Post-op recovery First 2 weeks Date
Goals
  • Protect the knee and surgical incision
  • Recover from swelling and inflammation
  • Control of post-surgical pain
 
Precautions
  • Walk short distances only
  • Use crutches for support
 
Recommendations
  • Weight bear as tolerated using crutches for support
  • Rest and elevate as required
  • Ice the knee as desired – particularly in the first week
  • Range of motion exercises of ankle
  • Range of motion exercises of hip
  • Gentle movement of the knee from full extension to maximum flexion as pain and swelling allows
 
Suggested exercises
  • Static quads contraction
  • Supine straight leg raise
  • Ankle pumps
  • Supine bed supported knee bend
  • Sitting supported knee bend
  • Sitting knee extension stretch – foot on floor
  • Supine knee extension – foot elevated/supported
  • Standing knee extension
 
Phase 1 Week 2 to week 6  
Goals
  • Begin training to walk normally
  • Fully weight bear with crutches for support as required
  • Increase range of motion
  • Begin strengthening
 
Precautions
  • Avoid long walks, cycles or exercise sessions that inflame the knee – shorter sessions – three times a day – is better. Allow the knee to settle and rest between sessions.
 
Recommendation
  • When standing with your weight on the leg, push the both knees back into full extension – hold for 20 seconds (do this often)
  • When flexing your knee as far as you can – hold for 20 seconds
  • If able to – begin using an exercycle – short and gentle to begin with
  • Hip and gluteal muscle strengthening
  • Ankle range of motion and strengthening
  • When stable and safe – use one crutch (opposite to operated knee)
  • When stable and safe and gait improving, discard the use of crutches (better to walk well with crutches than lurch and limp without)

 

 
Suggested exercises
  • Supine straight leg raise
  • Sitting supported knee bend
  • Supine knee extension – foot elevated/supported
  • Standing knee extension
  • Sitting knee extension stretch – foot on floor
  • Wall slide mini squat
  • Single leg stance – knee straight, knee flexed
  • Step ups
  • Double calf raises
  • Side leg raise – knee straight, knee flexed

  • When standing with your weight on the leg, push the knee back into full extension – hold for 20 seconds (do this often)
  • When flexing your knee as far as you can – hold for 20 seconds
  • Passive stretching to achieve full extension and flexion
  • Hip and gluteal muscle strengthening
  • Ankle range of motion and strengthening
 
Suggested exercises
