The global rise in total knee arthroplasty (TKA), driven by an aging population, has led to an increased incidence of periprosthetic fractures (PPFs). Dual implants for distal femur periprosthetic fractures (PDFFs) are a growing area of interest for these challenging fractures with dual plating (DP) and plate-retrograde femoral intramedullary nail (PN) emerging as viable constructs for these injuries. However, dual implants have inherent limitations. Herein we focus on describing a modified PN fixation-retrograde tibial intramedullary nail (RTN) combined with a less invasive stabilization system (LISS) for PDFFs following TKA in elderly patients and providing the technical trick of this modified PN fixation.

Purpose: To identify factors that contribute to the speed of angular correction in skeletally immature patients with genu varum treated with paraphyseal tension band plates, hypothesizing that screw length and divergence, severity of deformity, and underlying pathology influence the rate and speed of genu varum correction.
Methods: Fifty-three patients (38 males, 15 females) undergoing genu varum correction were included; a total of 138 physes (64 distal femur, 74 proximal tibia) were assessed. The median age at surgery was 37.

Objectives: The Femoral Neck System (FNS) is a fixed-angle side plate device approved for use in fixation of femoral neck fractures. The FNS perforates the lateral cortex of the subtrochanteric femur, which may increase the risk of postoperative subtrochanteric fractures compared with the inverted triangle cannulated screw (CS) construct. The purpose of this biomechanical study was to compare forces required to create subtrochanteric fractures in FNS and CS constructs in a synthetic bone biomechanical model.

Purpose: Performing a one-stage periarticular osteotomy in conjunction with total knee arthroplasty (TKA) constitutes a technically complex procedure. In such demanding cases, a personalized approach utilizing patient-specific instrumentation (PSI) may serve as an advantageous option to achieve optimal precision in bone cuts, thereby enhancing both clinical and radiological postoperative outcomes.
Methods: We present a case report of a 22-year-old man with multiple epiphyseal dysplasia (MED) resulting in knee osteoarthritis with complex femoral deformity and restricted (passive at 30-120° and active at 80-120°) range of movement (ROM).

This preclinical ex vivo study was conducted to evaluate the effects of submersion in saline or the Missouri Osteochondral Preservation System (MOPS®) solution during plug reaming on Day-0 viable chondrocyte density (%VCD) of osteochondral allograft (OCA) plugs used for osteochondral allograft transplantation (OCAT). Distal femoral OCAs preserved with MOPS were reamed to create cylindrical "plug" grafts using one of three techniques: submersion in MOPS (SG-MOPS), submersion in saline (SG-Saline), or reamer saturated with MOPS without OCA submersion (SR-MOPS). All plug reaming was performed using standardized instrumentation and technique to harvest 18-mm-diameter plugs.
