Eligibility
Key inclusion criteria
- is at least 22 years of age on the date of informed consent.

- can independently provide informed consent.

- requires and is scheduled to undergo a simultaneous, bilateral, primary TKA.

- is willing and physically capable of undergoing a simultaneous, bilateral, primary TKA
with or without replacement of the patella.

- is willing and able to return for all scheduled study visits.
Minimum age
22 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- is pregnant or lactating.

- has signs of an infection in the area of either knee or has signs of a systemic
infection at the time of surgery.

- is a chronic opioid user, defined per the CDC guidelines as opioid use for >3 months,
at the time of enrollment.

- has a current diagnosis of lymphedema in either leg.

- has signs, symptoms, or a current diagnosis of venous insufficiency in either leg, as
determined by the investigator's review of the subject's medical history.

- has a history of clotting disorder or prior history of deep vein thrombosis

- will undergo a unilateral TKA.

- will undergo a staged, bilateral TKA.

- has had previous knee replacement surgery.

- has received a corticosteroid injection into either knee within 30 days of surgery.

- undergoes a simultaneous, bilateral TKA with a planned different incision type on each
knee (eg, midline incision vs. medial parapatellar incision).

- has known sensitivity to the study product components (drape and/or dressing materials
in direct contact with the closed incision or skin).

- has known sensitivity to silver.

- is enrolled in another interventional clinical study.

- has skin cancer localized at or in proximity to the incision site.

- does not have access to an electronic device (smartphone, iPad, or computer) on a
daily basis to complete online assessments.

- has condition(s) that, in the opinion of the investigator, cause the subject to be an
overall health risk that is unsuitable for the surgery.

- has condition(s) that, in the opinion of the investigator, will impact study endpoints
(eg, hemophilia or autoimmune disorders) or the ability to comply with study
procedures.

Intra-Op

- does not receive a "total" knee replacement for first knee. For example, a partial or
uni-compartmental knee replacement is performed

- has a surgical incision that would preclude placement of either dressing onto the knee

- has a TKA resulting in a muscle flap
