Abstract

PURPOSE
To evaluate the MR findings of knee injuries in skiing and to explain the mechanism of injury with MR findings.
MATERIALS AND METHODS
We reviewed MR findings of 18 patients with history of knee injuries in skiing. The MR images were evaluated retrospectively to identify the ligament injuries, bone lesions and meniscal injuries.
RESULTS
Ligament injuries were seen in 16 patients, bone contusions in 16 patients, meniscal lesions in two patients. The most common group of injury was anterior cruciate ligament (ACL) and roedial collateral ligament (MCL) injuries with bone contusion on posterior lip of the lateral tibial plateau (LTP). The second common group of injury was isolated ACL injury with bone contusions on the lateral fernoral condyle (LFC) and posterior lip of the LTP. We considered that the mechanism of injury of the former group may be correlated with the valgus torque with secondary anterior displacement of the tibia and the latter group may be correlated with the pivot shift phenomenon.
CONCLUSION
MR may play an important role in the diagnosis of knee injuries in skiing and its findings may explain the mechanism of injury.
