The Oxford Partial Knee has a unique mobile-bearing design which was patented by John Goodfellow and John O’Connor in 1974, and first used in 1976. The Oxford PKR is the only partial knee that’s been clinically proven in survivorship at minimum 10, 15 and 20 years.1-7
Also, the Oxford PKR is a bi-cruciate retaining knee, meaning the healthy ACL and PCL are kept intact. This provides stability and maintains natural kinematics for the patient after surgery. We believe the retention of the ACL is an important contributor to reported higher patient satisfaction following Oxford PKR surgery vs. TKR8.
