder angle compared with reference patients. Some significant differences are found between the scapulae from patients in different stages of CTA and healthy references, however the differences are smaller than the accuracy of the SSM reconstruction. Therefore, we are unable to conclude that there is a predisposing anatomy in terms of glenoid version, inclination or offset for CTA

Aim. The present study aimed to assess the accuracy of preoperative departmental ultrasound scans in identifying rotator cuff tears at our institution. Methods. Preoperative ultrasound scan reports were obtained from 64 consecutive patients who subsequently underwent arthroscopic subacromial decompression and/or rotator cuff repair. Data was collected retrospectively using our 2010 database. The ultrasound reports were compared with the arthroscopic findings. The presence or absence of partial and full thickness rotator cuff tears was recorded. Results. Ultrasound correctly identified 30/43 (70%) of all tears, 18/30 (60%) of full thickness tears but only 1/13 (8%) of partial tears seen at arthroscopy. Of the remaining 12 partial tears seen at surgery, 6 were misdiagnosed as full thickness tears on ultrasound and 6 were not picked up at all. Five partial thickness tears were repaired and the rest were debrided. If both full and partial thickness tears are counted as true positives, ultrasound had a sensitivity of 70%, a specificity of 67%, a positive predictive value of 81%, a negative predictive value of 51% and an overall accuracy of 69%. If only partial tears are counted as true positives sensitivity decreases to 8% and positive predictive value to 10%. Conclusion. In this series a preoperative departmental ultrasound scan identified 70% of the actual rotator cuff tears present at arthroscopy. However ultrasound was not accurate in identifying partial thickness tears or distinguishing them from full thickness defects. Due to this relatively low sensitivity, we question the usefulness of routine preoperative departmental ultrasound scans in the evaluation of suspected cuff tears

No animal model currently exists for hip abductor tendon tears. We aimed to 1. Develop a large animal model of delayed abductor tendon repair and 2. To compare the results of acute and delayed tendon repair using this model. Fourteen adult Romney ewes underwent detachment of gluteus medius tendon using diathermy. The detached tendons were protected using silicone tubing. Relook was performed at six and 16 weeks following detachment, histological analysis of the muscle and tendon were performed. We then attempted repair of the tendon in six animals in the six weeks group and compared the results to four acute repairs (tendon detachment and repair performed at the same time). At 12 weeks, all animals were culled and the tendon–bone block taken for histological and mechanical analysis. Histology grading using the modified Movin score confirmed similar tendon degenerative changes at both six and 16 weeks following detachment. Biomechanical testing demonstrated inferior mechanical properties in both the 6 and 16 weeks groups compared to healthy controls. At 12 weeks post repair, the acute repair group had a lower Movin's score (6.9 vs 9.4, p=0.064), and better muscle coverage (79.4% of normal vs 59.8%). On mechanical testing, the acute group had a significantly improved Young's Modulus compared to the delayed repair model (57.5MPa vs 39.4MPa, p=0.032). A six week delay between detachment and repair is sufficient to produce significant degenerative changes in the gluteus medius tendon. There are significant histological and mechanical differences in the acute and delayed repair groups at 12 weeks post op, suggesting that a delayed repair model should be used to study the clinical problem

The purpose of this study is to investigate the incidence of patients with isolated bundle ACL tear (either isolated posterolateral or anteromedial bundle) during arthroscopy, and its correlation with physical exam. The relevant surgical technique to reconstruct the ligament is discussed. Between September 2006 and March 2009, patients with ACL injuries who received double- bundle ACL reconstruction were reviewed retrospectively. A specialist fellow performed a physical exam before and after anaesthesia. Intraop status of the ACL tear was assessed with correlation of the physical findings. Patients with isolated bundle tear would receive anatomical reconstruction of the torn bundle with preservation of the intact bundle. Double-bundle hamstrings reconstruction would be performed to those with complete tear. Medical notes of 159 patients were reviewed. There were 118 patients (74%) with complete ACL tear, 36 (23%) with isolated AM tear, and 5 (3%) with PL tear. For patients with complete ACL tear, 94% and 100% had positive Lachman, 50% and 87% had positive pivot shift, before and after anaesthesia. For patients with isolated AM tear, 100% had positive Lachman, 36% and 19% had positive pivot shift, before and after anaesthesia. For patients with isolated PL tear, 100% had positive Lachman, 20% and 80% had positive pivot shift, before and after anaesthesia. With better understanding of ACL, patients with isolated-bundle tear can preserve their intact bundle during reconstruction. However, in this study we find that physical exam correlates poorly with the arthroscopic findings. Further imaging (e.g. MRI) may be helpful to differentiate patients from isolated- bundle tear to complete tear

Purpose. The purpose of this study was to evaluate the short to mid-term results after hemiarthroplasty with extended head prosthesis (CTA head) for patients with cuff tear arthopathy. Hypothesis. Favorable pain reduction would be obtained after hemiarthroplasty with the extended head design. Methods. From June 2005 to Apr 2012, 20 shoulders in 18 patients (mean age 75.6 years-old; 8 famales, 10 males) with cuff tear arthopathy (14, Seebauer 1A; 4, 1B; 1, IIA; 1, IIB) were treated with a hemiarthroplasty with an extended head design (14, CTA head, DePuy; 6, SMR, Lima, figure 1). Minimum follow up was 2 years. Patients were evaluated based on range of motion, the modified UCLA score, and complications. Data were analyzed by means of Wilcoxon signed-rank test. Results. There was no complication related to the implant during this study period (mean follow-up, 3.7 years). There was no infection, hardware loosening, or evidence of progressive acroimion wear. The UCLA score improved from 12.6 to 26.3 at final follow-up (p < 0.01), especially the pain score in the UCLA score improved from 2.8 to 7.6 (p < 0.01). Forward elevation increased slightly from 94° to 118° (p < 0.05), and, external rotation increased from 22.5° to 25.3°. No clinical improvement was observed in the Seebauer IIA patient. Overall, 85% of patients expressed an overall satisfaction with their surgery. Discussion and conclusion. Pain was significantly relieved in the majority of cases. The findings of this study indicate that favorable pain reduction could be obtained after hemiarthroplasty with the extended head design for patients with a cuff tear arthopathy without the superior humeral escape. A low complication rate could be expected for this procedure

Cementless surface replacement arthroplasty (CSRA) is an established treatment for glenohumeral osteoarthritis. Few studies however, evaluate its role in cuff tear arthopathy. The purpose of this study is to compare the outcomes of CSRA for both glenohumeral osteoarthritis and cuff tear arthopathy. 42 CSRA with the Mark IV Copeland prosthesis were performed for glenohumeral osteoarthritis (n=21) or cuff tear arthopathy (n=21). Patients were assessed with Oxford and Constant scores, patient satisfaction, range of motion and radiologically with plain radiographs. Mean follow-up and age was 5.2 years and 74 years in both groups. Functional outcomes were significantly higher in OA compared with CTA with OSS improving from 18 to 37.5 and 15 to 26 in both groups respectively. Forward flexion improved from 60° to 126° and 42° to 74° in both groups. Three patients in the CTA group had a deficient subscapularis tendon, two of whom dislocated anteriorly. Humeral head resurfacing arthroplasty is a viable treatment option for glenohumeral osteoarthritis. In patients with CTA, functional gains are limited. We suggest CSRA should be considered in low demand patients where pain is the primary problem. Caution should be taken in patients with a deficient subscapularis due to the high risk of dislocation

Most common current surgical treatment options for cuff tear arthropathy (CTA) are hemiarthroplasty and reverse total shoulder replacement. At our unit we have been using Reverse Total shoulder replacement (TSR) for CTA patients since 2001. We present our results of Reverse TSR in 64 patients (single surgeon) with a mean follow up of 2 years (Range 1 to 8 years). There were 45 males and 19 females in the study with a mean age of 70 years. Preoperative and postoperative Constant scores were collected by a team of specialist shoulder physiotherapists. Preoperatively plain radiographs were used to evaluate the severity of arthritis and bone stock availability. 90% patients showed an improvement in the Constant score post operatively. The mean improvement in Constant score was 25 points. The mean Pain Score (max 15) improved from 6.3 to 11.8; the mean ADL Score (max 20) improved from 6.8 to 12.3; the mean Range of Motion score (max 40) improved from 10.8 to 20.2; but the mean Power Score (max 25) only improved from 0.9 to 4.9. The differences in improvement were statistically significant in each category. A total 6 patients (10%) required 10 revision surgeries for various reasons. Two patients dislocated anteriorly who were treated by open reduction. Two patients required revision of the glenoid component due to loosening after a mean of 2 years. One patient required revision of the humeral component with strut grafting secondary to severe osteolysis. Only one patient required revision of both humeral and glenoid components secondary to malpositioning. Three patients died for reasons unconnected with their shoulder problems and surgery. Radiographic analysis at the latest follow up (mean 24 months) showed inferior glenoid notching in 40% cases. Heterotrophic ossification was not seen in our series. We conclude that reverse TSR is a viable option for treatment of cuff tear arthropathy however glenoid loosening and scapular notching remains an issue

Introduction. We reports the accuracy of direct Magnetic Resonance Arthrography (MRA) in detecting Triangular Fibrocartilage Complex (TFCC), Scapho-Lunate Ligament (SLL) and Luno-Triquetral Ligament (LTL) tears using wrist arthroscopy as the gold standard. Methods. We reviewed the records of all patients who underwent direct wrist MRA and subsequent arthroscopy over a 4-year period between June 2007 and March 2011. Demographic details, MRA findings, arthroscopy findings and the time interval between MRA and arthroscopy were recorded. The scans were performed using a 1.5T scanner and a high resolution wrist coil. All scans were reported by a musculoskeletal radiologist. Sensitivity, specificity, positive and negative predictive values (PPV & NPV) were calculated. Results. Two hundred and thirty four (234) MRA were performed over the study period. Fifty patients (50), who subsequently underwent 51 wrist arthroscopies (one bilateral), were included. The mean age was 35 years (range 16–64 years). The average delay between MRA and arthroscopy was 4.8 months (median 4 months, range 17 days–18 months). All patients were symptomatic with wrist pain. At arthroscopy, 26 TFCC tears, 7 SLL tears and 3 LTL tears were found. For TFCC, sensitivity was 96%, specificity 88%, PPV 89% and NPV 96%. For SLL, the values were 57%, 66%, 21% and 91% respectively. For LTL, 67%, 79%, 17% and 97%, respectively. Receiver Operating Characteristic (ROC) curve analysis showed that MRA only reliably differentiates between patients with and without TFCC tears (Area Under Curve AUC = 0.92, p < 0.0001) but not SLL (AUC = 0.62, p=0.28) or LTL (AUC = 0.73, p=0.17) tears. Conclusion. MRA is a sensitive and specific imaging modality for diagnosing TFCC tears. However, the diagnostic accuracy for SLL and LTL tears was not satisfactory. Wrist arthroscopy remains the gold standard if there is a clinical suspicion of inter-carpal ligament tears

Before reverse shoulder replacement was an option for rotator cuff tear arthropathy the treatment modalities were limited to injections and physical therapy for pain control, arthroscopic debridement with or without biceps tenodesis/tenotomy and hemiarthroplasty. Functional improvement was limited with these treatment options and success for pain control was moderate at best. The destructive nature of the rotator cuff deficient shoulder continued with medialization of the glenoid and erosion of the acromion seen even after replacement with hemiarthroplasty. The end result usually left the patient with a pseudo paralysis of the shoulder region functionally and uncontrolled pain that made later revision with a reverse implant difficult or impossible. Reverse arthroplasty was released for use in United States in 2004 for rotator cuff tear arthropathy. This initial procedure had a number of related complications that have been improved on over time with changes in implant design and better operative techniques. The long term results with reverse total shoulder arthroplasty have made this the procedure of choice for contained cuff tear arthropathy

The recognition of the role of TFCC as a major distal radioulnar joint stabilizer and a buffer to compressive forces indicates the importance of preserving as much of this structure as possible. We developed arthroscopic technique for repair of Palmer I B tears of TFCC using a hypodermic needle which obviates the need of any additional skin incision. With wrist under traction important landmarks like radial styloid process, ulnar styloid process, Lister's tubercle and extensor tendons are marked using skin marker. For placement of the arthroscope, 3–4 portal is used and for instruments 6 R and 6 U portals are used. An outside-in technique is used. A 19 G needle is inserted upward from 5mm proximal to the level of the 6 R portal through skin, subcutaneous tissue, capsular tissue and then through the 2mm inner side of detached area of TFCC, while stabilizing it with probe. A 2–0 polydioxanone-PDS suture is passed through needle and caught by grasper placed in the 6 R portal. Now needle is withdrawn and then suture is retrieved out of the joint through the 6 R portal. The procedure is repeated for required number of sutures for dorsal part of peripheral tear. Thus we have stitches with one limb exiting the joint through portal and the other limb entering the joint percutaneously. A small mosquito forceps is passed through the 6 R portal undermining subcutaneous area and these percutaneously passing limbs of sutures are withdrawn through the portal. Now we have sutures entering and exiting through the 6 R portal. Similar procedure is done for ulnar part of peripheral tear through the 6 U portal. Knots are tied and slid beneath the subcutaneous tissue. It offers advantages of a lower risk of neurovascular damage, reduced postoperative pain, faster rehabilitation and better cosmesis

Background. Cuff tear arthropathy represents a challenging problem to the shoulder arthoplasty surgeon. Poor results of conventional total shoulder arthroplasty in cuff deficient shoulders due to glenoid component loosening have meant hemiarthroplasty has been the traditional preferred option. Recently reverse total shoulder arthroplasty (RSA) has gained increasing popularity due to a clinical perception of an improved functional outcome. This is despite the lack of comparative data, particularly in relation to modern hemiarthroplasty prostheses. The aim of this study was to compare the early functional results of Hemiarthroplasty versus RSA in the management of cuff-tear arthropathy. Material and Methods. Patients were identified from the New Zealand National Joint Registry and matched for age, sex, and American Society of Anesthesiologists scores.102 primary hemiarthroplasties performed for cuff tear arthropathy were compared with 102 RSAs performed for the same diagnosis. Oxford shoulder scores (OSS) were collected prospectively at 6 months and five years post operatively together with mortality and revision rates. Results. There were 51 males and 51 females in each group, with a mean age of 71.6 in the Hemiarthroplasty group and 72.6 in the RSA group. The mean ASA score was 2.2 in both groups. The median OSS was 31.1 in the hemiarthroplasty group and 41.1 in the RSA group. This difference was maintained at five years. At follow up, there were 7 revisions in the hemiarthroplasty group and 5 in the RSA group. No difference in mortality was seen between the two groups. Conclusion. This study provides the first direct evidence of improved functional outcome of RSA compared to Hemiarthroplasty in patients with cuff tear arthropathy. Longer-term follow up is needed to confirm that the improved function is maintained and that complications such as component loosening remain comparable

We wished to assess the usefulness of Inspace balloon arthroplasty (IBA), in our Upper limb unit by regular patient reviews prospectively. This prospective study was started adhering to local approval process. Patients were identified in routine clinical practice by three upper limb consultants presenting with pain and disability and diagnosis of cuff tear was established clinically and on MRI. The patients were explained of ‘available’ treatment options and an information leaflet about balloon arthroplasty provided. Patients were seen in 4 weeks, in a dedicated clinic to find out their willingness to participate. Consultant shoulder surgeons carried out all Balloon arthroplasties and where the cuff was reparable or contraindications identified were excluded from study. All the patients were reviewed by an independent clinician pre-operatively and post operatively using the assessment tools of Oxford Shoulder Scores (OSS), SF12 and VAS at 6 weeks, followed by 3, 6, 12 months and annually after. We performed a total of 32 IBA procedures. At the latest follow-up we identified that 24 patients have completed 2 years post procedure. Of these patients 1 deceased after 6 months, 3 were lost to follow up one each at 6, 12 and 24 months. Three were revised to reverse TSA. The OSS reflects that the positive difference of 10 in the average scores (24 pre-operative versus 34 at 2 years) noted at one year follow up were maintained at 2 years. Similar observations made analysing at 12 months and 2 years scores for the VAS pain scores of 3 at 2 years compared to pre-operative score of 6 and so were improvements in both physical & mental components of SF12. Our study observes that the IBA provides a sustainable pain relief and functional improvements over 2 years and may be a suitable alternative in physiologically compromised patients with irreparable RCT

Background. Absence of rotator cuff allows unbalanced muscle forces of the shoulder to cause vertical migration of the humeral head. The translation of the humerus causes impaction of articular surface against the acromion. The purpose of the study is to assess outcome of Cuff tear arthropathy (CTA) Hemiarthroplasty prosthesis in this group of patients. Methods. Retrospective review was undertaken in 42 patients who underwent Global CTA Hemiarthroplasty between Jan 2001-Jan 2009. The mean length of follow up was 6 years. Results. The patients at review showed statistically significant improvement in Forward Flexion, Abduction and Numerical Pain Rating. There were four revision surgeries and the overall survival rate at ten years was 89 %. There was statistically significant improvement (p < 0.05) in forward flexion abduction and Numerical rating scale (p 0.02). Although improvement was noted in external and internal rotation this was not statistically significant. There was one perioperative humerus fracture which required plating at the same time of surgery. The fracture went on to heal uneventfully. There was also one post-operative haematoma which required arthroscopic washout. One patient underwent further arthroscopic debridement for poor ROM which improved from 20 Abd 20 FF to 90, 90 FF, Abd. There were four revision surgeries; 3 revisions to reverse geometry replacement; and one patient had removal of implant because of persistant dislocation of implant and patient did not want another major surgery. Patients who required revision had further erosion of acromion and poor ROM of < 20 Abd, FF, and Pain 8–10/10. Conclusion. This study shows that significant improvement in pain, and movements are achieved with this device. Acromial and glenoid erosion is a potential issue with this prosthesis and three revisions were required for this this problem. The results are better than standard hemiarthroplasty when used in this setting

The indication for rotator cuff repair in elderly patients is controversial. Methods. Consecutive patients over the age of 70 years, under the care of a single surgeon, receiving an arthroscopic rotator cuff repair were reviewed. Predominantly, a single row repair was performed using one (34 cases) or two (30) 5mm Fastin, double-loaded anchors. Double-row repair was performed in four cases. Subacromial decompression and treatment of biceps pathology were performed as necessary. Data were collected from medical records, digital radiology archives and during clinic appointments. Pain, motion, strength and function were quantified with the Constant-Murley Shoulder Outcome Score, administered pre operatively and at 1-year post operatively. Ultrasound scans were performed at one year to document integrity of the repair. Results. Sixty-nine arthroscopic cuff repairs were identified in 68 patients. The mean age was 77 years (70–86). The median ASA grade was 2 (79%). The dominant side was operated on in 68% of cases. A range of tear sizes were operated on (5 small, 17 moderate, 29 large and 18 massive). The tendons involved in the tear also varied (supraspinatus 12, supra and infraspinatus 53, supraspinatus and subscapularis 2, supraspinatus infraspinatus and subscapularis 2). Re-rupture occurred in 20 cases (29%). The mean Constant score increased from 23 (95% CI 19–26) to 59 (54–64) (P< 0.001). Where the repair remained sound, Constant score improved 42 points (95%CI 36–48). If the cuff re-ruptured, constant score also increased on average 12 points (95% CI 2–21). Re-rupture rate was highest for massive cuff repairs: ten out of eighteen (56%). Conclusion. Arthroscopic rotator cuff repair in the elderly is a successful procedure. Approximately seven out of ten repairs remained intact after one year. Even where re-rupture occurs, a significant improvement in the Constant score was found

Rotator cuff arthropathy is a challenging problem to treat in many patients whose function remains intact despite pain from arthritis. In recent years, the introduction of reverse shoulder arthroplasty has improved the function and pain in pseudoparalytic shoulders with rotator cuff deficiency. However, significant evidence exists to support the use of alternative surgical and non-surgical treatments for those patients who suffer from the pain of arthritis while maintaining an intact force-couple of the rotator cuff and relatively well preserved function.

Meniscal tears commonly co-occur with ACL tears, and many studies address their side, pattern, and distribution. Few studies assess the patient's short-term functional outcome concerning tear radial and circumferential distribution based on the Cooper et al. classification. Meniscal tears require primary adequate treatment to restore knee function. Our hypothesis is to preserve the meniscal rim as much as possible to maintain the load-bearing capacity of the menisci after meniscectomy. The purpose of this study is to document the location and type of meniscal tears that accompany anterior cruciate ligament (ACL) tears and their effect on patient functional outcomes following arthroscopic ACL reconstruction and meniscectomy. This prospective cross-sectional observational study was conducted at AL-BASRA Teaching Hospital in Iraq between July 2018 and January 2020 among patients with combined ipsilateral ACL injury and meniscal tears. A total of 28 active young male patients, aged 18 to 42 years, were included. All patients were subjected to our questionnaire, full history, systemic and regional examination, laboratory investigations, imaging studies, preoperative rehabilitation, and were followed by Lysholm score 6 months postoperatively. All 28 patients were males, with a mean age of 27 ± 0.14 years. The right knee was the most commonly affected in 20/28 patients (71.4%). The medial meniscus was most commonly injured in 11 patients, 7 patients had lateral meniscal tears, and 10 patients had tears in both menisci. The most common tear pattern of the medial meniscus was a bucket handle tear (36.4%), while longitudinal tears were the most frequent in the lateral meniscus (71.4%) (P-value = 0.04). The most common radial tear location was zone E-F (5/28, 17.8%), and the most common circumferential zone affected was the middle and inner third, reported in 50% of tears. Good and excellent outcomes using the Lysholm score after 6 months were obtained in 42.9% and 17.9% of patients, respectively. Better functional scores were associated with lateral meniscal tears, bucket handle tears, tears extending to a more peripheral vascular area, and if no more than one-third of the meniscus was resected (P-value = 0.002). Less favourable outcomes were reported in smokers, posterior horn tears, and when surgery was delayed more than 1 year (P-value = 0.03). We conclude that there is a negative correlation between the amount of meniscus resected and functional outcome. Delayed ACL reconstruction increases the risk of bimeniscal tears. Bucket handle tears are the most common tears, mostly in the medial meniscus, while longitudinal tears are most common in the lateral meniscus. We recommend performing early ACL reconstruction within 12 months to reduce the risk of bimeniscal injuries

A larger radial tuberosity, and therefore a smaller radioulnar space, may cause mechanical impingement of the DBT predisposing to tear. We sought to investigate anatomic factors associated with partial DBT tears by retrospectively reviewing 3-T MRI scans of elbows with partial DBT tears and a normal elbow comparison group. 3-T MRI scans of elbows with partial DBT tears and elbows with no known pathology were reviewed retrospectively by two independent observers. Basic demographic data were collected and measurements of radial tuberosity length, radial tuberosity thickness, radio-ulnar space, and radial tuberosity-ulnar space were made using simultaneous tracker lines and a standardised technique. The presence or absence of enthesophytes and the presence of a single or double DBT were noted. 26 3-T MRI scans of 26 elbows with partial DBT tears and 30 3-T MRI scans of 30 elbows without pathology were included. Basic demographic data was comparable between the two groups. The tear group showed statistically significant larger mean measurements for radial tuberosity length (24.3mm vs 21.3mm, p=0.002), and radial tuberosity thickness (5.5mm vs 3.7mm, p=<0.0001. The tear group also showed statistically significant smaller measurements for radio-ulnar space (8.2mm vs 10.0mm, p=0.010), and radial tuberosity-ulnar space (7.2mm vs 9.1mm, p=0.013). There was a statistically significant positive correlation between partial DBT tears and presence of enthesophytes (p=0.007) as well as between partial DBT tears and having two discrete DBTs rather than a single or interdigitating tendon (p=<0.0001). Larger radial tuberosities, and smaller radio-ulnar and radial tuberosity-ulnar spaces are associated with partial DBT tears. This may be due to chronic impingement, tendon delamination and consequent weakness which ultimately leads to tears. Enthesophytes may be associated with tears for the same reason. Having two discrete DBTs that do not interdigitate prior to insertion is also associated with partial tears

Hip abductor tears(AT) have long been under-recognized, under-reported and under-treated. There is a paucity of data on the prevalence, morphology and associated factors. Patients with “rotator cuff tears of the hip” that are recognized and repaired during total hip arthroplasty(THA) report comparable outcomes to patients with intact abductor tendons at THA. The study was a retrospective review of 997 primary THA done by a single surgeon from 2012–2022. Incidental findings of AT identified during the anterolateral approach to the hip were documented with patient name, gender, age and diagnosis. The extent and size of the tears of the Gluteus medius and Minimus were recorded. Xrays and MRI's were collected for the 140 patients who had AT and matched 1:1 with respect to age and gender against 140 patients that had documented good muscle quality and integrity. Radiographic measurements (Neck shaft angle, inter-teardrop distance, Pelvis width, trochanteric width and irregularities, bodyweight moment arm and abductor moment arm) were compared between the 2 groups in an effort to determine if any radiographic feature would predict AT. The prevalence of AT were 14%. Females had statistically more tears than males(18vs10%), while patients over the age of 70y had statistically more tears overall(19,7vs10,4%), but also more Gluteus Medius tears specifically(13,9vs5,3%). Radiographic measurements did not statistically differ between the tear and control group, except for the presence of trochanteric irregularities. MRI's showed that 50% of AT were missed and subsequently identified during surgery. Abductor tears are still underrecognized and undertreated during THA which can results in inferior outcomes. The surgeon should have an high index of suspicion in elderly females with trochanteric irregularities and although an MRI for every patient won't be feasible, one should always be prepared and equipped to repair the abductor tendons during THA
