Total Knee Arthroplasty In Advanced Osteoarthritis Of Knee

Background:Total knee arthroplasty is being performed for an increasing number of patients with osteoarthritis.Several studies have demonstrated a high prevalence of residual symptoms among total knee arthroplasty patients and functional activity lower than expectations based on age and preoperative diagnosis.Limited studies have specifically focused on specific techniques or implant designs on the patients,but have not identified optimal approaches.Limiting the most common complications that lead to early surgical revision,infection and instability,is important to ensure both short-term symptom resolution and long-term implant survivorship.Objectives:This study aims to evaluate the results of primary total knee arthroplasty in advanced osteoarthritis of the knee joint.Settings:Retrospective studyMethods:This study was done among 40 patients who were diagnosed with advanced knee osteoarthritis in the 1st affiliated hospital of Kunming medical university.Patients with radiological evidence of end stage of knee osteoarthritis were included in this study.These patients were managed with total knee arthroplasty,held during the period of lstjan 2015-1st Jan 2017.The indication of the surgery was severe pain in the knee joint.Result:Participants with age(Mean±SD):66.35±8.29,70%were female,30%were male.52.5%had TKA in left and 47.5%had TKA in the right knee 85%grade 4 and 15%had grade 3 osteoarthritisPreoperative and postoperative pain score was statistically analysed using the fore mentioned method and P-value was found to be<0.001(which is<0.05)(table5 and fig 4);AP stability:P-value<0.001(which is<0.05);Range of motion:P-value was found to be<0.001(which is<0.05).Extension lag:P-value<0.001(which is<0.05).Postoperative follows up in twelve months Mean±SD:6.6842±4.42283.Postoperativecomplications:17.5%had DVT,10%had pneumonia,5%had both pneumonia and DVT and rest of 67.5%of cases had no complication.Conclusion:From this experiment we found out that in patient suffering from grade 3 and 4 of osteoarthritis,total knee replacement seems to improve on the pain severity(measured by using pain scale),show improvement in range of motion,AP stability and extension lag,which are proved by the result section to be statistically significant.
