What to do when a cortisone shot stops working for knee arthritis
If a cortisone shot no longer relieves knee arthritis pain, the next step is not automatically another injection or surgery.

First, make sure nothing important has changed
Before choosing another elective treatment, seek prompt medical evaluation if the knee is newly hot, red or rapidly swollen; if you have fever; if you suddenly cannot bear weight; or if the knee locked after an injury. Those features can point to infection, fracture, crystal arthritis, or another problem that should not be managed as routine osteoarthritis.
Why a cortisone shot may stop helping
| Possible explanation | Why it changes the next step |
|---|
| The medication wore off | Expected with a temporary treatment; reassess goals before repeating it |
|---|
| Arthritis has progressed | Temporary treatments may no longer provide enough relief for the degree of limitation |
|---|
| Pain is not mainly from the joint | Hip or spine disease, tendon pain, stress fracture, and other diagnoses need different treatment |
|---|
| The injection missed the joint | Image guidance may matter in selected patients, especially after a technically uncertain injection |
|---|
| A flare has a different cause | Marked swelling, crystal disease, or inflammatory arthritis may need aspiration or a different workup |
|---|
The realistic next options
| Option | Most useful when | Main limitation |
|---|
| Exercise and physical therapy | Strength, motion, confidence, or activity tolerance can still improve | Requires consistent participation; not instant relief |
|---|
| Medication | Symptoms remain intermittent and medication is medically safe | NSAIDs are not appropriate for everyone |
|---|
| Unloader brace or cane | Pain is compartment-specific or walking load is the main trigger | Fit and adherence determine usefulness |
|---|
| Gel injection | A shared decision after other options fail and coverage is available | Average benefit is inconsistent |
|---|
| PRP | Cash cost is acceptable and uncertainty is understood | Not proven to regrow cartilage; preparations vary |
|---|
| Genicular nerve RFA | Temporary pain reduction is the goal and surgery is not desired or appropriate | Does not treat the mechanical arthritis |
|---|
| GAE | An emerging option is being considered after conservative care | Sham-controlled evidence is conflicting; coverage may be limited |
|---|
| Partial or total replacement | Pain and disability are substantial and nonsurgical care is no longer enough | Recovery, complication, and implant-longevity tradeoffs |
|---|
How to choose among them
- Confirm that the arthritic knee—not the hip, spine, or another structure—is the main pain source.
- Define whether you need a short bridge, want to delay surgery, cannot have surgery, or want the most durable correction available.
- Do not repeat treatments by habit. A well-placed injection that gave no meaningful relief is less attractive to repeat unless there is a clear reason the result may differ.
- Compare cost, insurance, visits, recovery, uncertainty, and what happens if the next option fails.
- Discuss surgery based on life impact, not an arbitrary number of failed injections.
Questions for your next visit
- Is knee arthritis clearly the main source of my pain?
- Was the prior injection definitely inside the joint?
- Which option is most likely to change my function—not only my pain score?
- Is this a bridge, an alternative to surgery, or a definitive treatment?
- What will we do next if this option does not work?
