Three groups were compared: Group I, bilateral ACL tears; Group II, unilateral tears; and Group III, normal knees. Notch dimensions were computer-gen erated from CT scans. All patients were examined for ligamentous laxity. Statistically significant differences were found between normal and ACL-injured knees in regard to opening notch angle, ratio of notch width at two-thirds of the notch length to condylar width, and ratio of maximum notch width to condylar width, sug gesting a significant association between anterior outlet stenosis and unilateral and bilateral ACL tears. The shapes of the notches were determined from tracings of the distal CT scan. Shapes ranged from inverted U to cresting wave. Narrow notches tended to be wave- shaped, but more study is needed in this area. Notch- plasty is recommended for those with documented stenosis. The ratio of maximum notch width at two- thirds of the notch height to maximum condyle width should not be much less than 0.2, and the opening notch angle should be at least 50\u00b0.<\/jats:p>","DOI":"10.1177\/036354658701500605","type":"journal-article","created":{"date-parts":[[2007,6,21]],"date-time":"2007-06-21T20:46:52Z","timestamp":1182458812000},"page":"547-552","source":"Crossref","is-referenced-by-count":197,"title":["Analysis of the intercondylar notch by computed tomography"],"prefix":"10.1177","volume":"15","author":[{"given":"Allen F.","family":"Anderson","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery and Rehabilitation, St. Thomas Hospital, Nashville, Tennessee"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
