Clinical and Functional Outcomes Following Modified Intervastus Approach

Background: The modified intervastus (MIV) approach is a new muscle and tendon sparing approach to the knee that is easy to perform and compatible with more extensile approaches such as a quadriceps snip. The study reports the clinical and functional outcomes of patients undergoing total knee arthroplasty (TKA) using the MIV approach. These results will be compared with published results of TKA done utilizing the subvastus approach. Methods: A total of 84 patients underwent TKA using the MIV approach from 2017 to 2019. Clinical and functional outcomes were assessed by recording the knee injury and osteoarthritis outcomes score, visual analog scale for pain, and knee range of motion (ROM). Outcome data was collected preoperatively, on the day of surgery, and postoperatively at 2, 6 weeks, 3, 6 months, 1, and 2 years. Paired sample t tests were conducted to assess the statistical significance observed in the outcomes between different time intervals. Results: All patients were able to walk on the day of surgery. The knee ROM increased significantly by 2 weeks after surgery (9.36%) and a net improvement for knee ROM of 37.89% was observed by the end of 2 years (P
