“…Among patients with labral tears, the locations were anterior (15), lateral (12), anterolateral (7), and posterior (6). Among patients with chondral damage, there were one Grade II, 14 Grade III, and 12 Grade IV lesions using the Outerbridge classification [21]. The duration of symptoms ranged from 1 to 156 months, with an average of 21 months.…”

Arthroscopic surgery of the hip is a wellestablished technique with numerous recognized indications. Despite the well-accepted nature of this procedure, there have been no outcomes studies with extended followup. We investigated the response to hip arthroscopy in a consecutive series of patients with 10 years followup. Since 1993, all patients undergoing hip arthroscopy have been assessed prospectively with a modified Harris hip score preoperatively and then postoperatively at 3, 12, 24, 60, and 120 months. A cohort of 50 patients (52 hips) was identified who had achieved 10-year followup and represent the substance of this study. There was 100% followup. The average age of the patients was 38 years (range, 14-84 years), with 27 males and 23 females. The median improvement was 25 points (preoperative, 56 points; postoperative, 81 points). Fourteen patients were converted to THA and two died. Four patients underwent repeat arthroscopy. There were two complications in one patient.

“…Noguchi et al [38] in their arthroscopic evaluation of the articular cartilage of dysplastic hips reported that even at the early stage radiographically, severe degeneration of articular cartilage with subchondral exposure could be present. Yasunaga et al [62] found that even when postoperative joint congruency was classified as good in their criteria, there was the possibility of OA progression if the intraoperative arthroscopic evaluation is Outerbridge's Grade 4 [44]. Cunningham et al [7] reported a Level II prognostic study.…”

Background Hip dysplasia is the most common cause of secondary osteoarthritis (OA). Periacetabular osteotomy (PAO) or rotational acetabular osteotomy (RAO) has been used as a joint-preserving procedure. However, the patient selection criteria are not clearly defined. Questions/purposes Based on a systematic review, we identified reported patient selection criteria for PAO or RAO. Methods We performed a systematic review of RAO and 18 studies met our inclusion criteria. For the PAO, the systemic review performed by Clohisy et al. was used. Where Are We Now? For patients with symptomatic hip dysplasia, lateral center-edge angle less than 10°to 30°, radiographic pre-or early OA, mean age at the time of surgery of 18 to 45 years, and improvement in joint congruency on AP radiograph with hip abduction, radiographic deformity correction consistently improved hip function in all studies. Radiographic OA progression was noted in 5% to 33% at 3.2 to 20 years postoperatively. Clinical score and prevention of radiographic OA progression of patients 50 years or older or with advanced stage were worse in younger patients or those with early stage. Where Do We Need to Go? The key challenges are (1) preoperative evaluation of articular cartilage; (2) indication for older patients; (3) prevention of secondary femoroacetabular impingement; and (4) intraarticular treatment combined with PAO or RAO. How Do We Get There? Future prospective, longitudinal cohort studies need to determine optimal patient selection criteria, risk factors for clinical failure, optimal deformity correction parameters, and the role of adjunctive surgical procedures.

“…During surgery, the distal lateral femoral condyle of all knees was macroscopically analyzed using the Outerbridge grading scale [36]. Knees with an Outerbridge Grade 2 or more were excluded from the current study because they were not considered potential candidates for UKA, leaving 72 knees (37 left knees and 35 right knees) in 63 patients (29 men and 34 women) included in the study.…”
