Functional Outcome of Rotating Platform Versus Fixed Platform of Total Knee Arthroplasty- A Comparative Study
Keywords:Total knee arthroplasty, KSS score, rotating platform, fixed platform
Background: Total knee arthroplasty (TKA) has shown to be a successful and reliable procedure for older, debilitated
patients with knee osteoarthritis. TKA’s indications were widened to include younger and more active patients after its
Objectives: To compare the functional outcome of rotating vs fixed platform of total knee arthroplasty
Methods: All patients who are fit to undergo total knee arthroplasty like advanced stages of osteoarthritis and rheumatoid
arthritis in age group of 50-70 years . We compared the functional outcome between rotating platform versus fixed
platform of Total Knee Arthroplasty. Clinical and radiological follow-up was performed at 1, 3, 6 months and 1year after
the operation. Pre-operative and follow-up ratings according to Knee Society Scoring system were obtained for all the
patients. In addition, a visual analogue scale was used to specially assess the severity of the pain
Results: In group A and group B there were 6 males (30%) and 14 females (70 %). In both the groups the mean post
operative range of movements were significantly improved for the follow-up at every 3months with the mean ROM of
120° achieved at 1year follow-up. The ROM has significantly improved from 90° at 3rd month follow- up to 120° at 1year
follow-up. The mean KSS knee and functional score were gradually improved in post operatively in 3rd, 6th and 1year
follow-up compared to the pre operative KSS score.
Conclusion: The post-operative range of motion and the Knee Society functional score were similar in both groups. There
was no significant statistical difference between the two groups of Total Knee Arthroplasty in terms of post-operative
range of motion and functional outcomes.
