Early Motion and Directed Exercise (EMADE) following ankle fracture fixation: a pragmatic randomized controlled trial.

Aims: This study aimed to compare the outcomes of two different postoperative management approaches following surgical fixation of ankle fractures: traditional cast immobilization versus the Early Motion and Directed Exercise (EMADE) programme.

Methods: A total of 157 patients aged 18 years or older who underwent successful open reduction and internal fixation (ORIF) of Weber B (AO44B) ankle fractures were recruited to this randomized controlled trial. At two weeks post-surgical fixation, participants were randomized to either light-weight cast-immobilization or the EMADE programme, consisting of progressive home exercises and weekly advice and education.

Functional performance of a bi-layered chitosan-nano-hydroxyapatite osteochondral scaffold: a pre-clinical tribological study.

Osteochondral grafts are used for repair of focal osteochondral lesions. Autologous grafts are the gold standard treatment; however, limited graft availability and donor site morbidity restrict use. Therefore, there is a clinical need for different graft sources/materials which replicate natural cartilage function.

Is there a difference in the analgesic response to intra-articular bupivacaine injection in people with knee osteoarthritis pain with or without central sensitisation? Protocol of a feasibility randomised controlled trial.

Introduction: Pain is the main symptom of osteoarthritis (OA) with approximately 50% of patients reporting moderate-to-severe pain. Total knee replacement (TKR) is the ultimate treatment option to alleviate pain in knee OA. Nevertheless, TKR does not provide complete relief for all as approximately 20% of patients experience chronic postoperative pain.

Implant and patient survival rates using Exeter Trauma Stem hemiarthroplasty in fracture neck of femur patients: The largest study to date.

Introduction: Exeter Trauma Stems (ETS) femoral hemiarthroplasties are based on Exeter THR stems with a few design changes. Little has been published on ETS survival rates to justify their high cost compared to other cheaper implants. This is the largest prospective study to assess ETS implant failure-free survival rates in fracture neck of femur patients (NOF).

A comparative analysis of multidimensional computerized adaptive testing for the DASH and QuickDASH scores in Dupuytren's disease.

The QuickDASH is a short-form version of the DASH questionnaire, the most widely used patient-reported outcome measure in hand surgery. Multidimensional computerized adaptive testing (MCAT) can produce shorter and more precise testing than static short forms, like QuickDASH. We used DASH responses from 507 patients with Dupuytren's disease to develop a MCAT.

Development and in vitro assessment of a bi-layered chitosan-nano-hydroxyapatite osteochondral scaffold.

An innovative approach was developed to engineer a multi-layered chitosan scaffold for osteochondral defect repair. A combination of freeze drying and porogen-leaching out methods produced a porous, bioresorbable scaffold with a distinct gradient of pore size (mean = 160-275 μm). Incorporation of 70 wt% nano-hydroxyapatite (nHA) provided additional strength to the bone-like layer.

What Is Important to Patients Who Are Recovering From an Open Tibial Fracture? A Qualitative Study.

Background: Open tibial fracture research has traditionally focused on surgical techniques; however, despite technological advances, outcomes from these injuries remain poor, with patients facing a sustained reduced quality of life. Research has rarely asked patients what is important to them after an open tibial fracture, and this question could potentially offer great insight into how to support patients. A qualitative study may assist in our understanding of this subject.

Feedback to support examiners' understanding of the standard-setting process and the performance of students: AMEE Guide No. 145.

The ratings that judges or examiners use for determining pass marks and students' performance on OSCEs serve a number of essential functions in medical education assessment, and their validity is a pivotal issue. However, some types of errors often occur in ratings that require special efforts to minimise. Rater characteristics (e.

Short-Term Evaluation of Cellular Fate in an Ovine Bone Formation Model.

The ovine critical-sized defect model provides a robust preclinical model for testing tissue-engineered constructs for use in the treatment of non-union bone fractures and severe trauma. A critical question in cell-based therapies is understanding the optimal therapeutic cell dose. Key to defining the dose and ensuring successful outcomes is understanding the fate of implanted cells, e.

Comparison of rehabilitation interventions in nonoperatively treated distal radius fractures: a randomized controlled trial of effectiveness.

Aims: Following cast removal for nonoperatively treated distal radius fractures, rehabilitation facilitated by advice leaflet and advice video were compared to a course of face-to-face therapy.

Methods: Adults with an isolated, nonoperatively treated distal radius fracture were included at six weeks post-cast removal. Participants were randomized to delivery of rehabilitation interventions in one of three ways: an advice leaflet; an advice video; or face-to-face therapy session(s).

Incidence and risk factors for poor ankle functional recovery, and the development and progression of posttraumatic ankle osteoarthritis after significant ankle ligament injury (SALI): the SALI cohort study protocol.

Background: Ankle sprains are one of the most common musculoskeletal injuries, accounting for up to 5% of all Emergency Department visits in the United Kingdom. Ankle injury may be associated with future ankle osteoarthritis. Up to 70% of ankle osteoarthritis cases may be associated with previous ankle injury.

High mortality following revision hip arthroplasty for periprosthetic femoral fracture.

Aims: To determine mortality risk after first revision total hip arthroplasty (THA) for periprosthetic femoral fracture (PFF), and to compare this to mortality risk after primary and first revision THA for other common indications.

Methods: The study cohort consisted of THAs recorded in the National Joint Registry between 2003 and 2015, linked to national mortality data. First revision THAs for PFF, infection, dislocation, and aseptic loosening were identified.

Self-reported sports injuries and later-life health status in 3357 retired Olympians from 131 countries: a cross-sectional survey among those competing in the games between London 1948 and PyeongChang 2018.

Objective: Describe the self-reported prevalence and nature of Olympic-career injury and general health and current residual symptoms in a self-selected sample of retired Olympians.

Methods: 3357 retired Olympians from 131 countries completed a cross-sectional online survey, distributed by direct email through World Olympians Association and National Olympian Associations databases. The survey captured Olympic sport exposure, significant training and competition injury history (lasting 1 month), general health (eg, depression) during the athlete's career, and current musculoskeletal pain and functional limitations.

The predictive value of quantitative sensory testing: a systematic review on chronic postoperative pain and the analgesic effect of pharmacological therapies in patients with chronic pain.

Studies have suggested that quantitative sensory testing (QST) might hold a predictive value for the development of chronic postoperative pain and the response to pharmacological interventions. This review systematically summarizes the current evidence on the predictive value of QST for chronic postoperative pain and the effect of pharmacological interventions. The main outcome measures were posttreatment pain intensity, pain relief, presence of moderate-to-severe postoperative pain, responders of 30% and 50% pain relief, or validated questionnaires on pain and disability.

Intra-articular Injection Administration in UK Ex-professional Footballers During Their Playing Careers and the Association with Post-career Knee Osteoarthritis.

Background: The long-term risk from knee intra-articular (KIA) injections in professional athletes such as ex-footballers remains unknown. The use of KIA injections is controversial and remains anecdotally prolific as it is perceived as being safe/beneficial. The aim of this study was to determine the number, type and frequency KIA injections administered to retired professional footballers during their playing careers and the associations with post-career knee osteoarthritis (KOA).

Formulating injectable pastes of porous calcium phosphate glass microspheres for bone regeneration applications.

Current trends in regenerative medicine treatments for bone repair applications focus on cell-based therapies. These aim to deliver the treatment via a minimally invasive injection to reduce patient trauma and to improve efficacy. This paper describes the injectability of porous calcium phosphate glass microspheres to be used for bone repair based on their formulation, rheology and flow behavior.

Design: This was a cross-sectional study involving a postal questionnaire, followed by radiographic assessment in a subcohort of responders.

Settings And Participants: Four thousand seven hundred seventy-five questionnaires were sent to retired professional footballers, who had played in the English football league, and 1207 responded.

Porous Phosphate-Based Glass Microspheres Show Biocompatibility, Tissue Infiltration, and Osteogenic Onset in an Ovine Bone Defect Model.

Phosphate-based glasses (PBGs) are bioactive and fully degradable materials with tailorable degradation rates. PBGs can be produced as porous microspheres through a single-step process, using changes in their formulation and geometry to produce varying pore sizes and interconnectivity for use in a range of applications, including biomedical use. Calcium phosphate PBGs have recently been proposed as orthobiologics, based on their in vitro cytocompatibility and ion release profile.

In vitro cellular testing of strontium/calcium substituted phosphate glass discs and microspheres shows potential for bone regeneration.

Phosphate-based glasses (PBGs) are ideal materials for regenerative medicine strategies because their composition, degradation rates, and ion release profiles can easily be controlled. Strontium has previously been found to simultaneously affect bone resorption and deposition. Therefore, by combining the inherent properties of resorbable PBG and therapeutic activity of strontium, these glasses could be used as a delivery device of therapeutic factors for the treatment of orthopaedic diseases such as osteoporosis.

Preoperative Neuropathic Pain-like Symptoms and Central Pain Mechanisms in Knee Osteoarthritis Predicts Poor Outcome 6 Months After Total Knee Replacement Surgery.

Preoperative pain characteristics in patients with osteoarthritis may explain persistent pain after total knee replacement. Fifty patients awaiting total knee replacement and 22 asymptomatic controls were recruited to evaluate the degree of neuropathic pain symptoms and pain sensitization. Patients with OA were pain phenotyped into 2 groups based on the PainDETECT questionnaire: high PainDETECT group (scores ≥19) indicating neuropathic pain-like symptoms and low PainDETECT group (scores <19) indicating nociceptive or mixed pain.

Early motion and directed exercise (EMADE) versus usual care post ankle fracture fixation: study protocol for a pragmatic randomised controlled trial.

Background: Following surgical fixation of ankle fractures, the traditional management has included immobilisation for 6 weeks in a below-knee cast. However, this can lead to disuse atrophy of the affected leg and joint stiffness. While early rehabilitation from 2 weeks post surgery is viewed as safe, controversy remains regarding its benefits.
