We used thick\u2010sliced T1\u2010weighted sagittal MRI to quantify ATS at full extension. To measure ATS, MRIs were loaded into a personal computer, and the contour of the unaffected knee was compared with the affected knee using Photoshop software (Adobe, San Jose, CA). Anterior instability was measured using a KT\u20101000 arthrometer (MedMetric, Inc, San Diego, CA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The extent of ATS in 96 ACL\u2010deficient knees was 2.1 \u00b1 1.3 mm (mean \u00b1 SD) and the range was 0 to 4.6 mm.
