Zimmer Biomet Oxford Partial Knee Replacement System
The Zimmer-Biomet Oxford TM Partial Knee Replacement System is the most widely used partial knee replacement system in the world. It is designed to replace either the medial (inside) or lateral (outside) compartments of the knee and has a proven track record of success. The components are designed to anatomically replicate the region of the knee that is being replaced. This allows for more anatomic knee motion following replacement.
Additionally, the component is designed to retain the native cruciate ligaments (ACL and PCL) of the knee which again allows for more normal knee motion following surgery. Some studies have shown that this leads to faster recovery and improved patient satisfaction. The components are introduced through standard anterior incisions overlying the compartment being replaced. The tibial component is designed to replace the portion of the joint at the top of the tibia and the femoral component is designed to replace the bone and cartilage removed from the end of the femur.
These components in this system are manufactured from a Cobalt-Chromium alloy. The polymer plastic surface that is placed between these components is made of a highly crossed linked high-molecular weight polyethylene and demonstrates excellent wear characteristic. As with any surgery, the choice of implants used should be at the discretion of the surgeon and his comfort level with various systems. With this said, the Oxford partial knee replacement system is a great option.
