Watching a movie or listening to music is effective in managing perioperative anxiety and pain: a randomised controlled trial.

Purpose: Despite the use of perioperative anxiolytics and pain medication, surgery can be a stressful and painful experience. Providing patients with distractions using video and/or audio tools in addition to medication may be helpful. To date, no studies have compared different distraction modalities in a same-day surgical setting in adults.

Platelet-Rich Plasma Injections for the Treatment of Ankle Osteoarthritis.

Background: Ankle osteoarthritis is debilitating and usually affects relatively young people, often as a result of previous ankle traumas, frequently occurring in sports. Platelet-rich plasma (PRP) injections for ankle osteoarthritis have shown no evidence of benefit over the course of 26 weeks. Previous studies on PRP for knee osteoarthritis showed that clinically significant improvements with PRP occurred between 6 to 12 months in the absence of initial benefit.

Analysis of Facilitators and Barriers to the Delivery of Routine Care during the COVID-19 Global Pandemic: A Systematic Review.

The delivery of routine health care during the COVID-19 global pandemic continues to be challenged as public health guidelines and other local/regional/state and other policies are enforced to help prevent the spread of the virus. The objective of this systematic review is to identify the facilitators and barriers affecting the delivery of routine health care services during the pandemic to provide a framework for future research. In total, 32 articles were identified for common themes surrounding facilitators of routine care during COVID-19.

Feasibility of Collecting Multiple Patient-Reported Outcome Measures Alongside the Dutch Arthroplasty Register.

Background: Compliance rates with patient-reported outcome measures (PROMs) collected alongside arthroplasty registries vary in the literature. We described the feasibility of a routinely collected set PROMs alongside the Dutch Arthroplasty Register.

Methods: The longitudinal Leiden Orthopaedics Outcomes of OsteoArthritis Study is a multicenter (7 hospitals), observational study including patients undergoing total hip or total knee arthroplasty (THA or TKA).

Platelet-Rich plasma Injection Management for Ankle osteoarthritis study (PRIMA): protocol of a Dutch multicentre, stratified, block-randomised, double-blind, placebo-controlled trial.

Introduction: Platelet-rich plasma (PRP) is a potentially efficacious treatment for ankle osteoarthritis (OA), but its use has not been examined in high-quality studies. Systematic reviews show that PRP injections significantly decrease pain and improve function in patients with knee OA. Ankle OA is more common than hip or knee OA in the young active population; with a prevalence of 3.

Diagnosis, treatment and prevention of ankle sprains: update of an evidence-based clinical guideline.

This guideline aimed to advance current understandings regarding the diagnosis, prevention and therapeutic interventions for ankle sprains by updating the existing guideline and incorporate new research. A secondary objective was to provide an update related to the cost-effectiveness of diagnostic procedures, therapeutic interventions and prevention strategies. It was posited that subsequent interaction of clinicians with this guideline could help reduce health impairments and patient burden associated with this prevalent musculoskeletal injury.

Arthroscopic Capsular Shrinkage for Treatment of Chronic Lateral Ankle Instability.

Background: Capsular shrinkage is an arthroscopic stabilization technique that can be used in patients with chronic ankle instability (CAI), if desired in addition to primary arthroscopic procedures. Despite positive short-term results, long-term follow-up of these patients has not yet been performed. Therefore, our objective was to assess whether capsular shrinkage still provided functional outcome after 12-14 years compared to preoperative scores.

Effects of Pulsed Electromagnetic Fields on Return to Sports After Arthroscopic Debridement and Microfracture of Osteochondral Talar Defects: A Randomized, Double-Blind, Placebo-Controlled, Multicenter Trial.

Background: Osteochondral defects (OCDs) of the talus usually affect athletic patients. The primary surgical treatment consists of arthroscopic debridement and microfracture. Various possibilities have been suggested to improve the recovery process after debridement and microfracture.

Prediction of human's ability in sound localization based on the statistical properties of spike trains along the brainstem auditory pathway.

The minimum audible angle test which is commonly used for evaluating human localization ability depends on interaural time delay, interaural level differences, and spectral information about the acoustic stimulus. These physical properties are estimated at different stages along the brainstem auditory pathway. The interaural time delay is ambiguous at certain frequencies, thus confusion arises as to the source of these frequencies.

Interventions for treating chronic ankle instability.

Background: Chronic lateral ankle instability occurs in 10% to 20% of people after an acute ankle sprain. Initial treatment is conservative but if this fails and ligament laxity is present, surgical intervention is considered.

Objectives: To compare different treatments, conservative or surgical, for chronic lateral ankle instability.

Pulsed electromagnetic fields after arthroscopic treatment for osteochondral defects of the talus: double-blind randomized controlled multicenter trial.

Background: Osteochondral talar defects usually affect athletic patients. The primary surgical treatment consists of arthroscopic debridement and microfracturing. Although this is mostly successful, early sport resumption is difficult to achieve, and it can take up to one year to obtain clinical improvement.

Stochastic properties of coincidence-detector neural cells.

Neural information is characterized by sets of spiking events that travel within the brain through neuron junctions that receive, transmit, and process streams of spikes. Coincidence detection is one of the ways to describe the functionality of a single neural cell. This letter presents an analytical derivation of the output stochastic behavior of a coincidence detector (CD) cell whose stochastic inputs behave as a nonhomogeneous Poisson process (NHPP) with both excitatory and inhibitory inputs.

Arthroscopic capsular shrinkage for chronic ankle instability with thermal radiofrequency: prospective multicenter trial.

The study was designed as a prospective multicenter longitudinal trial. Adult patients with symptomatic mechanical chronic ankle instability, not improving with conservative therapy, were included and underwent surgery. Primary outcome measures were radiological and manually tested mechanical laxity.

Stochastic properties of auditory brainstem coincidence detectors in binaural perception.

In the mammalian auditory brainstem, two types of coincidence detector cells are involved in binaural localization: excitatory-excitatory (EE) and excitatory-inhibitory (EI). Using statistics derived from EE and EI spike trains, binaural discrimination abilities of single tones were predicted. The minimum audible angle (MAA), as well as the just noticeable difference of interaural time delay (ITD) and interaural level difference (ILD) were analytically derived for both EE and EI cells on the basis of two possible neural coding patterns, rate coding that ignores a spike's timing information and all-information coding (AIN), which considers a spike's timing occurrences.

Reporting of outcomes in orthopaedic randomized trials: does blinding of outcome assessors matter?

Background: Randomization, concealment of treatment allocation, and blinding are all known to limit bias in clinical research. Nonsurgical studies that fail to meet these standards have been reported to inflate the differences between treatment and control groups. While surgical trials can rarely blind surgeons or patients, they can often blind outcome assessors.

Interventions for treating chronic ankle instability.

Background: Chronic lateral ankle instability occurs in 10% to 20% of people after an acute ankle sprain. The initial form of treatment is conservative but if this fails and ligament laxity is present, surgical intervention is considered.

Objectives: To compare different treatments, both conservative and surgical, for chronic lateral ankle instability.

Does a "Level I Evidence" rating imply high quality of reporting in orthopaedic randomised controlled trials?

Background: The Levels of Evidence Rating System is widely believed to categorize studies by quality, with Level I studies representing the highest quality evidence. We aimed to determine the reporting quality of Randomised Controlled Trials (RCTs) published in the most frequently cited general orthopaedic journals.

Methods: Two assessors identified orthopaedic journals that reported a level of evidence rating in their abstracts from January 2003 to December 2004 by searching the instructions for authors of the highest impact general orthopaedic journals.

Prospective study on diagnostic strategies in osteochondral lesions of the talus. Is MRI superior to helical CT?

Our aim in this prospective study was to determine the best diagnostic method for discriminating between patients with and without osteochondral lesions of the talus, with special relevance to the value of MRI compared with the new technique of multidetector helical CT. We compared the diagnostic value of history, physical examination and standard radiography, a 4 cm heel-rise view, helical CT, MRI, and diagnostic arthroscopy for simultaneous detection or exclusion of osteochondral lesions of the talus. A consecutive series of 103 patients (104 ankles) with chronic ankle pain was included in this study.

The anterior ankle impingement syndrome: diagnostic value of oblique radiographs.

Background: The diagnostic value of an oblique radiograph, in addition to a lateral radiograph, for detecting osteophytes in the anterior ankle impingement syndrome was evaluated in a prospective study. The hypothesis was that the application of a lateral radiograph is insufficient to detect osteophytes that are located in the anteromedial aspect of the ankle joint. Oblique anteromedial impingement (AMI) radiographs were hypothesized to be a relevant adjunct, because of their utility to detect these anteromedially located osteophytes.

Operative and functional treatment of rupture of the lateral ligament of the ankle. A randomised, prospective trial.

Consecutive patients with a confirmed rupture of at least one of the lateral ligaments of the ankle were randomly assigned to receive either operative or functional treatment. They were evaluated at a median of 8 years (6 to 11). In total, 370 patients were included.

Treatment of a large intraosseous talar ganglion by means of hindfoot endoscopy.

We report on 2 patients with a large intraosseous ganglion of the talus who were treated by means of a 2-portal endoscopic approach of the hindfoot with the patient in the prone position. By means of this approach, it is possible to visualize, debride, and graft a large intraosseous talar lesion. In both patients, the lesions were treated successfully, with no recurrence at follow up.

Anatomical reconstruction and Evans tenodesis of the lateral ligaments of the ankle. Clinical and radiological findings after follow-up for 15 to 30 years.

In this retrospective study, we assessed the outcome in 99 patients who underwent reconstruction of the lateral ligaments of the ankle for chronic anterolateral instability with a minimum follow-up of 15 years. Two techniques were compared: 54 patients had an anatomical reconstruction (AR group) and 45 had an Evans tenodesis (ET group). They were followed up for 19.
