Abstract

Objective. The aim of the study was to analyze pre- and post-operative results and factors that may have influenced knee function in 1 and 7 years after surgery. Methods. A prospective study of 120 patients, who undergone total knee arthroplasty (TKA) because of osteoarthritis (OA) was conducted. 56 patients remained for 7 year follow up. Various parameters were analyzed: patient factors, mechanical axis, range of motion, Geriatric Depression Scale (GDS), symptomatic spinal disorders and the Knee Society Score (KSS) were evaluated. Results. It was found that after 1 year the knee function improved significantly comparing pre-operative, 1 and 7 years postoperative results, however after 7 years it slightly diminished. The study found that worse GDS and symptomatic spinal disorders significantly influenced worse KSS outcome. Conclusion. The results of this study showed that after 1 year the function of the knee joint significantly improved and remained better after 7 years after TKA as compared to preoperative. It is important to control symptoms of spinal disorders and depression as it affects the postoperative knee function.
