Brief summary

The aim of this project is to identify which of the two most commonly used techniques for ligament balancing results in better functional and radiological outcomes in total knee replacements. The difference between the two techniques is mainly regarding the order things are done. In one technique (balanced resection), the tibial bone cut is made and the joint is opened up using a distracter device and the ligaments balanced before the femoral bone cuts are made. In the other method (measured resection) all the bone cuts are made prior to ligament balancing. Ligament balancing is described simply as a way of obtaining a rectangular and even flexion/extension gap by modifying the ligaments around the knee.

Interventions

Balanced resection: This is a method whereby the surgeon uses a tensor balancer device to distract the joint to be able to produce an equal and rectangular flexion/extension gap through ligament balancing before the femoral cuts are made. The duration is usually no longer than 15 minutes.
