PURPOSE: To investigate the outcomes of @entity2249 in @entity1 with @entity4039 ( @entity4039 )-related impingement. METHODS: We retrospectively reviewed 37 consecutive @entity1 (40 hips; 19 male and 18 female @entity1 ; age range, 10 to 19  years) with @entity4039 who underwent hip arthroscopy for femoral neck osteoplasty over a 4-year period. Six hips were excluded because of the severity of the slip or conversion to an open procedure. The preoperative and postoperative slip angle, alpha angle, and internal rotation in flexion were compared. @entity1 were evaluated for @entity158 , functional limitations, and @entity717 ( @entity717 ) at each follow-up visit. The mean follow-up period was 22  months (range, 12 to 56  months). RESULTS: We analyzed the results of 34 hips. Adequate distraction could not be obtained initially in 7 hips. The labral and acetabular cartilage damage appeared to be from crushing and abrasion from the bony prominence of the neck. The goals of complete @entity158 relief and correction of @entity717 were achieved in 88% of the hips. @entity717 and @entity158 persisted in 2 hips, and 2 @entity1 had residual @entity158 despite good motion. There was a statistically significant improvement in alpha angle (from 88.22   and 56.91  , P < .0001) and internal rotation in flexion (from  -21.53   to 10.28  , P < .0001) with intervention. CONCLUSIONS: @entity2249 is effective in decreasing @entity158 , the alpha angle, and @entity717 in mild to moderate @entity4039 . @entity5845 , scarring from previous surgery, and the presence of screws in the anterior neck presented challenges to the arthroscopic technique. LEVEL OF EVIDENCE: Level IV, therapeutic case series.
