Patellar Tendinitis

Overview

Patellar tendinitis is a problem with the tendon that connects your kneecap to your shinbone. This tendon, along with the muscles in the front of your thigh, helps you straighten your knee, allowing you to move, kick, run, and jump. It's like a strong rope connecting your kneecap to your lower leg, essential for these movements.

This condition is sometimes called "jumper's knee" because it's more common in athletes who jump a lot, like basketball and volleyball players. But anyone can get it, even if they don't play sports that involve lots of jumping.

Usually, the first treatment for patellar tendinitis involves physical therapy. This helps by stretching and strengthening the muscles around your knee. A physical therapist can teach you specific exercises to improve the strength and flexibility of the muscles that support your knee, making the tendon less stressed.

Symptoms

Patellar tendinitis, often called jumper's knee, is a common knee problem. The main symptom is pain, usually felt around the kneecap where the tendon connecting the kneecap to the shinbone (tibia) is.

At first, the pain might only happen when you start exercising or right after a tough workout. This pain gradually gets worse. It might start affecting your ability to do sports activities. Eventually, the pain becomes bad enough to bother everyday activities like going up stairs or getting up from a chair.

When to see a doctor

Knee pain is common, and often you can manage it at home. A good first step is to apply ice to the painful area. Also, try to avoid or limit activities that make your knee hurt. This gives your knee a chance to rest and recover.

However, if your knee pain:

  • Doesn't go away or gets worse: This could be a sign of a more serious problem.
  • Makes it hard to do everyday things like walking, climbing stairs, or getting dressed: If your pain is significantly impacting your daily life, it's time to seek help.
  • Comes with swelling or redness around the knee joint: These signs could indicate inflammation or infection, which need medical attention.

In these situations, it's important to contact your doctor to get the proper diagnosis and treatment.

Causes

Knee pain, often called patellar tendinitis, happens when the tendon connecting your kneecap (patella) to your shinbone gets stressed too much. This happens from doing the same activities repeatedly, like running or jumping.

These repeated movements cause tiny tears in the tendon. Your body tries to fix these tears, but as more tears appear, the tendon becomes inflamed and weaker. This inflammation and weakness can lead to pain. If this tendon damage lasts for more than a few weeks, it's called patellar tendinopathy.

Risk factors

Patellar tendinitis, often called "jumper's knee," can result from a mix of things. Here are some common causes:

  • Exercise: Activities like running and jumping put a lot of stress on the tendon beneath your kneecap (patellar tendon). Suddenly increasing the intensity or frequency of these activities, or even changing your running shoes, can also strain the tendon. This is because the tendon needs time to adapt to the new demands.
  • Tight Muscles: Tight muscles in your thighs (quadriceps) and the back of your thighs (hamstrings) can make your patellar tendon work harder. This extra strain can lead to inflammation and pain.
  • Muscle Strength Differences: If some muscles in your legs are stronger than others, this imbalance can put extra stress on the patellar tendon. Imagine one side of a rope being pulled much harder than the other; this uneven pull can cause damage.
  • Health Conditions: Certain health problems can affect blood flow to your knee, making the tendon weaker and more susceptible to injury. These include kidney problems, autoimmune diseases (like lupus or rheumatoid arthritis), and metabolic diseases (like diabetes). These conditions can disrupt the body's natural healing processes, making it harder for the tendon to recover from stress.
Complications

If you ignore knee pain, pushing through the discomfort instead of listening to your body, you risk making the problem worse. Small tears in the patellar tendon can get bigger. This can lead to ongoing knee pain and problems using your knee properly. If you don't address the pain, it could develop into a more serious condition called patellar tendinopathy.

Prevention

Preventing Patellar Tendonitis (Jumpers' Knee)

Patellar tendinitis, sometimes called "jumper's knee," is a painful condition affecting the tendon connecting your kneecap to your shinbone. You can lower your chances of getting it by following these simple steps:

  1. Listen to Your Body: If you feel pain in your knee during or after exercise, don't ignore it. Immediately apply ice to the affected area and take a break from activities that put pressure on your knee. This is crucial. Don't push through the pain; it will only make things worse. Continue resting until the pain is gone. This might mean taking a few days or even weeks off from activities that aggravate the pain.

  2. Strengthen Your Thighs: Strong muscles in your thighs (quadriceps) can better support your knee and prevent the tendon from being overworked. One particularly effective type of exercise is eccentric training. Eccentric exercises involve slowly lowering a weight or your body part (like your leg) after extending it. For example, slowly lowering your leg after straightening your knee. These exercises help build strength in the muscles that control the movement and reduce the stress on the tendon. Think of it like strengthening the support beams of a building.

  3. Master Proper Technique: Learning the right way to use equipment or perform movements is important. If you're new to a sport or exercise routine, consider taking lessons from a qualified instructor or coach. Proper form reduces strain on your body, including your patellar tendon. A professional can teach you the correct technique to avoid injury. If you're using weights or equipment, make sure you're using the proper form to avoid putting extra stress on your tendon.

Diagnosis

When you see a doctor about knee pain, they might press on different parts of your knee to find out exactly where it hurts. Knee pain from patellar tendinitis, often called "jumper's knee," usually happens on the front of the knee, right below the kneecap.

To figure out what's going on, your doctor might order one or more tests:

  • X-rays: X-rays are useful for making sure there aren't any problems with the bones in your knee that could be causing the pain. For example, they can show if you have a fracture or other bone issue.

  • Ultrasound: This test uses sound waves to create a picture of your knee tissues. It can help show if there's a tear or other damage in the patellar tendon. Think of it like a visual check-up of the tendon.

  • MRI (Magnetic Resonance Imaging): An MRI uses a powerful magnet and radio waves to create detailed images of your knee. This is very helpful in showing small tears or other subtle problems in the patellar tendon that might not be visible with other tests. It gives doctors a very clear picture of the soft tissues within your knee.

Treatment

Patellar Tendinitis Treatment: A Step-by-Step Approach

Patellar tendinitis, often called "jumper's knee," causes pain around the kneecap. Doctors typically start with simple treatments before moving to more involved options.

Initial Treatments:

Over-the-counter pain relievers like ibuprofen (Advil, Motrin) or naproxen (Aleve) can offer temporary pain relief. These medications help reduce inflammation and ease discomfort.

Physical Therapy:

Many physical therapy techniques can help manage patellar tendinitis symptoms. These often include:

  • Stretching: Gentle, consistent stretching exercises are key. Hold each stretch for a few seconds without bouncing. This helps loosen tight muscles and improve flexibility in the area surrounding the tendon.
  • Strengthening: Strong thigh muscles are important for supporting the patellar tendon. Exercises that involve slowly lowering the leg after extending it, or exercises that strengthen all the leg muscles together (like leg presses), can be very helpful.
  • Support Straps: A strap placed around the patellar tendon can help distribute the force away from the tendon, reducing pain.

Advanced Treatments (If Conservative Options Don't Work):

If initial treatments don't provide enough relief, your doctor might recommend more advanced therapies:

  • Iontophoresis: A small electrical current is used to deliver a corticosteroid medicine directly to the affected area through the skin. This can help reduce inflammation.
  • Corticosteroid Injections: A corticosteroid injection, guided by ultrasound, can help reduce pain by targeting the inflamed area around the tendon. However, these injections can weaken the tendon, increasing the risk of tears or ruptures. Therefore, they are typically a last resort.
  • Platelet-Rich Plasma (PRP) Injections: These injections use the patient's own blood to stimulate healing. Studies are ongoing, but PRP injections are sometimes used for chronic patellar tendinitis to encourage new tissue growth and repair damaged tendon.
  • Oscillating Needle Procedure: Using local anesthesia and ultrasound guidance, a small needle makes controlled cuts to remove damaged tendon tissue. This procedure is still relatively new but shows promise for treating patellar tendinitis.
  • Surgery: In very rare cases where other treatments haven't worked, surgery to repair or remove damaged tissue might be necessary. Modern surgical techniques often involve small incisions around the knee.

Important Note: It's crucial to discuss all treatment options with your doctor to determine the best course of action for your specific situation. Your doctor will consider the severity of your condition, your overall health, and your lifestyle to recommend the most appropriate approach.

Self-care

Knee pain? Here's how to ease it:

If your knee hurts, there are some simple things you can try.

  • Pain medication: Over-the-counter pain relievers like ibuprofen or naproxen can help reduce pain for a while. These medicines can help lessen the discomfort, but they don't fix the underlying problem. Follow the directions on the package carefully.

  • Rest and modify activities: If certain activities make your knee hurt, you might need to cut back or change what you're doing. This could mean playing your sport less frequently or trying a less demanding activity for a time. Pushing through the pain could make the problem worse, especially if it involves your patellar tendon. For instance, if running hurts your knee, try swimming or cycling instead. Give your knee time to recover.

  • Ice application: Applying ice can help reduce swelling and pain. Put ice in a plastic bag, wrap it in a towel, and place it on the affected area. Another way is to freeze water in a plastic cup, wrap it in a thin cloth, and gently massage the ice over your skin. This helps to numb the area and reduce inflammation. Apply ice for 15-20 minutes at a time, several times a day, especially after activities that cause pain. Don't apply ice directly to your skin for too long, as this could cause skin damage.

Preparing for your appointment

If your knee hurts after exercise, and ice and rest don't help, see a doctor. They might send you to a sports medicine doctor for more specialized care.

Getting Ready for Your Appointment:

Here are some things to think about and questions to ask your doctor if you think you might have patellar tendinitis (pain in the tendon below your kneecap). Don't hesitate to ask anything else that comes to mind.

Your doctor will probably ask you questions like these:

  • Describe your pain: Tell your doctor exactly how your knee hurts, and when it started.

  • Your health history: Write down any other health problems you have, any medicines or supplements you take, and any allergies.

  • Your exercise routine: Describe your usual exercise, how long and how hard you exercise, and what kind of activities you do. If you've recently changed anything about your exercise routine, like the intensity, the type of exercise, or your equipment (like running shoes), be sure to mention that.

  • Recent injuries: Has your knee been hurt recently? If so, describe the injury.

  • Your questions: Write down any questions you have so you can ask your doctor everything you need to know. Some examples include:

    • What's the most likely cause of my knee pain?
    • Do I need any tests (like X-rays or scans)?
    • What's the best treatment plan?
    • Can I keep playing sports while I recover, and if so, when can I expect to be back to normal?
    • What exercises can I safely do while my knee heals?
    • What at-home care can I do to help?
    • Should I see a specialist?

Your doctor might also ask questions like these to understand your pain better:

  • How bad is the pain? Is it getting worse?
  • When does the pain happen? Before, during, after, or all the time?
  • Is there any swelling or other problems with your knee? Does your knee feel like it's locking or giving way?
  • How does the pain affect your daily activities? Can you walk, climb stairs, or exercise normally?
  • Have you tried any home treatments? What worked, and what didn't?

By being prepared with these questions and details, you can have a more productive and helpful appointment with your doctor.
