How do you evaluate and treat lateral collateral ligament pain?

LCL evaluation knee: The lcl in the knee is evaluated at o degrees (full extension) and at 30 degrees of flexion with varus stress applied. Degree of opening is assessed by estimating in mm and comparing to opposite side; lcl sprains or tears are measured as grade i, ii, or iii. The posterolateral corner (e.g. Arcuate complex) should be assessed as well as the cruciate and medial collateral ligaments. Mri is also used.
