SAIPH with dome patella
- MatOrtho Limited

The SAIPH®; Knee System is the 2nd generation medial ball and socket knee from the originators of the concept and has been in use since 2009. It follows on from 20 years of clinical success with the Medial Rotation Knee™ (MRK™) and retains all key design features fundamental to the clinical success of the principle. The design is 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 total knee replacement designs. 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.
