Functional outcome of patients with osteoarthrosis of knee in south Indian population treated with total knee arthroplasty using all polyethylene tibial component: A prospective analysis

Abstract

Introduction: Osteoarthrosis is the commonest of all joint diseases. Degenerative arthritis of the knee is a common affliction in our Indian population with major functional, medical, psychosocial and financial effects on the affected person, family and society. Knee replacement provides a way to overcome all afflictions of arthritis and is one of the most successful orthopaedic surgeries with immense patient satisfaction. Aim of the study: To analyse the functional outcome of patients with Osteoarthrosis of knee treated with Total Knee Arthroplasty using all – poly Tibial component based on the range of motion, radiological measures and associated complications.Materials and methods: This is a prospective study of Osteoarthrosis of the knee joint and treated with Total knee arthroplasty using all-poly Tibial component during the period from June 2016 to August 2018 at Rajah Muthiah Medical College Hospital. A total of 14 total knee replacements done on 14 patients were included and followed up in the study. The pre-operative status and the post-operative functional outcome and pain relief of our patients were assessed using the Knee society scoring system and Visual analogue scale respectively.Results: 12 patients had excellent results, 2 patients had good results. 12 patients were satisfied following their replacements (80%), 2 patients (20%) were not very satisfied and none of the patients were dissatisfied. The commonest complications we encountered were knee stiffness, persistent knee pain and transient foot drop.Conclusion: The results of total knee arthroplasty using all polyethylene tibial component in our study population, when treated with standard operative techniques, post-operative rehabilitation protocol, proper patient education and lifestyle modification are comparable to that of any other prosthesis used for TKR.
