Abstract

Aim: We purposed to describe the surgical technique and preliminary outcomes of combined arthroscopic and periacetabular osteotomy (PAO) for the treatment of non-arthritic hip dysplasia. Methods: Between May and August 2015, 4 patients (3 female, 1 male) with an average age of 29 years old (range; 22-33) had undergone one-stage hip arthroscopy and periacetabular osteotomy. Primary symptom was pain associated with instability. Upon radiographic examination, mean lateral center-edge angle of Wiberg was 12° (range; 7°-18°). Intra-articular findings were computed and primary outomes were as follows: radiographic angular correction; time to healing after pelvis osteotomy and functional results according to Merle D'Aubigné Score. Results: Minimum follow-up was 6 months whereas maximum was 9 months. Mean surgical time was 98 minutes for hip arthroscopy and 132 minutes for the osteotomy. In all cases, a lesion of the antero-superior labrum and the chondro-labral junction was found and repaired. After correction, overall postoperative center-edge angle was 29° (range; 25°-35°). Bone healing was certified in all cases at 6 months postoperatively. Overall Merle D'Aubigné Score was 17/18 points. Conclusion: Combined treatment of non-arthritic hip dysplasia with hip arthroscopy and PAO obtained good clinical and radiological outcomes. Former arthroscopy enables the diagnosis of cartilage lesions and intra-articular pathology as well as it aids in proceeding or not to an open correction.
