The purpose of this study was to evaluate the safety of simultaneous bilateral TKA compared with that of unilateral TKA. METHODS Patients who underwent unilateral

BACKGROUND Intramedullary nails are commonly used in the treatment of trochanteric and subtrochanteric fractures. We aimed to compare intramedullary nails in widespread use in Norway on the basis of reoperation risk. METHODS We assessed data from 13,232 trochanteric or subtrochanteric fractures treated with an intramedullary nail and registered in the Norwegian Hip Fracture Register between 2007 and

BACKGROUND Hemiepiphysiodesis (guided-growth) procedures have become the primary method of treatment for coronal-plane knee deformities in skeletally immature patients. Two leading techniques involve the use of a transphyseal screw or a growth modulation plate. However, clinical references for the estimation of correction are lacking, and no consensus has been reached regarding the superiority of one

BACKGROUND The Stopping Opioids after Surgery (SOS) score was developed to identify patients at risk for sustained opioid use following surgery. The SOS score has not been specifically validated for patients in a general orthopaedic context. Our primary objective was to validate the SOS score within this context. METHODS In this retrospective cohort study, we considered a broad array of representative

BACKGROUND Sagittal alignment determines the extension and flexion of knee prostheses in total knee arthroplasty (TKA). The definition of the sagittal axes may be different between the Mako TKA system (Stryker) and the conventional manual intramedullary approach. Whether there is any discrepancy between the 2 approaches has not been well studied. METHODS We retrospectively analyzed 60 full-length computed

BACKGROUND Disparities in the utilization of orthopaedic surgery based on race and ethnicity continue to be reported. We examined the impact of sociodemographic factors on treatment recommendation by hand surgeons for carpal tunnel syndrome (CTS) of similar disease severity. METHODS Patients with electrodiagnostic study (EDS)-confirmed CTS were evaluated at a single institution between 2016 and 2020

BACKGROUND The aim of this study was to determine the floor and ceiling effects for both the QuickDASH (shortened version of the Disabilities of the Arm, Shoulder and Hand [DASH] questionnaire) and the PRWE (Patient-Rated Wrist Evaluation) following a distal radial fracture (DRF).

METHODS This study was a network meta-analysis of prospective

BACKGROUND Plate osteosynthesis (referred to throughout as plating) and intramedullary nailing (referred to throughout as nailing) are the most common operative strategies for humeral shaft fractures. However, it is undecided which treatment is more effective. This study aimed to compare functional and clinical outcomes of these treatment strategies. We hypothesized that plating would result in an

The devastating impact of COVID-19 has reshaped how we lead and train our future surgeons in the field of orthopaedics. Overnight, leaders in our field had to dramatically shift their mindset to continue to lead a hospital, department, journal, or residency or fellowship program in the face of an unprecedented level of adversity in the history of the United States. This symposium discusses the role

BACKGROUND Total knee arthroplasty (TKA) is a cost-effective procedure, but it is also associated with substantial postoperative pain. The present study aimed to compare pain relief and functional recovery after TKA among groups that received intravenous corticosteroids, periarticular corticosteroids, or a combination of both. METHODS This randomized, double-blinded clinical trial in a local institution

BACKGROUND Preventive management to reduce the risk of coronavirus disease-2019 (COVID-19) spread led to delays in active rehabilitation, which may have negatively impacted the outcomes of patients with traumatic spinal cord injury (SCI). Therefore, the aim of this study was to clarify the influence of preventive management on the rate of perioperative complications after surgical treatment for SCI

BACKGROUND The spectrum of congenital vertebral defects varies from benign lesions to severe, life-threatening conditions. The etiology and maternal risk factors remain mainly unclear in isolated cases. Hence, we aimed to assess and identify potential maternal risk factors for these anomalies. Based on previous studies, we hypothesized that maternal diabetes, smoking, advanced maternal age, obesity

➤ Clinicians should be careful to assess for associated injuries including anterolateral complex and medial meniscal ramp lesions or lateral meniscal posterior root tears.➤ Consideration of lateral extra-articular augmentation should be given for patients with >12° of posterior tibial slope.➤ Patients with preoperative knee hyperextension (>5°) or other nonmodifiable risk factors, including high-risk

BACKGROUND The increasing frequency of total hip arthroplasty (THA) as well as an aging population indicate that the need for revision THA will continue to grow, especially in older and potentially medically complex patients. The purpose of this study was to compare THA revision indications, perioperative complications, and readmissions between octogenarian and septuagenarian patients. We hypothesized

BACKGROUND Radiographic measurements of initial displacement of tibial plateau fractures and of postoperative reduction are used to determine treatment strategy and prognosis. We assessed the association between radiographic measurements and the risk of conversion to total knee arthroplasty (TKA) at the time of follow-up. METHODS A total of 862 patients surgically treated for tibial plateau fractures

BACKGROUND Medicaid insurance coverage among patients undergoing total hip arthroplasty (THA) or those undergoing total knee arthroplasty (TKA) has been associated with worse postoperative outcomes compared with patients without Medicaid. Surgeons and hospitals with lower annual total joint arthroplasty (TJA) volume have also been associated with worse outcomes. This study sought to characterize the

BACKGROUND Recent advances in high-throughput DNA sequencing technologies have made it possible to characterize the microbial profile in anatomical sites previously assumed to be sterile. We used this approach to explore the microbial composition within joints of osteoarthritic patients. METHODS This prospective multicenter study recruited 113 patients undergoing hip or knee arthroplasty between 2017

BACKGROUND A discoid lateral meniscus (DLM) is more prone to tear, and treatment of this condition is challenging. The purpose of the present study was to investigate (1) whether a torn DLM is associated with more varus alignment than a torn semilunar lateral meniscus (SLM) and (2) whether the lower-limb alignment associated with a torn DLM changes with age. METHODS Consecutive patients who underwent

BACKGROUND Multiligament knee injury (MLKI) with associated extensor mechanism (EM) involvement is a rare injury, with limited evidence to guide optimal treatment. The purpose of this study was to identify areas of consensus among a group of international experts regarding the treatment of patients with MLKI and concomitant EM injury. METHODS Utilizing a classic Delphi technique, an international group

BACKGROUND Several studies of distal radial fractures have investigated final displacement and its association with clinical outcomes. There is still no consensus on the importance of radiographic outcomes, and published studies have not used the same criteria for acceptable alignment. Previous reports have involved the use of linear or dichotomized analyses. METHODS The present study included 438
