ACL, PCL tear,
fracture,
knee dislocation,
patellar dislocation
lateral blow to the knee might indicate
MCL tear
medial blow to the knee might indicate
LCL tear
knee “gave out” or buckled might indicate
ACL tear (years of wear and tear) patellar dislocation
fall onto a flexed knee might indicate
PCL tear (tibia gets driven backwards) -rare in isolation
what would be a positive patellofemoral grinding test?

on the inside of the foot medially
protects against eversion
fans out from inferior surface of medial malleolus to the talus and proximal tarsal bones

arthritis
ligamentous injury
infection
when would a ligament not illicit tenderness?
no pathology
if it’s completely torn
