Outcome of Total Knee Replacement via Two Approaches in Indian Scenario.

ABSTRACT

This study was designed to assess the early and late clinical and functional outcome based on Knee Society Score in patients undergoing total knee replacement (TKR) by medial parapatellar approach/midvastus approach. A total of 52 patients were included in the study of whom 28 patients were operated by medial parapatellar approach and 24 by midvastus approach. Patients were assessed on the basis of Knee Society Score, along with other parameters such as duration of hospital stay, blood loss during, and after surgery. The patients were followed up at 2 weeks, 6 weeks, 3 months, 6 months, and 1 year. The knee objective score showed significant better scores in midvastus group at 2 weeks, 6 weeks, and 3 months, but the score in both the groups was not significant at 6 months and 1 year. The knee functional score showed significant better score in midvastus group at the end of 2 and 6 weeks. However, score in both the groups was not significant by the end of 3 months, 6 months, and 1 year. Patients' satisfaction and expectation scores were similar in both groups at all time intervals. The functional outcome of TKR surgery by midvastus approach was better in the first 3 months in comparison to medial parapatellar approach.
