prevena™ incision management system over primarily closed hip and knee incisions in patients immediately post total hip and knee arthroplasty

Conditions: Linear or Emi-linear Incisions; Total Hip Arthroplasty; Total Knee Arthroplasty

Summary: the intent of this study is to evaluate the prevena ™ 125 unit and dressing system, when applied to either the hip or knee area over a surgical cut for the time you are hospitalized.

willing to wear loose fitting clothing for duration of treatment period 9. subject must be willing to comply with visit schedule for the duration of the study exclusion criteria: 1. positive pregnancy test confirmed by hcg in urine 2. current or past (30 days prior to surgery) within time of screening attempts to become pregnant 3. current local or systemic infection (eg, skin infections, sinus infections, urinary tract infection, sepsis, etc) 4. current or past (14 days prior to surgery) within time of screening topical treatments on operative area (eg, laser hair or tattoo removal, sunless tanning lotions) 5. current or past (14 days prior to surgery) steroid topical therapies on operative area 6. current or past (30 days prior to surgery) use of oral steroids (note: use of non-topical, ophthalmic or aerosol types of steroids (ie, inhaled corticosteroids) are permitted at screening and throughout the clinical trial) 7. current or past (72 hours prior to surgery) within surgery use of antihistamines 8. current or past (30 days prior to surgery) within time of screening use of oral tetracycline or acutanetm or topical tetracycline or acutanetm on the operative area 9. presence of skin lesions or abnormalities on operative area 10. current or past malignancy requiring immunosuppressant therapy or chemotherapy within 5 years within time of screening 11. presence of excessive skin folds on operative area 12. intentional exposure of the operative area to ultraviolet radiation (14 days prior to surgery) within time of screening (ie, sunbathing or tanning bed) 13. presence of sunburned or peeling skin on operative area 14. tattoos on operative area 15. presence of severe, raised scar tissue on operative area which may interfere with pre and post skin evaluation assessments 16. presence of an open wound prior to the index surgical procedure on operative area 17. reported alcohol (≥ 3 drinks per day) or drug abuse within the past 6 months 18. topical hypersensitivity or allergy to any disposable components of the dressing system (eg, silver, polyurethane, polyester, or acrylic adhesive) 19. topical hypersensitivity or allergy towards any medical adhesive 20. current enrollment or past participation in this clinical study or any other study within ≤30 days 21. any systemic or local active dermatological disease that might interfere with the evaluation of the operative area (eg, meleney's ulcer, scleroderma, chronic urticaria, psoriasis, skin cancer, eczema, seborrhea, or malignancy) 22. connective tissue disease or collagen vascular disease (eg, ehlers-danlos syndrome, systemic lupus erythematosus, rheumatoid arthritis) 23. current or history of hematological disorders or conditions (eg, polycythemia vera, thrombocythemia, sickle-cell disease) 24. any subject with conditions which can potentially result in abnormally pigmented skin (eg, melasma, vitiligo, pityriasis versicolor) 25. inability or refusal to wear loose fitting clothing for the duration of the treatment period 26. subjects in whom orthopaedic reconstruction is required in addition to total hip or knee arthroplasty 27. subjects who are having the total hip or knee arthroplasty as a result of acute orthopaedic trauma 28. subjects who have incurred acute orthopaedic trauma (ie, hip fracture) recently or at any time 29. subjects who have either acute or chronic open/active wounds present (including biopsies, ulcerations, etc) 30. subjects in whom the index procedure is a revision of a total hip or knee arthroplasty 31. subjects in whom the primary or partial total hip or knee arthroplasty would also be performed on the contra lateral knee or hip at the same time
