Patellar Tendinitis: A Common Knee Injury

Patellar tendinitis, also known as jumper’s knee, is a common overuse injury that affects the tendon connecting the kneecap (patella) to the shinbone (tibia). This tendon, known as the patellar tendon, plays a crucial role in extending the knee. When this tendon becomes inflamed or irritated, it can cause pain and discomfort.

Common Causes of Patellar Tendinitis

Patellar tendinitis often occurs due to repetitive stress on the knee joint. Some common factors that can contribute to this condition include:

  • Overuse: Athletes involved in jumping sports, such as golf, pickleball, basketball, volleyball, and tennis, are particularly prone to patellar tendinitis. Repeated jumping and landing can put excessive strain on the patellar tendon.
  • Poor biomechanics: Improper technique or alignment during activities can increase the stress on the tendon. Factors such as weak quadriceps muscles, tight hamstrings, or incorrect footwear can contribute to this.
  • Sudden increase in activity: Starting a new exercise program or increasing the intensity or duration of workouts too quickly can overwhelm the tendon and lead to inflammation.
  • Age: As we age, our tendons can become less resilient and more susceptible to injury.
  • Underlying conditions: Certain medical conditions, such as arthritis or previous knee injuries, can increase the risk of patellar tendinitis.

Symptoms of Patellar Tendinitis

The primary symptom of patellar tendinitis is pain in the front of the knee, typically between the kneecap and tibia. The pain may be worse during or after physical activity, especially when jumping or running. Other symptoms may include:

  • Tenderness to the touch
  • Swelling
  • Stiffness
  • Difficulty extending the knee fully

Diagnosis of Patellar Tendinitis

Dr. Grimsley can usually diagnose patellar tendinitis based on a physical examination and your symptoms. During the examination, he may press on the affected area to check for tenderness and assess the range of motion in the knee. In some cases, imaging tests such as X-rays or MRI may be ordered to rule out other conditions or to evaluate the extent of the injury.

Treatment for Patellar Tendinitis

The treatment for patellar tendinitis typically involves a combination of rest, ice, compression, and elevation (RICE) to reduce pain and inflammation. Other treatment options may include:

  • Physical therapy: A physical therapist can help strengthen the quadriceps and hamstring muscles, improve flexibility, and teach proper movement techniques to reduce stress on the patellar tendon.
  • Medications: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help alleviate pain and reduce inflammation. In severe cases, stronger pain medications or corticosteroids may be prescribed.
  • Bracing or taping: Wearing a knee brace or using tape can provide support to the patellar tendon and help reduce pain.
  • Injections: In some cases, injections of corticosteroids or platelet-rich plasma (PRP) may be used to reduce inflammation and promote healing.

In most cases, patellar tendinitis can be treated successfully with conservative measures. However, if the condition is severe or does not improve with treatment, surgery may be necessary.

Prevention of patellar tendinitis involves gradually increasing the intensity and duration of workouts, warming up properly before physical activity, and stretching the quadriceps and hamstrings.

Strengthening the quadriceps muscles can also help reduce stress on the patellar tendon. By taking these preventive measures, you can reduce your risk of developing this common knee injury.

Knee injuries can cause trauma to your knee joint, as well as to the bones, cartilage and ligaments that form the joint itself. Patellar tendinitis is a common knee injury that our doctors can treat. Athletes who jump are especially susceptible to patellar tendinitis. When the patellar tendon is inflamed it typically causes pain between your kneecap and your tibia.
