Medium-term results of thrust plate prostheses for osteoarthritis of the hip.

We retrospectively evaluated the results of 61 patients (67 hips) who underwent total hip arthroplasty using the thrust plate prosthesis (TPP) for osteoarthritis of the hip joint. All patients were followed-up at least two years (mean: 37.2 months). Mean preoperative Harris hip score improved from 45.8 (SD: 13.5) to 94.9 (SD: 5.4) points postoperatively. Revision was performed in five cases. Medium-term results of TPP are promising.
