Runner's Knee

	Runner's Knee Runner's knee may refer to a number of overuse injuries involving pain around the kneecap (patella), such as: Patellofemoral pain syndrome Chondromalacia patellae Iliotibial band syndrome Plica syndrome Plica syndrome is a condition that occurs when a ''plica'' (a vestigial extension of the protective synovial capsule of usually the knee) becomes irritated, enlarged, or inflamed. Cause This inflammation is typically caused by the plica being ca ... {{Set index article Knee injuries and disorders ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Patellofemoral Pain Syndrome Patellofemoral pain syndrome (PFPS; not to be confused with jumper's knee) is knee pain as a result of problems between the kneecap and the femur. The pain is generally in the front of the knee and comes on gradually. Pain may worsen with sitting, excessive use, or climbing and descending stairs. While the exact cause is unclear, it is believed to be due to overuse. Risk factors include trauma, increased training, and a weak quadriceps muscle. It is particularly common among runners. The diagnosis is generally based on the symptoms and examination. If pushing the kneecap into the femur increases the pain, the diagnosis is more likely. Treatment typically involves rest and rehabilitation with a Physical Therapist. Runners may need to switch to activities such as cycling or swimming. Insoles may help some people. Symptoms may last for years despite treatment. Patellofemoral pain syndrome is the most common cause of knee pain, affecting more than 20% of young adults. It occurs ...

	Chondromalacia Patellae Chondromalacia patellae (also known as CMP) is an inflammation of the underside of the patella and softening of the cartilage. The cartilage under the kneecap is a natural shock absorber, and overuse, injury, and many other factors can cause increased deterioration and breakdown of the cartilage. The cartilage is no longer smooth and therefore movement and use is very painful. While it often affects young individuals engaged in active sports, it also afflicts older adults who overwork their knees. ''Chondromalacia patellae'' is sometimes used synonymously with patellofemoral pain syndrome. However, there is general consensus that ''patellofemoral pain syndrome'' applies only to individuals without cartilage damage. This condition is also known as Chondrosis. The term literally translates to softening (malakia) of cartilage (chondros) behind patella in Greek. Cause The condition may result from acute injury to the patella or chronic friction between the patella and a groove in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Iliotibial Band Syndrome Iliotibial band syndrome (ITBS) is the second most common knee injury, and is caused by inflammation located on the lateral aspect of the knee due to friction between the iliotibial band and the lateral epicondyle of the femur. Pain is felt most commonly on the lateral aspect of the knee and is most intensive at 30 degrees of knee flexion. Risk factors in women include increased hip adduction and knee internal rotation. Risk factors seen in men are increased hip internal rotation and knee adduction. ITB syndrome is most associated with long-distance running, cycling, weight-lifting, and with military training. Signs and symptoms ITBS symptoms range from a stinging sensation just above the knee and outside of the knee (lateral side of the knee) joint, to swelling or thickening of the tissue in the area where the band moves over the femur. The stinging sensation just above the knee joint is felt on the outside of the knee or along the entire length of the iliotibial band. Pain may ...

	Plica Syndrome Plica syndrome is a condition that occurs when a ''plica'' (a vestigial extension of the protective synovial capsule of usually the knee) becomes irritated, enlarged, or inflamed. Cause This inflammation is typically caused by the plica being caught on the femur, or pinched between the femur and the patella. The most common location of plica tissue is along the medial (inside) side of the knee. The plica can tether the patella to the femur, be located between the femur and patella, or be located along the femoral condyle. If the plica tethers the patella to the femoral condyle, the symptoms may cause it to be mistaken for chondromalacia. The plica themselves are remnants of the fetal stage of development where the knee is divided into three compartments. The plica normally diminish in size during the second trimester of fetal development, as the three compartments develop into the synovial capsule. In adults, they normally exist as sleeves of tissue called synovial folds. The p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
