Dr. Lonnie Paulos is one of the leading orthopedic surgeons in this country. With over 30 years of experience, he can perform a Patellofemoral Knee Resurfacing and Replacement (PKRR). This is usually faster and easier than a total knee replacement.
Patients who have the best results from PKRR are those who have specific problems with their kneecap, patellar tracking or alignment problems, or patellar fracture. These conditions can lead to early wear of the cartilage under the kneecap.
If you have worsening arthritis in the other areas of your knee, you might want to consider how much resurfacing and replacing you want to do to avoid further damage and pain, allowing Dr. Paulos to replace the arthritic areas in other compartments of the knee as well within one surgery.
During surgery to perform a PKRR, Dr. Paulos creates a surface on the underside of the kneecap and the groove on the end of the thigh bone to accommodate the artificial joint. The artificial implant is shaped to glide easily beneath it and is called patellar resurfacing. With bone cement, the implanted joint is usually held in position. Dr. Paulos believes the most important part of surgery is to ensure that the kneecap is aligned correctly in the groove on the end of the thigh bone normally. If this is not carefully addressed, the newly implanted partial knee replacement could wear out prematurely. Recovery from PKRR will depend on the severity of the injury and the complexity of the procedure.
Rehabilitation plays a vital role in getting you back to your daily activities. You begin exercises to bend your knee immediately your procedure. While full weight can be placed on the knee, crutches or a walker are generally used for support for the first few weeks. As you increase your strength and flexibility, your rehabilitation will bring your leg back into normal and daily use.
