Cortisone injections vs shoulder surgery: what’s right for your shoulder?

Wondering if cortisone injections are enough to treat your shoulder pain, or if it’s time to consider surgery? Here’s how I help patients make the right decision for their shoulder.
Cortisone injections vs shoulder surgery
Why diagnosis comes first, always
If there’s one topic that comes up almost every day in my clinic, it’s this:
“Should I keep having cortisone injections or is it time to consider surgery?”
For some people, cortisone offers real relief. For others, it’s just a band-aid, and shoulder surgery becomes the better long-term option. In some cases it does not work at all. But the decision isn’t about choosing between a needle and a scalpel; it starts much earlier, with one simple but often overlooked step.
One of the most common issues I see is patients being treated before we know what’s actually causing their pain.
You might have already had an injection based on an ultrasound, or been referred for physiotherapy that didn’t help much. Sometimes even surgery is suggested, all without a clear diagnosis. That’s a recipe for frustration, and worse, delays in proper care.
To make the right call, we need three things:
- A detailed history (your symptoms and how they affect your life)
- A proper shoulder examination
- And an MRI scan
The MRI is what gives us the full picture. It shows soft tissue, tendons, tears, inflammation, the things that don’t show up on X-rays or sometimes even on ultrasound.
If you don’t have an MRI, you don’t know what’s going on.
What cortisone injections shoulder treatment can do (and what it can’t)
Cortisone is a strong anti-inflammatory medicine. When inflammation is the main problem, a well-placed injection can work wonders. It reduces swelling, eases pain, and may even restore movement, sometimes quite dramatically.
Cortisone can help with:
- Shoulder bursitis
- Frozen shoulder syndrome
- Mild tendon inflammation
- Arthritis-related flare-ups
- Symptomatic rotator cuff tearing
In these cases, one or two injections might give you enough relief to avoid surgery altogether, especially if you’re older or have other health concerns that make surgery riskier.
But here’s the key point: cortisone doesn’t fix everything. It won’t repair a torn tendon. It won’t stabilise a shoulder that keeps dislocating. And it can’t reverse joint damage once arthritis is advanced.
When cortisone is a smart option
There’s absolutely a place for cortisone. In fact, I recommend it quite often, but only when the diagnosis makes sense.
It may be a good choice if:
- Your MRI shows inflammation but no major structural damage
- You’re in a painful flare-up and need fast relief
- You’re working through physiotherapy but struggling due to pain
- You’re not fit for surgery or want to delay it for now
- You’ve never had an injection before and want to try a conservative option first
- In situations when surgery cannot be considered or in the older age groups with rotator cuff tearing
In these situations, a cortisone injection isn’t a cure, but it can help you get moving again. That movement, often with support from a physio, is what gets the shoulder back on track.
When injections stop working
If you’ve had multiple injections over several months and still struggle with shoulder pain, it’s time to reassess.
In some cases, repeated injections can delay the right treatment. Worse, if a torn tendon is left untreated, the muscle attached to it may shrink or weaken over time. In these cases, delaying shoulder or orthopaedic surgery might mean the damage becomes harder, or even impossible to repair.
Think of cortisone as a short-term tool, not a long-term plan.
Shoulder surgery might be worth exploring if:
- You’ve had an accident and the pain started suddenly
- There’s a full-thickness rotator cuff tear on your MRI (in active or younger patients)
- You’ve had frozen shoulder for a while without improvement
- The joint feels loose or unstable
- Your sleep, work, or daily function is heavily affected
“It’s not about rushing into surgery; it’s about knowing when conservative care has done all it can.”

Cortisone injections shoulder treatment
Can you avoid surgery completely?
Sometimes, yes, and I’ll always try to help patients avoid surgery if that’s possible. Non-surgical care might include:
Medication (like anti-inflammatories)
- Cortisone injections
- Physiotherapy
- Activity modifications
- Education and monitoring
But the key is timing.
With some shoulder conditions, like a rotator cuff tear after a fall, delaying surgery too long can reduce the chances of a good result. If the tendon pulls back or the muscle shrinks, even the best operation may not restore full function.
So while surgery isn’t always needed right away, ignoring symptoms for too long can close the window for certain treatments.
When shoulder surgery might be the better path
There are some situations where surgery is more effective than injections, especially for structural problems. These include:
- Rotator cuff repair: if the tendon is torn and not healing on its own
- Shoulder stabilisation: if your shoulder keeps dislocating or feels loose
- Arthroscopic surgery: to clean out damaged tissue or remove calcified deposits
- Shoulder replacement: for advanced arthritis or rotator cuff arthropathy
These procedures can restore function, reduce pain, and in many cases, help you return to sports, work, or simply lifting your arm without discomfort.
I’m a shoulder surgeon… but that doesn’t mean I will recommend surgery
It might surprise you, but a large part of my work is helping people avoid unnecessary operations.
I spend time talking with each patient, reviewing their scans, and helping them understand all their options, including what might happen if they decide not to do anything right now.
You don’t have to be “surgical” to see a surgeon.
“My job isn’t to push you into surgery; it’s to help you make a decision that’s right for you.”

What to do if you’re still unsure
If your shoulder pain isn’t improving, and you’ve had one or more cortisone injections without lasting relief, that’s your sign to check in.
You don’t have to jump into surgery. But you do need a proper diagnosis, and a clear understanding of where things stand.
At that point, you can make an informed decision: keep going with conservative care, or look into surgical options with confidence.
If you’re not sure, I also offer second opinions, and Telehealth appointments are available if you’re outside Perth.
