DECISION AND ORDER 

Before: 

CHRISTOPHER J. GODFREY, Chief Judge 

ALEC J. KOROMILAS, Alternate Judge 

JAMES A. HAYNES, Alternate Judge 

JURISDICTION 

On March 9, 2015 appellant, through counsel, filed a timely appeal from a November 24, 

2014 merit decision of the Office of Workers’ Compensation Programs (OWCP). Pursuant to 

the Federal Employees’ Compensation Act1

 (FECA) and 20 C.F.R. §§ 501.2(c) and 501.3, the 

Board has jurisdiction over the merits of this case. 

ISSUE 

The issue is whether appellant met her burden of proof to establish a right knee condition 

causally related to factors of her federal employment. 

On appeal, counsel contends that nothing within OWCP’s decision negates the evidence 

or argument submitted with appellant’s request for reconsideration. 

FACTUAL HISTORY 

On October 30, 2013 appellant, then a 38-year-old letter carrier, filed an occupational 

disease claim (Form CA-2) alleging that she sustained a right knee condition due to factors of her 

                                                             1

 5 U.S.C. § 8101 et seq.

federal employment, including walking more than six hours per day, standing more than two 

hours per day, walking up and down steps, and pushing and pulling over 50 pounds. 

In an October 24, 2013 report, Dr. John Mitamura, a Board-certified orthopedic surgeon, 

diagnosed a torn medial meniscus of the right knee and opined that it was causally related to 

appellant’s work as a mail carrier. He indicated that appellant walked six hours per day, over 

hills and up and down stairs, while delivering mail for the employing establishment. 

Dr. Mitamura noted that appellant had some additional injury to the knee in 2003, but no formal 

case was established at that time. In an October 24, 2013 work excuse note, he advised that 

appellant was unable to work due to internal derangement of the right knee. On November 13, 

2013 Dr. Mitamura indicated that a magnetic resonance imaging (MRI) scan of the right knee 

demonstrated significant tearing and extrusion of the medial meniscus, as well as joint effusion 

and lateral subluxation of the patella with chondromalacic changes. He diagnosed torn meniscus 

with patellar subluxation and chondromalacic changes and advised that appellant was totally 

disabled for work. 

In a December 24, 2013 letter, OWCP notified appellant of the deficiencies of her claim 

and afforded her 30 days to submit additional evidence. 

Appellant submitted a December 10, 2013 report from Dr. Mitamura who advised that 

she was not able to work “because she has to lift many pounds in the workplace.” Dr. Mitamura 

recommended right knee surgery and a 10-pound weight restriction on lifting at work. Appellant 

further submitted physical therapy notes dated November 20 through December 30, 2013. 

By decision dated January 30, 2014, OWCP denied the claim as the medical evidence 

failed to establish a causal relationship between appellant’s condition and factors of her federal 

employment. 

On September 30, 2014 appellant, through counsel, requested reconsideration and 

submitted physical therapy notes dated January 9 through April 23, 2014. 

In a November 13, 2013 report, Dr. Mitamura released appellant to work on 

November 18, 2013 with the following restrictions: no lifting, bending, kneeling, or carrying 

more than 10 pounds; no standing, climbing, long walks, pushing, or pulling. 

On January 9, 2014 Dr. Mitamura diagnosed torn medial meniscus based on an 

October 31, 2013 MRI scan demonstrating tearing of the medial meniscus. He noted that 

appellant would return to work with the following restrictions: repetitive lifting, pushing, and 

pulling no more than 30 pounds; walking and carrying no more than 2.5 hours per day; standing 

no more than 3 hours per day. 

In a statement dated February 14, 2014, the employing establishment indicated that 

appellant had returned to full-time, modified duty with restrictions effective January 27, 2014. 

In reports dated February 6 through May 1, 2014, Dr. Mitamura reiterated his diagnoses 

and recommendation for right knee surgery. On March 6, 2014 he stated that appellant had a 

right knee injury from her work as a mail carrier. Dr. Mitamura opined that “repetitive kneeling 

and stair climbing put stress upon the meniscus creating meniscal tear.” He reasoned that it was 

“well known that the flexion and pressure of the knee against the cartilage on a repetitive basis 
3

creates stress to the knee and this had led to the stress creating meniscal tearing.” On April 3, 

2014 Dr. Mitamura indicated that appellant felt “enough improvement to return to full duty” and 

he recommended her “for return to full work.” 

By decision dated November 24, 2014, OWCP denied modification of its prior decision. 

LEGAL PRECEDENT 

An employee seeking benefits under FECA2 has the burden to establish the essential 

elements of his or her claim, including the fact 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 period of FECA, and that an injury3

 was sustained in the performance of duty. These 

are the essential elements of each compensation claim, regardless of whether the claim is 

predicated upon a traumatic injury or an occupational disease.4

 

To establish that an injury was sustained in the performance of duty in a claim for 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.5

 

Causal relationship is a medical issue and the medical evidence generally required to 

establish causal relationship is rationalized medical evidence. The opinion of the physician must 

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

reasonable medical certainty and must be supported by medical rationale explaining the nature of 

the relationship between the diagnosed condition and the specific employment factors identified 

by the employee.6

 

ANALYSIS 

The Board finds that appellant did not meet her burden of proof to establish a claim that 

federal employment factors caused or aggravated her right knee condition. Appellant identified 

the factors of employment that she believed caused the condition, including walking, standing, 

climbing stairs, and pushing and pulling over 50 pounds at work, which OWCP accepted as 

factual. However, in order to establish a claim that she sustained an employment-related injury, 

                                                             2 Id.

 OWCP regulations define an occupational disease or illness as a condition produced by the work environment 

over a period longer than a single workday or shift. 20 C.F.R. § 10.5(q).

she must also submit rationalized medical evidence which explains how her medical condition 

was caused or aggravated by the implicated employment factors.7

 

In an October 24, 2013 report, Dr. Mitamura diagnosed a torn medial meniscus of the 

right knee and opined that it was causally related to appellant’s work as a mail carrier. He 

indicated that appellant walked six hours per day, over hills and up and down stairs, while 

delivering mail for the employing establishment. On December 10, 2013 Dr. Mitamura advised 

that she was not able to work “because she has to lift many many pounds in the workplace.” On 

March 6, 2014 he opined that “repetitive kneeling and stair climbing put stress upon the 

meniscus creating meniscal tear.” Dr. Mitamura reasoned that it was “well known that the 

flexion and pressure of the knee against the cartilage on a repetitive basis creates stress to the 

knee and this had led to the stress creating meniscal tearing.” He failed, however, to provide a 

rationalized opinion explaining how the specifically identified factors of appellant’s federal 

employment, such as walking, standing, climbing stairs, and pushing and pulling over 50 pounds 

at work, caused or aggravated her right knee condition. Dr. Mitamura noted that appellant’s 

condition occurred while she was at work, but such generalized statements do not establish 

causal relationship because they merely repeat appellant’s allegations and are unsupported by 

adequate medical rationale explaining how her physical activity at work actually caused or 

aggravated the diagnosed conditions.8 The Board has held that the mere fact that appellant’s 

symptoms arise during a period of employment or produce symptoms revelatory of an 

underlying condition does not establish a causal relationship between appellant’s condition and 

her employment factors.9 Dr. Mitamura did not explain the reasons why particular work factors 

caused or aggravated meniscal tearing or any other right knee condition. Other reports from him 

are of limited probative value as they do not specifically address whether particular work factors 

caused or contributed to a diagnosed medical condition.10 Thus, the Board finds that the medical 

evidence from Dr. Mitamura is insufficient to establish appellant’s claim. 

In support of her claim, appellant also submitted physical therapy notes dated 

November 20, 2013 through April 23, 2014. These documents do not constitute competent 

medical evidence as they do not contain rationale by a physician relating appellant’s disability to 

her employment.11 As such, the Board finds that appellant did not meet her burden of proof with 

these submissions. 

As appellant has not submitted sufficient rationalized medical evidence to support her 

allegation that she sustained an injury causally related to the accepted employment factors, she 

failed to meet her burden of proof to establish a claim. 

                                                             7 See A.C., Docket No. 08-1453 (issued November 18, 2008). 

8 See K.W., Docket No. 10-98 (issued September 10, 2010). 

9 See Richard B. Cissel, 32 ECAB 1910, 1917 (1981); William Nimitz, Jr., 30 ECAB 567, 570 (1979). 

10 See Jaja K. Asaramo, 55 ECAB 200 (2004) (medical evidence that does not offer any opinion regarding the 

cause of an employee’s condition is of diminished probative value on the issue of causal relationship). 

11 See 5 U.S.C. § 8101(2). Section 8101(2) of FECA provides as follows: “(2) ‘physician’ includes surgeons, 

podiatrists, dentists, clinical psychologists, optometrists, chiropractors, and osteopathic practitioners within the 

scope of their practice as defined by State law.” See also Paul Foster, 56 ECAB 208, 212 n.12 (2004).

On appeal, counsel contends that nothing within OWCP’s decision negates the evidence 

or argument submitted with appellant’s request for reconsideration. Based on the findings and 

reasons stated above, the Board finds counsel’s arguments are not substantiated. 

Appellant may submit new evidence or argument with a written request for 

reconsideration to OWCP within one year of this merit decision, pursuant to 5 U.S.C. § 8128(a) 

and 20 C.F.R. §§ 10.605 through 10.607. 

CONCLUSION 

The Board finds that appellant has not met her burden of proof to establish a right knee 

condition causally related to factors of her federal employment.
