Comparison of Minced Cartilage Implantation Versus Microfracture for Acetabular Chondral Lesions Due to FAI (Femoro-acetabular Impingement)

Sponsor: GCS Ramsay Santé pour l'Enseignement et la Recherche

Summary

A femoroacetabular impingement (FAI) is an abnormal contact between pelvis and the neck of femur. It occurs particularly when patient bends his hip and causes damage to the cartilage. In the long term, FAI can lead to the development of osteoarthritis (cartilage destruction) and may require a total hip replacement (THR). Surgery to treat cartilage damage in the hip aims to maintain joint function and delay the onset of osteoarthritis. Microfracture remains the most commonly used treatment for cartilage lesions. It is a surgical technique for repairing articular cartilage that works by creating tiny fractures in the bone, which in turn stimulate the growth of new cartilage. Cartilage autografting is a promising alternative to microfracture, offering good results in the knee joint. Cartilage autografting involves the use of autologous cartilage tissue (taken from patient body), which is harvested, ground up and reimplanted in a single surgical procedure to promote the growth of new cartilage and repair. The published literature lacks large-scale studies comparing autologous cartilage transplantation with traditional joint-preserving surgeries, such as microfracture. This is the reason why this study is set up.
