Appeal from the Judgment Entered December 21, 2023 In the Court of Common Pleas of Philadelphia County Civil Division at No(s): 180801939

BEFORE: LAZARUS, P.J., McLAUGHLIN, J., and SULLIVAN, J.

MEMORANDUM BY SULLIVAN, J.: FILED SEPTEMBER 11, 2026

Dr. Gyi P. Mo (“Mo”) and Clinical Care Associates of the University of

Pennsylvania Health System (“Clinical Care” or collectively, “Appellants”)

appeal from the judgment entered against them and in favor of Diana

Melendez (“Melendez”), in this medical malpractice action. Because

Appellants either failed to preserve their issues for appeal and/or the issues

lack merit, we affirm.

We take the underlying facts and procedural history in this matter from

the trial court’s opinion. See Trial Court Opinion, 10/2/23, at 2-15.

Mo is employed by Clinical Care, a part of the University of Pennsylvania

Health System. Beginning in October 2011 and continuing for several years,

Mo served as Melendez’s primary care physician. As early as February 2012,

Melendez complained to Mo about unexplained back pain that would cease

briefly and then return with increased intensity. Melendez’s clinical findings

were unremarkable except for her reflex scores, which were bilateral 4+ on

both her patella and Achilles reflexes. 4+ is indicative of a serious medical

condition. At trial, Mo claimed the recorded 4+ findings were typos or “click

errors” on his part and Melendez’s reflexes were 2+, a normal finding. Mo did

not recommend any additional testing but suggested Melendez take NSAIDs,

-2- J-A08039-25

stretch, and rest. Mo never tested Melendez’s reflexes again, even though

Melendez complained about increasing back pain, weakness, and leg problems

over the next three years. In March 2014, Mo examined Melendez and found

neurological weakness. At trial, Mo claimed the notation of neurological

weakness was a computer “glitch” (weakness glitch) resulting from a flaw in

a computer program, and he did not find neurological weakness but rather

constitutional weakness. Mo did not refer Melendez to a neurologist.

Melendez’s condition continued to deteriorate, and she began having

serious foot problems. In early 2016, Mo referred Melendez to a podiatrist,

Dr. Albert D’Angelantonio (“D’Angelantonio”).1 Melendez saw D’Angelantonio

in 2016, and he ultimately referred her for a neurology consultation. In

January 2017, Melendez began treatment with neurologist Dr. Sami Khella

(“Khella”). Khella ultimately diagnosed Melendez with spinal dural

arteriovenous (“AV”). This condition is curable if caught early. Here, it was

not caught early and following surgery, Melendez became an incomplete

paraplegic; she is both bowel-dysfunctional and incontinent, cannot walk

without a walker, falls regularly, and cannot do most activities of daily living

without assistance.

____________________________________________

1 Melendez filed the instant action against fourteen medical providers including

D’Angelantonio. The case went to trial solely against Mo and D’Angelantonio. However, the jury found in favor of D’Angelantonio and he is not a party to this appeal.

-3- J-A08039-25

At trial, of import to the instant appeal, along with her own testimony,

Melendez presented the expert testimony of Dr. Paul Genecin (“Genecin”), a

board-certified internal medicine specialist. In sum, Genecin testified that,

beginning in 2012, Mo breached the standard of care by not referring Melendez

to a neurologist, not referring her for an MRI, and not repeating the reflex

testing after Melendez showed abnormal results. Notably, Melendez’s counsel

did not ask him whether his opinions were given with “a reasonable degree of

medical certainty.”

Melendez also presented testimony from Dr. Carolyn Brockington

(“Brockington”), a vascular neurologist, and Dr. Ross Noble (“Noble”), who is

board certified in physical medicine, rehabilitation, and electrodiagnostic

medicine. Both testified to Melendez’s current medical condition and the

difference early diagnosis would have made and excluded other possible

causes than AV for the symptoms Melendez displayed. Noble explained how

Melendez’s current physical problems impact her daily life and about the on-

going care she will need in the future; he also testified Melendez is

permanently disabled.

Whitney Jackson, a records manager at Penn Medicine, testified

Melendez had been employed by the Hospital of the University of Pennsylvania

(“HUP”), which terminated her employment because her medical problems

rendered her permanently disabled.

-4- J-A08039-25

Melendez also presented two expert witnesses regarding damages,

Nadine Taniguchi (“Taniguchi”), a nurse life-care planner and David Hopkins

(“Hopkins”), an expert in economic forecasting.

In his defense case, Mo presented expert medical testimony from Dr.

Charles Christopher Smith (“Smith”), an internal medicine specialist, and Dr.

Phillip Dickey (“Dickey”), a neurosurgeon. Both experts disputed Melendez’s

experts’ testimony that there was a breach of the standard of care, and

disputed whether the symptoms Melendez complained to Mo were indicative

of AV, and when Melendez developed AV. Mo’s counsel elected not to call any

previously identified expert witnesses regarding damages, instead relying on

their cross-examination of Melendez’s experts.

The jury found in favor of Melendez but determined she was 6%

contributorily negligent. Its award to Melendez, taking into account the 6%

reduction, was $799,000 for past and future non-economic loss,

$9,321,666.98 for future economic loss, $1,156,811 for past and future lost

earnings, and $7,207,915.30 for future medical expenses. Subsequently, Mo

filed two motions for judgment notwithstanding the verdict (“JNOV”), three

motions for JNOV and/or a new trial, thirteen motions for a new trial, a motion

for remittitur, and a motion for a hearing on reduction of future medical

-5- J-A08039-25

expenses to present value.2 See Trial Court Opinion, 10/2/23, at 16.

Melendez also filed post-trial motions which are not the subject to the instant

appeal. The trial court issued a seventy-five-page opinion finding the majority

of Mo’s claims waived. The instant appeal followed. Mo filed a timely Pa.R.A.P.
