Specialty Area: Knee
Anterior Cruciate Ligament Tear (ACL Tear)
This injury is a tearing of the ACL ligament in the knee joint. The ACL ligament is one of the bands of tissue that connects the femur to the tibia. An ACL tear can be painful. It can cause the knee to become unstable.
Articular Cartilage Injury
Articular cartilage injuries can occur as a result of either traumatic mechanical destruction, or progressive mechanical degeneration (wear and tear). With mechanical destruction, a direct blow or other trauma can injure the articular cartilage.
Avascular Necrosis (Osteonecrosis) of the Knee
This condition occurs when a bone’s normal blood supply is disrupted. The affected bone cells die and the dead bone weakens. The bone may begin to fracture and collapse, leading to arthritis.
Hamstring Muscle Injuries
The hamstrings are three powerful muscles that travel along the back of your thigh. They are the semitendinosus, the semimembranosus and the biceps femoris muscles. They help bend your knee and extend your leg behind your body. Because these muscles handle high loads of stress, they are susceptible to stretching and tearing. This is called a muscle “strain.” Hamstring strains are common among runners, dancers, and athletes who play sports that require sudden starts and stops.
Iliotibial Band Syndrome (ITBS)
This is a problem on the outer side of your thigh. It’s an inflammation of the iliotibial band. That’s a thick band of tissue that spans from your hip to your shinbone. When this band becomes in inflamed, it can hurt.
Lateral Collateral Ligament (LCL) Injury
This is a stretching or tearing of a ligament on the outer side of your knee. The lateral collateral ligament, commonly called the “LCL”, connects the femur to the fibula. The LCL helps stabilize your knee. This ligament, along with the medial collateral ligament, helps prevent excessive side-to-side movement of your knee joint. It helps keep the upper and lower leg aligned properly.
Medial Collateral Ligament (MCL) Injury
This is a stretching or tearing of a ligament on the inner side of your knee. The medial collateral ligament, commonly called the “MCL”, is connected to the femur and to the tibia. The MCL helps stabilize your knee. This ligament, along with the lateral collateral ligament, helps prevent excessive side-to-side movement of your knee joint. It helps keep the upper and lower leg aligned properly.
This is a common injury of the knee. Your knee joint is cushioned by two c-shaped wedges of cartilage called the “menisci.” Each individual cushion is called a “meniscus.” This injury is a tear of one of these cushions.
This is a type of injury that causes knee pain in children. It’s an inflammation of a growth plate in the tibia. Growth plates are places where new bone tissue forms. They are found in the long bones of growing children. But growth plates are weaker than the surrounding bone. That makes them easier to injure.
Osteoarthritis of the Knee
Knee pain may keep you from being as active as you like. And it may come from a gradual breakdown of your knee’s cartilage. That’s a protective tissue on the ends of your bones. In a healthy knee, the bones glide smoothly against each other. But in a knee with osteoarthritis, cartilage begins to wear away. Bone rubs against bone. Bony bumps we call “bone spurs” may form.
Osteochondritis Dissecans of the Knee
This condition is characterized by the death of an area of cartilage and bone in the knee joint. The dead section may remain in place, forming a lesion, or it may loosen and partially detach from the surrounding bone. It may break away completely and float around inside the joint.
Patellar Tracking Disorder
This is a problem with the alignment of the patella (the bone at the front of the knee, commonly called the “kneecap”). With this disorder, the patella shifts out of its normal track as you bend or extend your knee.
Patellofemoral Pain Syndrome
This is a pain you feel in the front of your knee. It involves the patella. That’s the bone we commonly call the “kneecap.” The patella slides up and down in a groove on your femur as you bend and extend your knee. If you have this syndrome, you may have injured the soft tissues that support and cushion your kneecap. Or, you may have some damage to the cartilage on the underside of the kneecap.
Posterior Cruciate Ligament (PCL) Injuries
Strong bands of tissue called “ligaments” help stabilize the bones that form the knee joint. One of these ligaments is called the “PCL.” It helps connect the femur to the tibia. If you stretch or tear a PCl, your knee may become unstable.
Tibial Spine Fracture
This fracture happens in the center of the knee, between two cushions of cartilage known as the “menisci.” It involves a bony protrusion we call the “tibial spine.” It’s where the anterior cruciate ligament (commonly called the “ACL”) attaches to the tibia. A tibial spine fracture can cause the knee to become unstable.
ACL Reconstruction (Arthrex® TightRope®)
The anterior cruciate ligament, commonly called the ACL, is one of the ligaments that connects the femur to the tibia. During this procedure, a damaged ACL is replaced with a graft. The surgeon performs this procedure with the aid of an arthroscopic camera.
ACL Reconstruction (Patellar Tendon Graft Technique)
This procedure repairs your knee after a tear of the anterior cruciate ligament (commonly called the “ACL”). This ligament is in the center of the knee. It helps anchor the femur to the tibia. This surgery can allow you to regain normal knee function.
Articular Cartilage Restoration
This repairs damaged articular cartilage in your knee. That’s a type of cartilage that covers and protects the ends of your bones. Repairing it helps you stay active.
Cartilage Repair, Arthroscopically-Assisted Technique (Zimmer® DeNovo® NT Natural Tissue Graft)
This procedure repairs damaged articular cartilage. This is the cartilage that covers and protects the ends of your bones where they meet in your body’s joints. When this cartilage is damaged, bone can rub painfully against bone. With this technique, a patch of cartilage cells is used to repair the damage.
Lateral Release and Medial Imbrication
This procedure is designed to loosen or tighten ligaments on either side of the patella (kneecap) to improve the movement of the patella in patients suffering from patellar tracking disorder. This procedure is usually performed arthroscopically through one or two small incisions near the patella.
MACI® (Autologous Cultured Chondrocytes on a Porcine Collagen Membrane)
This repairs damaged articular cartilage in your knee. That’s a type of cartilage that covers and protects the ends of your bones. Damaged articular cartilage will not heal on its own. Repairing it helps you stay active. MACI is a two-step procedure. This means you’ll have two procedures a few weeks apart.
This outpatient procedure is performed to replace lost or severely damaged meniscal cartilage in the knee joint. In a healthy knee, this cartilage is present in two c-shaped wedges called menisci. Each one is called a meniscus. These wedges help cushion and stabilize the knee. This procedure is performed under general anesthesia with the aid of a small camera, called an arthroscope, and miniature instruments.
Meniscus Repair (Arthroscopic Technique)
Each of your knee joints is cushioned by two c-shaped wedges of cartilage. The two cushions in each knee are called the “menisci.” Individually, each cushion is called a “meniscus.” Certain motions, such as twisting the knee, can cause a meniscus to tear. In many cases, a torn meniscus can be treated with arthroscopic surgery.
Microfracture Drilling Procedure for Isolated Chondral Defect
This minimally-invasive procedure repairs damaged cartilage in the knee joint. Small holes are drilled into the bone at the base of the damaged area to stimulate the growth of healthy “scar” cartilage.
Mini Incision Total Knee Replacement
Mini-incision Total Knee Arthroplasty, also called MIS TKA, replaces the damaged and painful areas of the knee joint with metal and polyethylene plastic parts. The MIS total knee procedure is performed through an incision that is smaller than the incision used for traditional total knee replacement surgery. This technique reduces blood loss and pain and allows for a shorter recovery.
The meniscus is a cushion of cartilage. There are two in each knee. If one of these shock absorbers is worn out or hurt, you may need a partial meniscectomy to remove the damaged areas.
This surgical procedure removes portions of damaged cartilage on the femur in the knee joint that have been rubbing against the underside of the patella, causing pain and loss of mobility. This cartilage is then replaced with a specially-designed implant.
Posterior Cruciate Ligament (PCL) Reconstruction
This surgical procedure replaces a damaged posterior cruciate ligament (PCL). The PCL is a band of tissue that connects the femur to the tibia inside the knee.
PRP Therapy (Overview) (AcCELLerated Biologics)
Platelet rich plasma therapy can help injured joints and other problems. It uses parts of your own blood to reduce pain and speed up healing.
Stem Cell Therapy (Overview)
If you have an injury, or if you have tendons or ligaments that have become inflamed, stem cell therapy may help. It uses your body’s own stem cells to help heal damage. It may help you avoid surgery.
Stem Cell Therapy for Knee Pain
If you have injured your knee, or if normal wear and tear has caused degeneration of your joint, stem cell therapy may help. It uses parts of your own blood to help repair knee damage. It may help you avoid surgery.
Tibial Tubercle Osteotomy
This procedure, also called bone realignment, is designed to improve the movement of the patella (the kneecap) to correct patellar tracking disorder. The procedure usually requires hospitalization and general anesthesia.
Total Knee Replacement
This procedure restores function to a severely damaged knee. Most commonly, it is used to repair a knee that has been damaged by arthritis. During the procedure, the surgeon replaces the damaged portions of the knee with artificial parts. These parts consist of a metal femoral component, a metal tibial component and a plastic spacer. A small plastic patellar component may also be used.
