How Long Should You Try Injections Before Considering Joint Replacement Surgery
A Guide with Dr. Nathan Cafferky
At a glance
Cortisone injections can reduce inflammation and pain in arthritic joints
Injections should be spaced a minimum of 3 months or 90 days apart
There should be at least 3 months or 90 days between a cortisone injection and total joint replacement surgery
If cortisone injections no longer working becomes a pattern it may be time to discuss knee replacement after cortisone injections, or hip replacement after cortisone injections
Joint pain from arthritis often starts gradually. For many patients the first step is non surgical treatment. Injections are one of the most common tools used to reduce inflammation and maintain function.
But how long should you continue injections before considering surgery?
Below, Dr. Nathan Cafferky, board certified orthopedic surgeon and joint replacement specialist at The Steadman Clinic, explains how to think about timing and when knee replacement after cortisone injections, or hip replacement after cortisone injections becomes the right next step.
The Role of Cortisone Injections
Cortisone injections can decrease inflammation inside the joint and provide meaningful pain relief. For some patients relief lasts several months. For others it may be shorter.
Many patients pursue cortisone injections to delay replacement while continuing to ski, hike, cycle, or travel. That approach can be very reasonable when the joint still responds predictably.
Dr. Cafferky explains, “Injections are a tool. They can calm inflammation and reduce pain, but they do not reverse arthritis.”
The key question is not whether injections work once. It is whether they continue to work consistently.
Proper Timing Between Injections
Spacing matters.
Dr. Cafferky recommends waiting a minimum of 3 months, or 90 days, between cortisone injections in the same joint. Injecting more frequently can increase risks to cartilage and soft tissue quality and may increase overall complication risk.
Equally important, there should be a minimum of 3 months, or 90 days, between a cortisone injection and total joint replacement surgery. This timing helps reduce the risk of infection and optimizes surgical safety.
Thoughtful timing allows injections to be used strategically, not reactively.
When Injections May No Longer Be Enough
Over time, some patients notice that cortisone injections are no longer as effective as they once were. Relief may last only a few weeks. Pain may return more quickly or feel more intense.
Signs it may be time to reconsider the strategy include:
Relief lasts less than six to eight weeks
Pain interferes with sleep or daily activity
You are limiting activities you value
Swelling and stiffness return quickly after each injection
You are scheduling injections every 3 months simply to maintain basic comfort
When cortisone injections no longer working becomes a recurring issue, it often signals advancing joint damage. At that point, knee replacement after cortisone injections, or hip replacement after cortisone injections may provide a more durable solution.
Is There a Limit to How Many Injections
There is no strict lifetime number, but injections should not be used indefinitely as a long term solution. Most surgeons recommend limiting frequency and ensuring at least 3 months between injections.
Dr. Cafferky emphasizes thoughtful decision making.
“The goal is not to chase temporary relief,” he explains. “The goal is to preserve function and quality of life long term.”
If cortisone injections to delay replacement are allowing you to live well and stay active, they may continue to make sense. If they are simply bridging from one painful month to the next, it may be time to discuss knee replacement after cortisone injections or hip replacement after cortisone injections more seriously.
When Surgery Becomes the Smarter Option
Many active patients hesitate to move forward with joint replacement. That is understandable. But modern techniques and recovery protocols have made outcomes highly predictable for appropriately selected patients.
If cortisone injections no longer working and pain is limiting your mobility, surgery is not a failure. It is a progression of care.
For many patients, hip replacement or knee replacement after cortisone injections restores:
Stable pain relief
Improved alignment
More natural movement
The ability to return to meaningful activity
The decision is personal and should be based on symptoms, imaging, overall health, and your goals.
