Results
Based on radiological measurements and analysis,
the following classification has been proposed:
grade 0 – no damage,
the bone’s shape remains intact;
grade I – edema resulting from the contusion of the bone,
no changes in the bone shape;
grade II – slight compression of the bone with the lateral meniscus still being fully supported.
grade III - is recorded in cases where bone degradation allows for only about 50% of the support of the meniscus,
whereas grade IV means the meniscus has less than 50% of support.
Out of preliminarily selected 336 cases of acute complete ACL rupture,
the total of 220 patients was diagnosed with accompanying bone bruising which equals 65,5% of all cases.
Further analysis of subjects' scans revealed:
- 52 cases of grade I (23,6%),
- 116 cases of grade II (52,7%).
- In 39 instances the meniscus was not adequately supported indicating grade III (17,7%);
- and in the case of 13 patients the degradation of the area supporting the lateral meniscus extended to the point allowing us to label them as grade IV (6%).
