Use of cementless, tapered femoral stems in patients who have a mean age of 20 years.

Young patients who undergo total hip arthroplasty are a unique group who has been challenging to successfully treat; however, newer prosthetic materials and designs have the potential to increase implant longevity. Fifty-three hips (40 patients who had a mean age of 20 years) underwent a total hip arthroplasty using a cementless, proximally hydroxyapatite-coated, tapered, femoral stem and a cementless acetabular cup. There was a 96% overall survivorship at approximately 5 years of mean follow-up (range, 2-7 years) with no femoral side failures. Younger patients undergoing total hip arthroplasty with newer component designs and materials may have similar excellent outcomes to older patients.
