When diagnosing the internal derangement of the knee, the doctor may want to know the medical history of a person. There usually several exams that help to rule out some of the doubts that one may have. Some of the tests that may be carried out to diagnose this condition include range of motion, valgus test, palpation, McMurray's test, Thessaly's test, posterior drawer and varus test.

An internal derangement of the knee may involve an injury to the bone, muscle, ligament, tendon or meniscus. Rehabilitation may be required to help in treating the injury and this will depend on the nature of the injury, functional plans of a person and type of treatment, as stated by MDGuidelines.
