Patellar tendonitis (also known as jumper’s knee) is one of the most common causes of pain just below the kneecap, especially in athletes who run, jump, or change direction frequently.
The problem often isn’t that your tendon is “damaged.” It’s that your tissue tolerance (how much load your tendon can handle) is currently lower than the load you’re asking it to tolerate.
This commonly happens when you:
➡️ Increase your training too quickly
➡️ Play more than your body is prepared for
➡️ Return to sport before rebuilding tendon capacity
And while rest can reduce pain in the short term, it doesn’t increase your tendon’s ability to tolerate future loads. That’s where progressive loading comes in.
The goal of rehab is to gradually expose the tendon to increasing loads so it adapts, becomes stronger, and is better able to tolerate the demands of sport and everyday life.
Here’s a simple progression to get started:
✅ Knee extension isometric: 5 × 10-second holds
✅ Lateral sliders: 2 × 10 reps per side
✅ Cliff divers: 2 × 10 reps
✅ Heel-elevated wall sits: 3 × 15-second holds
Remember: the “best” exercise isn’t a magic exercise…it’s the one that appropriately challenges your tendon based on your current stage of rehab.
Have you ever dealt with jumper’s knee? What sport were you playing?
