Other evidence:-
52The plaintiff tendered the chronology and medicals as well as tax returns, wage records and attendant care figures. The defendant tendered its medical reports. At the close of the evidence a great bundle of material from Quality Occupational Health, a workers compensation rehabilitation provider, was tendered [exhibit 10] without any attempt to indicate what parts of this voluminous material was relevant or relied upon. Indeed both parties used the shotgun approach in their medical evidence, firing it out for the court to do the investigative work and come to a conclusion. One trouble with this approach, apart from being forensically bad conduct, is that it means the court is being asked to resolve differences of opinion without any particular point of reference other than the evidence of the plaintiff and Ms Cheema. As far as exhibit 10 is concerned I do not see that it is my task to wade through a 2cm thick bundle of reports on the off chance that they may contain something of advantage or disadvantage to either party. As my attention was not drawn to any aspect of any of this material I have had no regard to it.
53I agree with defence submissions that the evidence of the plaintiff's attempts to find work lack substance. There is no evidence of any resume, the names of persons contacted for work, the type of work in question and what was physically involved in that work. The only job description of work Mr Grewal applied for, unsuccessfully, was a recent pizza delivery job.
54Dr Giblin, the treating orthopaedic surgeon, gave a final assessment in July 2012 (his 23rd report). His opinion remained the same as before that the plaintiff had sustained an injury to his left knee involving the articular cartilage of the retro-patelar surface and that he was also developing similar symptoms in his right knee due to favouring the left knee, which tended to suggest an aggravation of underlying degenerative change. He was unfit for work involving prolonged standing, squatting, kneeling, climbing stairs and ladders and the like. Further surgical intervention of the left knee was not anticipated but he may require arthroscopy of the right knee at a cost of $12,000. He would need to see his GP three times a year and may require occasional physiotherapy in blocks of four to six treatments. He recommended domestic assistance for 4 hours a fortnight for gardening and lawn mowing only.
55The Plaintiff was also seen by a number of other orthopaedic surgeons, Dr Herald in 2007, Dr Conrad in 2009, 2011 and 2012 and Dr Deveridge in 2009, 2010 and 2012.
56Dr Herald's report does not add much to the overall picture basically confirming the initial diagnosis of Dr Giblin. Drs Conrad and Deveridge's reports are summed up in each of their final reports.
57On 27 Nov 2012 Dr Conrad said:-
OPINION:- This man was involved in a motor vehicle accident on the 2nd August 2007. As a result he sustained some chest trauma, which has mainly resolved, but he has some occasional stiffness present. He injured his left shoulder and has some residual stiffness in his left shoulder, but full movements on examination. His predominant injury was to his left knee and both MRI scan and arthroscopy have shown articular damage to the retropatellar surface and he has ongoing pain and stiffness in the left knee despite arthroscopic trimming. Undoubtedly, this is due to the development of patellofemoral arthritis, which will gradually deteriorate over the years.
Due to favouring his left leg, he has sustained pain and stiffness in the right knee and he continues to need physiotherapy on a needs basis.
In my view, he is not able to work fulltime as a storeman, doing unrestricted work as he did at Australian Pharmaceutical Industries. He might be able to do light storework or depot work or cleaning work doing twelve to fifteen hours per week in a position where he is able to stand or sit at will, not lift or carry anything more than five kilograms in weight, not go up and down stairs or ladders or squat or kneel.
This should all be part of a structured rehabilitation program.
As previously stated, undoubtedly he will develop arthritis in the left knee, however it is difficult to give a timeframe or quantify this.
Should his wife not be able to assist with the heavier part of housework, cooking and cleaning, he might need about six hours per week of Home Care assistance.
His prognosis is guarded.
58Dr Deveridge on 28 November said:-
PHYSICAL EXAMINATION:- There was mild left sided antalgia as previously noted. He can still only perform a half squat. Left knee joint - there is some low anteromedial joint line tenderness but no effusion. The presence of minor lateral patella tracking with irritability and crepitation on motion was again observed. He has a limited range of motion from 0° to 125°. There was no ligamentous instability. McMurray's sign is negative. There is mild thigh muscle wasting as previously noted. Calf girth measurements were equal.
Right knee joint - also unchanged with mild anterior joint line tenderness but no effusion. There was a good range of motion from 0° to 135° without significant patella mal tracking or crepitation. Left heel - he has some focal tenderness consistent with a plantar fasciitis. Both hip joints were fully mobile. Left shoulder joint - contour is preserved and there is a full range of motion. Once again he experienced some low-grade discomfort with full flexion, abduction and external rotation.
OPINION:- Your client remains moderately disabled with chronic left knee joint pain, intermittent swelling, stiffness and some loss of agility. Diagnosis remains consistent with post traumatic patellofemoral chondromalacia with mal tracking.
(As previously reported, I did not consider that his other complaints were causally related to the subject motor vehicle accident, including the right knee, hip, spine and left foot conditions).
On the balance of probabilities, residual disability in the left lower limb is attributable to the injuries sustained on 2.8.2007. No significant pre-existent or pre-disposing conditions were identified. He has some mild symptoms but no measurable loss of function relating to a soft tissue injury at the left shoulder, sustained in the same accident.
As a result of the left knee injury, he is permanently unfit for the usual work tasks of a storeperson and probably also for the tasks of a forklift operator. He could lift up to 5kg at bench level on a regular basis and up to 10kg occasionally. He should not perform any repetitive lifting from ground level. He needs to rest from weight bearing at least every 30 minutes or so. He cannot work in awkward knee positions, kneeling, crouching, nor can he regularly negotiate stairways. He should keep away from steep inclines, rough and uneven surfaces. He should avoid all impact activities. He is fit for light to moderate work with these restrictions. Any return to work would need to be graduated to allow conditioning, and a reasonable starting point would be four hours a day on five days a week, bearing in mind the above restrictions. I doubt if he could function as a truck driver within a properly equipped vehicle with only driving duties (he would inevitably be required to climb in and out of the cabin and fix loads). He could function as a bus driver or courier, again with the above restrictions and a graduated return to work. He has some limitations on activities of daily living and is reasonably receiving some assistance for heavier domestic chores and lawn maintenance.
As previously reported, he could still come to one or possibly two further arthroscopic chondroplasty and debridement procedures in the foreseeable future. I have provided costs of surgery, which may be updated by CPI. As previously reported I would not recommend a tubercle osteotomy. He should continue with his own exercise and stretching programme and he is familiar with patella taping. Occasional sessions of physiotherapy ($75 per session) could be provided at times of future relapse. He does not require ongoing treatment for the left shoulder condition.
His injuries are chronic and stabilised. He has reached maximal medical improvement. The condition has been medically stable for the previous three months and it is unlikely to change by more than 3% WPI in the next 12 months with or without further medical treatment. The prognosis for the left knee injury remains guarded.
59There is a dispute on the Plaintiff's psychiatric condition. In that regard there are a number of reports from Dr T O Clarke for the plaintiff and Dr S Smith for the Defendant. There is also a report from Dr Prior prepared as a MAS assessment. It would be a reasonable summary of the situation that Drs Smith and Prior are at odds with Dr Clarke who opines that the plaintiff is suffering from Chronic PTSD. Dr Prior, in May 2011, found Mr Grewal suffering from a Chronic Adjustment Disorder with Anxious and Depressed Mood.
60Dr Smith found in June 2012 that :-
Mr Grewal has not developed a formal psychiatric disorder in response to the motor vehicle accident that occurred on 2 August 2007. I did not find clear and convincing clinical evidence to support a formal psychiatric disorder ... .
I respectfully disagree with the opinions expressed by Ms Angela Parasher that Mr Grewal sustained a Post-traumatic Stress Disorder. The symptomatologies that he experienced did not equate to the development of a Post-traumatic Stress Disorder. In this regard I agreed with the opinion of Dr Prior who also found no clinical evidence for a Post-traumatic Stress Disorder.
I respectfully disagree with the opinion of Dr Prior that Mr Grewal has experienced a Chronic Adjustment Disorder with Depressed and Anxious Mood. Any symptomatologies experienced by Mr Grewal in my opinion have been but normal variants in response to the accident in question.
In my opinion Mr Grewal's presentation is not consistent with a Major Depressive disorder, Generalised Anxiety Disorder nor Panic Disorder. He displays marked avoidant and dependent behaviour. One would have anticipated significant improvement to have occurred given the length of time that has elapsed since the injury took place.
61Disagreement between Dr Clarke and Dr Smith in a forensic situation is something I have experienced in other proceedings involving, in one instance, concurrent evidence. Fortunately in the present case there is another opinion, perhaps of a more independent nature, that of Dr Prior's MAS assessment. Whilst Dr Clarke had other medical material available, it was all from the plaintiff's practitioners, whereas Dr Prior and Dr Smith had material from both sides. In my view the most reasonable approach to take is reflected in Dr Prior's report. In his report Dr Prior says that :-
He drove alone to the assessment venue, a journey of half an hour. He was familiar with the location of the assessment venue. When asked how the road journey to the assessment was he said "okay". When asked about his attitude to coming to the assessment he said "okay".
He reported taking Panadol Osteo, a simple analgesic agent, on the morning of the assessment and his usual anti-hypertensive medication. He denied substance intake. There was no evidence of substance intoxication or clinical withdrawal. He was fully alert and conscious. He was not sedated.
His grooming, hygiene levels and attire were within normal limits. His hair was worn neatly. He was clean shaved. He wore spectacles. He was neatly dressed. He had a thick chain bracelet on one wrist and wore a ring on a finger. He carried a bag of x-rays with him into the examination room.
He displayed frequent pain behaviour, flexing and extending his knees and his feet, moving sideways in his chair, standing to stretch and changing chairs at one stage during the assessment. When asked to rate his pain levels on a subjective scale where zero is no pain and ten is the maximum pain imaginable, he rated his pain during the assessment as three to four out often.
Rapport was established. There was no psychomotor retardation noted. He greeted me warmly. He said goodbye in a friendly fashion at the end of the assessment. Initially in the assessment he clenched his hands in an agitated fashion for a period but then this ceased. He occasionally sighed throughout the assessment. He spoke spontaneously and coherently at normal rate and volume. He spoke in normal detail and at normal length. His affect was dysphoric. His affective range was diminished. He did not display irritability or impatience. He was able to smile appropriately on several occasions. His thought form was normal. There were no abnormal thought contents or perceptual abnormalities.
Clinical tests of attention, concentration, orientation, and short term memory revealed these to be intact.
The history elicited was internally consistent. The history elicited was consistent with the mental status examination.
Dr S Dalton, in a report dated 9 December 2010, mentions "significant psychological overlay".
Treating GP, Dr P Singh, in a Motor Accidents Authority medical certificate dated 10 March 2008, makes no psychiatric diagnosis, nor does he mention any psychiatric symptoms.
Psychiatrist, Dr S Smith, in a report dated 8 November 2010, mentions "initially ... acute stress reaction ... substantially resolved ... no longer demonstrates diagnostic criteria for Acute Stress Disorder".
Psychiatrist, Dr T Oldtree Clark, in a report dated 12 May 2010, mentions "Post-Traumatic Stress Disorder with severe depression".
Recent treating psychologist, A Parasher, in a report dated 20 Juiy 2010, mentions "depression/anxiety and Post-Traumatic Stress Disorder symptoms".
I found no evidence, historically or currently, of Post-Traumatic Stress Disorder. I found no evidence, historically or currently, of a severe depression.
The "depression/anxiety" and "PTSD symptoms" mentioned by recent treating psychologist, A Parasher, would be consistent with an Adjustment Disorder. However, they are not consistent with the full criteria for Post-Traumatic Stress Disorder or a Major Depressive Disorder.
He does not currently nor has he historically, on the history I elicited from him and the history he related spontaneously, fulfilled diagnostic criteria for a Post-Traumatic Stress Disorder.
Because of his affective and anxiety symptoms which he currently has and has had in the long term, which do not fulfil the diagnostic criteria for a Post-Traumatic Stress Disorder nor a Major Depressive Disorder, I have redefined the diagnosis as being one of a chronic Adjustment Disorder with Anxious and Depressed Mood.
The cause of the above diagnosis is his pain and physical limitations and consequences of these including changes to his social and recreational activities, his inability to work and inability to find work, together with the motor vehicle accident itself.
62Mr Grewal was seen by a psychiatrist, Dr Edwards in September 2007 for the defendant. He found that the plaintiff met the DSM IV criteria for Acute Stress Reaction with sleep disturbance, nightmares, headaches and some anxiety but here were also some underlying personality and relationship difficulties unrelated to the MVA. He was fit, psychologically, for pre accident duties.
63In my view the evidence does not support a diagnosis of Chronic PTSD as that illness is understood. Having heard the plaintiff, I can see why Dr Smith reached the conclusions he came to and I don't accept the submission that Mr Grewal's behaviour in cross examination is necessarily evidence of a serious underlying mental condition. Ms Parasher's qualifications are in counselling and whilst what she says in that field is unexceptionable, I do not consider her qualified to give what is in effect a psychiatric diagnosis.
64The MAS also carried out an Attendant Care Service (ACS) assessment by Ms C James on 26 Jan 2011. She assessed a need for such services for Mr Grewal as being required for 4 hours per week to 14 March 2008 and 2.85 hours per week since. A claim is made for past ACS of 10 hrs per week at $22.00 per hour and for the future of 8 hrs per week for 40 years at either the rate of $40 per hour, paid or $26.50 per hour, unpaid. That does not include a claim for past and future lawn mowing costs. I note that in September 2010, Dr McGroder, an MAS assessor in regard to ACS issues said although some assistance in the past and for the future would be required, Mr Grewal could do considerably more than the amount of activities he alleges and he questioned whether a time frame of 10 hours assistance per week was realistic. I agree such a figure is not realistic.
65He saw Dr Noll an orthopaedic surgeon, in March 2009 and December 2012. In his final report Dr Noll said that :-
The general appearance of his lower extremities was normal. It should be noted that at the time of the previous assessment he was found to have obvious relative wasting of the left thigh muscles as compared to the right. At today's assessment however there was no evidence of any muscle wasting and circumferential measurement of the thighs and calves did not reveal any significant discrepancy between the two sides. Muscle strength in relation to both lower extremities was normal on clinical testing.
The range of movement of the left knee was from 0 to 140° which was equivalent to the range of movement on the left side. Collateral and cruciate ligaments were intact. There was mild patellofemoral crepitus bilaterally. There was no swelling of the left knee and no evidence of any effusion or synovial thickening.
He had a full range of pain free movement of his ankles and hindfeet with the ranges of movement being equivalent on the two sides. He reported some localised tenderness over the plantar aspect of the left heel.
He complains of ongoing left knee pain but, other than mild patellofemoral crepitus, clinical assessment today did not reveal evidence of any significant abnormality. There was no evidence of thigh muscle wasting at today's assessment; the left thigh muscle wasting noted at the time of the initial assessment has resolved completely.
He reports having some ongoing left shoulder pain but was noted to have a normal range of movement of his left shoulder at today's assessment. An x-ray of the left shoulder in March 2011 revealed evidence of some calcification in relation to the supraspinatus part of the rotator cuff (calcific tendinosis) which is a constitutional disorder unrelated to trauma. He was noted to have a normal range of shoulder movement at today's assessment.
Mr Grewal may continue to have some ongoing left knee symptoms arising from the degenerative changes in relation to the patellofemoral joint. Significantly however he has regained normal left thigh muscle bulk which suggests that there has been marked improvement in left knee function. He requires no further investigations or specific treatment in relation to his left knee. He may continue to experience some ongoing symptoms in relation to his left shoulder associated with the calcific tendinosis noted on x-ray but in my opinion this does not relate to the subject accident.
In my opinion Mr Grewal is fit to undertake full time work. It would probably be reasonable for him to avoid work which would require repetitive squatting or climbing up and down ladders, which would possibly result in aggravation of patellofemoral symptoms. There is however no evidence of abnormality of the tibio-femoral component of his left knee and it is unlikely that he would experience any symptoms associated with walking or standing for any length of time.
He would in my opinion be fit to undertake most routine domestic and garden maintenance activities including vacuuming and lawn mowing. He does not require any paid assistance in this regard. I would accept that he would possibly have difficulty with some domestic maintenance activities which would require climbing up and down ladders and in this regard he would possibly require sporadic paid assistance.
66Mr Grewal saw Dr Dalton, a rehabilitation physician in December 2010 and July 2012. Dr Dalton provided three reports, one involved comment on other experts.
67In his first report, Dr Dalton noted amongst other things that:-
The report from his physiotherapist suggests that Mr Grewal has been excessively injury focused and has been non-compliant with his exercise programme in the past. This reinforces my view that there is significant psychological overlay in this case and avoidant behaviour on the part of Mr Grewal. I find that there is no reasonable basis for his claim that he is unable to undertake a range of domestic and household activities. I find it most surprising that Mr Grewal does very little in the way of housework or assisting his wife who works full-time. His claim that he cannot stand for long periods to wash dishes or hang out washing is inconsistent with the underlying condition affecting his left knee and reflects his excessive disability focus and functional overlay. He presents as being poorly motivated and despite his claims that he was getting more benefit from a supervised exercise programme there is no evidence to suggest that that was the case. ... .
The inconsistencies and non-organic clinical signs noted during assessment suggest that there is significant exaggeration and embellishment of his disabilities at this time and it is my view that Mr Grewal is not nearly as physically disabled as has been claimed. To what extent his pain behaviour reflects fear avoidance is unclear but reports from his physiotherapist and the results of previous functional assessments indicate that lack of motivation and noncompliance have been significant barriers to his physical rehabilitation previously.
In my opinion there is no need for domestic or household assistance arising from his injuries. If anything Mr Grewal should be encouraged to participate more in the normal household activities at home to reduce the workload on his wife. ... .
His symptoms are no doubt aggravated by the fact that he has now become deconditioned and is overweight and on that basis a weight loss and exercise programme should see a reduction in symptoms and an increase in functional tolerances. There is significant psychological and functional overlay present. Reasons for this are unclear and may reflect fear avoidance behaviour, anxiety or simply Abnormal Illness Behaviour. His reported level of symptoms and disabilities are disproportionate to injuries received and the pathology which has been demonstrated and are also inconsistent with objective clinical findings on examination. No underlying organic pathology has been identified which would account for Mr Grewal's difficulties with weight bearing and functional limitations within the home.
He is fit for full-time sedentary and semi-sedentary work and has a number of transferable skills. He claims to be actively involved in job seeking but presents as being poorly motivated and disability focused.
68In a report of 5 May 2011 he was asked to comment on reports of Dr McGroder and Ms James the MAS assessors with whom he disagreed, Dr McGroder as to his diagnosis of chondromalacia patellae due to an impact injury and Ms James as to her assessment of some need for ACS because she had not given adequate consideration to the inconsistencies and discrepancies noted between his subjective complaints, fear avoidance and pain behaviours and the lack of objective findings on clinical examination.
69In his final report Dr Dalton said that:-
Little has changed with respect to this man's clinical findings on examination and his subjective complaints. He is still reporting chronic left anterior knee pain but is now reporting increasing pain in his right knee. He describes functional limitations with respect to walking distances, squatting and stair climbing. He indicated that he has continued to look for work but has been unsuccessful to date and he also reported symptoms of sleep disturbance and depressed mood.
As before I was struck by the lack of objective clinical findings with respect to Mr Grewal's left knee. There was no localised tenderness, no joint swelling and no disuse muscle atrophy. There was a noticeable absence of pain during the clinical examination and yet Mr Grewal presents with significant functional limitations which appear disproportionate to objective clinical findings.
I would not seek to alter my previous opinion in relation to Mr Grewal's clinical condition. As I have stated previously the only physical restriction which I would consider reasonable and consistent with the diagnosis of chondromalacia patellae and early patellofemoral arthritis is that Mr Grewal would have some difficulty with repetitive crouching, squatting and climbing but in my opinion he remains physically fit to undertake full-time employment. He would certainly benefit from a weight loss and exercise programme but his deconditioning most likely reflects his sedentary lifestyle and depressed mood.
I note the MAS Certificate of Dr Prior which considers that Mr Grewal suffers from a Chronic Adjustment Disorder with Anxious and Depressed Mood and that is consistent with my assessment of this man. However, as I have identified previously, there is considerable discrepancy between Mr Grewal's subjective complaints and claimed functional limitations and the lack of objective clinical signs. For someone who is reporting such significant restrictions with respect to squatting, climbing and walking one would expect there to be either objective clinical signs of synovitis or symptomatic arthritis of the affected knee, or alternatively one would expect signs of neuropathic pain and central sensitisation neither of which were apparent in this case. I therefore do not seek to alter the opinions expressed in my previous report dated 9th September 2010. Other than a self-directed exercise programme and weight loss I do not consider that any further physical treatment or rehabilitation is indicated now or in the foreseeable future. Given that this man has apparently undergone counselling I think that it is unlikely that he would benefit from further psychological intervention.
I believe that his depressed mood and general inactivity is closely related to the fact that he remains unemployed. Although he claims to be actively involved in job seeking I formed the view that he is poorly motivated and disability focused. Whether this reflects disillusionment and frustration at his failure to find work or whether this is a reflection of his Chronic Adjustment Disorder and the ongoing medicolegal process is unclear. However, my previous recommendations and opinions regarding to this man's current level of disability and prognosis for recovery and return to work has not altered.
Similarly I do not seek to alter my previous opinion with regard to Mr Grewal's functional limitations and whether or not the accident on the 2nd August 2008 has created a past or future need for domestic assistance. I would go so far as to suggest that Mr Grewal should be encouraged to become more functionally independent in the home. I think that this will benefit him physically and psychologically. Provision of ongoing domestic assistance will, in my view, reinforce this man's strong disability focus and illness behaviour and will be counterproductive in the long-term.
I would defer to independent psychiatric opinion in determining whether or not Mr Grewal is likely to benefit from psychological or psychiatric intervention but my view is that this man's physical and psychological recovery would be greatly assisted by a successful return to work programme. Unfortunately the fact that he has been unemployed since 2009 and has failed to find alternative employment is a poor prognostic indicator, particularly whilst he is still involved in the medicolegal process.
70I would agree with the defence submission that Mr Grewal's manner of giving evidence tends to suggest exaggeration and embellishment as observed and commented on by Dr Dalton. The fact of the matter is that Mr Grewal worked after this accident for almost 12 months on light duties which only ended when his employer had no further work. There is nothing to suggest that this situation could not have continued and that nothing caused by the defendant's negligence has prevented him from working to that level of employability.
71Whilst Dr Dalton deferred to psychiatric opinion, the weight of that opinion is that Mr Grewal is not so disabled psychiatrically that he cannot work or further that even in some sort of combination with his physical disabilities, he cannot work. He has an adjustment disorder with depressed mood and a physical disability that is not totally incapacitating and is far from unemployable.
72There is no doubt that the plaintiff's injury has reduced his employability on the open market and has limited the nature of the work he may be otherwise able to obtain if he was so motivated. However the evidence that Mr Grewal has made a reasonable effort to obtain work and mitigate his damages in that regard is sadly lacking. As to why his employment was terminated is not a matter about which there is any conclusive evidence. The fact that he was upset and disgruntled by that dismissal is not something that can be attributed to the defendant's actions.
