title: Cementless total hip arthroplasty in patients 50 years or younger.
abstract: This report examines the mean 9-year results of 100 second-generation cementless total hip arthroplasty in 91 patients 50 years or younger. The mean age at arthroplasty was 39 years (range, 14-50 years), and follow up averaged 9 years (range, 5-13 years). There were 13 revisions (7 related to polyethylene wear and/or osteolysis, 5 for instability, and 1 for infection). No femoral components were revised for loosening and none were radiographically loose. Two acetabular shells were revised for loosening secondary to extensive osteolysis. Ten-year survivorship using revision for any reason as the end point was 87.5%, using femoral component aseptic loosening as the end point was 100%, and using acetabular component aseptic loosening as the end point was 97.1%.
