1               Name

This is the Statement of Principles concerning osteoarthritis (Reasonable Hypothesis) (No. 61 of 2017).

3               Authority

This instrument is made under subsection 196B(2) of the Veterans' Entitlements Act 1986.

5               Application

This instrument applies to a claim to which section 120A of the VEA or section 338 of the Military Rehabilitation and Compensation Act 2004 applies.

6               Definitions

The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument.

7               Kind of injury, disease or death to which this Statement of Principles relates

(1)          This Statement of Principles is about osteoarthritis and death from osteoarthritis.

Meaning of osteoarthritis

(2)          For the purposes of this Statement of Principles, osteoarthritis:

(a)          means a degenerative joint disorder with:

(i)            clinical manifestations of pain, impaired function and stiffness; and

(ii)         osteophytes or loss of articular cartilage; and

(b)          excludes acute articular cartilage tear and osteochondritis dissecans.

Note 1: Other commonly associated features are sclerosis of the underlying bone, inflammation of the synovium and, for osteoarthritis in the knee, degenerative tears of the menisci and, for osteoarthritis in the hip or shoulder, degenerative tears of the labrum.

Note 2: The osteophytes or loss of articular cartilage may be assessed by radiological, other imaging or arthroscopic investigations.

(3)          While osteoarthritis attracts ICD‑10‑AM code M15, M16, M17, M18 or M19, in applying this Statement of Principles the meaning of osteoarthritis is that given in subsection (2).

(4)          For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4.

Death from osteoarthritis

(5)          For the purposes of this Statement of Principles, osteoarthritis, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's osteoarthritis.

Note: terminal event is defined in the Schedule 1 – Dictionary.

8               Basis for determining the factors

The Repatriation Medical Authority is of the view that there is sound medical‑scientific evidence that indicates that osteoarthritis and death from osteoarthritis can be related to relevant service rendered by veterans, members of Peacekeeping Forces, or members of the Forces under the VEA, or members under the MRCA.

Note: relevant service is defined in the Schedule 1 – Dictionary.

9               Factors that must exist
