- Abstract
PURPOSE: The purpose of this study was to evaluate the scar pattern of ACL due to reconstruction and to compare anterior laxity with each scar type. METHODS: A total of 77 patients who had undergone ACL reconstruction were collected. They consisted of 47 males and 30 females, and the average age was 31.4 years. We investigated the course from injury to operation, the experience of giving way, and the present of meniscus tearing. Anterior laxity was also measured for anterior-to-posterior drawer distance compared to the normal opposite knee using KT-2000 preoperatively. Arthroscopic evaluation of the scar pattern was evaluated using a modified Crain's classification: partial rupture (I), scarring to the roof of the notch (II), scarring to the lateral wall more anterior and distal (III), scarring to the posterior cruciate ligament (IV), and resorption (IV). RESULTS: There were 15 patients in group I, 9 group II, 8 group III, 12 in group IV, and 25 in group V. The mean value of KT-2000 was 2.82 mm in group I, 3.05 mm in group II, 4.56 mm in group III, 4.13 mm in group IV, and 5.59 mm in group V. The value of KT-2000 in-group V was significantly greater than in groups I and II (P<0.01). The course from injury to operation, experience of giving way and presence of meniscus tearing were not correlated to the scar pattern. [ABSTRACT FROM AUTHOR]
