This study will enroll patients who will be receiving primary total knee replacements. Subjects will be randomized into two groups: Betadine surgical scrub preparation and ChloraPrep preparation prior to total knee replacements.

Study hypothesis: When used as a surgical scrub preparation prior to primary total knee arthroplasties, ChloraPrep (2% chlorhexadine gluconate and 70% isopropyl alcohol) is superior to Betadine (10% povidone iodine) in reducing incision site bacterial colony counts.
Swabs will be taken over the operative knee by study personnel for a bacterial colony count immediately before surgical site preparation is started, after the surgery prep is complete, and 24 hours post surgery prep. Swabs will be sent to the lab for quantitative colony counts and all 3 measurements will be compared and analyzed.

Estimate

Drug Swab area with Betadine

A swab will be taken over the operative knee before surgical site preparation is started, after preparation has taken place, and 24 hours post-surgery.

  • Other names: Povidone Iodine

Drug Swab area with ChloraPrep

A swab will be taken over the operative knee before surgical site preparation is started, after preparation has taken place, and 24 hours post-surgery.

  • Other names: Chlorhexadine Gluconate

Arm 1 Active Comparator

Subjects randomized to Arm 1 will receive Betadine surgical scrub at the time of primary total knee arthroplasty.

Arm 2 Active Comparator

Subjects in Arm 2 will receive ChloraPrep surgical scrub prior to elective primary total knee arthroplasty.
