The function of Ligaments is to give stability to the joint, while also allowing for joint mobility.

4) LCL - Lateral collateral ligament

All ligaments need to be in good strength to allow for painless knee function.


3) how do ligaments tear?

Dr. Pilankar : when the ligaments are stretched beyond their capacity, the ligament can tear. Tears can happen Sports like soccer, basketball , hockey where there is a sudden twisting motion, or an incorrect landing from a jump.


4) what is knee sprain? Is it same as ligament tear?

Dr. Pilankar: sprains are injuries to ligament in which only a few fibres are damaged but the ligament is intact.

In complete ligament tear, the ligament continuity is disrupted.
