Two hundred and ninety-nine consecutive patients (323 knees) were implanted with the hydroxyapatite-coated Goeland (Landos, Landanger) total knee arthroplasty. The mean age at the time of surgery was 67 years (range, 46-82 years), and male/female ratio was 1/5.8. The mean follow-up was 15.6 years (range, 12-19 years). Survival analysis showed a cumulative success rate of 99.2% at five years, 96.2% at ten years and 90.4% at 15 years. Three knees were revised due to aseptic loosening, two for knee instability, four for polyethylene damage, two for fatigue fracture of the tibial component and two for non-specific knee pain. Analysis of six retrieved and one unused set of knee arthroplasties showed local inconsistencies of the hydroxyapatite characteristics, with respect to coating thickness, adherence to metal and effective osseointegration potential. Despite manufacturing problems this hydroxyapatite coated knee arthroplasty showed satisfactory long term results.
