- See:
Rim Fractures:
- Ligaments:
- 60% of plateau frx will have ligamentous instability;
-
MCL accounted for 55%, LCL injuries for 22%,
& combined cruciate & collateral injuries for 23% of lesions.
- these may have poor prognosis;
- Exam:
- w/ isolated plateau frx, significant widening of the opposite joint line,
should not occur;
- Radiographs:
- look for widening of joint space (indicates collat. lig disruption);
- Treatment:
- according to Rasmussen, surgery is indicated for tibial plateau frx, along w/
varus or valgus instability of 10 deg or more w/ knee flexed 20 deg;
