Patellar Tendinopathy (Jumper's Knee)
Patellar tendinopathy / patellar tendinitis
Understanding patellar tendinopathy
Patellar tendinopathy — often called "jumper's knee" — is an overuse problem in the tendon that connects your kneecap to your shinbone. Repeated load (especially jumping, running, or a sudden jump in training) outpaces the tendon's ability to recover, and it becomes irritated and sensitive. It's common in active people, and the great majority settle with the right kind of loading. The good news is that a tendon adapts and gets stronger when you load it the right way — which is exactly what this program is built around.
The reassuring outlook
Tendons respond well to patience and the right exercise. It can be a slower recovery than a simple strain — tendons remodel over weeks to months — but the direction of travel is good, and surgery is very rarely needed. The single most effective treatment is progressive strengthening of the quadriceps. Sticking with it, and managing how much load you put on the knee, is what makes it last.
What you might be feeling
The classic symptom is pain right at the front of the knee, just below the kneecap, where the tendon attaches. Early on it shows up with jumping or at the start of activity, or just after a hard session; over time it can creep into stairs and rising from a chair. It's usually activity-related, and tight or imbalanced thigh muscles often play a part.
The key: load the tendon, don't rest it
Here's the counterintuitive part: complete rest doesn't fix a tendon — gradual, progressive loading does. Tendons get stronger and less painful when you load them in a controlled way. We start with steady "isometric" holds (like a wall sit) that often ease tendon pain, then build to slow, heavy strengthening — especially the lowering ("eccentric") phase of an exercise. The art is loading enough to build the tendon without flaring it.
Don't push through pain
One rule matters a lot with tendons: don't train through sharp or worsening pain. A mild ache during loading that settles quickly is usually fine; pain that climbs during or lingers the next morning means you did too much — ease back. Working through real pain tends to make a tendon worse, not tougher. Quality, controlled loading beats grinding it out.
The path ahead
Caring for the tendon is mostly about smart loading and managing how much stress you put on the knee while it adapts. Wherever you're headed — back to your sport, or just comfortable daily activity — progressive quad strength plus load management are the foundation, decided with your care team at your pace.
How this program is built
Each session has a simple shape: a low-impact warm-up, quad strengthening that progresses from steady holds to slow, controlled loading, and gentle quad and hamstring stretching. We dial back the jumping, running, and deep hard squats that flare it early, then add them back gradually as the tendon strengthens. Cycling is a great low-impact way to keep fit in the meantime.
When it flares
Tendons can have grumpy stretches. If it flares: drop back to the steady isometric holds and lighter loading for a few days, ease off impact (jumping/running), ice after activity, and a short course of an anti-inflammatory if that's appropriate for you. Then rebuild the load gradually. A flare doesn't undo your progress.
Other treatment options
Progressive loading and load management do the heavy lifting, and they're the foundation no matter what else is considered. It helps to know the other tools: physical therapy, anti-inflammatories for a rough stretch, and supportive measures like a patellar strap. Some people explore injections; surgery is rarely needed and reserved for the unusual stubborn case. Whether and when to consider anything else is decided with your care team. This program supports you wherever you are on that spectrum.
Tracking how you're doing
Your quick daily check-in — how the knee feels, what you've been doing — gives you and your care team a shared view of how things are trending. Together with your exercise routine, it's a simple way to see your progress and keep your care team in the loop. It is not a monitoring or warning system.
