Guided rehab · Knee: jumper's knee (patellar tendon)

Jumper's knee exercises at home

Calm a sore tendon below the kneecap with holds, then rebuild it slowly.

Welcome to your jumper's knee program. Tendons like steady, gradual loading, so we start with holds and build up slowly.

Check with your physiotherapist or doctor before starting. Show them this program; in the app you'll confirm they've said it's OK for you before your first session. Exercise education, not medical advice. This is general guidance for common, non-serious knee pain, not a diagnosis or a substitute for a physiotherapist or doctor. Stop if pain is sharp or getting worse, and check the warning signs below before you start. Do the exercises on your sore side unless told otherwise.

The program: 3 phases

Some discomfort below the kneecap is okay if it stays at three out of ten or less and settles by the next morning.

Warning signs: get checked first

Don't start, or stop, and see a health professional if you answer yes to any of these. Red items need urgent care.

  • Are you unable to take four steps on the leg?
  • Is there tender bone at the kneecap or just below the knee on the outside?
  • Does your knee lock, or get stuck so you cannot straighten it?
  • Did your knee swell up a lot within a few hours of an injury?
  • Did you hear a pop, or has the knee given way since an injury?
  • Do you get chest pain, pressure or tightness with activity or at rest?
  • Have you fainted, or had dizziness that made you lose balance, in the last 6 months?
  • Do you have high blood pressure that is not under control?

Do it with Apex One

Check with your physiotherapist or doctor before starting. Apex One+ then turns this program into guided sessions: a quick safety check, your confirmation that they've OK'd the program, a pain rating before and after, every exercise talked through out loud, and holds timed for you. Reps are counted out loud at a steady pace; the camera isn't used in rehab sessions. When your knee is coping, you move up a phase.

Questions

How often should I do jumper's knee exercises?

In this program, phase 1 (settle) is daily; later phases are every other day. Little and often works best, and rest days let the knee adapt.

Should jumper's knee exercises hurt?

Some discomfort below the kneecap is okay if it stays at three out of ten or less and settles by the next morning.

When should I move to the next phase?

Move up when the current phase feels comfortable, pain stays low during and after sessions, and your knee settles by the next day. If pain flares, drop back a phase for a few sessions.

When should I see a physiotherapist or doctor?

Get assessed before starting if any warning sign below applies, if the pain followed a fall or injury, or if it is severe, getting worse, or not improving after a few weeks of regular exercise. Seek urgent care for symptoms like: do you get chest pain, pressure or tightness with activity or at rest.

Can an app guide my rehab exercises?

Yes, once your physiotherapist or doctor has said the program is OK for you. Apex One+ walks you through this program out loud with timed holds and pain checks before and after every session. It's exercise education, not a diagnosis.
