Wound complications after total knee arthroplasty (TKA) can arise from many patient-specific factors, such as vascular or immune-related medical conditions, obesity, and smoking, among others. The development of early wound complications can lead to increased length of hospital stay and more serious complications, including deep infection and major subsequent surgery. However, there are modifiable variables that could affect the risk of getting wound complications, such as the closure technique. This study aims to analyze the difference in rates of wound complications using two different closure techniques in primary TKA.

Inclusion Criteria:

• Patients older than 18 years old that will undergo primary TKA with a midline approach

Exclusion Criteria:

• Previous knee arthroplasty surgeries or midline scars
• TKA secondary to oncologic or traumatic etiologies
• BMI ≥ 40
• uncontrolled diabetes (measured by a Hgb A1c above 8)
• reported allergy to skin adhesive
• immunodeficiencies
• bleeding disorders
• anticoagulation other than ASA
