The ankle joint is prone to various injuries such as fractures, sprains and arthritic conditions. Individuals who engage in activities involving abrupt direction changes and running on uneven surfaces face a higher risk for ankle injuries. Ankle synovitis involves the inflammation of the synovium that triggers swelling and pain. The inflammation can result to excess fluid that leaks into the joint which result to lack of nutrients to the surrounding surfaces, degradation of the cartilage and joint instability. Take note that the inflammation can also lead to swelling of the membrane, thus placing additional pressure on the joint surface.
Causes
Ankle synovitis can be due to previous injuries to the joint such as fractures or sprains. These injuries can result to acute damage to the synovial membrane or cause misalignment or imbalance of the bones which leads to a chronic condition.
Chronic misalignment or imbalance can lead to irritation of the synovium. It can also be caused by an infection either viral or bacterial in the area. Gout or rheumatoid arthritis can also cause the condition.
What are the signs and symptoms?
Ankle synovitis can be accompanied by pain and warmth in the ankle joint. The pain can range from a mild ache to a sharp burning pain. Inflammation and swelling deep within the ankle joint can be linked to ankle synovitis.
This may or may not be visible on the outer part of the joint. There is reduced range of motion and loss of function that can occur depending on the degree of pain and inflammation. Once excess fluid is released into the joint or severe swelling occurs inside the synovium, tightness can be felt in the joint, thus reducing the range of motion.
Treatment
The treatment for ankle synovitis typically involves application of an ice pack, rest and NSAIDs to help minimize the inflammation and stress on the synovial membrane. Heat can be used later to improve the function and minimize the stiffness within the joint. An injection of corticosteroid and a walking boot might be required for severe injuries.
Treatment of the condition that triggered the inflammation is needed to prevent it from occurring again. It is best to consult a physical therapist or sports professional. In most cases, orthotic devices help correct imbalances and structural issues within the foot. Ankle synovitis typically responds in 3-5 weeks of treatment.
Preventive measures
The prevention of ankle synovitis can be difficult due to the secondary nature of this injury, but avoiding diseases or injuries that lead to this condition will minimize the likelihood of developing synovitis.
- Perform proper warm-up exercises to prepare the muscles and joints. This will help minimize the effects of current muscle imbalances and prepares the muscles to support and protect the joints during activity.
- Avoid activities that trigger the pain.
- Good flexibility and strength will minimize most injuries. By increasing overall strength, it helps provide a protective support system for bones and joints by strengthening the muscles and tendons.
