To evaluate the diagnostic performance and accuracy of three common physical examination tests in identifying isolated chronic acromioclavicular joint lesions.
Conducted a retrospective case-control study of 35 patients who underwent distal clavicle excision for isolated acromioclavicular joint lesions between 1994 and 2002.
Evaluated sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall accuracy across the cross body adduction stress test, acromioclavicular resisted extension test, and active compression test.
The cross body adduction stress test achieved the highest sensitivity (77%), followed by the resisted extension test (72%) and active compression test (41%).
The active compression test showed the highest specificity (95%) and overall accuracy (92%), followed in accuracy by the resisted extension test (84%) and cross arm adduction test (79%).
All physical tests demonstrated negative predictive values exceeding 94% with positive predictive values below 30%, whereas combining test maneuvers improved diagnostic value.
