Is hip arthroscopy useful for the treatment of borderline dysplasia? A case-controlled study:

Introduction:The idyllic treatment of hip dysplasia is periacetabular osteotomy (PAO). Since the indication of arthroscopy as a unique action is controversial in the treatment of dysplasia, our objective was to analyze its clinical and radiological results in a cohort of patients with borderline dysplasia and compare them with controls with femoroacetabular impingement (FAI).Material and methods:We retrospectively analyzed a group of 29 patients with a labral lesion secondary to borderline hip dysplasia (group 1) and another group of 197 patients with FAI (group 2) treated with hip arthroscopy, evaluating reoperations and joint survival as the main outcomes. Only patients with both diagnoses treated with hip arthroscopy and with a minimum follow-up of 2 years were included. We excluded patients with coxa profunda, patients who only underwent labral debridement, revisions, cases with dysplasia initially treated with PAO and those with previous ipsilateral hip pathology such as local neoplasia, avascular ne...
