INTRODUCTION: @entity130 of the knee ligaments present in various degrees of severity from interstitial sprains to complete ligament tears. The femoral insertion of the anterior cruciate ligament (ACL) is susceptible to post-traumatic ischemic changes secondary to interrupted vascular supply from the tibial insertion. In comparison, the @entity3057 ( @entity3057 ) has more extensive vascularization from the posterior geniculate arteries, which allows better healing of these injuries with @entity17790 . MRI of a scarred @entity130 shows lower than normal signal intensity, which post-traumatic changes in signal intensity are well described in the literature. In my personal experience with more than 5500 MR examinations of the knee, @entity3057 traumatic injuries secondary to motor vehicle accidents or @entity2587 are a frequent finding. Many of these @entity1 are completely asymptomatic for articular instability. MATERIAL AND METHODS: From November, 1994, to July, 1997, a direct MR follow-up was proposed to @entity1 with @entity3057 traumatic tears. Only the @entity1 examined in our hospital were included in this study because the MR scans were performed using the same unit, matrix, FOV, slice thickness and sequences. Twenty @entity1 had acute traumatic injuries of the @entity3057 . Four were not examined because of an additional traumatic episode and four were not included because they were operated on. Ten @entity1 were thus enrolled: three @entity1 and seven @entity1 whose age ranged 23 to 41 years (mean: 35.7). MR follow-up ranged 9 to 36 months (average: 14.2). RESULTS: At the first MR examination, @entity3057 tears were classified as follows: Gross class II (1 @entity1 ) and Gross class III (9 @entity1 ). Follow-up MRI showed no @entity3057 in 2 @entity1 (similar to @entity63 in complete ACL tears), focal interligament changes within a continuous @entity3057 in 2 @entity1 and normal @entity3057 in 6 @entity1 . The @entity130 was caused by a motor vehicle accident with the knee flexed in 8 @entity1 and during hyperflexion in sports activity (skiing or soccer) in 2 @entity1 . Five @entity1 presented with knee instability and subjective complaints, such as @entity158 and difficulty in climbing stairs, walking, running, or performing sports activity. Follow-up MRI showed natural repair of the @entity130 in 5 @entity1 , with absolutely no knee instability. CONCLUSION: Even though the number of @entity1 in this study is limited, follow-up MRI confirms the possibility of scar tissue repair in @entity3057 post-traumatic injuries, supporting primary conservative treatment.
