Therefore, the quadriceps tendon and patellar tendon have a role like a pulley, when the quadriceps muscle contracts, the patellar tendon is stretched, making it easy for people to stretch the knee.
However, patellar tendon can also be ruptured, the cause of patellar tendon rupture is usually due to direct trauma to the knee or sudden knee flexion during sports or daily activities. In addition to traumatic causes, some musculoskeletal conditions can cause the patellar tendon to lose its strength, leading to rupture. Some of the causes are:
Patellar tendinitis : Patellar tendonitis is mainly caused by repetitive movements or can be caused by corticosteroid injections directly or around the patellar tendon, which increases the risk of tearing the patellar tendon. higher tea. Chronic diseases: Chronic diseases such as chronic kidney failure, rheumatoid arthritis, diabetes, infections, metabolic diseases can lead to poor blood supply, thereby weakening the patellar tendon. and break easily.
