Partial Knee Replacement
In patients with only
limited knee arthritis, surgeons may elect to perform
partial knee replacement. Unlike total knee replacement
involving removal of all the knee joint surfaces, a
partial knee replacement replaces only one side of the
knee joint. Knee osteoarthritis usually occurs first in
the medial (inside) compartment as this side of the knee
bears most of the weight. In knees that are otherwise
healthy, a partial approach allows the outer compartment
and all ligaments to remain intact. By retaining all of
the undamaged parts, the joint may bend better and
function more naturally.
Leading surgeons in
Oxford, England along with engineers at Biomet,
developed the Oxford® Partial Knee System. It's the only
FDA-approved, free-floating meniscal partial knee system
available in the United States and has been utilized
throughout Europe for more than two decades.
 In a healthy knee,
the meniscus serves as a shock absorber between the ends
of the bones. The Oxford is the first partial implant
with an artificial meniscal bearing designed to glide
freely throughout the knee's range of motion, more
closely replicating normal movement. The free-floating
nature of the device also improves durability of the
implant.
Published long-term clinical results on the Oxford® Knee
demonstrated a 98% success rate at 10 years, equaling
the results of the most successful total knee
replacements.1
Studies also show most patients experience a rapid
recovery and more natural joint function.
