How to do it

You need: A strap, belt, or long towel.

Sit on a firm bed or the floor with both legs out straight. Loop a strap around the sole of the operated foot, or rest your other ankle across it to help.

  1. Slide the heel of the operated leg slowly toward your bottom, letting the strap or your other leg do the pulling.
  2. Keep the muscles of the operated leg relaxed as the knee bends.
  3. Stop where you feel a firm but comfortable stretch and hold it for a moment.
  4. Guide the leg slowly back out straight, still using the strap or your other leg for control.

Form cues

  • The assistance does the work while the operated thigh stays soft.
  • You feel a gentle pull around the knee, not a sharp or pinching pain.
  • The bend and the return are both slow and even.

Common mistakes

  • Forcing the knee past a gentle stretch into real pain.
  • Bouncing at the end of the bend to gain more range.
  • Letting the leg flop back out straight instead of controlling it.

Safety: Stop and message your physio if a stretch leaves lasting pain, or the knee becomes hot, red, and swollen, or the wound starts to leak.
