COMPLEX SHOULDER PROBLEMS
Failed Shoulder
Replacement
Most shoulder replacements provide excellent pain relief and function. However, when a shoulder replacement is painful, unstable, stiff, or not functioning as expected, a careful evaluation is essential. Not every problem requires surgery—but every problem deserves a clear diagnosis.

What Does “Failed” Mean?
A shoulder replacement is considered "failed" when it does not provide the expected improvement in pain, motion, stability, or function. This may occur shortly after surgery or develop gradually over time.
Importantly, not every painful shoulder replacement has truly failed—and not every problem requires revision surgery.
Dr. Streit's Perspective
"Failure" is a strong word. My goal is to understand exactly what you're experiencing and why. In many cases, there is a specific, treatable cause. The key is making the correct diagnosis before recommending any additional surgery.
Common Problems After Shoulder Replacement
Persistent Pain
Pain that never improved or returned after an initial recovery period.
Instability
The shoulder feels loose, shifts, or dislocates.
Stiffness
Limited motion that interferes with daily activities.
Weakness
Difficulty lifting the arm or performing routine tasks.
Loss Of Function
The shoulder does not perform the way you expected after surgery.
Unexpected Recovery
Recovery has been slower or more difficult than anticipated.
Why Does Shoulder Replacement Fail?
Implant Loosening
Components may loosen from the bone over time.
Infection
Even subtle infections can cause pain and dysfunction.
Rotator Cuff Failure
Changes in the rotator cuff can alter shoulder mechanics.
Instability
The shoulder may not be properly balanced.
Component Position
Implant alignment can affect long-term function.
Scar Tissue
Stiffness may result from postoperative scarring.
The Most Important Step: Diagnosis
Before considering revision surgery, it is essential to determine the exact cause of the problem. This often requires a detailed evaluation including imaging, laboratory testing, and careful physical examination.
History
Understanding your previous surgery and recovery.
Imaging
X-rays and CT scans evaluate implant position and bone.
Lab Testing
Used when infection is a concern.
What I Tell My Patients
"The biggest mistake in revision surgery is operating before understanding the problem. My first job is to figure out exactly why your shoulder isn't working the way it should."
Do All Failed Shoulder Replacements Need Surgery?
No. Some problems can be managed without surgery, including physical therapy, medications, or observation. Revision surgery is recommended only when it offers a clear path to improving pain, function, or stability.
When Is Revision Surgery Considered?
Persistent Pain
When pain significantly limits daily life.
Instability
Recurrent dislocation or a feeling of looseness.
Mechanical Failure
Loosening or implant-related problems.
Infection
Requires specialized treatment.
Loss Of Function
When expected recovery has not been achieved.
Patient Goals
When function does not match expectations.
