Patellofemoral Knee Joint 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 may relieve pain and last for a number of years.
