Editorial Commentary: With Properly Indicated and Performed Surgery, We Can (Hopefully) Prevent Osteoarthritis in Patients With Hip Femoroacetabular Impingement.

Surgical treatment of femoroacetabular impingement (FAI) syndrome has been proven to be tremendously successful, outperforming the best conservative care and physical therapy in several prospective multicenter randomized controlled trials. The durability of this operation over time is less commonly reported on. We do know that FAI is associated with the development of hip osteoarthritis, and this is well established. We also know that surgical FAI treatment results in good short-term return to function/sport and improvements in patient-reported outcomes. We do not yet know if we are able to alter the natural history of FAI and prevent or delay conversion to total hip arthroplasty in this population.

Implementation of the Good Life with osteoArthritis in Denmark (GLA:D) Program across Canada for the Management of Hip and Knee Osteoarthritis.

Good Life with osteoArthritis in Denmark (GLA:D®) is a program for the management of patients with hip and knee osteoarthritis (OA). Adapted for the Canadian population, the GLA:DTM Canada program implements evidence-based strategies to support the prevention, early diagnosis and effective management of hip and knee OA. GLA:D assists local communities in implementing OA strategies across the spectrum of disease severity. An integral part of this program is a national quality and outcomes registry, which includes data concerning participant characteristics and both patient-reported and functional outcomes. This registry helps healthcare providers and healthcare decision makers ensure that individuals with OA receive effective, high-quality care through the GLA:D Canada program.

To what extent is severe osteoarthritis preventable? Occupational and non-occupational risk factors for knee and hip osteoarthritis.

OBJECTIVES: To explore the relative contribution of cumulative physical workload, sociodemographic and lifestyle factors, as well as prior injury to hospitalization due to knee and hip OA. METHODS: We examined a nationally representative sample of persons aged 30-59 years, who participated in a comprehensive health examination (the Health 2000 Study). A total of 4642 participants were followed from mid-2000 to end-2015 for the first hospitalization due to knee or hip OA using the National Hospital Discharge Register. We examined the association of possible risk factors with the outcome using a competing risk regression model (death was treated as competing risk) and calculated population attributable fractions for statistically significant risk factors. RESULTS: Baseline age and BMI as well as injury were associated with the risk of first hospitalization due to knee and hip OA. Composite cumulative workload was associated with a dose-response pattern with hospitalizations due to knee OA and with hospitalizations due to hip OA at a younger age only. Altogether, prior injury, high BMI and intermediate to high composite cumulative workload accounted for 70% of hospitalizations due to knee OA. High BMI alone accounted for 61% and prior injury only for 6% of hospitalizations due to hip OA. CONCLUSION: Our results suggest that overweight/obesity, prior injury and cumulative physical workload are the most important modifiable risk factors that need to be targeted in the prevention of knee OA leading to hospitalization. A substantial proportion of hospitalizations due to hip OA can be reduced by controlling excess body weight.

The two-year incidence of hip osteoarthritis after arthroscopic hip surgery for femoroacetabular impingement syndrome.

BACKGROUND: One of the reported goals of hip preservation surgery is to prevent or delay the onset of osteoarthritis. This includes arthroscopic surgery to manage Femoroacetabular Impingement (FAI) Syndrome. The purpose of this study was to describe the prevalence of clinically-diagnosed hip OA within 2 years after hip arthroscopy for FAI syndrome, and 2) determine which variables predict a clinical diagnosis of OA after arthroscopy. METHODS: Observational analysis of patients undergoing hip arthroscopy between 2004 and 2013, utilizing the Military Health System Data Repository. Individuals with prior cases of osteoarthritis were excluded. Presence of osteoarthritis was based on diagnostic codes rendered by a medical provider in patient medical records. Adjusted odds ratios (95% CI) for an osteoarthritis diagnosis were reported for relevant clinical and demographic variables. RESULTS: Of 1870 participants in this young cohort (mean age 32.2 years), 21.9% (N = 409) had a postoperative clinical diagnosis of hip osteoarthritis within 2 years. The 3 significant predictors in the final model were older age (OR = 1.04; 95%CI = 1.02, 1.05), male sex (OR = 1.31; 95%CI = 1.04, 1.65), and having undergone an additional hip surgery (OR = 2.33; 95% CI = 1.72, 3.16). Military status and post-surgical complications were not risk factors. CONCLUSION: A clinical diagnosis of hip osteoarthritis was found in approximately 22% of young patients undergoing hip arthroscopy in as little as 2 years. These rates may differ when using alternate criteria to define OA, such as radiographs, and likely underestimate the prevalence. A more comprehensive approach, considering various criteria to detect OA will likely be necessary to accurately identify the true rates. Females were at lower risk, while increasing age and multiple surgeries increased the risk for an OA diagnosis. OA onset still occurs after "hip preservation" surgery in a substantial number of individuals within 2 years. This should be considered when estimating rates of disease prevention after surgery. Prospective trials with sound methodology are needed to determine accurate rates and robust predictors of osteoarthritis onset after hip preservation surgery.

The Natural History of Lower Extremity Malalignment.

BACKGROUND: Lower extremity malalignment is a common problem presented to pediatric orthopaedists. Risk for early arthritis is often a concern among parents seeking advice and treatment. We seek to review previous research with regard to the natural history of malalignment. METHODS: A search of available literature on PubMed was constructed to capture articles covering the natural history of malalignment, secondary to childhood fracture as well as congenital and acquired pediatric deformity. In order to remain strictly relevant to pediatrics, articles reviewing deformities acquired in adulthood were not referenced. Biomechanical data and animal studies were included when deemed appropriate. RESULTS: High-quality data with regard to long-term risk of arthritis due to malalignment is lacking. Through a combination of biomechanical data, animal models, and a small body of longitudinal clinical data, it is clear that some patients with malalignment progress to early arthritic change. Unfortunately, detailed risk factors of who is at high risk versus low risk remains difficult to determine. CONCLUSIONS: Treatment of minor lower extremity malalignment is not supported by the current orthopaedic literature. Treatment plans should focus on the presence of symptoms, and in asymptomatic but severe cases. Even in more severe cases, strong evidence to support prophylactic realignment is not available. Evidence to suggest that preventative realignment is superior to intervention at the time of symptom onset does not exist.

The Effects of Hip Mobilizations on Patient Outcomes: A Critically Appraised Topic.

Clinical Scenario: Hip osteoarthritis currently affects up to 28% of the population, and the number of affected Americans is expected to rise as the American population increases and ages. Limited hip range of motion (ROM) has been identified as a predisposing factor to hip osteoarthritis and limited patient function. Clinicians often apply therapy techniques, such as stretching and strengthening exercises, to improve hip ROM. Although traditional therapy has been recommended to improve hip ROM, the efficiency of the treatments within the literature is questionable due to lack of high-quality studies. More recently, clinicians have begun to utilize joint mobilization and the Mulligan Concept mobilization with movement techniques to increase ROM at the hip; however, there is a paucity of research on the lasting effects of mobilizations. Given the difficulties in improving ROM immediately (within a single treatment) and with long-lasting results (over the course of months), it is imperative to examine the evidence for the effectiveness of traditional therapy techniques and more novel manual therapy techniques. Focused Clinical Question: Is there evidence to suggest manual mobilizations techniques at the hip are effective at treating hip ROM limitations? Summary of Clinical Findings: 5 Randomized Controlled Studies, improved patient function and ROM with the Mulligan concept, high velocity low amplitude improved. Clinical Bottom Line: We found moderate evidence to suggest favorable outcomes following the use of hip mobilizations aimed at improving hip ROM and patient function. Strength of Recommendation: Strength of the studies identified are 1B.

Single Versus Combined Procedures for Severely Involved Legg-Calvé-Perthes Disease.

BACKGROUND: The concept of containment as an effective approach to reduce the risk of femoral head deformity has been questioned because modest results have been achieved after nonoperative and operative treatments for severely involved Legg-Calvé-Perthes disease. Several reports have shown the limited effectiveness of some conventional single procedures. However, there is limited data on the effectiveness of combined procedures. METHODS: The surgical group comprised 77 patients (mean age 8.3 y) and involved 79 hips. The average follow-up term was 9.5 years. Sixty-five patients were unilaterally involved and 12 patients were bilaterally involved (although 10 of the latter patients only received surgery on 1 hip). Among patients, 28 hips were classified as Herring class B/C border (>8 y old) and 51 hips were Herring class C. The 79 hips were divided into 2 treatment groups for further analysis: group 1, single procedures (femoral varus osteotomy) (n=47); group 2, combined procedures [femoral varus osteotomy+Dega (Pemberton) osteotomy] (n=32). RESULTS: Using Stulberg classification I and II (acceptable outcome), the final outcome was statistically significant for group 2 (21 hips, 65.6%) compared with group 1 (18 hips, 38.3%) (P=0.031). The average remodeling efficacy, defined as the change in caput index between preoperation and postoperation, was better in group 2 (12.7%) than in group 1 (3.9%) (P=0.005). The acetabulum-head index and α-angle were also statistically significant in group 2 than in group 1 at the last follow-up. Clinical evaluations were statistically significant in group 2 compared with group 1. CONCLUSIONS: Both clinically and radiologically, the combined procedure group demonstrated significantly better outcomes with accelerated remodeling in both the severely affected femoral heads and the acetabula compared with the single procedure group. With this procedure, we anticipate the increased likelihood of preventing or delaying coxarthroses in adulthood. LEVEL OF EVIDENCE: Level III-therapeutic study.

Delays in diagnosis are associated with poorer outcomes in adult hip dysplasia.

Background and Aims Developmental dysplasia of the hip is a common cause of osteoarthritis. Periacetabular osteotomy can restore femoral head coverage; however, it is reserved for patients with minimal articular degeneration. We examined the relationship between delays in diagnosis and outcomes. Methods We identified patients presenting to a hip specialist with a new diagnosis of hip dysplasia. The time taken between patients presenting to their general practitioner and attending the young adult hip clinic was established. Patients were stratified into Early, Moderate and Late Referral groups. Hip and SF-12 questionnaires were completed. Radiographs were graded according to the Tönnis classification system and the outcome following hip specialist review documented. Results Fifty-one patients were identified. Mean time from attending a general practitioner to review at the young adult hip clinic was 40.4 months. Lower hip and SF-12 scores, and higher radiological osteoarthritis grades were found in the Moderate and Late Referral groups. A higher proportion of the Moderate and Late Referral group underwent total hip arthroplasty rather than periacetabular osteotomy. Conclusion Delays in referring a patient to a hip specialist are associated with poorer outcomes. We propose pelvic radiographs are requested early by general practitioners to allow prompt diagnosis and referral to a hip specialist.

Preoperative prognosis score is a useful tool regarding eccentric rotational acetabular osteotomy in patients with acetabular dysplasia.

BACKGROUND: It is unknown how possible preoperative factors influence the postoperative outcome of eccentric rotational acetabular osteotomy (ERAO). We aimed to determine these factors and to develop a scoring system for predicting the prognosis after ERAO in patients with symptomatic hip dysplasia. PATIENTS: We included 700 patients (54 men, 646 women) who underwent ERAO during September 1989 to March 2013. The patients' clinical background, preoperative clinical findings, and preoperative imaging findings were examined retrospectively. Univariate and multivariate Cox regression were performed using the time from the day of surgery to a Harris hip score (HHS) <80 as an endpoint. A failure score was defined to predict the prognosis for an HHS <80, and its predictive capacity was assessed. RESULTS: Ninety patients had an HHS <80. Forty-two patients underwent conversion to total hip arthroplasty (THA) after their HHS decreased to <80. Five factors were identified in relation to an HHS <80: a history of congenital dislocation of the hip, joint congruity, body mass index, the preoperative minimum joint space width, and the preoperative abduction range of motion. We estimated the weight of each factor using the results of multivariate Cox regression, and the outcome prediction scoring was obtained (0-17 points). For three groups of patients (total points of each factors: 0-5, 6-9, and ≥10 points), the Kaplan-Meier event-free survival rates at 15 years postoperatively for an HHS <80 were 97%, 81%, and 55%, respectively; the survival rates for THA conversion using this prediction scoring were 99%, 96%, and 85%, respectively. CONCLUSIONS: Five preoperative factors can easily and clearly predict the prognosis following ERAO. The prognosis score may be a useful tool when making a decision regarding operative treatments in adult patients with acetabular dysplasia.

[Bernese periacetabular osteotomy. : Indications, technique and results 30 years after the first description]. / Periazetabuläre Osteotomie nach Ganz : Indikationen, Technik und Ergebnisse 30 Jahre nach Erstbeschreibung.

The Bernese periacetabular osteotomy (PAO) is a surgical technique for the treatment of (1) hip dysplasia and (2) femoroacetabular impingement due to acetabular retroversion. The aim of the surgery is to prevent secondary osteoarthritis by improvement of the hip biomechanics. In contrast to other pelvic osteotomies, the posterior column remains intact with this technique. This improves the inherent stability of the acetabular fragment and thereby facilitates postoperative rehabilitation. The birth canal remains unchanged. Through a shortened ilioinguinal incision, four osteotomies and one controlled fracture around the acetabulum are performed. The direction of acetabular reorientation differs for both indications while the sequence of the osteotomies remains the same. This surgical approach allows for a concomitant osteochondroplasty in the case of an aspherical femoral head-neck junction. The complication rate is relatively low despite the complexity of the procedure. The key point for a successful long term outcome is an optimal reorientation of the acetabulum for both indications. With an optimal reorientation and a spherical femoral head, the cumulative survivorship of the hip after 10 years is 80-90 %. For the very first 75 patients, the cumulative 20-year survivorship was 60 %. The preliminary evaluation of the same series at a 30-year follow-up still showed a survivorship of approximately 30 %. The PAO has become the standard procedure for the surgical therapy of hip dysplasia in adolescents and adults.

Corticosteroids and low bone mineral density affect hip cartilage in systemic lupus erythematosus patients: Quantitative T2 mapping.

BACKGROUND: The purpose of this diagnostic study was to quantify the effect of high-dose corticosteroid treatment on hip joint cartilage degeneration in patients with systemic lupus erythematosus (SLE), with and without osteonecrosis, using magnetic resonance imaging (MRI). METHODS: T2 mapping, with a 3.0 Tesla Discovery MR750 (GE Healthcare) MRI scanner, was performed in 12 volunteers without hip pathology (control group, 12 hips), in 11 patients with SLE without osteonecrosis, who were receiving corticosteroid therapy (corticosteroid-ON group, 17 hips), and in 15 patients with SLE receiving corticosteroids, who had noncollapsed and asymptomatic osteonecrosis (corticosteroid+ON group, 26 hips). The distribution of T2 values in the femoral head and acetabular cartilage were compared among the three groups. Step-wise multiple regression analysis was performed to determine the prognostic factors for T2 values indicative of femoral head cartilage degeneration. RESULTS: Mean T2 values of femoral head cartilage were significantly higher in the corticosteroid-ON (40.3 ms) and corticosteroid+ON (35.2 ms) groups than in the control group (30.1 ms, P = 0.001). T2 values of acetabular cartilage were significantly higher in the corticosteroid-ON group (41.8 ms) versus the control (33.4 ms) and the corticosteroid+ON groups (37.0 ms; P = 0.001). Low bone mineral density was a significant prognostic factor for high T2 values of cartilage at the femoral head in patients treated with corticosteroids, regardless of whether they had osteonecrosis. CONCLUSION: T2 mapping suggests that corticosteroid therapy and osteoporosis are independent risk factors for cartilage degeneration at the femoral head in patients with SLE.

Osteoarthritis prevalence and modifiable factors: a population study.

BACKGROUND: This study's objectives were to investigate the prevalence of self-reported knee and hip osteoarthritis (OA) stratified by age and sex and to examine the association of modifiable factors with knee and hip OA prevalence. The study was conducted using randomly sampled data gathered from four communities in the province of Alberta, Canada. METHODS: A large adult population sample (N = 4733) of individuals ≥18 years were selected. Health-related information was collected through telephone interviews and community measurement clinics for which a sub-sample (N = 1808) attended. Participants self-reported OA during telephone interviews. Clinic interviews further assessed if the diagnosis was made by a health care professional. Statistical analyses compared prevalence of OA between sexes and across age categories. Associations between modifiable factors for OA and the prevalence of knee and hip OA were assessed using binary logistic regression modelling. RESULTS: Overall prevalence of self-reported OA in the total sample was 14.8 %, where 10.5 % of individuals reported having knee OA and 8.5 % reported having hip OA. Differences in prevalence were found for males and females across age categories for both knee and hip OA. In terms of modifiable factors, being obese (BMI >30 kg/m2) was significantly associated with the prevalence of knee (OR: 4.37; 95 % CI: 2.08,9.20) and hip (OR: 2.52; 95 % CI: 1.17,5.43) OA. Individuals who stand or walk a lot, but do not carry or lift things during their occupational activities were 2.0 times less likely to have hip OA (OR: 0.50; 95 % CI: 0.26,0.96). Individuals who usually lift or carry light loads or have to climb stairs or hills were 2.2 times less likely to have hip OA (OR: 0.45; 95 % CI: 0.21,0.95). The odds of having hip OA were 1.9 times lower in individuals consuming recommended or higher vitamin C intake (OR: 0.52; 95 % CI: 0.29,0.96). Significant differences in prevalence were found for both males and females across age categories. CONCLUSION: The prevalence of knee and hip OA obtained in this study is comparable to other studies. Females have greater knee OA prevalence and a greater proportion of women have mobility limitations as well as hip and knee pain; it is important to target this sub-group.

Femoroacetabular impingement surgery: are we moving too fast and too far beyond the evidence?

Femoroacetabuler impingement (FAI) is becoming increasingly recognised as a potential pathological entity for individuals with hip pain. Surgery described to correct FAI has risen exponentially in the past 10 years with the use of hip arthroscopy. Unfortunately, the strength of evidence supporting both the examination and treatment of FAI does not appear to accommodate this exponential growth. In fact, the direction currently taken for FAI is similar to previously described paths of other orthopaedic and sports medicine pathologies (eg, shoulder impingement, knee meniscus tear) for which we have learned valuable lessons. The time has come for improved terminology, study design, and focus on delineation of successful treatment variables in the interest of those individuals with clinical indications of FAI so that we can appropriately address their needs.

Two cases of avascular necrosis after prophylactic pinning of the asymptomatic, contralateral femoral head for slipped capital femoral epiphysis: case report and review of the literature.

BACKGROUND: In a child with a unilateral slipped capital femoral epiphysis (SCFE), the treatment of the radiographically normal, asymptomatic contralateral hip remains controversial. The risks of a subsequent slip have to be measured against the risks involved with an additional surgical procedure. Proponents of prophylactic pinning believe that fixation with a single cannulated screw is a safe method to prevent secondary arthrosis from a missed minor slip. Others argue that in most cases it is an unnecessary procedure and with careful follow-up, any issues with the asymptomatic, normal hip can be identified early and addressed. METHODS: We retrospectively look at 2 cases where avascular necrosis (AVN) developed in the prophylactically pinned asymptomatic and radiographically normal hip in the setting of an identified SCFE on the contralateral hip. RESULTS: Two cases of AVN developed in the prophylactically pinned hips within 8 months of the initial pinning procedure. CONCLUSIONS: This case report demonstrates that prophylactic pinning of an asymptomatic, radiographically normal hip in the setting of a SCFE on the contralateral side is not a benign procedure and is one that has potential for significant complications. The risk of AVN in the prophylactically pinned hip needs to be taken into careful consideration as this risk can have devastating consequences to the patient. LEVEL OF EVIDENCE: Level IV.

Ultrasound and fluoroscopy are unnecessary for injections into the arthritic hip.

PURPOSE: We investigated the effectiveness of non-image-guided hip injections. METHODS: We retrospectively evaluated 369 intra-articular hip injections in 331 patients using anatomical landmarks. The percentage and duration of pain relief was documented. Hip injections were grouped in responders and nonresponders (50 % maximum pain relief as a cut off). RESULTS: In 82% (n = 304) of hip injections, patients responded positively and experienced >50 % pain relief. Nonresponders had a significantly higher body mass index (p = 0.007). CONCLUSIONS: Hip injections using anatomical landmarks are an effective treatment option for patients with osteoarthritis of the hip.

Common questions about developmental dysplasia of the hip.

Developmental dysplasia of the hip is a common musculoskeletal condition in newborns. Infants with developmental dysplasia of the hip, whether treated or untreated, have a higher incidence of early-onset hip osteoarthritis in adulthood. Evidence to support universal screening by physical examination or ultrasonography is limited and often conflicting. The U.S. Preventive Services Task Force found insufficient evidence that screening for developmental dysplasia of the hip prevents adverse outcomes. Physical examination screening is recommended by the American Academy of Pediatrics and the Pediatric Orthopaedic Society of North America. These organizations recommend use of the Ortolani and Barlow maneuvers to screen infants up to three months of age. Several recent studies support starting assessment for limited hip abduction at eight weeks of age, which is the most sensitive test for developmental dysplasia of the hip from this age on. Infants with overtly dislocated or dislocatable hips should be referred to an orthopedist on a priority basis at the time of diagnosis. Infants with equivocal hip examination findings at birth can be reexamined in two weeks. If there is subluxation or dislocation at the follow-up examination, referral should be made at that time. If the examination findings are still equivocal, the infant can undergo ultrasonography of the hips or be reexamined every few weeks through the first six weeks of life. Although equivocal findings commonly resolve spontaneously, infants with persistent equivocal findings of developmental dysplasia of the hip longer than six weeks should be evaluated by an orthopedist. Treatment generally involves flexion-abduction splinting. The benefits of treatment are unclear, and there are risks to treatment, most notably an increased occurrence of avascular necrosis of the femoral head.

[Complications after osteosynthesis of the proximal femur]. / Komplikationen nach Osteosynthese des proximalen Femurs.

BACKGROUND: Fractures of the proximal femur are among the most common fractures of all bones. Currently nearly every trauma surgeon has to be able to treat proximal femur fractures either with osteosynthesis or with a prosthesis. An increase of 200-300 % of fractures of the proximal femur is expected within the next 30 years. In addition an increase of periprosthetic fractures of the proximal and distal femur can be observed. The correct treatment of these complications is a challenging objective for the trauma surgeon. OBJECTIVES: This article provides an overview on complications after osteosynthesis of the proximal femur. It contributes treatment options depending on the implant, the patient specific risk factors and the special problems of postoperative care. METHODS: A selective review of the literature using Pubmed under consideration of experiences gained in the treatment of complications after osteosynthesis of the proximal femur was performed. CONCLUSIONS: Due to the increasing incidence of fractures of the proximal femur on the one hand and complications after operative treatment of these fractures on the other, the trauma surgeon must provide differentiated therapy concepts depending on the individual risk factors of different patients. Moreover, trauma surgeons must know how to treat the potential complications of these procedures.

[Complications after hip osteotomy]. / Komplikationen nach Beckenosteotomien.

Complex deformities of the acetabulum are one of the most common reasons for secondary pelvic osteoarthritis. One option of treatment is osteotomy of the acetabulum close to the joint. The correction of the spatially reduced roof of the femoral head resulting from pelvic dysplasia can minimize the risk of developing secondary osteoarthritis or reduce the progression of an already existing osteoarthritis. The Ganz periacetabular osteotomy (PAO) and Tönnis triple osteotomy procedures are the predominant methods used to correct hip dysplasia in adolescents. Both are complex procedures which bear specific risks and complications, thus requiring very experienced surgeons.

Cam deformity and hip degeneration are common after fixation of a slipped capital femoral epiphysis.

BACKGROUND AND PURPOSE: Slipped capital femoral epiphysis is thought to result in cam deformity and femoroacetabular impingement. We examined: (1) cam-type deformity, (2) labral degeneration, chondrolabral damage, and osteoarthritic development, and (3) the clinical and patient-reported outcome after fixation of slipped capital femoral epiphysis (SCFE). METHODS: We identified 28 patients who were treated with fixation of SCFE from 1991 to 1998. 17 patients with 24 affected hips were willing to participate and were evaluated 10-17 years postoperatively. Median age at surgery was 12 (10-14) years. Clinical examination, WOMAC, SF-36 measuring physical and mental function, a structured interview, radiography, and MRI examination were conducted at follow-up. RESULTS: Median preoperative Southwick angle was 22o (IQR: 12-27). Follow-up radiographs showed cam deformity in 14 of the 24 affected hips and a Tönnis grade>1 in 1 affected hip. MRI showed pathological alpha angles in 15 affected hips, labral degeneration in 13, and chondrolabral damage in 4. Median SF-36 physical score was 54 (IQR: 49-56) and median mental score was 56 (IQR: 54-58). These scores were comparable to those of a Danish population-based cohort of similar age and sex distribution. Median WOMAC score was 100 (IQR: 84-100). INTERPRETATION: In 17 patients (24 affected hips), we found signs of cam deformity in 18 hips and early stages of joint degeneration in 10 hips. Our observations support the emerging consensus that SCFE is a precursor of cam deformity, FAI, and joint degeneration. Neither clinical examination nor SF-36 or WOMAC scores indicated physical compromise.
