Short versus conventional straight stem in uncemented total hip arthroplasty: functional outcomes up to 5 years and survival up to 12 years: secondary results of a randomized controlled trial.

BACKGROUND AND PURPOSE: To date, the mid- and long-term outcomes of the Collum Femoris Preserving (CFP) stem compared with conventional straight stems are unknown. We aimed to compare physical function at a 5-year follow-up and implant survival at an average of 10-year follow-up in an randomized controlled trial (RCT). METHODS: This is a secondary report of a double-blinded RCT in 2 hospitals. Patients aged 18-70 years with hip osteoarthritis undergoing an uncemented primary THA were randomized to a CFP or a Zweymüller stem. Patient-reported outcomes, clinical tests, and radiographs were collected at baseline, 2, 3, 4, and 5 years postoperatively. Primary outcome was the Hip disability and Osteoarthritis Outcome Score (HOOS) function in activities of daily living (ADL) subscale. Secondary outcomes were other patient-reported outcomes, clinical tests, adverse events, and implant survival. Kaplan-Meier and competing risk survival analyses were performed with data from the Dutch Arthroplasty Registry. RESULTS: We included 150 patients. Mean difference between groups on the HOOS ADL subscale at 5 years was -0.07 (95% confidence interval -5.1 to 4.9). Overall survival was 92% for the CFP and 96% for the Zweymüller stem. No significant difference was found. CONCLUSION: No significant differences were found in physical function at 5-year and implant survival at 10-year follow-up between the CFP and Zweymüller stems. When taking cup revisions into account, the CFP group showed clinically inferior survival.

Health-related quality of life of adult, non-surgically treated patients with idiopathic scoliosis and curves above 45°: a cross-sectional study at an average follow-up of 30 years.

BACKGROUND CONTEXT: Previous studies on the natural history of moderate to severe idiopathic scoliosis show contradictory results. Some studies reported an increased incidence of back pain and disability in severe curves, while other studies reported no difference in health-related quality of life (HRQoL) compared to age-matched adult controls. None of these studies addressed HRQoL using currently recommended and validated questionnaires. PURPOSE: To examine the long-term HRQoL in non-surgically treated adult idiopathic scoliosis patients with a curve of 45° or higher. METHODS: In this retrospective cohort study, all patients were retrospectively identified in the hospital's scoliosis database. Patients (1) with idiopathic scoliosis; (2) born before 1981 (to ensure 25-year follow-up after skeletal maturity); (3) with a curve of 45° or more by Cobb's method at the end of growth; and (4) no spinal surgical treatment were selected. Patients received digital questionnaires of the Short Form-36, Scoliosis Research Society-22, Oswestry Disability Index and Numeric Rating Scale. Outcomes of the SF-36 were compared with a national reference cohort. Additional measures with questions regarding choice of education and occupation were used. RESULTS: Forty-eight of 79 (61%) eligible patients completed the questionnaires, at an average follow-up time of 29.9 ± 7.7 years. Their average age was 51.9 ± 8.0, and median Cobb angle at adolescence was 48.5°. Five of the eight SF-36 subdomains were significantly lower in the scoliosis group compared to the nationwide cohort: physical functioning (73 vs 83, p = 0.011), social functioning (75 vs 84, p = 0.022), role physical functioning (63 vs 76, p = 0.002), role emotional functioning (73 vs 82, p = 0.032), and vitality (56 vs 69, p = < 0.001). The scoliosis-specific SRS-22r score of the patients was 3.7 ± 0.7 on a 0-5 scale. The mean NRS score for pain of all patients was 4.9 ± 3.2, and eight patients (17%) reported a NRS of 0 and 31 (65%) a NRS above 3. At the Oswestry Disability Index, 79% of the patients reported minimal disabilities. Thirty-three patients (69%) reported that their scoliosis had influenced their choice of education. Fifteen patients (31%) reported that their scoliosis had influenced their choice of work. CONCLUSION: Patients with idiopathic scoliosis and curves of 45° or higher have reduced HRQoL. Although many patients experience back pain, the disability reported on the ODI was limited. Scoliosis had noteworthy effect on choice of education.

Ninety-day complication rate based on 532 Latarjet procedures in Dutch hospitals with different operation volumes.

BACKGROUND: In this study, we aimed to provide insight into the 90-day complication rates following the Latarjet procedure. Data from 2015 were collected from multiple hospitals in the Netherlands, with different volumes of Latarjet procedures. Our second aim was to examine which patient and surgical factors were associated with complications. METHODS: We conducted a retrospective chart review of 13 hospitals between 2015 and 2022. Data regarding complications within 90 days of Latarjet procedures were extracted. The effect of sex, age, body mass index (BMI), smoking, previous shoulder operations, fixation material, hospital volume, screw size, and operation time on the complication rate was assessed by multivariable logistic regression analysis. RESULTS: Of the 532 included patients, 58 (10.9%) had complications. The most common complications were material failure (n = 19, 3.6%) and nerve injury (n = 13, 2.4%). The risk of complications was lower for male patients than for female patients (odds ratio, 0.40; 95% confidence interval, 0.21-0.77; P = .006). Age, BMI, smoking, previous shoulder operations, type of fixation material, hospital volume, screw size, and operation time were not associated with complications. CONCLUSION: The 90-day complication rate after the Latarjet procedure was 10.9% and was higher in female patients than in male patients. Age, BMI, smoking, previous shoulder operations, type of fixation material, hospital volume, screw size, and operation time did not affect complication rates. We advise setting up a national registry to prevent under-reporting of complications.

An individualized decision between physical therapy or surgery for patients with degenerative meniscal tears cannot be based on continuous treatment selection markers: a marker-by-treatment analysis of the ESCAPE study.

PURPOSE: Marker-by-treatment analyses are promising new methods in internal medicine, but have not yet been implemented in orthopaedics. With this analysis, specific cut-off points may be obtained, that can potentially identify whether meniscal surgery or physical therapy is the superior intervention for an individual patient. This study aimed to introduce a novel approach in orthopaedic research to identify relevant treatment selection markers that affect treatment outcome following meniscal surgery or physical therapy in patients with degenerative meniscal tears. METHODS: Data were analysed from the ESCAPE trial, which assessed the treatment of patients over 45 years old with a degenerative meniscal tear. The treatment outcome of interest was a clinically relevant improvement on the International Knee Documentation Committee Subjective Knee Form at 3, 12, and 24 months follow-up. Logistic regression models were developed to predict the outcome using baseline characteristics (markers), the treatment (meniscal surgery or physical therapy), and a marker-by-treatment interaction term. Interactions with p < 0.10 were considered as potential treatment selection markers and used these to develop predictiveness curves which provide thresholds to identify marker-based differences in clinical outcomes between the two treatments. RESULTS: Potential treatment selection markers included general physical health, pain during activities, knee function, BMI, and age. While some marker-based thresholds could be identified at 3, 12, and 24 months follow-up, none of the baseline characteristics were consistent markers at all three follow-up times. CONCLUSION: This novel in-depth analysis did not result in clear clinical subgroups of patients who are substantially more likely to benefit from either surgery or physical therapy. However, this study may serve as an exemplar for other orthopaedic trials to investigate the heterogeneity in treatment effect. It will help clinicians to quantify the additional benefit of one treatment over another at an individual level, based on the patient's baseline characteristics. LEVEL OF EVIDENCE: II.

Comparison of early migration patterns between a ceramic and polyethylene liner in uncemented Trabecular Titanium cups: a 2-year randomized controlled trial of 52 hips using radiostereometric analysis.

BACKGROUND AND PURPOSE: Ceramic liners may reduce early stability of uncemented acetabular components due to higher stiffness. However, the bone ingrowth capacities of porous trabecular titanium might compensate for this effect. This prospective randomized trial quantifies migration patterns of the Delta-TT cup, and compares polyethylene and ceramic liners. PATIENTS AND METHODS: Patients undergoing primary uncemented total hip arthroplasty with the Delta-TT cup and femoral stem with ceramic head were randomized to a polyethylene (n = 25) or ceramic (n = 28) liner. Radiostereometric analysis (RSA) radiographs, patient-reported hip function (HOOS-PS, OHS), and quality of life (EQ5D) were collected at baseline and 1.5, 3, 6, 12, and 24 months postoperatively. Model-based RSA was used to calculate 3D cup translation and rotation, and mixed models were used to compare effects over time between groups. RESULTS: At 2 years follow-up, Delta-TT cups showed similar mean proximal translation of 0.56 mm (95% CI 0.38-0.75) in the ceramic (CE) group and 0.54 mm (0.30-0.77) in the polyethylene (PE) group, with a between group effect of 0.02 mm (-0.20-0.23). Most cup migration occurred in the first 1.5 to 3 months, stabilizing within 6 months. Any between-group effects were ≤ 0.30 mm for translation and ≤ 0.45° for rotation. Improvements in patient-reported hip function and quality of life were similar in both groups. INTERPRETATION: Regardless of liner type, Delta-TT cups showed some initial migration and stabilized within 6 months, which seems promising for long-term fixation in both cup-liner constructs.

Posterolateral or direct lateral approach for cemented hemiarthroplasty after femoral neck fracture (APOLLO): protocol for a multicenter randomized controlled trial with economic evaluation and natural experiment alongside.

BACKGROUND AND PURPOSE: The posterolateral and direct lateral surgical approach are the 2 most common surgical approaches for performing a hemiarthroplasty in patients with a hip fracture. It is unknown which surgical approach is preferable in terms of (cost-)effectiveness and quality of life. METHODS AND ANALYSIS: We designed a multicenter randomized controlled trial (RCT) with an economic evaluation and a natural experiment (NE) alongside. We will include 555 patients ≥ 18 years with an acute femoral neck fracture. The primary outcome is patient-reported health-related quality of life assessed with the EQ-5D-5L. Secondary outcomes include healthcare costs, complications, mortality, and balance (including fear of falling, actual falls, and injuries due to falling). An economic evaluation will be performed for quality adjusted life years (QALYs). We will use variable block randomization stratified for hospital. For continuous outcomes, we will use linear mixed-model analysis. Dichotomous secondary outcome measures will be analyzed using chi-square statistics and logistic regression models. Primary analyses are based on the intention-to-treat principle. Additional as treated analyses will be performed to evaluate the effect of protocol deviations. Study summary: (i) Largest RCT addressing the health-related patient outcome of the main surgical approaches of hemiarthroplasty. (ii) Focus on outcomes that are important for the patient. (iii) Pragmatic and inclusive RCT with few exclusion criteria, e.g., patients with dementia can participate. (iv) Natural experiment alongside to amplify the generalizability. (v) The first study conducting a costutility analysis comparing both surgical approaches.

How are you doing in the eyes of your spouse? Level of agreement between the self-completed EQ-5D-5L and two proxy perspectives in an orthopaedic population: a randomized agreement study.

OBJECTIVES: To determine the level of agreement between both proxy versions and the self-completed EQ-5D-5L. DESIGN: A randomized agreement study. SETTING AND PARTICIPANTS: We recruited 120 patients (compos mentis) and their proxies at the orthopaedic outpatient clinic. Patients completed the regular EQ-5D-5L and their proxy completed the proxy version of the EQ-5D-5L and rated the patients' health from their own (proxy-proxy) perspective (i.e. how do you rate the health of the patient), and from the patient's (proxy-patient) perspective (i.e. how do you think the patient would rate their own health if they were able to). MEASURES: The primary outcome was the agreement between patients and their proxy, quantified as the intra class correlation coefficient for the EQ-5D-5L Utility score. RESULTS: Average Utility scores were 0.65 with the self completed EQ-5D-5L, versus 0.60 with the proxy-patient version and 0.58 with the proxy-proxy version. The ICC was 0.66 (95% CI 0.523, 0.753) for the proxy-patient perspective and 0.58 (95% CI 0.411, 0.697) for the proxy-proxy perspective. The mean gold standard score of the VAS-Health was 69.7 whereas the proxy-proxy perspective was 66.5 and the proxy-patient perspective was 66.3. CONCLUSION AND IMPLICATIONS: The proxy-patient perspective yielded substantial agreement with the self completed EQ-5D-5L, while the agreement with the proxy-proxy perspective was moderate. In this study population of patients without cognitive impairment, proxies tended to underestimate the quality of life of their relative.

Long Head of Biceps Tenotomy Is Not Inferior to Suprapectoral Tenodesis in Arthroscopic Repair of Nontraumatic Rotator Cuff Tears: A Multicenter, Non-inferiority, Randomized, Controlled Clinical Trial.

PURPOSE: To determine if long head of the biceps (LHB) tenotomy is not inferior to suprapectoral LHB tenodesis when performed in conjunction with arthroscopic repair of small- to medium-sized nontraumatic rotator cuff tears. METHODS: This multicenter, randomized, non-inferiority trial recruited 100 participants older than 50 years who had a supraspinatus and/or infraspinatus tear sagittally smaller than 3 cm and arthroscopically confirmed LHB pathology. During arthroscopic rotator cuff repair, we randomized 48 patients to undergo suprapectoral LHB tenodesis and 52 patients to undergo LHB tenotomy. Data were collected preoperatively and at 6 weeks, 3 months, and 1 year postoperatively. The primary outcome was non-inferiority of the Constant-Murley score (CMS) at 1-year follow-up. Secondary outcomes included the Dutch Oxford Shoulder Score; Disabilities of the Arm, Shoulder and Hand questionnaire; Popeye deformity; elbow flexion strength index; arm cramping pain; and quality of life (EQ-5D score). The integrity of the rotator cuff repair was assessed with magnetic resonance imaging. Differences between intervention groups were analyzed by mixed modeling. RESULTS: The mean CMS in the LHB tenotomy group improved from 44 (95% confidence interval [CI], 39-48) to 73 (95% CI, 68-79). In patients with LHB tenodesis, the mean CMS improved from 42 (95% CI, 37-48) to 78 (95% CI, 74-82). The difference between groups at 1-year follow-up was 4.8 (97.5% CI, -∞ to 11.4), with a P value for non-inferiority of .06. The secondary outcomes also improved over time, with no remarkable differences between groups. A Popeye deformity occurred in 33% of tenodesis patients and 47% of tenotomy patients (P = .17). Tenotomy was performed with a shorter operative time (73 minutes vs 82 minutes, P = .03). Magnetic resonance imaging showed a recurrent rotator cuff tear in 20% of all cases. CONCLUSIONS: Although statistically "inconclusive" regarding non-inferiority of the CMS at 1-year follow-up, any observed differences between patients with LHB tenotomy and those with LHB tenodesis in all outcome scores were small. LEVEL OF EVIDENCE: Level I, randomized controlled trial and treatment study.

Translation, cross-cultural and construct validity of the Dutch-Flemish PROMIS® upper extremity item bank v2.0.

PURPOSE: To develop a Dutch-Flemish translation of the PROMIS® upper extremity (PROMIS-UE) item bank v2.0, and to investigate its cross-cultural and construct validity as well as its floor and ceiling effects in patients with musculoskeletal UE disorders. METHODS: State of the art translation methodology was used to develop the Dutch-Flemish PROMIS-UE item bank v2.0. The item bank and four legacy instruments were administered to 205 Dutch patients with musculoskeletal UE disorders visiting an orthopedic outpatient clinic. The validity of cross-cultural comparisons between English and Dutch patients was evaluated by studying differential item functioning (DIF) for language (Dutch vs. English) with ordinal logistic regression models and McFadden's pseudo R2-change of ≥ 2% as critical value. Construct validity was assessed by formulating a priori hypotheses and calculating correlations with legacy instruments. Floor/ceiling effects were evaluated by determining the proportion of patients who achieved the lowest/highest possible raw score. RESULTS: Eight items showed DIF for language, but their impact on the test score was negligible. The item bank correlated, as hypothesized, moderately with the Dutch-Flemish PROMIS pain intensity item (Pearson's r = - 0.43) and strongly with the Disabilities of the Arm, Shoulder and Hand questionnaire, Subscale Disability/Symptoms (Spearman's ρ = - 0.87), the Functional Index for Hand Osteoarthritis (ρ = - 0.86), and the Michigan Hand Outcomes Questionnaire, Subscale Activities of Daily Living (ρ = 0.87). No patients achieved the lowest or highest possible raw score. CONCLUSIONS: A Dutch-Flemish PROMIS-UE item bank v2.0 has been developed that showed sufficient cross-cultural and construct validity as well as absence of floor and ceiling effects.

Can even experienced orthopaedic surgeons predict who will benefit from surgery when patients present with degenerative meniscal tears? A survey of 194 orthopaedic surgeons who made 3880 predictions.

OBJECTIVES: To examine the ability of surgeons to predict the outcome of treatment for meniscal tears by arthroscopic partial meniscectomy (APM) and exercise therapy in middle-aged patients. DESIGN AND SETTING: Electronic survey. Orthopaedic surgeon survey participants were presented 20 patient profiles. These profiles were derived from a randomised clinical trial comparing APM with exercise therapy in middle-aged patients with symptomatic non-obstructive meniscal tears. From each treatment group (APM and exercise therapy), we selected five patients with the best (responders) and five patients with the worst (non-responders) knee function after treatment. 1111 orthopaedic surgeons and residents in the Netherlands and Australia were invited to participate in the survey. INTERVENTIONS: For each of the 20 patient profiles, surgeons (unaware of treatment allocation) had to choose between APM and exercise therapy as preferred treatment and subsequently had to estimate the expected change in knee function for both treatments on a 5-point Likert Scale. Finally, surgeons were asked which patient characteristics affected their treatment choice. MAIN OUTCOMES: The primary outcome was the surgeons' percentage correct predictions. We also compared this percentage between experienced knee surgeons and other orthopaedic surgeons, and between treatment responders and non-responders. RESULTS: We received 194 (17%) complete responses for all 20 patient profiles, resulting in 3880 predictions. Overall, 50.0% (95% CI 39.6% to 60.4%) of the predictions were correct, which equals the proportion expected by chance. Experienced knee surgeons were not better in predicting outcome than other orthopaedic surgeons (50.4% vs 49.5%, respectively; p=0.29). The percentage correct predictions was lower for patient profiles of non-responders (34%; 95% CI 21.3% to 46.6%) compared with responders (66.0%; 95% CI 57.0% to 75.0%; p=0.01).In general, bucket handle tears, knee locking and failed non-operative treatment directed the surgeons' choice towards APM, while higher level of osteoarthritis, degenerative aetiology and the absence of locking complaints directed the surgeons' choice towards exercise therapy. CONCLUSIONS: Surgeons' criteria for deciding that surgery was indicated did not pass statistical examination. This was true regardless of a surgeon's experience. These results suggest that non-surgical management is appropriate as first-line therapy in middle-aged patients with symptomatic non-obstructive meniscal tears.

How do the costs of physical therapy and arthroscopic partial meniscectomy compare? A trial-based economic evaluation of two treatments in patients with meniscal tears alongside the ESCAPE study.

OBJECTIVES: To examine whether physical therapy (PT) is cost-effective compared with arthroscopic partial meniscectomy (APM) in patients with a non-obstructive meniscal tear, we performed a full trial-based economic evaluation from a societal perspective. In a secondary analysis-this paper-we examined whether PT is non-inferior to APM. METHODS: We recruited patients aged 45-70 years with a non-obstructive meniscal tear in nine Dutch hospitals. Resource use was measured using web-based questionnaires. Measures of effectiveness included knee function using the International Knee Documentation Committee (IKDC) and quality-adjusted life-years (QALYs). Follow-up was 24 months. Uncertainty was assessed using bootstrapping techniques. The non-inferiority margins for societal costs, the IKDC and QALYs, were €670, 8 points and 0.057 points, respectively. RESULTS: We randomly assigned 321 patients to PT (n=162) or APM (n=159). PT was associated with significantly lower costs after 24 months compared with APM (-€1803; 95% CI -€3008 to -€838). The probability of PT being cost-effective compared with APM was 1.00 at a willingness to pay of €0/unit of effect for the IKDC (knee function) and QALYs (quality of life) and decreased with increasing values of willingness to pay. The probability that PT is non-inferior to APM was 0.97 for all non-inferiority margins for the IKDC and 0.89 for QALYs. CONCLUSIONS: The probability of PT being cost-effective compared with APM was relatively high at reasonable values of willingness to pay for the IKDC and QALYs. Also, PT had a relatively high probability of being non-inferior to APM for both outcomes. This warrants further deimplementation of APM in patients with non-obstructive meniscal tears. TRIAL REGISTRATION NUMBERS: NCT01850719 and NTR3908.

Study protocol: Effectiveness of dual-mobility cups compared with uni-polar cups for preventing dislocation after primary total hip arthroplasty in elderly patients - design of a randomized controlled trial nested in the Dutch Arthroplasty Registry.

Background and purpose - Dislocation is the leading reason for early revision surgery after total hip arthroplasty (THA). The dual-mobility (DM) cup was developed to provide more stability and mechanically reduce the risk of dislocation. Despite the increased use of DM cups, high-quality evidence of their (cost-)effectiveness is lacking. The primary objective of this randomized controlled trial (RCT) is to investigate whether there is a difference in the number of hip dislocations following primary THA, using the posterolateral approach, with a DM cup compared with a unipolar (UP) cup in elderly patients 1 year after surgery. Secondary outcomes include the number of revision surgeries, patient-reported outcome measures (PROMs), and cost-effectiveness.Methods and analysis - This is a prospective multicenter nationwide, single-blinded RCT nested in the Dutch Arthroplasty Registry. Patients ≥ 70 years old, undergoing elective primary THA using the posterolateral approach, will be eligible. After written informed consent, 1,100 participants will be randomly allocated to the intervention or control group. The intervention group receives a THA with a DM cup and the control group a THA with a UP cup. PROMs are collected preoperatively, and 3 months, 1 and 2 years postoperatively. Primary outcome is the difference in number of dislocations between the UP and DM cup within 1 year, reported in the registry (revisions), or by the patients (closed or open reduction). Data will be analyzed using multilevel models as appropriate for each outcome (linear/logistic/survival). An economic evaluation will be performed from the healthcare and societal perspective, for dislocation and quality adjusted life years (QALYs).Trial registration - This RCT is registered at www.clinicaltrials.gov with identification number NCT04031820.

Remplissage With Bankart Repair in Anterior Shoulder Instability: A Systematic Review of the Clinical and Cadaveric Literature.

PURPOSE: To compare the clinical and biomechanical results of an arthroscopic Bankart repair alone with an arthroscopic Bankart repair combined with remplissage. METHODS: A literature search was performed on May 1, 2018, in PubMed and Embase for studies comparing an isolated arthroscopic Bankart repair and an arthroscopic Bankart repair with remplissage. The quality of the studies was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach and the Cochrane Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) checklist. Results regarding failures, biomechanical properties, and shoulder function were extracted. RESULTS: We included 13 studies (6 clinical and 7 biomechanical studies), and their overall quality was very low to low. In the biomechanical studies, adding a remplissage to the Bankart repair prevented engagement in all cadavers, resulted in more stiffness, and impaired the range of motion. Among clinical studies, all reported lower recurrence rates and most showed better shoulder function after a Bankart repair with remplissage compared with an isolated Bankart repair. The return-to-sport rates were mostly similar, whereas the loss of range of motion was often higher after a Bankart repair with remplissage. CONCLUSIONS: The addition of a remplissage procedure to a Bankart repair for managing small to medium Hill-Sachs lesions might be beneficial in reducing the risk of recurrent instability and improving shoulder function, without increasing the risk of complications. LEVEL OF EVIDENCE: Level III, systematic review of Level II and III studies.

Ten percent re-dislocation rate 13 years after the arthroscopic Bankart procedure.

PURPOSE: The aim of the present study was to determine the long-term outcome after the arthroscopic Bankart procedure, in terms of recurrent instability, shoulder function, glenohumeral arthropathy and patient satisfaction. METHODS: Patients who underwent the arthroscopic Bankart procedure between January 1999 and the end of December 2005 were invited to complete a set of Patient Reported Outcome Measures (PROMs) and visit the hospital for clinical and radiological assessment. PROMs included the Western Ontario Shoulder Instability Index (WOSI), the Oxford Shoulder Instability Score (OSIS) and additional questions on shoulder instability and patient satisfaction. Clinical assessment included the apprehension test and the Constant-Murley score. The Samilson-Prieto classification was used to assess arthropathy on standard radiographs. The primary outcome was a re-dislocation that needed reduction. Secondary outcomes in terms of recurrent instability included patient-reported subluxation and a positive apprehension test. RESULTS: Of 104 consecutive patients, 71 patients with a mean follow-up of 13.1 years completed the PROMs, of which 53 patients (55 shoulders) were also available for clinical and radiological assessment. Re-dislocations had occurred in 7 shoulders (9.6%). Subluxations occurred in 23 patients (31.5%) and the apprehension test was positive in 30 (54.5%) of the 55 shoulders examined. Median functional outcomes were 236 for WOSI, 45 for OSIS, and 103 for the normalized Constant-Murley score. Of all 71 patients (73 shoulders), 29 (39.7%) reported being completely satisfied, 33 (45.2%) reported being mostly satisfied and 8 (11%) reported being somewhat satisfied. Glenohumeral arthropathy was observed in 33 (60%) of the shoulders. CONCLUSION: Despite 10% re-dislocations and frequent other signs of recurrent instability, shoulder function and patient satisfaction at 13 years after arthroscopic Bankart repair were good. LEVEL OF EVIDENCE: Level IV.

Effect of Early Surgery vs Physical Therapy on Knee Function Among Patients With Nonobstructive Meniscal Tears: The ESCAPE Randomized Clinical Trial.

Importance: Despite recent studies suggesting arthroscopic partial meniscectomy (APM) is not more effective than physical therapy (PT), the procedure is still frequently performed in patients with meniscal tears. Objective: To assess whether PT is noninferior to APM for improving patient-reported knee function in patients with meniscal tears. Design, Setting, and Participants: Noninferiority, multicenter, randomized clinical trial conducted in 9 hospitals in the Netherlands. Participants were aged 45 to 70 years with nonobstructive meniscal tears (ie, no locking of the knee joint). Patients with knee instability, severe osteoarthritis, and body mass index greater than 35 were excluded. Recruitment took place between July 17, 2013, and November 4, 2015. Participants were followed up for 24 months (final participant follow-up, October 11, 2017). Interventions: Three hundred twenty-one participants were randomly assigned to APM (n = 159) or a predefined PT protocol (n = 162). The PT protocol consisted of 16 sessions of exercise therapy over 8 weeks focused on coordination and closed kinetic chain strength exercises. Main Outcomes and Measures: The primary outcome was change in patient-reported knee function on the International Knee Documentation Committee Subjective Knee Form (range, 0 to 100; from worse to best) from baseline over a 24-month follow-up period. The noninferiority margin was defined as a difference between treatment groups of 8 points and was assessed with a 1-sided α of .025. The primary analysis followed the intention-to-treat principle. Results: Among 321 patients who were randomized (mean [SD] age, 58 [6.6] years; 161 women [50%]), 289 (90%) completed the trial (161 women and 158 men). In the PT group, 47 participants (29%) had APM during the 24-month follow-up period, and 8 participants randomized to APM (5%) did not have APM. Over a 24-month follow-up period, knee function improved in the APM group by 26.2 points (from 44.8 to 71.5) and in the PT group by 20.4 points (from 46.5 to 67.7). The overall between-group difference was 3.6 points (97.5% CI, -∞ to 6.5; P value for noninferiority = .001). Adverse events occurred in 18 participants in the APM group and 12 in the PT group. Repeat surgery (3 in the APM group and 1 in the PT group) and additional outpatient visits for knee pain (6 in the APM group and 2 in the PT group) were the most frequent adverse events. Conclusions and Relevance: Among patients with nonobstructive meniscal tears, PT was noninferior to APM for improving patient-reported knee function over a 24-month follow-up period. Based on these results, PT may be considered an alternative to surgery for patients with nonobstructive meniscal tears. Trial Registration: ClinicalTrials.gov Identifier: NCT01850719.

Redislocation risk after an arthroscopic Bankart procedure in collision athletes: a systematic review.

BACKGROUND: The purpose of this review was to determine the redislocation risk for collision athletes after an arthroscopic Bankart repair and to compare the redislocation rate between collision athletes and noncollision athletes after an arthroscopic Bankart repair. METHODS: A PubMed and Embase query was performed, screening all relevant literature of arthroscopic Bankart procedures mentioning redislocation rates in collision athletes. Studies with a follow-up <2 years or lacking information on redislocation rates in collision athletes were excluded. We used the modified Coleman Methodology Score to assess the quality of included studies. Finally, the data in all the studies were combined and analyzed. RESULTS: There were 1012 studies screened on title and abstract, of which 111 studies were full-text screened, and finally 20 studies were included. Four studies reported on collision athletes only, whereas 16 compared collision with noncollision athletes. Fourteen studies reported increased redislocation rates for collision athletes in comparison to noncollision athletes (absolute risk difference varying from 0.4% to 28.6%), whereas 2 studies reported decreased rates (absolute risk differences of -6% and -2.4%). A combined analysis revealed that collision athletes have an increased absolute risk of 8.09 with 95% CI from 3.61 to 12.57% for development of postoperative instability in comparison to noncollision athletes (P = .001). CONCLUSION: Collision athletes have an increased risk for redislocation in comparison to noncollision athletes after an arthroscopic Bankart repair, although there were no differences in return to sport.

Pain and fatigue in adult patients with multiple osteochondromas: The Netherlands.

BACKGROUND: Multiple Osteochondromas (MO) is a rare genetic disorder characterised by the presence of numerous benign bone tumours, known as osteochondromas. Within the spectrum of debilitating symptoms associated with MO, pain is recognized as a major problem. Interestingly, our clinical observations suggest that fatigue is also a significant concern but has merely been touched upon in MO literature. This study aims to (1) assess the level of pain and fatigue in adult patients with MO; (2) compare fatigue in MO to healthy subjects and patients with Rheumatoid Arthritis (RA); (3) identify associated variables for pain and fatigue in patients with MO. METHODS: In this cross-sectional study, 353 adult MO patients completed a survey with validated questionnaires on pain, fatigue and psychosocial factors. Pain and fatigue were assessed with the Numeric Rating Scale (NRS), and fatigue was also measured with the Checklist Individual Strength (CIS). Fatigue (CIS) was compared with reference scores of healthy subjects and patients with RA, using a one-sample t-test. Multiple linear regression models for pain and fatigue were developed using a-priori selected independent variables based on a theoretical framework (ICF-model). RESULTS: Pain was reported by 87.8% (NRS = 3.19±2.6) and fatigue by 90.4% (NRS = 4.1±2.6) of patients with MO. Fatigue scores for MO (CIS = 84.1±15.3) were significantly higher (p<0.001) compared to reference scores of healthy subjects and patients with RA. The multivariable analysis for pain provided a final regression model with six variables (R2 = 0.445, p<0.001) of which fear avoidance beliefs and fatigue had the strongest association. For the fatigue models NRS (R2 = 0.455, p<0.001) and CIS (R2 = 0.233, p<0.001), the strongest associations were found with anxiety and depression respectively. CONCLUSIONS: Pain and fatigue are highly prevalent in patients with MO. Fatigue is significantly higher compared to healthy subjects and patients with RA. Several variables associated with pain and fatigue have been identified that could help improve multidisciplinary treatment plans.

Heath-related quality of life and functional outcomes in patients with congenital or juvenile idiopathic scoliosis after an average follow-up of 25 years: a cohort study.

BACKGROUND CONTEXT: Congenital and juvenile scoliosis are both early-onset deformities that develop before the age of 10. Children are treated to prevent curve progression and problems in adulthood such as back pain and a decreased quality of life but literature on long-term outcomes remains scarce. PURPOSE: To evaluate the health-related quality of life (HRQoL) and potential disability of children with congenital scoliosis (CS) or juvenile idiopathic scoliosis (JIS) after a minimum of 20 years follow-up. STUDY DESIGN: Comparative cohort study. PATIENT SAMPLE: A consecutive cohort of CS and JIS patients were retrospectively identified from a single-center scoliosis database. Patients born between 1968 and 1981 and treated during skeletal growth were eligible for participation. OUTCOME MEASURES: HRQoL (SF-36, SRS-22r, ODI). METHODS: The primary aim was to evaluate the HRQoL of CS and JIS patients using the general SF-36 questionnaire. Both patient cohorts were compared with age-matched national norms. The secondary aim was to analyze the differences between conservatively and surgically treated patients using the scoliosis-specific Scoliosis Research Society-22r questionnaire (SRS-22r) and the Oswestry Disability Index (ODI). T-tests were used for statistical comparison. RESULTS: In total, 114 patients (67% of the eligible patients) completed the questionnaire, with a mean follow-up of 25.5±5.5 years after their final clinical follow-up. Twenty-nine patients with CS were included with a mean age of 44.4±3.8 years (79.3% female), and 85 patients with JIS with a mean age of 43.7±4.2 years (89.4% female). Of the SF-36 domains, only the vitality score (60.6±18.0 for CS and 58.1±17.6 for JIS cohort) and mental health score (70.0±18.4 for CS and 72.1±18.1 for JIS cohort) were significantly lower compared with the general population (68.6±19.3 for vitality, and 76.8±17.4 for mental health). These decreased scores were larger than the determined minimum clinically important difference threshold of 4.37. Surgically treated JIS patients had a significantly lower score on the SRS-22r pain domain than their nonsurgically treated peers (3.6±0.9 vs 4.1±0.7l p=.019). Surgically treated CS patients had a significantly higher score on the SRS-22r mental health domain than their nonsurgically treated peers (4.3±0.5 vs 3.5±1.0; p=.023). No significant differences were found in the other domains. CONCLUSIONS: Except for vitality and mental health domains, congenital and juvenile idiopathic scoliosis patients treated during skeletal growth had similar HRQoL on most SF-36 domains in adulthood compared with national norms. Surgical treated JIS patients experienced more pain compared with brace treated patients, while braced CS patients had a significantly lower mental scores compared with surgical treated patients. These long-term outcomes are essential to inform patients and can guide shared decision-making between clinicians and patients.
