Patellar tendon rupture is a tear of the tendon that connects the knee cap (patella) to the tibia. [1] Often there is sudden onset of pain and walking is difficult. [1] In a complete rupture, the ability to extend that knee is decreased. [1] A pop may be felt when it occurs. [2]
Treatment typically involves rest and rehabilitation with a physical therapist. [6] Runners may need to switch to activities such as cycling or swimming. [3] Insoles may help some people. [3] Symptoms may last for years despite treatment. [3] Patellofemoral pain syndrome is the most common cause of knee pain, affecting more than 20% of young ...
The patella's posterior surface is covered with a layer of smooth cartilage, which the base of the femur normally glides smoothly against when the knee is bent. However, in some individuals the kneecap tends to rub against one side of the knee joint, irritating the cartilage and causing knee pain. [15]
"Knee pain often comes from muscular imbalance and improper form, so correcting those can reduce the pain," Gleason says. Calf strength is also important, Zaslow adds.
Also known as a broken kneecap, a patella fracture usually follows a history of trauma and commonly presents with swelling, pain, bruising and inability to both bend and straighten the knee. [5] The pain is worse when trying to stand and the person may be unable to walk. The pain can also be aggravated by prolonged periods of sitting.
Patellar tendinitis, also known as jumper's knee, is an overuse injury of the tendon that straightens the knee. [1] Symptoms include pain in the front of the knee. [1] Typically the pain and tenderness is at the lower part of the kneecap, though the upper part may also be affected. [2] Generally there is no pain when the person is at rest. [2]
Direct trauma to the knee displacing the patella is rare. [3] Displacement of the patella laterally out of its groove strains the medial stabilizing connective tissues, particularly the medial patellofemoral ligament (supporting 50–80% of the knee mechanisms in lateral patellar glide), which is torn usually at its femoral attachment. [3]
Elastic therapeutic tape, also called kinesiology tape or kinesiology therapeutic tape, Kinesio tape, k-tape, or KT [1] is an elastic cotton strip with an acrylic adhesive that is purported to ease pain and disability from athletic injuries and a variety of other physical disorders.
