The objective was to identify all outcome measures used in studies on trapeziometacarpal osteoarthritis (TMC OA) and evaluate their measurement properties. In a two-step systematic literature review, we first identified studies including TMC OA patients and extracted all outcome measures. They were categorized according to the Outcome Measures in Rheumatology (OMERACT) core set for OA including five dimensions: pain, physical function, global assessment, imaging, and quality of life (QoL). Secondly, we retrieved articles on the measurement properties of the identified outcome measures for TMC OA patients. First, 316 articles including 101 different outcome measures were identified, addressing the OMERACT pain and function domains most frequently but under-representing QoL. Second, 12 articles investigating measurement properties of 12 outcome measures were identified. The methodological quality of these studies was poor to fair, implying that based on the literature no recommendations to use any of the outcome measures can yet be made.
