ABO blood groups are associated with various diseases.
A relationship
between Achilles tendon ruptures and blood type O has been reported, although its
pathogenesis was not clear. To the best of our knowledge, there is no published
study describing the relationship between blood type and rotator cuff tendon
tears. OBJECTIVE: To determine whether patients with rotator cuff tear had a
greater prevalence of blood type O than those without rotator cuff tear. DESIGN:
A cross-sectional study. SETTING: Research hospital outpatient evaluation.
PARTICIPANTS: A total of 316 subjects with shoulder pain were included and
divided into "tear" and "no-tear" groups according to ultrasonographic
examination. MAIN OUTCOME MEASURES: ABO blood group, gender, dominant arm,
smoking history, trauma history, and age were compared between the 2 groups and
the odds ratios of these factors were evaluated by logistic regression. RESULTS:
The tear group (38.6%) had more instances of blood type O than the healthy
population (27.2%; P = .002). The adjusted odds ratio for rotator cuff tear for
blood type O to non-O was 2.38 (95% confidence interval 1.28-4.42). The odds
ratios for rotator cuff tears for smoking, major trauma history, minor trauma
history, and age were 2.08, 3.11, 2.29, and 1.06, respectively. CONCLUSION:
Patients with rotator cuff tears were more likely to have blood type O. The odds
ratios of factors for rotator cuff tears were high in the following order: major
trauma history, blood type O, minor trauma history, and age.
