Knee Manipulation (MUA) — Complete Exercise Program

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

A phase-by-phase exercise program used in recovery for knee manipulation (mua). 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

Heel Slides

  2. Slowly slide your heel toward you, bending the knee.
  3. Slide it back down.

Tips:

  • Only go as far as is comfortable.

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

Gently improves how far the knee can bend — often the most important early flexion exercise.

What it helps: Gently improves how far the knee bends — early flexion that makes stairs, chairs, and cars far easier.

  1. Sit in a chair with both feet on the floor.
  2. Place your non-operative leg in front of the operative leg.
  3. Use the non-operative leg to gently help bend the operative knee further.

  2. Tighten your thigh and lift the straight leg a few inches.
  3. Lower slowly.
