Patellar Tendonitis: What You Need to Know

If you're experiencing pain below your kneecap, especially during activities like jumping or running, you may have patellar tendonitis. This common overuse injury, also called jumper's knee, occurs when the tendon connecting your kneecap to shinbone becomes inflamed. You'll typically feel pain, swelling, and stiffness that worsen with activity. Treatment usually starts with rest, ice, and anti-inflammatory medication, while physical therapy helps strengthen surrounding muscles. Prevention involves proper warm-ups, gradual training increases, and good footwear. While most cases improve with conservative treatment, understanding your risk factors and early warning signs leads to better outcomes.

Understanding Jumper's Knee

When athletes experience persistent knee pain during jumping activities, they're often dealing with patellar tendonitis, commonly known as jumper's knee. This condition affects the patellar tendon, which connects your kneecap to your shinbone, and it's particularly common in sports that involve frequent jumping and explosive movements. Knee joint inflammation is a common underlying factor in many knee-related sports injuries. Running-related knee stress can also contribute to the development of this condition, making it important for athletes to understand proper training techniques.

You're most likely to develop jumper's knee if you participate in activities like basketball, volleyball, or track and field. The condition typically develops due to repetitive strain and overuse, especially when you're pushing your body beyond its normal limits. Several factors can increase your risk, including:

• Tight quadriceps and hamstrings
• Excessive body weight or high BMI
• Training on hard surfaces
• Poor biomechanics
• Previous knee inflammation

What's happening inside your knee is a series of micro-tears in the tendon tissue. While it's often called tendinitis, it's more accurately described as tendinosis since there's usually no inflammation present. The pain typically concentrates at the bottom tip of your kneecap, and you'll notice it most when jumping, landing, or climbing stairs. Ibuprofen or naproxen sodium can provide temporary relief from the discomfort.

Common Signs and Symptoms

The first sign that you're developing patellar tendonitis is typically pain below your kneecap. This pain can range from mild to severe and usually centers on the lower part of your patella. You'll likely notice that the discomfort persists as a dull ache, even after you've finished your activities. Physical therapy exercises can help strengthen the surrounding muscles and provide support to the affected area. Knee joint inflammation can also contribute to the development of this condition.

Athletes who participate in high-impact sports activities are particularly susceptible to developing this condition.

You may experience these key symptoms:

• Swelling beneath your kneecap
• Weakness when trying to straighten your knee
• Stiffness, especially in the morning
• Tenderness when touching the front of your knee

Your symptoms will often worsen during specific activities. You'll notice increased pain when:

• Jumping or landing from jumps
• Running, particularly on hard surfaces
• Climbing up or down stairs
• Performing squats, especially on a decline
• Sitting for long periods

The pain you feel is typically dose-dependent, meaning it gets worse the more stress you put on your patellar tendon. If you're an athlete, you might notice that your performance in activities requiring explosive movements, like jumping or sprinting, becomes compromised. The tendon may also feel thickened compared to your other knee.

What Causes Patellar Tendonitis

Patellar tendonitis typically develops from repetitive stress and overuse of your knee joint, particularly during activities that involve jumping and running. Your risk increases if you're involved in sports like basketball, volleyball, or football, where frequent jumping puts intense strain on your patellar tendon. Studies show that forces up to fivefold your body weight impact your knees during running activities.

Several factors can make you more susceptible to this condition:

Physical Characteristics:

• Being overweight or having a high body mass index
• Differences in leg length
• Being male, especially if you're between 15-30 years old
• Having misaligned feet, ankles, or legs

Training and Equipment Issues:

• Exercising on hard surfaces
• Wearing shoes with inadequate padding
• Suddenly increasing your workout intensity
• Making abrupt changes to your running shoes

Muscle-Related Factors:

• Tight quadriceps and hamstrings
• Muscle imbalances that cause uneven pulling on your tendon
• Poor flexibility in your leg muscles

Environmental and health factors can also contribute to patellar tendonitis. If you have chronic diseases that affect tendon strength or train with excessive loads, you're at higher risk of developing this condition.

Diagnosis and Medical Assessment

Diagnosing patellar tendonitis requires an extensive medical assessment that typically begins with a physical examination and detailed review of your symptoms. Your doctor will want to know when you experience pain, particularly during activities like jumping or running, and how it affects your daily activities. They'll also examine your entire lower body to check for related issues in your hips, knees, and ankles.

The Royal London Hospital Test is commonly used to assist in diagnosis. Several imaging tests may be used to confirm the diagnosis:

• X-rays: To check your knee's bone structure
• Ultrasound: Provides detailed images of your patellar tendon
• MRI: Shows thorough views of soft tissues and can detect tendon damage

Your doctor will likely perform specific tests, including checking for pain when your knee is flexed at 120 degrees or during resistance exercises. It's important to note that while imaging tests are helpful, they don't always tell the complete story – you might have abnormal findings on an MRI but experience no symptoms, or vice versa.

The most accurate diagnostic approach combines ultrasound (both grayscale and color Doppler) with clinical examination, as this combination has proven more reliable than MRI alone in confirming patellar tendinopathy.

Treatment Options and Recovery

Once you've received a clear diagnosis, your doctor will develop a thorough treatment plan tailored to your specific condition and lifestyle needs. Your treatment will likely begin with conservative approaches, including medications like ibuprofen or naproxen to manage pain and inflammation.

Physical therapy plays a vital role in your recovery. You'll learn specific exercises to strengthen your thigh muscles and gentle stretching techniques that help reduce muscle spasm. Poor muscle flexibility often contributes to this condition, especially in the quadriceps and hamstrings. It's important that you avoid bouncing during stretches to prevent further injury.

Supporting devices can provide additional relief during your recovery:

• Patellar tendon straps
• Knee braces
• Compression sleeves
• Ice therapy after activity
• Heat application before exercise

For more severe cases that don't respond to conservative treatment, your doctor might recommend advanced interventions. These could include corticosteroid injections, platelet-rich plasma therapy, or iontophoresis. While surgery is typically reserved as a last resort, it may be necessary if you have significant tendon damage or if other treatments haven't provided relief. Throughout your recovery, your healthcare team will monitor your progress and adjust your treatment plan as needed.

Prevention and Long-Term Management

To effectively prevent patellar tendonitis and manage it long-term, you'll need to adopt several key strategies that work together. Start by gradually increasing your exercise intensity and ensuring you're using proper form during activities. Don't forget to wear appropriate footwear that provides adequate support for your specific needs. Tiny tears and inflammation can develop when proper prevention isn't followed.

Strengthening your leg muscles is essential for prevention. Focus on exercises that target your:

• Quadriceps (try straight leg raises)
• Hamstrings (include bridges and curls)
• Hip muscles (incorporate side-lying leg lifts)

Make these lifestyle adjustments part of your routine:

• Always warm up and cool down properly
• Cross-train to avoid overuse
• Replace your athletic shoes regularly
• Listen to your body and address pain early

For long-term management, you'll want to maintain a consistent stretching routine and consider using knee support when needed. If you're an athlete, work with your coach to modify training intensity and incorporate rest periods. Regular check-ups with your healthcare provider can help monitor your progress and prevent recurrence of symptoms.
