Synopsis Groin pain is common in athletes who participate in multidirectional sports and has traditionally been considered a difficult problem to understand, diagnose, and manage. This may be due to sparse historical focus on this complex region in sports medicine. Until recently, there has been little agreement regarding terminology, definitions, and classification of groin pain in athletes. This has made clear communication between clinicians difficult, and the results of research difficult to interpret and implement into practice. However, during the past decade, the field has evolved rapidly, and an evidence-based understanding is now emerging. This clinical commentary discusses the clinical examination (subjective history, screening, physical examination); imaging; testing of impairments, function, and performance; and management of athletes with groin pain in an evidence-based framework.
