“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.”
