Functional outcome of posterior cruciate ligament substituted total knee arthroplasty

Abstract

Background and Aim: Total Knee Arthroplasty (TKA) is now most reliable treatment for severe arthritis. However, there is a need of a study to accurately assess and analyze the approach of a surgeon towards PCL and measure its outcome. We aimed to study clinical and functional outcome following posterior cruciate ligament substituted total knee arthroplasty.Material and Methods: Present research was carried out at Department of Orthopedics, Tertiary Care Institute of India where 50 patients were operated, 78 Total knee replacements done on 50 patients for the duration of two years. All patients were assessed clinically and functionally using the Oxford knee score. The preoperative medical evaluations of all patients were done to evaluate any potential complications that can be life-threatening or limb-threatening.Results: Most of the patients in study have excellent outcome 72% followed by good results of 14% after treatment. Out of 50 patients and 6 patient had post op suprapatellar fullness, which was relieved with medications for 3 weeks and 3 patients without no signs of immediate post-operative period, developed infection after 6 months followed which underwent staged revision total knee replacement.Conclusion: Post operatively, patients had pain free joint movements with correction of deformity. In patients with advanced osteoarthritis, gross varus deformity, fixed flexion deformity posterior cruciate ligament sacrificing total knee replacement will give greater mobility and function.
