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.
髁突全膝关节置换术的研究与评价
背景:膝关节慢性致残疾病如骨关节炎、类风湿关节炎、炎症性关节炎、骨坏死的发病率呈上升趋势。所以患者更愿意永久摆脱这些状况这只能通过全膝关节置换术来实现。全膝关节置换术通常是一种有效的手术,并能显著改善患者的功能。目的:1)探讨全髁膝关节置换术在骨性膝关节炎和类风湿关节炎中的作用。2)考虑印度患者的社会经济状况和习惯,研究全膝关节置换术在印度患者中的作用。方法:对2008年7月至2010年6月在普纳Sushrut医疗与研究学会的Hardikar医院采用Nexgen LPS高屈曲固定全髁膝关节系统进行的25例33例全髁膝关节置换术进行评估。结果:术后平均随访1年(6个月~ 2年)。根据膝关节社会评分,70%的人表现优异,24%的人表现良好,6%的人表现一般。结论:骨关节炎患者的各项评分指标均优于类风湿患者。疼痛的缓解是可以预见的,而且往往是完全的。到最后随访的x线造影研究未发现假体部件移位、松动、异位骨形成,尽管随访时间可能太短,无法获得这些证据。
