ISSUE

The issue is whether appellant has met his burden of proof to establish a medical condition 

causally related to the accepted factors of his federal employment.

FACTUAL HISTORY

On August 20, 2021 appellant, then a 58-year-old bulk mail clerk, filed an occupational 

disease claim (Form CA-2) alleging that he developed osteoarthritis in the hips and knees and 

degenerative disc disease in his lower back due to factors of his federal employment, including 

walking and standing on concrete for extended periods of time, continuous bending, twisting, and 

lifting of heavy trays of mail, and the operation of machines six days a week for 15 years. He 

indicated that he first became aware of his conditions on November 1, 2020 and realized their 

relation to factors of his federal employment on March 1, 2021. Appellant did not stop work.

Appellant submitted an undated statement indicating that he first noticed pain and stiffness 

in his back and hips the previous year but ignored it, believing that it was caused by his sleeping

position. He related that his condition worsened and caused difficulty sitting, sleeping, and 

performing his work duties. Appellant asserted that the cause of his conditions was due to the

years of walking and standing on concrete with constant bending and twisting. He related that an

orthopedic specialist examined him and administered injections to his back and hip, but he 

continued to have difficulty walking long distances and performing his work duties. 

An April 16, 2021 magnetic resonance imaging (MRI) scan report of appellant’s right hip 

noted an impression of mild degenerative changes at the right hip with no evidence of avascular 

necrosis (AVN) to the femoral head, fraying of the labrum without a discrete tear, and right 

hamstring tendon complex tendinopathy with low-grade partial avulsion of the tendon fibers. An 

MRI scan report of even date of his left hip noted an impression of severe osteoarthritis of the left 

hip, marked bone marrow edema in the femoral head greater than acetabulum which may relate to 

the osteoarthritis, suspicious for inflammatory arthritis, an appearance not typical for AVN in the 

left femoral head, a torn left acetabular labrum, and a bone fragment suggesting a displaced

acetabuli versus avulsion fracture from the acetabulum.

In a June 29, 2021 visit note, Dr. Christopher Merrell, Board-certified in physical 

medicine, noted that he performed a physical examination and diagnosed left hip joint pain, 

osteoarthritis of the hip, and lumbosacral spondylosis without myelopathy. He indicated that 

appellant reported that his chronic bilateral knee pain began with severe knee osteoarthritis that he 

developed while in the service. Dr. Merrell reviewed x-ray and MRI scan reports, ordered facet 

injections, and related that appellant has chronic low back pain, bilateral knee osteoarthritis, and 

hip pain which may require joint replacement.

In an August 25, 2021 development letter, OWCP informed appellant of the deficiencies 

of his claim. It advised him of the additional evidence needed to establish his claim and provided 

a questionnaire for his completion. In a separate development letter of even date, OWCP requested 

that the employing establishment provide additional information, including comments from a 

knowledgeable supervisor. It afforded both parties 30 days to respond.
3

Thereafter, appellant submitted an undated note from Dr. John Hulvey, Jr., a Boardcertified sports medicine practitioner, indicating that he had been treating appellant for several 

years for chronic bilateral knee pain secondary to advanced osteoarthritis. Dr. Hulvey noted that 

despite treating with physical therapy, anti-inflammatories, injections, and platelet-rich plasma, 

his pain continued to worsen. 

OWCP also received an April 25, 2002 position description and a March 22, 2019 work 

standard description. 

In an August 27, 2021 letter, an employing establishment supervisor, Y.R., controverted 

appellant’s claim, asserting that he had not asked for assistance due to his alleged conditions and 

had not provided any information or documentation. She related that his job duties included: 

lifting trays weighing up to 20 pounds for up to seven hours a day; pushing all-purpose containers 

or trucks up to 20 feet every 30 to 45 minutes; and bending to lift or push trays and bins. Y.R. 

asserted that appellant requested to be on the volunteer overtime list, chose to work a sixth day

each week, and was given 15-minute breaks and a lunch each day. 

An August 31, 2021 disability statement from the Department of Veterans Affairs indicated

that appellant has service-connected disabilities, including right knee patellofemoral osteoarthritis

with limited extension (40 percent disability), right shoulder residuals of acromioclavicular joint 

injury with arthritis and mild impingement (20 percent disability), left knee osteoarthritis (10 

percent disability), and hypertension (10 percent disability). 

In a September 8, 2021 work status report, Dr. Merrell diagnosed left hip joint pain and 

returned appellant to regular-duty work the following day. 

By decision dated October 4, 2021, OWCP denied appellant’s claim, finding that he had 

not submitted sufficient evidence to establish the implicated factors of employment. 

Consequently, it found that he had not met the requirements to establish an injury as defined by 

FECA.

On October 20, 2021 appellant, through counsel, requested a telephonic hearing before a 

representative of OWCP’s Branch of Hearings and Review, which was held on February 15, 2022. 

By decision dated April 7, 2022, OWCP’s hearing representative modified the October 4,

2021 decision to find that appellant had established the implicated employment factors. However, 

the claim remained denied because the medical evidence of record was insufficient to establish a 

medical diagnosis in connection with the accepted factors of his federal employment.

On May 19, 2022 appellant, through counsel, requested reconsideration of the April 7, 

2022 decision and submitted additional evidence.

In a May 6, 2022 report, Dr. Neil Allen, a Board-certified internist and neurologist, 

indicated that he reviewed appellant’s medical records and contacted him for a statement. 

Appellant related that he was a mail processing clerk for approximately 15 years when he began 

to experience worsening pain in his back, hips, and knees, and his duties included a quarter mile

walk and loading and unloading large trays of mail into a 150-foot-long processing machine. 

Dr. Allen noted that appellant engaged in continuous standing, walking, bending, pushing, pulling, 
4

lifting, and twisting while loading mail trays for two-hour periods before a 15-minute break, 

repeated 8 to 10 hours per day, six days per week. He observed that appellant underwent a total 

left hip arthroplasty in November 2021 and had service-related bilateral knee injuries in 1991, for

which he underwent total right knee reconstruction. Dr. Allen diagnosed acceleration of bilateral 

osteoarthritis of the hips, acceleration and aggravation of bilateral osteoarthritis of the knees, and 

acceleration of lumbar spondylosis.

Dr. Allen explained that arthritis is a failure and loss of articular cartilage surface and 

opined that the repetitive motions of appellant’s duties exacerbated his low back, right hip, and 

bilateral knee symptoms and resulted in local stress and the breakdown of the articular cartilage of 

his bilateral hips and knees and degeneration of the facet joints of his lumbar spine. The repetitive 

loading resulted in mechanical stress on the joint surfaces, which causedchronic inflammation and

chemical changes in the cartilage that accelerated the degradative process, specifically by 

activation of degradative enzymes aimed at destruction of the proteoglycan, which is responsible 

for cartilage resilience. Dr. Allen concluded that appellant’s osteoarthritis developed over time 

and was aggravated and accelerated by his occupational exposure, which required persistent 

loading of his lumbar spine and bilateral lower limbs and caused cartilage loss in his hips and 

knees, and sclerosis in his lumbar spine. He further opined that the aggravation of appellant’s 

conditions was permanent and, in the absence of adequate rest, was accelerated and aggravated 

beyond what would be expected from age-related degradation.

By decision dated August 11, 2022, OWCP modified its April 7, 2022 decision to find that 

the evidence of record was sufficient to establish a medical diagnosis. The claim remained denied, 

however, because the medical evidence of record was insufficient to establish causal relationship 

between appellant’s diagnosed conditions and the accepted factors of his federal employment.

LEGAL PRECEDENT

An employee seeking benefits under FECA3 has the burden of proof to establish the 

essential elements of his or her claim, including that the individual is an employee of the United 

States within the meaning of FECA, that the claim was timely filed within the applicable time 

limitation of FECA,4that an injury was sustained in the performance of duty as alleged, and that 

any disability or medical condition for which compensation is claimed is causally related to the 

employment injury.5 These are the essential elements of each and every compensation claim, 

regardless of whether the claim is predicated upon a traumatic injury or an occupational disease.6

To establish that an injury was sustained in the performance of duty in an occupational 

disease claim, an employee must submit the following: (1) a factual statement identifying 

employment factors alleged to have caused or contributed to the presence or occurrence of the 

disease or condition; (2) medical evidence establishing the presence or existence of the disease or 

condition for which compensation is claimed; and (3) medical evidence establishing that the 

diagnosed condition is causally related to the employment factors identified by the employee. 7

To establish causal relationship between the condition and the employment factors, the 

employee must submit rationalized medical opinion evidence.8 The opinion of the physician must 

be based on a complete factual and medical background of the employee, must be expressed in 

terms of a reasonable degree of medical certainty, and must be supported by medical rationale 

explaining the nature of the relationship between the diagnosed condition and the specific 

employment factor(s) identified by the employee.9 The weight of the medical evidence is 

determined by its reliability, its probative value, its convincing quality, the care of analysis 

manifested, and the medical rationale expressed in support of the physician’s opinion.10

In any case where a preexisting condition involving the same part of the body is present 

and the issue of causal relationship therefore involves aggravation, acceleration or precipitation, 

the physician must provide a rationalized medical opinion that differentiates between the effects 

of the work-related injury or disease and the preexisting condition.11

ANALYSIS

The Board finds that this case is not in posture for decision.

In his May 6, 2022 report, Dr. Allen noted that appellant’s work duties included: walking, 

bending, pushing, pulling, lifting, twisting, and dumping large trays of mail into a mail processing 

machine. He indicated that appellant underwent a total left hip arthroplasty in November 2021 

and had service-related bilateral knee injuries in 1991, after which he underwent total right knee 

reconstruction. Dr. Allen diagnosed acceleration of bilateral osteoarthritis of the hips, acceleration 

and aggravation of bilateral osteoarthritis of the knees, and acceleration of lumbar spondylosis. 

He opined that the repetitive motions of appellant’s duties resulted in local stress and breakdown 

of the articular cartilage of his bilateral hips and knees and degeneration of the facet joints of his 

lumbar spine. Dr. Allen explained that the repetitive loading and mechanical stress on the joint 

surfaces caused chronic inflammation and chemical changes in the cartilage that accelerated the

degradative process by activation of degradative enzymes aimed at destruction of the proteoglycan, 

which is responsible for cartilage resilience. He concluded that appellant’s osteoarthritis 

developed over time, was beyond expected age-related degradation, and was aggravated and 

accelerated by his occupational exposure due to persistent loading of his lumbar spine and bilateral 

lower limbs, which caused cartilage loss in his hips and knees and sclerosis in his lumbar spine.

Dr. Allen’sMay 6, 2022 provided a pathophysiological explanation as to how the accepted 

factors of employment caused the diagnosed back, hip, and knee conditions. While Dr. Allen’s

report is not completely rationalized to meet appellant’s burden of proof to establish his claim, it 

is, sufficient to require further development of his claim. 12

The Board notes that proceedings under FECA are not adversarial in nature, nor is OWCP 

a disinterested arbiter. While it is appellant’s burden of proof to establish the claim, OWCP shares 

responsibility in the development of the evidence.13 It has an obligation to see that justice is done.14

The case must, therefore, be remanded for further development of the medical evidence. 

On remand, OWCP shall refer appellant, a statement of accepted facts (SOAF), and the medical 

evidence of record to a specialist in the appropriate field of medicine. The referral physician shall 

provide a rationalized opinion on whether the diagnosed conditions are causally related to the 

accepted employment factors. If the physician opines that the diagnosed conditions are not 

causally related, he or she must explain with rationale how or why his or her opinion differs from 

that of Dr. Allen. Following this and other such further development as deemed necessary, OWCP 

shall issue a de novo decision.

CONCLUSION

The Board finds that this case is not in posture for decision.
