Abstract

Objective: To determine whether musculoskeletal ultrasound (MSUS) abnormalities were associated with thyroid dysfunction. Methods: This study included 109 patients with thyroid diseases, including thyroid dysfunction or autoimmune thyroid disease. Patients were categorized as euthyroid, hypothyroid, or hyperthyroid based on their recent thyroid function tests. To evaluate MSUS, an experienced rheumatologist examined the presence of synovial fluid, synovial hypertrophy, and grade of inflammation in both gray-scale and power Doppler scans of the knee joint. Associations between MSUS abnormalities, thyroid status, visual analog scale (VAS) score for knee pain, and presence of thyroid autoantibodies were investigated. Results: MSUS abnormalities were more frequently associated with hyperthyroid or hypothyroid states than with a euthyroid state. High knee VAS score was significantly associated with overall MSUS severity score regardless of knee osteoarthritis. However, there was no difference in MSUS abnormalities based on the presence of thyroid autoantibodies. Conclusions: Both hypothyroid and hyperthyroid states were associated with MSUS abnormalities and knee arthralgia. MSUS examination may be helpful in uncontrolled thyroid dysfunction and knee arthralgia.
