In a prospective seven-year study, we treated 32 patients with partial ruptures of the anterior cruciate ligament (ACL) verified by arthroscopy. Twelve knees (38%) progressed to complete ACL deficiency with positive pivot shift tests and increased anteroposterior translation on tests with the KT-1000 arthrometer. Patients with partial ACL tears frequently had limitation for strenuous sports, while those developing ACL deficiency had additional functional limitations involving recreational activities. Three factors were statistically significant in predicting which partial tears would develop complete ACL deficiency: the amount of ligament tearing--one-fourth tears infrequently progressed, one-half tears progressed in 50% and three-fourth tears in 86%; a subtle increase in initial anterior translation; and the occurrence of a subsequent re-injury with giving-way.
在一项为期七年的前瞻性研究中，我们对32例经关节镜检查证实为前交叉韧带（ACL）部分断裂的患者进行了治疗。12个膝关节（38%）发展为完全ACL缺失，轴移试验呈阳性，使用KT-1000关节测量仪检查时前后移位增加。ACL部分撕裂的患者在剧烈运动时经常受限，而发展为ACL缺失的患者在娱乐活动方面还有额外的功能限制。在预测哪些部分撕裂会发展为完全ACL缺失方面，有三个因素具有统计学意义：韧带撕裂的程度——四分之一撕裂很少进展，二分之一撕裂有50%进展，四分之三撕裂有86%进展；初始前向移位的轻微增加；以及随后出现打软腿的再次损伤。
