Comparative finite element analysis between three surgical techniques for the treatment of type VI schatzker tibial plateau fractures.

. Open reduction internal fixation (ORIF) and external fixation are traditional surgical techniques for treating type VI Schatzker tibial plateau fractures. A newly developed technique integrates the intramedullary tibial nail with condylar bolts.

Post-operative periprosthetic femoral fractures in England: Patient profiles and short-term outcomes.

Background And Objective: Post-operative periprosthetic femoral fractures (POPFF) present a growing challenge for healthcare services, but there are limited national data on patient profiles, short-term outcomes, and post-discharge follow-up. We aimed to fill these gaps.

Methods: Using Hospital Episode Statistics (HES), we identified POPFF discharges from hospitals in England for patients aged 18 and above between April 2016 and December 2022.

Comparative Study of Exchange Nailing and Augmentative Plating for Treating Aseptic Nonunion of Femoral Shafts Post Intramedullary Nailing: A Single-Blind, Multicentric Randomized Clinical Trial.

: Aseptic nonunion of femoral shafts after intramedullary nailing (IMN) can be a challenging condition that may lead to long-term disability and the need for multiple surgical procedures. This study compared the clinical and radiological outcomes between exchange nailing and augmentative plating with bone grafting. : In this multicenter, prospective, single-blind, randomized controlled trial, patients with aseptic nonunion of the femoral shaft after IMN were randomly assigned to receive exchange nailing or augmentative plating.

Application of neuromuscular electrical stimulation during immobilization of extremities for musculoskeletal conditions: A scoping review.

Background: Neuromuscular electrical stimulation (NMES) is effective at improving recovery after periods of disuse. It is unclear if NMES can be applied during periods of immobilization for musculoskeletal conditions to mitigate resulting impairments from disuse. The aim of this scoping review is to describe the state of the literature applying NMES during immobilization to treat upper and lower extremity musculoskeletal conditions.

Application of digital classification based on AO classification in floating knee injury.

Objective: A digital classification system based on AO classification was adopted to study and summarize different types of floating knee injuries.

Methods: One hundred cases with a floating knee injury from March 2005 to December 2020 were collected, including 74 males and 26 females with an average age of 43.74 years.

The Midline Lateral Parapatellar Arthrotomy: A Safe Alternative Approach for Lateral Tibial Plateau Fractures.

Objectives: The midline lateral parapatellar (LP) approach has been shown in a cadaveric study to provide superior articular exposure compared to the anterolateral approach (AL). The purpose of this study was to report on outcomes and complications with the LP approach.

Methods: Design: Retrospective comparative cohort study and prospective cohort.

Previous Hip or Knee Arthroplasty is Associated With Less Favorable Patient-reported Outcomes of Lumbar Surgery.

Study Design: Review of cohort studies.

Objective: To ascertain if previous hip (THA) or knee (TKA) arthroplasty was associated with patients' outcomes assessments of subsequent lumbar surgery, specifically overall satisfaction, less disability due to pain, and an affective appraisal reflecting emotional assessment of results.

Background: Hip, knee, and lumbar symptoms often co-exist and increasingly are managed with surgery.

Clinical and Functional Outcomes of Knee Arthrodesis by Charnley's External Fixator.

Background Knee arthrodesis was originally developed to manage severe joint infections such as tuberculosis before the advent of antibiotics and joint replacement techniques. The procedure aims to eliminate pain and infection by stabilizing the knee joint through bone fusion. Knee arthrodesis remains essential for cases where total knee arthroplasty is not feasible, such as in patients with severe bone loss, chronic infections, or failed knee replacements.

Concurrent avulsion of posterior cruciate ligament and semimembranosus: a case-based discussion and literature review.

A 30-year-old male sustained a road traffic accident and presented to our trauma centre with injuries to his pelvis and right knee. Radiology showed closed fractures of the right posterior wall and posterior column of the acetabulum and PCL bony avulsion with posteromedial tibial plateau osteochondral fracture, without any distal neurovascular deficit. He was managed with surgical intervention for both injuries.

The effects of pre-operative anti-osteoporotic use on total joint arthroplasty complications: A national database study.

Background: The current study aims to analyze the effect of pre-operative non-bisphosphonate anti-osteoporotic drugs on complication and revision rates following total joint arthroplasty (TJA).

Methods: A retrospective cohort analysis of the PearlDiver (PearlDiver Technologies, Colorado Springs, CO) database was performed. The database was queried to identify all patients who underwent total hip arthroplasty (THA) or total knee arthroplasty (TKA) with history of hip or knee osteoarthritis and either osteopenia or osteoporosis.

All-Suture Anchor Onlay Fixation for Medial Patellofemoral Ligament Reconstruction: A Biomechanical Comparison of Fixation Constructs.

Background: The use of all-suture anchors (ASAs) for onlay patellar and femoral fixation of medial patellofemoral ligament (MPFL) grafts may provide clinical benefit, particularly in the small or pediatric knee; however, biomechanical data supporting the use of ASAs are lacking.

Purpose/hypothesis: The purpose of this study was to compare ASAs to larger interference implants for MPFL reconstruction in a time-zero biomechanical model. It was hypothesized that ASAs would have comparable cyclic elongation to interference fixation and would exceed published biomechanical values for the native human MPFL.

Fractures in Oxford unicompartmental knee arthroplasty are associated with a decreased medial keel-cortex distance of the tibial implant.

Purpose: This retrospective single-center study aimed to investigate incidence and risk factors influencing tibial periprosthetic fractures (TPF) in Oxford unicompartmental knee arthroplasty (UKA), with a specific focus on tibial component positioning and sizing.

Methods: A total of 2063 patients with medial UKA using the Oxford® mobile partial knee implant were analyzed between July 2014 and September 2022. Various preoperative and postoperative radiographic parameters determining pre- and postoperative alignment and implant positioning, incidence and characteristics of periprosthetic fractures, and patient demographics were assessed.

Non-steroidal anti-inflammatory drugs influence cartilage healing.

Background: Retrograde intramedullary nailing is commonly performed to stabilize distal femoral shaft fractures which may lead to iatrogenic injuries of the knee articular cartilage. The limited regenerative capability of cartilage may further be hindered by intake of non-steroidal anti-inflammatory drugs (NSAIDs) which are usually advised for injuries of the musculoskeletal system. The current study was designed to evaluate the histological changes in the femoral articular cartilage of knee joint after retrograde femoral nailing of rats.

[Arthroscopically assisted suture osteosynthesis of tibial eminence fractures in children and adolescents].

Objective: The surgical goal is the arthroscopically assisted, closed reduction, and suture osteosynthesis of fractures of the tibial eminence in children and adolescents.

Indications: Fractures of the tibial eminence type (II)-III according to Meyers & McKeever or type IV according to Zaricznyj.

Contraindications: Fracture of the tibial eminence type I, conservatively treatable fracture type II according to Meyers & McKeever and ligamentous rupture of the anterior cruciate ligament.

Tibial Baseplate Microstructure Governs High Cycle Fatigue Fracture In Vivo.

Previous studies report rare occurrences of tibial baseplate fractures following primary total knee arthroplasty (TKA). However, at a microstructural scale, it remains unclear how fatigue models developed in vitro apply to fractures in vivo. In this study, we asked: (1) do any clinical factors differentiate fracture patients from a broader revision sample; and (2) in vivo, how does microstructure influence fatigue crack propagation? We identified three fractured tibial baseplates from an institutional review board exempt implant retrieval program.
