Peroneal tendonitis is inflammation of the tendons in the ankle, causing pain and swelling. It can be chronic or acute and is often caused by repetitive use or sudden stress. Treatment includes physical therapy, rest, and anti-inflammatory drugs. If left untreated, it can develop into tendinosis.
Peroneal tendonitis is a condition that affects the tendons in the ankle. The symptoms of peroneal tendonitis are chronic or acute, depending on how they first occur. Chronic tendonitis symptoms occur over a long period of time and are often caused by repetitive use. Acute symptoms occur suddenly. These symptoms can involve pain, swelling and in acute cases weakness of the ankle.
The peroneal tendons are two tendons that run down the outside of the ankle bone. One of these tendons attaches to the midfoot while the other runs under the foot. Both peroneal tendons are used to stabilize the ankle and foot and are essential for any activity that involves walking or running. For this reason, peroneal tendonitis can often be a difficult condition to treat as the tendons are constantly put under stress.
Peroneal tendonitis occurs when one or both tendons become inflamed. In most cases, this is caused by repetitive movements such as during some sports. A sprained ankle can also put tendons under sudden stress, which can cause tendonitis. The main symptoms of peroneal tendonitis are pain and swelling. Chronic peroneal tendonitis can be painful but without the swelling, however.
Diagnosing peroneal tendonitis is important because the condition is often misdiagnosed and incorrectly treated. A surgeon or doctor should look at the type of pain, warmth, and stability in the ankle to properly diagnose the problem. In some cases, scans may be needed to rule out other potential causes.
Treatment for peroneal tendonitis may require surgery, but in most cases, conservative methods will resolve the problem. To begin with, physical therapy, including stretches, ice, and rest, will be used to control pain and improve joint health. Immobilization of the ankle joint may be required to allow the tendons to heal without re-injury. Anti-inflammatory drugs are also commonly used to control swelling and reduce overall recovery time.
Over time, tendonitis can develop into tendinosis, a degeneration of the tendon. When a tendon becomes damaged in this way, it can be difficult for it to heal because tendons have a reduced blood supply compared to muscles. Symptoms of peroneal tendinosis include pain on the outside of the ankle and a high arch.
