The adhesions form between the joint capsule and the resected area on the femoral neck and may lead to soft tissue impingement. Recently, intraarticular adhesions between the femoral neck and joint capsule have been identified as an additional cause of postoperative groin pain. ![]() Joint degeneration with joint space narrowing and/or osteophyte formation, insufficient correction of the acetabula, and femoral pathology are known factors for unsatisfactory outcome. There are several reasons for persisting groin pain. ![]() Unsatisfactory outcome is mainly related to pain, located either in the area of the greater trochanter or in the groin. Using the Merle d’Aubigné score and qualitative categories, recent studies suggest good to excellent outcomes in 75% to 80% of patients after open surgery with dislocation of the femoral head. Surgery is intended to remove the cause of impingement with hip dislocation and resection of osseous prominences of the acetabular rim and of the femoral head-neck junction. Femoroacetabular impingement (FAI) is an established cause of osteoarthrosis of the hip.
