Síndrome de fricción femoroacetabular: tratamiento artroscópico. Resultados a mediano plazo, complicaciones y fallas
Abstract
Introduction: Hip arthroscopy success for treatment of Femoro-Acetabular Impingement (FAI) has been well reported over the past decade.
The indications of this procedure has increased over the past years, as well as complications. The purpose of this study was to assess of clinical-radiological outcomes of hip arthroscopy in adults over 50 years old with FAI, and their complications.
Method: We evaluated patients with a minimum of 3-years follow up. The presence of Pincer and/or CAM deformity was registered by analyzing anteroposterior and lateral x-rays. Articular and chondral damage severity was assessed with Tönnis and Outerbridge classifications respectively.
Objective analysis was performed using Harris Hip Score (HHS) and Hip Outcome Score (HOS). Subjective evaluation was made using Visual Analogue Pain Scale (VAS).
Results: Our study included 114 patients with 56 (49%) and 58(51%) females with a mean of 42,5 years. We observed significant increase in HHS after surgery (71,06 ± 5,68 vs 87,11 ± 5,89 ; p<0,05). VAS demonstrated a statistically significant decrease (6,55 ± 1,27 vs 1,84±1,42; p<0,05). HOS score yielded values of 91% for daily living activities and 87,8% for sports. We observed 3 (2,64%) patients that required conversion to total hip arthroplasty.
Conclusion: Hip Arthroscopy is a very effective tool as joint preservation technique, being able to achieve rates up to 90%, both for daily living activities and sports, after surgery.
