"The Oxford® Partial Knee replacement, now in its 35th year, has had a phenomenal clinical track record," said Keith Berend, MD, Joint Implant Surgeons, Inc. in New Albany, Ohio. "Independent studies have shown more than 91%(1) of implants still functioning well 20 years after implantation."
Developed by John Goodfellow, FRCS, and John O'Connor, PhD, at the University of Oxford in the United Kingdom, the Oxford® Partial Knee System was first implanted by Mr. Goodfellow in 1976. Over its 35 years of clinical use, the Oxford® Partial Knee System has demonstrated exceptional reliability with published success rates of 94% at 10 years(1) and 91% at 20 years.(1) It remains the only fully mobile-bearing partial knee system approved by the United States Food and Drug Administration.
The Oxford® Partial Knee uses a minimally invasive surgical technique that may potentially reduce blood loss and has been shown to allow patients a faster recovery. (2,3,4) Surgeons are able to preserve and restore normal knee function and movement by replacing only the diseased compartment of the knee. The procedure removes approximately 75% less bone and cartilage when compared to a total knee replacement.
"Biomet is proud to celebrate the 35th anniversary of the Oxford® Partial Knee System," said Jon Serbousek, Group President of Biomet Orthopedics. "As World Arthritis Day draws our attention to the growing impact of arthritis, it is gratifying to know that we offer a proven and widely used partial knee option for patients with medial knee arthritis."
