Abstract Background Hip resurfacing is a conservative type of total hip arthroplasty but its use is controversial, especially in patients with osteonecrosis. The anter-lateral approach is less damaging to femoral head blood supply than the posterior approach during hip resurfacing. All patients were evaluated clinically and radiologically before and 60 months after the operation.

Pain, function, deformity, and range of motion were evaluated with the use of the Harris hip score [ 14 ]. The radiographic analysis showed no component migration or collapse. Related Articles.
