[Outcomes of cementless total hip replacement in treatment of osteoarthritis].
OBJECTIVE
To evaluate the clinical results of cementless total hip replacement (THR) in treating osteoarthritis and identifying the factors affecting the results.


METHODS
From January 1995 to December 1999, 76 patients(85 hips) with osteoarthritis of hip joint were treated. These patients were assessed according to Harris hip score and X-ray film. The average follow-up time was 49.3 months.


RESULTS
The average Harris score in the patients was 90.9 points. The excellent or good rate was 91.9%(75/85). Pain in the thigh existed in 23 hips(27.5%). The femoral osteolysis occurred in 14 hips(16.5%). The radiographical result demonstrated femoral loosening in 2 hips. Harris score became lower when the femoral component was placed in varus position.


CONCLUSIONS
Cementless THR has been applied successfully to treatment of osteoarthritis of hip joint. Pain in the thigh may be related to the varus placement of femoral component and femoral osteolysis. Femoral osteolysis is one of important factors affecting the long-term outcomes.
