About this product

Division: Knee Reconstruction
Category: Primary Knees

Whilst maintaining all of the LCS design features in the walking phase of gait the LCS-RPS utilises a spine and cam mechanism in flexion. This reduces the potential for A-P translation by keeping the femoral component centralised as the knee goes into flexion. This centralisation reduces the risk of posterior impingement and therefore allows the knee the freedom to achieve deeper flexion angles.

The LCS is well known as a low wear solution due to its design which allows total freedom of rotation resulting in unidirectional motion patterns. To minimise any potential for 3rd body wear the cam and spine in the LCS-RPS have been carefully designed to evenly distribute stresses and to permit the freedom of movement required to allow normal rotation and lift off. Married with the decoupling forces provided by the clinically proven1 Mobile Bearing Tibial tray, the LCS-RPS remains a low wear choice.
