Internal derangement of the knee - Acute Meniscal Tear Factor
Definition
Acute meniscal tears are injuries involving tearing of the lateral or medial meniscus in the knee joint.
Signs and symptoms
The signs of an acute meniscal tear would include sudden onset of pain and tenderness in the knee (within 24 hours of the injury), and could include swelling, locking, or loss of functional ability.
Establishing onset
A history of an acute meniscal tear may be documented in the evidence. However, the person may not have sought medical attention for such an injury. In addition, all relevant medical records may not be available, therefore, a statement that an acute meniscal tear occurred at a particular time will generally be accepted, unless there is contradictory evidence. Seek medical advice if the onset of the acute meniscal tear is unclear.

Clinical onset and operational service [41980]
41984 the acute meniscal tear to side and site of the body is causally related to operational service.
Clinical onset and eligible service [41981]
41985 the acute meniscal tear to side and site of the body is causally related to eligible service.
Clinical worsening and operational service [41982]
41984 the acute meniscal tear to side and site of the body is causally related to operational service.
41986 the clinical onset of the internal derangement of the knee occurred prior to that part of operational service to which the acute meniscal tear is causally related.
Clinical worsening and eligible service [41983]
41985 the acute meniscal tear to side and site of the body is causally related to eligible service.
41987 the clinical onset of the internal derangement of the knee occurred prior to that part of eligible service to which the acute meniscal tear is causally related.
