SIGMA High Performance Partial Knee System

Indications for Use

The SIGMA® High Performance Partial Kneeis indicated for single or multi-compartmental knee replacement in skeletally mature individuals with osteoarthritis, posttraumatic arthritis of the tibiofemoral and/or patellofemoral articular surfaces or a history of gout or pseudogout. DePuy Synthes Joint Reconstruction’s SIGMA® High Performance Partial KneeSystem is intended to provide increased patient mobility and reduced pain by replacing the damaged knee joint articulation in patients where there is evidence of sufficient sound bone to seat and support the components.

Features & Benefits

Features Benefits
Options The system’s implants are designed to treat degenerative joint disease one compartment at a time: medial uni, lateral uni and patellofemoral. This allows the surgeon to replace only the affected compartment, leaving healthy bone, cartilage and ligaments intact. The modularity of the system addresses one of the main reasons for early intervention revision, disease progression. 


The modularity of the system allows for a variety of component placement scenarios and provides an accurate fit to patient anatomy. The modularity of the system also addresses one of the main reasons for early intervention revision, disease progression. Bi-compartmental replacement is possible as either a simultaneous or staged procedure. 
Normal Kinematics and High Flexion Because of the ability to maintain the ACL with this system, normal kinematics in activities of daily living can be achieved. The uni components are designed for patients who require a higher than normal degree of flexion, providing support up to 155 degrees.
Low Wear The combination of a highly polished cobalt chrome tray with a moderately cross linked polyethylene insert is designed to help reduce backside wear.1
Fully Instrumented Surgical Techniques and Bone Preservation The system is complemented by High Performance instruments offering precision, efficiency and accuracy. The surgical technique using these instruments is robust and reproducible, taking only the amount of bone necessary, preserving bone and soft tissue.
