Posterior Cruciate Ligament Injury Associated with Patellar Fracture
|
|
|
|
|
Abstract
|
|
|
Patellar fractures result from direct and/or indirect forces. The majority of the patellar fractures result from direct injuries and a fall on the knee or a direct blow sustained in the vehicular trauma is one of the common causes. Patellar
fractures
from indirect forces occur when the intrinsic strength of the patella is exceeded by the pull of the musculotendinous and ligamentous units attaching to it and typically occurs in the act of stumbling or partially falling.
Posterior cruciate ligament disruption is generally caused by a posteriorly directed force on the proximal tibia, and hyperextension with abduction or external rotation movements have been also described in the production of posterior cruciate
ligament
injuries. Posterior cruciate ligament injuries are apt to be negelected frequently, and ipsilateral femoral shaft fracture or posterior dislocation of the hip also may be seen with direct injuries to the patella, but patellar fractures are rarely
associated with posterior cruciate ligament injuries.
So we are reporting four cases of the posterior cruciate ligament injuries as one of the combined entity, which had been neglected and associated with the patellar fracture after a review of the literatures.
