Unicompartmental arthroplasty using the Marmor modular knee was performed on 30 knees of 28 patients with unicompartment osteoarthritis between 1976 and 1982. Twenty-five of these knees, in 2 men (3 knees) and 21 women (22 knees) whose average age at surgery was 70.0 years, could be followed up for more than a year. The average length of follow up was 6.1 years (range, 1.1-12.7) . Medial replacement was done in 23 knees, and lateral replacement in 2, and 15 knees of 13 patients, 2 men and 11 women, were followed up for an average of 7.9 years (range, 5.3-12.7) . The thickness of the tibial component used in the arthroplasty was 6 mm in 12 knees, 9 mm in 10 and 12 mm in 3. The overall preoperative knee score, as evaluated by the JOA assessment criteria for evaluation of osteoarthritis of the knee, was 50 ± 12 points and the postoperative one was 77 ± 16 points. The mean score of the knees which were followed up for more than 5 years was 51 ± 13 points preoperatively and 75± 19 points at the final examination. The preoperative femoro-tibial angle was 186.7 ± 7.0 degrees and the postoperative 177.7±8.4 degrees in the knees with medial replacements.
