Computer navigation for total knee replcement

August 11th, 2016 (No Comments)

When performing Total Knee Replacement it is important to have the implants well aligned. This enables the weight bearing axis to fall evenly through the implant, and thus ensure its longevity. In much the same way as poor wheel alignment in your car causes uneven tyre wear, if your knee replacement is poorly aligned it […]

Travel after joint replacement

July 28th, 2016 (No Comments)

Generally, it is safe to travel long distances by plane from 6 weeks post joint replacement. This seems to be the higher risk period for complications such as Deep Vein thrombosis (DVT) and Pulmonary Embolus (PE). After 6 weeks, the risk has returned to normal background levels. Of course, all patients present different individual risk […]

Computer navigated total knee arthroplasty is a proven and useful technique to help plan, execute and document knee replacement procedures.

Computer Navigated Knee Surgery gives insights into Knee movement pre and post operatively.

The figure below shows the range of motion and stability parameters of a knee before replacement surgery. It confirms a varus (bowed) knee with poor movement. After surgery, the knee moves better and demonstrates a more normal alignment. Surgeons and patients benefit from the information computer navigation brings to the operating theatre.
