ISSUE

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

causally related to the accepted August 29, 2016 employment incident.

FACTUAL HISTORY

On August 30, 2016 appellant, then a-59-year-old general expeditor, filed a traumatic 

injury claim (Form CA-1) alleging that on August 29, 2016 she injured her left knee when lifting 

a dock door while in the performance of duty. She stopped work that same day. 

Appellant was initially treated in the hospital emergency department on August 29, 2016.

Hospital discharge instructions indicated that she was seen by Dr. Robert A. Spence, Boardcertified in emergency medicine, for knee pain and a possible meniscus injury.

In a September 15, 2016 development letter, OWCP informed appellant that the evidence 

submitted was insufficient to establish her claim. It advised her of the type of factual and medical 

evidence necessary to establish her claim and provided a factual questionnaire for her completion. 

OWCP afforded appellant 30 days to provide the necessary evidence.

In an August 29, 2016 medical report, Dr. Spence noted that appellant had arrived by 

ambulance on that day with complaint of left knee pain. Appellant indicated that she felt a pop in 

her left knee when lifting a heavy door at work. Physical examination revealed lateral tenderness 

and pain with pivot shift tests. Dr. Spence indicated that the x-rays demonstrated degenerative 

joint disease. He diagnosed left knee pain and a possible meniscus tear. In a medical note of even 

date, Dr. Spence detailed appellant’s medication history.

An August 29, 2016 left knee x-ray report revealed degenerative change and effusion, but 

no evidence for fracture.

In a September 14, 2016 medical report, Dr. Martin Luber, a Board-certified orthopedic 

surgeon, noted that on August 29, 2016 appellant was lifting a heavy door at work by pushing the 

door from below, while using her legs to be the primary power generator, when she felt a pop and 

acute onset of left knee pain. He indicated that she immediately developed a burning sensation 

and a large intra-articular effusion. Dr. Luber noted that appellant was out of work since that injury 

and relying on anti-inflammatories and crutches for ambulation. On physical examination he noted 

valgus malalignment on both knees, coarse retropatellar crepitance on the left, moderate lateral 

joint line pain on the left, and coarse right patella crepitance on the right. Dr. Luber indicated that 

the radiographic studies showed endstage bicompartmental osteoarthropathy bilaterally, finding 

that the total femoral joint was worse in the left knee. He diagnosed an acute onset of left knee 

pain and an exacerbation of the underlying osteoarthropathy. Dr. Luber recommended a course of 

conservative care and noted that it was unlikely that arthroscopic surgery for meniscus pathology 

was warranted based on the degree of appellant’s osteoarthropathy. In a prescription slip of even 

date, he diagnosed left knee osteoarthritis. In a work restriction note of even date, Dr. Luber

advised that appellant remain off work until a follow-up appointment in four weeks.
3

Appellant also submitted a continuation of pay nurse report dated September 15, 2016, 

indicating that she remained off work due to a left knee injury.

OWCP received physical therapy notes dated September 20 through October 7, 2016. 

In an October 12, 2016 work restrictions note, Michael Cavanagh, a certified physician 

assistant, advised that appellant remain off work until her next follow-up appointment.

By decision dated October 25, 2016, OWCP denied appellant’s traumatic injury claim, 

finding that the medical evidence of record was insufficient to establish that her diagnosed medical 

condition was causally related to the accepted August 29, 2016 employment incident.

In an October 12, 2016 medical report, Mr. Cavanagh noted that appellant had welldocumented endstage osteoarthritis and underwent injections in both knees in late 

September 2016. He diagnosed symptomatic lateral compartment osteoarthritis of bilateral knees. 

In a duty status report (Form CA-17) of even date, an unidentifiable healthcare provider held 

appellant off work until her follow-up appointment on November 9, 2016. 

On October 28, 2016 appellant filed a claim for compensation (Form CA-7) for disability 

from work for the period October 14 through 28, 2016. 

In a November 9, 2016 medical report, Mr. Cavanagh noted that appellant’s symptoms 

continued. He indicated that appellant developed intermittent wear and tear on her left knee over 

her 40 years of employment. Mr. Cavanagh diagnosed advanced left knee osteoarthritis and posttraumatic exacerbation of the preexisting condition. 

In a November 18, 2016 work restrictions note, Mr. Cavanagh provided restrictions, 

including no prolonged standing, sitting, or walking. 

On November 23, 2016 appellant requested a review of the written record before a 

representative of OWCP’s Branch of Hearings and Review. 

In a December 22, 2016 medical report, Mr. Cavanagh observed that appellant had 

exquisite lateral joint line tenderness and mild pain in her left knee. He diagnosed post-traumatic 

exacerbation of the left knee lateral compartment arthritis. 

By decision dated May 1, 2017, an OWCP hearing representative affirmed the October 25, 

2016 decision.

On April 27, 2018 appellant, through counsel, requested reconsideration. 

Appellant resubmitted Mr. Cavanagh’s reports dated October 12 through December 22, 

2016, countersigned by Dr. Luber.

In a January 15, 2017 narrative report, Dr. Justin W. Kung, a Board-certified radiologist, 

reviewed appellant’s September 14, 2016 bilateral knee x-rays. He found that, overall, the x-rays 

revealed severe degenerative changes in the lateral component of both knees. 
4

In an August 2, 2017 medical report, Dr. Jeffrey L. Katzell, an orthopedic surgery 

specialist, indicated that appellant retired from the employing establishment in 2017, after 41 years

of service. He noted that the continuous performance of her work duties, including bending, 

twisting, squatting, and stooping for each delivery, over 2,400 full calendar days, produced 

extensive wear and tear on both knees. Dr. Katzell indicated that appellant currently used a cane 

and still had significant pain while walking on flat surfaces, walking up and down stairs, and 

walking on uneven surfaces. On physical examination he noted bilateral lateral patella 

maltracking, palpable crepitation when grinding with motion, tenderness, and peripheral 

varicosities. Dr. Katzell diagnosed bilateral knee degenerative arthritis and permanent aggravation 

of the preexisting left knee degenerative arthritis secondary to the accepted August 29, 2016 

employment incident. He explained that arthritis was a loss of articular cartilage surface which 

was impact loading resulting from repeated local stresses that caused and accelerated the 

progression of arthritis through a process of chronic inflammation. Dr. Katzell found that for an 

employee like appellant, who could not engage in lifestyle modification because her job required 

her to do such activities every day, the progression of arthritis was accelerated. 

Dr. Katzell opined that the accepted August 29, 2016 employment incident caused an 

exacerbation/acceleration of appellant’s preexisting left knee arthritis. He noted that appellant 

developed marked swelling in her left knee with pain as a result of the accepted August 29, 2016 

employment incident when she injured her left knee while lifting a heavy door. Dr. Katzell 

explained that the fact that she heard a pop in her left knee on August 29, 2016 while lifting the 

heavy door signified an acute and traumatic instance of severe impact loading onto the surface of 

the articular cartilage of the joint. He further opined that such acute events were direct causes of 

articular surface damage, which, by definition, would be an aggravation of the preexisting arthritis. 

Dr. Katzell further explained that “pushing the door from below while using her legs to be the 

primary generator power” was a classic description of an excessive impact loading movement that 

would and did cause further degradation of the articular surface of the weight-bearing joints of the 

lower extremity. He concluded that both appellant’s work activities over a period of time and the 

accepted August 29, 2016 employment incident contributed to her present arthritic condition. 

Dr. Katzell indicated that appellant had 50 percent bilateral knee impairment and that the loss of 

cartilage in both knee joints was irreversible.

By decision dated July 18, 2018, OWCP denied modification of the May 1, 2017 decision. 

On July 11, 2019 appellant, through counsel, requested reconsideration and attached a 

July 10, 2019 narrative report from Dr. Katzell. In an accompanying brief in support of appellant’s 

claim, counsel argued that Dr. Katzell’s July 10, 2019 report would show that, in addition to the 

previously diagnosed aggravation of the preexisting condition, appellant also sustained a lateral 

meniscus tear from the accepted August 29, 2016 employment incident. 

In his July 10, 2019 supplemental medical report, Dr. Katzell indicated that he reviewed 

appellant’s factual and medical history, including Dr. Luber’s medical reports dated from 

September 14 through December 22, 2016, to provide an opinion within a reasonable degree of 

medical certainty. He noted that he agreed with Dr. Luber’s assessment that appellant suffered 

from a work-related exacerbation of her underlying left knee arthritis. Dr. Katzell opined that 

appellant’s description of the mechanism of injury, including pushing a steel door upward while 

using her legs as a power generator, would result in a torn meniscus, which was caused by 
5

significant downward pressure on the knee joint while engaged in a one-time forceful activity. He 

indicated that the immediate “popping” sensation with immediate onset of pain was also a classic 

symptom of a torn meniscus. Dr. Katzell explained that the fact that more than two weeks of ice, 

anti-inflammatories, and crutch assisted ambulation did not result in any significant improvement 

confirmed that there was additional pathology contributing to the medical condition of appellant’s 

left knee. He opined that the “likelihood that the pathology was a torn lateral meniscus” was very 

strong. Dr. Katzell also noted that a meniscus tear was immediately suspected as a possible 

diagnosis after appellant was taken to the emergency room on August 29, 2016. He concluded

that Dr. Luber’s findings in his December 22, 2016 report of appellant’s exquisite lateral joint line 

tenderness further confirmed the diagnosis of a meniscus tear. 

Appellant also submitted a July 1, 2019 statement in support of reconsideration in which 

she reiterated her history of injury while working on August 29, 2016. She explained that, when 

she bent down to lift a steel dock door to an elevated position, she grabbed the handle of the door 

and used her legs to lift the door. When she did this, appellant felt a pop and then immediate pain 

in her left knee, and she could not put a weight on it. She noted that she was immediately taken to 

the emergency room by ambulance and was told that she had a possible meniscus tear in her left 

knee.

By decision dated October 3, 2019, OWCP denied modification of the July 18, 2018

decision. 

LEGAL PRECEDENT

An employee seeking benefits under FECA4 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,5that 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.6 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.7

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

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

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

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

time, place, and in the manner alleged. Second component is whether the employment incident 

caused a personal injury and can be established only by medical evidence.8 

The medical evidence required to establish causal relationship between a claimed specific 

condition and an employment incident is rationalized medical opinion evidence.9 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 specific employment factors 

identified by the employee.10

In a case in which 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 support of her claim, appellant submitted August 2, 2017 and July 10, 2019 reports from

Dr. Katzell addressing causal relationship. In both reports, Dr. Katzell provided a comprehensive 

factual and medical history of her medical conditions and found that the accepted August 29, 2016 

employment incident aggravated her preexisting left knee arthritis. In the August 2, 2017 report,

he explained that pushing the door from below while using her legs to as the primary power 

generator was a classic description of an excessive impact loading movement that would and did 

cause further degradation of the articular surface of the weight bearing joints of the lower 

extremity. Dr. Katzell opined that such acute events were direct causes of articular surface 

damage, which, by definition, would be an aggravation of a preexisting arthritis. Furthermore, in 

his July 10, 2019 report, he opined that the accepted August 29, 2016 employment incident also 

caused a meniscus tear. Dr. Katzell explained that the fact that more than two weeks of ice, antiinflammatories, and crutch assisted ambulation did not result in any significant improvement 

confirmed that there was additional pathology contributing to the medical condition of appellant’s 

left knee. He opined that the “likelihood that the pathology was a torn lateral meniscus” was very 

strong. Dr. Katzell also noted that a meniscus tear was immediately suspected as a possible 

diagnosis when appellant was immediately taken to the emergency room on August 29, 2016. He

concluded that Dr. Luber’s findings in his December 22, 2016 report of appellant’s exquisite 

tenderness and explained that the report further confirmed the diagnosis of a lateral meniscus tear.

It is well established that proceedings under FECA are not adversarial in nature and, while 

appellant has the burden of proof to establish entitlement to compensation, OWCP shares 

responsibility in the development of the evidence.12 It has an obligation to see that justice is done.13

Accordingly, the Board finds that, while Dr. Katzell’s August 2, 2017 and July 10, 2019 

reports are not fully rationalized, they are sufficient to require further development as his opinion 

demonstrates knowledge of appellant’s preexisting left knee condition and explains the 

physiological process by which the accepted August 29, 2016 employment incident could have 

aggravated appellant’s preexisting left knee arthritis and caused a possible meniscus tear.

Dr. Katzell also noted physical findings upon examination and treatment consistent with his noted 

mechanism of injury and provided an opinion citing to the facts of the case. Thus, the Board finds 

that Dr. Katzell’s opinion is sufficient to require further development of the record by OWCP.14

On remand OWCP shall refer appellant to a specialist in the appropriate field of medicine, 

along with the case record and a statement of accepted facts. The referral physician shall be 

instructed to provide a well-rationalized opinion as to whether appellant’s diagnosed left knee 

conditions are causally related to the accepted employment duties, including the incident on 

August 29, 2016 incident. If the physician opines that the diagnosed conditions are not causally 

related, he or she must explain with rationale how or why their opinion differs from that articulated 

by Dr. Katzell. After such further development of the case record as OWCP deems necessary, it 

shall issue a de novo decision. 

CONCLUSION

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