Patellofemoral Joint Resurfacing

The knee has three compartments, the medial (inside), the lateral (outside) and the patellofemoral (kneecap) compartment. Partial knee resurfacing may be an option depending on the affected surface. During the procedure we remove only the damaged area of the bone in the affected knee and fits the implant to that bone.

For PFR, the implant we use is the Nexgen gender solutions PFJ (Zimmer/Biomet).

Patellofemoral knee resurfacing is a procedure that resurfaces only the worn out kneecap or patella and the groove in the thighbone (trochlea). The procedure is performed using an arthroscope, a small fibre-optic instrument with a tiny lens and a video camera. Through the tiny incisions the damaged part of the patella and trochlea will be removed to create room for the artificial component. The new component is fixed in place with the use of bone cement and the knee is taken through a range of movements.

Advantages of patellofemoral knee resurfacing include:

  • Minimal incisions
  • Minimal hospitalization
  • Reduced blood loss
  • Less scarring
  • Quick recovery
  • Less post-operative pain

Although patellofemoral knee resurfacing is an effective method in repairing the damaged part of the knee, it is associated with certain complications such as infection, blood clot formation, damage to nerves and blood vessels, wear, dislocation, and ligament injuries.
