Medial Rotation Knee (MRK), Cemented, CS, fixed bearing tibial tray, standard poly insert, uncemented saddle patella
The Medial Rotation Knee™ (MRK™) is the original medial ball and socket knee and has been in clinical use for over 20 years. The MRK™ design was based on the principle that by providing natural functional and anatomical asymmetry in all three compartments, better function and increased patient satisfaction can be achieved without the compromises of traditional TKRs. The result is complete inherent stability throughout the range of motion, coupled with allowance for physiological rotation during flexion. The design also features a physiologically asymmetric patellofemoral joint for a more natural feel and ease of flexion. Overall, the MRK™ is associated with high functional scores and high rates of patient satisfaction.
