A 22-year-old hockey player with mechanical right hip pain. A Sagittal T2-weighted image of the right hip demonstrates evidence of anterior labral pathology arrow . B Arthroscopic view from the anterolateral portal identifies a radial fibrillated tear of the anterior labrum. The probe has been introduced from the anterior portal. C The damaged tissue is debrided with a full-radius resector. rotation of the hip also helps in delivering the ligament to the shaver brought in anteriorly. The most posterior portion of the fossa and the acetabular attachment of the ligament may be best accessed from the posterolateral portal. Indiscriminate debridement of the ligamentum teres should be avoided because of its potential contribution to the vascularity of the femoral head. Case 4 A 16-year-old female cheerleader was referred with a 2-year history of intermittent pain and catching of her left hip following a twisting injury. Arthroscopy revealed a rupture of the ligamentum teres Figure this was debrided with prompt symptomatic improvement Figure C . Synovial Disease Various types of primary synovial disease have been encountered in the More often secondary sy novial proliferation may occur in response to other intraarticular pathology. A focal pattern of synovitis may occur emanating from the pulvinar within the acetabular fossa and is limited to this area. These lesions may be dense and fibrotic or exhibit proliferative villous characteristics. Presumably because of entrapment within the joint these lesions can be quite painful and respond remarkably well to simple debridement. More diffuse synovial patterns involve the lining of the capsule. A complete synovectomy cannot be performed but a generous partial synovectomy can be carried out. This procedure necessitates access to the peripheral compartment after the traction has been released. Case 5 A 22-year-old woman was referred with a 3-year history of poorly defined
