• AIM
    • The purpose of our study was to evaluate retrospectively the mid-term results of the Miller-Galante II (Zimmer, Warsaw, USA) unicondylar knee arthoplasty (UKA).
  • METHOD
    • The study included 46 patients with medial UKAs. Mean follow-up time was 7.0 years (range 2.7-13.1 years).
  • RESULTS
    • Survival rate of the prosthesis was 86.6% (95% CI 73.7-99.6) at 7 years. The mean clinical and functional Knee Society Scores had increased from 51 and 62 points preoperatively to 76 and 93 points (P < 0.001) postoperatively. Five of the 46 knees were revised because of excessive wear of the polyethylene liner, and three due to progression of the osteoarthritis in the lateral compartment of the knee.
  • CONCLUSION
    • Survival of this fixed-bearing UKA was not as good as previously reported and polyethylene wear seems to be a more common problem than previously assumed.
