Your 6 Must-Do Exercises Before & After Knee Replacement Surgery

A Total Knee Replacement (TKR) is a huge step toward living pain-free! But your success depends 50% on the surgery and 50% on your commitment to physiotherapy.

Our physiotherapists at Veritas Rehabilitation Hospital confirm that the best outcomes begin before your surgery and continue strong afterward. We’ve broken down the 6 essential knee replacement exercises that will speed up your recovery and get you back on your feet faster.

The 6 Essential Knee Replacement Exercises

Perform 10 repetitions of each exercise, twice a day, every day. Consistency is the secret to a fast recovery!

1. Ankle Pumps

  • Goal: Improve circulation (blood flow) to prevent clotting and reduce swelling. This is essential right after surgery!

  • Position: Lying down or sitting with your leg straight or slightly bent.

ActionHow to Do It
Pump DownSlowly point your toes away from you, like a ballerina.
Pump UpSlowly pull your toes up toward your head until you feel a gentle stretch in your calf.

2. Quad Sets (Knee Presses)

  • Goal: Strengthen the quadriceps (thigh muscle) and maintain the ability to straighten your knee (full extension).

  • Position: Lying on your back with your legs straight.

ActionHow to Do It
ContractTighten the muscle on top of your thigh as hard as you can. Feel your kneecap pull upward.
Press DownPush the back of your knee down into the bed or floor.
HoldHold the contraction for 5 seconds, then relax.

3. Straight Leg Raises (SLR)

  • Goal: Build strong hip and thigh muscles to control your new joint while walking.

  • Position: Lying on your back. Bend your non-surgical leg slightly for support.

ActionHow to Do It
PrepTighten your thigh muscle (perform a Quad Set first).
LiftKeeping the surgical knee perfectly straight, lift the entire leg off the bed. Lift it only until it’s level with your bent leg.
LowerLower the leg slowly and gently back to the bed.

4. Heel Slides

  • Goal: Increase knee flexion (bending) range of motion. This is the main focus of early TKR recovery!

  • Position: Lying on your back with legs extended.

ActionHow to Do It
Slide UpKeeping your heel in contact with the bed, slowly slide it up toward your buttocks, bending your knee as far as possible.
ReturnSlowly slide your heel back down to the starting position.

5. Short Arc Quads (Mini Kicks)

  • Goal: Strengthen the quadriceps without full knee extension, reducing strain on the new joint.

  • Position: Lying on your back. Place a thick pillow or firm roll (like a coffee can wrapped in a towel) directly under your knee.

ActionHow to Do It
Kick OutSlowly lift your foot off the bed and straighten your bent knee completely.
HoldHold the straight position for 5 seconds.
ReturnSlowly lower your foot back down to the bed and relax.

6. Seated Knee Range of Motion

  • Goal: Improve dynamic range of motion (bending and straightening) using gravity.

  • Position: Sit in a firm chair where your feet can slightly clear the floor.

ActionHow to Do It
BendLet your foot hang down, bending your knee as far as you comfortably can.
StraightenUse your thigh muscle to lift your foot and straighten your knee completely (aim for a completely straight lock).

Pro Tip from Veritas Physio: If you are too tall and your feet touch, sit on a pillow to elevate yourself. Focus on getting the knee all the way straight every time.

These six exercises are the foundation, but a complete recovery requires expert guidance.
