Tratamiento artroscópico del síndrome de fricción femoroacetabular en pacientes con displasia limítrofe. Estudio comparativo
Abstract
Introduction: arthroscopic treatment of femoral-acetabular impingement syndrome in patients with hip dysplasia is controversial. There are some reports that observed an increased failure rate in this type of patients. More recent studies described good patients clinical and functional outcomes, comparable with patients with a normal acetabular coverage. The purpose of this study was to assess functional and clinical outcomes of arthroscopic treatment of FAI in two cohorts: patients with Borderline Dysplasia and patients with a normal lateral center-edge angle.
Materials and methods: we assessed patients reported outcomes of two groups of patients: group 1 that consisted in patients with Borderline Dysplasia and group 2, with patients with a normal lateral center-edge angle. The minimum follow-up required was three years.
Results: there were no statistically significant differences regarding Harris Hip Score and Visual Analogue Scale of Pain respectively (87.0 ± 5.3 versus 85.8 ± 3.6; p = 0.200 y 1.5 ± 0.6 versus 1.3 ± 0.5; p = 0.07) after surgery between both groups. We didn’t observe differences regarding Daily Living Activities (91.8 ± 6,6 versus 93.2 ± 5.9; p = 0.28) or Sports of Hip Outcome Score (85.1 ± 7.7 ± 8.3 versus 88.3 ± 11.9; p = 0.19).
Conclusion: arthroscopic treatment of FAI syndrome in patients with borderline dysplasia, achieves good clinical and functional outcomes, comparable with patients with a normal lateral center-edge angle.
