Background: To evaluate the influence of posterior tibial slope on range of movements following a total knee Arthroplasty. To assess the functional outcome following a total knee Arthroplasty according to Knee Society Score.
Methods: In this study 30 patients with OA knee were studied. All the cases were treated at department of orthopaedics at NMCH, Patna Study duration of Two years. The duration of follow up ranged from 3 weeks to 6 months. All the cases in this study were Primary OA knee. No post traumatic or pathological knees were taken into the study. Post operatively all patients will be subjected to x-ray imaging and evaluated clinically at 3 weeks, 3 months and 6 months for the range of movements and Knee Society Score.
Results: Average flexion in this study at the end of 6 months was about 1150 with an average KSS of 77. Good results were seen in about 80% patients according to the functional outcome- KSS. 2 patients had late onset post-operative infection.
Conclusion: Achieving optimal PTS in CR-TKA is an important variable in obtaining maximal flexion range of motion. The findings in this study suggest that PTS provides for improved flexion range of motion by limiting posterior tibiofemoral impingement via increased rollback. Although flexion and rollback may be improved with initial increases of PTS up to 5°, our data suggest that further increases in PTS above 50 may fail to improve flexion and rollback.
