ISSUE

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

causally related to an accepted September 17, 2016 employment incident.

FACTUAL HISTORY

On July 23, 2014 appellant, then a 25-year-old city carrier associate, filed a traumatic injury 

claim (Form CA-1) alleging that, on that date, he twisted his left knee while entering a truck in the 

performance of duty. He stopped work that same day. OWCP assigned this claim OWCP File 

No. xxxxxx139, and on August 11, 2014 accepted it for left knee sprain. Appellant received 

compensation benefits until he returned to full-time, limited-duty work on November 28, 2014.

On September 30, 2016 appellant filed a notice of recurrence (Form CA- 2a), alleging a 

recurrence of disability causally related to the July 23, 2014 employment injury commencing on 

September 17, 2016. He noted that he had returned to light-duty work, but that after working his 

shift on September 17, 2016 he experienced soreness and pain in his injured knee. In an 

accompanying statement, appellant related that he believed that his pain was due to the original 

injury which never healed properly. He alleged that his doctor confirmed it was a recurrence of 

the original injury. 

By development letter dated October 7, 2016, OWCP informed appellant that additional

medical evidence was necessary to support his claim for a recurrence, and afforded him 30 days 

to submit evidence. In a response received by OWCP on November 2, 2016, appellant indicated

that even a light-duty letter carrier position was physical in nature. He related that his recurrence 

happened throughout the day on September 17, 2016 while he was hopping out of the truck and 

delivering mail. Appellant noted that these activities required that he twist and turn his knee. He 

also noted that he started his day by casing mail on his feet for roughly 90 minutes and he then 

performed his delivery route. Appellant related that his injury occurred throughout the day. He 

alleged that being on his feet all day put strain on the knee.

By letter dated November 7, 2016, OWCP informed appellant that his recurrence claim 

would be handled as a new traumatic injury claim, that a new claim would be administratively 

created using the Form CA-2a that appellant filed, and that a new case number would be assigned.

It thereafter assigned the new claim OWCP File No. xxxxxx533.

In a September 19, 2016 report, Dr. Steven A. Simonsen, appellant’s treating Boardcertified orthopedic surgeon, indicated that appellant was partially disabled.

In a September 26, 2016 report, Dr. Michael Setton, a Board-certified radiologist, 

interpreted an x-ray of the same date and found subacute sprain and high-grade partial tear of the 

distal fibular collateral ligament, no meniscal tear, articular cartilage, abnormality, occult osseous 

injury, or other ligament injury identified, and minimal joint effusion.

By report dated September 30, 2016, Dr. Simonsen noted that appellant had pain on varus 

stress to the lateral aspect of the knee. He also noted stiffness on palpitation to the distal fibular 

collateral ligament. In an attending physician’s report (Form CA-20) dated October 3, 2016,
3

Dr. Simonsen related that appellant was temporarily totally disabled from September 19, 2016 

until present. He noted that appellant gave a history of entering a truck at work and twisting his 

knee. Dr. Simonsen opined that appellant suffered a sprain of the left knee and plica syndrome, 

and indicated by checking a box marked “yes” that this injury was caused or aggravated by the 

employment activity described by appellant.

By development letter dated November 17, 2016, OWCP informed appellant that 

additional medical evidence was necessary to support his claim, and afforded him 30 days to 

submit the necessary information.

OWCP continued to receive medical evidence. In a September 19, 2016 treatment note,

Dr. James L. Marzec, a Board-certified orthopedic surgeon, stated that appellant reported a left 

knee exacerbation. He stated that he planned to get a magnetic resonance imaging (MRI) scan of 

appellant’s left knee, and that appellant would be out of work until the results were interpreted.

In an October 14, 2016 treatment note, Dr. Simonsen noted that appellant’s prior MRI scan 

in June 2015 showed a suggestion of red marrow hyperplasia. He listed diagnoses of high-grade 

partial tear of distal fibular collateral ligament of left knee/subacute sprain minimal joint effusion. 

In a November 4, 2016 report, Dr. Simonsen stated that appellant could return to sedentary work. 

In a progress report of the same date, he noted reinjury to lateral collateral ligament complex, firstdegree, no plica symptoms. Dr. Simonsen noted that this appeared to be related to appellant’s 

2014 injury. He diagnosed a high-grade partial tear of distal fibular collateral ligament of the left 

knee/subacute sprain minimal joint effusion. In a December 5, 2016 report, Dr. Simonsen noted 

that appellant continued to complain of left knee pain. He diagnosed chronic pain secondary to 

lateral collateral ligament complex tear.

By decision dated December 22, 2016, OWCP denied appellant’s claim as it determined 

that the medical evidence was insufficient to establish that the claimed medical condition was 

causally related to the accepted September 17, 2016 work incident. Specifically, it noted that the 

medical evidence submitted did not contain a well-reasoned medical opinion supported by 

objective medical findings as to exactly how the diagnosed medical conditions of left knee sprain, 

high-grade partial tear of the fibular collateral ligament of the left knee, left knee plica syndrome, 

left knee severe patella tilt, and left knee lateral collateral ligament complex tear were either 

directly caused or aggravated by the accepted work incident of September 17, 2016.

Appellant continued to submit progress reports from Dr. Simonsen. In reports dated 

January 18, February 23, and March 30, 2017, Dr. Simonsen noted that appellant continued to 

complain of pain in his left knee. He continued to diagnose work-related lateral collateral ligament 

complex tear with scarring and persistent pain, and continued to opine that appellant remained 

disabled.

On May 9, 2017 appellant, through counsel, requested reconsideration. Counsel argued 

that the medical evidence already submitted sufficiently proved a causal relationship. He noted

that Dr. Simonsen diagnosed a left knee sprain, high-grade partial tear of distal fibular collateral

ligament of the left knee, and a left knee lateral collateral ligament complex tear. Counsel

contended that Dr. Simonsen found objective findings of left knee pain, left knee effusion, sharp 

aches, stiffness, swelling, and limited range of motion. He noted that Dr. Simonsen clearly stated 
4

that appellant immediately developed knee pain as a result from his federal employment duties. 

Counsel also argued that appellant’s claim was credible because his specific injuries could have 

been caused by landing awkwardly after exiting a high-seated vehicle such as the mail truck. He

contended that it would be reasonable for OWCP to accept such as probable, or in the alternative, 

inquire of Dr. Simonsen directly as to his specific view on appellant’s injuries and causal 

relationship between his work-related accident and his diagnosed medical condition. Counsel also 

submitted new medical evidence which he contended was firmly supportive of appellant’s claim 

as causally related to the September 17, 2016 employment incident. He requested that OWCP 

vacate its decision and award wage loss and other compensation.

In a February 24, 2017 report, Dr. Simonsen stated that appellant was injured while 

working for the employing establishment on September 17, 2016. He stated that appellant 

apparently incurred his injury with a twisting knee motion and felt pain in the posterolateral aspect 

of his left knee. Dr. Simonsen summarized his treatment of appellant. He noted that appellant 

was initially seen by his physician assistant, Bonnie Greene, who noted pain over appellant’s 

lateral collateral ligament complex, but no instability, no fractures on plain x-ray, and patellar tilt. 

An MRI scan was obtained which showed a lateral collateral ligament complex tear. Dr. Simonsen 

noted that he first saw appellant on November 4, 2016 and that, at this time, appellant’s left knee 

was consistent with his lateral collateral ligament complex tear. He opined that this was not a new 

injury, but an exacerbation of an injury that occurred to appellant’s left knee on July 23, 2014 

when he slipped getting into a mail truck while delivering mail. Dr. Simonsen noted that, for his 

prior injury, he saw appellant for the same symptomatology and had an MRI scan done, which 

confirmed a tear of his lateral collateral ligament complex. He noted that appellant had no interval 

injury between his first incident and the September 17, 2016 employment incident. Dr. Simonsen

noted that on appellant’s last examination of January 18, 2017 he continued to have pain in the 

posterolateral corner of his left knee, consistent with a lateral collateral ligament complex tear. He 

noted no laxity, but did note pain with a McMurray’s test and stress with palpitation, and that a 

review of his MRI scan confirmed this diagnosis. Dr. Simonsen indicated that appellant required 

prolonged physical therapy, bracing, and limited work until his symptoms clear. He diagnosed 

recurring sprain of a lateral collateral ligament complex tear of the left knee, work related. 

Dr. Simonsen opined that appellant was, at best, capable of desk work. In a progress note dated 

May 8, 2017, he listed the date of injury as September 17, 2016, and diagnosed work-related left 

injury, tear of lateral collateral ligament complex with persistent pain.

By decision dated September 26, 2017, OWCP determined that the evidence submitted by 

appellant was of insufficient probative value to alter the decision of December 22, 2016. It 

determined that Dr. Simonsen’s letter of February 24, 2017 did not provide a rationalized opinion 

which explained how the work incident of September 17, 2016 contributed to, further aggravated, 

or materially worsened the preexisting left knee condition. OWCP stated that it was noteworthy 

that, upon review of the medical evidence, there were no notable change on the MRI scan reports 

and; therefore, it remained unclear exactly how the employment incident of September 27, 2016 

exacerbated or retore appellant’s lateral collateral ligament. It further noted that Dr. Simonsen did 

not provide an opinion which differentiated the effects and symptoms of the preexisting condition 

and the work incident of September 17, 2016.

LEGAL PRECEDENT

An employee seeking benefits under FECA3 has the burden of proof 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, that an injury was sustained in the performance of duty, as alleged, 

and that any disability and/or specific condition for which compensation is claimed are causally 

related to the employment injury.4 These are the essential elements of each compensation claim

regardless of whether the claim is predicated upon a traumatic injury or an occupational disease.5

To determine whether a federal employee has sustained a traumatic injury in the 

performance of duty, it first must be determined whether the fact of injury has been established. 

There are two components involved in establishing fact of injury. First, the employee must submit 

evidence to establish that he or she actually experienced the employment incident at the time,

place, and in the manner alleged.6 Second, the employee must submit evidence, in the form of 

medical evidence, to establish that the employment incident caused a personal injury.7

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

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

physician must be based on a complete factual and medical background of the clamant, must be 

one of reasonable 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 claimant.8

ANALYSIS

The Board finds that the medical evidence of record is insufficient to establish a left knee 

condition causally related to his accepted employment incident on September 17, 2016. 

Initially, the Board finds that OWCP properly adjudicated appellant’s claim as a claim for 

a new injury rather than a recurrence of his prior claim under OWCP File No. xxxxxx139. A 

recurrence of disability means an inability to work after an employee has returned to work caused 

by a spontaneous change in a medical condition resulting from a previous injury or illness without

by a specific event or incident or series of events or incidents occurring within a single workday or work shift, whereas 

an occupational disease refers to an injury produced by employment factors which occur or are present over a period 

longer than a single workday or work shift. 20 C.F.R. §§ 10.5(q), (ee); Brady L. Fowler, 44 ECAB 343, 351 (1992).

a new or intervening injury.9 Appellant’s prior July 23, 2014 claim was accepted for left knee 

sprain. He returned to work following his July 23, 2014 employment injury on 

November 28, 2014. Appellant alleged that his work activities and, particularly, the activities of 

September 17, 2016 caused a recurrence of his previously accepted injury to his left knee. He then

alleged that new work activities, specifically working on his feet all day casing and delivering 

mail, caused an aggravation of the previously accepted left knee condition. Accordingly, as 

properly determined by OWCP, appellant’s claim is for a new traumatic injury.

10

The reports of appellant’s treating physician, Dr. Simonsen, failed to establish causal 

relationship. In his September 30, 2016 examination note, Dr. Simonsen indicated by check mark 

that appellant left knee sprain and plica syndrome were caused or aggravated by his September 17, 

2016 employment activity. It is well established that a physician’s opinion on causal relationship 

that consists of checking a box marked “yes” to a form question is of diminished probative value.11 

In his February 24, 2017 report, Dr. Simonsen diagnosed lateral collateral ligament complex tear. 

He first opined that this was an exacerbation of appellant’s July 23, 2014 employment injury, 

noting that it had the same symptomatology. However, in a progress note dated May 8, 2017,

Dr. Simonsen listed appellant’s date of injury as September 17, 2016, and diagnosed work-related 

left injury, tear of lateral collateral ligament complex with persistent pain. In this report, he does 

not explain his reasoning as to why he believed that appellant’s diagnosed conditions were caused 

by his federal employment duties on September 17, 2016. A mere conclusory opinion provided 

by a physician without the necessary rationale explaining how and why the incident or work factors 

were sufficient to result in the diagnosed medical condition is insufficient to meet a claimant’s 

burden of proof to establish a claim.12 Therefore, this evidence is insufficient to meet appellant’s 

burden of proof. 

The other medical evidence of record is also insufficient to establish causal relationship. 

Dr. Setton interpreted an x-ray, but did not give an opinion on causal relationship. The Board has 

found that diagnostic studies are of limited probative medical value as they do not specifically 

address whether the diagnosed conditions are attributable to accepted employment factors.13 

Accordingly, Dr. Setton’s report is of limited probative value.14

Furthermore, Dr. Marzec did not address causation in his September 19, 2016 treatment 

note. The Board has held that medical evidence that does not offer any opinion regarding the cause 

of the employee’s condition is of diminished probative value on the issue of causal relationship.15

An award of compensation may not be based on surmise, conjecture, speculation, on 

appellant’s own belief of a causal relationship.16 Appellant’s belief that the duties of his federal 

employment caused his injury, however, sincerely held, do not constitute medical evidence 

sufficient to establish causal relationship.17

The Board thus finds that appellant has not established a left knee condition causally related 

to his September 17, 2016 employment incident.

On appeal counsel contends that the medical evidence establishes that appellant was 

injured on September 17, 2016 while in the performance of his federal employment duties. He 

contends that OWCP unjustifiably denied appellant’s claim by adopting an adversarial posture and 

requiring appellant to establish causal relationship beyond all reasonable doubt. For the reasons 

explained above, appellant has not met his burden of proof.

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 established a left knee condition causally related to 

his accepted September 17, 2016 employment incident.
