What is Patellofemoral Knee Replacement?
Arthritis in only one compartment of the knee may be treated by partial knee replacement surgery. A Patellofemoral knee replacement is a minimally invasive surgical option performed in the patellofemoral compartment only, preserving the knee parts not damaged by arthritis as well as the stabilizing anterior and posterior cruciate ligaments (ACL and PCL).
The smaller implants used with a partial knee replacement surgery are sized to your anatomy. Patellofemoral knee arthroplasty surgery will not alter your ability to eventually move to a total knee replacement in the future should that become necessary.
Compartments of the Knee
The knee can be divided into three compartments: patellofemoral (the compartment in front of the knee between the kneecap and thighbone), the medial compartment (on the inside portion of the knee), and lateral compartment which is the area on the outside portion of the knee joint.
Indications for a Patellofemoral Knee Replacement
Patellofemoral knee replacement surgery may be recommended by Mr Ghosh if you have not obtained adequate relief with conservative treatment options. This less invasive bone and ligament preserving surgery is especially useful if you are young and active as the implant closely mimics the actual knee mechanics when compared to total knee surgery.
Patellofemoral Knee Replacement Procedure
Patellofemoral knee replacement surgery is performed under general anaesthesia or spinal anaesthesia with sedation. Your surgeon makes a small incision, about 3-4-inches long over your knee. 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 that 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 your surgeon is satisfied with the results, the surgical instruments are removed and the incisions closed carefully and covered with a sterile dressing.
Postoperative Recovery after Patellofemoral Knee Replacement
You will be taken to the recovery room and monitored for any complications. You will be given pain medication to keep you comfortable. You will need someone to drive you home due to the drowsy effects of the anaesthesia. Swelling is normal after knee surgery. Ice, compression, and elevation of the knee will help minimize swelling and pain.
You will be given specific instructions regarding the activity. Usually, there are a 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 of Patellofemoral Knee Replacement
As with any major surgery, there are potential risks involved with patellofemoral knee replacement. The decision to proceed with the surgery is made because the advantages of surgery outweigh the potential disadvantages. Some of the possible complications include:
- Allergic reactions to medications
- Blood loss requiring transfusion with its low risk of disease transmission
- Heart attacks, strokes, kidney failure, pneumonia, bladder infections
- Complications from nerve blocks such as infection or nerve damage
- Deep vein thrombosis
- Ligament injuries
- Injury to blood vessels or nerves
- Arthrofibrosis (stiffness)
- Wearing out of the prosthesis
- Dislocations and fractures
Risk factors that can negatively affect adequate healing after knee arthroscopy include:
- Poor nutrition
- Age (over 60)
- Chronic Illness
- Steroid Use
