Jumpers knee, also known as patellar tendinitis, is a condition characterized by pain and inflammation in the patellar tendon, which connects the kneecap (patella) to the shinbone (tibia). It commonly affects athletes involved in activities that require repetitive jumping or quick changes in direction, such as basketball, volleyball, or track and field.

Jumpers knee is usually caused by repetitive stress on the patellar tendon. This can be due to activities that involve excessive jumping, frequent landings, sudden accelerations, or decelerations. Overuse, improper technique, inadequate warm-up, and muscle imbalances can also contribute to the development of patellar tendinitis.

If you suspect you have jumpers knee or are experiencing knee pain, it is advisable to seek medical attention. A healthcare professional can provide an accurate diagnosis, develop an appropriate treatment plan, and offer guidance on preventing future recurrences.


Jumpers knee, also known as patellar tendinitis, can be classified into different types based on the severity and location of the injury. Here are the main types of jumpers knee:

1. Stage I: This is the early stage of jumpers knee, characterized by mild pain or discomfort in the patellar tendon after physical activity. The pain is usually localized at the lower edge of the kneecap.

2. Stage II: In this stage, the pain becomes more noticeable and may occur during physical activity. The pain can affect performance and may persist after activity. There may be some swelling or thickening of the tendon.

3. Stage III: At this stage, the pain becomes more persistent and can limit participation in physical activities. The pain may occur during and after activity, and there may be difficulty with activities that require jumping or forceful knee contractions. The tendon may be significantly thickened, and there may be signs of degeneration or small tears.

4. Stage IV: This is the most severe stage of jumpers knee. The pain is constant and can be debilitating, affecting daily activities. There may be significant thickening and degeneration of the tendon, with the possibility of partial tears or complete tendon rupture.


Jumpers knee, or patellar tendinitis, is characterized by several common symptoms. Here are the key symptoms associated with this condition:

1. Pain: The primary symptom of jumpers knee is pain, typically felt at the front of the knee, just below the kneecap. The pain may be described as a dull ache, sharp pain, or a burning sensation. It is often aggravated by activities that involve jumping, running, or activities that require bending or straightening the knee.

2. Tenderness: There is usually tenderness and sensitivity around the patellar tendon, which connects the kneecap to the shinbone. Pressing on or palpating this area may elicit pain.

3. Swelling: In some cases, swelling or localized swelling around the patellar tendon may be present. This can cause the knee to appear slightly swollen or puffy.

4. Stiffness: Individuals with jumpers knee may experience stiffness in the knee joint, particularly after periods of inactivity or upon waking up in the morning.

5. Weakness: Some people may notice a feeling of weakness or instability in the affected knee. This can make activities that require strength and stability, such as jumping or landing, more challenging.

6. Pain with jumping or bending: The pain associated with jumpers knee is often exacerbated by activities that put stress on the patellar tendon, such as jumping, squatting, or kneeling. The pain may be more noticeable during these movements and subside with rest.


The diagnosis of jumpers knee, or patellar tendinitis, typically involves a combination of a physical examination and a review of your medical history. Here are some common steps involved in diagnosing this condition:

1. Medical history: Your healthcare provider will ask you questions about your symptoms, their onset, and any activities or sports that may have contributed to your knee pain. They may inquire about your training routine, previous injuries, and any relevant medical conditions.

2. Physical examination: Your healthcare provider will perform a thorough physical examination of your knee. This may involve palpating the patellar tendon to assess for tenderness, checking for swelling or inflammation, and evaluating your knee’s range of motion and strength.

3. Imaging tests: In some cases, imaging tests such as X-rays or MRI scans may be ordered. These tests can help rule out other conditions and provide a more detailed view of the patellar tendon, identifying any abnormalities or signs of tendon damage.

4. Functional assessment: Your healthcare provider may assess your movement patterns and biomechanics to identify any contributing factors to your knee pain. This may involve observing your jumping, landing, or squatting techniques.


The treatment for jumpers knee, or patellar tendinitis, typically involves a combination of conservative measures aimed at reducing pain, promoting healing, and preventing further damage to the patellar tendon. Here are some common treatment options:

1. Rest and activity modification: Resting the affected knee is essential to allow the tendon to heal. Avoid activities that exacerbate your symptoms, such as jumping or running. Your healthcare provider may recommend modifying your training routine to reduce stress on the patellar tendon.

2. Ice therapy: Applying ice packs to the affected area can help reduce pain and inflammation. It is generally recommended to apply ice for 15-20 minutes at a time, several times a day.

3. Physical therapy: A physical therapist can guide you through exercises that stretch and strengthen the muscles around the knee, including the quadriceps and hamstrings. These exercises help to improve the stability of the knee joint and relieve stress on the patellar tendon.

4. Medications: Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, may be recommended to help alleviate pain and reduce inflammation. However, it’s important to consult with your healthcare provider before taking any medication.

5. Bracing or taping: Wearing a patellar tendon strap or using kinesiology tape can provide additional support to the patellar tendon and help relieve symptoms during activity.

6. Extracorporeal Shockwave Therapy (ESWT): In some cases, ESWT may be recommended. This non-invasive procedure uses high-energy sound waves to stimulate healing in the affected tendon.

7. Corticosteroid injections: In certain cases, your healthcare provider may suggest a corticosteroid injection to reduce inflammation and pain. However, this is typically used as a short-term solution and may not be suitable for everyone.

8. Surgery: In rare cases where conservative measures fail to provide relief, surgical intervention may be considered. Surgery aims to remove damaged tissue or repair the patellar tendon.
