If you’re experiencing pain just below your kneecap, you might be dealing with jumper’s knee, also known as patellar tendinitis. The good news? Most cases can be treated without surgery.

What is Jumper’s Knee?

The patellar tendon connects your kneecap (patella) to your shinbone (tibia) and plays a crucial role in leg extension during activities like running, jumping, and climbing stairs. When overused or overstressed, this tendon can become inflamed and painful, resulting in patellar tendinitis, commonly called jumper’s knee.

Jumper’s Knee vs. Runner’s Knee

It’s important to differentiate jumper’s knee from runner’s knee (patellofemoral pain syndrome). While jumper’s knee causes pain just below the kneecap, runner’s knee results in pain around or underneath it.

Who Gets Jumper’s Knee?

Jumper’s knee typically affects athletes who perform a lot of jumping or sprinting—think basketball, volleyball, or track athletes. However, anyone who increases activity levels suddenly or works extensively on their feet can develop it. Tight muscles, weak hips, and poor movement form are major risk factors.

Symptoms of Jumper’s Knee

  • Pain and tenderness just below the kneecap

  • Stiffness or swelling in the tendon

  • Discomfort during activities like squatting, kneeling, running, or descending stairs

Causes of Jumper’s Knee

Patellar tendonitis stems from overuse and overload. Tendons need strength, flexibility, and recovery time. Sudden activity increases, repetitive jumping, tight quads, weak hips, or poor form can overstress the tendon.

Diagnosing Jumper’s Knee

Diagnosis involves:

  • Listening to your activity history and symptoms

  • Physical examination (testing movement and tenderness)

  • High-resolution diagnostic ultrasound imaging to check tendon structure.
    An MRI is rarely needed when ultrasound is available.

Common Myths About Jumper’s Knee

  • “Just rest it.” While early rest helps, tendons need progressive loading to heal.

  • “Steroid injections are the solution.” Steroids may weaken the tendon long-term.

  • “Surgery is necessary.” Most cases heal successfully without surgery.

Non-Surgical Treatment Options

  1. Identify the Root Cause: Address weak hips, tight muscles, poor form, or training errors.

  2. Rehabilitation Plan:

    • Isometric exercises to ease pain

    • Eccentric exercises to rebuild tendon strength

    • Functional training to restore movement patterns

  3. Nutrition and Supplements:

    • Collagen before exercise, Vitamin C for collagen production, Omega-3s for inflammation control

    • Anti-inflammatory diet focusing on whole foods

  4. Regenerative Injection Treatments:

    • Prolotherapy: Natural solution to trigger tendon repair

    • Platelet-Rich Plasma (PRP): Concentrated growth factors from your blood injected into the tendon

    • Bone Marrow Stem Cells: For severe or chronic cases

Treatments to Avoid:

  • Cortisone injections: Short-term relief but long-term tendon damage

  • Prolonged rest without rehab: Leads to weakness and incomplete healing

  • Early surgery: Should only be considered if all conservative options fail

Expected Recovery Timeline

With the right non-surgical plan:

  • Pain improves in a few weeks

  • Strength and function recover in 2–3 months

  • Full recovery without surgery is achievable

Conclusion

Patellar tendinitis, or jumper’s knee, is a treatable condition with a proper diagnosis and a comprehensive non-surgical approach. By addressing the root cause, not just masking the pain, you can get back to living pain-free.
