Patellofemoral Knee Replacement

Patellofemoral Knee Replacement surgery may be recommended by your surgeon if you have osteoarthritis contained to the patellofemoral compartment and you have not obtained adequate relief with conservative treatment options.

Traditionally, a patient with only one compartment of knee arthritis would undergo a Total Knee Replacement surgery. Patellofemoral Knee Replacement is a minimally invasive surgical option that preserves the knee parts not damaged by arthritis as well as the stabilizing anterior and posterior cruciate ligaments, ACL and PCL. This less invasive bone and ligament preserving surgery is especially useful for younger, more active patients as the implant placed more closely mimics actual knee mechanics than does a total knee surgery.

The smaller implants used with a partial knee replacement surgery are customized to the patient’s anatomy based upon CT scans of the patient’s knee. A surgical Robotic Arm assists the surgeon with preoperative planning and intraoperative component placement, positioning, and alignment. Patellofemoral Knee Arthroplasty surgery will not alter the ability of the patient to eventually move to a Total Knee Replacement in the future should that become necessary.

Partial Knee Replacement surgery is performed in an operating room under sterile conditions with the patient under general anesthesia or spinal anesthesia with sedation. It is usually performed on an outpatient basis as day surgery.

  • The surgeon makes a small incision, about 3-4 inches long over the knee.
  • With the assistance of the robotic arm, the patellofemoral compartment is prepared for the artificial components by removing the damaged part of the patella and trochlea, the groove at the end of the femur.
  • The new artificial components are fixed in place with the use of bone cement.
  • The femoral component is made of polished metal and the patellar component looks like a plastic button which will glide smoothly in a groove located on the femoral component.
  • With the new components in place, the knee is taken through a range of movements.
  • Once the surgeon is satisfied with the results, the arthroscope and surgical instruments are removed and the incisions covered with a sterile dressing or biologic glue.

Post-Operative Recovery

Common Post-Operative guidelines include:

  • You will be taken to the recovery room and monitored for any complications.
  • You will be given pain medication to keep you comfortable at home.
  • You will need someone to drive you home due to the drowsy effects of the anesthesia.
  • Swelling is normal after knee surgery. Ice, compression, and elevation of the knee will be used to minimize swelling and pain.
  • You will be given specific instructions regarding activity. Usually there are few activity restrictions.
  • You will be referred to a rehabilitation program for exercise and strengthening.
  • Eating a healthy diet and not smoking will promote healing.

Risks and Complications

Specific Complications related to Patellofemoral Knee Replacement surgery include:

  • Infection: Infection can occur with any operation. In the knee this can be superficial or deep. Infection rates are approximately 1%. If it occurs it can be treated with antibiotics but may require further surgery.
  • Deep Vein Thrombosis: DVT are blood clots that can form in the calf muscles and travel to the lung (Pulmonary embolism). These can occasionally be serious and even life threatening. If you get calf pain or shortness of breath at any stage, you should notify your surgeon.
  • Ligament injuries: There are a number of ligaments surrounding the knee. These ligaments can be torn during surgery or break or stretch out any time afterwards. Surgery may be required to correct this problem.
  • Injury to blood vessels or nerves:Also rare but can lead to weakness and loss of sensation in part of the leg. Damage to blood vessels may require further surgery if bleeding is ongoing.
  • Arthrofibrosis: This is the development of thick, fibrous material around the joint that often occurs after joint injury or surgery and can lead to joint stiffness and decreased movement.
  • Wear: The components eventually wear out over time, usually 10 to 15 years, and may need to be changed.
    • Dislocation: An extremely rare condition where the ends of the knee joint lose contact with each other.
    • Fractures or breaks: Can occur during surgery or afterwards if you fall. To fix these, you may require surgery.
