Background: Total knee arthroplasty is a widely endorsed surgical intervention, extensively recognized within the orthopedic field for its efficacy in significantly reducing pain and enhancing overall mobility in patients suffering from advanced stages of osteoarthritis. Despite a general consensus on the core procedural steps, the rapid advancements in implant technology and the nuanced techniques in knee reconstruction have inevitably introduced subtle variations in surgical approaches. These variations often emerge due to individual surgeon preferences, their unique expertise, and comfort levels with specific techniques. Anterior knee pain, however, remains a frequent postoperative complication, likely attributed to the extensive and complex innervation of the patella. To address this challenge, some surgeons have adopted patellar denervation, hypothesizing that by reducing nerve signaling from the patellar region, patients may experience a measurable decrease in pain. Methods: A systematic search was performed to include eight recent level I studies to analyze this issue. Results: Of the eight reviews, there were four strong studies that concluded patellar denervation helps decrease anterior knee pain in the acute period, but this may not last long term. The other four papers did not show a difference in anterior knee pain after denervation. Conclusions: This review synthesizes and critically analyzes the current body of literature, aiming to provide clinicians with evidence-based insights into the potential benefits and limitations of incorporating patellar denervation into their surgical especially during the acute post-operative period.

Background: Advancements in surgical wound management have led to improved healing and reduced complications. Incisional negative pressure wound therapy (iNPWT) is a technique that applies sub-atmospheric pressure to closed surgical wounds, enhancing blood flow, minimizing edema, and promoting tissue repair. Initially developed for chronic wounds, its use has expanded across multiple surgical specialties, including orthopaedic trauma surgery, to reduce complications such as dehiscence, infection, and prolonged healing. While traditional wound care relies on standard closure methods with simple dressings, iNPWT offers additional mechanical support and may lower the risk of deep surgical site infections (SSIs). This review examines the current evidence on iNPWT’s role in preventing SSIs following surgery for lower extremity fractures to guide clinical decision-making and improve patient outcomes. Methods: A systematic search through PubMed and MEDLINE utilizing our inclusion and exclusion criteria yielded seven randomized controlled trials and randomized prospective cohort studies that were subsequently analyzed to determine iNPWT effectiveness. Results: Of the seven studies, five showed a decreased SSI rate compared to standard wound dressing, with the other two exhibiting an increased infection rate. Conclusions: This review critically examines existing literature on iNPWT, analyzing level I and II studies on deep SSI rates in traumatic fractures. The evidence remains inconclusive on whether iNPWT offers a significant advantage over standard wound dressings, highlighting the need for further research to clarify its efficacy and clinical application.
