The primary aim of a knee replacement is to alleviate pain from a joint which is most commonly due to destruction of the joint surface cartilage (osteoarthritis).
We usually try non-operative treatments first, usually in the form of physiotherapy and anti-inflammatory medication. However, once the joint surface cartilage has completely worn out, the only way to remove the pain and improve the function of the knee is to replace the joint using a knee replacement.
Over the last few years there has been a tremendous improvement in our understanding of normal knee movement (kinematics). Traditional knee replacements have not attempted to replicate normal knee movement resulting in a reduced range of motion compared to a normal knee.
Mr. Logan uses the Evolution Medial Pivot Knee system by Microport. The medial pivot system allows the knee to move more like a normal knee with asymmetric motion allowing rotation as well as flexion similar to the natural knee. This design allows great stability and freedom of motion more so than the traditional symmetric knee systems. The functional outcomes and excellent survivorship of the eMP knee makes it one of the best available on the market.
