Patellar Tendonitis/Jumper’s Knee Exercises

Jumpers knee exercises

Jumper’s knee or Patellar tendonitis exercises are an important part of our full step-by-step rehabilitation program.

Our full, step-by-step Jumper’s knee rehab program has been created by elite level sports physio Paul Tanner and comprises four phases. At each phase exercises become progressively more advanced:

  • Phase 1: Acute
  • Phase 2: Isotonic exercises
  • Phase 3: Heavy slow resistance
  • Phase 4: Eccentric loading

Phase 1 Jumpers knee exercises

Phase 1 begins as soon as possible after injury. During this phase you aim to reduce pain and swelling. However, there are a number of exercises you can still do during phase 1.

The following Jumper’s knee exercises form part of our full rehab program and are done alongside treatment methods including rest, cold therapy, taping/bracing and foam roller.

Only move onto phase 2 when you have achieved the Exit Criteria for this phase.

Stretching & mobility

Stretching the quadriceps muscles at the front of the thigh are particularly important and should be done regularly if pain allows.

Quadriceps stretch

Quadriceps stretch - jumper's knee exercises

This stretch is especially important for Patella tendonitis.

Keep your knees together and gently pull your leg up. You should feel a stretch at the front of the leg which should not be painful.

Hold onto something for balance if you need to or try holding your ear with the opposite arm.

Hold the stretch for 30 seconds and repeat with a short break in between. Aim to do this exercise 1-2 times per day.

This should be comfortable, don’t force the stretch.

Hamstring stretch

Standing static hamstring stretch

Hamstring muscles can be stretched in a variety of ways. Stand on one leg with the other resting on a bench or similar. Ease into the stretch and hold.

Active ankle mobility

Ankle mobility exercise

This involves simply bending and straightening your ankle as far as is comfortable. The aim is to maintain joint mobility.

Hip flexor stretch

This exercise stretches the iliopsoas muscle and rectus femoris. Place one knee on the floor and the other foot out in front with the knee bent. Be careful to use on a mat or padding under the painful knee so as not to aggravate your injury.

Push your hips forward and keep your back upright. You should feel a stretch at the front of the hip and upper thigh.

Hold for 10-30 seconds. Repeat 3 times and stretch at least 3 times a day.

Activation exercises

Activation exercises can be done daily, or at least 3 times per week. They are important for making sure your hip and gluteal muscles do not ‘switch off’ whilst you are unable to train normally.

Clam in extension

Raise and lower your knee, making sure your hips do not rotate backwards whilst performing this exercise.

Double leg bridge

Double leg bridge

Raise your hips up and hold of a couple of seconds before lowering.

Do 3 sets of 12 reps with a short break between sets.


These exercises aim to strengthening specific muscle groups. It is too early to begin overloading your injured knee. Therefore, the priority in phase 1 is calf muscle strengthening.

Single leg calf holds

Single leg calf holds

Stand on the edge of a step and allow all your weight onto one leg. This exercise is isometric, meaning it does not involve any movement.

Start with 5 sets of 15 second holds, building to 5 sets of 45 second holds.

Movement control

These are not specific Jumper’s knee exercises, however, they are important for maintaining and improving proprioception and coordination. They can be done daily.

Gym ball bridge

Gym ball bridge jumper's knee exercises

Perform 3 sets of 8 reps with your legs up on a gym ball (if available). If not, then a chair is ok instead.

Single leg stand

Single leg balance

Stand on one leg for 20 seconds and repeat 4 times.

If you find this too easy then close your eyes. Or use a wobble board or cushion to make it even more difficult.

Phase 1 Exit Criteria

Move on to phase 2 when:

  • Normal daily activities including walking and stairs (down) are pain-free.
  • You can do 10 double leg squats pain-free.
