Duracon total knee replacement in Kuwait: A clinical and radiographic analysis of 52 knees followed for 2-5 years

Abstract

Objective: In this prospective clinical and radiological study results of 52 consecutive Duracon bicompartmental total knee arthroplasties in 37 patients with femorotibial arthrosis and rheumatoid arthritis with the average observation time of 3 (2-5) years were analyzed. Methods: The study includes 32 women (44 knees) and 5 men (8 knees) with a mean age of 60 years. Details of implant design and surgical technique were given. Two surgeons performed all the operations. The patients were evaluated by an unbiased observer. The Hospital for Special Surgery (HSS) score for both pre- and postoperative assessment was used. Results: The average initial HSS score of 44 (20-65) improved to 85 (60-99) after operation. By subjective assessment, 41 knees were excellent, 10 good and 1 knee had a fair result. There were no revisions. The mean postoperative flexion was 101°(80-120). The mean anteroposterior angle of the tibial component was 4°of the varus and the mean lateral angle was 3°of the posterior slope. The mean postoperative hip-knee-ankle deviation was 4°of the varus. Conclusion: In Kuwait, the cemented Duracon total knee arthroplasty without patellar resurfacing gave satisfactory clinical results after an intermediate follow-up period of 3 years.
