Below are some of the most common conditions impacting the knee, as described by the American Physical Therapy Association.

Patellofemoral Syndrome (runner's Knee)

Patellofemoral pain syndrome (PFPS) refers to pain at the front of the knee, in and around the kneecap (patella). PFPS is one of the most common types of knee pain experienced in the United States, particularly among athletes, active teenagers, older adults, and people who perform physical labor. Patellofemoral pain affects more women than men and accounts for 20% to 25% of all reported knee pain. Physical therapists design exercise and treatment programs for people experiencing PFPS to help them reduce their pain, restore normal movement, and avoid future injury.

Knee Replacement

A total knee replacement (TKR), also known as total knee arthroplasty, involves removing the arthritic parts of the bones at the knee joint (the tibia, sometimes called the shin bone; the femur, or thigh bone; and the patella, or kneecap) and replacing them with artificial parts. These parts consist of a metal cap at the end of the femur and a cemented piece of metal in the tibia with a plastic cap on it to allow the surfaces to move smoothly. When appropriate, the back part of the kneecap also may be replaced with a smooth plastic surface.

ACL Tear

An anterior cruciate ligament (ACL) tear is an injury to the knee commonly affecting athletes, such as soccer players, basketball players, skiers, and gymnasts. Nonathletes can also experience an ACL tear due to injury or accident. Approximately 200,000 ACL injuries are diagnosed in the United States each year. It is estimated that there are 95,000 ruptures of the ACL and 100,000 ACL reconstructions performed per year in the United States. Approximately 70% of ACL tears in sports are the result of noncontact injuries, and 30% are the result of direct contact (player-to-player, player-to-object). Women are more likely than men to experience an ACL tear. Physical therapists are trained to help individuals with ACL tears reduce pain and swelling, regain strength and movement, and return to desired activities.
