Mini-Subvastus Approach versus Medial Parapatellar Approach in Total Knee Arthroplasty .
The Comparison between Mini-Subvastus Approach and Medial Parapatellar Approach in TKA: A Prospective Double-Blinded Randomized Controlled Trial
Orthop Surg . 2022 Nov;14(11):2878-2887.Fifty-eight patients undergoing bilateral total knee arthroplasty were randomized to receive either the mini-subvastus approach on their left knee or the medial parapatellar approach for their right knee, or vice versa. Outcomes of interest were range of motion, pain at rest and with movement, alignment, time to straight leg raise, hospital for special surgery (HSS), and patient satisfaction. Range of motion on postoperative day (POD) 3, VAS at rest and with movement on POD1 and POD3, recovery time, HSS on POD3, and patient satisfaction were significantly better in the midvastus group. In contrast, the lateral release rate was significantly better in the medial parapatellar group.
