Introduction: For late stages of arthritis of knee, total knee arthroplasty (TKA) is the most successful joint replacement surgery for the patients to achieve good function. The medial parapatellar (MPP) approach is most often used, whereas the subvastus approach (SV) is a suitable alternative. Patients and Methods: This is a prospective, observational, comparative study. Results: It has been demonstrated that the approach (SV) is advantageous in the early postoperative period compared to the MPP surgical approach (MPP). The SV group was able to perform straight leg raising earlier, had good pain scores, and experienced better range of motion when compared to the MPP group. The Knee Society Knee Score for pain was also better in the SV group in the immediate postoperative period. Conclusion: The SV approach, which is based on avoidance damage to extensor mechanism and peripatellar plexus of vessels, helps in early rehabilitation after TKA.
