A tendon or ligament injection is a treatment that involves injecting medication directly into or around a tendon or ligament. The tendon is the connection between muscle and bone. The ligament is the connective tissue that connects bones together. These injections are commonly used when tendons or ligaments become inflamed or irritated, a condition known as tendinopathy, which can occur due to overuse or injury.

The injection usually includes a corticosteroid or regenerative therapy (like platelet rich plasma, bone marrow or fat) to reduce inflammation and relieve pain. This procedure could help if you’re experiencing pain from conditions like tennis elbow, rotator cuff disorders or Achilles tendinopathy in the calf.

During the procedure, imaging is typically used, like ultrasound, to precisely guide the needle to the affected area. In some cases, imaging is not required for landmark-guided injections, and this will be discussed before the procedure. The injection can provide significant pain relief and help the tendon or ligament heal properly.

Relief can last from several weeks to a few months and beyond, depending on factors like the severity of your condition and your activity level.

There are alternatives to the injection. Physical therapy can strengthen the tendons and ligaments which can improve flexibility. Medications, such as non-steroidal anti-inflammatory drugs (NSAIDS), offer another way to manage pain and inflammation. For some, advanced treatments, like platelet-rich plasma (PRP) injections (or other regenerative therapies)—where a small sample of your blood is used to promote healing—can be effective.

As with any procedure, there are risks, including temporary pain after the injection, infection, and, in rare cases, tendon or ligament weakening. It’s important to rest for a day or two and avoid strenuous activity for about a week to support proper recovery.

Monitoring for signs of redness or swelling is essential. If the injection does not provide relief, alternative treatments, including surgery if needed, may be considered.
