Revision of failed hip surface replacement arthroplasties with a bipolar prosthesis. Three case reports with two- to three-year follow-up observations.

abstract：:Twenty patients underwent operative arthroscopic procedures of the hip joint. All procedures were performed with the patient in the supine position on a standard fracture table using fluoroscopy through three arthroscopic portals (anterolateral, anterior paratrochanteric, and posterior paratrochanteric). The initial i...
