Our St Leger range includes fixed and mobile bearings for both cruciate retaining and posterior stabilised configurations.
The Superica medial pivot knee is currently available in a fixed bearing cruciate retaining option. The Medial Pivot knees are gaining popularity due to the excellent clinical results and the significant number of patients who forget they have a knee implant
Knee Systems

St Leger Cruciate Retaining C/R

Some potential advantages of cruciate retaining prosthetic designs include preservation of bone, more normal knee kinematics, increased proprioception, femoral rollback on the tibia during flexion and greater stabilization of the prosthesis.
The PCL also helps to prevent anterior translation of the femur on the tibia.

St Leger Posterior Stabilized P/S

Some potential advantages of posterior stabilised prosthetic designs include a less technically demanding procedure, a more stable component interface with an increased range of motion.

Superica Medial Pivot M/P

The potential advantages of M/P prosthetic designs include anatomic implant design with a ball and socket articulation throughout the range of motion.
These features work together to enhance stability, drive normal knee kinematics and reduce wear.
This option is gaining popularity amongst medical professionals as these M/P implants are receiving relatively high patient satisfaction ratings.

Instrument Sets

Each knee system has a dedicated instrument set that is supplied in a number of metal cases.
These instrument sets and the implants are all produced in our manufacturing facility.
