What is Jumper's Knee/Patellar Tendonitis?

Jumper's knee, also known as patellar tendinopathy or patellar tendinitis, is a condition characterized by pain and inflammation in the patellar tendon, which connects the kneecap (patella) to the shinbone (tibia). This condition is commonly seen in athletes, particularly those involved in activities that require repetitive jumping and landing, such as basketball or volleyball. However, it can also occur in individuals engaged in other sports or activities that involve frequent, intense leg movements.

Key features of jumper's knee include:

1. Pain below the kneecap: The primary symptom is pain, often located just below the kneecap. The pain may be gradual in onset and worsen with activities that involve jumping, running, or kneeling.

2. Tenderness: The area around the patellar tendon may be tender to the touch.

3. Stiffness and swelling: Some individuals with jumper's knee may experience stiffness and swelling around the knee.

Jumper's knee is considered an overuse injury, where repetitive stress on the patellar tendon leads to microscopic tears and inflammation. Factors contributing to the development of jumper's knee include:

• Repetitive jumping: Activities like jumping and landing put significant strain on the patellar tendon.

• Muscle imbalances: Weakness or imbalances in the quadriceps and hamstring muscles can contribute to increased stress on the patellar tendon.

• Training errors: Rapid increases in the intensity or duration of physical activity without proper conditioning and rest can contribute to overuse injuries.
