Midterm results of total knee prosthesis
Özet
Total knee arthroplasty in primary and secondary gonarthrosis is a good treatment method when other treatment modalities fails. The aim of this study is to evaluate midterm results of AGC total knee prothesis in our clinic. AGC total knee prosthesis has been applied to 64 knees of 50 patients in Orthopaedics and Traumatology Clinic of Ondokuzmayis University Medical Faculty between January 1992-January 1998. We evaluated 52 knees of 40 patients who we were able to make follow up controls in regular intervals. thirtytwo of these patients had undergone operation due to osteoarthritis and the other 8 patients due to Rheumatoid Arthritis. We applied bilateral total knee prosthesis in 12 patients. At the time of operation the mean age of the patients was 64.4 (53-76) the mean follow up time was 33.7 (6.67). The patients were evaluated by using Knee Society Score System. We found out that the mean preoperative and postoperative knee scores were 27.8 and 86.7, the mean preoperative and postoperative functional scores were 40.7 and 77.8 respectively. The mean alignment was 3.90 varus before the operation we have been able to change mean alignment to 6.30 valgus after the operation. The mean total range of motion was 84.30 and it is extented 96.20 postoperatively. As a result when indicated and carried out by careful technique we thought that total knee prosthesis procedure will be succesfull.
