Diagnosis: Osteoarthritis
Basis of diagnosis: The diagnosis was made in the Diagnostic Assessment by Dr Thomas Perkins dated 2 October 2025, and is supported by an X-ray right shoulder report by the radiologist, dated 22 September 2011.
I am satisfied this is the appropriate diagnosis.
In determining your claim for this condition, I have applied the SOP:
Statement of Principles concerning Osteoarthritis (Balance of Probabilities) (No. 62 of 2017)

- for osteoarthritis of a hip joint only, having femoroacetabular impingement syndrome of the affected joint, before the clinical onset of osteoarthritis in that joint
I have noted your contention as to the cause of this condition. The available evidence indicates, I have noted your contention to the cause of your condition. Your service medical records indicate that you presented to the health facility with deep aching pain in the right shoulder with stiffness, grinding and catching, worse with overhead work, lifting and lying on the right side, and pain that woke you at night on 20 September 2011.
The diagnosis was made on the history of deep aching pain, stiffness and grinding of the right shoulder with night pain, the examination findings of crepitus and painful restriction of external rotation and abduction, and X-ray on 22 September 2011 showing narrowing of the glenohumeral joint space, an inferior humeral head osteophyte and subchondral sclerosis. An orthopaedic surgeon confirmed right glenohumeral osteoarthritis on 10 October 2011. This meets the Statement of Principles definition of osteoarthritis, a degenerative joint disease with loss of articular cartilage and bony changes.
This has then led to further investigations and the diagnosis of your condition of Osteoarthritis. I have accepted your condition of Osteoarthritis.
Having considered your service records and the available medical evidence, I am satisfied the SOP is met and that this condition is related to your peacetime service.
I have therefore accepted that this condition is related to your service with effect from 12 September 2011.

I have noted your contention as to the cause of this condition. The available evidence indicates, I have noted your contention to the cause of your condition. Your service medical records indicate that you presented to the health facility with deep aching pain in the right shoulder with stiffness, grinding and catching, worse with overhead work, lifting and lying on the right side, and pain that woke you at night on 20 September 2011.
The diagnosis was made on the history of deep aching pain, stiffness and grinding of the right shoulder with night pain, the examination findings of crepitus and painful restriction of external rotation and abduction, and X-ray on 22 September 2011 showing narrowing of the glenohumeral joint space, an inferior humeral head osteophyte and subchondral sclerosis. An orthopaedic surgeon confirmed right glenohumeral osteoarthritis on 10 October 2011. This meets the Statement of Principles definition of osteoarthritis, a degenerative joint disease with loss of articular cartilage and bony changes.
After the condition arose, it was worsened during your service. Rheumatoid arthritis continued to involve the right glenohumeral joint after onset, with synovitis on ultrasound on 5 February 2019, before the documented worsening on 18 June 2019. The septic arthritis of the right glenohumeral joint of 14 February 2000 preceded the worsening on 18 June 2019. The intra-articular Hill-Sachs and glenoid rim fractures of 3 April 1993 preceded the worsening on 18 June 2019. The haemarthroses of the right glenohumeral joint of April 1993 and May 2008 preceded the worsening on 18 June 2019. Gout continued to involve the right shoulder, with a further crystal-proven attack on 11 November 2016, before the worsening on 18 June 2019. The fall of 3 November 1999 and the re-dislocation of 14 May 2008 each fall within the 25 years before the worsening, from 18 June 1994 to 18 June 2019. The acute chondral defect of the humeral head shown on 30 August 2008 falls within the 25 years before the worsening, from 18 June 1994 to 18 June 2019. The acute lateral meniscal tear of the left knee of 17 August 2004 falls within the 25 years before the worsening on 18 June 2019. The frostbite of the right shoulder of 21 February 2008 preceded the worsening on 18 June 2019. The malunion of the right humeral neck persisted unchanged from 2000, so disordered joint mechanics were present for more than five years before the worsening on 18 June 2019. The avascular necrosis of the humeral head progressed to subchondral collapse on MRI on 21 March 2018, before the worsening on 18 June 2019. The sustained power grip of 1990 to 2004, more than ten years within a continuous 15-year period, preceded the worsening on 18 June 2019. Vibrating percussive tool use on more days than not from 1994 to 2004 alone amounts to ten years within the 25 years before the worsening, from 18 June 1994 to 18 June 2019. The asymmetric gait present since 2005 continued for more than five years before the worsening on 18 June 2019. The lifting of about 190,000 kilograms from 1990 to 2000 preceded the worsening, which occurred within 25 years of that period. The carrying of about 4,400 hours from 1990 to 2000 preceded the worsening, which occurred within 25 years of that period. The ladder and stair climbing of 2000 to 2006 was a continuous period of more than five years within the 25 years before the worsening on 18 June 2019. You remained overweight, with a BMI of 31.4 in 2019, for more than ten years before the worsening on 18 June 2019. Your waist circumference exceeded 102 centimetres throughout the ten years before the worsening, from 18 June 2009 to 18 June 2019, measuring 110 cm in 2019. Your waist circumference exceeded 88 centimetres throughout the ten years before the worsening, from 18 June 2009 to 18 June 2019. The kneeling and squatting of 1990 to 1997 preceded the worsening, which occurred within 25 years of that period. The internal derangement of the left knee of 2004 persisted before the worsening on 18 June 2019. Chondromalacia patellae of the left knee, diagnosed in 1991, preceded the worsening on 18 June 2019. The reduced pain sensation and proprioception of the right shoulder from the 1993 brachial plexopathy persisted before the worsening on 18 June 2019. Paget's disease of the right scapula and proximal humerus remained active, with alkaline phosphatase of 380 U/L in 2018, before the worsening on 18 June 2019. Acromegaly, present from 2008 until surgery in 2012, preceded the worsening on 18 June 2019. The dislocations of 1993 to 2008 occurred more than one year before the worsening on 18 June 2019. Femoroacetabular impingement syndrome of the left hip, diagnosed in 2009, preceded the worsening on 18 June 2019. In captivity in April 1993 the dislocated right shoulder was left unreduced for five days, and arthroscopy was delayed until August 1993; in East Timor in 1999 the humeral neck fracture could not be reduced or fixed in theatre and healed malunited; and after the re-dislocation in Afghanistan in May 2008 specialist review was delayed until your return.
This has then led to further investigations and the diagnosis of your condition of Osteoarthritis (Worsening). I have accepted your condition of Osteoarthritis (Worsening).
Having considered your service records and the available medical evidence, I am satisfied the SOP is met and that the worsening of this condition is related to your peacetime service.
I have therefore accepted that the worsening of this condition is related to your service with effect from 18 June 2019.
