Partial Knee Replacement
There are many advantages of partial knee replacements:
1. less pain
2. Lower infection rate
3. retain normal cartilage in the patellofemoral joint and lateral compartment
4. retain ACL which may allow for more normal knee kinematics
The Mirror knee system uses the patients tissues to guide the preparation of the knee for placement of the femoral component. This system creates a partial knee replacement that is balanced throughout the entire range of motion. This should lead to knee that feels more natural and should last longer.
Prior to your partial knee replacement, you will get X-rays of your knee. These X-rays will be used for preoperative Templating. This will provide your surgeon with a detailed view of your knee so a precise surgical plan with exact implant sizes can be determined.
Your surgery will be performed with a Minimally Invasive approach. The main tendon in the knee is preserved. The damaged bone ends are then removed from both the tibia (shin) and femur (thigh) to prepare for the artificial replacement. The replacement is then inserted and cemented into the bone. The cartilage in the patello-femoral joint and the lateral compartment of your knee are preserved. The soft tissue in the knee is then repaired with absorbable suture.
With the Rapid Recovery Program, surgery typically is done as out-patient.
Use of an assistive device, such as a walker, cane or crutches, may be required for several weeks post-surgery.
Most patients can resume driving approximately three weeks after the procedure if they feel safe and are off narcotics. Your doctor will discuss all of the restrictions of higher-impact activities that you will need to follow and for how long.
After surgery, most patients experience significant pain relief from their arthritis. You will be given pain medication to take as needed.
Physical therapy starts as soon as the day of surgery with the goal of strengthening the muscles and preventing scarring (contracture). Therapy begins with the patient sitting in a chair and progresses to stepping, walking and climbing stairs, first with crutches or walkers and then without supportive devices. Patients are encouraged to stand up and walk around as soon as they feel comfortable.
Total knee replacement is a very successful procedure. On average, replacement knee last 15-20 years. Some patients enjoy full use of the prosthesis after 25 years or longer and can participate in a wide range of activities that they were previously unable to enjoy while suffering from arthritis.
Risks associated with knee replacement are considered rare but can be serious. The risks and benefits of knee arthroplasty include, but are not limited to, infections (including severe sequelae), potential component failure, fracture, numbness, deep vein thrombosis, pulmonary embolus, nerve palsy, poor range of motion, the possibility of bone grafting, persistent pain, wound healing complications, progessive arthritis (if partial knee replacement), blood transfusions and death. These risks can be further reduced by choosing an experienced surgeon to perform your procedure, and by adhering to your surgeon's instructions before and after surgery.
These risks, along with any concerns you may have, will be discussed during a pre-surgical consultation to ensure that patients understand all aspects of their procedure and maintain realistic results for their total hip replacement.
Your surgeon can inform you as to whether you might be a good candidate for this type of surgery, as well as provide you with more information on its benefits and risks and answer any questions that may arise.
