Most rotator cuff repairs heal well. But for a proportion of patients, pain or weakness returns, or never fully goes away, after surgery. If that’s where you’re at, it’s worth understanding what a failed repair actually means, why it happens, and what the options look like from here.
What does a “failed” rotator cuff repair mean?
A failed repair generally refers to one of two things:
- The tendon has re-torn. The repair held initially, but the tendon has pulled away from the bone again, partially or completely.
- The repair never healed properly. Imaging shows the tendon didn’t reattach securely in the first place, even without a clear re-injury.
Either way, the result is similar: pain, weakness, and reduced shoulder function that doesn’t match what would normally be expected at that stage of recovery.
Signs your rotator cuff repair may have failed
- Pain that returns or worsens after an initial period of improvement
- Ongoing weakness lifting the arm, particularly overhead
- A grinding or catching sensation in the shoulder
- Loss of range of motion that isn’t improving with physiotherapy
- Night pain that persists well beyond the expected recovery window
None of these on their own confirm a failed repair. They’re signs worth raising with your surgeon, who will usually order imaging, typically an MRI or ultrasound, to see what’s actually happening with the tendon.
Why do rotator cuff repairs fail?
A number of factors influence whether a repair holds:
- Tear size and tissue quality. Larger tears, and tendons with poor tissue quality going into surgery, carry a higher re-tear risk.
- Age. Tendon healing capacity decreases with age, which is part of why re-tear rates are higher in older patients.
- Smoking. Smoking is one of the more modifiable risk factors and is consistently linked to poorer tendon healing.
- Rehab too fast, too soon. Loading the repair before the tendon has biologically healed, even with good intentions, is a common contributor.
- Re-injury. A fall or sudden load on the arm during the healing phase can retear a repair that was otherwise progressing well.
What are the options if a repair has failed?
The right path depends on the size of the re-tear, the quality of the remaining tendon, and your goals for the shoulder.
Non-surgical management
For some patients, particularly those with smaller re-tears or lower functional demands, physiotherapy focused on the surrounding muscles can restore useful function without further surgery.
Revision rotator cuff repair
Where the tendon and surrounding tissue are still repairable, a revision surgery aims to re-attach the tendon, sometimes with additional techniques to support healing, such as tissue grafts.
Alternative procedures
For larger, irreparable tears, other options exist, including tendon transfers or, in appropriate cases, reverse total shoulder replacement. These are more involved decisions and depend heavily on individual circumstances.
Common questions about failed rotator cuff repairs
How common is it for a rotator cuff repair to fail? Re-tear rates vary depending on tear size and patient factors, and are higher for larger tears and older patients. It’s a recognised, if not universal, outcome of rotator cuff surgery.
How soon can a rotator cuff repair fail? Most re-tears happen within the first few months after surgery, while the tendon is still healing, though some occur later, particularly after a new injury.
Do I need another surgery if my repair failed? Not necessarily. Some failed repairs are managed well with physiotherapy alone. Whether revision surgery is appropriate depends on the size of the re-tear and your functional goals, which is best assessed in person.
Is a revision rotator cuff repair as effective as the first surgery? Revision repairs can restore good function, though outcomes are generally more variable than a first-time repair, given the tissue quality involved.
Discuss your shoulder with Dr Chris Bell
If your shoulder hasn’t recovered the way you expected after rotator cuff surgery, it’s worth getting it properly assessed rather than assuming it’s simply slow to heal. Book a consultation with Dr Chris Bell at Bell Orthopaedics, Woolloongabba and Sunnybank, Brisbane.
