Conditions

  • Anatomy of the Knee

    The knee connects the upper leg bone to the lower leg bone. Cartilage covers the ends of both leg bones and the underside of the patella, or knee cap. When these surfaces are smooth, the joint glides easily and without pain.

  • Anterior Cruciate Ligament (ACL) Injuries in Women

    The anterior cruciate ligament, commonly called the ACL, is a thick, elastic band of tissue that runs from the bottom of the femur to the top of the tibia. It helps stabilize the knee joint. The ACL can become stretched or torn when the knee is twisted or hyperextended. For reasons that are not fully […]

  • 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.

  • 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.

  • Deep Vein Thrombosis (DVT)

    This condition is a blood clot that forms in a vein deep inside the body. This type of clot most commonly develops in the legs. This condition is dangerous, because the clot can break free and travel through the bloodstream to the lungs.

  • Fractures of the Tibial Spine

    This condition is a fracture of a portion of the tibia, also called the shin bone, in the knee joint. The tibial spine is a specialized ridge of bone in the tibia where the anterior cruciate ligament (ACL) attaches. This ligament is important in maintaining flexibility and stability in the knee.

  • Goosefoot (Pes Anserine) Bursitis of the Knee

    This condition is an inflammation of the pes anserine bursa, a fluid-filled sac between the tibia and the tendons of the hamstring muscle on the inner side of the knee. It can cause pain and restrict motion of the knee.

  • Iliotibial Band Syndrome (ITBS)

    This condition is a painful inflammation of the iliotibial band, a thick, tendon-like portion of a muscle that travels from the hip down the outer side of the thigh to the knee. ITBS results in pain, aggravated by activity, that is usually felt on the outer side of the knee.

  • Meniscus Tears

    The meniscus is comprised of two c-shaped wedges of cartilage that cushion and stabilize the knee joint. A torn meniscus can cause pain and limited mobility in the knee.

  • Osgood-Schlatter Disease

    This overuse injury is an inflammation that occurs at the point where the patellar tendon attaches to the tibia. It most commonly affects adolescents. One or both knees may be affected.

  • Osteoarthritis of the Knee

    Osteoarthritis, also called degenerative arthritis, is a gradual breakdown of cartilage in the joints. Cartilage is a tough, flexible connective tissue that protects the ends of bones in the joints. Osteoarthritis is common in the knees because the knees bear the weight of the body. Osteoarthritis of the knee can severely impact a person’s lifestyle.

  • 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.

  • Osteomyelitis

    This condition is an infection of the bone cells or the bone marrow that can lead to death of the bone tissue. If not treated properly, it can spread from the original site of infection to other parts of the body. In adults, osteomyelitis commonly affects the spine, pelvis and feet. In children, it commonly […]

  • Patella Fracture (Broken Knee Cap)

    This condition is a crack or fracture of the patella, the bone on the front of the knee that covers the knee joint. The patella helps to protect the joint as well as provide strength and stability.

  • Patella Tendon Rupture

    This condition occurs when the tendon that holds the patella, (the knee cap), to the tibia tears and splits apart, allowing the patella to slide upward. This causes pain and an inability to straighten the knee.

  • Patellar Tendonitis (Jumper’s Knee)

    This condition is an inflammation of the tendon that connects the patella (the kneecap) to the tibia in the knee joint. This tendon is part of the structure of muscles and tendons in the knee that allows the knee to straighten from being bent.

  • Patellar Tracking Disorder

    The patella (kneecap) is held in place by the quadriceps and patellar tendons. Ligaments on either side also help stabilize the patella. Patellar tracking disorder is a painful condition caused by a problem with the bones, muscles or ligaments around the patella.

  • Patellofemoral Pain Syndrome (Runner’s Knee)

    This condition is an irritation of the cartilage on the back of the patella (the kneecap) that causes pain in one or both knees.

  • Prepatellar Bursitis (Kneecap Bursitis)

    This condition is an inflammation of the prepatellar bursa, a fluid-filled sac that covers the front of the kneecap. Prepatellar bursitis results in pain and swelling at the front of the knee.

  • Quadriceps Tendon Tear

    This condition is a tear of the tendon that connects the patella to the quadriceps muscles of the thigh. The quadriceps muscle is used to straighten the leg from the bent position. A complete rupture of the quadriceps tendon is a disabling injury.

  • Septic Arthritis of the Knee

    This condition occurs when harmful bacteria infect the knee joint, causing pain and swelling, and damaging the healthy tissues in the joint. Any joint in the body can become infected, but the knee is the most common.

  • Supracondylar Femoral Fracture

    This condition is a break in the femur at the knee joint. The fracture can range from a small crack to a full break that allows part of the bone to separate. This injury can involve the cartilage on the base of the femur in the knee joint, and may increase the risk of developing […]

  • Tibial Fractures

    This condition is a break in the shin bone, called the tibia. A tibial fracture can occur anywhere along the bone, and can range from small cracks to a full break that allows the bone to separate.

  • Tibial Plateau Fracture

    This condition is a fracture at the top of the tibia, also called the shin bone. This fracture usually involves both bone and cartilage, so there is a high risk of developing arthritis from injury to the cartilage cells.

  • Torn Posterior Cruciate Ligament (PCL)

    This condition occurs when the posterior cruciate ligament (PCL), a band of tissue that connects the femur to the tibia inside the knee joint, becomes torn or worn away. A torn PCL causes pain and instability of the knee.
