Study and Evaluation of Cases of Total Condylar Knee Replacement

Abstract

Background: The incidence of chronic disabling conditions of the knee such as osteoarthritis, rheumatoid arthritis, inflammatory arthritis, osteonecrosis are on the rise. So patients prefer to get rid of these conditions permanently and this could be done only by means of Total Knee Replacement. Total knee arthroplasty is a generally effective procedure and is associated with substantial functional improvement. Objectives: 1) To elaborate the role of Total Condylar Knee Replacement in osteoarthritic knees and rheumatoid arthritis. 2) To study the role of Total Knee Replacement in Indian patients keeping in mind their socioeconomic status&habits. Method: In the present study 25 patients with 33 total condylar knee replacements were evaluated in Sushrut Medical care&Research Society's Hardikar Hospital, Pune between July 2008 to June 2010 using Nexgen LPS, high flex, fixed total condylar knee system. Results: The patients were followed up for an average of 1 year (range 6 months to 2 years) after the procedure. According to Knee Society Score, 70% had excellent results, 24% good results and 6% fair results. Conclusion: Osteo arthritic cases showed better results in all parameters of the score as compared to rheumatoid patients. Relief of pain is predictable and often total. Rontgenographic study till last follow up did not show shift of prosthetic components, loosening, ectopic bone formation, though it may be too short a follow up for such evidence.
