Pain under kneecap

Pain when pressing below the kneecap is usually caused by sports injury, which is more common among teenagers. Although each of us needs to exercise every day to prevent the body from aging so easily, we also need to have certain skills when exercising. Don't exercise blindly. Here are some common sports injuries for you to prevent.

Several common sports injuries: ① Chronic minor injuries of muscles, tendons, and ligaments, including myofasciitis, tendon tenosynovitis, tendon and ligament insertion injuries, etc. Among them, the subtle injuries occurring at the tendon insertion are called "end disease", which is one of the most difficult sports insertion injuries to treat. They include rotator cuff injury, patellar tendon peritendinitis of the patellar tip type, and sciatic insertion injury of the hamstring muscle of the posterior thigh. Its pathological manifestations include tendon degeneration, ossification, and lip-like hyperplasia of the insertion.

② Articular cartilage injury, the main pathological manifestation of which is cartilage degeneration, such as patellar chondrosis, football ankle, throwing elbow, etc., more than 60% of which are caused by gradual strain, and a small part is caused by a single injury resulting in osteochondral fracture. This type of cartilage injury cannot repair itself after injury. Once damaged, it often leaves permanent changes and is difficult to treat. It is also the type of injury that most affects health, sports training, and sports lifespan. ③ Bone tissue strain, the most common of which are stress or fatigue periostitis and fractures, which can occur in the tibia and fibula, metatarsals, vertebral lamina, patella, navicular bone, talus, 1st and 2nd ribs, etc., among which the tibia and fibula are the most affected, followed by metatarsals and lamina. This type of injury can usually heal itself by changing training and reducing or stopping local load. However, attention should be paid to bird-beak fractures and navicular stress fractures occurring in the middle and lower 1/3 of the tibia. Once discovered, training must be stopped and fixed treatment must be performed.

④ Osteochondritis. In recent years, sports training has mostly started from children, and the occurrence of osteochondritis has attracted widespread attention in sports training. Common ones include vertebral osteitis, tibial tuberosity osteochondritis, distal radial epiphysisitis, humeral head, calcaneal epiphysisitis, etc. In addition, osteitis pubis and certain accessory bone injuries are also classified as osteochondritis according to their pathological changes. Most of these injuries affect training, and some affect development, and research on their prevention and treatment has also attracted attention. ⑤ Neurovascular injury. Chronic injuries include "punch drunkenness" (i.e. walking like a drunk, which is boxer's encephalomalacia), suprascapular nerve paralysis in volleyball players, anterior tibial compartment syndrome (march necrosis), etc. Sometimes we get injured accidentally while exercising. Some people may just apply medicine to relieve the pain and then don’t pay much attention to the injured area. In fact, we should pay attention to the injured part. Some injuries will become more and more serious if they are not fixed and treated in time.
