Shoulder Replacement

Shoulder replacement, also known as shoulder arthroplasty, is a surgical procedure used to treat severe pain and stiffness caused by arthritis, fractures, or damage to the shoulder joint. The shoulder functions as a ball-and-socket joint, where the humeral head (ball) fits into the glenoid cavity (socket) of the scapula. Over time, arthritis or injury can wear away the protective cartilage, causing bone-on-bone friction, pain, and loss of movement. When non-surgical treatments are no longer effective, shoulder replacement surgery is recommended.

There are different types of procedures depending on the condition of the joint:

  • Total Shoulder Arthroplasty replaces both the humeral head and glenoid with artificial implants.
  • Reverse Shoulder Arthroplasty switches the ball-and-socket structure, often used when the rotator cuff is severely damaged.
  • Hemiarthroplasty replaces only the humeral head with a prosthetic implant.
  • Joint Surface Replacement involves resurfacing just the humeral head, commonly for arthritis cases.

This procedure restores movement, reduces pain, and improves quality of life, especially when physiotherapy and medications are not sufficient.

Physiotherapy Before Shoulder Replacement Surgery

Physiotherapy before shoulder replacement is highly recommended as it prepares the shoulder for surgery and improves post-operative recovery. Prehab reduces pain, improves strength, and provides a stronger base for rehabilitation after the operation. Common treatments include:

  • Cryotherapy (ice) and heat therapy for pain relief
  • Pain management techniques
  • Protective taping and bracing
  • Acute symptom control
  • Strengthening of shoulder and surrounding muscles
  • Stretching and massage
  • Guidance on surgery and recovery planning

Symptoms After Shoulder Replacement Surgery

After surgery, your arm will be supported in a protective sling for 4–6 weeks to safeguard the new joint and encourage healing. Common symptoms include:

  • Pain
  • Swelling
  • Bruising
  • Temporary stiffness in the shoulder

Physiotherapy After Shoulder Replacement Surgery

A structured rehabilitation programme is essential for a successful recovery. Physiotherapy focuses on restoring shoulder mobility, strength, and function while following surgical protocols.

Weeks 1–3

  • Cryotherapy and pain management
  • Sling education and safe exercises during use
  • Elbow, wrist, and hand mobility and strengthening
  • Passive and assisted range of motion
  • Isometric strengthening of surrounding muscles
  • Scapular stability training
  • Postural education and wound care

Weeks 4–6

  • Gradual removal of sling
  • Increased passive and active range of movement
  • Scapular stabilising exercises
  • Soft tissue massage and capsule stretching
  • Gentle strengthening programme
  • Closed-chain activities and proprioceptive training
  • Scar management

Weeks 7–12

  • Full active range of motion exercises
  • Progressive strengthening of shoulder and scapular muscles
  • Stretching and soft tissue release
  • Muscular endurance training
  • Functional activity breakdown for daily tasks
  • Closed and open chain strengthening
  • Advanced proprioceptive exercises

Weeks 12+

  • Restoration of full strength and mobility
  • Advanced strengthening throughout full range
  • Sport-specific and functional training
  • Long-term home exercise programme
  • Comprehensive management to maximise return to daily, occupational, and recreational activities

Summary

Shoulder replacement surgery (shoulder arthroplasty) is a highly effective procedure for severe arthritis, fractures, or degeneration of the joint. Successful outcomes depend not only on the surgery itself but also on physiotherapy before and after the operation. With a structured rehabilitation plan, patients can expect restored mobility, reduced pain, and a return to normal activities, including sports and work.
