The pivot shift is a common injury mechanism during an anterior cruciate ligament injury in which the tibia rotates anterolaterally with a combined valgus force. This mechanism can lead to bone bruising and even impaction fractures of the lateral femoral condyle. High-grade pivot-shift cases can also lead to pinching of the lateral meniscus, causing tearing. In cases with a sufficient valgus force, combined injuries, including the medial collateral ligament, can also occur. This video technique describes the reconstruction of the anterior cruciate ligament and medial collateral ligament, lateral meniscus radial tear repair, and reduction of a lateral femoral condyle impaction fracture caused by a high-grade pivot-shift injury.
轴移是前交叉韧带损伤时常见的损伤机制,在此过程中胫骨在合并外翻力的作用下向前外侧旋转。这种机制可导致骨挫伤,甚至外侧股骨髁的嵌插骨折。严重的轴移病例还可导致外侧半月板受压,引起撕裂。在有足够外翻力的情况下,还可能发生包括内侧副韧带在内的合并损伤。本视频技术描述了前交叉韧带和内侧副韧带的重建、外侧半月板放射状撕裂修复以及严重轴移损伤所致外侧股骨髁嵌插骨折的复位。
