The Tests of Collateral Ligaments
What other injuries are ruled out?
- Pain in the area of a collateral ligament tears can also occur in the meniscus or cartilage neighbors.
- The feeling of instability may also occur in lesions of cruciate ligaments, or patella cartilage.
- If the joint opens when the doctor kept slightly flexed knee, as well as the remains stretched, it is likely that the ligaments are also torn.
