Acetabular labral reconstruction with medial meniscal allograft: preliminary results of a new surgical technique. European journal of orthopaedic surgery & traumatology : orthopedie traumatologie Chen, M. J., Hollyer, I., Pun, S. Y., Bellino, M. J. 2021

Abstract

PURPOSE: 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.METHODS: The results from seven hips (six patients) that underwent this procedure with 1 year minimum follow-up, and radiographs are presented.RESULTS: Six of the seven hips had improvements in pain, hip flexion, hip abduction, and Merle d'Aubigne-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 Tonnis grades.CONCLUSIONS: The medial meniscus is a morphologically and clinically suitable option for labral reconstruction and effectively restores the hip fluid seal.
