Total knee replacement surgery is considered as a treatment of choice in patients with advanced arthritis, especially in patients where conservative treatment have been failed. Total knee replacement is considered as second most successful surgery in Orthopaedics, which gives good pain relief, function and disabilities following advanced arthritis.
Materials & methods: 60 primary total knee replacement surgeries in 50 patients done using posterior stabilized (PS) Depuy’s allpoly fixed bearing tibial cemented components, who were operated between March 2015 to August 2015, were prospectively enrolled into our study. This study was conducted at SS Institute of Medical Sciences & Research Centre, Davanagere, Karnataka. They were followed up for a minimum period of 1 year, and evaluated using knee society score. There were 24 right knees, 16 left knees, 10 bilateral knees.
Results: There was a significant improvement in function of the patients and we have achieved excellent results in 42 patients and good results in 8 patients, no patient had a poor result. At one year follow up an average pre-op Knee Clinical Score of 28.28 improved to an average postop Knee Clinical Score of 94.23 and an average pre-op Knee Functional Score of 41.67 improved to an average post-op Knee Functional Score of 87.33.There was no case of infection or radiolucency’s at the end of one year.
Conclusion: Among 50 patients who were diagnosed with primary osteoarthritis of knee, pain and deformity were the main presenting complaint. Inability to flex the affected knee and difficulty in doing activities like squatting and sitting cross legged was seen in most of the patients. In Indian scenario where patient comes late with gross varus deformity and fixed flexion deformity, it is difficult to balance the knee with retention of posterior cruciate ligament, where as Posterior Cruciate ligament Substituting Total Knee Replacement gives reproducible and good results, hence it is the preferred mode of management.
