Acetabular labral reconstruction with medial meniscal allograft: preliminary results of a new surgical technique.

Abstract

Reconstruction of the acetabular labrum during femoroacetabular impingement (FAI) surgery is accepted when the labrum is deficient and irreparable. Here we describe a novel technique using fresh-frozen medial meniscal allograft for labral reconstruction during surgical hip dislocation for correction of pincer FAI due to acetabular overcoverage. The results from seven hips (six patients) that underwent this procedure with 1 year minimum follow-up, and radiographs are presented. Six of the seven hips had improvements in pain, hip flexion, hip abduction, and Merle d'Aubigné-Postel scores. Only one patient with pre-existing osteoarthritis underwent reoperation with conversion to total hip arthroplasty. All digastric trochanteric osteotomies healed, and there were no cases of femoral head osteonecrosis or progression of Tönnis grades. The medial meniscus is a morphologically and clinically suitable option for labral reconstruction and effectively restores the hip fluid seal.
