Results
328 knee MR examinations identified only proximal (19%),
middle portion (6%) and distal (22%) mucoid impairment; diffuse involvement was recorded in 53%.
In all patients both bundles were involved.
The one year follow−up examinations didn’t show any change in 90% of ligament; in the remaning 10% with partial mucoid involvement was reported a progression from distal,
middle or proximal to diffuse involvement.
The two and seven years follow-up exams detected a complete and diffuse mucoid impairment in all cruciate anterior ligaments with decreased trasversal size in 66% of ligaments in the seven year follow-up No patient developed a partial/complete tear and showed knee clinical instability during the period covered.
figures 1.2. T1-weighted axial and sagittal images demonstrate an ill-defined,
enlarged ligament with increased signal intensity in the proximal portion.
figures 3.4. T1-weighted axial and sagittal images of the same patient five years later demonstrate a diffuse ill-defined,
enlarged ligament with increased signal intensity with the normal orientation.
