Early versus delayed weight-bearing following operatively treated ankle fracture (WAX): a non-inferiority, multicentre, randomised controlled trial.

BACKGROUND: After surgery for a broken ankle, patients are usually instructed to avoid walking for 6 weeks (delayed weight-bearing). Walking 2 weeks after surgery (early weight-bearing) might be a safe and preferable rehabilitation strategy. This study aimed to determine the clinical and cost effectiveness of an early weight-bearing strategy compared with a delayed weight-bearing strategy. METHODS: This was a pragmatic, multicentre, randomised, non-inferiority trial including 561 participants (aged ≥18 years) who received acute surgery for an unstable ankle fracture in 23 UK National Health Service (NHS) hospitals who were assigned to either a delayed weight-bearing (n=280) or an early weight-bearing rehabilitation strategy (n=281). Patients treated with a hindfoot nail, those who did not have protective ankle sensation (eg, peripheral neuropathy), did not have the capacity to consent, or did not have the ability to adhere to trial procedures were excluded. Neither participants nor clinicians were masked to the treatment. The primary outcome was ankle function measured using the Olerud and Molander Ankle Score (OMAS) at 4 months after randomisation, in the per-protocol population. The pre-specified non-inferiority OMAS margin was -6 points and superiority testing was included in the intention-to-treat population in the event of non-inferiority. The trial was prospectively registered with ISRCTN Registry, ISRCTN12883981, and the trial is closed to new participants. FINDINGS: Primary outcome data were collected from 480 (86%) of 561 participants. Recruitment was conducted between Jan 13, 2020, and Oct 29, 2021. At 4 months after randomisation, the mean OMAS score was 65·9 in the early weight-bearing and 61·2 in the delayed weight-bearing group and adjusted mean difference was 4·47 (95% CI 0·58 to 8·37, p=0·024; superiority testing adjusted difference 4·42, 95% CI 0·53 to 8·32, p=0·026) in favour of early weight-bearing. 46 (16%) participants in the early weight-bearing group and 39 (14%) in the delayed weight-bearing group had one or more complications (adjusted odds ratio 1·18, 95% CI 0·80 to 1·75, p=0·40). The mean costs from the perspective of the NHS and personal social services in the early and delayed weight-bearing groups were £725 and £785, respectively (mean difference -£60 [95% CI -342 to 232]). The probability that early weight-bearing is cost-effective exceeded 80%. INTERPRETATION: An early weight-bearing strategy was found to be clinically non-inferior and highly likely to be cost-effective compared with the current standard of care (delayed weight-bearing).

Advice only versus advice and a physiotherapy programme for acute traumatic anterior shoulder dislocation: the ARTISAN RCT.

Background: The extra benefit of a programme of physiotherapy in addition to advice alone, following first-time traumatic shoulder dislocation, is uncertain. We compared the clinical and cost-effectiveness of a single session of advice with a single session of advice and a programme of physiotherapy. Objective: The primary objective was to quantify and draw inferences about observed differences in the Oxford Shoulder Instability Score between the trial treatment groups 6 months post randomisation, in adults with a first-time traumatic shoulder dislocation. Design: A pragmatic, multicentre, superiority, randomised controlled trial with embedded qualitative study. Setting: Forty-one hospitals in the UK NHS. Participants: Adults with a radiologically confirmed first-time traumatic anterior shoulder dislocation, being managed non-operatively. People with neurovascular complications or bilateral dislocations, and those unable to adhere to trial procedures or unable to attend physiotherapy within 6 weeks of injury, or who had previously been randomised, were excluded. Interventions: All participants received the same initial shoulder examination followed by advice to aid self-management, lasting up to 1 hour and administered by a physiotherapist (control). Participants randomised to receive an additional programme of physiotherapy were offered sessions lasting for up to 30 minutes, over a maximum duration of 4 months from the date of randomisation (intervention). Main outcome measures: The primary outcome measure was the Oxford Shoulder Instability Score. This is a self-completed outcome measure containing 12 questions (0-4 points each), with possible scores from 0 (worst function) to 48 (best function). Measurements were collected at 6 weeks, 3 months, 6 months and 12 months by postal questionnaire; 6 months was the primary outcome time point. The primary health outcome for economic evaluation was the quality-adjusted life-year, in accordance with National Institute of Health and Care Excellence guidelines. Results: Between 14 November 2018 and 14 March 2022, 482 participants were randomised to advice (n = 240) or advice and a programme of physiotherapy (n = 242). Participants were 34% female, with a mean age of 45 years, and treatment arms were balanced at baseline. There was not a statistically significant difference in the primary outcome between advice only and advice plus a programme of physiotherapy at 6 months for the primary intention-to-treat adjusted analysis (favours physiotherapy: 1.5, 95% confidence interval -0.3 to 3.5) or at earlier 3-month and 6-week time points on the Oxford Shoulder Instability Score (0-48; higher scores indicate better function). The probability of physiotherapy being cost-effective at a willingness-to-pay threshold of £30,000 was 0.95. Conclusions: We found little difference in the primary outcome or other secondary outcomes. Advice with additional physiotherapy sessions was found likely to be cost-effective. However, small imprecise incremental costs and quality-adjusted life-years raise questions on whether it is the best use of scarce physiotherapy resources given current service demands. Limitations: Loss to follow-up was 27%; however, the observed standard deviation was much smaller than anticipated. These changes in parameters reduced the number of participants required to observe the planned target difference of four points. Our post hoc sensitivity analysis, accounting for missing data, gives similar results. Future work: Further research should be directed towards optimising self-management strategies.

The shoulder dislocates (comes out of its socket joint) when the upper end of the arm bone is forced out during an injury. This common problem occurs mostly in men in their 20s and women aged over 80. After the bone is put back in its socket, most people are managed with physiotherapy. In the United Kingdom, once the bone is back in its socket, there is a range of physiotherapy provision: some hospitals offer advice, and some offer advice and a course of additional physiotherapy sessions. We compared advice alone to advice and physiotherapy for people who had a shoulder that had come out of its joint for the first time. Physiotherapy advice and additional sessions included education about the injury and exercises to move and strengthen the shoulder. When we started this project, this was the first time these two treatments had been compared. Our aim was to compare what activities the two groups could do 6 months after injury via a questionnaire. We also compared quality of life and the cost of rehabilitation at 6 weeks, 3 months, 6 months and 12 months after injury. Adults with a shoulder out of its joint and who were not having surgery were asked to take part. All adults who were eligible and consented to take part were assigned, by chance, to either a single session of advice or the same session followed by physiotherapy. Between 14 November 2018 and 14 March 2022 we collected data on 482 people, from 41 NHS sites across the UK. We found at 6 months there was little evidence that additional physiotherapy was better, when compared to advice alone. Cost-effectiveness analysis (comparing changes in costs and quality of life) suggests additional physiotherapy might provide value for money. However, the changes involved are small and uncertain.

Acute rehabilitation following traumatic anterior shoulder dislocation (ARTISAN): pragmatic, multicentre, randomised controlled trial.

OBJECTIVE: To assess the effects of an additional programme of physiotherapy in adults with a first-time traumatic shoulder dislocation compared with single session of advice, supporting materials, and option to self-refer to physiotherapy. DESIGN: Pragmatic, multicentre, randomised controlled trial (ARTISAN). SETTING AND PARTICIPANTS: Trauma research teams at 41 UK NHS Trust sites screened adults with a first time traumatic anterior shoulder dislocation confirmed radiologically, being managed non-operatively. People were excluded if they presented with both shoulders dislocated, had a neurovascular complication, or were considered for surgical management. INTERVENTIONS: One session of advice, supporting materials, and option to self-refer to physiotherapy (n=240) was assessed against the same advice and supporting materials and an additional programme of physiotherapy (n=242). Analyses were on an intention-to-treat basis with secondary per protocol analyses. MAIN OUTCOME MEASURES: The primary outcome was the Oxford shoulder instability score (a single composite measure of shoulder function), measured six months after treatment allocation. Secondary outcomes included the QuickDASH, EQ-5D-5L, and complications. RESULTS: 482 participants were recruited from 40 sites in the UK. 354 (73%) participants completed the primary outcome score (n=180 allocated to advice only, n=174 allocated to advice and physiotherapy). Participants were mostly male (66%), with a mean age of 45 years. No significant difference was noted between advice compared with advice and a programme of physiotherapy at six months for the primary intention-to-treat adjusted analysis (between group difference favouring physiotherapy 1.5 (95% confidence interval -0.3 to 3.5)) or at earlier three month and six week timepoints. Complication profiles were similar across the two groups (P>0.05). CONCLUSIONS: An additional programme of current physiotherapy is not superior to advice, supporting materials, and the option to self-refer to physiotherapy.

Cost-utility analysis of cast compared to removable brace in the management of adult patients with ankle fractures.

AIMS: To compare the cost-utility of removable brace compared with cast in the management of adult patients with ankle fracture. METHODS: A within-trial economic evaluation conducted from the UK NHS and personnel social services (PSS) perspective. Health resources and quality-of-life data were collected as part of the Ankle Injury Rehabilitation (AIR) multicentre, randomized controlled trial over a 12-month period using trial case report forms and patient-completed questionnaires. Cost-utility analysis was estimated in terms of the incremental cost per quality adjusted life year (QALY) gained. Estimate uncertainty was explored by bootstrapping, visualized on the incremental cost-effectiveness ratio plane. Net monetary benefit and probability of cost-effectiveness were evaluated at a range of willingness-to-pay thresholds and visualized graphically. RESULTS: The incremental cost and QALYs of using brace over a 12-month period were £46.73 (95% confidence interval (CI) £-9 to £147) and 0.0141 (95% CI -0.005 to 0.033), respectively. The cost per QALY gained was £3,318. The probability of brace being cost-effective at a £30,000 per QALY willingness-to-pay threshold was 88%. The results remained robust to a range of sensitivity analyses. CONCLUSION: This within-trial economic evaluation found that it is probable that using a removable brace provides good value to the NHS when compared to cast, in the management of adults with ankle fracture.

Development of a single-session physiotherapy and self-management intervention for the treatment of primary traumatic anterior shoulder dislocation for the 'Acute Rehabilitation following Traumatic anterior shoulder dISlocAtioN (ARTISAN)' multi centre RCT.

OBJECTIVE: Optimum physiotherapy management for people with a conservatively managed primary traumatic anterior shoulder dislocation is not known. The purpose of the ARTISAN trial is to compare the clinical and cost-effectiveness of a course of usual care physiotherapy with a single session of physiotherapy and self-management, the ARTISAN intervention. ARTISAN is a UK multi-centre, two-arm, parallel group, randomised controlled trial with 1:1 treatment allocation. DESIGN: The intervention was developed following the Medical Research Council framework for developing and evaluating complex interventions and will be reported in line with the template for intervention description and replication checklist (TIDieR) and the Consensus on Exercise Reporting Template (CERT). It was informed by published research, national clinical guidelines, current clinical practice and patient and public involvement. RESULTS: The ARTISAN intervention comprises education (Phase 1), progressive exercise (Phase 2 and Phase 3) and an optional return to sport component (Phase 4). Behaviour change strategies are embedded throughout intervention. The single session of physiotherapy is delivered by a chartered physiotherapist, within the first six weeks of injury, in an NHS outpatient setting. At the end of the initial session, paper-based booklets and/or a patient website with the same content are provided to participants to aid self-management and progression though the four phases of the trial intervention. CONCLUSION: The ARTISAN intervention was successfully implemented throughout the internal pilot and is suitable for testing in the subsequent definitive RCT ARTISAN trial. Trial Registration Number ISRCTN63184243.

Protocol for a randomised controlled trial of Subacromial spacer for Tears Affecting Rotator cuff Tendons: a Randomised, Efficient, Adaptive Clinical Trial in Surgery (START:REACTS).

INTRODUCTION: Shoulder pain due to irreparable rotator cuff tears can cause substantial disability, but treatment options are limited. A balloon spacer is a relatively simple addition to a standard arthroscopic debridement procedure, but it is costly and there is no current randomised trial evidence to support its use. This trial will evaluate the clinical and cost-effectiveness of a subacromial balloon spacer for individuals undergoing arthroscopic debridement for irreparable rotator cuff tears.New surgical procedures can provide substantial benefit to patients. Good quality randomised controlled trials (RCTs) are needed, but trials in surgery are typically long and expensive, exposing patients to risk and the healthcare system to substantial costs. One way to improve the efficiency of trials is with an adaptive sample size. Such methods are well established in drug trials but have rarely, if ever, been used in surgical trials. METHODS AND ANALYSIS: Subacromial spacer for Tears Affecting Rotator cuff Tendons: a Randomised, Efficient, Adaptive Clinical Trial in Surgery (START:REACTS) is a participant and assessor blinded, adaptive, multicentre RCT comparing arthroscopic debridement with the InSpace balloon (Stryker, USA) to arthroscopic debridement alone for people with a symptomatic irreparable rotator cuff tear. It uses a group sequential adaptive design where interim analyses are performed using all of the 3, 6 and 12-month data that are available at each time point. A maximum of 221 participants will be randomised (1:1 ratio), this will provide 90% power (at the 5% level) for a 6 point difference in the primary outcome; the Oxford Shoulder Score at 12 months. A substudy will use deltoid-active MRI scans in 56 participants to assess the function of the balloon. Analysis will be on an intention-to-treat basis and reported according to principles established in the Consolidated Standards of Reporting Trials statement. ETHICS AND DISSEMINATION: NRES number 18/WM/0025. The results will be disseminated via peer-reviewed publications, presentations at conferences, lay summaries and social media. TRIAL REGISTRATION NUMBER: ISRCTN17825590.

Plaster cast versus functional brace for non-surgical treatment of Achilles tendon rupture (UKSTAR): a multicentre randomised controlled trial and economic evaluation.

BACKGROUND: Patients with Achilles tendon rupture who have non-operative treatment have traditionally been treated with immobilisation of the tendon in plaster casts for several weeks. Functional bracing is an alternative non-operative treatment that allows earlier mobilisation, but evidence on its effectiveness and safety is scarce. The aim of the UKSTAR trial was to compare functional and quality-of-life outcomes and resource use in patients treated non-operatively with plaster cast versus functional brace. METHODS: UKSTAR was a pragmatic, superiority, multicentre, randomised controlled trial done at 39 hospitals in the UK. Patients (aged ≥16 years) who were being treated non-operatively for a primary Achilles tendon rupture at the participating centres were potentially eligible. The exclusion criteria were presenting more than 14 days after injury, previous rupture of the same Achilles tendon, or being unable to complete the questionnaires. Eligible participants were randomly assigned (1:1) to receive a plaster cast or functional brace using a centralised web-based system. Because the interventions were clearly visible, neither patients nor clinicians could be masked. Participants wore the intervention for 8 weeks. The primary outcome was patient-reported Achilles tendon rupture score (ATRS) at 9 months, analysed in the modified intention-to-treat population (all patients in the groups to which they were allocated, excluding participants who withdrew or died before providing any outcome data). The main safety outcome was the incidence of tendon re-rupture. Resource use was recorded from a health and personal social care perspective. The trial is registered with ISRCTN, ISRCTN62639639. FINDINGS: Between Aug 15, 2016, and May 31, 2018, 1451 patients were screened, of whom 540 participants (mean age 48·7 years, 79% male) were randomly allocated to receive plaster cast (n=266) or functional brace (n=274). 527 (98%) of 540 were included in the modified intention-to-treat population, and 13 (2%) were excluded because they withdrew or died before providing any outcome data. There was no difference in ATRS at 9 months post injury (cast group n=244, mean ATRS 74∙4 [SD 19∙8]; functional brace group n=259, ATRS 72∙8 [20∙4]; adjusted mean difference -1∙38 [95% CI -4∙9 to 2∙1], p=0·44). There was no difference in the rate of re-rupture of the tendon (17 [6%] of 266 in the plaster cast group vs 13 [5%] of 274 in the functional brace group, p=0·40). The mean total health and personal social care cost was £1181 for the plaster cast group and £1078 for the functional bract group (mean between-group difference -£103 [95% CI -289 to 84]). INTERPRETATION: Traditional plaster casting was not found to be superior to early weight-bearing in a functional brace, as measured by ATRS, in the management of patients treated non-surgically for Achilles tendon rupture. Clinicians may consider the use of early weight-bearing in a functional brace as a safe and cost-effective alternative to plaster casting.

Plaster cast versus functional bracing for Achilles tendon rupture: the UKSTAR RCT.

BACKGROUND: Achilles tendon rupture affects > 11,000 people each year in the UK, leading to prolonged periods away from work, sports and social activities. Traditionally, the ruptured tendon is held still in a plaster cast for ≥ 8 weeks. Functional bracing is an alternative treatment that allows patients to mobilise earlier, but there is little evidence about how bracing affects patients' recovery. OBJECTIVES: To measure the Achilles Tendon Rupture Score, quality of life, complications and resource use of patients receiving non-operative treatment for an Achilles tendon rupture treated with plaster cast compared with those treated with functional bracing. DESIGN: This was a multicentre, randomised, pragmatic, two-group superiority trial. SETTING: The setting was 39 NHS hospitals. PARTICIPANTS: A total of 540 adult patients treated non-operatively for Achilles tendon rupture were randomised from July 2016 to May 2018. Exclusion criteria included presenting after 14 days, having had previous rupture and being unable to complete questionnaires. INTERVENTIONS: A total of 266 participants had a plaster cast applied, with their toes initially pointing to the floor. The cast was changed over 8 weeks to bring the foot into a walking position. A total of 274 patients had a functional brace that facilitated immediate weight-bearing. The foot position was adjusted within the brace over the same 8-week period. MAIN OUTCOME MEASURES: Achilles Tendon Rupture Score is patient reported and assesses symptoms and physical activity related to the Achilles tendon (score 0-100, with 100 being the best possible outcome). The secondary outcomes were quality of life, complications and resource use at 8 weeks and at 3, 6 and 9 months. RESULTS: Participants had a mean age of 48.7 years, were predominantly male (79%) and had ruptured their tendon during sports (70%). Over 93% of participants completed follow-up. There was no statistically significant difference in Achilles Tendon Rupture Score at 9 months post injury (-1.38, 95% confidence interval -4.9 to 2.1). There was a statistically significant difference in Achilles Tendon Rupture Score at 8 weeks post injury in favour of the functional brace group (5.53, 95% confidence interval 2.0 to 9.1), but not at 3 or 6 months post injury. Quality of life showed the same pattern, with a statistically significant difference at 8 weeks post injury but not at later time points. Complication profiles were similar in both groups. Re-rupture of the tendon occurred 17 times in the plaster cast group and 13 times in the functional brace group. There was no difference in resource use. CONCLUSIONS: This trial provides strong evidence that early weight-bearing in a functional brace provides similar outcomes to traditional plaster casting and is safe for patients receiving non-operative treatment of Achilles tendon rupture. The probability that functional bracing is cost-effective exceeds 95% for the base-case imputed analysis, assuming a cost-effectiveness threshold of £20,000 per quality-adjusted life-year. On average, functional brace is associated with lower costs (-£103, 95% confidence interval -£290 to £84) and more quality-adjusted life-years (0.015, 95% confidence interval -0.0013 to 0.030) than plaster cast. LIMITATIONS: Some patients declined to participate in the trial, but only a small proportion of these declined because they had a preference for one treatment or another. Overall, 58% of eligible patients agreed to participate, so the participants are broadly representative of the population under investigation. FUTURE WORK: Although the UK Study of Tendo Achilles Rehabilitation provides guidance with regard to early management, rehabilitation following Achilles tendon rupture is prolonged and further research is required to define the optimal mode of rehabilitation after the initial cast/brace has been removed. TRIAL REGISTRATION: Current Controlled Trials ISRCTN62639639.

See the NIHR Journals Library website for further project information.

WHAT DID THE TRIAL FIND?: Patients recovered steadily after their injury but were still not back to normal at 9 months. The average Achilles Tendon Rupture Score rose from 38 out of 100 at 8 weeks to 73 out of 100 at 9 months. Patents who had the functional brace reported that their recovery was a little better at 8 weeks than did the patients having the plaster cast, but there was no evidence of a difference after that. There were 17 cases of re-rupture of the Achilles tendon in the plaster cast group and 13 cases in the functional brace group. There was no evidence of a difference in costs. In conclusion, this study provides strong evidence that early weight-bearing in a functional brace provides similar outcomes to traditional plaster casting and is safe for patients having treatment for Achilles tendon rupture.

Achilles tendon rupture affects > 11,000 people each year in the UK, leading to prolonged periods away from work, sports and social activities. Traditionally, after a ruptured tendon, the foot and ankle are held still in a plaster cast for ≥ 8 weeks. Functional bracing is an alternative treatment that allows patients to mobilise earlier, but there is little evidence about how it affects later recovery. This study aimed to compare traditional plaster casting with functional bracing for adult patients with Achilles tendon rupture. The participants reported their own recovery using the Achilles Tendon Rupture Score, which consists of 10 questions about symptoms and physical activity (in which a score of 100 is the best possible outcome). We also recorded quality of life, complications, including re-rupture of the tendon, and costs from both the NHS and the patients' perspective. A total of 540 patients, treated at 39 hospitals, agreed to take part and were assigned by chance to either plaster cast or functional brace. Patients reported their recovery at 8 weeks and at 3, 6 and 9 months.

Cast versus functional brace in the rehabilitation of patients treated for an ankle fracture: protocol for the UK study of ankle injury rehabilitation (AIR) multicentre randomised trial.

INTRODUCTION: Each year in the UK over 120 000 people fracture their ankle. It is not known what the best rehabilitation strategy is for these people. Traditionally standard care has involved immobilisation in a plaster cast but an alternative is a functional brace, which can be removed to allow early movement. This paper details the protocol for a multicentre randomised trial of plaster cast immobilisation versus functional bracing for patients with an ankle fracture. METHODS AND ANALYSIS: We will recruit adults with a fractured ankle, for which the treating clinician would consider plaster cast to be a reasonable management option. Randomisation will be on a 1:1 basis, stratified by centre, operative or non-operative management and age. Participants will be allocated to either plaster cast or a functional brace, both treatments are widely used. To have 90% power to detect a difference of 10 points on the primary outcome (Olerud and Molander Ankle Score) at the primary outcome time point (16 weeks), we need to randomise a minimum of 478 people. Quality of life and resource use will be collected at 6, 10, 16, 24 weeks and 12, 18, 24 months. The differences between treatment groups will be assessed on an intention-to-treat basis. The economic evaluation will adhere to the recommendations of the National Institute for Health and Care Excellence reference case. ETHICS, REGISTRATION AND DISSEMINATION: National Research Ethic Committee approved this study on 4 July 2017 (17/WM/0239). The first site opened to recruitment 9 October 2017. The results of this trial will be submitted to a peer-reviewed journal and will inform clinical practice. TRIAL REGISTRATION NUMBER: ISRCTN15537280; Pre-results.

Cast versus functional brace in the rehabilitation of patients treated non-operatively for a rupture of the Achilles tendon: protocol for the UK study of tendo achilles rehabilitation (UK STAR) multi-centre randomised trial.

INTRODUCTION: Achilles tendon rupture affects over 11 000 people yearly in the UK, and the incidence is increasing. Controversy remains with regard to the best rehabilitation strategy for these patients. In operatively treated patients, functional bracing provides better outcomes compared with plaster casts. However, the role of functional bracing in non-operatively managed patients is unclear. This is the protocol for a multicentre randomised trial of plaster cast immobilisation versus functional bracing for patients with a non-operatively managed Achilles tendon rupture. METHODS AND ANALYSIS: All adults presenting with a primary rupture of the Achilles tendon will be screened. Non-operatively treated patients will be eligible to take part in the trial. Broad eligibility criteria will ensure that the results of the study can be generalised to the wider patient population. Randomisation will be on a 1:1 basis. Both rehabilitation strategies are widely used within the National Health Service. Standardised protocols will be followed, and details of plaster material and brace will be as per the site's usual practice.A minimum of 330 patients will be randomised to obtain 90% power to detect a difference of 8 points in Achilles Tendon Total Rupture Score at 9 months. Quality of life and resource use will be collected at 3, 6 and 9 months. The differences between treatment groups will be assessed on an intention-to-treat basis. The results of the trial-based economic evaluation will be expressed in terms of incremental cost per quality-adjusted life-year gained. ETHICS AND DISSEMINATION: The National Research Ethic Committee approved this study on 18 March 2016 (16/SC/0109).The National Institute for Health Research Health Technology Assessment monograph and a manuscript to a peer-reviewed journal will be submitted on completion of the trial (summer 2019). The results of this trial will substantially inform clinical practice on the clinical and cost-effectiveness of the treatment of this injury. This study has been registered on the International Standard Randomised Controlled Trial Number registry with reference no ISRCTN62639639.
