INTRODUCTION: Cardiac complications represents a major cause of morbidity and mortality especially after bilateral simultaneous total knee arthroplasty (BS-TKA). Takotsubo syndrome after BS-TKA has not been described in the literature. CASE PRESENTATION: A 60 years-old women underwent BS- TKA and she suddenly developed bradycardia and hypotension after second knee wound closure. The electrocardiography revealed ST elevation and echocardiography showed apical hypokinesia of left ventricle...

BACKGROUND: Elastic band exercises can improve bone density, muscle quality, and body fat in elderly patients with Sarcopenic Obesity Syndrome (SOS), a common diagnosis. Encouraging this exercise can bring significant benefits. METHODS: We conducted a comprehensive search until April 1, 2023, covering UpToDate, PubMed, and Web of Science databases. The analysis focused on osteosarcopenic obesity and resistance training, involving four randomized controlled trials with 108 participants...

INTRODUCTION: Although gluteal tears have been observed in a substantial percentage of total hip arthroplasty (THA) patients and hip osteoarthritis (OA) has been shown to alter the function of the gluteal muscles, the association between gluteal tears and hip OA has not been characterized. Therefore, we evaluated (1) the overlap between hip OA and gluteal tears, (2) the relative risks of gluteal tears in patients who have hip OA, and (3) gluteal tear-free survival after diagnosis or treatment for hip osteoarthritis...

PURPOSE: Open decompression is currently the standard surgical procedure for symptomatic OLF. As the minimal invasive method gains popularity, UBE is considered a reliable technique with less complication. However, the outcome is still in question. This study aimed to evaluate and compare UBE versus open surgery in symptomatic OLF cases. METHODS: We evaluated 35 patients with single- or two-level thoracic OLF, underwent decompression by open or UBE. Surgery duration, estimated blood loss, and LOS were recorded as intraoperative parameters...

INTRODUCTION: The preclusion of obese patients from unicompartmental knee arthroplasty (UKA) has increasingly been challenged. This study aimed to evaluate the impact of Body Mass Index (BMI) on UKA at 15-year follow-up. MATERIALS AND METHODS: 169 unilateral UKA patients from 2003 to 2007 were followed-up prospectively for at least 15 years. 70 patients were left for analysis after accounting for patient demise, revision surgery and loss to follow-up. 48 of these patients (69%) were in the Control group (BMI <30 kg/m2 ) and 22 (31%) were in the Obese group (BMI ≥30 kg/m2 )...

INTRODUCTION: Previously published studies have hypothesized that total hip arthroplasty (THA) requires the surgeon to expend more energy that total knee arthroplasty (TKA). However, techniques for performing these procedures have evolved. Therefore, we sought to compare if primary THA had increased energy expenditure compared to primary TKA. METHODS: We prospectively recorded the heart rate, respiratory rate, minute ventilation, cadence, and energy expenditure of a single fellowship-trained arthroplasty surgeon while performing primary THA and TKA on 372 patients...

INTRODUCTION: The advantages of outpatient surgery have been shown in other orthopedic subspecialities to be a means of driving down costs and reducing the average length of hospital stay. However, there is a scarcity of literature examining the utility of a specific, hospital-based facility performing such procedures for limb lengthening. Considering this, we aimed to investigate surgical factors, patient characteristics, and the incidence of outpatient postoperative complications for patients undergoing surgery and subsequent distraction osteogenesis utilizing the Precice® nail, a state-of-the-art magnetic intramedullary nail (MILN)...

INTRODUCTION: Robotic-assisted (RA) and computer-navigated (CN) total hip arthroplasty (THA) have been demonstrated to improve component placement accuracy compared to manual THA (mTHA) for primary osteoarthritis. As hip dysplasia presents several additional challenges in component placement accuracy and leg length discrepancy (LLD) correction during THA, a systematic review was conducted to evaluate whether utilizing these platforms may be associated with superior outcomes over mTHA in patients who have hip dysplasia...

INTRODUCTION: With the increasing incidence of total knee arthroplasty (TKA), there is an expected rise in rate of periprosthetic fractures in the coming years. It is unclear how the outcomes of patients with distal femur fractures (DFF) and a total knee arthroplasty compare to patients of the same age group with native knees (NK). MATERIALS AND METHODS: A retrospective review was completed for distal femur fractures treated with surgical fixation from January 2019-March 2021...

BACKGROUND: Developmental Coxa Vara (DCV) consists on a pathological reduction in head-shaft angle (HSA) and increased femoral retroversion. Several case series reported outcomes on proximal femoral valgus osteotomy (PFVO), but no evidence synthesis had been conducted. This systematic review aimed to (1) analyze success rate and complications, (2) report the degree of correction according to the HSA and the Hilgenreiner Epiphyseal Angle (HEA), compare success rate and degree of correction of subtrochanteric (SVO) vs intertrochanteric (IVO) osteotomy, and (4) difference in success rate and correction between patients in which an internal (IF) or external fixation (EF) technique was used...

INTRODUCTION: Prosthetic joint infection (PJI) risk continues to receive much attention given its associated morbidity and costs to patients and healthcare systems. It has been hypothesized that invasive colonoscopies may increase the risk of PJI. However, the decision to administer antibiotic prophylaxis lacks clinical guidance. In this study we aimed to compare PJI rates in patients undergoing colonoscopies with and without antibiotic prophylaxis against a control group, analyzing PJI occurrences at 90 days, 6 months, 9 months, and 1-year post-procedure and (2) assess the impact of antibiotic prophylaxis on PJI rates to inform clinical guidelines...

INTRODUCTION: Giant Cell Tumours (GCT) are benign tumours with aggressive potential that disrupt the local bony architecture, which can be especially problematic in peri-articular locations. Our aim was to assess the outcomes of patients with GCT of the distal ulna who were treated by resection without reconstruction. METHODS: The study included 21 patients with distal ulna GCT that were treated with resection without reconstruction. There were 12 males and 9 females, with a mean age of 30...

BACKGROUND: Currently there is limited literature available on fungating soft tissue sarcoma and its effect of outcomes. In the current study we evaluated the surgical management and oncologic outcomes of patient with fungating soft tissue sarcoma. MATERIALS AND METHODS: This was a retrospective observational study of patients with fungating sarcoma between January 2015 till January 2019 at a tertiary cancer care centre. A total of 59 patients were considered of which 16 had metastasis at presentation...

INTRODUCTION: Osteoporosis is a geriatric metabolic ailment distinguished by low bone mineral density (BMD) and strength with enhanced micro-architectural retrogression of the extracellular matrix, further increasing bone fragility risk. Osteoporotic fractures and associated complications become common in women and men after 55 and 65 years, respectively. The loss in BMD markedly enhances the risk of fracture, non-skeletal injury, and subsequent pain, adversely affecting the quality of life...

Posterior pilon variant ankle fractures (PPVF) are a unique subtype of posterior malleolar fractures which have been a source of controversy and confusion in recent years. There has not been a thorough literature review previously written on the topic. Database searches of PubMed and Embase were conducted from inception until June 2023. The key words included "pilon variant," "posterior pilon variant," and "posterior pilon" fractures. Outcomes were evaluated by union time, rates of delayed union, nonunion, malunion, and complication...

Fracture-related infection (FRI) is a devasting complication for both patients and their treating Orthopaedic surgeon that can lead to loss of limb function or even amputation. The unique and unpredictable features of FRI make its diagnosis and treatment a significant challenge. It has substantial morbidity and financial implications for patients, their families and healthcare providers. In this article, we perform an in-depth and comprehensive review of FRI through recent and seminal literature to highlight evolving definitions, diagnostic and treatment approaches, focusing on common pathogens such as Staphylococcus aureus , polymicrobial infections and multi-drug-resistant organisms (MDRO)...

BACKGROUND: Radiotherapy is considered a cornerstone as adjuvant or neo adjuvant to surgery in extremity soft tissue sarcoma (ESTS). Wound complications are the most agonizing complication that may have an impact on patient's functional outcome following radiotherapy. The best care for ESTS is by combining extensive surgical excision with safety margin and radiotherapy either preoperative (neoadjuvant) or postoperative. Preoperative radiotherapy allows for lower dose of radiation over smaller fields which is supposed to decrease long-term complications...

INTRODUCTION: In recent years, the utilization of hip arthroscopy to treat femoroacetabular impingement syndrome (FAIS) has increased due to its low complication rates, positive impact on patient-reported outcomes (PROs), and association with faster rehabilitation. Despite this, there are high rates of revision and conversion to total hip arthroplasty (THA) in some of these patients. It is unclear whether time from initial FAIS diagnosis to surgery is a risk factor for poor outcomes. In this study, we examined the relationship between timing of hip arthroscopy for FAIS and rates of 2-year revision hip procedures, 2-year conversion to total hip arthroplasty (THA), post-operative medical complications, and opioid prescriptions...

PURPOSE: The purpose of this study was to evaluate the reproducibility of the native anterior cruciate ligament (ACL) mid-substance cross sectional area in anatomic single-bundle ACL reconstruction. METHODS: Fifty-eight subjects who were performed anatomic single-bundle ACL reconstruction were included. Cross section size of the ACL graft was calculated from the graft diameter during surgery. Computed tomography (CT) of the knee was performed pre-operatively. Following Iriuchishima's report, native ACL size was estimated from the axial CT image of intercondylar notch area of femur at the most distal level of Blumensaat's line (In the report, native ACL size was equal to 14% of the intercondylar notch area of femur)...

BACKGROUND: Cubital tunnel syndrome (CUTS) is a common upper limb compression neuropathy with significant consequences when left untreated. Surgical decompression remains gold-standard treatment for moderate to severe disease, however the optimal operative technique remains unclear. This network meta-analysis (NMA) of Level I and II randomised prospective studies aims to discern superiority between open in-situ, endoscopic and anterior transposition (subcutaneous or submuscular techniques) with respect to the primary outcome of response-to-treatment and secondary outcomes which include complications, post-operative chronic pain VAS scale, return to work and re-operation...
