Purpose: To evaluate the mid-term (over 5 years) clinical and radiologic results of Maxim(R) (Biomet, Warsaw, USA) Cruciate Retaining total knee replacement arthroplasty (TKRA). Materials and Methods: Between Feb. 1997 and Nov. 2000, 103 knees in 65 patients who had been followed up for 5 years after TKRA with Maxim(R) Cruciate Retaining were evaluated retrospectively for clinical and radiologic results. Results: The average range of motion increased from 114˚ (80~130˚) preoperatively to 128˚ (105~130˚) at the last follow-up. The average range of flexion contracture decreased from 6.5˚ preoperatively to 0.8˚ (0~15˚) at the last follow-up. In patients with osteoarthritis, the mean preoperative knee score (59.2) and functional score (40.7) improved to 88.6 and 90.1, respectively. In rheumatoid arthritis patients, the mean knee score and functional score also improved from 47.4 and 39.2 to 80.6 and 88.3. Roentgenographic evaluation revealed a radiolucency rate of 19.5%. Complications were deep infection in 2 cases and periprosthetic fractures in 3 cases. The former had received reimplantations. Conclusion: The mid-term results of Maxim(R) Cruciate Retaining total knee replacement arthroplasty were reliable and satisfactory in terms of improvements of range of motion, restoration of function, and rare complications. However, long-term follow-up evaluation is necessary.
