Background

Disability and slow return to sport and work after tendon rupture are major challenges. Platelet Rich Plasma (PRP) is an autologous supraphysiological concentration of platelets from whole blood that has demonstrated positive cellular and physiological effects on healing in laboratory conditions but evidence from adequately powered robust clinical trials is lacking. We aimed to determine the clinical efficacy of PRP for treatment of acute Achilles tendon rupture.

Methods

In a placebo-controlled, participant- and assessor-blinded, trial at 19 NHS hospitals we randomly assigned 230 adults starting acute Achilles rupture non-surgical management to PRP injection or dry-needle insertion (placebo) to the rupture gap under local anaesthetic. Patients with confounding or contraindicated concurrent medical conditions were excluded. The primary outcome was muscle-tendon function, assessed by the limb symmetry index (LSI, uninjured limb/injured limb × 100, higher scores better) of the work (Joules) performed during the heel-rise endurance test at 24 weeks. Secondary outcomes were: Achilles Tendon Rupture Score (ATRS, 0–100, higher scores better), quality of life (SF-12), pain, and goal attainment. Trial registration: ISRCTN54992179

Aims

The number of revision total ankle arthroplasties (TAAs) which are undertaken is increasing. Few studies have reported the survival after this procedure. The primary aim of this study was to analyze the survival of revision ankle arthroplasties using large datasets. Secondary aims were to summarize the demographics of the patients, the indications for revision TAA, further operations, and predictors of survival.

Methods

The study combined data from the National Joint Registry and NHS Digital to report the survival of revision TAA. We have previously reported the failure rates and risk factors for failure after TAA, and the outcome of fusion after a failed TAA, using the same methodology. Survival was assessed using life tables and Kaplan Meier graphs. Cox proportional hazards regression models were fitted to compare failure rates.

Aims

When a total ankle arthroplasty (TAA) fails, it can be converted to a fusion or a revision arthroplasty. Despite the increasing numbers of TAAs being undertaken, there is little information in the literature about the management of patients undergoing fusion following a failed TAA. The primary aim of this study was to analyze the survival of fusions following a failed TAA using a large dataset from the National Joint Registry (NJR).

Methods

A data linkage study combined NJR and NHS Digital data. Failure of a TAA was defined as a fusion, revision to a further TAA, or amputation. Life tables and Kaplan-Meier graphs were used to record survival. Cox proportional hazards regression models were fitted to compare the rates of failure.

Abstract

INTRODUCTION

This study aimed to examine how physical activity and health-related quality of life (HRQoL) evolved over the first year after total knee replacement (TKR) for patients with and without post-operative chronic knee pain.

METHODS

83 adults participating in the PEP-TALK, a RCT testing the effectiveness of a behaviour change physiotherapy intervention versus usual rehabilitation post-primary TKR, were analysed. UCLA Activity Score and EQ-5D-5L values for participants with and without chronic knee pain (14 points or lower in the Oxford Knee Score Pain Subscale at six months post-TKR) were compared at six and 12 months post-TKR. We evaluated recovery trajectory those with or without chronic pain at these time points.

Aims

Despite the increasing numbers of ankle arthroplasties, there are limited studies on their survival and comparisons between different implants. The primary aim of this study was to determine the failure rates of primary ankle arthroplasties commonly used in the UK.

Methods

A data linkage study combined National Joint Registry (NJR) data and NHS Digital data. The primary outcome of failure was defined as the removal or exchange of any components of the implanted device. Life tables and Kaplan-Meier survival charts were used to illustrate survivorship. Cox proportional hazards regression models were fitted to compare failure rates between 1 April 2010 and 31 December 2018.

Purpose and background

To evaluate the clinical and cost-effectiveness of a physical and psychological group intervention (BOOST programme) compared to physiotherapy assessment and advice (best practice advice [BPA]) for older adults with neurogenic claudication (NC) which is a debilitating spinal condition.

Methods and results

A randomised controlled trial of 438 participants. The primary outcome was the Oswestry Disability Index (ODI) at 12 months. Data was also collected at 6 months. Other outcomes included Swiss Spinal Stenosis Questionnaire (symptoms), ODI walking item, 6-minute walk test (6MWT) and falls. The analysis was intention-to-treat. We collected the EQ5D and health and social care use to estimate cost-effectiveness.

Participants were, on average, 74.9 years old (SD 6.0). There was no significant difference in ODI scores between groups at 12 months (adjusted mean difference (MD): −1.4 [95% Confidence Intervals (CI) −4.03,1.17]), but, at 6 months, ODI scores favoured the BOOST programme (adjusted MD: −3.7 [95% CI −6.27, −1.06]). Symptoms followed a similar pattern. The BOOST programme resulted in greater improvements in walking capacity (6MWT MD 21.7m [95% CI 5.96, 37.38]) and ODI walking item (MD −0.2 [95% CI −0.45, −0.01]) and reduced falls risk (odds ratio 0.6 [95% CI 0.40, 0.98]) compared to BPA at 12 months. Probability that the BOOST programme is cost-effective ranged from 67%–89% across cost-effectiveness thresholds.

Abstract

Introduction

This multi-centre randomised controlled trial evaluated the clinical and cost effectiveness of liposomal bupivacaine for pain and recovery following knee replacement.

Methodology

533patients undergoing primary knee replacement were randomised to receive either liposomal bupivacaine (266mg) plus bupivacaine hydrochloride (100mg) or control (bupivacaine hydrochloride 100mg), administered at the surgical site. The co-primary outcomes were pain visual analogue score (VAS) area under the curve (AUC) 6 to 72hours and the Quality of Recovery 40 (QoR-40) score at 72hours.

Aims

The increase in prescription opioid misuse and dependence is now a public health crisis in the UK. It is recognized as a whole-person problem that involves both the medical and the psychosocial needs of patients. Analyzing aspects of pathophysiology, emotional health, and social wellbeing associated with persistent opioid use after injury may inform safe and effective alleviation of pain while minimizing risk of misuse or dependence. Our objectives were to investigate patient factors associated with opioid use two to four weeks and six to nine months after an upper limb fracture.

Methods

A total of 734 patients recovering from an isolated upper limb fracture were recruited in this study. Opioid prescription was documented retrospectively for the period preceding the injury, and prospectively at the two- to four-week post-injury visit and six- to nine-month post-injury visit. Bivariate and multivariate analysis sought factors associated with opioid prescription from demographics, injury-specific data, Patient Reported Outcome Measurement Instrumentation System (PROMIS), Depression computer adaptive test (CAT), PROMIS Anxiety CAT, PROMIS Instrumental Support CAT, the Pain Catastrophizing Scale (PCS), the Pain Self-efficacy Questionnaire (PSEQ-2), Tampa Scale for Kinesiophobia (TSK-11), and measures that investigate levels of social support.

Aims

Patient engagement in adaptive health behaviours and interactions with their healthcare ecosystem can be measured using self-reported instruments, such as the Patient Activation Measure (PAM-13) and the Effective Consumer Scale (ECS-17). Few studies have investigated the influence of patient engagement on limitations (patient-reported outcome measures (PROMs)) and patient-reported experience measures (PREMs). First, we assessed whether patient engagement (PAM-13, ECS-17) within two to four weeks of an upper limb fracture was associated with limitations (the Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH), and Patient-Reported Outcome Measurement Information System Upper Extremity Physical Function computer adaptive test (PROMIS UE PF) scores) measured six to nine months after fracture, accounting for demographic, clinical, and psychosocial factors. Secondly, we assessed the association between patient engagement and experience (numerical rating scale for satisfaction with care (NRS-C) and satisfaction with services (NRS-S) six to nine months after fracture.

Methods

A total of 744 adults with an isolated fracture of the proximal humerus, elbow, or distal radius completed PROMs. Due to multicollinearity of patient engagement and psychosocial variables, we generated a single variable combining measures of engagement and psychosocial factors using factor analysis. We then performed multivariable analysis with p < 0.10 on bivariate analysis.

Aims

Outcome measures quantifying aspects of health in a precise, efficient, and user-friendly manner are in demand. Computer adaptive tests (CATs) may overcome the limitations of established fixed scales and be more adept at measuring outcomes in trauma. The primary objective of this review was to gain a comprehensive understanding of the psychometric properties of CATs compared with fixed-length scales in the assessment of outcome in patients who have suffered trauma of the upper limb. Study designs, outcome measures and methodological quality are defined, along with trends in investigation.

Materials and Methods

A search of multiple electronic databases was undertaken on 1 January 2017 with terms related to “CATs”, “orthopaedics”, “trauma”, and “anatomical regions”. Studies involving adults suffering trauma to the upper limb, and undergoing any intervention, were eligible. Those involving the measurement of outcome with any CATs were included. Identification, screening, and eligibility were undertaken, followed by the extraction of data and quality assessment using the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) criteria. The review is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria and reg

Purpose of study

To evaluate implementation of the Back Skills Training (BeST) programme in clinical practice within the National Health Service (NHS).

Background

The BeST programme is a group Cognitive Behavioural Approach (CBA) for people with persistent (≥6 weeks) low back pain (LBP). This intervention has been shown to be clinically and cost-effective in a large pragmatic trial. To aid implementation of the BeST programme, an online training intervention (iBeST) was developed.

Aims

We wished to assess the feasibility of a future randomised controlled trial of parathyroid hormone (PTH) supplements to aid healing of trochanteric fractures of the hip, by an open label prospective feasibility and pilot study with a nested qualitative sub study. This aimed to inform the design of a future powered study comparing the functional recovery after trochanteric hip fracture in patients undergoing standard care, versus those who undergo administration of subcutaneous injection of PTH for six weeks.

Patients and Methods

We undertook a pilot study comparing the functional recovery after trochanteric hip fracture in patients 60 years or older, admitted with a trochanteric hip fracture, and potentially eligible to be randomised to either standard care or the administration of subcutaneous PTH for six weeks. Our desired outcomes were functional testing and measures to assess the feasibility and acceptability of the study.

Background and Purpose

Chronic low back pain (CLBP) can be constant or episodic. Fluctuations are common. We present two different pictures of the CLBP experience; timelines illustrating back pain over time and ‘web diagrams’ showing a snapshot of a phase in time.

Methods

Semi structured interviews from 34 participants from the UK BeST trial included timelines drawn collaboratively by the researcher and participant. Symptoms, events, treatment and consultations were arranged chronologically along a timeline. Initial thematic analysis on 63 interviews gave bio-psychosocial themes that were spoken about in an integrated way. Further analysis explored these interactions between themes. Interactions were classified as; helpful to recovery, unhelpful or mixed. Web diagrams were drawn for each interview and classified as Dense- mostly unhelpful interactions, Open – a combination of helpful and unhelpful interactions and Sparse – mostly helpful interactions.

Impaired vascularity of the skin in elderly ankle fracture patients causes the skin and wound complications. This is part of a RCT comparing ORIF and close contact casting (CCC) for isolated unstable ankle fractures in patients > 60 years. Assessments over 6-months

trans-cutaneous O2 saturation (TcP02) of medial and lateral ankle skin

Ankle-Brachial Pressure Index (ABPI).

3-vessel arterial duplex scan

distal calf perforator artery patency.

The uninjured limb was the control.

Eighty-nine patients eligible; 59 participated (76% female). 30 randomised to ORIF; 29 to CCC. Each had one death and one withdrawal. Vascular data available on 55. Two patients had delays in wound healing (> 25% for > 6-weeks). Two further developed wound infections. No skin breakdowns in CCC group. There was a reduced TcP02 on day-3 in the injured limb. The TcP02 rose at 6-weeks compared to day-3 (medial 58mmHg; lateral 53mmHg, p=0.002) in the injured leg. At 6-months the TcP02 measurements were not different to uninjured leg. A critical TcP02 (< 20mmHg) found in 4, correlated with skin problems (p=0.003). Two of these had the only major delays in wound healing and one of the two wound infections.

94% of participants had normal ABPI’s (> 1.0). There was no difference between patients with or without an impaired ABPI (< 0.7 mm Hg) and wound problems (p=0.20).

There was no difference in patent perforators between the injured and uninjured (p=0.39).

Occult vascular insufficiency is present but at low incidence. ABPI and Duplex-US are insensitive for predicting infection or delayed healing. The ankle fracture injury does not disrupt the local perforators. TcPO2 is sensitive and specific for predicting skin problems. Impairment of skin oxygenation is transient. Current TcPO2 technology however is impractical as a clinical tool.

Introduction: Randomised Controlled Trials (RCTs) of interventions to reduce the incidence of falls have used a variety of methods to define and measure outcomes. A standardised approach to defining and measuring outcomes, and a shared taxonomy of interventions is a prerequisite to interpret and disseminate the findings of studies.

Method: We agreed to focus on five areas: falls, injuries, psychological consequences, physical activity and quality of life. A systematic literature review has been performed to identify outcome definitions currently used in RCTs and is focusing on the quality of outcome measures in terms of reliability, validity and acceptability. A consensus building process is being performed using a modified nominal group technique to define a core set of outcome definitions and measures, which can then be piloted in a number of sites across Europe. Where consensus cannot be achieved, suggestions are made for future research to develop and/or appraise new methods of measurement and these will feed into future revisions of the recommendations. The taxonomy of interventions is being developed in parallel with this process.

Results: The presentation will demonstrate how varying methods of defining falls can lead to a different interpretation of trial results and suggest a range of definitions than might be included in future trials. We consider the number of falls, number of fallers, time to first fall, and fractures per fall ratios as examples.

Conclusions: An agreed and standardised set of outcome definitions and measures is important to improve the robustness of data from intervention studies, will enable comparison across studies, good quality measurement in multi-centre trials, and facilitate meta-analysis of trial results. A taxonomy of interventions facilitates comparisons between studies, helps to determine the most effective components or sub-components of interventions, and aids the decision making process of policy makers and health insurance plans.
