Patellar Tendonitis: Symptoms, Causes, Tests, and Treatments

Patellar tendonitis, often called "Jumper's knee," is a sports-related injury characterized by inflammation of the patellar tendon, which connects the kneecap (patella) to the shinbone (tibia). This condition is prevalent among athletes playing sports like basketball, volleyball, athletic jump events, tennis, and football, as these activities require repetitive patellar tendon loading. Patellar tendonitis typically affects males aged 18 years and above more than females due to their higher levels of physical activity. In this article, we'll discuss everything you need to know about patellar tendonitis.

Symptoms

The primary symptom of patellar tendonitis is progressive pain at the front of the knee, between the kneecap and the tendon's attachment to the tibia. Initially, the pain interferes with sports activities, but over time, it may become severe enough to disrupt daily activities. The pain is often more pronounced when climbing stairs, standing up after sitting for an extended period, or during activities that involve extending or bending the knees.

Other common symptoms associated with patellar tendonitis include swelling at the front of the knee, tenderness, knee stiffness, and knee joint weakness. Since the pain of patellar tendonitis might be confused with other foot pathologies, it is essential to consult your healthcare provider for a proper examination.

Causes

Patellar tendonitis is primarily caused by overuse of the knee joint, resulting in repetitive force or stress on the patellar tendon, causing tiny tears. The condition is linked to leg muscle contraction and the force of hitting the ground. As the level of physical activity increases, the tear enlarges, leading to inflammation and weakness of the tendon.

Patellar misalignment is another significant cause of patellar tendonitis. It occurs when the patella is not properly aligned, restricting knee movement and causing excessive stress on the patellar tendon, leading to inflammation and weakness over time.

Physical activity, tight leg muscles, leg muscle imbalance, and chronic illnesses disrupting blood flow to the legs are factors that can predispose one to patellar tendonitis. If your knee hurts, do not ignore the pain; rest and ice the affected area.

Patellar Tendonitis Test

If you experience knee pain or any of the previously mentioned symptoms, consult your healthcare provider (doctor and/or physical therapist) for a proper assessment, diagnosis, and treatment of patellar tendonitis. The process typically starts with taking a medical history, followed by a physical examination and, in some cases, imaging tests to obtain a clearer view of the knee joint.

After asking you questions about your medical history, a physician will carry out a physical examination or test by pressing the knee along the patella tendon to check for pain. They will also gently move the knee and its cap in different directions to check for any limitation in the range of motion. Often, patellar tendonitis pain hurts more on the front part of your knee, and the range of motion of the knee joint is painful and limited.

Sometimes, imaging tests including X-ray (to rule out other bone conditions that might cause knee pain), ultrasound (using sound waves to show the tears in your patellar tendon), and Magnetic Resonance Imaging (using a magnetic field to reveal even the slightest changes in your patellar tendon) may be required.

Treatment Options

Your doctor will consider your age, type, and size of the tear, and activity level when planning your treatment. The following options are the first lines of management:

• Immobilization (Rest): Avoid activities and movements that trigger your symptoms, do not push through the pain, stay off your feet, and give your body time to heal. By allowing the affected knee to rest, you can prevent further aggravation of the symptoms and promote faster recovery.
• Apply Ice: Applying ice to the knee relieves pain and reduces swelling. Get an ice pack and place it on the front part of the knee for 15 minutes twice daily, preferably in the morning and at night. Alternatively, you can break the ice into smaller fragments, wrap it in a medium-sized towel, and wrap it around your knee, ensuring the ice is positioned on the anterior surface of the knee.
• Physical Therapy: Strengthening and stretching exercises increases the flexibility of the injured tendon tissues and relieves pain. Physical therapists can create a personalized program that targets specific muscle groups and tendons to ensure optimal recovery and prevent future injuries.
• Supportive devices: Knee brace and supportive foot orthotics can address foot posture problems and reduce excessive motion across the knee joint. These devices provide additional support and stability to the knee, allowing it to heal more effectively while minimizing discomfort during daily activities. They need to be fitted perfectly as they might slow down the healing process or provide inadequate support if they're too tight or too loose, respectively.

Road to Recovery

Patellar tendonitis can be frustrating and painful, particularly for athletes and physically active individuals. However, with prompt and proper treatment, most people recover and resume their normal activities. Remember not to push through the pain and always seek medical attention if you experience persistent pain or symptoms, as untreated patellar tendonitis can lead to more severe complications.
