Patellofemoral Arthroplasty

By Amelia Son, PTA

Patellofemoral Arthroplasty is a procedure to replace the surfaces of the kneecap and the femoral groove if they are damaged or have severe arthritis.

What is a Patellofemoral Arthroplasty?

The quick answer is that a patellofemoral arthroplasty is replacing the joint between the knee cap and thigh bone.  That is why patellofemoral arthroplasty is considered a “partial knee replacement.”  While this is an alternative to a total knee replacement, it is specific to the damage and arthritis patients have in their knees and is not for all knee patients with arthritis.

Arthritis, damage resurfaced, and replaced in a patellofemoral arthroplasty are limited to specific areas of the knee, including the kneecap and the femur’s underside, specifically the groove on the femur where the kneecap sits.  This particular procedure is often easier to recover from since it is done through a much smaller incision and soft tissue damage is limited compared to a total knee replacement.  The following list notes the advantages of a partial knee replacement to a total knee replacement;

  • Quicker recovery
  • Smaller surgical incision which in turn decreases surgical trauma
  • Less overall blood loss
  • Decreased complications from surgery and recovery
  • Increased function and activity after full recovery
  • More natural feeling than total knee due to bone, cartilage, and ligaments that remain in the joint

What Is Recovery Like after a Patellofemoral Joint Replacement?

Patellofemoral arthroplasty or joint replacement is helpful for those with severe arthritis between the kneecap and the thigh bone.

While the recovery is easier in a patellofemoral arthroplasty than a total knee replacement, there are still steps to ensure a good recovery and avoid complications.

  1. The first step to a good recovery is pain management.  Like with all surgeries, there will be pain after the procedure.  Your surgeon will more than likely prescribe you pain medication to help combat the pain. Progressing to over the counter NSAIDs after the prescription runs its course.
  2. Weight-bearing is also a vital part of your recovery to ensure healthy healing.  You should put weight on your new joint immediately. Use whatever walking aid makes you feel the most comfortable and stable. Eventually weaning off the aid and walking independently.
  3. Physical therapy is also an important step to recovery after your surgery.  Physical therapists will provide you with specific exercises to strengthen your joint and increase your range of motion to reach a fully functional level.  They will make sure to include a home exercise routine to perform and work with you to schedule in-clinic appointments to return to the full performance of your activities of daily living.
