what is meaning knee sprain
Other names: Ligament tear, knee strain. A knee sprain simply means that one of the knee ligaments has been overstretched and that some or all of the fibres have been damaged. This usually occurs when there is a force through the knee eg a tackle in sport or sudden twisting of the knee eg when falling awkardly.ere we will look at the most common causes of a knee sprain and which ligament tends to be affected: 1) ACL Sprain: Sudden twisting or hyperextension (the knee bending back too far). 2) PCL Sprain: Force through a bent knee e.g. a fall onto a bent knee, car accident where the knee hits the dashboard.
