NCT03081663

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

EXPERIMENTAL

Participants will have a navigated total knee arthroplasty with a quadriceps-sparing mid-vastus approach and a tourniquet.

Procedure: Quads-Sparing Approach

Medial Para-Patellar with Tourniquet

ACTIVE COMPARATOR

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.

Procedure: Medial Para-Patellar Approach

Quads-Sparing Approach w/o Tourniquet

ACTIVE COMPARATOR

Participants will have a navigated total knee arthroplasty with a quadriceps-sparing mid-vastus approach and no tourniquet.

Model Details: Participants will be randomized to undergo their surgery through either the quadriceps-sparing mid-vastus approach or the medial para-patellar approach and with or without a tourniquet. We will stratify based on which type of analgesia will be used post-surgery, either an adductor canal block or local infiltration.
