Patellar tendonitis, often known as “jumper’s knee,” is a common injury among athletes, particularly those involved in sports requiring frequent jumping, running, or sudden changes in direction. This condition results from inflammation of the patellar tendon, which connects the kneecap (patella) to the shinbone (tibia). Patellar tendonitis can limit an athlete’s performance and lead to chronic pain if untreated. Fortunately, targeted strengthening exercises can help reduce the risk of recurrence and support long-term recovery.
In this post, we’ll explore key patellar tendonitis strengthening exercises designed to prevent future injury and keep athletes at peak performance.
Understanding Patellar Tendonitis
Patellar tendonitis occurs when repetitive stress causes tiny tears in the tendon, leading to inflammation and discomfort. Athletes who frequently jump, sprint, or strain their knees excessively are especially vulnerable. Symptoms include pain below the kneecap, especially during running, jumping, or squatting.
While rest is essential for initial recovery, targeted strengthening exercises can enhance tendon resilience and prevent further damage.
Why Strengthening is Key to Preventing Recurrence
Strengthening the muscles around the knee is crucial to reducing the load placed on the patellar tendon. By improving the strength and flexibility of the quadriceps, hamstrings, and calves, you can minimise stress on the tendon and reduce the risk of patellar tendonitis recurring.
Incorporating regular, focused exercises not only helps athletes recover faster but also prepares the tendon to handle high-intensity movements without injury.
Top Strengthening Exercises for Patellar Tendonitis
Below are some practical exercises that specifically target the muscles supporting the patellar tendon, helping athletes build resilience and prevent future injuries.
1. Eccentric Squats
How to do it:
- Stand on a sloped surface or use a wedge to raise your heels.
- Slowly lower into a squat position with control, focusing on a slow eccentric (lowering) phase.
- Hold briefly, then return to the standing position.
- Perform three sets of 10-15 reps.
Why it works:
Eccentric squats are excellent for strengthening the quadriceps without putting excessive strain on the patellar tendon. The controlled lowering motion helps to rebuild tendon strength and improve knee stability.
2. Single-Leg Decline Squats
How to do it:
- Stand with one foot on a decline board or a sloped surface.
- Slowly squat down on one leg, keeping the other leg off the ground.
- Focus on maintaining control throughout the movement.
- Perform three sets of 8-12 reps on each leg.
Why it works:
Single-leg decline squats provide a more targeted approach to strengthening the affected leg, helping balance muscle imbalances and reducing strain on the patellar tendon during high-impact activities.
3. Isometric Wall Sits
How to do it:
- Stand with your back against a wall, feet shoulder-width apart.
- Slowly slide down into a squat position until your knees are at a 90-degree angle.
- Hold this position for 30-60 seconds, keeping your core engaged.
- Perform 3-4 sets.
Why it works:
Isometric wall sits build endurance in the quadriceps, provide stability to the knee joint, and help the patellar tendon withstand repetitive stress.
4. Glute Bridges
How to do it:
- Lie on your back with your knees bent and feet flat on the ground.
- Lift your hips towards the ceiling, squeezing your glutes as you reach the top.
- Hold briefly, then lower your hips back to the ground.
- Perform three sets of 12-15 reps.
Why it works:
Strong glutes are essential for proper knee alignment and reducing pressure on the patellar tendon. Glute bridges activate the posterior chain, improving overall knee stability.
5. Hamstring Curls
How to do it:
- Lie on your stomach with your legs straight.
- Bend your knees and curl your feet toward your glutes, keeping control throughout the motion.
- Slowly return to the starting position.
- Perform three sets of 10-12 reps.
Why it works:
Strengthening the hamstrings helps balance the knee joint and reduces strain on the patellar tendon by ensuring the quadriceps aren’t overcompensating during movement. If you play badminton often, hamstring curls are also an excellent exercise to help you maintain knee mobility!
Stretching to Prevent Patellar Tendonitis
In addition to strengthening exercises, regular stretching can help maintain flexibility in the muscles surrounding the knee, further preventing patellar tendonitis recurrence. Focus on stretching the quadriceps, hamstrings, and calves to improve range of motion and reduce stiffness.
Quadriceps Stretch
- Stand on one leg and pull the opposite foot towards your glutes, feeling the stretch along the front of your thigh.
Hamstring Stretch
- Sit on the ground with one leg extended and the other bent, reaching for a deep hamstring stretch towards your toes.
Calf Stretch
- Place your hands against a wall, step one foot back, and press the heel into the ground to stretch the calf.
Conclusion
Preventing the recurrence of patellar tendonitis requires a strategic combination of strength training and flexibility exercises. By focusing on key muscle groups like the quadriceps, hamstrings, glutes, and calves, athletes can reduce strain on the patellar tendon and lower the risk of future injuries. Consistency is key—integrating these exercises into your routine can keep you performing at your best while minimising knee pain and discomfort.
