SmartKnee Classic™ Primary Knee Prosthesis

 

SmartKnee Classic

The SmartKnee Classic™ is just one of the extensive range of knee implants offered by Orthopaedic Innovation

 

The Classic™ offers a clinically proven design that has been developed as a result of extensive research to be as anatomically accurate as possible, matching the shape and size of the distal end of the femur, proximal end of the tibia and the patella.

 

Accurately determining the ratio between the inside and outside diameters of the knee, as well as the ratio between the anteroposterior diameter, means that the covered area of the bone is increased and the possibility of uneven distribution of local stress on the cutting surface is avoided. Preventing uneven distribution of local stress also ensures that the prosthesis does not sink.

Key Features

 

Significantly reduced wear

The curve-on-curve design of the tibial-femoral articulating surfaces produces even distribution of stress and reduces the wear of the insert

 

Inlaid design for maximum contact

The patella component is an inlaid design which, when compared with an overlaid design, increases the contacted area between the patella prosthesis and patella, so avoiding any possible loosening of the patella component.

 

• Reduced contact stress

The curvature surface of the PS insert stake is specifically designed so that it decreases the contact stress during the flexion movement of the knee joint, subsequently decreasing the wear of the UHMW-PE of the insert.

 

• Robust locking mechanism

The reliable design of the locking mechanism between the insert and the tibial component prevents the micro motion which can wear the bottom surface of the insert.

 

• Maximum flexibility

The knee offers a maximum flexion of 134.5° which is more than adequate to meet the requirements of the majority of patients in their daily life.
