Evaluation of results of cemented total knee replacement in 30 arthritic knee joints: Short term results (mean 26 months)

Abstract

Background: Total Knee replacement sugery, also called Knee arthroplasty, is a surgical procedure to resurface a knee damaged by arthritis. This study investigates the short-term outcomes of total knee replacement surgeries employing the PFC Sigma Rotating-Platform, posterior-stabilized knee prosthesis. The aim is to assess the clinical and radiological effectiveness of this surgical approach in patients with arthritic knees.Aim: The primary objective of this study is to evaluate the short-term clinical and radiological outcomes of total knee replacement surgeries performed using the PFC Sigma Rotating-Platform, posterior-stabilized knee implant.Methods: A total of 30 knee replacements were conducted in 24 patients, including bilateral total knee arthroplasties, by a single surgical team at Indira Gandhi ESI Hospital, Delhi. Pre- and post-operative Knee Society scores, range of motion, walking ability, and radiological results were assessed at intervals up to 2 years post-surgery. Complications were monitored, and patient subgroups of Osteoarthritis (OA) and Rheumatoid Arthritis (RA) were analyzed separately.Results: Pre-operatively, the mean knee score was 31 points, and the mean functional score was 34 points. Post-surgery, significant improvements were observed, with a mean knee score of 85.68 points and a mean functional score of 71.94 points at final clinical assessment. Clinical outcomes demonstrated 53.33% excellent, 33.33% good, 10% fair, and 3.33% poor results. Analysis of OA and RA subgroups revealed distinct responses to the surgical intervention.Conclusion: The utilization of the PFC Sigma Rotating-Platform, posterior-stabilized knee implant yielded positive short-term outcomes in patients with arthritic knees. Marked enhancements in pain relief, range of motion, walking ability, and overall quality of life were evident. These findings underscore the efficacy of the surgical approach in alleviating symptoms and improving functional capacity in arthritic knee patients.
