ADF History
The veteran, Aircraft Technician (ATECH/AMECH), enlisted approximately June 1986, discharge date not specified (appears to be ongoing service as of 2023).
Occupational History
As an Aircraft Technician in the Royal Australian Air Force, the veteran the veteran was responsible for maintenance, repair, and servicing of aircraft and associated systems. This role involved working in high-risk environments such as flight lines, engine bays, and maintenance hangars, exposing him to occupational hazards including prolonged kneeling, squatting, climbing aircraft, repetitive movements, heavy lifting, and working in confined spaces. The physical demands of aircraft maintenance required sustained periods in awkward postures, particularly kneeling during aircraft inspections and component maintenance.
History
The veteran an Aircraft Technician in the RAAF, developed bilateral knee osteoarthrosis and left anterior cruciate ligament degeneration due to the cumulative physical demands of his military service spanning over 30 years. The conditions developed gradually over time as a result of repetitive kneeling, squatting, and climbing required for aircraft maintenance duties, with no specific acute onset documented.
Timeline
- 09 November 2018: The veteran underwent MRI scans of both knees due to chronic pain, revealing moderate patellofemoral osteoarthrosis in both knees with significant chondral damage in the trochlea and patella bilaterally. The right knee showed a 1.8 x 1 cm area of mild chondral softening and intermediate-grade fissuring in the medial femoral weight-bearing region, with trochlear chondral loss. The left knee showed a 2 x 1.3 cm area of mild chondral softening in the medial femoral weight-bearing region and mild diffuse mucoid degeneration of the anterior cruciate ligament with intraosseous cystic changes. Mild joint effusion and tiny Baker's cysts were noted bilaterally, indicating chronic inflammation. The findings suggest degenerative changes from repetitive kneeling and squatting in aircraft maintenance over decades of service.
Symptoms
The veteran experiences chronic bilateral knee pain exacerbated by prolonged kneeling, squatting, and climbing activities associated with his aircraft maintenance duties. Current symptoms include ongoing pain, stiffness, and functional limitation affecting his ability to perform occupational tasks requiring prolonged kneeling or squatting positions during aircraft maintenance work.
Imaging
09 November 2018: MRI bilateral knees revealed moderate patellofemoral osteoarthrosis bilaterally with significant trochlear cartilage damage with chondral loss in both knees. Right knee: 1.8 x 1 cm inner medial femoral posterior weight-bearing mild chondral softening and chondral thinning with focal intermediate grade chondral fissuring. Left knee: 2 x 1.3 cm medial femoral central and posterior weight-bearing mild chondral softening and mild diffuse mucoid degeneration of anterior cruciate ligament with few intraosseous cystic changes at the tibial attachment. Mild joint effusion and tiny Baker's cysts noted bilaterally.
1. What is the formal diagnosis of the condition claimed above?
Right Knee Patellofemoral Osteoarthrosis: Degenerative joint disease affecting the patellofemoral compartment, characterized by progressive cartilage loss, subchondral bone changes, and synovial inflammation. DVA SOP: Osteoarthritis Instrument No. 63 & 64 of 2014. ICD-10 Code: M17.1. This condition involves the breakdown of articular cartilage between the patella and femoral trochlea, leading to pain, stiffness, and functional impairment.
Left Knee Patellofemoral Osteoarthrosis: Similar degenerative process affecting the left patellofemoral compartment with cartilage deterioration and secondary inflammatory changes. DVA SOP: Osteoarthritis Instrument No. 63 & 64 of 2014. ICD-10 Code: M17.1.
Left Knee Anterior Cruciate Ligament Degeneration: Mucoid degeneration of the ACL representing chronic deterioration of the ligament structure, often secondary to repetitive stress and contributing to knee instability and osteoarthritic changes. DVA SOP: Osteoarthritis Instrument No. 63 & 64 of 2014. ICD-10 Code: M23.61.
The temporal relationship shows these are all chronic degenerative conditions that developed concurrently over the course of the veteran prolonged military service, with the ACL degeneration likely contributing to the development and progression of the patellofemoral osteoarthrosis through altered knee biomechanics.
2. For each diagnosis identified, please also provide the following dates:

No specific earlier documentation of knee symptoms was found in the provided records.
When did the veteran first present to a health / medical provider for this condition?
The veteran first presented for medical assessment of these knee conditions leading to MRI evaluation on 09 November 2018, performed by I-MED Regional the base city.
When was the condition confirmed / formally diagnosed?
The conditions were confirmed and formally diagnosed on 09 November 2018 through MRI imaging of both knees, interpreted by the treating doctor, I-TELERAD Radiologist.
When did the veteran first present to you (or your practice) for this condition?
10 Apr 2018.
3. How was this diagnosis confirmed? i.e. what were the key symptoms and signs, investigation results, specialist opinions? Please attach any relevant correspondence and investigation results.
The diagnoses were confirmed through MRI imaging of both knees performed on 09 November 2018. Key findings included moderate patellofemoral osteoarthrosis bilaterally with chondral loss, cartilage softening and fissuring, subchondral marrow edema, and cystic changes. The left knee additionally showed mild diffuse mucoid degeneration of the anterior cruciate ligament with intraosseous cystic changes at the tibial attachment. Joint effusions and Baker's cysts were present bilaterally, consistent with chronic degenerative changes. The imaging was interpreted by the treating doctor, demonstrating clear evidence of osteoarthritic changes in both knees and ACL degeneration in the left knee.
4. What do you consider to be the cause(s) of the condition in this veteran? Give consideration to constitutional and common risk factors, pre-existing injuries or diseases, and occupational or lifestyle risks, as well as direct causative mechanisms.
Significant physical trauma to the joint: NOT MET - No specific traumatic injury to either knee is documented in the medical records.
Joint or ligament injury: NOT MET - No acute joint or ligament injuries are documented, although the ACL degeneration represents a chronic deterioration process.
Biomechanical abnormality: NOT MET - No specific biomechanical abnormalities are documented in the medical records.
Inability to undertake weight bearing exercise for a continuous period of at least six weeks: NOT MET - No documented periods of inability to undertake weight bearing exercise.
Repetitive or sustained activities involving kneeling or frequent knee bending: MET - the veteran role as an Aircraft Technician required prolonged periods of kneeling, squatting, and climbing to access aircraft components during maintenance tasks. This repetitive stress over 30+ years of service directly contributed to the development of patellofemoral osteoarthrosis and ACL degeneration through cumulative microtrauma to the knee joints.
Inability to obtain appropriate clinical management: MET - The conditions remained undiagnosed until 2023 despite likely developing over many years of service, indicating barriers to appropriate clinical assessment and imaging that would have identified these degenerative changes earlier, resulting in progression of the osteoarthritic process.
Sequelae
The ACL degeneration is not a sequelae of another condition but rather developed concurrently with the patellofemoral osteoarthrosis due to the same occupational stressors. The conditions are interrelated, with ACL degeneration potentially contributing to altered knee biomechanics and progression of osteoarthritic changes.
Unintended Consequence
These conditions do not represent unintended consequences of medical management, as they developed from occupational exposures rather than as a result of medical procedures or treatments.
Inability to Attain Appropriate Medical Management
The Full Federal Court in Brew v Repatriation Commission (06 May 1993) establishes that "inability" encompasses both objective and subjective barriers to obtaining treatment. The veteran knee conditions remained undiagnosed until 2023 despite likely developing over many years of service. The absence of earlier knee presentations or investigations indicates significant barriers to healthcare access, satisfying the inability to attain appropriate medical management factor. This delay in diagnosis allowed the osteoarthritic process to progress without intervention, resulting in permanent worsening of the conditions through continued occupational stress on undiagnosed degenerative joints.
The % contribution of the causes is 100% and significant.
