Survival analysis of T-28 hip arthroplasty with clinical implications.

Seventeen years after its introduction, the T-28 and its successor (the TR-28) have proved to be a successful arthroplasty system, with very low long-term socket and femoral loosening rates, especially in older patients. The 10-year revision rate for aseptic loosening of the socket is only 2 per cent. This form of conventional cemented total hip replacement has provided pain relief and improved function in many individuals who have exhausted nonoperative treatment alternatives. Although there are still unsolved long-term problems for the young active patients, cemented hip arthroplasty continues to play an important role in joint replacement, and remains the treatment of choice in older and relatively inactive patients.
