Abstract:
Objective:To evaluate the clinical outcomes of patients with borderline developmental dysplasia of the hip (BDDH) and cam-type femoroacetabular impingement syndrome (FAIS) after hip arthroscopy.Methods:Data were retrospectively reviewed for patients with BDDH and cam-type FAIS who underwent hip arthroscopy surgery from June 2017 to December 2019. A total of 32 patients were enrolled, with a mean age of 36.13±8.67 years (range, 20-50 years), including 15 males and 17 females. The preoperative lateral center-edge angle was 22.3°±1.6° (range 20.1°-24.7°), while the preoperative α angle was 64.1°±4.6° (range, 56.0°-69.8°). All patients were treated with arthroscopic limited acetabular plasty, labral repair, femoral osteoplasty, and capsular plication after excluding from external hip diseases by ultrasound-guided hip blocking test. The visual analogue scale (VAS), modified Harris Hip Scores (mHHS) and International Hip Outcome Tool-12 (iHOT-12) scores were used to evaluate the clinical effects.Results:All patients were followed up, and the mean follow-up time was 2.5±0.8 years (range, 2.0-4.7 years). The VAS score decreased from 6.07±1.56 to 1.96±0.92 at 1 year and to 1.86±1.01 at 2 years after operation ( F=112.64, P<0.001); the mHHS score increased from 53.87±13.04 to 86.12±8.64 at 1 year and to 88.71±8.15 at 2 years after operation ( F=101.70, P<0.001); the iHOT-12 score was improved from 40.00±7.33 to 76.27±9.50 at 1 year and to 78.67±10.31 at 2 years after operation ( F=134.91, P<0.001). The α angle improved to 40.27°±4.52° (range, 34.8°-49.7°) with significant difference ( t=9.24, P<0.001). Conclusion:Hip arthroscopy can achieve satisfied short-term outcomes in treating BDDH and cam-type FAIS with few complications and less trauma.
