Early Weightbearing Versus Nonweightbearing After Operative Treatment of an Ankle Fracture: A Multicenter, Noninferiority, Randomized Controlled Trial

Rehabilitation for ankle fractures in adults

BACKGROUND

Ankle fracture is one of the most common lower limb fractures. Whilst immobilisation of the ankle can support and protect the fracture site during early healing, this also increases the risk of ankle weakness, stiffness, and residual pain. Rehabilitation aims to address the after-effects of this injury, to improve ankle function and quality of life. Approaches are wide-ranging and include strategies to improve ankle joint movement, muscle strength, or both. This is an update of a Cochrane review last published in 2012.

OBJECTIVES

To assess the effects of rehabilitation interventions following surgical or non-surgical management of ankle fractures in adults.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, three other databases, and two clinical trials registers in May 2022, and conducted additional searches of CENTRAL, MEDLINE, and Embase in March 2023. We also searched reference lists of included studies and relevant systematic reviews.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs comparing any rehabilitation intervention delivered to adults with ankle fracture. Interventions could have been given during or after the initial fracture management period (typically the first six weeks after injury), which may or may not have included surgical fixation. We excluded participants with multi-trauma, pathological fracture, or with established complications secondary to ankle fracture.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. We collected data for five outcomes: activity limitation (ankle function), health-related quality of life (HRQoL), participant satisfaction with treatment, pain, and adverse events (we focused on re-operation, defined as unplanned return to theatre). We report the findings up to six months after injury.

MAIN RESULTS

We included 53 studies (45 RCTs, 8 quasi-RCTs) with 4489 adults with ankle fracture. In most studies, orthopaedic management included surgical fixation but was non-surgical in five studies, and either surgical or non-surgical in six studies. Here, we summarise the findings for three common rehabilitation comparisons; these included the most data and were the most clinically relevant. Because of different intervention approaches, we sometimes included a study in more than one comparison. Data for other less common comparisons were also available but often included few participants and were imprecise. All studies were unavoidably at high risk of performance and detection bias. We downgraded the certainty of all evidence for this reason. We also downgraded for imprecision and when we noted inconsistencies between studies that precluded meta-analysis of data. Early (within 3 weeks of surgery) versus delayed weight-bearing (12 studies, 1403 participants) Early weight-bearing probably leads to better ankle function (mean difference (MD) 3.56, 95% confidence interval (CI) 1.35 to 5.78; 5 studies, 890 participants; moderate-certainty evidence); however, this does not include a clinically meaningful difference. Early weight-bearing may offer little or no difference to HRQoL compared to delayed weight-bearing (standardised mean difference (SMD) 0.15, 95% CI -0.01 to 0.30; 5 studies, 739 participants; low-certainty evidence); when translated to the EQ-5D scale (a commonly-used HRQoL questionnaire), any small difference was not clinically important. We were unsure whether there were any differences in participant satisfaction or pain because these outcomes had very low-certainty evidence. For adverse events, there may be little or no difference in re-operation (risk ratio (RR) 0.50, 95% CI 0.09 to 2.68; 7 studies, 1007 participants; low-certainty evidence). Removable versus non-removable ankle support (25 studies, 2206 participants) Following surgery, using a removable ankle support may lead to better ankle function (MD 6.39, 95% CI 1.69 to 11.09; 6 studies, 677 participants; low-certainty evidence). This effect included both a clinically important and unimportant difference. There is probably an improvement in HRQoL with a removable ankle support, although this difference included both a clinically important and unimportant difference when translated to the EQ-5D scale (SMD 0.30, 95% CI 0.11 to 0.50; 3 studies, 477 participants; moderate-certainty evidence). No studies reported participant satisfaction. We were unsure of the effects on pain because of very low-certainty evidence (1 study, 29 participants). There may be little or no difference in re-operations (RR 1.20, 95% CI 0.39 to 3.71; 6 studies, 624 participants; low-certainty evidence). Following non-surgical management, there may be little or no difference between removable and non-removable ankle supports in ankle function (MD 1.08, 95% CI -3.18 to 5.34; 3 studies, 399 participants), and HRQoL (SMD -0.04, 95% CI -0.24 to 0.15; 3 studies, 397 participants); low-certainty evidence. No studies reported participant satisfaction. We were unsure of the effects on pain (2 studies, 167 participants), or re-operation because of very low-certainty evidence (1 study, 305 participants). Physical therapy interventions versus usual care or other physical therapy interventions (9 studies, 857 participants) Types of interventions included the use of active controlled motion, a spring-loaded ankle trainer, an antigravity treadmill, and variations of enhanced physiotherapy (e.g. additional stretching, joint mobilisation, neuromuscular exercises), delivered during or after the initial fracture management period. We were unable to pool data because of the differences in the design of interventions and their usual care comparators. Studies often included very few participants. The certainty of the evidence for all outcomes in this comparison was very low, and therefore we were unsure of the effectiveness of these therapies. No studies in this comparison reported re-operation.

AUTHORS' CONCLUSIONS

Early weight-bearing may improve outcomes in the first six months after surgery for ankle fracture, but the difference is likely to be small and may not always be clinically important. A removable ankle support may also provide a better outcome, but again, the difference may not always be clinically important. It is likely that neither approach increases the re-operation risk. We assume that the findings for these comparisons are applicable to people with closed ankle fractures, and that satisfactory fracture stabilisation had been achieved with surgery. For people who have non-surgical treatment, there is no evidence that either a removable or non-removable ankle support may be superior. We were uncertain whether any physical therapy interventions were more effective than usual care or other physical therapy interventions. We encourage investigators of future studies on rehabilitation interventions for ankle fracture to use a core outcome set.

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. Both groups were restricted to non-weightbearing until six weeks post-surgery. The primary outcome was assessed using the Olerud-Molander Ankle Score (OMAS) questionnaire at 12 weeks post-surgery, with secondary measures at two, six, 24, and 52 weeks. Exploratory cost-effectiveness analyses were also performed.

Results

Overall, 130 participants returned their 12-week OMAS questionnaires. The mean OMAS was significantly higher in the EMADE group compared with the immobilized group (62.0 (SD 20.9) vs 48.8 (SD 22.5)), with a clinically meaningful mean difference of 13.2 (95% CI 5.66 to 20.73; p < 0.001). These differences were maintained at week 24, with convergence by week 52. No intervention-related adverse events, including instability, were reported.

Conclusion

The EMADE programme demonstrated an accelerated recovery compared to traditional six-week cast immobilization for those who have undergone ORIF surgery to stabilize Weber B (AO44B) ankle fractures. The study found the EMADE intervention to be safe.

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).

The effect of early weight-bearing and later weight-bearing rehabilitation interventions on outcomes after ankle fracture surgery: A systematic review and meta-analysis of randomised controlled trials

OBJECTIVE

This systematic review aimed to analyse the effect of early weight bearing versus late weight bearing on rehabilitation outcomes after ankle fractures, which primarily include ankle function scores, time to return to work/daily life and complication rates.

METHODS

The China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, China Science and Technology Journal, Web of Science, PubMed, Embase and Cochrane Library databases were searched. The focus was on identifying randomised controlled trials centred on early weight-bearing interventions for post-operative ankle fracture rehabilitation. All databases were searched for eligible studies published within the period from database inception to 20 June 2023. The eligible studies were screened according to the inclusion criteria. Study quality was evaluated using the methodology recommended by the Cochrane Handbook for the Systematic Evaluation of Interventions. Two authors independently performed the literature search and data extraction. Eligible studies were subjected to meta-analyses using Review Manager 5.3. Based on the time points at which post-operative ankle function was reported in the studies included in this paper, we decided to perform a meta-analysis of ankle function scores at 6 weeks post-operatively, 12 weeks post-operatively, 24-26 weeks post-operatively and 1 year post-operatively.

RESULTS

A total of 11 papers, comprising 862 patients, were included. Meta-analysis indicated that patients receiving early weight-bearing interventions, which referred to weight-bearing for 6 weeks post-operatively, experienced enhancements in ankle function scores (Olerud-Molander score, AOFAS score or Baird-Jackson score) at various post-operative milestones: 6 weeks (SMD = 0.69, 95% CI: 0.49-0.88 and p < 0.01), 12 weeks (SMD = 0.57, 95% CI: 0.22-0.92 and p < 0.01) and the 24-26 weeks range (SMD = 0.52, 95% CI: 0.20-0.85 and p < 0.01). The results of subgroup analyses revealed that the effects of early weight-bearing interventions were influenced by ankle range-of-motion exercises. Additionally, early weight bearing allows patients to return to daily life and work earlier, which was evaluated by time when they resumed their preinjury activities (MD = -2.74, 95% CI: -3.46 to -2.02 and p < 0.01), with no distinct elevation in the incidence of complications (RR = 1.49, 95% CI: 0.85-2.61 and p > 0.05).

CONCLUSION

The results showed that early weight bearing is effective in improving ankle function among post-operative ankle fracture patients and allows patients to return to daily life earlier. Significantly, the safety profile of early weight bearing remains favourable, with no higher risk of complications than late weight bearing.

To cast or not to cast? Postoperative care of ankle fractures: a meta-analysis of randomized controlled trials

Postoperative care of ankle fractures treated with open reduction and internal fixation (ORIF) is a debated topic. A meta-analysis of Randomized Controlled Trials was conducted with the aim of comparing early mobilization and weightbearing to traditional postoperative protocols. A systematic search of electronic databases was conducted according to the PRISMA guidelines. Only randomized clinical trials were included. Data about clinical outcome, time to return to work and complications were extracted and summarized. Meta-analyses were performed. Twenty studies for a total of 1328 patients were included. Early mobilization was compared to immobilization in 724 patients: the two groups did not significantly differ in terms of short- and long-term clinical outcome (p = 0.08 and p = 0.41, respectively). However, early mobilization resulted to be significantly associated with faster return to work (p = 0.047). Early weightbearing was compared to nonweightbearing in 1088 patients. While the clinical difference between the two groups was not significant at short term (p = 0.08), it was significant at long term (p = 0.002). No other significant differences, in particular regarding complications, were highlighted between different groups. Early motion, early weightbearing and traditional postoperative protocols are all safe strategies after ORIF for unstable ankle fractures. Early mobilization is significantly associated with faster return to work and early weightbearing improves long term clinical outcome.Level of evidence: I.

Early Versus Delayed Weight Bearing and Mobilization After Ankle Fracture Fixation Surgery: A Systematic Review and Meta-analysis of Randomized Controlled Trials

The purpose of this review was to determine whether there is a benefit to early weight bearing or mobilization in surgically treated ankle fractures. All randomized controlled trials that analyzed early vs delayed weight bearing and/or mobilization after an ankle surgery were included. The primary outcome measure was the pooled Olerud Molander Ankle Score 1 year postoperatively. No significant differences in ankle function were found at 1 year postoperatively between early and delayed weight bearing and mobilization. The 12-week results demonstrated superior early ankle function scores for patients who had early weight bearing. Patients who had early mobilization were at increased risk for postoperative complications. In surgically treated ankle fractures, early weight bearing resulted in improved short-term ankle function scores. [Orthopedics. 2024;47(2):71-78.].

Early Weight-bearing Following Surgical Treatment of Ankle Fractures Without Trans-syndesmotic Fixation Is Safe and Improves Short-term Outcomes

OBJECTIVES

The objective of this study was to ascertain outcome differences after fixation of unstable rotational ankle fractures allowed to weight-bear 2 weeks postoperatively compared with 6 weeks.

METHODS

DESIGN

Prospective case-control study.

SETTING

Academic medical center; Level 1 trauma center.

PATIENT SELECTION CRITERIA

Patients with unstable ankle fractures (OTA/AO:44A-C) undergoing open reduction internal fixation (ORIF) were enrolled. Patients requiring trans-syndesmotic fixation were excluded. Two surgeons allowed weight-bearing at 2 weeks postoperatively (early weight-bearing [EWB] cohort). Two other surgeons instructed standard non-weight-bearing until 6 weeks postoperatively (non-weight-bearing cohort).

OUTCOME MEASURES AND COMPARISONS

The main outcome measures included the Olerud-Molander questionnaire, the SF-36 questionnaire, and visual analog scale at 6 weeks, 3 months, 6 months, and 12 months postoperatively and complications, return to work, range of ankle motion, and reoperations at 12 months were compared between the 2 cohorts.

RESULTS

One hundred seven patients were included. The 2 cohorts did not differ in demographics or preinjury scores ( P > 0.05). Six weeks postoperatively, EWB patients had improved functional outcomes as measured by the Olerud-Molander and SF-36 questionnaires. Early weight-bearing patients also had better visual analog scale scores (standardized mean difference -0.98, 95% confidence interval [CI] -1.27 to -0.70, P < 0.05) and a greater proportion returning to full capacity work at 6 weeks (odds ratio = 3.42, 95% CI, 1.08-13.07, P < 0.05). One year postoperatively, EWB patients had improved pain measured by SF-36 (standardized mean difference 6.25, 95% CI, 5.59-6.92, P < 0.01) and visual analog scale scores (standardized mean difference -0.05, 95% CI, -0.32 to 0.23, P < 0.01). There were no differences in complications or reoperation at 12 months ( P > 0.05).

CONCLUSIONS

EWB patients had improved early function, final pain scores, and earlier return to work, without an increased complication rate compared with those kept non-weight-bearing for 6 weeks.

Safety of early weightbearing after ankle fracture fixation

PURPOSE

Patients with surgically treated ankle fractures are traditionally kept non-weightbearing for at least six weeks post-operatively; however, recent literature suggests numerous benefits of early weightbearing (EWB) before six weeks without significantly impacting long-term outcomes. This study aims to review the safety of early vs late weightbearing following ankle fracture fixation by assessing the complication rate.

METHODS

This was a single-centre retrospective study. Between 2020 and 2023, all ankle fixations that commenced weightbearing at two weeks were added to the EWB group. An equal number of similar patients with six-week non-weightbearing were added to the late weightbearing (LWB) group. Baseline characteristics, risk factors, types of fractures and any complications in the six-month post-operative period were evaluated from these cohorts.

RESULTS

In total, 459 ankle fixations were identified of which 87 patients met the criteria for the EWB group, with a further 87 added to the LWB group. There was no significant difference in age between the two groups (51.7 ± 20.1 vs 51.0 ± 15.5, respectively; p = 0.81), but more female patients and diabetics in the EWB group. Fracture types were similar between both cohorts (p = 0.51). Complication rate in the EWB group was not significantly different to the LWB group (5 vs 9, p > 0.05).

CONCLUSION

No increase in complication rate was identified by commencing weightbearing early at two weeks after ankle fixation compared to six weeks. We therefore suggest EWB if appropriate, given its associated benefits including restoration of patient independence and improved quality of life.

Early versus late weight-bearing in operatively treated ankle fractures with syndesmotic injury: A systematic review

BACKGROUND

Over the past 30 years, several studies have compared early weight-bearing versus late weight-bearing following open reduction and internal fixation of ankle fractures; however, no review strictly including patients with ankle fractures and complete syndesmotic disruption has been performed.

OBJECTIVE

The objective of this systematic review was to compare early versus late weight-bearing following surgery for ankle fracture with syndesmotic injury regarding clinical and patient-reported outcomes.

METHODS

A comprehensive search strategy was applied to the Cochrane Library, MEDLINE, Embase, CINAHL and PubMed databases from their inception to the 17th of January 2022. The articles were screened independently by two blinded reviewers. Data were extracted by one author, then cross-checked and approved by the other.

RESULTS

No comparative studies were found; therefore, studies describing either early or late weight-bearing were included. It was thus not possible to perform a meta-analysis. 11 studies and 751 patients were included. An early partial weight-bearing protocol was used in three studies (253 patients) and late in eight studies (498 patients). Functional outcomes suggested that there were no clear differences between early partial weight-bearing and late weight-bearing. The reoperation rate was 9-31% in the early group and 0-11% in the late. Similar results were seen for loss of syndesmotic reduction, malreduction, infection, and fixation failure.

CONCLUSION

Pros and cons were reported for early partial weight-bearing and late weight-bearing, but the evidence was very limited as our results were based on noncomparative studies. In the future, high-quality comparative studies focusing on functional outcomes within 6 months postoperatively are needed.

Immediate weight bearing without immobilization for operatively treated ankle fractures is safe - A systematic review

BACKGROUND

This systematic literature review compared weight bearing (WB) vs. partial- / non-weight bearing (NWB) and mobilization (MB) vs. immobilization (IMB) for surgically treated ankle fractures.

METHODS

Five databases were searched. Eligible were (quasi-)randomized controlled trials comparing at least two different postoperative treatment protocols. The risk of bias was assessed using the RoB-2 toolkit. The primary outcome was complication rate, secondary outcome Olerud and Molander Ankle Score (OMAS), range of motion (ROM), and return to work (RTW).

RESULTS

Out of 10,345 studies, 24 papers were eligible. Thirteen studies (n = 853) compared WB/NWB, 13 studies (n = 706) MB/IMB with a moderate study quality. WB did not increase the risk for complications but resulted in superior short-term outcomes for OMAS, ROM, RTW. 12 studies found no inferior results for MB compared to IMB.

CONCLUSION

Early and immediate WB and MB do not increase the complication rates but result in superior short term outcome scores.

Characteristics and Effectiveness of Postoperative Rehabilitation Strategies in Ankle Fractures: A Systematic Review

OBJECTIVES

To explore the characteristics and to report on the effectiveness of postoperative rehabilitation strategies for people with an ankle fracture.

DATA SOURCES

PubMed, Cochrane Library, EMBASE, Web of Science, and CINAHL were searched to identify studies published from January 2010 to November 2021.

STUDY SELECTION

Studies that described or evaluated postoperative rehabilitation strategies for surgically repaired ankle fractures were included.

DATA EXTRACTION

Data on postoperative rehabilitation were extracted in accordance with the Template for Intervention Description and Replication guide. Quality was assessed using the National Heart, Lung, and Blood Institute's Study Quality Assessment Tools.

DATA SYNTHESIS

Meta-analysis was planned to look at the effectiveness of postoperative rehabilitation strategies. Forty studies described postoperative rehabilitation strategies without evaluating effectiveness, whereas 15 studies focused on evaluating effectiveness. Because of the large variety in postoperative strategies and outcomes, narrative synthesis was deemed most suitable to answer our aims. Characteristics of postoperative rehabilitation strategies varied widely and were poorly described in a way that could not be replicated. Most of the studies (48%) used a late weight-bearing approach, although definitions and details around weight-bearing were unclear.

CONCLUSIONS

Late weight-bearing has been the most common postoperative approach reported in the past 10 years. The variety of definitions around weight-bearing and the lack of details of rehabilitation regimens limit replication and affect current clinical practice. The authors propose to adopt consistent definitions and terminology around postoperative practices such as weight-bearing to improve evidence for effectiveness and ultimately patient outcomes.

Early versus late weight bearing & ankle mobilization in the postoperative management of ankle fractures: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

While open reduction and internal fixation is currently considered the optimum treatment option for displaced ankle fractures, the most optimal post-operative rehabilitation strategy in this setting remains unclear. The objective of this investigation was to compare the effect of early vs. late weight bearing and ankle mobilization in the post-operative management of ankle fractures.

METHODS

Medline, Embase, CENTRAL, Scopus, CINHAL, and Web of Science were searched to identify randomized controlled trials (RCTs) and quasi-RCTs. Two review authors screened articles, abstracted data, and evaluated risk of bias in duplicate. Outcomes of interest included post-operative ankle function and overall time to return to work. Studies on weight bearing and ankle mobilization were analysed separately and all data were pooled using random-effects models.

RESULTS

Eighteen trials were included in the review of which 14 were included in the meta-analysis of at least one outcome of interest. Majority of the studies presented a high overall risk of bias. Early weight bearing demonstrated significantly better short-term postoperative functional scores at 6-9 weeks postoperatively (SMD: 0.39, 95% CI: 0.19, 0.58; p < 0.0001; I² = 0%). However, the functional effect of early weight bearing compared to late weight bearing gradually became equivalent by the 6 month postoperative time-period. Early weight bearing also demonstrated a significant reduction in the time to return to work/daily activities (MD: -12.29, 95% CI: -17.39, -7.19; p < 0.0001; I² = 0%). In comparison, no significant differences were found between early ankle mobilization/exercises and immobilization.

CONCLUSION

Our findings suggest a potential role of EWB in improving post-operative ankle-function in the short-term and reducing the overall time to return to work/daily activities, but no clinical benefit associated with early ankle mobilization post-surgery.

Ankle tibiotalocalcaneal nailing in elderly ankle fractures as an alternative to open reduction internal fixation: technique and literature review

The use of tibiotalocalcaneal nails for unstable ankle fractures in low demand elderly patients has been introduced as an alternative to open reduction internal fixation to allow early weight-bearing and to decrease soft tissue complications and mechanical failures. This paper describes the technique of hindfoot nailing and reviews the current literature. Overall, it is a minimally invasive and expeditious procedure that provides stable fixation to withstand immediate ambulation of the frail elderly patient. Future high-quality randomized controlled trials will determine if complications and outcomes compare favorably to open reduction and internal fixation.
