2024年10月21日 · Knee dislocations are high energy traumatic injuries characterized by a high rate of neurovascular injury. Diagnosis is made clinically with careful assessment of limb neurovascular status. Radiographs should be obtained to document reduction.

2024年6月19日 · Five types of knee dislocation have been described, with respect to tibial displacement compared to the femur 1,2,4: anterior (40%) due to hyperextension injury; usually involves a tear of PCL; an arterial injury is generally an intimal tear due to traction; posterior (~33%) due to axial load to the flexed knee (dashboard injury)

2024年2月27日 · Anterior dislocation: this is due to a hyperextension injury. This is the most common knee dislocation pattern and accounts for 30% to 50% of dislocation injuries. Anterior dislocations have the highest rate of peroneal nerve injury and usually involve a PCL injury.

A lateral dislocation of the knee. They may be divided into five types: anterior, posterior, lateral, medial, and rotatory. [4] This classification is based on the movement of the tibia with respect to the femur. [11] Anterior dislocations, followed by posterior, are the most common. [2]

2013年8月23日 · On the basis of this system, Green and Allen found anterior dislocations to be the most common, representing 40% of the 245 knee dislocations in their study (Fig. 2A). Posterior dislocations represented 33%, lateral 18%, medial 4%, and rotatory 5%.

Anatomy of anterolateral aspect of right knee. The lateral view of the left knee showed a posterior knee dislocation. ↑ Tintinalli, J. E., Stapczynski, J. S., Ma, O. J., Yealy, D. M., Meckler, G. D., & Cline, D. (2016). Injuries to Bones and Joints In Tintinalli's emergency medicine: A comprehensive study guide (Eighth edition.) (pp1863-1864).

categories of dislocation: anterior, posterior, lateral, medial, and rotatory [20]. On the basis of this system, Green and Allen [22] found anterior dislocations to be the most common, representing 40% of the 245 knee dislocations in their study (Fig. 2A). Posterior dislocations represented 33%, lateral 18%, medial 4%, and rotato-ry 5%.

2023年7月5日 · Fractures often accompany a knee dislocation. The knee most commonly dislocates anteriorly or posteriorly, where the tibia is shoved forward or back compared to the femur. This can tear the popliteal artery that runs behind …

Anterior knee dislocations involve the thigh bone (femur) shifting forward relative to the shin bone (tibia). This type of dislocation often results from high-impact trauma, sports injuries, or accidents and can lead to severe pain, instability, and associated injuries.

dislocations were described: anterior, posterior, medial, lateral, and rotatory. Cadaver studies have shown that an anterior dislocation is caused by a hyperextension mechanism that causes a sequential failure of the posterior capsule, posterior cruciate ligament (PCL), and sometimes the anterior cruciate ligament (ACL).15 Both the ACL and PCL ...
