The choice of skin closure (staples vs. monofilament sutures vs. barbed sutures/adhesive) is critical for wound healing quality in prosthetic surgery (hip and knee). The combination of barbed sutures (e.g., Stratafix) and skin glue (e.g., Dermabond) is promising (superior cosmetic outcome, no suture removal, antimicrobial barrier) but has been poorly evaluated prospectively and comparatively in orthopaedics, which justifies this study. The primary objective is to compare the wound healing success rate at two weeks postoperatively between the patient groups. The primary outcome measure is successful wound healing, defined as the absence of wound complications (wound dehiscence, seroma, hematoma, early postoperative infection) during the first two weeks
