Jumper's Knee: Understanding, Prevention, and Treatment

The knee is one of the most complex and heavily loaded joints in the body. For athletes who regularly jump, such as basketball players, volleyball players, and track and field athletes, the knee can become a source of pain and frustration due to a condition known as Patellar tendinopathy of patella tendinopathy. This blog delves deeper into what jumper's knee actually is, how it develops, and what you can do to prevent and treat it.

Jumpers knee is swelling of the tendon that connects the kneecap to the shin bone.

Jumper's knee, or patellar tendinopathy, is an overuse injury affecting the tendon below the kneecap (patellar tendon). This tendon connects the kneecap to the shinbone and plays a crucial role in straightening the knee and absorbing impact during jumping and landing. With jumper's knee, small tears develop in this tendon, leading to pain, stiffness, and sometimes swelling.

Although the condition mainly occurs in athletes who repeatedly jump and land, it can also occur in other sports or activities that put a heavy strain on the knees, such as running, weightlifting or dancing.

Causes of Jumper's Knee

Patellar tendinitis, commonly known as jumper's knee, arises from repeated micro-trauma to the patellar tendon, usually caused by:

1. OverloadIntensive training sessions, such as frequent jumping, accelerating, and braking, place significant strain on the patellar tendon. This can lead to overuse and damage.
2. Insufficient recovery timeA lack of rest between training sessions or matches hinders the healing of micro-tears in the tendon.
3. Poor biomechanicsIncorrect posture, foot position, or movement techniques can increase the load on the knees.
4. Incorrect footwearSportschoenen with insufficient cushioning or stability can contribute to the development of an injury.
5. Muscle imbalanceWeak or unbalanced muscles around the knee and hip can lead to incorrect loading of the patellar tendon.

Symptoms of Jumpers Knee

The main symptom of jumper's knee is pain at the front of the knee, just below the kneecap. This pain can range from mild and aching to sharp and debilitating. Other common symptoms include:

• Pain during activities such as jumping, running or climbing stairs.
• Stiffness in the knee, especially after periods of rest.
• Swelling around the kneecap.
• Tenderness when touching the patellar tendon.
• Reduced performance during sporting activities.

In the early stages of jumper's knee, pain is often only present during or immediately after exercise. As the injury worsens, pain can also be felt at rest and even make daily activities difficult.

Diagnosis

A sports physician, physiotherapist, or orthopaedist can diagnose jumper's knee based on a physical examination and a thorough discussion of your symptoms and activities. Sometimes, additional imaging techniques such as an MRI or ultrasound are used to assess the severity of the tendon damage and rule out other possible causes of knee pain.

Treatment of Jumper's Knee

The treatment of jumper's knee focuses on relieving pain, promoting healing, and restoring normal function. Here are the main treatment options:

1. Rest and adaptation of activitiesReduce or avoid activities that worsen the pain. This often means taking a temporary break from jumping and other strenuous exercises.
2. Ice therapyApply ice to the knee multiple times a day to reduce pain and swelling.
3. PhysiotherapyA bespoke exercise programme can help improve strength, flexibility and stability around the knee. Eccentric exercises (where the muscle lengthens as it contracts) are particularly effective for patellar tendon issues.
4. Footwear and bracesGood sports shoes with sufficient cushioning and support can reduce the strain on your knees. A patella brace or tape can provide additional support.
5. MedicationPainkillers or anti-inflammatory drugs can offer temporary relief, but do not treat the underlying cause.
6. Shockwave therapyFor chronic cases, shockwave therapy can help stimulate tendon healing.
7. InjectionsIn severe cases, a doctor may inject corticosteroids or PRP (platelet-rich plasma) to reduce inflammation and pain. However, this is done with caution due to potential side effects.
8. SurgeryIn rare cases, when conservative treatments are not effective, surgery may be required to remove damaged tissue.

Prevention of Jumper's Knee

Preventing jumper's knee is particularly important for athletes who want to maintain their performance. Here are some tips:

1. Strong musclesStrengthen the muscles around the knee, such as the quadriceps, hamstrings and gluteal muscles, to reduce the load on the patellar tendon.
2. StretchingRegular stretching can help improve the flexibility of the muscles and tendons around the knee.
3. Progressive trainingAvoid sudden increases in training intensity or volume. Gradually build up your activities.
4. Good techniqueWork on your movement techniques, such as jumping and landing, to minimise the impact on your knees.
5. Rest and recoveryEnsure adequate rest between training sessions and matches to prevent overexertion.
6. Quality trainersWear shoes that are suitable for your sport and offer sufficient cushioning and support.

Conclusion

Jumpers knee is a common injury among athletes, but with the right approach, it can be effectively treated and prevented. Recognising the early symptoms and making timely adjustments to your training habits are crucial to prevent further damage. By investing in a strong and balanced physical foundation and a good recovery routine, you can not only avoid injuries but also take your performance to the next level. If symptoms persist, contact a specialist to create a personalised treatment plan and move pain-free as quickly as possible.
