JIA is one of the most common rheumatologic conditions of childhood. Establishing the diagnosis can be challenging in very young children, particularly when clinical presentation is atypical and serology is negative. Surgical intervention may be warranted in the appropriately selected patient with JIA.
Intra-articular injections prior to total hip arthroplasty (THA) have been associated with postoperative infections. The purpose of this study was to determine whether a temporal relationship exists between hip injections prior to THA and infection. Specifically, we asked (1) Do patients who receive hip injections within 3 months of THA have a higher incidence of prosthetic joint infections (PJIs) or surgical site infections (SSIs)? and (2) Do these patients incur higher 90-day costs? Patients with hip injections prior to THA were identified using a national database from 2010 to 2019. Three laterality-specific groups (injection 0 to 3 months, 3 to 6 months, and 6 to 12 months prior to THA)were compared with a matched cohort without prior injection (n=277,841). Primary outcomes included PJIs, SSIs, and costs. Patients who had injections within 3 months of THA had a higher incidence of PJIs at 90 days (5.1% vs 1.6%, P <.01) and 1 year (6.8% vs 2.1%, P <.01), when compared with the matched cohort. They also had a higher incidence of SSIs at 90 days (2.8% vs 1.2%, P <.01) and 1 year (3.7% vs 1.7%, P <.01). Mean costs were 13.7% higher in this injection cohort. Patients who had injections between 3 and 6 months prior to THA had higher incidence and odds of postoperative PJIs at 90 days (2.6% vs 1.6%, P <.04), whereas those with injections beyond 6 months had no differences in PJIs ( P ≥.46). Patients who receive hip injections within 3 months of undergoing primary THA are at increased risk for postoperative PJIs, SSIs, and higher costs. This study reaffirms guidelines for when to perform THAs in these populations. [ Orthopedics . 2023;46(1):19–26.]
Various assessment tools are often used to predict perioperative morbidity among patients older than 75 years who undergo total joint arthroplasty. Yet, few studies describe the use of phenotypic frailty as a predictor for outcomes. The goal of this study was to assess phenotypic frailty with the Sinai Abbreviated Geriatric Evaluation (SAGE) and compare its utility with established assessment tools used in practice. We specifically asked: (1) Can SAGE predict 30-day outcomes, including postoperative delirium? (2) Can SAGE determine the risk of prolonged hospital length of stay? (3) Is SAGE predictive for 30-day readmissions? (4) Can SAGE determine the risk of discharge to a specialized facility? Patients undergoing total hip arthroplasty and total knee arthroplasty were evaluated with the American Association of Anesthesiologists Physical Status (ASA), Charlson Comorbidity Index (CCI), 5-point Modified Frailty Score (5-FS), and SAGE. Assessment scores were determined for each patient, and every incremental change in score was used to predict the likelihood of perioperative complications. A receiver operating characteristic analysis was also performed to calculate testing sensitivity for each assessment tool. The SAGE scores were more likely to predict 30-day complications (odds ratio [95 CI], 2.21 [1.32–3.70]), postoperative delirium (6.40 [1.78–23.03]), and length of stay greater than 2 days (3.90 [1.00–15.7]) compared with ASA, CCI, and 5-FS values. The SAGE scores were not predictive of readmission (1.77 [0.66–4.72]) or discharge to a specialized facility (1.48 [0.80–2.75]). The SAGE score was a more sensitive predictor (area under the curve, 0.700) for perioperative morbidity compared with ASA (0.638), CCI (0.662), and 5-FS (0.644) values. Therefore, SAGE scores can reliably assess risk of perioperative morbidity and may have better clinical utility than ASA, CCI, and 5-FS values for patients undergoing total joint arthroplasty.

Case: A 56-year-old woman underwent a left total hip arthroplasty (THA) after developing avascular necrosis after chemotherapeutic treatment of breast cancer. She presented approximately 2 years after index THA with left groin pain and complaints of instability. Imaging revealed pseudodislocation of the ceramic femoral head with erosion through the acetabular component. Intraoperative evaluation revealed a dissociated polyethylene liner, damaged acetabular locking mechanism, metallosis, and well-fixed and aligned components. Treatment consisted of component retention, bone grafting, and dual-mobility liner cementation into the acetabular component.

The use of the distal femoral replacement (DFR) has grown in recent years. Historically, this procedure was reserved for malignancy and complex revision cases with relative success. In recent years, complex reconstruction cases have had relative success. DFR has been associated with a range of complications including anterior knee pain, patellar instability, limitations in knee motion, and rotational instability that are sequelae of altered patello-femoral mechanics. Thus, subsequent dysfunction may require revision. To our knowledge, no surgical technique to correct DFR patello-femoral maltracking has been demonstrated in current literature. We present a surgical technique for DFR patello-femoral maltracking corrected surgically with femoral component revision and femoral stem retention.
Introduction: Morbid obesity is a known risk-factor for increased complications following total hip arthroplasty (THA). Thus, many orthopaedic surgeons recommend bariatric surgery (BS). However, there is no consensus on the type (commonly either a Roux-en-Y gastric bypass [RYGB] or sleeve gastrectomy [SG]) and timing of BS prior to THA. Therefore, the purpose of this study is to compare BS recipients prior to THA to assess differences in 90-day to 2-year medical/surgical complications as well as revisions for: (1) type of BS (RYGB and SG); and (2) timing of BS. Additionally, we aim to assess risk factors for postoperative prosthetic joint infections (PJIs), dislocations, and revisions. Methods: We queried a national, all-payer database to identify patients undergoing primary THA from January 2010 to October 2020 ( n = 715,100). Patients were then divided into 6 cohorts: 2 cohorts without history of BS (body mass index [BMI] kg/m2 20–35 [ n = 59,995]) and BMI > 40 [ n = 36,799]); 2 cohorts with previous RYGB ( n = 1278) or SG ( n = 1051); and 2 cohorts that underwent BS either 6–12 months ( n = 412) and >12 months ( n = 1655) prior to the THA. Bivariate chi-square analyses of medical and surgical outcomes at 90 days–2 years were conducted. Multivariate logistic regressions identified independent risk factors for PJIs, dislocations, and revisions. Results: At 90 days–2 years, no differences in postoperative medical/surgical complications or revisions were seen among timing or type of BS. The BMI > 40 kg/m2 cohort had the highest complication profile among all other cohorts. Timing and type of BS has similar odds of PJIs, dislocations, and revisions. Conclusions: Patients undergoing RYGB or SG 6–12 months and >1 year prior to THA showed similar complications profiles. These results suggest, bariatric patients do not need to wait 1 year before undergoing a THA.
