Whittaker v. District of Columbia Department of Employment ServicesWhittaker v. District of Columbia Department of Employment Services
As we have had to do from time to time in past cases,
1
we must remand this claim for workers’ compensation to the Department of Employment Services (DOES) because the hearing examiner, in denying petitioner benefits, misapprehended the statutory presumption favoring causation.
See
I. The Proceedings
Petitioner received temporary total disability benefits from the date of his injury, November 1, 1988, until their termination on July 4, 1991. After benefits were terminated, he filed a claim with DOES seeking a retroactive award of temporary total disabili

ty benefits, with interest, beginning with the date of their termination, as well the indefinite continuation of benefits and the resumption of vocational rehabilitation.
2
After an evidentiary hearing on February B, 1992, a hearing examiner denied petitioner’s claim in a Compensation Order dated January 14, 1994. Petitioner applied to the Director of DOES for review, but the Director failed to issue a final decision within forty-five days of the date of the application. The Compensation Order thus became a final decision for purposes of review by this court.
II. The Facts
On November 1,1988, petitioner was stepping across a stack of pallet boards at a job site when his foot became caught in a piece of wire mesh, causing him to fall to the ground with his right leg buckled beneath him. The accident caused tears of the back portions of the medial and lateral menisci of petitioner’s right knee. 3 These tears were superimposed upon pre-existing (though non-symptomatic) degenerative arthritis in petitioner’s right knee. All of the damaged cartilage was successfully removed during two arthroscopic surgeries conducted in 1988 and 1989, but at the same time petitioner’s arthritis grew worse, to a point where the hearing examiner found, and the medical experts for the parties agreed, that petitioner was disabled from his usual employment as a crane operator. The examiner concluded, however, that “even though claimant’s symptoms remain, the superimposition of the effects of the work injury have been alleviated, and claimant’s present medical condition is the result of his degenerative arthritis rather than either the November 1, 1988 work injury or the surgery to correct the effects thereof.” In other words, petitioner had failed to “show that his continuing loss of wages [was] the result of the exacerbation of his pre-existent condition rather than ... a result of the natural progression of the [arthritic] condition” (emphasis in original).
III. Discussion
In order to benefit from the presumption, a claimant needs to make some “initial demonstration” of the employment-connection of the disability_ The initial demonstration consists in providing some evidence of the existence of two “basic facts”: a death or a disability and a work-related event, activity, or requirement which has the potential of resulting in or contributing to the death or disability_ The presumption then operates to establish a causal connection between the disability and the work-related event, activity, or requirement.
Once the presumption is triggered, the burden of production shifts to the employer to set forth “substantial evidence” showing that the death or disability is not work-related.... Absent employer evidence “specific and comprehensive enough to sever the potential connection between a particular injury and a job-related event,” the compensation claim will be deemed to fall within the purview of the statute.

Ferreira, supra
note 1,
At the evidentiary hearing, petitioner submitted the deposition testimony of his treating physician and medical expert, Dr. Michael Cassidy, to support a finding that the torn cartilage in his right knee, conceded to have been caused by the work-related fall, had aggravated a pre-existing arthritic condition in his knee.

In considering this evidence, the hearing examiner acknowledged and applied the well-settled principle that “[t]he aggravation of a pre-existing condition may justify compensation.”
Baker, supra
note 1,
In
Baker,
the petitioner, a charter bus driver, sustained an injury to his lower back when the steering wheel of the bus he was driving locked while he was making a left turn. It was uncontested that this injury arose out of and in the course of the petitioner’s employment as a charter bus driver.
In defending the examiner’s refusal to apply the presumption here, intervenors contend that two types of causation must be distinguished: “causation as it relates to a determination of whether an accidental injury arose out of and in the course of employment” and “causation as it relates to whether a particular medical condition is a result of the compensable work injury.” They argue that the statutory presumption applies only to the former. We find no meaning in that distinction. Under this jurisdiction’s “aggravation rule,” there is no question that “a particular medical condition [that] is a result of the compensable work injury” may itself be compensable and thus covered by the presumption. Where there is a dispute (as here) about whether the disabling aggravated condition — the “medical condition” as in-tervenors put it — is causally related to or “arose out of’ the claimant’s employment, the presumption applies and is triggered if the *847 claimant produces “some evidence” of the two basic facts described in Ferreira.
Our decisions thus require the examiner to view the causal relation between a present disability and a job-related injury through the lens, as it were, of the statutory presumption,
unless
the employer has rebutted the presumption by “evidence ‘specific and comprehensive enough to sever the potential connection’ ” between the two.
Parodi,
Petitioner argues that, as in
Parodi, supra,
remand is unnecessary because this court can conclude as a matter of law that the presumption was unrebutted. But
Parodi
was an exceptional case in which “the employer’s own medical evidence ... not only failed to rebut the presumption but [was] consistent with, if not more favorable to petitioner, than [petitioner’s surgeon’s] letter” establishing a potential causal relationship.
Parodi,
Reversed and remanded.

. An issue still unresolved by the hearing examiner is who bore responsibility for the apparent termination of petitioner’s vocational rehabilitation. Whether that issue needs to be resolved depends on the outcome of the further proceedings we direct on the issue of causation.
. A meniscus is "[a] crescent-shaped structure, especially a crescent-shaped piece of cartilage or gristle upon the end of a bone entering in the formation of a joint; the semilunar cartilage of the knee joint.” 2 J.E. Schmidt, Attorneys’ Dictionary of Medicine M-82 (1992).
. Doctor Cassidy testified that it was a reasonable medical probability that "[t]he arthritis may have been there but he was kind of put over the edge by the falling he took at work, the tearing of cartilage." Under cross-examination, Dr. Cassi-dy further explained:
The problem is that by removing the cartilages [as had been required in subsequent surgery], you remove some of the stability of the knee and some of the shock absorbency of the knee, and frequently when you do that, it will advance the progression of degenerative arthritis, because you have removed some of the stabilization of the knee.
