Participants will have a navigated total knee arthroplasty with a quadriceps-sparing mid-vastus approach and a tourniquet.
Participants will undergo total knee arthroplasty with a medial para-patellar approach and a tourniquet. An intramedullary femoral guide and extramedullary tibial guide will be used during the surgery.
