Patellar tendinitis, commonly referred to as “jumper’s knee,” is a painful and often debilitating condition that affects the knee joint. This injury is especially common among athletes and active individuals who are engaged in high-impact activities. The condition targets the patellar tendon, a thick, fibrous band that connects the kneecap (patella) to the shinbone (tibia). 

This tendon is essential for leg movement, particularly in activities that involve bending, jumping, and running. Repetitive motion and high forces placed on the knee can strain the tendon, causing tiny tears in its fibers. Over time, these micro-tears lead to inflammation, resulting in ongoing pain and sensitivity in the front of the knee.

Causes

Patellar tendinitis typically develops from overuse, especially in sports that demand strenuous jumping, running, or sudden stops and starts, like basketball, volleyball, and soccer. When athletes repeatedly place stress on the knee, it strains the patellar tendon. 

Common Symptoms

Patellar tendinitis presents with several signs and symptoms that can range from mild to severe. 

• Pain Just Below the Kneecap – The primary symptom is localized pain at the bottom of the kneecap, where the patellar tendon attaches to the bone. This pain may initially be mild and only occur after physical activity but can worsen over time.
• Knee Stiffness – Many people with patellar tendinitis experience stiffness in the knee, especially after long periods of sitting or inactivity. Bending the knee may feel uncomfortable or restricted.
• Swelling and Tenderness – Swelling can occur around the patellar tendon due to inflammation, and the area may feel tender to the touch. You might notice this swelling even without much physical activity, as the tendon remains irritated.
• Pain That Increases with Physical Activity – Pain often intensifies during or after physical activities, particularly those involving jumping, squatting, or running. The tendon may become increasingly sore with each activity, making it challenging to continue or finish.

What Happens if Patellar Tendinitis Goes Untreated?

Ignoring patellar tendinitis can lead to serious problems. Over time, the tendon may weaken or become damaged. This can cause pain that doesn’t go away, even during simple activities like walking or climbing stairs.

Without treatment, the tendon can degenerate, leading to stiffness and reduced strength. This makes it harder to move your knee. The weakened tendon may also tear, which often requires surgery to fix.

Untreated patellar tendinitis can also impact your quality of life. Ongoing pain and limited movement can cause frustration or sadness. Early treatment is key to preventing these issues.

Treatment and Recovery

Treating patellar tendinitis, or Jumper’s Knee, focuses on reducing pain, controlling inflammation, and building up strength and flexibility in the knee. A key first step is rest. Taking it easy for a while gives the tendon a chance to heal without added strain. Instead of full rest, modifying activities—like switching to low-impact exercises—can help prevent muscle weakening.

To manage pain and reduce inflammation, ice therapy is often recommended in the early stages. Applying ice to the knee for 15-20 minutes several times a day can help calm the area. Later on, gentle heat can be used to increase blood flow, which supports healing and flexibility. Physical therapy is also incredibly helpful. Strengthening exercises that target the muscles around the knee, such as the quadriceps and hamstrings, improve overall knee support. A specific focus on “eccentric exercises” is especially effective; these involve the controlled lowering phase of movements like squats, which helps build tendon strength.

Anti-inflammatory medications, like ibuprofen or naproxen, can offer short-term relief from pain and swelling. However, they should only be used briefly to avoid side effects. In some cases, knee braces or patellar straps can offer extra support, making it easier to stay active with less strain on the tendon.

For chronic cases that don’t improve with standard treatments, therapies like ultrasound or shockwave therapy might be suggested. These non-invasive methods use sound waves to stimulate blood flow and encourage healing in the tendon.

Surgery is rarely needed and is typically only considered when other treatments have failed. In these cases, a doctor might suggest a procedure to remove damaged tissue or promote new growth in the tendon. 

Recovery from patellar tendinitis varies but often takes several weeks to months, depending on severity. Patience is key. A gradual return to activity is essential to avoid re-injury. It’s important to follow your healthcare provider’s instructions to help you safely regain strength and mobility.

Preventing Patellar Tendinitis

To prevent patellar tendinitis, focus on strengthening and stretching exercises that support your knees. Warming up before activity is also essential, as it prepares the muscles and tendons for stress. Proper footwear, especially during high-impact sports, can further protect your knees and prevent strain.
