DECISION AND ORDER

Before:

PATRICIA H. FITZGERALD, Deputy Chief Judge

JANICE B. ASKIN, Judge

JAMES D. McGINLEY, Alternate Judge

JURISDICTION

On November 10, 2022 appellant filed a timely appeal from an October 21, 2022 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.2

1

5 U.S.C. § 8101 et seq.

2 The Board notes that,following the October 21, 2022 decision, OWCP received additional evidence. However, 

the Board’s Rules of Procedure provides: “The Board’s review of a case is limited to the evidence in the case record 

that was before OWCP at the time of its final decision. Evidence not before OWCP will not be considered by the 

Board for the first time on appeal.” 20 C.F.R. § 501.2(c)(1). Thus, the Board is precluded from reviewing this 

additional evidence for the first time on appeal. Id.

ISSUE

The issue is whether appellant has met his burden of proof to expand the acceptance of his 

claim to include an additional condition causally related to his accepted June 6, 1978 employment 

injury.

FACTUAL HISTORY

This case has previously been before the Board.3 The facts and circumstances as presented 

in the Board’s prior decisions are incorporated herein by reference. The relevant facts are as 

follows.

On June 6, 1978 appellant, then a 37-year-old letter carrier, filed a claim for traumatic 

injury (Form CA-1) alleging that he sustained a left knee injury on that day when his knee struck

a bolt head that protruded from a dash panel in the performance of duty. OWCP accepted the 

claim for left knee meniscus derangement and left leg traumatic arthropathy. On January 13, 1979 

appellant underwent OWCP-authorized left knee surgery which included a total medial 

meniscectomy. He retired from federal employment on November 2, 2002. OWCP subsequently 

expanded acceptance of the claim to include bilateral meniscus derangement, bilateral traumatic 

arthropathy of the lower legs, and right knee internal derangement, open wound of scalp without 

complications, left, and unspecified angina pectoris.4 

By letters dated August 11 and September 4, 2019, appellant requested that his claim be 

expanded to include additional conditions. He indicated that on August 10, 2019 his left knee 

buckled while he was using his table saw. This caused appellant to fall forward and lose grip on 

the wood board he was cutting, which then caused the wood board to strike his left hand. He stated 

that he sustained a fracture and a laceration of the index and middle fingers of his left hand, and 

had four sutures placed in his left index finger.

In an August 11, 2019 emergency room report, Dr. Joseph A. Betcher, a Board-certified 

emergency medicine physician, noted the history of the August 10, 2019 incident and that he had 

sutured appellant’s left-hand laceration. He provided impressions of laceration of left index finger 

and fracture of phalanx of left index finger. An August 11, 2019 x-ray of appellant’s left hand 

indicated a comminuted fracture through the base of the proximal phalanx of the second digit.

3 Docket No. 20-0968 (issued August 17, 2021); Docket No. 16-1477 (issued December 16, 2016); Docket No. 

14-1647 (issued September 18, 2014); Docket No. 14-374 (issued May28, 2014); Docket No. 13-2135 (issued April3, 

2014); Docket No. 13-767 (issued July 8, 2013).

4 Appellant has a prior claim assigned OWCP File No. xxxxxx938, wherein he alleged that on March 18, 1991 he 

slipped and fell and injured both shoulders while in the performance of duty. OWCP accepted that claim for the 

conditions of bilateral shoulder strains, fractured left humerus, lumbar strain and C6-7 herniated disc. Appellant also 

has a prior claim under OWCP File No. xxxxxx096 concerning a November 21, 2000 traumatic injury claim (Form 

CA-1). He alleged that he slipped on snow and ice while in the performance of duty. OWCP accepted that claim for 

aggravation of right shoulder osteoarthritis, lumbar sprain and displacement of cervical intervertebral disc without 

myelopathy. Appellant has a separate prior claim under OWCP File No. xxxxxx468 alleging carpal tunnel syndrome 

and ulnar nerve damage due to factors of his federal employment as of December 22, 2015. OWCP has

administratively combined appellant’s claims, with OWCP File No. xxxxxx096 serving as the master file. 
3

In an October 3, 2019 report, Dr. Ryan P. Ter Louw, a plastic and reconstructive surgery 

specialist, noted the history of injury and that appellant sustained laceration to left index and 

middle fingers. He also noted that the x-ray showed a phalanx fracture. Dr. Louw diagnosed 

de Quervain’s tenosynovitis, bilateral carpal tunnel syndrome, laceration of extensor muscle, 

fascia and tendon of right index finger at forearm level, displaced fracture of proximal phalanx of 

unspecified finger, left index and middle finger laceration from table saw injury and central slip 

injury to the left index finger. He recommended repeat x-ray and hand therapy.

In a December 12, 2019 development letter, OWCP informed appellant of the deficiencies 

of his claim for expansion. It advised him of the type of medical evidence necessary and provided 

a questionnaire for his completion. Appellant was afforded 30 days to respond.

In a December 17, 2019 statement, appellant related that his knees occasionally buckled 

and that he had fallen several times since 1978. He asserted that, if a member is weakened by an 

employable injury and later contributes to a fall or other injury, the test of whether it would be 

considered consequential was if the medical complications directly flow or are a natural 

consequence of the injury. Photographs of appellant’s left hand were enclosed. 

By decision dated March 2, 2020, OWCP denied appellant’s claim for expansion finding 

that he had not met his burden of proof to establish that he sustained an additional condition due 

to his accepted work-related conditions. It found that the factual and medical evidence of record 

was insufficient to explain how the left-hand injury was causally related to his accepted June 6, 

1978 employment conditions. 

On March 10, 2020 appellant requested reconsideration. In a statement dated March 5, 

2020, he asserted that he was not claiming a recurrence of his knee conditions; rather, he was 

claiming a consequential injury to his left hand when his left knee buckled on August 10, 2019 

which caused him to lose control of the plywood he was cutting. Appellant quoted the FECA 

procedural manual for a definition of a consequential injury. In a March 9, 2020 statement, he 

explained that plywood he was holding kicked back and struck his left hand within a fraction of a 

second of his left knee buckling. Appellant provided an explanation of a table saw kick back and 

his calculation of the speed of the kick back. He stated that he had no time to react, and that he 

fell forward onto the surface of the table and running saw blade when his left knee buckled. 

Appellant noted the resulting injury to his left hand and the medical treatment he had undergone. 

A video of the table saw kick back was also submitted.

By decision dated March 17, 2020, OWCP denied appellant’s request for reconsideration 

of the merits of his claim, pursuant to 5 U.S.C. § 8128(a). 

On March 30, 2020 appellant filed an appeal to the Board and, by decision dated 

August 17, 2021,

5

the Board affirmed OWCP’s March 2 and 17, 2020 decisions. 

On September 13, 2021 appellant requested reconsideration. In letters dated September 2

and November 2, 6, 8 and 15, 2021, he continued to assert that the acceptance of his claim should 

be expanded and he cited cases from the FECA procedural manual regarding consequential injury. 

5

Supra note 3.
4

In his November 15, 2021 letter, appellant noted that his August 10, 2019 consequential hand 

injury was adjudicated as a recurrence of the June 6, 1987 compensable left knee injury and 

asserted that this was error on the part of OWCP as he did not file a recurrence claim regarding his 

left lower extremity. 

By decision dated January 31, 2022, OWCP denied modification. 

On March 28 and August 4, 2022 appellant requested reconsideration. In a February 7, 

2022 statement, he provided a definition of consequential injury and stated that he had

compensable weakened knees, he fell at home because his weakened left knee buckled, injuring 

his left hand. Appellant stated that OWCP’s January 31, 2022 decision did not explain why his 

claim was denied for a consequential injury as he provided a detailed mechanism of injury, had

visible injuries, and a left-hand condition had been diagnosed by a physician. He indicated that he 

had provided medical reports from his initial emergency room visit from Dr. Betcher and reports 

from Dr. Ter Louw. In a March 22, 2022 statement, appellant requested that OWCP review all 

additional evidence submitted. In a September 6, 2022 statement, he asserted that he had 

submitted a timely request for reconsideration. 

Additional medical evidence received included March 11, 2020 and August 3, 2022 

diagnostic x-ray reports of appellant’s knees. The March 11, 2020 x-rays revealed moderate-tomoderately severe arthritis of the knees. The August 3, 2022 x-rays related an impression of no 

evidence of fracture or dislocation, mild bilateral osteoarthritis, left greater than right. 

In a March 11, 2020 report, Dr. Brian S. Hood, an osteopath specializing in sports 

medicine, noted appellant’s history of injury and his medical course. Appellant reported that he 

had experienced knee buckling and falling because of pain in both lower extremities. He also 

reported that pain was worse in the right knee than the left knee, but the left knee gave out more 

often than the right knee. Dr. Hood diagnosed bilateral primary osteoarthritis of the knees, noting 

that x-rays showed moderate-to-severe osteoarthritis in both knees with essentially bone-on-bone 

apposition of the medial compartment of the left knee. In an August 3, 2022 report, he provided 

examination findings of appellant’s knees and indicated that x-rays taken revealed essentially 

bone-on-bone apposition left knee with almost bone-on-bone apposition to the right knee. 

Dr. Hood diagnosed bilateral primary osteoarthritis of the knees and discussed treatment options. 

By decision dated October 21, 2022, OWCP denied modification of its January 31, 2022 

decision. 

LEGAL PRECEDENT

When an injury arises in the course of employment, every natural consequence that flows 

from that injury likewise arises out of the employment, unless it is the result of an independent 

intervening cause attributable to the claimant’s own intentional misconduct.6 Thus, a subsequent

injury, be it an aggravation of the original injury or a new and distinct injury, is compensable if it 

is the direct and natural result of a compensable primary injury.7

The claimant bears the burden of proof to establish a claim for a consequential injury.8 As 

part of this burden, the claimant must present rationalized medical opinion evidence, based on a 

complete factual and medical background, establishing causal relationship. The opinion must be 

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

nature of the relationship of the diagnosed condition and the specific employment factors or 

employment injury.9 The weight of 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

ANALYSIS

The Board finds that appellant has not met his burden of proof to expand acceptance of his 

claim to include an additional condition as a consequence of his accepted June 6, 1978 

employment injury.

The Board notes that, with respect to appellant’s burden of proof to establish an additional 

condition due to his accepted June 6, 1978 employment injury, it is unnecessary to consider the 

evidence that he submitted prior to the issuance of OWCP’s March 17, 2020 decision, which was 

considered by the Board in its August 17, 2021 decision. Findings made in prior Board decisions 

are res judicata absent further merit review by OWCP under section 8128 of FECA.11

Following the Board’s August 17, 2021 decision, appellant submitted medical evidence 

from Dr. Hood. Dr. Hood did not address how appellant’s accepted bilateral knee conditions 

would have caused his knees to buckle, and then cause the consequential injury to his left hand. 

While appellant has continually alleged that he has identified the mechanism of injury, and his 

physicians have provided diagnoses regarding his bilateral knee and hand conditions, his 

physicians have not explained how the accepted knee conditions caused his knee to buckle on

August 10, 2019. The Board has held that, to establish a consequential injury, the medical 

evidence of record must explain how the accepted injury caused the consequential condition and 

injury.

12

 The medical evidence of record does not establish that appellant’s knee buckled on 

August 10, 2019 due to his June 6, 1978 injury. In his reports, Dr. Hood diagnosed bilateral knee 

osteoarthritis. The Board notes that bilateral knee osteoarthritis is not an accepted condition. 

Without explaining physiologically how the accepted employment injury caused, contributed to,

or aggravated the additional diagnosed conditions, Dr. Hood’s opinion is of limited probative value 

and insufficient to establish the claim.13

OWCP also received x-ray reports. However, diagnostic studies, standing alone lack 

probative value on causal relationship as they do not address whether employment factors caused 

the diagnosed condition.14

As the medical evidence of record is insufficient to establish causal relationship between 

an additional condition and the accepted June 6, 1978 employment injury, the Board finds that 

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 met his burden of proof to expand the acceptance of 

his claim to include an additional condition as a consequence of his accepted June 6, 1978 

employment injury.
