Abstract
Between 1976 and 1979, 220 total knee replacements were done on 164 patients using the Total Condylar Knee replacement. The diagnosis was rheumatoid arthritis in 111 knees and osteoarthritis in 109 knees. Patients with 157 knees are known to have died as of December 1998, leaving 63 knees in patients who are still alive. Twelve patients with 18 knees were lost to followup. The average 20-year followup data (range, 18–22 years) are presented for 45 knees in 30 patients using Knee Society evaluations. The average Knee Society clinical score for the surviving patients was 88 points, and the average functional score was 58 points. The radiographic followup averaged 19 years. The average overall alignment was 3° valgus. Femoral lucencies were present in 17 of 40 adequate lateral views, most commonly about the anterior and posterior surfaces. Two femoral components were loose. Twenty-two tibial components had radiolucencies; four radiolucencies were circumferential. The remaining 41 knees retained a well-fixed cemented central peg despite proximal interface lucencies. From the group of 220 knees, 14 revisions have been done at an average of 11.4 years postoperative. Two knee replacements were revised for isolated tibial loosening, whereas one knee replacement had isolated femoral loosening. Three knee replacements were revised for loosening of both components, and one was revised for isolated patellar loosening. Four patients had sepsis develop; three of these four patients were treated with two-stage revision, and one underwent fusion. Three patients were treated for supracondylar fractures. The Total Condylar Knee replacement maintains excellent durability at 20-years followup.
