Eligibility

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.

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 Exclusion Criteria:

• 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
