NeoPatch Used as Adjunct in Foot and Ankle Tendon Surgery

This study is a prospective, single center, postmarket study to evaluate the safety and
effectiveness of NeoPatch used as a tissue cover for chronically injured tendons requiring
surgical revision. NeoPatch is a tissue covering derived from terminally sterilized,
dehydrated human placental membrane tissue comprised of both amnion and chorion. Candidates
for this study are patients presenting with chronic tendon pain that are being evaluated for
primary tendon revision surgery following failure of standard of care or immediate need for
surgery, as determined by the investigator. Consented patients will receive NeoPatch as an
adjunct to their foot or ankle tendon revision; NeoPatch will be wrapped around the tendon
immediately prior to closure. The study will be divided into two phases: Screening and
Follow-up. The study will include prospective patient evaluations at scheduled clinic visits
and ultrasound appointments for a maximum of 12 visits over 12 months. Patient history,
medications, self-reported pain, tendon status, and adverse events will be collected on all
patients consented and enrolled into the study.

Inclusion Criteria:

- Chronic tendinopathy requiring surgical revision in the opinion of the Investigator as
defined in Appendix G.

- Intention to schedule surgical revision.

≥ 18 years.

- Free from clinical signs of infection at time of screening and at time of surgical
intervention.

- Target tendon is one of the following: Achilles, Extensor Digitorum Longus, Extensor
Hallucis Brevis, Extensor Hallucis Longus, Flexor Digitorum Longus, Flexor Hallucis
Longus, Tibialis Anterior, Tibialis Posterior, Peroneus Longus, Peroneus Brevis,
Peroneus Tertius.

- Able and willing to provide consent and comply with protocol.

Exclusion Criteria:

- History of surgical intervention involving target tendon.

therapy; stable NSAID doses for mild rheumatoid arthritis permitted.

- Pregnant or breastfeeding or planning on becoming pregnant or unwilling to use
medically acceptable methods of birth control.

- Taking medications considered to be immune system modulators within previous 30 days.

- Patient taking specific Cox-2 inhibitors within previous 30 days.

- Currently being treated with an investigational device or drug (within 3 months prior
to surgery).

product.
