[Good 10-year results following cemented total knee arthroplasty]

The results of primary total knee arthroplasty in patients with a follow-up of 4-10 years are presented. The study population consisted of osteoarthritis as well as rheumatoid arthritis patients. Both groups were analyzed separately for postoperative pain reduction at rest and during activity, as well as for improvement of some daily activities (walking distance, stair climbing). Pain reduction at rest and during activity was maintained during the follow-up period of 4-10 years. The walking distance and the ability to climb stairs improved during the first few postoperative years, but declined in the later postoperative years. Survival curve analysis of the total knee arthroplasty showed good results for osteoarthritis as well as rheumatoid arthritis (estimated probability of survival of the prosthesis at 10 years' follow-up was 94%).
