Brief Summary
This study is a randomized clinical trial comparing standard medial para-patellar total knee arthroplasty with a quadriceps sparing mid-vastus approach. Patients who are medically well and have a good support structure at home will be randomized to a standard or quadriceps sparing surgical approach stratified by type of analgesia (adductor canal block or local infiltration). We will compare patient satisfaction and costs from the perspective of the Ministry of Health, the institution, society and the patient.

Study Arms (4)
Quads-Sparing Approach with Tourniquet
EXPERIMENTALParticipants will have a navigated total knee arthroplasty with a quadriceps-sparing mid-vastus approach and a tourniquet.
Medial Para-Patellar with Tourniquet
ACTIVE COMPARATORParticipants 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.
Quads-Sparing Approach w/o Tourniquet
ACTIVE COMPARATORParticipants will have a navigated total knee arthroplasty with a quadriceps-sparing mid-vastus approach and no tourniquet.
Medial Para-Patellar w/o Tourniquet
ACTIVE COMPARATORParticipants will undergo total knee arthroplasty with a medial para-patellar approach and no tourniquet. An intramedullary femoral guide and extramedullary tibial guide will be used during the surgery.
