Early Weight Bearing Is Not Associated with Short-Term Complications in Ankle Fractures.

Ankle fractures are common injuries and post-operative protocols continue to vary. We aim to compare postoperative complications between early weight bearing (EWB), intermediate weight bearing (IWB), and delayed weight bearing (DWB) in adult patients with isolated ankle fractures treated with open reduction internal fixation (ORIF). This retrospective cohort study includes 233 adult patients with isolated (medial malleolar, lateral malleolar, posterior malleolar, bimalleolar equivalent) or complex (trimalleolar, trimalleolar equivalent, bimalleolar, and Maisonneuve) ankle fractures treated with ORIF between 2020 and 2022 at a level I trauma center.

A Bedside-to-Bench-to-Bedside Journey to Advance Osteochondral Allograft Transplantation towards Biologic Joint Restoration.

More than 70 million adults in the United States are impacted by osteoarthritis (OA). Symptomatic articular cartilage loss that progresses to debilitating OA is being diagnosed more frequently and earlier in life, such that a growing number of active patients are faced with life-altering health care decisions at increasingly younger ages. Joint replacement surgeries, in the form of various artificial arthroplasties, are reliable operations, especially for older (≥65 years), more sedentary patients with end-stage OA, but have major limitations for younger, more active patients.

The Family Snapshot-Innovation to integrate family context into daily interactions in the NICU.

Aim: Current literature favours individualised decision making, an approach that requires understanding patients within their context and tailoring treatment and recommendations to their unique needs. In neonatology, family context becomes synonymous with patient context. In the neonatal intensive care unit (NICU), the team may be challenged to understand the intricacies of the family context, paramount for both families and clinicians.

Development and validation of a preclinical canine model for early onset fracture-related infections.

Fracture-related infections (FRIs) are a challenging complication in orthopaedics. Standard of care management for FRIs typically involves prolonged antibiotic therapies, irrigation and debridement (I&D) of the fracture site, and retention of fracture-fixation implants with or without exchange. Unfortunately, this treatment regimen is associated with treatment failure rates of up to 38 %, such that improved preventive and therapeutic interventions are needed.

Midterm Outcomes After Osteochondral Allograft Transplantation in the Knee Using High-Chondrocyte Viability Grafts.

Background: Osteochondral allograft transplantation (OCAT) has become a standard-of-care treatment option for patients with large symptomatic articular defects. Recent advances in allograft science and OCAT protocols have been reported to result in consistently robust outcomes after OCAT in the knee. However, only short-term comparisons have been reported, and analyses are lacking for treatment failure risk factors that account for confounding variables.

Prospective Assessment of Outcomes After Femoral Condyle Osteochondral Allograft Transplantation With Concurrent Meniscus Allograft Transplantation.

Background: Osteochondral allograft transplantation (OCAT) and meniscus allograft transplantation (MAT) have each become more commonly implemented for the treatment of young to middle-aged patients with complex knee pathology. Evidence regarding tibiofemoral OCAT in the setting of concurrent MAT is limited.

Purpose/hypothesis: The purpose of this study was to characterize outcomes for femoral condyle OCAT with concurrent MAT (OCAT+MAT) in the ipsilateral compartment of patients after evidence-based shifts in practice.

Musculoskeletal Injury in Australian Infantry Personnel: A Cross-sectional Study to Understand Prevention Priorities.

Introduction: Musculoskeletal injury patterns are under-investigated in the Royal Australian Infantry Corps. Subsequently, more evidence is needed to support injury prevention processes in this population. One difficulty in collecting injury information to monitor injury patterns within combat populations accurately is known injury concealment behaviors in such populations.

Multiligament knee injury (MLKI): an expert consensus statement on nomenclature, diagnosis, treatment and rehabilitation.

Multiligament knee injuries (MLKIs) represent a broad spectrum of pathology with potentially devastating consequences. Currently, disagreement in the terminology, diagnosis and treatment of these injuries limits clinical care and research. This study aimed to develop consensus on the nomenclature, diagnosis, treatment and rehabilitation strategies for patients with MLKI, while identifying important research priorities for further study.

Enrollment in a Behavioral Health Program Positively Impacts 2-Year Cumulative Survival Rates in Osteochondral Allograft Transplant Patients.

Emerging evidence suggests that patients' behavioral health may influence outcomes after osteochondral allograft transplantation (OCAT). A comprehensive behavioral health program (BHP) including preoperative screening and education, and postoperative counseling and support, led by a health behavior psychologist was implemented for patients considering OCAT. We hypothesized that patients undergoing knee OCAT and enrolled in the BHP would have a significantly higher 2-year graft survival rate than those not enrolled.

Donor-recipient age- or sex-mismatched osteochondral allografts do not adversely affect cumulative graft survival rates after transplantation in the knee.

Background: Osteochondral allograft transplantation (OCAT) can be performed without the need for blood-type matching or anti-rejection medications. However, other donor-recipient mismatch variables could influence outcomes. Therefore, it is critical to examine the impacts of sex and age mismatching on functional OCA survival.

Initial Outcomes following Fresh Meniscus Allograft Transplantation in the Knee.

Based on recent evidence-based advances in meniscus allograft transplantation (MAT), fresh (viable) meniscus allografts have potential for mitigating key risk factors associated with MAT failure, and preclinical and clinical data have verified the safety of fresh meniscus allografts as well as possible efficacy advantages compared with fresh-frozen meniscus allografts. The objective of this study was to prospectively assess clinical outcomes for the initial cohort of patients undergoing MAT using fresh meniscus allografts at our center. Patients who were prospectively enrolled in a dedicated registry were included for analyses when they had undergone primary MAT using a fresh meniscus allograft for treatment of medial and/or lateral meniscus deficiency with at least 1-year follow-up data recorded.

Tunnel Overlap Occurs 25% of the Time With Simultaneous Anterior Cruciate Ligament Reconstruction and Lateral Meniscal Root Repair.

Purpose: To assess the risk of socket-tunnel overlap for posterior medial or lateral meniscal root repair combined with anterior cruciate ligament reconstruction (ACLR) using artificial tibias and computed tomography scans for 3-dimensional modeling.

Methods: Artificial tibias (n = 27; n = 3/subgroup) were allocated to groups based on inclination of socket-tunnels (55°, 60°, 65°) created for posterior root of the medial meniscus (MMPR) and lateral meniscus posterior root (LMPR) repair, and ACLR. Three standardized socket-tunnels were created: one for the ACL and one for each posterior meniscal root insertion.

Optimizing Socket-Tunnel Position for Meniscal Allograft Transplantation Combined With ACL Reconstruction: A 3D Model Analysis.

Background: Socket-tunnel overlap during meniscal allograft transplantation (MAT) combined with anterior cruciate ligament reconstruction (ACLR) may compromise graft integrity and lead to impaired fixation and treatment failure.

Purpose/hypothesis: The purpose of this study was to determine optimal socket-tunnel drilling parameters for medial and lateral MAT with concurrent ACLR using artificial tibias and computed tomography (CT) scans for 3-dimensional (3D) modeling. It was hypothesized that clinically relevant socket tunnels could be created to allow for concurrent medial or lateral MAT and ACLR without significant risk for overlap at varying tunnel guide angles.

Cell-Mediated Immune Responses May Play Roles in Osteochondral Allograft Transplantation Osteointegration Failures.

Prolonged and incomplete osteochondral allograft (OCA) osteointegration is consistently cited as a major mechanism for OCA treatment failure. Subrejection immune responses may play roles in this mode of failure. Preimplantation OCA preparation techniques, including subchondral bone drilling, thorough irrigation, and autogenous bone marrow aspirate concentrate saturation, may dampen immune responses and improve OCA osteointegration.

Accelerated versus Standard Rehabilitation after Meniscus Allograft Transplantation in the Knee.

Meniscus allograft transplantation (MAT) is a proven treatment option for patients with symptomatic irreparable meniscus deficiency. When patients are adherent to prescribed postoperative restriction and rehabilitation protocols, outcomes after MAT are considered good to excellent. However, nonadherence to standard protocols is common and can be associated with undesirable outcomes and patient dissatisfaction.

Superiority and cost-effectiveness of Individual Placement and Support versus standard employment support for people with alcohol and drug dependence: a pragmatic, parallel-group, open-label, multicentre, randomised, controlled, phase 3 trial.

Background: Individual Placement and Support (IPS) is a specialist intervention to help people attain employment in the open competitive labour market. IPS has been developed in severe mental illness and other disabilities, but it is of unknown effectiveness for people with alcohol and drug dependence. The Individual Placement and Support-Alcohol and Drug (IPS-AD) is the first superiority trial to evaluate effectiveness and cost-effectiveness.

Treatment failures (revision or arthroplasty) after knee osteochondral allograft transplantation with minimum two-year follow-up.

Background: Knee osteochondral allograft transplantation (OCAT) has been associated with good short- to mid-term outcomes, however, treatment failures occur more frequently than desired. This study used data from a lifelong outcomes registry to analyze knee OCAT treatment failure rates, variables associated with knee OCAT treatment failures, and outcomes after revision or arthroplasty surgery for knee OCAT treatment failures.

Methods: Patient outcomes were followed after knee OCAT performed using standard preservation (SP) or Missouri Osteochondral Preservation System (MOPS®) allografts.

Meniscus Allograft Transplantation With Bone Plugs Using Knotless All-Suture Anchors and Cortical Button Suspensory Fixation.

Meniscus allograft transplantation can be successful for treatment of meniscal deficiency using a number of transplant techniques. In this Technical Note, we describe a double bone plug medial meniscus allograft transplantation technique that uses knotless all-suture anchors with cortical-button suspensory fixation. This technique maintains the reported advantages for bone-plug fixation while mitigating the risk for meniscal root damage, facilitating easier bone plug insertion and seating, expanding tensioning capabilities, and preventing soft-tissue irritation from suture knot stacks.

Epidemiology of musculoskeletal injury in military recruits: a systematic review and meta-analysis.

Background: Injuries are a common occurrence in military recruit training, however due to differences in the capture of training exposure, injury incidence rates are rarely reported. Our aim was to determine the musculoskeletal injury epidemiology of military recruits, including a standardised injury incidence rate.

Methods: Epidemiological systematic review following the PRISMA 2020 guidelines.

Making the Case for Hyperosmolar Saline Arthroscopic Irrigation Fluids: A Systematic Review of Basic Science, Translational, and Clinical Evidence.

Commonly used isotonic arthroscopic irrigation fluids, such as normal saline or lactated Ringer's, were initially formulated for intravenous administration so they do not replicate the physiologic properties of healthy synovial fluid. Synovial fluid plays an important role in regulating joint homeostasis such that even transient disruptions in its composition and physiology can be detrimental. Previous studies suggest that hyperosmolar solutions may be a promising alternative to traditional isotonic fluids.

Impacts of Knee Arthroplasty on Activity Level and Knee Function in Young Patients: A Systematic Review.

The annual demand for knee arthroplasty has been steadily rising, particularly in younger patients. The primary objective of this systematic review was to determine the impact of knee arthroplasties on knee function and activity levels in young (≤55 years) patients. A PubMed search from inception (1977) to March 2022 to identify eligible studies produced 640 peer-reviewed studies for consideration.

Using a Markerless Motion Capture System to Identify Preinjury Differences in Functional Assessments.

Functional assessments identify biomechanical issues which may indicate risk for injury and can be used to monitor functional recovery after an injury or surgery. Although the gold standard to assess functional movements is marker-based motion capture systems, these are cost prohibitive and have high participant burden. As such, this study was conducted to determine if a markerless motion capture system could detect preinjury differences in functional movements between those who did and did not experience a noncontact lower extremity injury (NCLEI).
