Just curious of anyone knows this...We always hear of PCL, MCL, and ACL sprains/tears.
Why is it there are hardly ever any LCL problems? Is it harder to injure or something?
I suppose it may have something to do with the fact that it's attached to the femur and fibula on the inside of the knees, thus giving it a buffer from being stretched too far (If I understand it correctly, more extension damage to all other parts of the joint would occur if the LCL is damaged.) The PCL and ACL just cross each other--attached to no bone in front or behind them--and, thus, have no "brace" or foundation. I think they're just more exposed to isolated damage.
No.Medial = inside of knee.
Lateral = outside of knee.
So to injure the lateral collateral you would have to suffer a blow to the inside (medial) part of the knee forcing the knee in varus which would stretch the lateral ligament. Football players usually get hit from the lateral, front or back but rarely from the inside of the knee.
And the ACL and PCL do indeed attach to bones. Actually by definition all ligaments do (tendons do not --- they connect muscle to bone). The ACL and PCL both connect the femur to tibia. The difference is that one goes front to back (ACL) and one goes back to front (PCL).
