Standard hip arthroscopy emphasizes access to disease within the peripheral compartment. The author describes precise access to the central compartment for removal of space-occupying lesions within the cotyloid fossa. These lesions can compromise the space available for the ligamentum teres and poss

Intra-articular tumors and tumor-like conditions of the hip are rare. When they occur, they can interrupt normal articular congruency, leading to pain and joint dysfunction. If these conditions result in large osteochondral defects, they pose challenging reconstructive problems in young patients. We

Femoral head fractures associated with acetabular fractures are usually treated by an open method. After a closed reduction of a hip dislocation, open reduction and internal fixation of acetabular fractures usually depend on the type of acetabular fracture. Acetabular fractures associated with femor
