Pivoting sports involvement at the time of injury, abnormal lateral posterior-inferior tibial slope, anterolateral capsular ligament disruptions and combined lateral meniscal lesions were predictors of grade 3 pivot shift for acute ACL injuries, according to results.
In a retrospective review of patients who underwent primary ACL reconstruction between 2009 and 2015 after an acute ACL injury, researchers identified 30 patients with grade 3 pivot shift as the study group and randomly chose 30 patients with grade 1 and 30 patients with grade 2 pivot shift as two control groups. Patients performed pivot-shift tests under anesthesia, and the study group was compared with the two control groups.
Compared with the control groups, results showed pivoting sports involvement at the time of injury, abnormal degree of lateral posterior-inferior tibial slope, anterolateral capsular ligament disruptions and combined lateral meniscal lesions had a significantly higher prevalence in the study group and were independent risk factors associated with grade 3 pivot shift after acute ACL injuries. Researchers found the study group had a significantly higher prevalence of combined severe lateral meniscal lesions compared with both control groups. Patients with two or more risk factors had a prevalence of 90% in the study group vs. 16% in the control group with grade 1 pivot shift and 40% in the control group with grade 2 pivot shift, according to results. – by Casey Tingle
