title: Clinical and radiographic results of cementless AML total hip arthroplasty in young patients.
abstract: A retrospective study was undertaken of the radiographic and clinical results and complications of 52 cementless (AML) total hip arthroplasties in 52 patients with a mean age of 48.3 years. The follow-up ranged from 9 to 12 years with a mean of 10.5 years. Of the patients, 88% had good or excellent results. Forty-two patients (81%) complained of anterior thigh pain at 3 months after surgery when weight bearing was allowed. The pain continued for a mean period of 4.3 months. In 4 patients (8%), this pain persisted after the first postoperative year. Calcar resorption was seen in 21 patients (40%), and 16 patients (31%) showed clinically insignificant heterotopic ossification. Four patients required revisions: 1 for acetabular loosening, 1 for persistent thigh pain, and 2 for massive osteolysis of the proximal femur. There were no dislocations, infections, thromboembolic events, or neurologic injuries.
