Believe it or not, not all knee replacements were designed to be round! Dr. Peterson uses the Stryker Single-Radius “Round” Knee Replacement because he believes that his patients benefit from the improved knee stability and strength that comes from this particular design of implant.

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.
Hip Replacement
New Hip Replacement Technology
Dr. Peterson received extensive training in hip replacement while at the Mayo Clinic. He uses minimally invasive techniques including smaller incisions and muscle sparing approaches. His approach is called the Mini-Posterior approach. This approach enters the hip joint through the capsule in the back of the joint and avoids cutting the main hip abductor muscles which are responsible for walking without a limp. The main advantage of this approach is less postop pain, quicker recovery, and less need for crutch/cane. Also their is a much higher chance of walking without a limp after surgery than the traditional anterior muscle splitting approach. Dr. Peterson uses the latest technology and state-of-the art implants and technology to enhance your outcome following surgery. Dr. Peterson's hip procedures include Total hip replacement, Mobile Bearing Hip Replacement.
Dr. Peterson is the first surgeon in the region to use the latest technological advancement in total hip replacement; The Dual Mobility MDM hip replacement from Stryker. This incorporates the use of two balls instead of one. An inner ball made of ceramic or metal, and an outer X3 highly crosslinked polethylene ball. This unique bearing has the advantage of greatly increased stability compared with conventional hip replacement. A recent study that reviewed the current literature showed the dislocation rate to be only 0.1% with dual mobility hips versus 2-7% for traditional hip replacement. (MA Mont '12) The wear rate is also significantly reduced making this a very attractive implant for younger active patients. Note in the video below how both femoral heads move independently of each other and allow greater range of motion than could be accomplished with just one.
Dr. Peterson specializes in shoulder surgery. He has trained with multiple, world-renowned shoulder surgeons. Many shoulder conditions can be treated all arthroscopically, however, shoulder arthritis usually needs to be treated with replacement. Dr. Peterson's performs Total shoulder replacement, Reverse shoulder replacement, and Copeland humeral hemi-resurfacing. One of the major recent advances in shoulder replacement includes the use of the Reverse replacement. This implant is for patients with arthritis and a massive, non-repairable rotator cuff tear. This is a condition that up until a few years ago, no good surgical option existed. Dr. Peterson says "The results can be nothing short of amazing." He is proud to have trained at the Mayo Clinic with the surgeons who designed the prosthesis that he uses.
