Objective: To evaluate the early results of patients in a single institution who underwent total knee arthroplasty using an implant system. Methods: We retrospectively reviewed 76 total knee replacements using the Genesis II prosthesis (Smith and Nephew, Memphis) in 60 patients (16 were bilateral cases) performed between February 2005 and February 2008. Patient related outcomes and clinical evaluations were done by an independent observer. Knee function and patient satisfaction were evaluated using the American Knee Society (ASK) score and the Western Ontario and Mac Master University Osteoarthritis Index (WOMAC). Results: The mean age of the patients at the time of operation was 63.5years. The mean follow up period was 1 year 5 months. At the final follow up, the mean Knee Society Knee Score was 87.9 with 77.3% (58 knees) rated excellent, 21.3% (16 knees) rated good and1.3% (1 knee) rated fair; none were rated poor. The mean Function Score was 87.1 with 64% (48 knees) rated excellent, 29.3% (22 knees) rated good, 6.7% (5 knees) rated fair, no knee was rated poor. The mean WOMAC Score was 94.4 (standard deviation 6.59). Conclusion: Most patients treated for knee osteoarthritis with total knee replacement showed high rates of excellence and good early functional outcomes.
