1               Name

This is the Statement of Principles concerning chondromalacia patella (Balance of Probabilities) (No. 2 of 2019).

2               Commencement

              This instrument commences on 28 January 2019.

3               Authority

This instrument is made under subsection 196B(3) of the Veterans' Entitlements Act 1986.

4               Repeal

The Statement of Principles concerning chondromalacia patella No. 80 of 2010 (Federal Register of Legislation No. F2010L02319) made under subsection 196B(3) of the VEA is repealed.

5               Application

This instrument applies to a claim to which section 120B of the VEA or section 339 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 chondromalacia patella and death from chondromalacia patella.

Meaning of chondromalacia patella

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

(a)          means softening, fibrillation or erosion of the articular cartilage of the patella associated with recurrent or chronic patellofemoral pain; and

(b)          excludes osteoarthritis of the patellofemoral joint.

(3)          While chondromalacia patella attracts ICD‑10‑AM code M22.4, in applying this Statement of Principles the meaning of chondromalacia patella 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 chondromalacia patella

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

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

8               Basis for determining the factors

On the sound medical‑scientific evidence available, the Repatriation Medical Authority is of the view that it is more probable than not that chondromalacia patella and death from chondromalacia patella can be related to relevant service rendered by veterans or members of the Forces under the VEA, or members under the MRCA.

Note: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary.

9               Factors that must exist

At least one of the following factors must exist before it can be said that, on the balance of probabilities, chondromalacia patella or death from chondromalacia patella is connected with the circumstances of a person's relevant service:

(1)          having direct trauma to the patella of the affected knee within the three months before the clinical onset of chondromalacia patella;

Note: direct trauma to the patella is defined in the Schedule 1 - Dictionary.

(2)          having patellar dislocation of the affected knee within the three months before the clinical onset of chondromalacia patella;

(3)          having an injury to the affected knee resulting in acute meniscal or ligamentous tear of the knee or permanent ligamentous instability, within the six months before the clinical onset of chondromalacia patella;

(4)          having acquired abnormal tracking of the patella of the affected knee for at least the three months before the clinical onset of chondromalacia patella;

Note: abnormal tracking of the patella is defined in the Schedule 1 - Dictionary.

(5)          running or jogging an average of at least 60 kilometres per week for at least the four weeks before the clinical onset of chondromalacia patella;

(6)          undertaking weight bearing exercise involving forceful loading of the affected patellofemoral joint, at a minimum intensity of five METs for at least six hours per week, for at least the four weeks before the clinical onset of chondromalacia patella;

Note: MET is defined in the Schedule 1 - Dictionary.             

(7)          increasing the frequency, duration or intensity of weight bearing activity involving the affected knee by at least 100 percent, to a minimum intensity of five METs for at least four hours per day, for at least the seven days before the clinical onset of chondromalacia patella;

Note: MET is defined in the Schedule 1 - Dictionary.             

(8)          having direct trauma to the patella of the affected knee within the three months before the clinical worsening of chondromalacia patella;

Note: direct trauma to the patella is defined in the Schedule 1 - Dictionary.

(9)          having patellar dislocation of the affected knee within the three months before the clinical worsening of chondromalacia patella;

(10)      having an injury to the affected knee resulting in acute meniscal or ligamentous tear of the knee or permanent ligamentous instability, within the six months before the clinical worsening of chondromalacia patella;

(11)      having acquired abnormal tracking of the patella of the affected knee for at least the three months before the clinical worsening of chondromalacia patella;

Note: abnormal tracking of the patella is defined in the Schedule 1 - Dictionary.

(12)      running or jogging an average of at least 60 kilometres per week for at least the four weeks before the clinical worsening of chondromalacia patella;

(13)      undertaking weight bearing exercise involving forceful loading of the affected patellofemoral joint, at a minimum intensity of five METs for at least six hours per week, for at least the four weeks before the clinical worsening of chondromalacia patella;

Note: MET is defined in the Schedule 1 - Dictionary.             

(14)      increasing the frequency, duration or intensity of weight bearing activity involving the affected knee by at least 100 percent, to a minimum intensity of five METs for at least four hours per day, for at least the seven days before the clinical worsening of chondromalacia patella;

Note: MET is defined in the Schedule 1 - Dictionary.             

(15)      inability to obtain appropriate clinical management for chondromalacia patella.

10           Relationship to service

(1)          The existence in a person of any factor referred to in section 9, must be related to the relevant service rendered by the person.

(2)          The factors set out in subsections 9(8) to 9(15) apply only to material contribution to, or aggravation of, chondromalacia patella where the person's chondromalacia patella was suffered or contracted before or during (but did not arise out of) the person's relevant service.

11           Factors referring to an injury or disease covered by another Statement of Principles

In this Statement of Principles:

(1)          if a factor referred to in section 9 applies in relation to a person; and

(2)          that factor refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(3) of the VEA;

then the factors in that Statement of Principles apply in accordance with the terms of that Statement of Principles as in force from time to time.
