The ACL evaluation format is a modification and extension of Marshall's approach to evaluation of ligamentous injuries of the knee, whereby functional and clinical improvement can be analyzed independently as well as cumulatively. There are three major parts entered on separate forms: history and surgery (Form 1); initial evaluation and follow-up (Form 2); and complications (Form 3). Form 1 has five sections: patient information (demography); history of injury; previous surgery; surgery performed; and postoperative course. Form 2 has six sections. These are the Lysholm knee function scoring scale, Tegner activity level rating scale, physical findings, complications, supplementary data, and Tegner activity level definitions. Form 2 records the preoperative and follow-up assessments for up to a five-year follow-up period. Form 2 can be used independently of the other forms. Form 3 elaborates in a detailed manner a complication occurrence. The format provides the evaluator with an easy to use, “computer/user friendly,” method for the comprehensive assessment of artificial or autologous anterior cruciate reconstruction of the knee. The authors advocate the use of the ACL format as an international standard for data storage to facilitate comparison of results with accuracy and uniformity among investigation centers.
