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.
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. [4] The pain is generally in the front of the knee and comes on gradually. [2] [4] Pain may worsen with sitting down with a bent knee for long periods of time, excessive use, or climbing and ...
The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...
Running long distance can cause pain to the knee joint, as it is a high-impact exercise. [2] The location and severity of knee pain may vary, depending on the cause of the problem. Signs and symptoms that sometimes accompany knee pain include: [1] Swelling and stiffness; Redness and warmth to the touch; Weakness or instability; Popping or ...
Inflammation of the patellar tendon is present if the patellar tendon is painful upon palpation. Radiographic imaging should be done if the examination findings fulfills the Ottawa rules: age 55 years and older, pain at the head of fibula, patellar pain, unable to flex the knee to 90 degrees, and inability to stand and walk at least four steps.
The patella can also be fractured indirectly. For example, a sudden contraction of the quadriceps muscle in the knee can pull apart the patella. [1] Diagnosis is based on symptoms and confirmed with X-rays. [3] In children an MRI may be required. [3] Treatment may be with or without surgery, depending on the type of fracture. [2]
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]
Patella, its tendon and tibial tuberosity. The condition is usually seen in athletic individuals typically between 10 and 14 years of age. Following a strain or partial rupture of patellar ligament the patient develops a traction ‘tendinitis’ characterized by pain and point tenderness at the inferior (lower) pole of the patella associated with focal swelling.
