![]() This is inflammation of a growth plate just below the knee where the patellar tendon attaches to the shinbone. It produces a burning sensation just below the kneecap. This is caused by over-stretching or putting extra stress on the patellar tendon at the front of the knee. This produces severe pain and swelling at the front of the knee. Twisting or trauma could cause the kneecap to move out of the groove in the thigh bone. If this does not happen, the cartilage on the two surfaces may wear away and the bones come into contact with each other causing pain due to arthritis. The kneecap should track smoothly in the groove on the lower end of the thigh bone. It is caused by the softening and deterioration of the cartilage on the underside of the kneecap or a loose flap of cartilage. Patella ChondromalaciaĪ grating feeling and pain at the junction of the thigh and kneecap may be patella chondromalacia. Various causes including overuse or misalignment of the kneecap. This is a general term used for a dull pain in the vicinity of the kneecap and front of the knee. Symptoms include pain, possible “popping” sound, swelling and instability. It is the most common form of sports injury. Damage occurs due to twisting, over extension or sudden force through the knee. The ACL runs through the knee, gives it stability and controls back and forward movement. Possible Causes of Pain Anterior Cruciate Ligament (ACL) This includes pain at the front and within the knee. It is also associated with arthritis and gout. If not treated early or correctly the synovial membrane becomes thickened with more blood vessels and becomes swollen and painful. It is caused by overuse or trauma and results in repeated bleeds into the joint. If this membrane becomes inflamed it is called synovitis. The knee is a synovial hinge joint, and as such the joint is lined with a synovial membrane. The condition is often apparent during repetitive exercise such as climbing stairs. The reason for this is improper tracking, poor alignment or dislocation of the kneecap. It is caused by increased pressure on the lateral facet of the patella. This refers to dull aching pain underneath, around the sides or below kneecap. When a plica becomes inflamed, perhaps because of repetitive knee movement, trauma or twisting, it causes pain and weakness in the knee. About 50% of the population is thought to have the remains of the embryonic plicae. There were four of these folds in the knee joint originally, but they often become absorbed during foetal development. Plica SyndromeĪ plica is the fold in the thin synovial membrane that lines the knee joint. When the articular cartilage covering the surfaces of the bone wears away and becomes inflamed the bones come into contact with each other resulting in pain. This affects the underside of the kneecap (patella) and the trochlear groove in the femur in which it moves. Possible Causes of Pain Quadriceps tendonitis – this is caused by the irritation, strain or injury to the quadriceps tendon. This is the location of the quadriceps tendon which attaches the four large muscles of the front of the thigh to the knee cap. The diagram, below, is a handy guide to the possible reasons for your pain. You may be experiencing knee pain and want to know the possible causes. Knee pain could be the result of a problem with any one of these components, or a combination of several. The knee is a complex structure consisting of bone, cartilage, muscle, tendon, ligament, synovial fluid and nerves. However, apart from being the largest hinge joint in the body, it is also unusual in that it has a degree of rotational movement. Technically the knee is a synovial hinge joint, meaning that it is supplied with synovial fluid to lubricate movement and nourish the joint, and also moves forward and backwards like a hinge. Knee pain can vary in degree from being something which is a minor irritation or which causes slight concern to being a major problem impacting on your mobility and way of life. 31st December 2019 Knee Pain Location Chart By Mr. ![]()
