Knee

Meniscus surgery

The meniscus is an important shock-absorbing cartilage cushion in the knee. A healthy meniscus gives us the “bounce” in our step. Meniscus injury can occur from a variety of activities--from athletic trauma and falls to just “wearing out” with age. When our surgeons suspect a torn meniscus is the source of the patient’s pain, we will usually determine the size and shape of the meniscus tear with an MRI (magnetic resonance imaging). If the patient needs surgery to correct the torn meniscus, then arthroscopic minimally invasive knee surgery (“knee scope”) will usually be offered. Partial meniscus removal (“partial meniscectomy”) or meniscus repair will be performed based on the specific clinical situation. Often, patients will be allowed to bear full weight and walk right after surgery, and will return to light exercise within a month from surgery.

Ligament reconstruction

The ligaments are the “ropes” that hold our knee bones together. They are critical for keeping our knee stable and pain-free in many activities, from walking down the stairs to jumping for a rebound. The most commonly injured ligaments include the ACL (anterior cruciate ligament) and MCL (medial collateral ligament). While most ligament sprains can recover without surgery, those patients with a full ligament tear often will need a ligament reconstruction or repair procedure to return to their normal activities, including work and sports. Our fellowship-trained orthopedic surgeons specialize in the latest ligament reconstruction techniques, including “all-inside” ACL surgery and ACL repair. We partner with expert physical therapists in our community to ensure that patients receive the ideal rehabilitation program for a speedy return to their sport and activities.

Cartilage Restoration

Knee cartilage (“articular cartilage”) is the smooth white coating covering the ends of the bones in all of our joints. Having a thick, smooth cartilage surface in our knee joints is critical for walking and standing. Cartilage injuries most often occur from athletic activities and everyday trauma, such as tripping and falling, and are more common as we get older. Traditionally, patients with cartilage injuries have had very few options for restoring their cartilage back to normal. Our surgeons are equipped with the most well-studied cartilage repair procedures, including microfracture (biologic drilling), cartilage grafting (biologic cartilage repair), the OATS procedure (osteochondral allograft transplantation surgery), and osteotomy procedures to re-align the bone and joints. We know that deciding which surgery to have can be a difficult one, so our surgeons look forward to the opportunity to spend extra time with our cartilage patients to help them navigate this often complex process.

Partial Knee Replacement

Often called unicondylar knee replacement, a partial knee replacement is performed for patients who have “bone on bone” arthritis in only one area of their knee. Patient who have a partial knee replacement may have a faster and less painful recovery after surgery when compared to those who have a full knee replacement. The most common areas for partial knee replacement are the medial compartment (inside of the knee) and the patellofemoral compartment (under the kneecap). Our surgeons will help you decide whether a partial knee replacement or a full (total) knee replacement will be best for you. Partial knee replacement may be a great solution for some patients who have been told they are too young to have a total knee replacement.

Total Knee Replacement

One of the most successful and common orthopedic surgeries in the world is the full (total) knee replacement. This surgery is a game-changer for patients with severe knee arthritis who are living with pain and limitations. Our orthopedic surgeons perform a high volume of small incision, less invasive knee replacements using the most advanced implant surfaces, including newer ceramic and zirconium alloy implants. We take pride in using only knee replacement systems that have been on the market for many years (“battle-tested”) without product recalls or FDA (U.S. Food and Drug Administration) warnings. We partner with our hospital teams, including our surgical nurses, postoperative nurses, and physical therapists, to provide the patient with a comprehensive joint replacement program to make their recovery faster, easier, and safer.
