Hip arthroscopy using the lateral approach

The benefits of hip arthroscopy are apparent. It produces little postoperative morbidity and can be performed on an outpatient basis. The prompt recovery from the operation is also beneficial, particularly for elderly patients. Distraction of the hip by traction on a fracture table is necessary. Suggested indications for this procedure include synovectomy and synovial biopsy; removal of loose bodies; removal of debris after a closed reduction of a fracture-dislocation; evaluation and treatment of osteochondritis dissecans; evaluation for arthroplasty; and unresolved hip pain. Whether the lateral approach is useful in the following situations is yet to be explored: (1) Evaluation of pediatric conditions such as Legg-Perthes disease and congenital dislocated hip; (2) treatment of localized infection; (3) removal of entrapped methylmethacrylate in total hip replacement; and (4) reducing and fixating an acetabular fracture (M. Brennan, oral communication, April 6, 1987). Arthroscopy of the hip joint by the lateral approach is a valuable addition to the evaluation and treatment of hip disorders.
