#1
Min Wei, Yu Wei, Yang Liu
When subchondral bone defects are present in osteochondral lesions of the talus (OCLT), it is inconclusive whether to allow early weightbearing after microfracture treatment because of the lack of effective support of the newly-formed fibrocartilage. After performing arthroscopic debridement and microfracture treatment on OCLT patients with subchondral bone defects, we allowed patients to have an early postoperative weightbearing exercise to observe their clinical outcome. Forty-two OCLT patients with subchondral bone defects were analyzed...

The aim of this randomised, prospective clinical trial was to determine how the administration of a low dose of dexmedetomidine (DEX) by IV constant rate infusion, modified the duration of the nerve block in dogs undergoing spinal anaesthesia (SA) in a clinical setting. Forty-four dogs undergoing hind limb orthopaedic surgery in a day-surgery regime, maintained under anaesthesia with isoflurane plus SA, were randomly assigned to receive 1 μg/kg/h (IV) of DEX (group D) or not (group C). Spinal anaesthesia was performed with a hyperbaric solution of bupivacaine and morphine at the L5-6 interspace...

INTRODUCTION: Orthopaedic surgery can be a physically demanding occupation with high rates of fatigue and burnout. Fatigue has been shown to affect surgeon performance with higher rates of errors in fatigued surgeons. The metabolic cost of performing surgery has yet to be quantified. A better understanding of these costs may provide insights into surgeon fatigue and its effect on patient safety. METHODS: Eight subjects performed a one-level lumbar laminectomy and fusion on cadavers...

BACKGROUND: Application of surgical navigation for pelvic bone cancer surgery may prove useful, but in addition to the fact that research supporting its adoption remains relatively preliminary, the actual navigation devices are physically large, occupying considerable space in already crowded operating rooms. To address this issue, we developed and tested a navigation system for pelvic bone cancer surgery assimilating augmented reality (AR) technology to simplify the system by embedding the navigation software into a tablet personal computer (PC)...

Surgical site infections (SSI) are a common potentially preventable complication after surgical procedures. A standardized antibiotic prophylaxis in elective orthopaedic surgery plays a major role in lowering SSI. At present, there is little published evidence regarding standardized antibiotic prophylaxis in orthopaedic oncological surgery. We introduced a prophylactic antibiotic protocol for orthopaedic oncological surgery in our hospital. The proposed protocol consists in "one-shot" intravenous administration of Cefazolin 2g, 30 min before surgery...

INTRODUCTION: Although clinical results of anatomic reconstruction using allograft are reportedly good, studies on how accurately the tunnel has been made after surgery are very rare. The purpose of this study was to analyze the postoperative locations of the tunnels through 3-dimensional computed tomography (3D-CT) after anatomic ligament reconstruction and to evaluate its clinical results. HYPOTHESIS: We hypothesized that anatomic lateral ligament reconstruction could lead to excellent results in clinical outcomes by repositioning anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) accurately...

REVIEW
Katy Kim, Mark Zhu, Jacob T Munro, Simon W Young
BACKGROUND: Microbiological contamination of surgical gloves occurs during surgery, which may warrant glove change during orthopaedic surgeries. However, no systematic review of this topic has previously been published. Therefore, this review evaluated whether changing gloves during arthroplasty surgeries reduces the risk of surgical site infection/prosthetic joint infection (SSI/PJI) and the optimal frequency of glove change. METHODS: Search terms such as surgical gloves, surgical site infections, prosthesis-related infections, arthroplasty were used, including Medical Subject Headings terms...

OBJECTIVE: Total knee arthroplasty (TKA) is an established surgical technique and is the standard treatment for degenerative knee joint diseases. However, severe pain after TKA makes it difficult for many patients to perform early postoperative rehabilitation and functional exercise, which might result in subsequent unsatisfactory recovery of knee joint function and great reduction in patients' satisfaction and quality of life. Orthopaedic surgeons have tried a large variety of analgesics and analgesic modes to relieve patients' pain after TKA...

BACKGROUND: Approximately 70,000 to 75,000 proximal femoral fracture repairs take place in the UK each year. Hemiarthroplasty is the preferred treatment for adults aged over 60 years. Postoperative infection affects up to 3% of patients and is the single most common reason for early return to theatre. Ultraclean ventilation was introduced to help mitigate the risk of infection, but it may also contribute to inadvertent perioperative hypothermia, which itself is a risk for postoperative infection...

Background: Fluoroscopic guidance is routinely utilized during hip arthroscopic surgery. Previous studies have shown that the C-arm orientation can significantly affect radiation exposure for both the surgeon and the patient during orthopaedic procedures. However, this has not been previously assessed for hip arthroscopic surgery. Hypothesis: Using an inverted C-arm during hip arthroscopic surgery will reduce radiation exposure to the patient and surgeon. Study Design: Descriptive laboratory study...

PURPOSE: Allograft infection remains the greatest challenge in orthopaedic reconstructive surgery especially methicillin-resistant Staphylococcus aureus (MRSA). This risk can be minimized with the use of antibiotic laden allograft (ALA) via iontophoresis. Ceftaroline fosamil (CF) is an advanced-generation cephalosporin, an alternative treatment for MRSA infections. Its antibacterial activity and safety profile are better than vancomycin. CF iontophoresed bone has not been used before...

PURPOSE: Dexmedetomidine, an alpha 2 receptor agonist, prolongs nerve block duration when administered in conjunction with peripheral nerve blocks. We hypothesised that sedation with dexmedetomidine could also significantly prolong the analgesic duration of brachial plexus block (BPB) during orthopaedic surgery on the upper extremities. MATERIALS AND METHODS: One hundred and two patients received upper extremity surgery under BPB. The patients were randomly sedated with dexmedetomidine (D group) or midazolam (M group) following BPB using 25 mL of local anaesthetics (1:1 mixture of 1% lidocaine and 0...

PURPOSE: Elective hip or knee replacement is an optimal, standardised orthopaedic surgical procedure. The influence of chronic kidney disease, defined as an estimated glomerular filtration rate (eGFR) of 15-45 ml/min/1.73 m2 body surface area (BSA) (KDIGO stage G3a-G4), on the duration of hospitalisation, perioperative decrease in haemoglobin (Hb) levels, and transfusion rates after orthopaedic procedures has not been fully clarified. Our study, therefore, aimed to evaluate the impact of chronic kidney disease on the previously mentioned variables...
