Introduction: Little is known about the development of specific acromioclavicular joint osteoarthritis. Its histological alterations are controversial and radiological alterations are seen in asymptomatic people. Objective: Evaluate histologically the subchondral bone of the distal clavicle and to analyze magnetic resonance imaging in patients with painful and non-painful acromioclavicular joint osteoarthritis. Methods: An observational, analytical and cross-sectional study with a control group was conducted. Were analyzed a total of forty-one patients between August 2018 and June 2019. Group 1 allocated patients with pain in the acromioclavicular joint (symptomatic osteoarthritis) and group 2 was formed of patients without pain in the acromioclavicular joint (asymptomatic osteoarthritis). Results: Of the 15 patients with acromioclavicular joint pain (group 1), 12 were female, 13 presented edema on magnetic resonance imaging in the distal clavicle and 9 had subchondral bone edema on histological evaluation. Patients with acromioclavicular joint pain had significantly longer shoulder pain when compared to patients without pain. Women were 7.000 times more likely to have acromioclavicular joint pain compared to men. Patients with edema on magnetic resonance imaging showed a 9.389 times greater chance of presenting pain in the acromioclavicular joint in comparison with patients without edema. Conclusion: Females had a higher chance of presenting acromioclavicular joint pain compared to males. Patients with edema on magnetic resonance imaging were more likely to present pain when compared to patients without edema. Patients with acromioclavicular joint pain had significantly longer shoulder pain in comparison with patients without pain. Subchondral bone edema at histological evaluation was more frequent in patients with pain.
