Purpose: The purpose of this research study was to determine the sensitivity, specificity, and efficiency of the anterior draw test (AD), Lachman test, and the pivot shift test to detect laxity in the anterior cruciate ligament (ACL). Experimental Method: A total of twenty-eight male patients were selected for this study, and had to meet the following criteria. Each patient must have had ACL surgery, where three or more weeks had passed since the surgery, and the patellar tendon bone graph was used for each ACL surgery. Furthermore, each patient was examined for laxity in the ligament, and an MRI of the knee was taken too. Each of the patient’s knee was examined for ligament laxity in an outpatient setting, and under anesthesia. The sensitivity and specificity of each test would range from 2 to…show more content…
Lastly, the pivot shift test could distinguish 21 of the 28 patients had an ACL injury, with a sensitivity of 75, specificity of 100%, and efficiency of 75%. Under anesthesia the pivot test recognized all 28 patients with an ACL injury, giving it a 100% efficiency, sensitivity of 100, and specificity of 100%. The Lachman and AD test both identified 26 of the 28 with an ACL injury, giving them both the efficiency of 92.9%, a sensitivity of 92.9 and specificity of 100%. Conclusion: For outpatient, the AD and Lachman test are great for recognizing an ACL injury, and laxity in the ligament. The pivot shift test is outstanding in recognizing ligament laxity, and ACL injury in those under anesthesia. All three tests can be used in an outpatient setting with good results, but some are more consistent that others depending on the
