Jumper’s Knee Explained: Causes, Symptoms, and Treatment with Physiotherapy
What is Jumper’s Knee?
Jumper’s knee, medically known as patellar tendinitis, is a condition characterized by pain and inflammation in the patellar tendon, which connects the kneecap (patella) to the shinbone (tibia). This injury is common among athletes who engage in sports that involve frequent jumping, such as basketball, volleyball, and track and field.
Symptoms of Jumper’s Knee
Understanding the symptoms of jumper’s knee can help in early diagnosis and treatment. Common symptoms include:
- Pain: Sharp or aching pain in the front of the knee, particularly around the patellar tendon.
- Tenderness: Sensitivity to touch along the patellar tendon.
- Swelling: Mild to moderate swelling around the knee area.
- Stiffness: Reduced flexibility in the knee, especially after periods of rest.
- Weakness: Feeling of weakness or instability in the affected knee.
Causes and Risk Factors
Jumper’s knee is primarily caused by repetitive stress on the patellar tendon. Factors that can contribute to the development of this condition include:
- Overuse: Repeated jumping and landing activities increase stress on the patellar tendon.
- Poor Conditioning: Lack of proper warm-up, stretching, and conditioning can lead to tendon strain.
- Improper Technique: Incorrect jumping and landing techniques can exacerbate stress on the knee.
- Footwear: Wearing inappropriate shoes that do not provide adequate support can lead to knee injuries.
- Playing Surface: Hard and uneven surfaces can increase the impact on the knees during sports activities.
