pcl, mcl, & lcl ligaments -exam 3 Flashcards
Which ligament is thicker and stronger than the ACL
PCL
PCL attachment
-runs
attaches centrally and posterior on the tibia plateau
attaches ant. on the medial aspect of the intercondylar fossa
runs sup. and ant.
PCL primary restraint:
excessive post. glide and IR
The PCL is the MOST injured knee ligament. T or F
False; LEAST injured
Etiology of PCL injury:
hyper-flexion primary but also hyperextension i.e. car wreck
S&S of PCL injury:
consistent with any ligament injury plus
–ROM limited and P!ful, least limited in ER
—(+) PCL special test
What are the special test(s) for PCL:
Quads active
Posterior Drawer
Post Sag
Reverse pivot shift
Before performing the PCL special tests ensure that the ___________ are relaxed
Quadriceps
Which of the following PCL special test(s) is being described:
In hook lying, pt. slides foot forward; PT guides foot
—________ tibial translation indicates (+) test
Quadriceps active
Anterior
Which of the following PCL special test(s) is being described:
Stabilize pt. foot w/ 90º knee flx in supine HL; glide tibia post
—checking for ______ end feel
Posterior Drawer
abnormal (soft/late empty)
Which of the following PCL special test(s) is being described:
Support heel with hip/knee in 90º/90º flx
–checking for _____ tibia
Post Sag -no force applied
sagging tibia (concavity)
Which of the following PCL special test(s) is being described:
Lay pt. in supine and Erot; apply valgus stress w/EXT
Reverse Pivot Shift
PT Rx for PCL: primary focus
emphasizes on limiting post. tibia gliding
Flat, broad ligament w/ two bands:
MCL or TCL
MCL attachment to: (3)
–runs from
