Patellar tendonitis is an injury that affects the tendon between the kneecap and tibia. The condition is most common in people who practice sports that involve frequent jumps (Basketball, soccer, volleyball). Because of this, the patellar tendonitis disease is also called “the jumper’s knee”. However, the patellar tendonitis disease can affect any person.
Tendon injuries range from patellar tendonitis (tendon inflammation) to tendon rupture. When the tendon is used excessively (dancing, cycling, running) the tendon stretches and becomes inflamed. Sudden movements such as the attempt to prevent a fall may cause excessive contraction of the quadriceps muscle above the patella with quadriceps tendon rupture or of the tendon below. This type of injury happens most likely in the elderly, whose tendons are weaker. Patellar tendonitis inflammation is sometimes called “jumper’s knee” because it occurs due to sports that require jumping, such as basketball, where muscle contraction and the force of falling to the ground after a jump create tendon tension. Tendon can become inflamed or tore after repeated stress.
