Anterior Cruciate Ligament ACL Reconstruction
The anterior cruciate ligament is one of the major stabilizing ligaments in the knee. It is a strong rope like structure located in the centre of the knee running from the femur to the tibia. When this ligament tears unfortunately it doesn't heal and often leads to the feeling of instability in the knee.
ACL reconstruction is a commonly performed surgical procedure and with recent advances in arthroscopic surgery can now be performed with minimal incisions and low complication rates.
Cartilage repair is a surgical grafting procedure that replaces damaged cartilage with healthy cartilage from a non‐weight bearing joint. Cartilage repair is performed to correct joint deformities and restore the weight‐bearing capability of the affected joint.

Meniscus tear is the commonest knee injury in athletes, especially those involved in contact sports. A sudden bend or twist in your knees causes meniscal tear. This is a traumatic meniscus tear. Elderly people are more prone to degenerative meniscal tears as the cartilage wears out and weakens with age. The two wedge-shape cartilage pieces present between the thighbone and the shinbone are called meniscus. They stabilize the knee joint and act as "shock absorbers".

Arthroscopy of the Knee Joint
Dr. Peterson is an expert in knee arthroscopy having received training from world-renowned knee surgeons at the Mayo Clinic. After he left Mayo, he completed a fellowship in Phoenix, Arizona dedicated to arthroscopy of the shoulder and knee. While there he developed expertise in treating knee conditions in a minimally-invasive, arthroscopic fashion. He has performed numerous ACL reconstructions arthroscopically and uses the most advanced techniques. Dr. Peterson is an expert in arthroscopic treatment of ACL tears, PCL tears, MCL&LCL injuries, cartilage restoration, microfracture, OATS, and meniscus repair. He is also the only surgeon in the region to perform an arthroscopic procedure for knee cap arthritis called the arthroscopic lateral facetectomy which can be an alternative to joint replacement for select patients.

Total Knee Replacement (TKR)
Dr. Peterson's training at the Mayo Clinic included extensive experience in knee replacement. He uses minimally invasive techniques during partial and total knee replacement that utilize smaller incisions and spare the quadriceps muscle which is the main thigh muscle responsible for walking. This approach is called the quad-sparing subvastus approach. The main advantage is less postoperative pain, quicker recovery, and less time that you will need to use crutches/canes. Most patients are candidates for this approach. Dr. Peterson also uses the latest technology and state-of-the-art implants to maximize your function and increase lifespan of the prosthesis. Dr. Peterson's knee replacement procedures include Total knee replacement, Uni knee replacement, Patellofemoral replacement, and Revision knee replacement.

Uni Condylar Knee Replacement
This simply means that only a part of the knee joint is replaced through a smaller incision than would normally be used for a total knee replacement. The knee joint is made up of 3 compartments, the patellofemoral and medial and lateral compartments between the femur and tibia (i.e. the long bones of the leg). Often only one of these compartments wears out, usually the medial one. If you have symptoms and X-ray findings suggestive of this then you may be suitable for this procedure.

This means that part or all of your previous knee replacement needs to be revised. This operation varies from very minor adjustments to massive operations replacing significant amounts of bone and hence is difficult to describe in full.
