The Active Compression Test: A New and Effective Test for Diagnosing Labral Tears and Acromioclavicular Joint Abnormality.
Am J Sports Med 26: 610-613, 1998.
Superior labral tears are difficult to diagnose. A new test for detection of labral abnormality and acromioclavicular joint abnormality is presented which is both specific and sensitive.
Technique : The physician stands behind the patient, who flexes the affected arm forward at 90o with the elbow at full extension, adducts the arm 10-15 medial to the sagittal plane and internally rotates it till the thumb points downward. The physician applies downward pressure on the arm. The maneuver is repeated with the palm fully supinated. The test is positive if there is pain with the first maneuver that is reduced or eliminated with the second maneuver. Pain on the shoulder in the acromioclavicular joint is indicative or acromioclavicular joint abnormality, whereas pain or painful clicking is diagnosed as labral abnormality.
Results : Of 56 patients who had positive active compression tests, 53 were found to have labral tears. The remaining 3 patients had a reverse Hills-Sach’s lesion, a hypermobile biceps tendon and multidirectional laxity and biceps tendinitis and anterior instability without a discrete labral tear. The specificity was 100% and the specificity 98.5%, the positive predictive value was 94.5% and the negative predictive value was 100%.

Arthroscopic Repair of Full-Thickness Tears of the Rotator Cuff
J Bone Joint Surg Am 80-A: 832-840, 1998.
This is a study of 73 patients (mean age 60.7 years) who underwent arthroscopic repair of full thickness rotator cuff tears. 69 patients had an anatomical repair and 4 were repaired a mean 3mm medial to the insertion of the tendon. The scope could also detect that 63 glenohumeral joints were normal and 10 had an intra-articular lesion. 90% rated the result as good to excellent.
This technique should be used only by experienced surgeons. The open operation is relatively easy, but the advantage of arthroscopy includes smaller incision, access to the glenohumeral joints and treatment of intra-articular lesions, no need to detach the deltoid and less soft tissue desection.
