“…Substantial inter-and intraobserver agreement has been reported for the anterior impingement test [24], ROM [15,25,50], and the Merle d'Aubigné-Postel score [19]. At followup, additional hip scores were assessed including the WOMAC [4], the Harris hip score (HHS) [14], the SF-12 Physical and Mental Component Scales [12,48], and the University of California Los Angeles (UCLA) activity score [51].…”

Background Patients with femoroacetabular impingement (FAI) often develop pain, impaired function, and progression of osteoarthritis (OA); this is commonly treated using surgical hip dislocation, femoral neck and acetabular rim osteoplasty, and labral reattachment. However, results with these approaches, in particular risk factors for OA progression and conversion to THA, have varied. Questions/purposes We asked if patients undergoing surgical hip dislocation with labral reattachment to treat FAI experienced (1) improved hip pain and function; and (2) prevention of OA progression; we then determined (3) the survival of the hip at 5-year followup with the end points defined as the need for conversion to THA, progression of OA by at least one Tönnis grade, and/or a Merle d'Aubigné-Postel score less than 15; and calculated (4) factors predicting these end points. Methods Between July 2001 and March 2003, we performed 146 of these procedures in 121 patients. After excluding 35 patients (37 hips) who had prior open surgery and 11 patients (12 hips) who had a diagnosis of Perthes disease, this study evaluated the 75 patients (97 hips, 66% of the procedures we performed during that time) who had a mean followup of 6 years (range, 5-7 years). We used the anterior impingement test to assess pain, the Merle d'Aubigné-Postel score to assess function, and the Tönnis grade to assess OA. Survival and predictive factors were calculated using the method of Kaplan and Meier and Cox regression, respectively. Results The proportion of patients with anterior impingement decreased from 95% to 17% (p \ 0.001); the Merle d'Aubigné-Postel score improved from a mean of 15 to 17 (p \ 0.001). Seven hips (7%) showed progression of OA and another seven hips (7%) converted to THA Survival free from any end point (THA, progression of OA, or a Merle d'Aubigné-Postel \ 15) of well-functioning joints at 5 years was 91%; and excessive acetabular rim trimming, preoperative OA, increased age at operation, and weight were predictive factors for the end points. Conclusions At 5-year followup, 91% of patients with FAI treated with surgical hip dislocation, osteoplasty, and labral reattachment showed no THA, progression of OA, or an insufficient clinical result, but excessive acetabular trimming, OA, increased age, and weight were associated with early failure. To prevent early deterioration of the joint, excessive rim trimming or trimming of borderline dysplastic hips has to be avoided.

“…Clinical evaluations included a physical examination, Harris hip score [17], WOMAC score [2], and administration of a questionnaire (Appendix 1) on functional topics related to THA such as job choice, pregnancy, and childbirth. Patient activity levels were rated using a modified version of the UCLA Activity Level Scale [40] and Devane activity level scale [6]. A questionnaire that included items regarding any noise during daily activity (the presence of noise; the nature, time of onset, and frequency of the noise and activities associated with the noise; awareness of the noise by other people; intensity of the noise with time; associated pain; and effect of the noise on the quality of life) was completed.…”

Background THA in patients younger than 30 years presents challenges because of uncertainties regarding the long-term survivorship of prostheses. Alumina-on-alumina bearings, which exhibit little long-term wear, may be a reasonable option but the long-term survivorship is unknown. Questions/Purposes We determined (1) the survival rate of alumina-on-alumina bearings in patients younger than 30 years after a 10-year followup, (2) the incidence of audible hip clicking and squeaking, (3) radiographic evidence of osteolysis, and (4) the effects on pregnancy, childbirth, and career choice. Methods We retrospectively reviewed 62 patients who had 75 THAs with alumina-on-alumina bearings followed more than 10 years (average, 11.5; range, 10-13.5 years). Mean patient age at the time of surgery was 24 years (range, 18-30 years). All operations were performed using the same cementless implant at a single center. We determined survival, presence of osteolysis, and function (Harris hip score, WOMAC).

“…Clinical evaluation included preoperative Knee Society scores [14] and, at final followup, the need for reoperation, the Knee Society score, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) [1], SF-36 general health questionnaire, and activity level via the UCLA [26] and Tegner [25] scales. All patients were encouraged to return for routine clinical and radiographic followup.…”
