We retrospectively analysed a single surgeon series of 22 TER in 21 patients over a 12 year period. The mean age and follow up was 59.1 years and 64 months respectively. DASH scores assessed pre and post op confirmed a significant improvement. Complications included infection, intra-operative fracture, peri-prosthetic fracture and aseptic loosening. 6 revisions were performed for various reasons.4 patients had died due to unrelated causes. The 10 year survival rate with symptomatic aseptic loosening as the end point was 93%. 5 patients had radiological loosening but were clinically asymptomatic. TER is a rewarding procedure in with advanced RA

TER is a viable surgical option in patients with advanced RA with painful stiff elbows. We retrospectively analysed 22 TER performed in 21 patients over a 12 year period by a single surgeon, with a mean follow up of 64 months (10–145). Disability of the arm, shoulder and hand (DASH) scores were performed pre-operatively and post-operatively in patients through postal questionnaires. The mean age was 59.1 years (32–78). There were 12 women and 9 men. The mean pre-operative DASH score was 72.3 (45.0–91.7) and post-operatively improved to 46.8 (21.7–94.2). Complications included infection, peri-operative fracture, peri-prosthetic fracture and aseptic loosening. There were 6 revisions performed, 2 for peri-prosthetic fracture, 2 for infection, 1 for intra-operative fracture and 1 for symptomatic aseptic loosening. Four patients had died due to unrelated causes. The 10 year survival rate with symptomatic aseptic loosening as the end point was 93% and revisions for all reasons was 69%. Follow up radiographs (in those without revision) were reviewed and 10 had satisfactory positioning of the prosthesis, 5 had loosening of the humeral or radial component and 1 had inadequate cement mantle but was clinically asymptomatic. TER is a rewarding procedure in with advanced RA. Our results are comparable to other published studies

Introduction. Extensor digitorum brevis (EDB) transfer is a useful method for treating chronic ankle instability in selected patients. It adds strength to the anterolateral capsule and provides proprioceptive feedback to functionally unstable ankles. Method. A single surgeon of case series of patients undergoing EDB transfer for chronic ankle instability following sporting injuries between January 2003 and July 2011 was reviewed. All patients underwent arthroscopic procedures in a day case setting. Outcomes were measured using return to sporting activity and the Karlsson functional scoring system. Results. 67 patients underwent unilateral EDB transfer over the 102 month period. 49 patients were male and all patients were aged less than 45. Minimum follow up was 6 months and all patients were discharged by 15 months (median follow up 9 months). Post operative assessment demonstrated normal range of ankle movements in all cases. At 6 months all patients had returned to sporting activity, achieving pre injury activity by 9 months. Karlsson scores were above 85.3 minor complications were seen - a superficial wound infection, limited paraesthesia of a branch of the superficial peroneal nerve and a case of complex regional pain syndrome which underwent full remission with early multimodal therapy. Conclusion. This study forms the largest published single surgeon series for EDB transfers. The data contributes to the body of evidence supporting EDB transfers as a safe and effective day case procedure for treatment of chronic ankle instability in selected patients

Introduction. We present a single surgeon series of 20 modified Dunn osteotomies without surgical dislocation of the femoral head for slipped upper femoral epiphysis (SUFE). Method. All patients from 2007 to 2011 who had a Dunn osteotomy for SUFE had their notes reviewed and we obtained an updated Non Arthritic Hip Score. Results. 20 patients were identified, of which 5 were female, with a combined average age of 14. The average duration of symptoms prior to the procedure was 10.2 weeks (range, 4–78). Classifications divided the cases into 7 chronic slips, 7 acute-on-chronic, and 5 acute., and 7 of the cases were unstable slips with an average slip angle of 71 degrees (range 65–85). All slips were grade 3. Average follow up was 26.2 months (range, 2–62). 3 developed avasular necrosis (2 unstable, 1 stable) and 2 patients had symptomatic leg length discrepancy. Preoperative MRI scans were performed in 4 patients and showed vascular compromise, but this did not always correlate with intraoperative findings of avascularity when the head was drilled. The average Nonarthritic hip score was 71.6 (range, 60–80). Summary. Dunn osteotomies are safe in patients with chronic slips, and have a low incidence of AVN. Overall function was good, even in those patients with segmental AVN scoring highly on their hip scores. Keeping the ligamentum teres intact and not dislocating the femoral head may improve vascularity of the head. Vascularity may also be assessed by preoperative MRI scans, although radiological suggestion of an avascular head which contradicted clinical findings and postoperative outcome may be due to transient vessel spasm

Clinical success of total knee arthroplasty is correlated with correct orientation of the components. Controversy remains in the orthopaedic community as to whether the intramedullary or extramedullary tibial alignment guide is more accurate in the tibial cut. Is there any difference between intramedullary and extramedullary jigs to achieve better accuracy of the tibial components in total knee replacements?. A retrospective study done on 100 patients during the time period 2007 to 2010. The 100 knee replacements were done by the same surgeon, where 50 patients had the intramedullary tibial alignment guide and the other 50 had the extramedullary one. The tibiofemoral angle was measured pre-operatively as well as post operatively, the tibial alignment angle was measured post operatively then the results were statistically analysed using the SPSS. There was no significant difference between both groups regarding the tibial alignment angles. Both techniques proved accurate in producing an acceptable post operative tibial component alignment angle. We recommend orthopaedic surgeons choose either technique knowing that accuracy levels are similar. The debate between intramedullary and extramedullary tibial cutting jigs/guides/ devices continues and most orthopaedic surgeons will use their preferred technique and will continue to achieve good post operative results as we have found in our centre. Our study is rare due to the fact we have a single surgeon performing both techniques, therefore controlling for any surgical experience or operating technique differences

Introduction

Total knee arthroplasty (TKA) has proven to be cost-effective and efficative in the treatment of osteoarthritic knees. Although traditional computer navigation systems improve implant placement, they require fixation of the femoral and tibial reference arrays for software recognition using anchoring pins. This increases the risk of bony fracture, pin sites infection and osteomyelitis. Our study aims to investigate the accuracy of a new inless navigation system (Brainlab VectorVision Knee 2.5 Navigation System) that would avoid these complications.

Introduction

Total ankle arthroplasty is increasingly used as an alternative to arthrodesis to treat advanced ankle arthritis. In an attempt to assess the survivorship and patient outcome as well as peri- and postoperative complications and possible risk factors, we retrospectively analyzed the demographics, clinical outcome and radiographic characteristics of 100 ankle prostheses (97 patients).

Introduction

Uncemented components necessitate accurate intraoperative assessment of size to avoid complications such as calcar fracture and subsidence whilst maintaining bone stock on the acetabular side. Potential problems can be anticipated pre-operatively with the use of a templating system. We proposed that pre-operative digital templating could accurately assess femoral and acetabular component size.

INTRODUCTION

The direct anterior approach to THR has become an increasingly popular minimally-invasive technique in an effort to minimize dislocation risk, facility early recovery, and diminish soft tissue injury. However, it has been associated with unique complications including intraoperative femur fracture, cutaneous nerve palsy, stem subsidence, and wound healing complications. These risk of these complications have been documented to be more likely in the surgeon's early experience with the approach. The minimally-invasive Supercapsular Percutaneous-Assisted (SuperPATH) technique was developed to minimize capsular and short-external rotator injury, minimize dislocation risk, and provide an easier transition from the standard posterior approach.

Aim

Over the last 15 years there has been a series of publications reporting the beneficial effects of elbow arthrolysis, with considerable variation in operative technique and post-operative management. Many advocate the use of passive stretching techniques in the early post-operative period if range of motion fails to improve satisfactorily. The purpose of this study was to assess our results of open elbow arthrolysis in patients who did not receive any passive stretching after discharge from hospital.

Introduction

The mobile-bearings were introduced in total knee arthroplasty (TKA) to improve the knee performance by simulating more closely ‘normal’ knee kinematics, and to increase the longevity of TKA by reducing the polyethylene wear and periprosthetic osteolysis. However, the superiority between posterior-stabilized mobile-bearing and fixed-bearing designs still remains controversial. The objective of the present study was to compare the mid-term results of Scorpio + Single Axis system (Stryker Howmedica Osteonics, Allendale, New Jersey) for the mobile-bearing knees and Duracon system (Stryker Howmedica Osteonics, Allendale, New Jersey) for the fixed bearing design with regard to clinical and roentgenographic outcome with special reference to any complications and survivorship.

In order to emulate normal knee kinematics more closely and thereby potentially improve wear characteristics and implant longevity the Medial Pivot type knee replacement geometry was designed. In the current study the clinical and radiographic results of 50 consecutive knee replacements using a Medial Pivot type knee replacement are reported; results are compared to the Australian Orthopaedic Associations National Joint Replacement Registry. The patients' data were crossed checked against the registry to see if they had been revised elsewhere. After a mean follow-up of 9.96 years results show that the Medial Pivot Knee replacement provides good pain relief and functional improvement according to KSS and Womac scores and on subjective patient questionnaires. There was one minor revision; insertion of a patella button at 6.64 years FU. There were no major revisions; all implants appeared to be well fixed on standard radiographic examination. While the revision rate for the Medial Pivot knee according to the Australia Joint Registry results is higher compared to all other types of knee replacements in the registry, and to what is reported in the literature on the medial pivot knee, it is not in the current series. Revision rate was similar to what is reported on in the literature, but after a longer follow-up period. However, long term follow-up is required to draw definitive conclusions on the longevity of this type of implant.

Objective

To assess the long term functional and objective outcomes for 2 stage Dupuytrens contracture correction.

Middle-aged female patients with painful hip arthritis often have high expectations, are physically active and are more likely to have underlying anatomical abnormalities such as DDH. Large hard bearing total hip replacement (THR) offer the possibilities of reduced wear and risk of dislocation.

The patients in this series all had surgery in the private sector and were operated on by one surgeon. They were selected for a hard bearing THR on the basis of age, health and expectations. Large bearing metal-on-metal (MOM) THR became possible in 2003, with ceramic-on-ceramic (COC) bearings used in patients with allergies to metal. There were 90 patients in the MOM group and 92 patients in the COC group. The mean age was 60 and the commonest diagnosis was osteoarthritis in both groups.

In the MOM group there were 8 complications: 2 deep infections, 1 death from PE, and 5 severe soft tissue reactions (pseudotumour). In the COC group there were 2 complications: 1 deep infection and 1 patient with intermittent squeaking.

The patients in this study were closely matched in terms of age and lifestyles. All of them were operated on by a single high volume specialist hip surgeon. The results suggest a high risk of failure in female patients who have had MOM THR. Most of the failures had described discomfort in the hip for many months before revision surgery. All of the failures were associated with a cemented CPT stem. The surgeon no longer uses MOM bearings in female patients because of the unacceptably high failure rate compared to COC bearings.

COC bearings appear to offer the active middle-aged female patient consistently good results and a low risk of failure at least in the short to medium term.

Introduction. Developmental dysplasia of the hip (DDH) can be managed through a variety of different surgical approaches from closed reduction to simple tenotomies of the adductors and through to osteotomies of the femur and pelvis. The rate of redislocation following open reduction for the treatment of DDH may be affected by the number of intraoperative surgeons. Materials and methods. We performed a retrospective cohort analysis of 109 patients who underwent open reduction with or without bony osteotomies as a primary intervention between 2013 and 2023. We measured the number of redislocations and number of operating surgeons (either 1 or 2 operating surgeons) to assess for any correlation. 109 patients were identified and corresponded to 121 primary hip operations, the mean age at operation was 82.2 months (range 6 to 739 months). During the 10-year period 7 hip redislocations were identified. Results. Of the 7 redislocated hips, the rate of redislocation was found to be higher in patients who had undergone surgery via a single surgeon (5 redislocations) compared to the dual surgeon cohort (2 redislocations), though this did not reach statistical significance. Redislocation was more common in female patients and right laterality 7.2% and 8.7% respectively, though this again did not reach statistical significance. Conclusions. We conclude that a single surgeon approach, female gender and right laterality are potential risk factors for redislocation following open reduction. Further investigation utilising a larger sample size would be required to appropriately explore these potential risk factors further

The significance of ring-fencing orthopaedic beds and protected elective sites have recently been highlighted by the British Orthopaedic Association & Royal College of Surgeons. During the pandemic many such elective setups were established with various degrees of success. This study aimed to compare the functioning and efficiency of a Orthopaedic Protected Elective Surgical Unit (PESU) instituted during the pandemic with the pre-pandemic elective service at our hospital (Pre-Pandemic ward or PPW). We retrospectively collected data of all patients who underwent elective Orthopaedic procedures in a protected elective unit during the pandemic (March 2020 – July 2020) and a similar cohort of patients operated via the routine elective service immediately prior to the pandemic (October 2019 – February 2020). Various parameters were compared and analysed. To minimise the effect of confounding factors a secondary analysis was undertaken comparing total hip replacements (THR) by a single surgeon via PESU (PESU-THR) and PPW (PPW-THR) over 5 months each from March-July 2021 and March-July 2019 respectively. A total of 192 cases were listed on PESU during the studied period whereas this number was 339 for PPW. However more than half (52%) of those listed for a surgery on PPW were cancelled and only 162 cases (48%) were actually performed. PESU had a significantly better conversion rate with only 12.5% being cancelled and 168 (87.5%) cases performed. 49% (87 out of 177) of the cases cancelled on PPW were due to a ‘bed unavailability’. A further 17% (30/177) and 16% (28/177) were cancelled due to ‘emergency case prioritisation’ and ‘patient deemed unfit’ respectively. In contrast only 3 out of the 24 patients cancelled on PESU were due to bed unavailability and the main reason for cancellation here was ‘patient deemed unfit’ (9/24). Single surgeon THR, showed similar demographic features for the 25 patients on PESU and 37 patients on PPW. The average age for these patients was 63 on PESU and 69 on PPW whereas the BMI was 33 and 30 respectively. The patients on PESU also demonstrated a decrease in length of hospital stay with an average of 3 days in comparison to 4.8 days for those admitted to PPW. PROMS scores were comparable at 6 weeks with an average improvement of 16.4/48 in the PESU-THR cohort and of 18.8/48 in the PPW-THR cohort. There were no readmissions or revisions recorded in the PESU-THR cohort while the PPW-THR cohort had 1 readmission and revision. Our study shows how a small ring fenced Orthopaedic elective unit in a district general hospital, even during a global pandemic, can function more efficiently than a routine elective facility with many shared services

The purpose of this study was to report all complications during the first consecutive 865 cases of bikini incision direct anterior approach (DAA) total hip arthroplasty (THA) performed by a single surgeon. The secondary aims of the study are to report our clinical outcomes and implant survivorship. We discuss our surgical technique to minimize complication rates during the procedure. We undertook a retrospective analysis of our complications, clinical outcomes and implant survivorship of 865 DAA THA's over a period of 6 years (mean = 5.1yrs from 2.9 to 9.4 years). The complication rates identified in this study were low. Medium term survival at minimum 2-year survival and revision as the end point, was 99.53% and 99.84% for the stem and acetabular components respectively. Womac score improved from 49 (range 40-58) preoperatively to 3.5(range 0-8.8) and similarly, HHS scores improved from 53(range 40-56) to 92.5(range 63-100) at final follow-up (mean = 5.1 yrs) when compared to preoperative scores. These results suggest that bikini incision DAA technique can be safely utilised to perform THA

Acromioclavicular joint injuries are one of the most common injuries in the shoulder girdle complex. Surgical management is considered based on patient profile, level of activity, pain, and classification of injury. To date, a vast array of surgical techniques have been proposed and described in the literature, a possible reason being that the optimal solution is still uncertain. The aim of this study is to determine the efficacy of an alternative surgical technique. This study is a retrospective case series of 80 patients that have been operated by a single surgeon over a period of 6 years. A novel surgical technique, the ‘BiPOD method’, was applied where a synthetic artificial ligament (LARS®) is used to reconstruct and reduce the acromioclavicular joint. The technique is done in a reproducible manner, where a single continuous artificial ligament is used to reduce and reconstruct both, the coracoclavicular and acromioclavicular ligament complexes to achieve bidirectional stability. Patients were followed-up postoperatively, either clinically where possible or telephonically. The Acromioclavicular Joint Instability Score (ACJI) and radiographic measurements were used to determine the clinical and surgical outcome of the surgery. Radiographic parameters, measuring the reduction of the coracoclavicular- and acromioclavicular joint, were analysed and documented. The results showed marked improvement in both, the coracoclavicular distance and acromioclavicular distance. Clinically, using the ACJI scoring system, the patients reported substantial improvement in pain and function. Complications were recorded but were insignificant. The BiPOD surgical technique, making use of an artificial LARS® ligament, has proven acceptable outcomes in the surgical management of acromioclavicular joint dislocations

Direct anterior approach (DAA) arthroplasty has generated great interest because of its minimally invasive and muscle sparing nature. Obese patients are reported to be associated with greater incidence of complications in primary joint replacement. The purpose of this study was to compare patient outcomes and complication rates between obese and non-obese patients undergoing primary total hip arthroplasty (THA) through a Bikini direct anterior incision. This retrospective, single surgeon study compared the outcome of 258 obese patients and 200 non-obese patients undergoing DAA THA using a Bikini incision, over a 7-year period. The average follow-up was 4.2 years (range 2.6-7.6 years). There were no statistically significant differences in the complication rate between the two groups. The obese group recorded 2 major (venous thromboembolism and peri-prosthetic fracture) and 2 minor complications (superficial wound infection), compared with the non-obese group, which recorded 2 major (deep-wound infection and peri-prosthetic fracture) and 1 minor complication (superficial wound infection). Patient-reported outcomes (WOMAC and Harris Hip Scores) showed significant post-operative improvements (p < 0.001) and did not differ between the two groups. Bikini DDA THA does not increase the complication rate in obese patients and offers similar clinical improvements compared to non-obese patients. (200 words)

Introduction. Anterior cruciate ligament (ACL) injuries represent a significant burden of disease to the orthopaedic surgeon and often necessitate surgical reconstruction in the presence of instability. The hamstring graft has traditionally been used to reconstruct the ACL but the quadriceps tendon (QT) graft has gained popularity due to its relatively low donor site morbidity. Methods. This is a single centre comparative retrospective analysis of prospectively collected data of patients who had an ACL reconstruction (either with single tendon quadrupled hamstring graft or soft tissue quadriceps tendon graft). All surgeries were performed by a single surgeon using the All-inside technique. For this study, there were 20 patients in each group. All patients received the same post-operative rehabilitation protocol and were added to the National Ligament Registry to monitor their patient related outcome scores (PROM). Results. The average age of patients in the QT group was 29 years (16 males, 4 females) and in the hamstring group was 28 years (18 males, 2 females). The most common mechanism of injury in both groups was a contact twisting injury. There were no statistical differences between the two patient groups in regards to PROMS and need for further revision surgery as analysed on the National Ligament Registry. Conclusions. The all soft tissue QT graft seems to be equivocal to quadrupled hamstring graft in terms of patient function and recovery graft characteristics. Further research may be needed to elucidate the long-term results of the all soft tissue QT graft given its recent increase in use
