Background: Osteoarthritis (OA) of the hands is a prevalent musculoskeletal diseases with much impact, but knowledge and research results in the field of hand OA are limited. Therefore the DICHOA (Disease Characteristics in Hand OA) initiative was founded in early 2005 with the aim to address key issues and facilitate research in hand OA.
Objective: To review and discuss current knowledge on hand OA with regard to aetiopathogenesis, diagnostic criteria, biomarkers and clinical outcome measures.
Methods: Recommendations were made based on a literature review.
Results: Outcomes of hand OA should be explored, including separately disease activity, damage and functioning from the perspective of patients. All imaging modalities should be cross-validated in hand OA to clinical status, including disease activity, function and performance, biomarkers and long-term outcome. New imaging modalities are available and need scoring systems and validation. The role of biomarkers in hand OA has to be defined.
Conclusion: Future research in hand OA is warranted.
