Anatomic total shoulder rehab

An anatomic total shoulder replacement involves replacing the damaged ball and socket of the shoulder joint with artificial components designed to mimic the natural anatomy. This procedure is typically performed to relieve pain and improve function in patients with severe shoulder arthritis, complex fractures, or other joint disorders.

  • Restore passive and active range of motion
  • Regain strength and function
  • Return to daily activities safely

Expected Recovery Time

MilestoneTimeframe
Sling use (night only), passive exercises0-4 weeks
Full passive range of motion8-12 weeks
Begin strengthening exercises10-12 weeks
Return to most daily activities3-4 months
Return to recreational sports6-12 months
Full recovery12 months

Sling Instructions

  • The sling is very important to use all day and night while any local anaesthetic wears off in the first 48-72 hours after surgery.
  • After that point if you are comfortable you are encouraged not to wear a sling during the day to allow movement to begin
  • Take note of the external rotation instructions below which must be followed when coming out of the sling
  • Use the sling during sleep for the first 4 weeks in case of any abnormal movements
  • If you can sleep and rest with a pillow placed behind your elbow to push it forward this is a safer position for dislocation risk than letting it fall back (rearward)
  • For the first 4 weeks use the sling when travelling outdoors to let others know you have a sore shoulder
  • There should be no further use of a sling at all after 4 weeks
  • Do not lift anything heavy (no more than 500g; e.g. a cup of tea or a can of soft drink) with or without the sling for the first 6 weeks

External Rotation

  • The subscapularis tendon is a rotator cuff muscle at the front of the shoulder joint that is detached and then repaired back to allow surgery to occur
  • Healing the tendon is critical for a successful outcome in terms of shoulder strength, function and joint stability
  • To avoid unnecessary tension on the repaired tendon the following is advised:
    • 0-4 weeks: external rotation to 30 degrees only, stopping if painful
    • 4-6 weeks: up to 45 degrees, stopping if painful
    • 6-12 weeks: up to 60-70 degrees
  • Strengthening can begin from 8-10 weeks onwards but starts with isometric work
  • Full healing takes approximately 3 months
  • Recovery should be guided by a physiotherapist

Phase 1: Early Post-op (0-2 weeks)

Goals

  • Protect surgical repair
  • Control pain and swelling
  • Begin gentle passive motion
  • Prevent stiffness in nearby joints

Instructions

  • Apply ice to shoulder 15-20 minutes every 2 hours as needed for swelling.
  • Keep surgical wound clean and dry.
  • Do not lift objects or bear weight through the surgical arm.

Exercises

  • Hand, wrist, and elbow range of motion (e.g. fist making, wrist flexion/extension)
  • Pendulum exercises (small circles)
  • Passive shoulder forward elevation (with therapist or assistance)
  • Passive external rotation (up to 30 degrees, stopping if painful)
  • Scapular retraction and depression exercises

Phase 2: Protected Passive Motion (2-6 weeks)

Goals

  • Maintain healing
  • Gradually increase passive range of motion
  • Continue to control pain and swelling

Instructions

  • Avoid reaching behind the back or heavy lifting
  • Ice as needed

Exercises

  • Continue Phase 1 exercises
  • Passive and assisted forward elevation and external rotation
  • Begin gentle isometric exercises (without resistance): deltoid, biceps, triceps
  • Scapular stabilization exercises

Phase 3: Active Motion (6-12 weeks)

Goals

  • Progress to active range of motion
  • Improve shoulder mobility
  • Begin light functional use of arm

Instructions

  • Avoid lifting objects heavier than 1-2 kg
  • No forceful stretching or aggressive motion

Exercises

  • Active-assisted range of motion progressing to active motion in all planes
  • Continued scapular stabilization
  • Begin light closed-chain exercises (table slides, wall walks)
  • Continue isometric strengthening

Phase 4: Strengthening (12-24 weeks)

Goals

  • Build strength and endurance
  • Improve functional activities
  • Normalize shoulder mechanics

Instructions

  • Gradual return to normal daily activities
  • Avoid heavy or overhead lifting until cleared

Exercises

  • Progressive resistance training with elastic bands or light weights
  • Scapular and rotator cuff strengthening
  • Proprioception and coordination drills
  • Functional movement exercises

Phase 5: Advanced Strengthening and Return to Activity (6-12 months)

Goals

  • Restore full strength
  • Safely return to recreational and sports activities
  • Maintain shoulder health

Instructions

  • Progress activities as tolerated under guidance
  • Avoid high-impact activities unless cleared by surgeon

Exercises

  • Advanced strengthening routines
  • Sport- or occupation-specific drills
  • Maintenance flexibility program
  • Continue proprioceptive training

When to Contact Your Surgeon

  • Fever above 38°C
  • Redness, drainage, or swelling around the incision
  • Persistent or increasing pain unrelieved by medication
  • Numbness, tingling, or weakness in the arm or hand
  • Unusual clicking or instability in the shoulder
  • Any concerns regarding wound healing or function
