Internal derangement of the knee

Osteoarthritis - Internal derangement of the knee Factor

This contention only applies to osteoarthritis of a knee joint.

General information

Internal derangement of the knee is a long term condition and should not be confused with acute sprain or acute strains which are of short duration. Internal derangement of the knee is a diagnostic term used to encompass chronic meniscal and ligament injuries, alone or in combination. Diagnosis is usually made by arthroscopy.Manifestations include pain, locking and giving way of the knee joint.

Establishing onset

If the person had internal derangement of the knee he or she would have needed significant medical attention at some time – usually at the time of the original injury. Such medical treatment would normally be recorded in doctors' notes, hospital records or service medical records. However, if these records have been destroyed or can no longer be obtained and there is a reliable history of internal derangement of the knee at a particular time, this generally will be accepted, unless there is contradictory evidence. Obtain medical advice if it is unclear whether the claimed symptoms and treatment at that time can be attributed to internal derangement of the knee rather than to some other condition.

Clinical onset and operational service [25612]

25616  the internal derangement of side and site of the body is causally related to operational service.

Clinical onset and eligible service [25613]

25617  the internal derangement of side and site of the body is causally related to eligible service.

Clinical worsening and operational service [25614]

25616  the internal derangement of side and site of the body is causally related to operational service.

25618 the clinical onset of the condition under consideration occurred prior to that part of operational service to which internal derangement of side and site of the body is causally related.

Clinical worsening and eligible service [25615]

25617  the internal derangement of side and site of the body is causally related to eligible service.

25619 the clinical onset of the condition under consideration occurred prior to that part of eligible service to which internal derangement of side and site of the body is causally related.
