Abstract

Although femoroacetabular impingement (FAI) syndrome is included in the etiology of lesions involving the acetabular labrum and acetabular cartilage, it is one of many possible reasons behind osteochondral lesions in the femoral head. Herein, we present clinical findings and outcomes of two cases with osteochondral defects and cam type impingement of femoral head. Both cases underwent autologous osteochondral mosaicplasty along with femoral osteochondroplasty following controlled hip dislocation. Harris hip scores improved significantly postoperatively and magnetic resonance imaging showed an adequate graft union and formation of a healthy chondral surface at the final assessment. Autologous osteochondral mosaicplasty of parafoveal region defects and femoral neck osteochondroplasty combination may be an effective treatment method for young patients with FAI syndrome. In addition, we believe that cam type impingement may also have a role in the etiology of parafoveal osteochondral lesions.
