RESUMO
PURPOSE: To determine whether machine learning (ML) techniques developed using registry data could predict which patients will achieve minimum clinically important difference (MCID) on the International Hip Outcome Tool 12 (iHOT-12) patient-reported outcome measures (PROMs) after arthroscopic management of femoroacetabular impingement syndrome (FAIS). And secondly to determine which preoperative factors contribute to the predictive power of these models. METHODS: A retrospective cohort of patients was selected from the UK's Non-Arthroplasty Hip Registry. Inclusion criteria were a diagnosis of FAIS, management via an arthroscopic procedure, and a minimum follow-up of 6 months after index surgery from August 2012 to June 2021. Exclusion criteria were for non-arthroscopic procedures and patients without FAIS. ML models were developed to predict MCID attainment. Model performance was assessed using the area under the receiver operating characteristic curve (AUROC). RESULTS: In total, 1,917 patients were included. The random forest, logistic regression, neural network, support vector machine, and gradient boosting models had AUROC 0.75 (0.68-0.81), 0.69 (0.63-0.76), 0.69 (0.63-0.76), 0.70 (0.64-0.77), and 0.70 (0.64-0.77), respectively. Demographic factors and disease features did not confer a high predictive performance. Baseline PROM scores alone provided comparable predictive performance to the whole dataset models. Both EuroQoL 5-Dimension 5-Level and iHOT-12 baseline scores and iHOT-12 baseline scores alone provided AUROC of 0.74 (0.68-0.80) and 0.72 (0.65-0.78), respectively, with random forest models. CONCLUSIONS: ML models were able to predict with fair accuracy attainment of MCID on the iHOT-12 at 6-month postoperative assessment. The most successful models used all patient variables, all baseline PROMs, and baseline iHOT-12 responses. These models are not sufficiently accurate to warrant routine use in the clinic currently. LEVEL OF EVIDENCE: Level III, retrospective cohort design; prognostic study.

PURPOSE: To investigate changes in sexual function and activity after arthroscopic hip surgery for femoroacetabular impingement using the United Kingdom Non-Arthroplasty Hip Registry dataset. Subanalyses were performed between males and females, and patients over 40 and under 40 years old. METHODS: Patients who had arthroscopic hip surgery between January 1, 2012, and October 31, 2020, were aged over 16, and completed the relevant patient-reported outcome measures were included. Question 9 of the International Hip Outcome Tool-12 (sexual activity question [SAQ]) refers to problems with sexual activity, and responses to this were compared before surgery and at 6 and 12 months after surgery. Subanalyses were also performed, including SAQ scores by patients' sex or age. SAQ scores were correlated with Euroqol-5 dimension-5 level self-reporting tool (EQ-5D-5L) scores using Spearman's rank coefficient. RESULTS: SAQ was answered by 2,547 patients before and at 6 months after surgery (62.3% female, median age = 36.2, interquartile range [IQR] = 29-44 years) and by 2,314 at 12 months (61.9% female, median age = 36.2, IQR = 29-44 years). Scores for sexual activity increased from 35.0 before surgery to 70.0 at 6 months (P < .001) and were maintained at 12 months (P < .001). Female patients demonstrated a significantly greater improvement in their scores for sexual function from before surgery (median = 30.0, IQR = 14-50) to 6 months (median = 60, IQR = 28-86, P < .001) and 12 months (median = 62.0, IQR = 29-90, P < .001), compared to male patients (preoperative median = 50.0, IQR 25-84; 6-month median = 80, IQR = 45-97; 12-month median = 80, IQR = 41-98). The effect of age on improvements in sexual function did not demonstrate a significant difference. A significant positive correlation was found between improvements in sexual function and quality of life, as measured by the EQ-5D-5L, at 6 and 12 months (P < .001). CONCLUSIONS: Hip arthroscopy for symptomatic femoroacetabular impingement produces an improvement in sexual function and activity. Scores for sexual function improved regardless of patient age or sex; however, female patients experienced a greater improvement in sexual function than males. LEVEL OF EVIDENCE: Level III, Retrospective cohort study.

PURPOSE: To evaluate the current body of evidence surrounding the diagnosis, management, and clinical outcomes of adhesions that developed after hip arthroscopy (HA). METHODS: A systematic search of the MEDLINE, Embase, Web of Science, and CENTRAL (Cochrane Central Register of Controlled Trials) databases was designed and conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Eligible studies included patients with confirmed adhesions after HA that reported one or more of the following: (1) diagnostic procedures and criteria used; (2) indications for and details surrounding surgical management; and (3) clinical outcomes after the operative management of adhesions (e.g., patient-reported outcome measures). RESULTS: Nineteen studies involving a total of 4,145 patients (4,211 hips; 38% female sex) were included in this review. The quality of evidence was found to be fair for both comparative studies (mean, 17; range, 13-21) and noncomparative studies (mean, 10; range, 5-12) according to the Methodological Index for Non-randomized Studies (MINORS) instrument, with the level of evidence ranging from IIB to IV. Adhesions were often diagnosed intraoperatively at the time of revision surgery (10 of 19 studies, 53%), with only 3 studies specifying the criteria used to adjudicate adhesions. The most common indication for operative management (i.e., release or lysis of adhesions) was persistent pain (9 of 19, 47%), but this was often grossly stated for revision HA rather than being specific to adhesions. Patient-reported outcome measures were the most reported postoperative outcomes (9 of 19, 47%) and generally showed significant improvement from preoperative assessment across the short-term follow-up period (range, 24.5-38.1 months). There was a paucity of objective measures of clinical improvement (3 of 19, 16%) and of mid- and long-term follow-up (i.e., 5-7 years and ≥10 years, respectively). CONCLUSIONS: Despite the growing body of evidence suggesting that adhesions are highly contributory to revision HA, there is ambiguity in the diagnostic approach and indications for operative management of adhesions. Additionally, although the operative management of adhesions after HA has shown satisfactory clinical outcomes in the short term, there is a paucity of research elucidating the mid- to long-term outcomes, as well as minimal use of objective assessment of clinical improvement (e.g., biomechanics). LEVEL OF EVIDENCE: Level IV, systematic review of Level II to IV studies.
RESUMO
PURPOSE: We conducted a retrospective analysis of prospectively collected data to evaluate (1) the extent of surgical correction following minimally invasive periacetabular osteotomy, (2) improvements in functional outcomes and any potential predictors for favourable outcome, and (3) complications after minimally invasive periacetabular osteotomy. METHODS: A total of 352 minimally invasive periacetabular osteotomy procedures were performed on 312 hip dysplasia patients between 2013 and 2020. Radiological parameters such as lateral centre edge angle, acetabular index, and Tönnis grade of arthritis were calculated. Patients also completed a range of patient reported outcome measures. Wilcoxon signed-rank tests were performed to assess for differences between patient reported outcome measures and radiological outcomes across the follow-up periods. Univariate linear regression and logistic regression were used to assess for predictors of change in functional outcome. RESULTS: Patients had a significant correction in mean lateral centre edge angle from 17.2° to 35.3° (p < 0.001) and mean acetabular index from 13.2° to - 0.82°. At one year follow-up all patient reported outcome measures were significantly greater than their baseline measurements and this improvement was maintained at two years. Changes in patient reported outcome measures were independent of radiological parameters such as change in the lateral centre edge angle and acetabular index, pre-operative Tönnis grade, and patient factors such as age and sex. A total of 5.11% of patients developed post-operative complications, with four requiring posterior column fixation. Four patients (1.12%) needed a total hip replacement. CONCLUSION: Minimally invasive periacetabular osteotomy is a safe procedure that provides significant functional outcome improvements following surgery at six months which is maintained at two years. More than three-fourths of patients achieved improvement of iHOT-12 score beyond the minimal clinically important difference and more than half of the patients achieved substantial clinical benefit for iHOT-12 score.

PURPOSE: Results from recent randomised controlled trials demonstrate the superiority of surgery over physiotherapy in patients with femoroacetabular impingement (FAI) of the hip in early follow-up. However, there is paucity of evidence regarding which factors influence outcomes of FAI surgery, particularly notable is the lack of information on the effect of impingement subtype (cam or pincer or mixed) on patient reported outcomes measures (PROMs). This study aims to evaluate the early outcomes of hip arthroscopy for FAI, and their determinants. METHODS: This is a retrospective analysis of prospectively collected data from the UK Non-Arthroplasty Hip Registry (NAHR) of patients undergoing arthroscopic intervention for FAI between 2012 and 2019. The null hypothesis was that there is no difference in PROMs, based on morphological subtype of FAI treated or patient characteristics, at each follow-up timepoint. The outcome measures used for the study were the iHOT-12 score and the EQ5D Index and VAS 6- and 12-month follow-up. RESULTS: A cohort of 4963 patients who underwent arthroscopic treatment of FAI were identified on the NAHR database. For all FAI pathology groups, there was significant improvement from pre-operative PROMs when compared to those at 6 and 12 months. Overall, two-thirds of patients achieved the minimum clinically important difference (MCID), and almost half achieved substantial clinical benefit (SCB) for iHOT-12 by 12 months. Pre-operatively, and at 12-month follow-up, iHOT-12 scores were significantly poorer in the pincer group compared to the cam and mixed pathology groups (p < 0.01). Multivariable analysis revealed PROMS improvement in the setting of a higher-grade cartilage lesion. CONCLUSION: This registry study demonstrates that hip arthroscopy is an effective surgical treatment for patients with symptomatic FAI and results in a statistically significant improvement in PROMs which are maintained through 12 months follow-up. LEVEL OF EVIDENCE: III.

BACKGROUND: Prosthetic joint infection (PJI) is a devastating complication. Studies have suggested reduction in PJI with the use of ceramic bearings. METHODS: Adult patients who underwent total hip arthroplasty (THA) using an uncemented acetabular component with ceramic-on-ceramic (CoC), ceramic-on-polyethylene (CoP), or metal-on-polyethylene (MoP) bearing surfaces between 2002 and 2016 were extracted from the National Joint Registry for England, Wales, Northern Ireland, and the Isle of Man. A competing risk regression model to investigate predictors of each revision outcome was used. Time-to-event was determined by duration of implantation since primary surgery with competing risks being death or revision. The results were adjusted for age, gender, American Association of Anaesthesiologists grade, body mass index, surgical indication, intraoperative complications, and implant data. RESULTS: In total, 456,457 THAs (228,786 MoP, 128,403 CoC, and 99,268 CoP) were identified. Multivariable modeling showed that the risk of revision for PJI was significantly lower with CoC (risk ratio 0.748, P < .001) and CoP (risk ratio 0.775, P < .001) compared to MoP. Significant reduction in risk of aseptic and all-cause revision was also seen. The significant protective effect of ceramic bearing was predominantly seen 2 years after implantation. Aseptic revision beyond 2 years reduced by 18.1% and 24.8% for CoC and CoP (P < .001), respectively. All-cause revision rate beyond 2 years reduced by 21.6% for CoC and 27.1% for CoP (P < .001) CONCLUSION: This study demonstrates an association between the use of ceramic as part of the bearing, with lower rates of revision for all causes, revision for infection, and revision for aseptic causes, supporting ceramic bearings in THA.

PURPOSE: To provide an up-to-date evidence-based review of hip arthroscopy for patients with borderline developmental dysplasia of the hip (BDDH). METHODS: Literature describing hip arthroscopy in patients with BDDH was systematically identified from PubMed, EMBASE, and Cochrane Library using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. All studies that involved BDDH and not just those reporting their clinical outcomes were included. Methodological Index for Non Randomized Studies criteria and Newcastle-Ottawa Scale were used to assess the quality of studies. The definition of BDDH, operative technique, correlation with labrum and/or cartilage lesions, outcome, and factors associated with poor outcome were collected and analyzed. RESULTS: Assessment of the articles yielded 28 studies involving 1502 hips that were included for final analysis. There were no studies with a high risk of bias. BDDH was defined as lateral center-edge angle of 20° to 25° in most studies. Hip arthroscopy for BDDH showed an improvement in the weighted mean postoperative modified Harris Hip Score, from 60.2 to 81.7, a relatively high rate of acquisition of minimal clinically important difference of 79.5% to 87%, and had 1.0% rate of complications. Eleven studies reported on all the patients undergoing a capsular plication. Four studies reported that BDDH was associated with cartilage damage on the femoral head. Age older than 35 or 42 years and ≥20° of femoral anteversion were reported as risk factors for poor outcomes. CONCLUSIONS: Hip arthroscopy for BDDH with capsular plication provides improvement in patient-reported outcome measures and a relatively high rate of acquisition of minimal clinically important difference with a low rate of complications in the shorter term. BDDH may be associated with cartilage damage on the femoral head. Female sex is a factor related to good outcomes, whereas older age, excessive femoral anteversion, and anterior undercoverage of acetabulum are risk factors related to poorer outcomes. LEVEL OF EVIDENCE: Level IV, systematic review of Level III to IV studies.

Readmission after hip arthroscopic surgery is an undesired and unusual event. The causes may range from wound-related issues, deep infection, increasing pain, complications of surgery, to medical events. It adds to the economic burden of the procedure and causes unnecessary anguish to the patients and indeed clinicians. It is also one of the less-studied areas of hip arthroscopic surgery because of its rarity. There would be benefit in being able to identify the risk factors of readmission such that pre-emptive measures can be put in place to prevent or indeed counsel the patients before the surgery. In certain cases, readmission may remain an unpreventable event. In our experience, the readmission rate after hip arthroscopy is 0.5%, whereas patients with elevated body mass index are at greater risk.

PURPOSE: Our study aimed to identify the complications of hip arthroscopies with particular emphasis on the 30-day readmission rate; 90-day deep vein thrombosis (DVT) and pulmonary embolism (PE) rate and mortality rate; revision hip arthroscopy rate; and in particular, survivorship with conversion to total hip replacement (THR) as the endpoint. METHODS: The records of patients undergoing hip arthroscopy were extracted from the administrative hospital admissions database covering all admissions to the National Health Service hospitals in England using ICD-10 (International Statistical Classification of Diseases and Related Health Problems, 10th Revision) and OPCS-4 (Office of Population Censuses and Surveys Classification of Surgical Operations and Procedures, fourth revision) codes. RESULTS: A total of 6,395 hip arthroscopies were included in the study period. The 30-day readmission rate was 0.5%; both the 90-day DVT rate and PE rate were 0.08%; and the 90-day mortality rate was 0.02%. THR was performed in 680 patients (10.6%) at a mean of 1.4 years after the index operation, and 286 patients (4.5%) underwent revision hip arthroscopy at a mean of 1.7 years. Kaplan-Meier survival analysis showed an 8-year survival rate of 82.6% (95% confidence interval [CI], 80.9% to 84.2%), whereas Cox proportional hazard analysis adjusting for age, gender, and Charlson comorbidity score showed an 8-year survival rate of 86%. Female patients had a 1.68 times (95% CI, 1.41 to 2.01) higher risk of conversion to THR than male patients, and patients aged 50 years or older had a 4.65 (95% CI, 3.93 to 5.49) times higher risk of requiring hip replacement than patients younger than 50 years. CONCLUSIONS: In this large series of 6,395 hip arthroscopies looking at the national data from the English National Health Service, our null hypothesis has been supported, and we have determined that the rate of short-term complications, in particular the risk of DVT and PE after this operation, is low. Higher age and female gender are significant predictors of conversion to THR, with Cox proportional hazard analyses showing a survivorship rate of 86% at 8 years after adjustment for confounding variables. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

BACKGROUND AND PURPOSE: Enhanced Recovery (ER) is a well-established multidisciplinary strategy in lower limb arthroplasty and was introduced in our department in May 2008. This retrospective study reviews short-term outcomes in a consecutive unselected series of 3,000 procedures (the "ER" group), and compares them to a numerically comparable cohort that had been operated on previously using a traditional protocol (the "Trad" group). METHODS: Prospectively collected data on surgical endpoints (length of stay (LOS), return to theater (RTT), re-admission, and 30- and 90-day mortality) and medical complications (stroke, gastrointestinal bleeding, myocardial infarction, and pneumonia within 30 days; deep vein thrombosis and pulmonary embolism within 60 days) were compared. Results ER included 1,256 THR patients and 1,744 TKR patients (1,369 THRs and 1,631 TKRs in Trad). The median LOS in the ER group was reduced (3 days vs. 6 days; p = 0.01). Blood transfusion rate was also reduced (7.6% vs. 23%; p < 0.001), as was RTT rate (p = 0.05). The 30-day incidence of myocardial infarction declined (0.4% vs. 0.9%; p = 0.03) while that of stroke, gastrointestinal bleeding, pneumonia, deep vein thrombosis, and pulmonary embolism was not statistically significantly different. Mortality at 30 days and at 90 days was 0.1% and 0.5%, respectively, as compared to 0.5% and 0.8% using the traditional protocol (p = 0.03 and p = 0.1, respectively). INTERPRETATION: This is the largest study of ER arthroplasty, and provides safety data on a consecutive unselected series. The program has achieved a statistically significant reduction in LOS and in cardiac ischemic events for our patients, with a near-significant decrease in return to theater and in mortality rates.

OBJECTIVE: The chronicity of juvenile idiopathic arthritis (JIA) into adulthood and attendant potential disability may adversely influence educational attainment and the ability to secure and maintain gainful employment. We undertook this study to investigate the effects of patient- and disease-specific factors on education and employment outcomes in a group of adult patients with JIA. METHODS: We performed a cross-sectional study of 103 consecutive adults attending a JIA continuity clinic, and patients who consented completed questionnaires relating to educational achievement, employment status, and functional disability (the Health Assessment Questionnaire disability index [HAQ DI]), and, for those who were employed, the rheumatoid arthritis Work Instability Scale. We used the structural equation modeling technique to study key patient and disease variables for employment in adults with JIA. RESULTS: The median age of patients was 24 years (range 17-71 years) with median disease duration of 19 years (range 7-67 years). Functional disability (the mean HAQ DI score) was significantly lower in patients who were employed (P = 0.03) and in those with oligoarticular JIA (t = 2.29, P = 0.02). Educational achievement was not influenced by JIA subtype (F = 1.18, P = 0.33). Educational achievement measured by General Certificate of Secondary Education (GCSE) grades had a positive effect on the type of job achieved in later life (F = 11.63, P = 0.001), with greater success leading to more professional or managerial posts. In the complex structural equation model, job stability was influenced positively by educational achievement measured by GCSE grades and negatively by the HAQ DI score (t = 10.94, P = 6.36 × 10(-16) ). CONCLUSION: Educational attainment is key to successful employability and is influenced by functional disability rather than by JIA subtype. These findings have implications for choice of occupation and delivery of career advice to aid decision making by young people with JIA.

BACKGROUND: Although a large number of athletes' returns to sports after hip arthroscopic surgery for femoroacetabular impingement (FAI), it is not clear if they do so to the preinjury level and whether professional athletes (PA) are more likely to return to the preinjury level compared with recreational athletes (RA). QUESTIONS/PURPOSES: We therefore compared (1) the time taken to return to the preinjury level of sport between professional and recreational athletes; (2) the degree of improvement in time spent in training and competitive activities after arthroscopic surgery for FAI; and (3) the difference in trend of improvement in hip scores. METHODS: We prospectively followed 80 athletes (PA = 40, RA = 40; mean age, 35.7 years; males = 50, females = 30; mean followup, 1.4 years; range, 1-1.8 years) who underwent hip arthroscopy for FAI. We measured the time to return to sports; training time and time in competition; and the modified Harris hip score and the nonarthritic hip score. RESULTS: There was a 2.6-fold improvement in the training time (from 7.8 to 20 hours per week) and a 3.2-fold increase in time in competition (from 2.5 to 7.9 hours per week) 1 year after surgery. The mean time to return to sporting activities was 5.4 months, which was lower for PA (4.2) as compared with RA (6.8). Eighty-two percent (66) (PA = 88% [35] versus RA = 73% [29]) returned to their preinjury level of sport within 1 year of surgery. CONCLUSIONS: The data suggest PA may show quicker return to sports than RA but the hip scores and rate of return to sports are similar.

This is a prospective study of 26 patients (29 hips) on the patterns of change in the Bone Mineral Density (BMD) in various zones of the femoral neck and proximal femur five years after hip resurfacing. We have found that BMD continues to positively change up to five years after hip resurfacing. This was observed primarily in the trochanteric and superior neck regions. In both these regions BMD had decreased by up to 10% at six-weeks and three-months after surgery and then had recovered to preoperative level by one year. A regression analysis to assess the influence of age, gender, BMI, preoperative BMD, component size and orientation revealed that the best predictor of change in BMD at five years in the trochanteric area was acetabular component inclination.

BACKGROUND AND PURPOSE: Our unit started to use routine multimodal techniques to enhance recovery for hip and knee arthroplasty in 2008. We have previously reported earlier discharge, a trend toward a reduction in complications, and a statistically significant reduction in mortality up to 90 days after surgery. In this study, we evaluated the same cohort to determine whether survival benefits were maintained at 2 years. PATIENTS AND METHODS: We prospectively evaluated 4,500 unselected consecutive total hip and knee replacements. The first 3,000 underwent a traditional protocol (TRAD) and the later 1,500 underwent an enhanced recovery protocol (ER). Mortality data were collected from the Office of National Statistics (UK). RESULTS: There was a difference in death rate at 2 years (TRAD vs. ER: 3.8% vs. 2.7%; p = 0.05). Survival probability up to 3.7 years post surgery was significantly better in patients who underwent an ER protocol. INTERPRETATION: This large prospective case series of unselected consecutive patients showed a reduction in mortality rate at 2 years following elective lower-limb hip and knee arthroplasty following the introduction of a multimodal enhanced recovery protocol. This survival benefit supports the routine use of an enhanced recovery program for hip and knee arthroplasty.

Femoral malversion is an under-recognized contributor to hip pain in younger adults. Under treatment is often a contributor to poor outcomes in hip preservation surgery. We reviewed the literature to analyse the outcomes of proximal femoral derotation osteotomy as a treatment for femoral malversion as well as propose our own management algorithm for treating such patients. A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines searching four databases (PubMed, CINALH, MEDLINE and EMBASE) for studies investigating the outcomes of derotation osteotomy in treating malversion. Nine studies were found encompassing 229 hips. At a mean follow-up of 39.9 months across the studies, there were only two conversions (1%) to total hip arthroplasty and four revision cases in total. Seven of the nine studies reported improved functional outcomes in their cohorts, with the mean Harris hip score improved from 63.7 to 87.3 where reported. There is a paucity of literature around the outcomes of proximal femoral derotation osteotomy. However, both the evidence available and the authors' experience suggest that consideration of femoral malversion is an essential component of hip preservation surgery, improving functional outcomes in cases of excessive femoral anteversion and femoral retroversion.
RESUMO
BACKGROUND: The decision to offer orthopaedic surgery to patients with metastatic bone disease is often difficult and requires an understanding of the underlying disease, the patient's needs or wishes, the expected outcomes and the principles of surgery. AIM: We aimed to look at the literature to support the role of orthopaedic surgery for skeletal metastasis in improving key outcomes such as pain, quality of life and physical functioning. DESIGN: Review article. DATA SOURCES: The 'Dialog Datastar' database was used to access Medline and other resources from 1951 to December 2009 using keywords 'Metasta$' AND 'Bone or Skeletal' AND 'Results Or Outcome Or Surg$ Or Management'. RESULTS: The majority of the studies that have looked at these key outcomes are limited by their design and their use of non-validated outcome measures. This study has detailed the measures to assess outcome, predict survival, predict fracture and how to arrive at key decisions, such as when to operate and when not to operate on these patients. CONCLUSION: Timely and appropriate surgical intervention reliably alleviates pain and improves quality of life and can be undertaken with few complications in most patients. Although most procedures can be undertaken by non-specialists, consultation with other members of the multidisciplinary team is mandatory, and in complex cases, referral to a specialist orthopaedic oncology centre can be helpful.

BACKGROUND: The best timing for patient visits after revision TKA is unclear. Predictors of pain and function reported in the literature typically look at the influence at a given time that might not be ideal if the score is not at a peak or the earliest possible time. Moreover, most reports of predictors include revisions for infection, which typically have a poorer outcome, or for other indications with variable outcome. QUESTIONS/PURPOSES: We therefore determined (1) the trend of recovery after revision TKA to determine the best time to measure the peak patient-reported pain and function scores and (2) the influence of comorbidities and age on the patterns of recovery. METHODS: We prospectively followed 120 patients who had revision TKAs from 2003 to 2008. The patients were assessed within 6 weeks before surgery and at 12 weeks, 1 year, and annually thereafter. We obtained WOMAC and SF-36 scores at each visit. We used a linear mixed model analysis to assess predictors. The minimum followup was 2 years (mean, 3 years; range, 2-7 years). RESULTS: The majority of improvements in the WOMAC and SF-36 scores occurred during the first year after surgery after which the scores stabilized. One of the seven independent preoperative variables studied (comorbidities) predicted a trend toward improvement of WOMAC pain, WOMAC function, and SF-36 bodily pain scores. The greater the numbers of comorbidities, the worse were the scores. Age, gender, BMI, indication for surgery, and surgeon did not independently influence the WOMAC or SF-36. CONCLUSION: Our data suggest that one of the times for patient visits after revision TKA should be 1 year after surgery. This time allows for key discrimination of implant performance. The data also confirm that patients with a greater number of comorbidities had less functional benefit from revision surgery. LEVEL OF EVIDENCE: Level II, prognostic study.

PURPOSE: The aim of this study was to compare the outcome of hip arthroscopy for femoroacetabular impingement (FAI) between athletes and non-athletes. METHODS: The authors prospectively collected data on 122 patients, the largest comparative series reported, who underwent hip arthroscopy for FAI. Of these, 80 actively participated in sporting activities (athletes), while 42 did not (non-athletes). Patients were asked to complete questionnaires for the modified Harris hip score (MHHS), non-arthritic hip score (NAHS), patient satisfaction on a visual analogue scale (VAS). This was collected immediately before surgery, and at 6 weeks, 6 months and 1 year after the procedure. The responses to the MHHS questionnaire were used to calculate the quality-of-life (QoL) score using the Rosser index matrix. RESULTS: A significant improvement in the MHHS, NAHS and QoL was observed at 6 weeks, 6 months and 1 year after surgery (p<0.001). The 6-week MHHS (p=0.01) and NAHS (p=0.04) for the athletes were significantly better as compared with non-athletes. However, the 6-month and 1-year MHHS, NAHS and QoL scores were statistically similar for both groups. CONCLUSIONS: In this large, prospective series of patients we have demonstrated the positive impact of arthroscopic surgery for FAI in both the athletic and non-athletic population. Arthroscopic management of FAI is thus not the sole domain of the athletic patient. Non-athletes can do just as well.

PURPOSE: This study attempts to quantify the influence of constraint and various indications upon functional outcome following aseptic first-time revision knee arthroplasty. METHODS: A single-centre prospective study was performed to examine the outcome for 175 consecutive total revision knee replacements performed between 2003 and 2008 with a minimum follow-up of 2 years. Patient-reported outcome data were used to determine the influence of final level of component constraint, its relationship with primary indication for surgery and the predictor variable for functional outcome at 1 year. RESULTS: All patients were found to have a significant improvement for WOMAC pain, function and stiffness score and physical functioning, role physical, bodily pain and social functioning components of SF-36 score. About 69% were satisfied with the overall procedure. WOMAC function, pain and stiffness score was significantly worse for patients revised for instability (27%) compared to that for aseptic loosening (46%). A significantly higher proportion of patients were satisfied with the procedure, had a better quality of life and would have the surgery again in the aseptic loosening group as compared to the instability group. Revision to a higher level of constraint did not improve knee function irrespective of the primary indication for surgery. CONCLUSION: This study has found that revision for instability, irrespective of choice of new device, was met with significantly poorer functional outcome. The level of constraint did not influence functional outcome. LEVEL OF EVIDENCE: II.

AIMS: This study uses prospective registry data to compare early patient outcomes following arthroscopic repair or debridement of the acetabular labrum. METHODS: Data on adult patients who underwent arthroscopic labral debridement or repair between 1 January 2012 and 31 July 2019 were extracted from the UK Non-Arthroplasty Hip Registry. Patients who underwent microfracture, osteophyte excision, or a concurrent extra-articular procedure were excluded. The EuroQol five-dimension (EQ-5D) and International Hip Outcome Tool 12 (iHOT-12) questionnaires were collected preoperatively and at six and 12 months post-operatively. Due to concerns over differential questionnaire non-response between the two groups, a combination of random sampling, propensity score matching, and pooled multivariable linear regression models were employed to compare iHOT-12 improvement. RESULTS: A total of 2,025 labral debridements (55%) and 1,659 labral repairs (45%) were identified. Both groups saw significant (p < 0.001) EQ-5D and iHOT-12 gain compared to preoperative scores at 12 months (iHOT-12 improvement: labral repair = +28.7 (95% confidence interval (CI) 26.4 to 30.9), labral debridement = +24.7 (95% CI 22.5 to 27.0)), however there was no significant difference between procedures after multivariable modelling. Overall, 66% of cases achieved the minimum clinically important difference (MCID) and 48% achieved substantial clinical benefit at 12 months. CONCLUSION: Both labral procedures were successful in significantly improving early functional outcome following hip arthroscopy, regardless of age or sex. Labral repair was associated with superior outcomes in univariable analysis, however there was no significant superiority demonstrated in the multivariable model.
