Results of Arthroscopic Treatment for Femoroacetabular Impingement

Background. Femoroacetabular impingement (FAI) is one of the most frequent causes hip pain and limited mobility in young middle-aged patients. It a result repeated injury structures, that leads to degenerative changes labrum, cartilage subchondral bone provokes progressive development osteoarthritis.
 Aim study analyze own experience treating patients with femoroacetabular identify factors affecting its outcomes.
 Methods. Retrospective, uncontrolled, single-center clinical included 128 FAI which had 150 surgeries on 149 joints period from 2013 2021. All underwent physical examination X-ray diagnostics, their type was identified. The alpha angle external part femoral head anterior-posterior position modified Dunn 45 position, as well Tonnis angle, lateral central-marginal Ogata modification height articular gap along (LS) medial edges (MS) sclerosed acetabulum were calculated. i-HOT-33 HOS scales used assess preoperative status postoperative results.
 Results. average follow-up 3.9 years (SD 1.71; min 1.05 max 8.16). 55 (43.0%) women 73 (57.0%) men 64 (42.7%) 86 (57.3%) respectively. common types FAI, according our data, mixed (53% joints) сam (27.5% joints). Insufficient coverage by (borderline dysplasia) combination deformity observed 18.1%. Pincer-type 1.4% joints. We obtained worst results borderline dysplasia comparison cam- mix-type scales. Patients age, deep damage, irreparable labrum damage decrease determined negative effect treatment scales.
 Conclusion. Hip arthroscopy showed good short- midterm outcomes FAI. Pain syndrome often manifested pathology soft tissue structures concomitant insufficient coverage, are important predictors poor results.
