IDENTIFICATION OF PREDISPOSING FACTORS FOR RECOVERY OF RANGE OF MOTION OF KNEE AFTER TOTAL KNEE ARTHROPLASTY

Abstract

BACKGROUND: Knee joint arthroplasty is the standard treatment for severe dysfunction of the knee aiming to make the knee pain free as well as to stabilise it with an appropriate range of motion. \nAims and objectives: To assess whether the postoperative functional recovery of range of motion of total knee arthroplasty depends on objective and subjective parameters. \nMATERIAL AND METHODS: A prospective study comprising of twenty six cases who underwent total knee arthroplasty had been carried out from November 2013 to October 2015, in the in the Orthopaedics Department of IPGMER and SSKM Hospital, Kolkata, West Bengal, India. \nRESULTS: The mean age group in our study is 35.3 years and 69.2% were females. Left side surgeries were more common (57.7%). Mean fixed flexion deformity decreased significantly from 10.8396 to 0.7692 postoperative 1 year. Mean preoperative extension lag was 2.3077 degrees and postoperative extension lag was 4.0385 degrees. \nCONCLUSIONS: Total knee arthroplasty is the standard treatment for severe destructive arthritis of the knee with an aim to provide stable, painless and mobile joint. Based on the findings of this study, preoperative arc of flexion, mediolateral laxity and preoperative tibiofemoral varus/valgus angle have a significant influence on the postoperative flexion, which means they are important factors for predicting the outcome range of motion of the knee after a total knee arthroplasty. \nKeywords: Total Knee Arthroplasty (TKA).
