What Is Shoulder Replacement Surgery?

Shoulder replacement, or shoulder arthroplasty, is a surgical procedure that replaces damaged or worn-out parts of the shoulder joint with artificial components.

The goal of the procedure is to restore shoulder function, improve range of motion, and reduce pain when non-surgical treatments no longer provide adequate relief.

It is typically recommended for individuals experiencing chronic shoulder pain, stiffness, and reduced mobility that disrupt daily activities and diminish quality of life.

Types of Shoulder Replacement Surgery

Shoulder arthroplasty procedures vary in complexity, depending on the extent of joint damage and individual patient needs. The main types include:

Illustration of total and reverse shoulder replacement types.

1. Total Shoulder Replacement (Anatomic Shoulder Arthroplasty)

A total shoulder arthroplasty involves replacing both the ball (humeral head) and socket (glenoid) of the shoulder joint with prosthetic components. It is typically recommended for individuals with severe arthritis and intact rotator cuff tendons, as it relies on a functional rotator cuff for stability and movement.

2. Reverse Shoulder Replacement

In a reverse shoulder arthroplasty, the positions of the ball and socket are reversed, allowing the deltoid muscle (the triangular shoulder muscle that lifts the arm) to compensate for a damaged rotator cuff. This technique is primarily used for patients with massive rotator cuff tears, cuff tear arthropathy, or previous failed shoulder surgeries, where a traditional total shoulder replacement may not provide adequate stability.

3. Partial Shoulder Replacement (Hemiarthroplasty)

A shoulder hemiarthroplasty involves replacing only the ball (humeral head) while preserving the natural socket. It is typically considered for isolated humeral head fractures or conditions affecting only the upper part of the joint, where the socket remains healthy.

4. Shoulder Resurfacing

Rather than replacing the entire joint, shoulder resurfacing involves capping the ball (humeral head) with a metal covering to preserve more natural bone. It is a less invasive option for younger or physically active patients with early-stage arthritis, potentially delaying the need for a full shoulder replacement.


When Is a Shoulder Replacement Considered?

Shoulder replacement surgery may be recommended if:

  • Shoulder pain significantly limits daily activities, including reaching, lifting, or sleeping.
  • Conservative treatments, such as physiotherapy, non-steroidal anti-inflammatory drugs (NSAIDs), or cortisone injections, no longer provide sufficient relief.
  • The joint has sustained irreversible damage, such as severe cartilage loss, bone erosion, or joint deformity.
  • Persistent joint instability or weakness affects arm function and mobility.

What Happens During a Shoulder Replacement Procedure?

Shoulder replacement surgery is performed under general anaesthesia and typically takes about two to three hours. The procedure generally involves the following steps:

  1. Incision – An incision (typically 15 to 20 cm) is made over the shoulder to access the joint.
  2. Removal of Damaged Tissue – Damaged bone and cartilage are removed to prepare for the implant.
  3. Implantation of Prosthetic Components – The artificial components (prosthesis) are implanted to restore joint function. The joint is repositioned and aligned, and surrounding soft tissues are adjusted to ensure stability.
  4. Closure and Dressing – The incision is closed, and a sterile dressing is applied to protect the surgical site.

Most patients stay in the hospital for one to two days following surgery.


Potential Risks and Complications

As with any surgical procedure, shoulder replacement carries risks and potential complications that can vary depending on individual health factors. Your surgeon will discuss these risks and others with you before the procedure to ensure you are well-informed.

  • Infection – A rare but serious complication caused by bacteria entering the surgical wound, potentially requiring antibiotics or additional surgery.
  • Implant Loosening or Wear – Although uncommon, prosthetic components can wear down or become loose over time, which may affect joint function and, in some cases, require revision surgery to restore stability or function.
  • Nerve InjuryNerve damage, such as to the axillary or brachial plexus, can occur during surgery. This may result in changes to arm movement and sensation, causing weakness, numbness, or loss of function.
  • Stiffness or Limited Range of MotionJoint stiffness can develop without proper rehabilitation, limiting mobility and function.

Shoulder Replacement Recovery

Recovery after shoulder replacement surgery can vary depending on the type of procedure and individual health factors. A typical recovery process can include:

Recovery Phase Description
First 6 Weeks
  • The arm is immobilised using a sling during the initial recovery period.
  • Pain management includes prescribed medications and cold therapy to reduce swelling and discomfort.
  • Physiotherapy begins with gentle range-of-motion exercises introduced to prevent stiffness and encourage mobility.
6 to 12 Weeks
  • Pain and swelling typically continue to decrease.
  • Strengthening exercises begin to restore shoulder strength and function.
  • Joint stability improves, and patients work on regaining the ability to perform daily activities.
Beyond 3 Months
  • Range of motion and strength continue to improve.
  • Most patients regain functional movement and can resume daily activities, although full recovery may take up to a year. It is important to avoid heavy lifting or high-impact movements during this period.
  • Continued physiotherapy is necessary for strength and flexibility.

How Long Does a Shoulder Replacement Last?

The lifespan of a shoulder replacement typically ranges from 10 to 20 years, with most implants lasting around 15 to 20 years when properly cared for.

Several factors can influence the longevity of the implant, including:

  • Activity Level – Engaging in high-impact activities can increase wear on the implant, potentially shortening its lifespan.
  • Bone Health – Strong, healthy bone around the implant helps maintain its stability and longevity.
  • Postoperative Care – Following rehabilitation protocols and avoiding excessive strain on the shoulder can significantly contribute to long-term success and improved outcomes.

Preparing for Shoulder Replacement Surgery

Before undergoing shoulder arthroplasty, patients typically go through the following steps:

  1. Medical Evaluation – This includes imaging tests such as X-rays or MRI scans to assess joint damage. Some medications may need to be adjusted to reduce surgical risks.
  2. Preoperative Assessment – Discussions are held about anaesthesia, potential risks, and recovery expectations.
  3. Prehabilitation – This may involve physiotherapy to strengthen surrounding muscles and prepare the shoulder for surgery.
  4. Fasting Before Surgery – Patients are typically required to fast for 6-8 hours before surgery to reduce the risk of complications during anaesthesia.

It is important to adhere to pre-surgery instructions to ensure a smoother procedure and a lower risk of complications.

Every patient deserves a treatment plan tailored to their needs. We start with non-surgical approaches before considering more invasive interventions.

Frequently Asked Questions (FAQs)

Full recovery from a shoulder replacement typically takes 6 to 12 months, depending on the type of surgery, rehabilitation progress, and overall health. Most patients regain functional mobility within 3 to 6 months, while strength and flexibility continue to improve over the following months. Consistent physiotherapy and adherence to activity restrictions are essential for optimal healing and long-term results. It is best to consult your orthopaedic specialist for guidance on your expected recovery timeline.

The fastest way to recover from shoulder surgery is to follow a structured rehabilitation plan, maintain good posture, and avoid overusing the operated arm. Early, gentle movement helps prevent stiffness, while consistent physiotherapy restores strength and mobility. Adequate rest, balanced nutrition, and adherence to prescribed activity limits also promote healing. Always follow the advice of your orthopaedic specialist and physiotherapist to support a smooth recovery.

Yes, a shoulder replacement is considered a major surgery as it involves removing damaged joint surfaces and implanting prosthetic components. Despite its complexity, modern surgical techniques and anaesthesia have made the procedure highly reliable with good long-term outcomes. Recovery requires time and rehabilitation, but most individuals experience significant improvements in pain relief and daily function.

The main downsides of a shoulder replacement include potential risks such as infection, nerve injury, stiffness, or gradual implant wear over time. Some individuals may also experience reduced strength during strenuous or overhead movements and, in rare cases, require revision surgery in the future. These complications are uncommon when surgery, rehabilitation, and follow-up care are properly managed. Your orthopaedic surgeon will explain the potential risks and long-term expectations before the procedure.

Shoulder replacement is most commonly recommended for adults aged 60 and above with severe arthritis or joint damage that no longer responds to conservative treatment. However, younger patients with significant injury or degeneration may also benefit. There is no fixed age limit for the procedure as eligibility depends on bone quality, activity level, and overall health. It is advisable to consult an orthopaedic specialist to determine the most appropriate treatment for your condition and age.

Pain after shoulder replacement is expected but typically manageable with prescribed medication and pain control methods. Most individuals report moderate discomfort for the first few weeks, which improves as healing progresses and physiotherapy begins. Advanced anaesthetic techniques and post-operative care have significantly reduced pain levels in recent years. Always follow your surgeon’s and physiotherapist’s pain management plan to support a smoother recovery process.

Shoulder replacement surgery is often considered worthwhile for individuals with severe arthritis or joint damage that causes chronic pain and loss of function. It can significantly improve mobility and quality of life when conservative treatments are no longer effective. However, benefits vary depending on age, bone quality, and adherence to rehabilitation. It is advisable to consult an orthopaedic specialist to determine if the expected improvement outweighs potential surgical risks.

Individuals with active infections, poor bone quality, significant nerve damage, or uncontrolled medical conditions may not be suitable candidates for shoulder replacement. Those with weak or non-functioning deltoid muscles may also experience reduced benefits, particularly in reverse shoulder arthroplasty. Suitability depends on overall health, activity level, and specific joint condition. It is advisable to consult an orthopaedic surgeon to assess whether shoulder replacement or alternative treatments are more appropriate for your situation.

The most common complication following total shoulder arthroplasty is joint stiffness, which may occur if postoperative rehabilitation is delayed or incomplete. Other potential complications include infection, implant loosening, and nerve injury, though these are less frequent. Adhering to rehabilitation protocols and follow-up care greatly reduces these risks.

Shoulder arthroplasty is indicated for advanced arthritis, severe fractures, or irreparable rotator cuff tears that cause persistent pain and impaired joint function. It may also be recommended for conditions such as avascular necrosis or cuff tear arthropathy when conservative treatments fail. The primary goal is to relieve pain and restore shoulder mobility.

Delaying shoulder replacement can result in further joint deterioration, muscle weakening, and reduced bone quality, making surgery more complex and recovery slower. Persistent pain and stiffness may also become more difficult to manage with time. However, the decision to proceed should depend on symptom severity, daily function, and overall health. It is advisable to consult your orthopaedic specialist to determine the most appropriate timing for shoulder replacement based on your individual condition.

After shoulder replacement, individuals are generally advised to avoid heavy lifting, high-impact sports, or sudden overhead movements to protect the implant. Activities involving excessive strain or repetitive force may accelerate wear and reduce implant lifespan. Most individuals can perform daily tasks comfortably once fully recovered. Always follow your surgeon’s long-term activity recommendations to maintain shoulder function and extend implant durability.

Individuals can usually shower within a few days after shoulder surgery once the dressing is waterproof or replaced with a suitable covering. The incision area should be kept clean and dry until it is fully healed to reduce infection risk. Immersing the shoulder in water, such as swimming or soaking, should be avoided until cleared by your surgeon.
