Objective: This study aimed to evaluate the functional outcomes of arthroscopic debridement of labral tears retrospectively.

Methods: Between April 2001 and September 2006, 17 patients who underwent arthroscopic debridement were analyzed. Functional outcomes of the patients were assessed using modified Harris hip score (MHHS). Mann-Whitney U and Wilcoxon tests were used to evaluate the data. P<0.05 was considered statistically significant.

Results: In total, 70.5% of the patients had developmental dysplasia of hip (DDH) at the time. Carti-lage damage was detected in 88% of the patients, and both acetabular and femoral compartments were involved in 35% of them. Postoperative MHHS increased in all patients after hip arthroscopy. However, in patients with DDH, MHHS was significantly lower than that in non-DDH patients (p<0.05). Labral tears often found to be associated with developmental dysplasia of the hip (DDH).

Conclusion: Patients with DDH and chondral damage in both compartments may benefit less than the patients with unicompartmental chondral damage from arthroscopic debridement.
