ACL Injury

An anterior cruciate ligament (ACL) injury is one of the most common knee injuries, resulting in a tear in the ACL ligament. The ACL ligament is one of four ligaments in the knee that keeps the joint stable and connects the thighbone to the tibia.

Arthritis in the Knee

Arthritis in the knee is inflammation in the knee joint. Although there are more than 100 different forms of arthritis, arthritis in the knee is most commonly caused by osteoarthritis with the cartilage gradually wearing away until the bones rub on bones.

Hamstring Tear or Strain

A hamstring tear or strain, also called a pulled hamstring, is an injury to one of the back muscles in the back of the thigh. These injuries are common with athletes who participate in sports where they must sprint.

Iliotibial Band Syndrome

Iliotibial band syndrome (IT band syndrome or ITBS) occurs when the ilio-tibial band (IT band), the ligament that runs along the outside of the leg from hip down to the shin, becomes tight, painful and inflamed.

Knee Bursitis

Knee bursitis occurs when the bursa (fluid-filled sacs) in or around the knee joint become inflamed. Symptoms of knee bursitis are pain and limited mobility. Bursitis in the knee is also called pes anserine bursitis.

Dislocated Knee

A knee dislocation occurs when the tibia and fibula (bones of the lower leg) are moved in relation to the femur (thigh bone). The bones are held together with ligaments (strong connective bands of tissue). When the knee dislocates, the ligament tears.

Knee Fracture

A knee fracture is called a patellar fracture. A patellar fracture is a break in the kneecap (patella). The kneecap is susceptible to fracture if you fall directly on the knee or sustain some other direct trauma to the patella.

Knee Strain or Sprain

A knee strain occurs when a muscle or tendon is torn or stretched. A knee sprain occurs when the ligaments, ACL, LCL, MCL and PCL, in the knee joint stretch or tear.

LCL Injury

A LCL injury occurs when there is a tear to the lateral collateral ligament (the ligament on the outside of the knee that runs from the thighbone to the lower-leg bone). The LCL’s function is to keep the outer aspect of the knee joint stable.

MCL Injury

A medial collateral ligament injury (commonly referred to as an MCL injury) is a tear or sprain to the medial collateral ligament. The MCL is located on the inner side of the knee but outside the joint.

Meniscus Tear or Strain

A meniscus tear or strain occurs when the meniscus (two pieces of cartilage that act as a cushion between the thigh bone and shin bone) is injured. Meniscus tears are a common injury to the knee.

Tendonitis in the Knee

Patellar tendonitis, tendonitis in the knee, is inflammation in the tendon that connects the kneecap (patella) to the shinbone (tibia). It is also called “jumper’s knee.” Tendonitis in the knee develops from repetitive stress on the knees.

Patellar Tracking Disorder

Patellar tracking disorder is a condition where the kneecap moves out of place when the leg straightens or bends. In most cases, the kneecap moves to the outside of the leg, but there are cases where the kneecap moves toward the inside of the leg.

Patellofemoral Pain Syndrome

Patellofemoral pain syndrome is a knee condition used to describe pain in the front of the knee and around the patella or kneecap. This knee condition occurs when the cartilage is worn down or roughened.

Learn More

PCL Injury

A posterior cruciate ligament (PCL) injury occurs when the posterior cruciate ligament, ligament in the back of the knee that connects the thighbone (femur) to the shinbone (tibia), tears due to powerful force to the back of the knee.

Piriformis Syndrome

Piriformis syndrome is a medical condition that causes pain and spasms in the buttocks. Often, the piriformis muscle aggravates or constricts the sciatic nerve and causes tingling, numbness and pain down the back of the leg to the foot.

Quadriceps Tear or Strain

A quadriceps tendon tear or strain is an injury to the tendon that works with the muscles in the front of the leg to straighten the leg. Although they are not common, it can make it difficult to walk or participate in day-to-day activities.

Learn More

Quadriceps Tendonitis

Quadriceps tendonitis is inflammation in the quadriceps muscle and tendon that is caused by overuse or alignment problems in the knee structures. Tendonitis in the lower extremity can affect the knee, hip, quadriceps or ankle.

Learn More

Thigh or Calf Strain

A thigh or calf strain occurs when a muscle or tendon is torn or stretched. The tendons are fibrous cords that connect muscles to bones. A thigh or calf sprain occurs when a ligament in the thigh or calf is stretched or torn.

Learn More

Thigh and Lower Leg Fractures

A thigh, femur shaft, fracture occurs when the thighbone (the longest, strongest bone in the body) breaks. ​A lower leg fracture is a break in the tibia (shinbone). A tibia fracture, shinbone fracture, is the most commonly broken bone in the body.

Compartment Syndrome

Compartment syndrome is increased pressure within an enclosed space of the body as a result of trauma or swelling. As a result of the increased pressure, the blood supply to nerves and muscles may be restricted.
