Avon^® Patellofemoral Knee System

Patellofemoral Knee Resurfacing

Patellofemoral pain (anterior knee pain) is pain felt between the patella (kneecap) and the thighbone. Patellofemoral Knee Resurfacing is a procedure that resurfaces the worn patella and the trochlea (the groove at the end of the thighbone) to alleviate this pain.

With the Avon^® Patellofemoral Knee System, joint resurfacing may be an alternative to total knee replacement for patients with patellofemoral arthritis. It is designed to reproduce the natural patellofemoral joint throughout movement and facilitate sliding of the patella along the end of the thighbone. It is also designed to produce a natural-feeling knee with comfortable and reliable function.

The Avon^® Patellofemoral Knee System is the only one with up to 5 years of published clinical results with 90% success in over 100 knees.¹

Following a patellofemoral knee resurfacing, you may be able to get up and walk on the first post-operative day and start an active range of knee movement. Ninety degrees of knee movement may possibly be achieved within 4-6 days; patients can be discharged within this period.

All knee implants (including total knee implants) have a limited life expectancy. Based on your age, weight, and activity level, a PKR implant can relieve pain and last for a number of years.

Potential Benefits of PKR

Because the PKR artificial joints are smaller than total knee implants, the surgical incision may be smaller. A smaller incision may lead to a smaller scar. Other potential benefits to PKR include a quicker operation and a shorter hospital stay compared to a total knee replacement.² Rehabilitation may also be more progressive. Because less bone is removed and there is less trauma to soft tissue during surgery, your knee may feel more natural than a total knee replacement.

Not all patients are candidates for a Partial Knee Resurfacing. Depending on your condition, a total knee replacement may be recommended by your doctor.
