Ligament Balancing in Total Knee Arthroplasty
Sponsor: Oslo University Hospital
Summary
The goal of this interventional pilot study is to evaluate if performing ligament balancing on the medial collateral ligament (MCL) in a more systematical manner with a novel instrument can produce more objective and repeatable ligament lengthening in Total Knee Arthroplasty. The main questions it aim to answer are: 1. Is it feasible to perform systematic ligament balancing on the MCL using a novel instrument? 2. Can a novel instrument for ligament balancing acquire more objective and repeatable results, without risk of injury? Participants must consent prior to the surgery, but inclusion is only done once ligament balancing is indicated during surgery. Patients will be follow-up as standard protocol for Total Knee Arthroplasty patients at the hospital.

Interventions
A novel instrument for ligament balancing in total knee arthroplasty
Patients will be evaluated perioperatively for ligament balance. When indicated, the novel instrument will guide puncturing of the medial collateral ligament in a systematic and step-wise fashion. Achieved ligament balance will be observed and controlled by computer navigation and a ligament tensor. Performed at Bærum Hospital vestre Viken Hospital Trust.
