Physiotherapy Protocol

TOTAL KNEE REPLACEMENT

Phase 1: (0 – 2 weeks)

Goals:

  • Reduce swelling
  • Maintain a general ROM
  • Reduce muscular atrophy
  • Proper use of crutches – ability to navigate stairs and sit to stand functions

Guidelines:

  • Ice/intermittent cryotherapy
  • Elevation of limb
  • Crutches training
  • Lying: Ankle exercises: Pumps (plantar/dorsiflexion)
  • Straight leg raises: Lying supine, lifting leg off bed, hold for 2 sec and lower leg
  • Inner range quads (IRQ): Have a rolled up towel/pillow under knee, straighten knee and lift foot off bed, hold for 3 sec and repeat 4×15
  • Heel slides: slide heel up the bed, gently bending knee, hold and slide back down
  • Towel squeezes: have a rolled up towel under knee, push knee down into the towel, hold for 3 sec and release. Repeat 5×10 times. Place hand on thigh and ensure your muscles tighten adequately each time

Phase 2: (3 – 6 weeks)

Goals:

  • Maintain functional gait status
  • Reduce swelling and effusion
  • Decreasing pain levels

Guidelines:

  • Sitting: Increasing heel slides ROM, with a 2 sec hold at flexion and over pressure from uninvolved leg. Place a plastic bag under foot, so you can slide heel with ease.
  • Standing: Gentle calf and hamstring stretching
  • Mini squat holds: E.g. lean against wall with a small bend in knees, hold position, feeling tension in quadriceps muscle. 4x30sec holds
  • Proprioception: Balance on involved leg on firm surface. Aim for 4×30 sec holds
  • Hip abduction and extension: Standing with involved leg lifted out sideways, hold and return to midline (4×20). Standing with involved leg lifted backwards, hold and return (4×20)
  • Manual Therapy: Patellar mobilisations and soft tissue therapy (quadriceps, calf and hamstrings)
  • Lying: Bridging. Double leg, slow and controlled then progress to single leg as tolerated
  • Hamstring curls in prone. E.g. lying on stomach, lift heel off bed, bend knee to 90 degrees and slowly straighten. Progress to small ankle weight E.g. 5×10

Phase 3: (7 – 12 weeks)

Goals:

  • Scar management
  • Reduction in swelling
  • Normalised gait

Guidelines:

  • Progress mini squats. Increasing time and small pulses.
  • Bridging: Single leg bridges, small dips, hover and return. 4×8-12
  • Lateral stepping (using varied surfaces)
  • Backwards strides: focusing on deceleration
  • Stationary bike: low resistance
  • Proprioception: unstable/soft surface
  • Manual therapy: Soft tissue work

Phase 4: (13+ weeks)

Goals:

  • Gradual return to functional status
  • Scar management
  • Minimal to no pain in activity
  • No swelling

Guidelines:

  • Increase walking, varying surfaces and hills etc
  • Stationary bike: progress resistance
  • Gentle gym workouts: E.g. rowing machine, gentle leg press 0-60 degrees, etc.
  • Gradual return to sport
  • Regular stretching (gastrocs, soleus, hamstrings and quadriceps)
