Artroscopía de cadera para síndrome de fricción femoroacetabular. Reportes funcionales a diez años

Abstract

Background and objectives: the aim of this study is to evaluate the functional outcomes of patients treated with hip arthroscopy for femoroacetabular impingement syndrome with a follow-up period of more than ten years.

Materials and methods: a retrospective study of fifty-eight patients (sixty-one hips) who met our inclusion criteria was carried out from a series of eighty-two patients who underwent hip arthroscopy from April 2008 to December 2013. Only patients with a follow-up of ten years or more were included. We compared the functional results obtained in the long term with the results of these, prior to surgery. The mean follow-up time was 148.5 months (range, 120-177 months). A total of thirty-two male and twenty-six female patients were evaluated, and the mean age of surgery was 33.2 ± 7.7 (control 43.2 ± 11.1 years). Four functional scales were used: modified Harris Hip Score (mHHS), Hip outcome Score-Activities of Daily Life (HOS-ADL), Hip Outcome Score Sport (HOS-SSS) and Visual Analog Pain Scale (VAS).

Results: the VAS score had a statistically significant decrease from 7.9 points to 2.2 points on average, p <0.0001. The HHSm had a statistically significant increase from 47.9 in the preoperative period to 72.66 in the postoperative period, p <0.0001. The HOS-ADL and HOS-SSS scales had a statistically significant increase from 60.9 and 46.7 to 90.45 and 86.1 points, respectively, p <0.0001. Only two cases were converted to total hip replacement at three and five years (2.43%).

Conclusions: patients treated with hip arthroscopy for acetabular femoroacetabular impingement syndrome with labral debridement or repair, acetabuloplasty, and osteoplasty of Cam's deformity show very good long-term functional outcomes associated with a low conversion rate to total hip replacement at ten or more years.
