Research Article: Risk Factors and Dynamic Nomogram Development for Surgical Site Infection Following Open Wedge High Tibial Osteotomy for Varus Knee Osteoarthritis: A Retrospective Cohort Study
Abstract:
Open wedge high tibial osteotomy (OWHTO) is a well-established treatment for medial compartment knee osteoarthritis (KOA) with varus deformity. However, the patient’s prognosis may be severely compromised by surgical site infection (SSI). According to the guidelines, SSI is defined as an infection that affects the incision or deep tissues at the surgical site, usually occurring within days of surgery and up to one year after implantation., SSI is uncommon, with an incidence of .%- .%,– but when it does occur, it may lead to catastrophic medical consequences, such as incision nonhealing, secondary surgery, and even sepsis and death. Furthermore, SSI has been reported to increase patient average hospital stays by to days, contributing approximately $. billion to $ billion in annual US healthcare expenditures. Considering that the population of patients who received OWHTO is growing as the prevalence of KOA increases globally, finding appropriate methods to effectively prevent SSI after OWHTO is a challenge that surgeons must address.
