Summary

This randomized controlled trial will compare a minimal-incision and soft-tissue-preserving (MISI) technique with the standard surgical technique in patients undergoing robotic-assisted total knee arthroplasty for knee osteoarthritis. A total of 100 participants will be randomly assigned in a 1:1 ratio to undergo either the MISI technique, which uses a reduced skin incision, limited soft-tissue dissection, and modified tracking pin placement, or the standard technique. The primary outcome is postoperative scar assessment at 3 months. Secondary outcomes include incision length, wound oozing, thigh pain and tenderness, recovery of straight-leg raising, tracking pin-related complications, patellar height, patient-reported scar assessments, and functional outcomes during follow-up.

Conditions

  • Osteo Arthritis of the Knee

Interventions

PROCEDURE

MISI Robot-Assisted Total Knee Arthroplasty

Robot-assisted total knee arthroplasty performed using an approximately 10-cm main incision, limited soft-tissue dissection, two femoral tracking pins inserted through the main incision, and one tibial tracking pin inserted through an additional approximately 5-mm incision.

PROCEDURE

Standard Robotic-Assisted Total Knee Arthroplasty

Robot-assisted total knee arthroplasty performed using the standard incision and soft-tissue exposure, with conventional placement of four tracking pins in the femoral and tibial regions and an additional femoral incision.
