Total Shoulder Arthroplasty (Delayed) Protocol (Patients with Rotator Cuff Involvement)

Total Shoulder Arthroplasty (TSA) is a highly successful procedure for relieving pain and restoring function in patients with severe shoulder arthritis. However, when a patient presents with significant rotator cuff involvement—such as a concurrent rotator cuff repair, poor quality cuff tissue, or a history of cuff pathology—the postoperative rehabilitation must be modified. This delayed protocol is specifically designed to protect the healing rotator cuff during the early weeks, slowly introducing movement to ensure long-term joint stability and optimal functional outcomes. Under the direction of Dr. Christian Veillette at Toronto Western Hospital and Women's College Hospital, this protocol outlines a safe, criteria-based progression for recovery.

Phase 1: Protection & Delayed Mobilization (Weeks 0-6)

The primary focus of this phase is to protect the healing rotator cuff and the joint replacement, manage pain and swelling, and maintain passive range of motion within safe limits.

• Goals:
  • Protect the joint replacement and the healing rotator cuff repair.
  • Control post-operative pain, inflammation, and swelling.
  • Achieve passive shoulder flexion/scaption to 90 degrees and passive external rotation to 20-30 degrees in the scapular plane.
  • Maintain full active range of motion of the elbow, wrist, and hand.
• Precautions & Restrictions:
  • Sling must be worn at all times (including during sleep) except when performing hygiene and designated exercises.
  • No active movement of the surgical shoulder (no active elevation, abduction, or rotation).
  • No passive external rotation beyond 30 degrees to protect the subscapularis and cuff.
  • No weight-bearing on the surgical arm (e.g., pushing up from a chair).
  • Avoid sudden, jerking movements or reaching behind the back.
• Suggested Exercises:
  • Gentle passive shoulder flexion and scaption to 90 degrees (performed by a physical therapist or using the non-surgical arm).
  • Gentle passive external rotation to 20-30 degrees in the scapular plane.
  • Pendulum (Codman’s) exercises (small circles, completely passive).
  • Active range of motion for the elbow, wrist, and hand.
  • Gentle scapular shrugs and retractions (active, without resistance).
• Criteria to Progress:
  • At least 6 weeks post-surgery.
  • Adequate healing of soft tissues and rotator cuff.
  • Passive range of motion targets met (flexion to 90°, external rotation to 20-30°) without significant pain.
  • Pain and inflammation are well controlled.

Phase 2: Active-Assisted & Early Active Range of Motion (Weeks 6-12)

In this phase, we begin to gradually discontinue the sling and introduce active-assisted and early active movement, focusing on restoring motion while avoiding stress on the cuff.

• Goals:
  • Gradually discontinue the use of the sling.
  • Restore passive and active-assisted range of motion (AAROM).
  • Initiate gravity-minimized active range of motion (AROM).
  • Re-establish normal scapulohumeral rhythm.
• Precautions & Restrictions:
  • Sling should be completely discontinued by week 6 or as instructed.
  • No lifting of objects heavier than 1-2 pounds.
  • Avoid resisted shoulder movements (no bands, weights, or manual resistance).
  • Avoid sudden, rapid movements or heavy pushing/pulling.
• Suggested Exercises:
  • Active-assisted shoulder elevation using a cane/wand or pulley (in the scapular plane).
  • Active-assisted external rotation to 40 degrees.
  • Supine active shoulder elevation (gravity-minimized).
  • Standing table slides (forward and abduction).
  • Wall slides (assisted).
  • Prone scapular stabilization (retraction, depression) without resistance.
• Criteria to Progress:
  • Active-assisted shoulder flexion/elevation to 120 degrees.
  • Active-assisted external rotation to 40 degrees.
  • Stable active movement without muscle guarding or significant compensatory shrugging.

Phase 3: Active Range of Motion & Early Strengthening (Weeks 12-16)

This phase introduces gentle, pain-free strengthening of the rotator cuff and scapular stabilizers, alongside achieving full active range of motion in all planes.

• Goals:
  • Restore full active range of motion (AROM) in all planes.
  • Initiate gentle, pain-free strengthening of the rotator cuff and scapular stabilizers.
  • Improve shoulder endurance and muscle coordination.
• Precautions & Restrictions:
  • No heavy lifting (limit to 5-10 pounds).
  • Avoid overhead lifting or carrying heavy loads.
  • Do not perform exercises that cause sharp or persistent shoulder pain.
• Suggested Exercises:
  • Standing active shoulder elevation and abduction (gradually progressing from gravity-minimized).
  • Side-lying active external rotation (no weight or very light 1-pound dumbbell).
  • Standing internal and external rotation with light resistance bands (yellow band, tension-free arcs).
  • Light scapular strengthening (rows, lat pull-downs with light bands).
  • Prone rows and prone horizontal abduction (neutral rotation).
  • Standing serratus punch (against wall or with light band).
• Criteria to Progress:
  • Active shoulder range of motion near pre-injury baseline or contralateral side.
  • Able to perform light resisted exercises without pain flare-ups.
  • Proper scapulohumeral mechanics during active movement.

Phase 4: Advanced Strengthening & Functional Return (Weeks 16-24+)

The final phase focuses on maximizing strength, power, and endurance of the shoulder girdle, preparing the patient for return to recreational and daily activities.

• Goals:
  • Maximize strength, power, and endurance of the shoulder girdle.
  • Re-establish dynamic joint stability.
  • Return to light recreational sports, manual tasks, and occupational duties.
  • Establish a long-term home maintenance exercise program.
• Precautions & Restrictions:
  • Progress load and volume gradually.
  • Avoid high-impact loading or sudden, uncontrolled heavy lifting.
  • Always maintain correct posture and biomechanics during exercises.
• Suggested Exercises:
  • Progressively loaded rotator cuff strengthening (internal/external rotation with dumbbells or bands).
  • Proprioceptive Neuromuscular Facilitation (PNF) diagonal patterns.
  • Push-up plus (cuff and scapula stabilization) against a wall or counter, progressing to floor as tolerated.
  • Dynamic stabilization drills (e.g., ball stabilization, perturbation drills).
  • Sport-specific or work-specific task simulations.
• Criteria to Progress:
  • Completion of phase-based strengthening without pain.
  • Contralateral shoulder strength matching within 80-90%.
  • Independent home program compliance.

These guidelines represent a standard rehabilitation protocol. Individual recovery rates vary significantly depending on the size of the repair, bone/tissue quality, and general patient health. Your surgeon may modify this protocol specifically for you.
