What is an articular disc for?

What is an articular disc for?

TMJ Movement: The articular disc or meniscus is a biconcave structure that is positioned above the condyle of the mandible and the glenoid fossa of the temporal bone. The disc allows for a smooth or gliding movement of the condyle in the normal tmj. If the meniscus or disc is abnormally positioned or deformed, it can be a major source for pain and TMJ pathology. ...Read more

This condition might be causing you problems, but arthroscopic surgery is not truly indicated unless your knee is locking. Good luck! ...Read more

MRI knee: sounds suspicious for a type III signal which usually indicates a tear of the meniscus. That said, even if there is a 'tear' surgery is not necessarily needed. check with your local orthopedist. ...Read more
