Patellar Tendinopathy: Signs You Shouldnt Ignore

Understanding Patellar Tendinopathy

Definition and Causes

Patellar tendinopathy, often referred to as "jumper's knee," is a condition characterized by pain and tenderness at the inferior pole of the patella (kneecap). This pain is typically aggravated by activities that involve repetitive loading of the patellar tendon, such as jumping, running, and other high-impact sports (Physio-Pedia).

The condition is often caused by overuse and repetitive stress on the patellar tendon, leading to microtears and degeneration of the tendon fibers.

Risk Factors

Several risk factors contribute to the development of patellar tendinopathy:

• The most significant risk factor is high training loads, especially in sports that require frequent jumping and rapid changes in direction, increase the risk of developing this condition.
• Intrinsic factors such as gender, weight, and body mass index (BMI) also play a role.

Patellar tendinopathy is primarily seen in relatively young athletes, particularly men aged 15-30 years old, who participate in sports like basketball, volleyball, athletic jump events, tennis, and football. The prevalence of this condition in elite volleyball and basketball players has been found to be over 40 percent (Physio-Pedia).

Symptoms and Diagnosis

Identifying Patellar Tendinopathy

Patellar tendinopathy, often referred to as jumper's knee, is characterized by pain localized to the inferior pole of the patella. This pain is typically aggravated by activities that load the knee extensor muscles, such as jumping or running (NIH).

You may notice the pain increases with activities that require the patellar tendon to store and release energy.

Common symptoms include:

• Pain at the bottom of the kneecap
• Swelling around the patellar tendon
• Stiffness in the knee, especially in the morning
• Pain that worsens with physical activity

Warning Signs

Recognizing the early warning signs of patellar tendinopathy is essential for preventing the condition from progressing to a more chronic or debilitating stage. Early intervention allows for more effective management and faster recovery.

Common warning signs include:

• Pain Below the Kneecap: A dull, aching pain at the bottom of the patella, especially during or after jumping, squatting, or running.
• Activity-Related Discomfort: Pain that worsens with physical activity, particularly those involving knee extension under load (e.g., stairs, lunges, or explosive movements).
• Morning Stiffness: A feeling of tightness or stiffness in the front of the knee upon waking or after periods of inactivity.
• Tenderness Over the Patellar Tendon: Sensitivity or soreness when pressing directly on the tendon just below the kneecap.
• Progressive Pain Pattern: Discomfort that initially occurs only after activity but begins to appear during and eventually at rest if left untreated.
• Reduced Performance: A noticeable decline in strength, power, or athletic performance due to pain or instability in the knee.

If you’re experiencing any of these symptoms, it's important to reduce tendon load, seek clinical evaluation, and begin appropriate treatment early to avoid long-term tendon degeneration.

Diagnostic Techniques

Diagnosing patellar tendinopathy involves a combination of physical examination and imaging techniques. A sports medicine physician can typically diagnose the condition through a thorough physical examination, assessing the location and severity of the pain.

Imaging techniques used to confirm the diagnosis include:

• Ultrasound: Diagnostic ultrasound is highly effective, with an accuracy rate of 83% in identifying patellar tendinopathy. It can reveal thickening and an increased cross-sectional area of the patellar tendon compared to normal tendons.
• MRI: Magnetic Resonance Imaging (MRI) can provide detailed images of the patellar tendon, helping to assess the extent of the damage and rule out other potential causes of knee pain.

Understanding the symptoms and diagnostic techniques for patellar tendinopathy is crucial for effective treatment and management.

Treatment Options

These treatment options should be treated as a general guideline, always consult with a healthcare professional for personalized guidance on tendinopathy treatment and medication that is right for you.

Conservative Treatments

For those dealing with patellar tendinopathy, non-surgical treatments are often the first line of defense. These treatments aim to reduce pain, improve function, and promote healing.

• Medications: Over-the-counter pain relievers such as ibuprofen or naproxen sodium can provide short-term relief from pain associated with patellar tendinitis. Check out our article on best anti-inflammatory for tendonitis for more information.
• Physical Therapy: Physical therapy is a cornerstone of treatment for patellar tendinopathy. Techniques include stretching and strengthening exercises, knee braces, and iontophoresis (small electric shock therapy).
• Shockwave Therapy: This method is safe for patients unresponsive to conventional therapy. It should be used in combination with other methods for better results. Additionally, USGET (Guided-Galvanic Electrolysis Technique) provides better results than shockwave therapy when combined with eccentric exercise therapy (Physio-Pedia).

Surgical Interventions

In cases where non-surgical treatments do not provide relief, surgical interventions may be considered. Surgery for patellar tendinitis is rare and typically only recommended in severe cases (Mayo Clinic, Cleveland Clinic).

• Tendon Debridement: Removal of degenerated, thickened, or scarred portions of the tendon to stimulate healing and reduce pain.
• Tendon Repair or Reconstruction: If the patellar tendon is partially or fully torn, surgical repair or reconstruction may be performed to restore tendon integrity and function.
• Arthroscopic Surgery: A minimally invasive option where damaged tissue is removed through small incisions using a camera-guided instrument. This approach may lead to faster recovery and less postoperative pain compared to open surgery.

Seek RELIEF®

RELIEF® offers a science-backed, targeted approach to addressing symptoms associated with spinal tendinopathy.^{1,2,3,4,5,6,7,8,9}

Focusing on treating impacted connective tissue, also known as fascia, that surround the affected tendon to promote healing and enable further support for nearby musculoskeletal structures. RELIEF® is a minimally invasive alternative to traditional treatments—and requires no steroids, medication, surgery, anesthesia, or post-procedure immobilization.

Rehabilitation and Prevention

Rehabilitation Exercises

Rehabilitation exercises play a crucial role in managing patellar tendinopathy. Eccentric loading has been the most dominant approach for the rehabilitation of patellar tendinopathy.

Always consult with a healthcare professional before starting a new exercise regimen for your tendinopathy.

Here are some effective rehabilitation exercises:

• Eccentric Squats: Perform squats on a decline board to focus on the eccentric phase.
• Single-Leg Decline Squats: Target the affected leg to increase strength and stability.
• Leg Press: Use a leg press machine to perform controlled eccentric movements.
• Step-Ups: Step onto a platform with controlled eccentric lowering.

Preventive Measures

To reduce the risk of developing patellar tendinitis, individuals can take preventive measures such as warming up before exercise, using proper techniques, wearing appropriate footwear, and gradually increasing the intensity of physical activity (Mayo Clinic).

Key preventive measures include:

• Warm-Up: Always warm up before engaging in physical activities to prepare your muscles and tendons.
• Proper Technique: Use correct techniques during exercises and sports to avoid unnecessary strain on the patellar tendon.
• Footwear: Wear appropriate footwear that provides adequate support and cushioning.
• Gradual Increase: Gradually increase the intensity and duration of physical activities to avoid overloading the tendon.

The most significant risk factor for patellar tendinopathy appears to be training load, which is considered an extrinsic risk factor. While certain intrinsic risk factors have been identified, such as gender, weight, and body mass index, training load remains the most significant.
