Grading System for Ligamentous Laxity

Question 1

Damage: Slight stretching of the ligament with little, if any, tearing of the fibers. Pain is present, but the degree of laxity roughly compares with that of the opposite extremity.

Answer 1

Grade 1 - Firm (normal) end-feel

Question 2

Damage: Partial tearing of the fibers. There is increased play of the joint surfaces upon one another or the joint line “opens up” significantly when compared with the opposite side.

Answer 2

Grade 2 - Soft end-feel

Question 3

Complete tearing of the ligament. The motion is excessive and becomes restricted by secondary restraints, such as tendons.

Answer 3

Grade 3 - Empty end-feel
