Patient reported outcomes and satisfaction scores following excision of interdigital Morton's neuroma have been recently established. However, little is known regarding what patient factors affect these outcomes. This is the first and largest prospective study to determine which patient factors influence surgical outcome following Morton's neuroma excision. Over a seven-year period, 99 consecutive patients (112 feet) undergoing surgical excision of Morton's neuroma were prospectively studied. 78 patients were female with a mean age at operation of 56 years. Patient recorded outcomes and satisfaction were measured using the Manchester-Oxford Foot Questionnaire (MOXFQ), Short Form-12 (SF12) and a supplementary patient satisfaction survey three months pre and six months post-operatively. Patient demographics were recorded in addition to co-morbidities, deprivation, associated neuroma excision and other forefoot surgery. Obesity, deprivation and revision surgery proved to statistically worsen MOXFQ outcomes post-operatively (p=0.005, p=0.002 and p=0.004 respectively). Deprivation significantly worsened the mental component of the SF12 (p=0.043) and depression the physical component (p=0.026). No difference in outcome was identified for age, sex, time from diagnosis to surgery, multiple neuroma excision and other forefoot surgeries. 23.5percnt; of deprived patients were dissatisfied with their surgery compared to 7percnt; of the remaining cohort. Patient reported outcomes following resection of symptomatic Morton's neuroma are shown to be less favourable in those patients who display characteristics of obesity, depression, deprivation and in those who undertake revision neuroma resection. Surgery can be safely delayed, as time to surgery from diagnosis bears no impact on clinical outcome

Background. Femoroacetabular impingement (FAI) may be a predisposing factor in progression of osteoarthritis. The use of hip arthroscopy is in its infancy with very few studies currently reported. Early reports show favourable results for treatment of young patients with FAI. This prospective study over a larger age spectrum represents a significant addition to this expanding field of minimally invasive surgery. Methods. Over a twenty-two month period all patients undergoing interventional hip arthroscopy were recorded on a prospective database. Patient demographics, diagnosis, operative intervention and complications were noted. Patients were scored pre-operatively and postoperatively at 6 months and 1 year using the McCarthy score. Results. 94 patients met the criteria for inclusion in this study. Median age was 39 (15–66) years with 57.4% female, 16 patients were over the age of 50 years. At operation, 50 patients had a labral tear, 70 had cam impingement and 62 had chondral damage, with 21 of these deemed severe (grade 3 or 4). For all patients a mean increase in the McCarthy score of 14.6 (p=<0.0001) was seen at 6 months and 19.1 (p=0.0002) at 1 year postoperatively. For those over 50 years, at 6 months an increase of 11.9 (p=0.08) was seen, improving to 33.8 (p=<0.0001) at 1 year. Eight patients underwent THR, of these, 2 were over 50 years of age. All of this group of patients had chondral damage (50% judged as severe at arthroscopy). At 6 months postoperatively these patients had severe pain and their mean score worsened by −16.3 (p=0.2). Few complications were seen, 7 patients had tight access (5 males), 3 of which received chondral scuffing and 1 had the procedure abandoned, 1 patient had groin labral bruising and 2 patients had transient parasthesia. Conclusions. Patients see a gradual and significant improvement post hip arthroscopy, with symptoms continuing to improve until 1 year. This is a well-tolerated procedure with a low complication rate and the opportunity for treatment of a range of hip pathology. Patients over the age of 50 gain a significant improvement from this procedure. Two groups of patients who gain no improvement are those with inflammatory arthropathy and those with dysplastic acetabulae

Current knowledge regarding outcomes following surgical treatment of Morton's neuroma remains incomplete. This is the first prospective study to report the pre- and post-operative patient reported outcomes and satisfaction scores following excision of interdigital Morton's neuroma. Over a seven year period, 99 consecutive patients (112 feet) undergoing surgical excision of Morton's neuroma were prospectively studied. 78 patients were female with a mean age at operation of 56 years. Patient recorded outcomes and satisfaction were measured using the Manchester-Oxford Foot Questionnaire (MOXFQ), Short Form-12 (SF12) and a supplementary patient satisfaction survey three months pre and six months post-operatively. Statistically significant differences were found between the mean pre- and post-operative MOXFQ and physical component of the SF-12 (p<0.05). No difference in outcome was identified in patients in whom multiple neuromas were operated compared to single site surgery. However, revision surgery proved to statistically worsen MOXFQ outcomes post-operatively p<0.004. Overall satisfaction was reported as excellent (49%) or good (29%) by the majority of patients but 10% were dissatisfied with poor (8%) or very poor (2%) results expressed. Only 64% were pain free at the time of follow-up and 8% of patients MOXFQ scores worsened. These findings illustrate that overall, patient reported outcomes following resection of symptomatic Morton's neuroma are acceptable but may not be as favourable as earlier studies suggest. Caution should be taken when considering revision surgery which has shown to be a poor prognostic indicator. Contrary to current knowledge, multiple site surgery can be safely undertaken

Purpose. To evaluate the long term results of the use of a postoperative autologous blood reinfusion system in total knee arthroplasty. Material and method. In a prospective study, 176 patients who underwent unilateral total knee replacement, during the period 2004–2008, were evaluated (study group or group A). In all these patients a reinfusion system of unwashed blood salvaged was applied, while supplementary homologous blood transfusion was performed when required. The admission of banked blood transfusion determined by haemoglobin value (<9mg/dL) and/or clinical signs (blood pressure, pulses, etc). The value of haemoglobin, haematocrite and platelets recorded preoperatively and the 1st, 5th and 15th day after operation. Results were compared with the material of our previous prospective randomized controlled study (control groups B and C), where in 60 patients, between the years 2002–2004, the effectiveness of postoperative autologous blood reinfusion had been proved. Results. 19 patients of group A required postoperatively 23 units of homologous blood (total study group requirements23 blood units or 0.13 units per patient) while in group B required 1.5 units/patient and in group C 0.3 units/patient. In the study group the total homologous blood requirements reduced by 91% compared with group B (patients without autotransfusion system applied) and by 47% compared with group C (patients with autotransfusion system applied). There was no statistically significant difference in the postoperative values of Hb and Ht between the groups. None of the patients developed any adverse reactions after reinfusion. The cost of blood management was reduced in study group by 76%. Conclusions. The use of an autotransfusion system postoperatively minimizes practically the demands for homologous banked blood transfusion in total knee arthroplasty

Introduction. Distal radius fractures (DRF) are a common injury in the A&E departments, being a major cause of disability of the upper extremity. The aim of this prospective study is to assess the possible association between objective physical variables such as wrist range of movement (ROM), radiological parameters, and upper extremity disability (measured by the DASH questionnaire), after conservative treatment of DRF. Patients and methods. 44 patients with non-operatively managed DRF were enrolled in a prospective cohort study from July 2007 till September 2009. Inclusion criteria: unilateral DRF in skeletally mature patients, treated non-operatively with closed reduction and cast. Patients who sustained a previous fracture of the wrist, or bilateral wrist fracture, or with dementia, were excluded. After the closed reduction and inmovilization of the fracture in the A&E department we asked the patients to complete the DASH questionnaire, referring to their baseline pre-fracture state. All fractures were classified according to the AO classification. After one year, 36 patients were still available for follow-up purposes. We assesed the following objective physical variables: ROM of both wrists: flexion/extension arc and pronation/supination arch. We recorded the following radiologic parameters: radial angulation, volar angulation and radial shortening. The patient-perceived results were measured by the DASH questionnaire, while pain was measured using the VAS scale. Statistical analysis was performed using the SPSS 15.0. Results. Average follow up: 13,39 months (range 12.3–16.43). Mean age: 62.5 years (18–91). 75% of the fractures were 23A and 24,1% 23B. Average pre-fracture DASH score was 19.6 and 42.1 at the end of follow-up. Radial tilt: 18.18°. Volar tilt: 3,35°. Radial shortening: 5,76mm. ROM for flexion/extension of the involved wrist: 103.6° and non-involved wrist: 131.2°. ROM for pronation/supination involved wrist: 145.7° and non-involved wrist: 173.8°. Post-fracture VAS score: 3.5. We didn't find any significant statistical correlation between the lost of ROM, neither with radiological malaligment nor with patient-perceived outcomes. But we found a significant association between items 24–28 of the DASH (except item 26) questionnaire and the VAS score. Conclusions. The results of the present study show that, conservative treatment of DRF seems to deteriorate the patient self-reported outcomes measured by the DASH questionnaire

Background. Computer-assisted navigation systems for total knee arthroplasty (TKA) were introduced to improve implantation accuracy and to optimize ligament balancing. Several comparative studies in the literature confirmed an effect on the component position and other studies could not confirm these results. For ligament balancing most studies found no significant influence on the clinical outcome using a navigation system for TKA. In the literature there were no reports of mid-term results after navigated TKA. With our study we wanted to show if the use of a navigation system for TKA will have an influence on the component's position and on the clinical results at 5-year follow up. Methods. We enrolled 200 patients in a prospective randomized study with a minimum follow up of 5 years. 100 TKA were operated on without using a navigation system (Group A) and 100 surgeries (Group B) were done with computer assistance. Radiological investigation by standard radiographs including a long-leg X-ray was performed with a follow up rate in Group A of 86.2% versus 80.2% in Group B. We measured the mechanical axis of the leg, lateral distal femoral angel (LDFA), medial proximal tibial angle (MPTA), tibial slope and the alpha-angle of the patella. Clinical investigation was performed with a follow up rate in Group A of 85.7% versus 79.8% in Group B including the parameters for the range of motion (ROM), ligament balancing, anterior drawer test, feeling of instability, anterior knee pain, effusion, WOMAC Score, Insall Score and HSS Knee Score. Results. In both groups there was no aseptic loosening or difference in TKA survival rate (Group A 95.4% versus Group B 98.85% 5-year survival rate, p = 0.368). With the navigation technique the mechanical axis of the limb in the frontal plane was improved (p = 0.015; Group B: 1.67 ° ± 1.6° versus 2,44 ° ± 2.2 ° in Group A). 90% of the Group B and 81% of the Group A were within 3 ° varus/valgus deformity of the mechanical axis of the limb (p = 0.157). The accuracy of tibial slope was higher in the Group B (p = 0.001). More patients of the Group B (95% versus 79%) were within a deviation of 3 °, −7 ° tibial slope (p = 0.007). The mean deviation of 90 ° LDFA was higher (p = 0.034) in the Group A (1.89 ° versus 1.36 ° in Group B). Mean deviation of 90 ° MPTA, mean MPTA, mean LDFA and patella alpha angle were similar in both groups (p 0.253). There was no difference in ROM, ligament balancing, anterior drawer test, anterior knee pain or feeling of instability (p 0.058). Insall Knee Score total (181 Group A/191 Group B) and HSS Knee Score total (91 Group A/93 Group B) was higher with the navigated procedure in Group B (p 0.026). WOMAC total and HSS grades were similar in both groups (p 0.070). Conclusions. The accuracy of the mechanical axis of the limb and the tibial slope was higher with the navigated procedure. TKA survival rate and clinical outcomes were similar in both groups at 5-year follow up

This prospective study explores the outcomes of the Forth Valley Protocol (FVP) for the management of acute Achilles tendon ruptures. The protocol uses ultrasound as the primary mechanism to guide treatment. All patients presenting with acute tendoachilles rupture over a three-year period were included. Patients under 18 years of age, chronic ruptures, or prior surgery to the Achilles tendon were excluded. Patients with a gap ≤2cm had conservative management following an Early Rehabilitation Protocol (ERP) and >2cm underwent surgery (if an appropriate surgical candidate). Achilles Tendon Rupture Scores (ATRS) were obtained retrospectively. Fischer's exact test was used to determine statistical significance. 158 patients were included with a mean age of 53 (range 20–89). Ultrasound scans were obtained for 121 patients (76.5%), demonstrating a mean tendon gap of 1.61cm. 143 patients managed conservatively and 15 surgically. The overall re-rupture rate was 3.8% (n=6). All the re-ruptures occurred in patients treated conservatively, but this was not found to be statistically significant (n=6, P=1.0). The overall complication rate (excluding re-ruptures) was 1.9%. ATRS was comparable between both treatment modalities (P=0.382, 0.422), with a mean score of 86.6 in the conservative group and 81.4 in the surgical group. The FVP demonstrates low re-rupture and complication rates in line with other published studies. Patients with gaps ≤2.0cm on the ultrasound can be successfully treated conservatively with an ERP. This has potential benefits in terms improved patient outcomes, satisfaction, and preservation of resources

Background

A pedobarograph is a device that records pressures exerted by the foot on contact with the ground. Clinically most publications using pedobarography investigated diabetic foot pressures for prevention of ulcers, and assessing gait and sway. Only limited work was done on the effects of foot surgery on foot pressures. Any comparison between papers is hampered by the absence of available defined normal ranges of foot pressures.

Introduction

Neonatal fractures are often quite distressing to parents and medical teams involved. Their management can be daunting due to the small size of the patient, the concern of the new parents and the fear of the obstetric staff about litigation and deformity or long term disability of the neonate.

Introduction. Nerve conduction studies are considered to be the investigation of choice for the diagnosis of Carpal Tunnel Syndrome. However they are expensive and can be painful. We scored patients based on a ten point scoring system; four symptoms (Katz Hand Diagram – Classic and Probable pattern for tingling and numbness, nocturnal paresthesia, bilateral symptoms), four signs (weak thumb abduction test, Tinel sign, Phalen sign, Hypoalgesia in median nerve territory) and two risk factors (age more than 40 years and female sex). This was done in an effort to predict the severity of carpal tunnel syndrome and to correlate it with nerve conduction studies. Method. A prospective study of 59 patients was performed between May 2009 and March 2010. For every patient in the study we completed a scoring system based on ten points and correlated it with the severity (normal, mild, moderate and severe) result from the nerve conduction studies. Results. There were 61 completed data sets (59 patients, two patients had bilateral carpal tunnel release). The mean age of patients was 60 years (range: 37–91 years). The mean duration of symptoms was 17 months. The female to male ratio was 2.3:1. All scores greater than seven matched with nerve conduction study of moderate to severe intensity apart from three scores which were greater than seven that matched with a normal result. Conclusion. Based on this study, we believe that patients who score less than eight may require nerve conduction studies to confirm the diagnosis of carpal tunnel syndrome. However patients who score more than seven have a 93% chance of having moderate to severe carpal tunnel syndrome on nerve conduction studies

There is conflicting data from small retrospective studies as to whether pre-operative mental health influences the outcome of total knee replacement (TKR).

We assessed the effect of mental disability upon the outcome of TKR and whether mental health improves post-operatively. During a three year period patients undergoing TKR for primary osteoarthritis at the study centre had prospectively outcome data recorded (n=962). Pre-operative and one year short-form (SF) 12 scores and Oxford knee scores (OKS) were obtained. The mental component of the SF-12 was stratified into four groups according to level of mental disability (none ≥50, mild 40to49, moderate 30to39, severe <30). Ethical approval was obtained (11/AL/0079).

Patients with any degree of mental disability had a significantly greater subjective physical disability according to the SF-12 (p=0.06) and OKS (p<0.001). Although the improvement in the disease specific score (OKS) was not affected by a patients mental health (p=0.33). In contrast the improvement of the global physical health (SF-12) for patients with a mental disability did not improve to the same magnitude (p<0.001). However, patients with mental disability, of any degree, had a significant improvement in their mental health post-operatively (p<0.0001). Despite the similar improvement in the disease specific scores and improvement in their mental health, patients with mental disability were significantly more likely to be dissatisfied with their TKR at one year (p=0.001).

TKR for patients with poor mental health benefit from improvement in their mental health and in their knee function, but do have a higher rate of dissatisfaction.

Objectives

For a long time lateral release (LR) was performed as a standard procedure both, for patellofemoral pain syndrome (PFPS) and patellofemoral instability (PFI). However, recent biomechanical studies have shown that LR is not useful for decreasing the lateral force onto the patella, but is increasing not only medial but also lateral PFI. Furthermore, pain on palpation over the lateral patellofemoral joint space can result in patients treated with extensive LR. We postulate that in case of persistent PFI or PFPS after failed LR the reconstruction of the lateral retinaculum as an addition of the reconstruction of the medial patellofemoral ligament (MPFL) is necessary in terms of decreasing medial PFI as well as lateral pain.

Both conservative and operative forms of treatment have been recommended for patients with a ‘floating shoulder’. We compared the results of conservative and operative treatment in 25 patients with this injury and investigated the use of the glenopolar angle (GPA) as an indicator of the functional outcome. A total of 13 patients (ten male and three female; mean age 32.5 years (24.7 to 40.4)) were treated conservatively and 12 patients (ten male and two female; mean age 33.67 years (24.6 to 42.7)) were treated operatively by fixation of the clavicular fracture alone. Outcome was assessed using the Herscovici score, which was also related to changes in the GPA at one year post-operatively.

The mean Herscovici score was significantly better three months and two years after the injury in the operative group (p < 0.001 and p = 0.003, respectively). There was a negative correlation between the change in GPA and the Herscovici score at two years follow-up in both the conservative and operative groups, but neither were statistically significant (r = -0.295 and r = -0.19, respectively). There was a significant difference between the pre- and post-operative GPA in the operative group (p = 0.017).

When compared with conservative treatment, fixation of the clavicle alone gives better results in the treatment of patients with a floating shoulder. The GPA changes significantly with fixation of clavicle alone but there is no significant correlation between the pre-injury GPA and the final clinical outcome in these patients.

Introduction. treatment of femoral neck fractures in the physically active elderly, is still an open question. The comparison of total replacement and partial hip replacement showed substantial superiority of the first approach than the latter. We can not disregard the problems that THR can lead in the elderly: more surgical time, greater blood loss, major sacrifice of bone in osteoporotic subjects. The Tribofit® acetabular system, has the objective to overcome these problems with the implantation of a single 3mm soft, pliable buffer made of polycarbonate-urethane between the large diameter metal femoral head and the subchondral bone, thus replacing the articular cartilage. The surgical technique includes the reaming of the cartilage layer, the creation of a circumferential groove and the snap-fit insertion of the buffer. The purpose of the prospective study was to evaluate the effectiveness of this approach in the treatment of femoral neck fractures in the elderly. Materials and Methods. from September 2008 to July 2010 we performed 45 implants with the Tribofit® Acetabular Buffer (Active Implants®, Memphis TN, USA). The inclusion criteria for the study were: femoral neck fracture patients over 75 years of age, physically independent before the injury, with good life expectancy, mild or absent arthritis, absence of morphological alterations of the acetabulum. The average age of these patients was 81,2 (75–89), the sex distribution was 36 females and 9 males, with 22 fractures of the left hip and 23 of the right. In all cases an uncemented straight femoral stem was implanted. We recorded per-operative blood loss and intra-per-operative problems encountered. Follow-up were performed at 1, 3, 6 and 12 months post-op with radiographic control and clinical examination. The clinical outcome was objectively measured by the Harris Hip Score, pain Visual Analogue Scale and SF-36 questionnaire. Results. Of the 45 patients, 4 died of unrelated causes and 3 were lost to follow-up (2 due to cognitive impairment and 1 due to peri-prosthetic fracture of the femur). Of the 38 available for follow-up, all were followed at the staged time. No intra-operative problems were registered. The mean HHS for these fractures patients was 74,2 at 6 months and 86 at 12 months (90–80 good; 80–70 fair). The mean pain VAS was 4,3 at 6 months and 2 at 12 months. The mean SF-36 Score was 52,3 at 6 months and 53,2 at 12 months. Of the 38 followed, we had 2 dislocations in the third week post-op while the two patients were in a rehabilitation centre. Open reduction was carried out and in both cases the buffer was not dislodged. Discussion and conclusions. we believe the results with this new type of prosthesis are encouraging and comparable to if not better than other prosthetic options in the literature for this difficult-to-treat patient population

Introduction. The purpose of this study was to clarify the incidence of steroid-induced osteonecrosis among different collagen diseases and to evaluate the predictive factors for steroid-induced osteonecrosis in a prospective MRI study. Methods. We prospectively used MRI to study 337 eligible collagen disease patients requiring corticosteroid therapy and succeeded in examining 1199 joints (hips and knees) in 302 patients with MRI for at least one year starting immediately after the onset of corticosteroid therapy, a one-year follow-up rate of approximately 90%. The underlying collagen diseases included systemic lupus erythematosus (SLE) in 687 joints and a variety of other collagen diseases in 512 joints. Results. Incidence of osteonecrosis was significantly higher in SLE patients than in non-SLE patients (37% versus 21%, p=0.001). Logistic regression analysis revealed that adolescent and adult patients had a significantly higher risk of osteonecrosis compared with pediatric patients (odds ratio [OR]=13.2), that high daily corticosteroid dosage (more than 40 mg/day) entailed a significantly higher risk of osteonecrosis compared with the dosage less than 40 mg/day (OR=4.2), that SLE patients had a significantly higher risk of osteonecrosis compared with non-SLE patients (OR=2.6), and that male patients had a significantly higher risk of osteonecrosis compared with female patients (OR=1.6). Conclusion. These findings suggest that the incidence of steroid-induced osteonecrosis is different among underlying collagen diseases

Purpose

To evaluate the effectiveness of the perioperative erythropoietin administration, as an alternative to homologous banked blood transfusions, in total hip arthroplasty.

Background

No study compared the clinical results of the posterior-stabilized mobile-bearing knee with those of nonposterior-stabilized mobile-bearing knee in the same patients. The purpose of this study was to examine whether the clinical and radiographic results, range of motion, patients satisfaction, and complication rates would be better in the knees with a posterior-stabilized mobile-bearing knee than in the knees with a nonposterior-stabilized mobile-bearing knee.

Background. Previous data from our institution show that more than half of all prosthetic joint infections are due to S. aureus. A significant proportion of these bacteria may have an endogenous source. Detecting and treating asymptomatic S. aureus nasal carriers preoperatively has been shown to reduce the risk of infection. Material and Methods. This is an ongoing prospective study that started in March/2009 and involves primary total knee or hip arthroplasties candidates. So far preoperative nasal swab cultures were performed in 211(61%) out of 347 patients operated until April/2010. Carriers are identified and randomly chosen for preoperative treatment consisting of nasal mupirocin twice a day and daily cloro-hexidine baths in the 5 days that precede surgery. Antibiotic prophylaxis is cefazolin 24hours adding a single vancomycin dose in MRSA carriers. Results. Around 30% (64/211) of patients presented Saureus nasal carriage and 6 of them (9.4%) were methicilin-resistant. Infection rate was lower in the non-carriers: 1.36% (2/147). The group of 33 untreated carriers so far has the higher prevalence of infection (6.06%; Odds ratio=4.677; p=0.098). In the 31 treated carriers there was only one infection to date (3.23%; Odds ratio=2.371; p=0.463). The 136 patients control group in which no preoperative nasal culture was made registered 4 infections (2.94%; Odds ratio=2.197; p=0.356). Five out of the nine infections involved S. aureus. We further isolated 3 S. epidermidis, 1 enterococcus and 2 gram-negatives. Discussion. It seems that two S. aureus infections were due to endogenous contamination as the infecting bacteria possesses the exact same phenotype as the colonizing preoperative one (one untreated and one treated carrier). In other two S. aureus cases the seeding appears exogenous (a preoperative negative culture and a infecting bacteria different than the preoperative screening). One infection was registered in a non-studied patient. Accordingly, exogenous contamination seems responsible for at least 6 out of 9 infections. Conclusion. These preliminary results suggest that S. aureus colonization may be an endogenous risk factor for prosthetic joint infection that can be influenced. However exogenous contamination is still a major risk factor in our institution

BACKGROUND

Many patients who underwent a THA, report a feeling of more “physiological” hip and of faster recovery when bigger heads are used. The aim of this study is to evaluate the walking recovery of patients after THA with different head diameters by the means of gait analysis.

The aim of this study was to determine if patient reported outcome scores for arthroscopic meniscectomy are adversely affected by the degree of knee osteoarthritis or patient body mass index (BMI).

All patients who underwent arthroscopic meniscectomy within the NHS in Scotland between 6th February and 29th April 2012 were audited as part of the Scottish Government Musculoskeletal Knee Arthroscopy Audit and were eligible for inclusion within this study. A total of 270 patients returned both their pre-operative and post-operative EuroQol 5Q5D5L descriptive questionnaire and Knee injury and Osteoarthritis Outcomes Scores. Patients were stratified according to BMI, degree of osteoarthritis, history of injury, and duration of knee symptoms.

Pre-operative to post-operative EuroQol index scores [0.642±0.253 to 0.735±0.277, median±SD] and Knee injury and Osteoarthrtis Outcome Scores [44.63±18.78 to 62.28±24.94, median±SD] improved across all patients (p<0.0001). This was irrespective of degree of BMI, history of injury, or duration of symptoms. There was no such improvement in patients with moderate to severe osteoarthritis. Those patients with a BMI >35 kg/m2 had lower post-operative scores than the pre-operative scores of those of BMI <30 kg/m2.

Arthroscopic meniscectomy is beneficial regardless of patient BMI, duration of symptoms, history of injury, or in the presence of mild arthritis.
