What is a medial meniscus displacement? what can be done to fix the displacement?

Out of place: My guess: displacement means it is pushed/displaced from its original location from some type of injury/trauma i.E a tear. If it is slight and not causing pain, you may not nee to do anything. If it is causing some discomort, motrin/aleve and physical therapy/knee rehab may help. If still persistent, you may need to see an ortho for a possible surgical correction .. Consult your doc... Good luck.

Out of place: It just means the the tear is in a position that is not normal or anatomic. It does not predict whether it could be repaired or not at the time of an arthroscopic surgery.
