Introduction
Patellar tendonitis, commonly known as jumper’s knee, is an overuse injury affecting the tendon that connects the kneecap (patella) to the shinbone (tibia). This condition often results from repetitive stress on the patellar tendon, particularly in activities involving jumping and running. It can cause pain, tenderness, and reduced function in the affected knee, impacting an individual’s ability to participate in sports and daily activities.
Why It Occurs and Who It Affects
Jumper’s knee is common among youth athletes, often as part of the growing process. During growth spurts, bones may grow faster than muscles and tendons, leading to increased tension and stress on the patellar tendon. Many young athletes may experience this pain while growing, but it often resolves once they reach full skeletal development.
However, it’s crucial to address the issue properly to prevent long-term problems and ensure a safe return to sports activities.
Disclaimer
The information presented here is based on personal experience and research. As the creator of this program, I am a coach and a parent of a child who has dealt with patellar tendonitis for over three years. While I have extensively researched this topic and consulted with medical professionals, I do not have a formal background in sports medicine.
It is crucial to understand that every individual’s condition is unique. Therefore, it is strongly recommended that you consult with a qualified healthcare professional or physical therapist before starting any new exercise program. This guide should not be considered a substitute for professional medical advice, diagnosis, or treatment.
The Importance of Strength Training
It’s crucial to understand that pain medications and supportive devices like patellar tendon straps are temporary fixes. The key to long-term relief and prevention lies in dedicated strength training. This program focuses on building the necessary strength to support your knees and reduce stress on the patellar tendon.
Exercise Routine – Phase 1
Wall Sits: 3 sets of 60 seconds
- Squeeze a book, yoga block, or small ball between your knees
- 15-second break between sets

Perform this routine twice daily, gradually working up to the full program:
Isometric Bend Leg Holds: 3 sets of 45 seconds
- Use ankle weights or a backpack with books/rocks for added resistance

Lunge Isometric Hold: 3 minutes per leg
- Bend your front leg to just before the point of pain, then raise it slightly
- Take short breaks as needed until you can hold for the full 3 minutes
- Take short breaks as needed until you can hold for the full 3 minutes

Foam Roller Isometric Hamstring Curl Holds: 3 sets of 60 seconds, with 30 seconds rest between sets
- Bridge up as high as possible
- Pull the foam roller toward your buttocks
- Point toes down into the foam roller
- Lift heels, balancing on the balls of your foot bridge up as high as possible

Tibialis Raises: 2 sets of 20 repetitions
- Stand with your back against a wall, heels about 6 inches from the wall
- Lift your toes towards your shins, keeping your heels on the ground
- Hold for a second, then lower your toes back down
- This exercise strengthens the tibialis anterior muscle, which can help improve knee stability

Calf Stretch: 60 seconds per leg
- Use a slanted surface (board, block, or book)

Couch Quad Stretch: 60 seconds per leg
- Use a pillow under your knee on hard surfaces

Remember to perform these exercises with proper form and to progress gradually. If you experience pain during any exercise, stop and consult with a healthcare professional.
Pain Management and Safety
- Don’t exercise if pain exceeds 3/10
- Monitor pain levels 24 and 72 hours post-exercise if pain is worse then you need to reduce your workout by half and work your way back up
- Progress gradually and prioritize consistency
- Regular, pain-free exercise is more beneficial than pushing too hard and causing a setback
Nutrition and Supplements
Proper nutrition plays a crucial role in tendon health and recovery. While a balanced diet is essential, certain supplements may help support the healing process for patellar tendonitis.
Collagen and Vitamin C
Taking a collagen supplement along with vitamin C may help support tendon healing:
- Recommended: Vital Proteins® Collagen Peptides Chocolate Dietary Supplement Powder, taken with a vitamin C supplement – we like it because the flavor is better than than just plain collagen. Also, this mixes well in a blender with a chocolate protein powder added in.
- Timing: Take 45 minutes prior to exercise on workout days, and at a consistent time on non-exercise days
- Why it may work: Collagen is a major component of tendons. Supplementing with collagen peptides, especially when combined with vitamin C (which aids in collagen synthesis), may support tendon repair and strength. Several studies have shown improved recovery and reduced joint pain in athletes taking collagen supplements.
Anti-inflammatory Supplements
Anti-inflammatory supplements may help manage pain and support the healing process:
- Recommended: Advanced Boswellin Super and PS + Curcumin C3 1000 mg with Bioperine – Amazon
- Why it may work:
- Boswellia (Boswellin) has natural anti-inflammatory properties and may help reduce pain and inflammation in joints.
- Curcumin, the active compound in turmeric, is known for its potent anti-inflammatory and antioxidant effects. It may help reduce pain and improve function in people with joint issues.
- Bioperine (black pepper extract) enhances the absorption of curcumin, making the supplement more effective.
- PS (Phosphatidylserine) may help reduce exercise-induced stress and support muscle recovery.
Important Notes on Supplements
- While these supplements may be beneficial, they are not a substitute for proper nutrition, rest, and the strengthening exercises outlined in this guide.
- The effectiveness of supplements can vary from person to person.
- Always consult with a healthcare professional before starting any new supplement regimen, especially if you have any existing health conditions or are taking medications.
- Purchase supplements from reputable sources to ensure quality and safety.
Remember, nutrition and supplementation should complement your exercise routine and overall treatment plan, not replace them. The primary focus should always be on proper strength training, gradual progression, and listening to your body.
Footwear Considerations
Proper footwear plays a crucial role in knee health and can significantly impact the stress placed on your patellar tendon. Consider the following:
- Recent Changes: Have you recently switched to new shoes? A change in footwear can alter your gait and the distribution of force through your legs, potentially contributing to knee pain.
- Wear and Tear: Are your current shoes worn out? Shoes with inadequate support or excessive wear can cause added stress on your knees.
If you’re experiencing knee pain, evaluating and potentially updating your footwear could be an important step in your recovery process.
Supportive Devices – Patellar Tendon Strap
While not a long-term solution, a patellar tendon strap can provide some relief:
- It applies pressure just below the kneecap, aligning the patellar tendon
- This changes the force direction and magnitude on the knee
- Proper placement is crucial: the strap should sit directly under the kneecap
- Not a long-term solution; address underlying causes with a healthcare professional
- Can be found in sports goods stores or online, often for less than $18 – left is the model my son like best from Amazon

Remember, while supportive devices can help manage pain, they do not replace the necessary strength training exercises.
Looking Ahead: Phase 2
This guide outlines Phase 1 of the program, focusing on developing basic strength and stability. Phase 2, which will be introduced later, will incorporate low-level plyometrics to work on tendon elasticity, improving the tendon’s ability to store and release energy. It’s crucial to build a strong foundation in Phase 1 before progressing to the more dynamic exercises in Phase 2.
Conclusion
Managing patellar tendonitis requires dedication to strength training and a patient, progressive approach. While supportive devices, proper nutrition, and pain management techniques can help, they do not replace the hard work of strengthening the muscles supporting your knees. Remember that for many young athletes, this condition may improve with proper management and full skeletal development. Stick with the program, progress gradually, and consult with healthcare professionals as needed. With consistent effort and proper care, you can overcome jumper’s knee and return to your athletic activities stronger than before.
