Key Takeaways
- Common signs of a failing shoulder replacement include worsening pain, looseness, instability, and mechanical clicking or grinding.
- Revision shoulder replacement differs from a first-time replacement because the surrounding bone, anatomy, and soft tissue have already been altered by the original surgery.
- Common causes of failure include loosening of the implant without infection, infection itself, instability, implant wear, and fracture of the bone around the implant.
- Catching warning signs early often makes revision surgery simpler and more successful.

Common Signs of Implant Loosening or Instability
A shoulder replacement is designed to relieve pain and restore function, so new or returning symptoms after surgery should not be ignored. According to the American Academy of Orthopaedic Surgeons, a shoulder replacement can fail for a variety of reasons, including infection, loosening, or instability of the implant components, and any of these can result in a loss of function, pain, or both.
Warning signs that a joint replacement may be failing include:
- Persistent or worsening pain, including pain that returns after an initial pain-free period.
- Swelling or warmth around the shoulder, which can indicate inflammation or infection.
- A sense of looseness, giving way, or instability in the joint.
- Mechanical grinding, clicking, or unusual sounds with movement.
- Progressive loss of function or increasing difficulty with daily activities.
How Revision Surgery Differs From a First-Time Replacement
Revision shoulder replacement is fundamentally different from a primary procedure. In a first-time replacement, the surgeon works with the patient's original bone anatomy and soft tissue. In a revision, the amount and quality of healthy bone available to anchor an implant, sometimes called bone stock, has often been reduced by the original implant. Anatomy may have shifted, and the margin for error is smaller. This is one reason revision cases are generally considered more technically demanding than primary shoulder replacements.
For select complex revision cases, Dr. Kamineni utilizes Enovis 3D ProMade custom implant technology, which is fabricated from a CT (computed tomography) scan of the patient's own anatomy rather than relying on standard, off-the-shelf sizes. This approach is designed to account for the altered bone geometry that is common in revision cases.
Why Timing Matters Before More Bone or Tissue Is Lost
Joint replacement failure tends to be progressive rather than sudden. Aseptic loosening, meaning the implant gradually separates from the surrounding bone without any infection present, is one example. The longer this goes unaddressed, the more bone loss can occur, which in turn can make revision surgery more complex. Similarly, an unaddressed infection can spread and cause additional damage to the joint and surrounding tissue over time.
This is why evaluating symptoms early, rather than waiting to see if they resolve on their own, can meaningfully affect the complexity of any eventual revision procedure and the range of options available.
What a Revision Evaluation Involves
A thorough evaluation for a suspected failing shoulder replacement typically includes:
- A detailed history of symptoms, including when they started and how they have progressed.
- Physical examination assessing range of motion, stability, and strength.
- Imaging, which may include X-rays and advanced imaging to evaluate implant position and bone quality.
- Laboratory workup when infection is a concern, since infection can be difficult to detect on imaging alone.
Primary vs. Revision Shoulder Replacement
| Factor | Primary Shoulder Replacement | Revision Shoulder Replacement |
|---|---|---|
| Available healthy bone | Native, unaltered anatomy | Often reduced by the prior implant |
| Surgical complexity | Standard | Higher, due to altered anatomy |
| Common causes for surgery | Arthritis, rotator cuff tearing, fracture | Loosening, infection, instability, wear, fracture around the implant |
| Implant options | Standard off-the-shelf systems | May include custom implants for complex bone loss |
| Evaluation focus | Diagnosing the underlying joint condition | Identifying the specific cause of implant failure |
A Practice Built Around Complex Cases
Roughly half of Dr. Kamineni's practice involves patients referred by other orthopaedic surgeons for cases that require additional expertise, including revision joint replacement. As a double fellowship-trained surgeon board-certified in both the United States and England, he brings experience with the full spectrum of primary and revision shoulder care to patients in Mount Carmel and Olney, Illinois.
Don't Wait If Your Shoulder Replacement Doesn't Feel Right
Persistent pain, instability, or clicking after a shoulder replacement are signs worth having evaluated promptly, even if the original surgery was performed elsewhere. Early evaluation can help determine the cause and the most appropriate path forward.

Frequently Asked Questions
What are the first signs of a failing shoulder replacement?
Early signs often include new or worsening pain, especially pain that returns after a period of relief, along with swelling, a sense of instability, or clicking and grinding sensations during movement.
How long do shoulder replacements typically last before revision is needed?
Implant longevity varies based on factors including patient activity level, bone quality, and overall health. While many shoulder replacements last for years without issue, some patients require revision sooner due to loosening, infection, or instability.
Is revision shoulder replacement surgery near me more complicated than my first surgery?
Yes, in most cases. Revision surgery involves previously altered bone and soft tissue, which generally makes it more technically demanding than a first-time replacement. Choosing a surgeon experienced specifically in revision cases is important.
Can a failing shoulder replacement be caused by infection even years after surgery?
Yes. An infection around the implant, known as a periprosthetic infection, can occur shortly after the original surgery or years later, and it does not always present with obvious symptoms, which is why laboratory testing is often part of a thorough evaluation.
What should I do if I think my shoulder replacement is failing?
Schedule an evaluation with an orthopedic surgeon experienced in revision joint replacement. Early assessment through imaging and physical examination helps identify the cause and the most effective treatment path.
