Looking for a shorter starting point? The Knee Pain starter guide covers the first 8 exercises on a printable sheet.

A phase-by-phase exercise program used in recovery for knee pain. Each movement includes what it's working on and how it's typically performed. Your own surgeon's or therapist's guidance always comes first.

Phase 1

Quad Sets

Re-activates the thigh muscle and supports knee control.

What it helps: Wakes up the quadriceps — the big thigh muscles that support and control your knee. Getting them firing is the foundation of a strong, steady leg.

  1. Sit or lie with your leg straight.
  2. Tighten the muscle on top of your thigh, pressing the back of your knee down.
  3. Hold briefly, then relax.

Commonly done as 2-3 sets of 10, a few times a day.

Straight Leg Raises

Strengthens the thigh while protecting the joint.

What it helps: Builds quad and hip strength while the knee stays straight, so the muscle works hard without stressing the joint.

  1. Lie down with one leg bent and the other straight.
  2. Tighten your thigh and lift the straight leg a few inches.
  3. Lower slowly.

Tips:

  • Keep the knee straight as you lift.

Commonly done as 2-3 sets of 10, once or twice a day.

Heel Slides

Encourages early, gentle knee motion.

What it helps: Coaxes gentle bending back into the knee — restoring the motion you need for stairs, sitting, and getting in and out of a car.

  1. Lie on your back with your legs straight.
  2. Slowly slide your heel toward you, bending the knee.
  3. Slide it back down.

Tips:

  • Only go as far as is comfortable.

Glute Squeezes

Gently re-engages the buttock muscles.

What it helps: Wakes up the glutes — the big muscles that steady and support your hip. Getting them firing again is the first step toward a hip that feels stronger and carries you with less strain on the joint.

  1. Lie or sit comfortably.
  2. Squeeze your buttock muscles together.
  3. Hold a few seconds, then relax.

Commonly done as 2-3 sets of 10, a few times a day.

  1. Lie on your back and loop a towel around one foot.
  2. Gently straighten the knee toward the ceiling until you feel a light stretch.
  3. Hold, then relax.

Tips:
