A cortisone shot will not heal a torn hip labrum, and the pain relief it provides is often limited. In a study of 54 patients with labral tears, only 37% reported meaningful pain reduction at two weeks, and by six weeks that number dropped to just 6%. The average duration of relief was under 10 days. That said, cortisone injections can still play a useful role in managing a labral tear, just not always in the way people expect.
What Cortisone Can and Cannot Do
Cortisone is a powerful anti-inflammatory. When injected into the hip joint, it reduces swelling and quiets the irritated tissue around the tear, which can temporarily ease pain. What it cannot do is repair the torn cartilage itself. The labrum is a ring of tough tissue that lines the rim of your hip socket, and once it’s torn, it stays torn unless surgically repaired. Cortisone addresses the inflammation that a tear causes, not the structural damage.
For some people, that inflammation is the main driver of day-to-day pain, and a shot brings noticeable relief. For others, the pain comes more from the mechanical catching or pinching of the torn tissue during movement, and cortisone does little for that. This partly explains why responses vary so much from person to person.
How Long Relief Typically Lasts
When cortisone does work, relief can last anywhere from a few days to several months. Hospital for Special Surgery notes that an effective shot generally provides 3 to 6 months of benefit. But in patients specifically with labral tears and femoroacetabular impingement (a common companion condition where the hip bones don’t fit together smoothly), the research paints a less optimistic picture. The study mentioned above found an average relief duration of just 9.8 days in that population. The takeaway: cortisone tends to work better for general hip inflammation than for the specific combination of a labral tear with structural bone issues.
Its Real Value: Confirming the Diagnosis
One of the most practical uses of a hip injection isn’t treatment at all. It’s diagnosis. Your doctor may inject a numbing agent alongside (or instead of) cortisone to pinpoint exactly where your pain is coming from. The hip joint sits deep beneath layers of muscle, and pain in the groin or outer hip can originate from the labrum, the joint itself, a nearby tendon, or even the lower back.
If the numbing agent immediately eliminates your pain, that confirms the hip joint is the source. If it doesn’t, your care team knows to look elsewhere. Clinical practice guidelines from the American Physical Therapy Association specifically highlight guided injections as a useful diagnostic tool for chronic hip pain. This information can be critical for deciding whether surgery is the right next step.
What the Procedure Looks Like
The hip joint is deep, so these injections are almost always done with imaging guidance, typically ultrasound or fluoroscopy (a type of live X-ray). This ensures the needle reaches the joint space accurately. In one large series of ultrasound-guided hip injections, 96% of patients reported immediate pain improvement, and the complication rate was low. The most common issue was a temporary flare of hip pain in about 6% of patients, which resolved on its own. Infection was not reported in that series.
After the injection, plan on 1 to 2 days of relative rest. During the first 24 hours, keep activity light to allow the medication to absorb and to watch for any reaction. After 24 to 48 hours, you can begin light weight-bearing activities like cycling or bodyweight exercises, then gradually return to your normal routine as symptoms allow.
Risks of Repeated Injections
A single cortisone injection appears to be relatively safe for the hip joint. A matched-pair study comparing 93 patients who received a hip injection against 93 controls found no significant difference in cartilage deterioration or bone collapse over the following 12 months. Both groups showed identical rates of arthritis progression at 3.2%.
However, that study specifically looked at single injections. The safety of repeated shots is less clear. Lab research has raised concerns about cortisone’s potential to damage cartilage cells over time, which is one reason most orthopedic providers limit how frequently they’ll inject the same joint. If your first shot doesn’t help, getting a second or third is unlikely to produce a different result and may carry additional risk.
What Works Better for Labral Tears
Current clinical guidelines recommend starting with nonsurgical treatment for at least 3 months before considering surgery. The cornerstone of that approach is physical therapy, not injections. A structured rehab program focused on hip stability, core strength, and movement patterns can reduce the load on the damaged labrum and significantly improve pain and function. Cortisone may be offered alongside therapy to make rehab more comfortable, but it’s a supporting player, not the main treatment.
If conservative treatment fails, arthroscopic surgery to repair or reconstruct the labrum is the more definitive option. The diagnostic injection described earlier often plays a key role in that decision: if numbing the joint eliminated your pain, surgical repair of the labrum is more likely to succeed. If it didn’t, surgery may not address the real problem.
Platelet-rich plasma (PRP) injections are sometimes marketed as an alternative, but the research comparing PRP to cortisone has focused primarily on rotator cuff injuries in the shoulder, not hip labral tears. In that context, cortisone provides better short-term relief while PRP shows no clear advantage at any time point. Direct evidence for PRP in hip labral tears remains thin.
