Cortisone and Corticosteroid Injections Info Evidence
Reviewed by Dr Kieran Hirpara, Specialist Orthopaedic Surgeon Last reviewed
What it is
A cortisone injection is a medicine your doctor places directly into a joint or soft tissue to calm inflammation. Cortisone is a type of steroid that reduces swelling and pain. This helps you move more comfortably while your body heals.
We use these injections for many conditions. You might consider them for ankle arthritis, trigger finger, or carpal tunnel syndrome. They are also used for heel spurs and thumb arthritis. In some cases, we combine cortisone with hyaluronic acid for better pain relief in the ankle.
The injection works by lowering the chemical signals that cause swelling. For trigger finger, we often mix the steroid with lidocaine to reduce pain during the procedure. High-dose injections may provide longer relief and reduce the need for repeat shots or surgery in hand conditions.
Timing matters for some surgeries. A single injection within one year before rotator cuff repair does not affect your final strength or motion. Repeated injections for carpal tunnel syndrome are safe and do not complicate future release surgery.
However, there are risks. In the hip, injections can sometimes worsen arthritis or cause bone damage. For shoulder replacements, more injections are linked to higher risks of stiffness or revision surgery. Your doctor will weigh these factors to decide if this treatment is right for you.
Does it work?
Corticosteroid injections can reduce pain and improve movement for many conditions. They are often used for osteoarthritis, tendon issues, and joint inflammation. The relief you feel depends on the specific problem being treated. For example, combining corticosteroids with hyaluronic acid may relieve ankle pain better than using steroids alone. In cases of heel spurs, injections are a preferred option because many patients report higher satisfaction compared to other conservative treatments.
However, the evidence is not uniform across all conditions. For trigger finger, adding lidocaine to the steroid may reduce pain during the injection, but this difference might not change your long-term outcome. In hand conditions, higher doses of triamcinolone often provide longer relief and reduce the need for repeat injections or surgery. For tendinopathy, platelet-rich plasma (PRP) shows better mid-term results for pain and function than corticosteroids. This means steroids may not be the best long-term solution for every tendon issue.
Timing also matters. A single preoperative injection within one year before rotator cuff repair does not significantly affect failure rates or strength. Similarly, preoperative hip injections do not change ten-year outcomes for hip arthroscopy. Yet, repeated injections for carpal tunnel syndrome are safe and do not worsen future surgery outcomes. Postoperative injections can also help with stiffness after shoulder repair, offering a safer alternative to further surgery for some patients.
It is important to note that high-quality trials are sometimes lacking. Some studies comparing treatments have methodological concerns, such as missing data on inflammation levels or the potential effect of lidocaine. Additionally, disparities exist in who receives these treatments, with minority demographics less likely to be offered injections for hand or shoulder conditions despite similar health profiles. Your doctor will discuss whether an injection is appropriate for your specific situation based on this evidence.
Is it right for you?
Corticosteroid injections often help people with specific joint or soft tissue pain. You might benefit if you have heel spurs, as this treatment is preferred for higher patient satisfaction. It also offers better short-term pain relief than platelet-rich plasma injections. For ankle wear-and-tear arthritis, combining the steroid with hyaluronic acid works better than using the steroid alone. In the hand, high-dose injections provide longer relief and reduce the need for repeat shots or surgery compared to low doses.
However, this treatment is not right for everyone. If you are considering hip arthroscopy for impingement, your previous response to steroids does not predict your long-term results. Similarly, timing an injection within a year before rotator cuff repair does not change your recovery or failure rates. For trigger finger, adding lidocaine to the steroid may hurt more during the shot, though this difference might not matter much later. Repeated injections for carpal tunnel syndrome are safe and do not increase risks for future surgery.
There are important downsides to consider. Hip injections carry risks like rapidly progressive arthritis, bone death, or fractures, though these happen at varying rates. Injections around the pillar of the hand after carpal tunnel release do not prevent pain. You should also know that minority demographics are less likely to receive these injections for hand or shoulder issues, even when their health needs are the same.
Your doctor will discuss whether this fits your situation. We weigh the quick pain relief against potential joint changes. This is a shared decision based on your specific anatomy and goals.
The bottom line
Corticosteroid injections can effectively reduce pain and improve function for many joint and soft tissue conditions. High-dose options often provide longer relief, and combining them with other treatments may offer additional benefit. While generally safe, repeated use carries risks like joint damage or infection, so your doctor will weigh these against your specific needs. We recommend discussing realistic expectations and timing with your care team to ensure this treatment aligns with your long-term health goals.

- Preoperative corticosteroid injection at all studied timepoints was not associated with an increased risk of postoperative deep infection after carpal tunnel release [3].

- Patients who experienced temporary improvement after local corticosteroid injection had better clinical outcomes following endoscopic plantar fascia release for chronic plantar fasciopathy [15].
Comparative Efficacy and Treatment Alternatives

- High-dose triamcinolone injections outperformed low-dose injections across most metrics, including estimated time of relief, rate of repeat injection, and rate of surgery, for soft tissue pathology of the hand [6].
- Platelet-rich plasma (PRP) has superior midterm efficacy compared to corticosteroids for improving pain and functional impairment in tendinopathy [20].
- In patients with adhesive capsulitis, suprascapular nerve blocks provide greater pain relief at 3-4, 6-7, and 12 weeks, greater improvements in shoulder function at 12 weeks, and greater active abduction at 12 weeks compared to intra-articular corticosteroid injections [21].
- Corticosteroid injections are recommended as the preferred option over conservative treatments for heel spurs due to higher patient satisfaction, although both are effective [12].

- Intraoperative corticosteroid pillar injection is not an effective option for preventing pillar pain symptoms after carpal tunnel release surgery [5].
- Repeated corticosteroid injections for carpal tunnel syndrome are safe and do not affect the morbidity of subsequent release [9].
- Postoperative corticosteroid injection is a viable treatment for postoperative stiffness after rotator cuff repair and may serve as a safer alternative to arthroscopic capsular release, particularly in high-risk patients such as those with osteoporosis or at risk of axillary nerve injury [16].
Risks and Adverse Events
- Risks of intra-articular hip corticosteroid injections include rapidly progressive osteoarthritis, osteonecrosis, femoral head collapse, insufficiency fracture, and worsening osteoarthritis, although the incidence rates of these outcomes vary notably [11].
