Oxford Knee or Half Knee Replacement
Also known as an unicompartmental knee replacement, the oxfod knee is used
where one side of the knee cartilage has worn away. It allows the candidate to use the remaining
part of the cartilage for longer.
Some consider this to be a stopgap measure which may allow the candidate up years of respite,
however the candidate will almost certainly require a full knee replacement sooner or later.
is the Oxford Knee (Half Knee)
The Oxford design allows the femur (thigh bone) to always be in equal contact
with the tibia (shin bone). As the knee flexes, the polyethylene component (plastic spacer)
is allowed to move slightly. This allows more uniform contact between the components. Thereby
lowering contact pressures and wear. A study has shown an average penetration rate of only
0.03mm per year at a mean follow-up rate of 10.9 years.
long does the oxfod knee last?
- Survivorship of 95% or more at 10 years from several centers.
- This rivals the best outcome studies for total knee replacements (Total
Knee Replacements are often considered the "gold standard")
- Even though the lateral (outside) and patellofemoral (kneecap) portions
of the knee are not replaced, this implant appears to impede disease spreading to these
areas of the knee.

The oxfod knee has 3 Components, The Femur, Tibia and Polyethylene (plastic)
is the oxfod knee Implanted?
The partial knee replacement is performed through a minimally invasive incision.
The incision is generally 3 - 4 inches long (middle of the patella to the tibial tubercle).
The arthritic portion of bone is then removed from the tibia (shin bone) with a saw. Next,
the arthritic portion of the femur (thigh bone) is removed with a saw and reamer. Finally,
the appropriate size polyethylene (plastic tray) is chosen and inserted after the components
are cemented in position. X-rays are obtained to evaluate component position.
someone with knee arthritis have an Oxford Knee replacement?
No. This implant is indicated for patients that have primarily anteromedial
knee arthritis. The patient must not have significant lateral knee arthritis. Interestingly,
the amount of patellofemoral (kneecap) arthritis does not seem to matter. Studies from Oxford,
England have found that approximately 30% of their patients that have knee arthritis are
candidates for this procedure.
do I know if I am a Candidate for this Procedure?
If your knee pain is primarily located along the inside portion of your
knee, you may be a candidate. Remember, there are many conservative measures to control
arthritic pain (exercise, weight loss, medication (glucosamine, anti-inflammatories), assistive
devices and injections (steroids). When these measures have failed and you are no longer
willing to allow your knee to curtail your activity, surgical intervention may be appropriate.
