Expanded indications and patient demand have significantly increased the number of TKA performed in young and active patients under age 55. While improved materials have decreased the likelihood of early catastrophic wear, concerns remain with the performance and survivorship of TKA implants in this patient population. Therefore, the purpose this study is to evaluate the clinical outcomes, complications, and implant survivorship of TKAs performed in patients under age 55. We retrospectively reviewed 1194 primary TKA performed for the diagnosis of primary knee osteoarthritis performed at our institution between 2013–2016. There were 291 TKA performed in patients under age 55. Patients were excluded if they had 1) prior history of fracture, 2) renal disease, 3) inflammatory joint disease, and 4) required therapeutic anticoagulation. The primary outcome of interest was rate of revision at 30 days, 1, 2, and 5-year time points. Secondary outcomes included postoperative transfusion rate, calculated blood loss, length of stay(LOS), rate of DVT/PE, readmission and reoperation.Introduction
Materials and Methods
Total hip arthroplasty (THA) is gaining popularity as a treatment for displaced femoral neck fractures (FNF), especially in physiologically younger patients. While elective THA for primary osteoarthritis (OA) has demonstrated low rates of complications and readmissions, the outcomes of THA for FNF are less predictable. Additionally, these THA procedures are equally included in various alternative payment bundles. Therefore, the aim of this study is to assess postoperative complication rates after THA for primary OA compared with FNF. The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database from 2008 to 2016 was queried. Patients were identified using the Current Procedural Terminology (CPT) code for THA (27130) and divided into groups by diagnosis; OA in one group and FNF in another. Univariate statistics were performed. T-test compared continuous variables between groups, and Chi-square test compared categorical variables. Multivariate and propensity matched logistic regression analyses were performed to control for risk factors of interest. The primary outcomes for this study were death or serious morbidity (surgical site infection (SSI), infection, respiratory complication, cardiac complication, sepsis, or blood loss anemia requiring postoperative transfusion). Additional secondary outcomes included the incidence of specific complications, total operative time (time from incision to closure), length of hospital stay and proportion of patients that were discharged home.Introduction
