Jumper's knee ยท Progressive tendon loading

Patellar Tendinopathy Exercises for Athletes

Slow strength is necessary, but it is not the finish line. Athletes must progress through strength, faster spring-like loading, jumping, sprinting, and repeated sport exposure while monitoring the next-day tendon response.

Build strength before progressing to jumping.

Do not begin every exercise at full volume. Start with the isometric plus two slow strength movements. Add low-level jumping only after slow loading is controlled, baseline symptoms are stable, and there is at least forty-eight hours between early high tendon-load sessions.

Frequency
Strength 3 days per week; jumping initially 2 days per week
Equipment
Strong strap or wall, chair, backpack or weights, optional band or gym equipment
First checkpoint
Adjust at 4 to 6 weeks; judge the strength trial near 12 weeks
Primary goal
Jumping, landing, sprinting, deceleration, and full training capacity
  1. Exercise 1

    Spanish squat or wall-sit isometric

    Daily when useful or before training

    Dose5 holds of 30 to 45 seconds with 1 to 2 minutes of rest

    Sit back against a strong strap behind the knees or use a wall sit. Keep the trunk tall and hold at a tolerable knee angle.

    Make it easier

    Use a shorter hold, shallower knee angle, or bilateral wall sit.

    Progress it

    Increase hold time, knee angle, or resistance without worsening the next-morning tendon test.

  2. Exercise 2

    Slow squat or leg press

    3 nonconsecutive days per week

    DoseStart with 3 sets of 12 to 15 repetitions

    Lower for about 3 seconds and rise for about 3 seconds through a tolerable range. Keep the knee tracking over the middle toes.

    Make it easier

    Use a bilateral box squat, shallower range, or lighter load.

    Progress it

    Increase load while moving gradually toward 4 sets of 6 to 8 repetitions.

  3. Exercise 3

    Slow split squat

    2 to 3 days per week

    Dose3 sets of 6 to 12 repetitions per side

    Keep the front foot grounded and lower slowly with the knee tracking over the middle toes. Use support if needed for balance.

    Make it easier

    Use a shorter depth, hand support, or more assistance from the back leg.

    Progress it

    Add range, backpack or dumbbell load, then emphasize the front leg.

  4. Exercise 4

    Resisted knee extension

    2 to 3 days per week

    Dose3 sets of 8 to 15 repetitions

    Use a band, ankle weight, or machine. Straighten and lower the knee slowly without snapping into extension.

    Make it easier

    Use lighter resistance or a shorter tolerable arc.

    Progress it

    Increase resistance and work gradually toward a heavier 6 to 8 repetition range.

  5. Exercise 5

    Landing drill to low pogo jumps

    2 days per week with at least 48 hours between sessions

    DoseBegin with 2 to 3 sets of 10 controlled contacts

    Start with a quiet landing and hold. Progress to small, quick bilateral pogo jumps while maintaining alignment and a spring-like ankle and knee strategy.

    Make it easier

    Practice a landing without a rebound jump.

    Progress it

    Add rebound speed, then height, then single-leg or multidirectional contacts. Change only one variable per session.

  6. Exercise 6

    Sport-specific jump and acceleration exposure

    1 to 2 days per week after low-level jumping is tolerated

    DoseBegin with 3 to 5 sets of 3 to 5 high-quality efforts

    Select a jump, landing, sprint, or deceleration pattern required by the sport. Track the number, intensity, surface, and next-morning response.

    Make it easier

    Reduce speed, height, approach distance, or total efforts.

    Progress it

    Increase either intensity or volume, one variable at a time, then build repeated efforts and reduce the rest between efforts gradually.

Let the next day guide the dose.

A repeatable load test, such as a decline squat, can help track the tendon. Mild pain can be acceptable when movement stays normal and the tendon returns to its usual baseline by the next morning.

Continue

Green light

Pain stays near 3 out of 10 or less, movement remains normal, and the tendon is back to its usual baseline the next morning.

Adjust

Yellow light

Pain rises across sets, landing strategy changes, or the standard load test is meaningfully worse the next morning. Reduce weight, range, jump intensity, or contact count.

Stop

Red light

Stop. Call 911 for chest pain, trouble breathing, fainting, or another medical emergency. Seek same-day urgent assessment for a sudden sharp pain or pop, new knee-extension weakness, rapid swelling, or inability to perform a straight-leg raise.

Change one variable at a time

When symptoms are too reactive, first reduce range, resistance, repetitions, or frequency. When the current dose feels controlled for several sessions, progress only one of those variables.

Build capacity in stages.

  1. Stage 1: control sudden increases in load

    Reduce the most provocative jump, sprint, or competition volume while maintaining tolerable conditioning and skill work.

  2. Stage 2: build slow strength

    Progress from isometrics to slow controlled strength exercises. Over time the exercises should become meaningfully heavy while the tendon returns to its usual baseline by the next day.

  3. Stage 3: restore jumping and other fast loading

    Add landings, pogo jumps, hops, accelerations, and decelerations with planned repetition counts and recovery days.

  4. Stage 4: return to sport and performance

    Progress from individual drills to partial training, full training, competition, and then the workload needed for performance.

Signs you are ready for the next stage

  • The repeatable tendon load test stays near 2 to 3 out of 10 or less.
  • High-intensity loading returns to baseline by the next morning.
  • The knee has full motion without swelling or a limp.
  • Quadriceps strength and hop or jump capacity are approaching the other side and relevant sport benchmarks, often using 90 percent as one part of the decision, with acceptable movement quality. Symmetry alone can be misleading when both sides are deconditioned.
  • Repeated full training sessions are tolerated without limping, avoiding the involved leg, or changing movement.

When to schedule an evaluation

No single validated return-to-sport test exists for patellar tendinopathy. Review loading and technique at four to six weeks. Reassess the diagnosis and program when there is no meaningful improvement after eight to twelve weeks of consistent progressive loading, or when jump volume, strength deficits, or return-to-sport demands require individualized testing.
