Meta-Analysis
BACKGROUND
This systematic review and meta-analysis examined the effectiveness of orthoses for flexible flatfeet in terms of patient-reported outcomes in children and adults.
METHODS
EMBASE, Medline (OvidSP), Web-of-Science, Scopus, CINAHL, Cochrane Central Register of Controlled Clinical Trials, i.e., Cochrane Central and Pubmed were searched to identify relevant studies since their inception up to February 2021. We included randomized controlled trials (RCT) and prospective studies in which patient reported outcomes at baseline and follow-up in an orthoses group were compared with a no orthoses or sham sole group. Methodological quality of the studies was assessed using the Revised Cochrane risk-of-bias tool for randomized trials (RoB 2) and the Risk Of Bias In Non-Randomized Studies of Interventions (ROBINS-I). A meta-analysis was performed where there were multiple studies with the same outcome measures, which was the case for the Visual Analogue Scale (VAS) for pain in adults.
RESULTS
In total nine studies were included: four RCT in children (N = 353) and four RCT and one prospective study in adults (N = 268) were included. There was considerable heterogeneity between studies. A meta-analysis demonstrated that pain reduction between baseline and follow-up was significantly larger in the orthoses (N = 167) than in the control groups in adults (N = 157; - 4.76, 95% CI [- 9.46, - 0.06], p0.05).
CONCLUSION
Due to heterogeneity in study designs, we cannot conclude that foot orthoses are useful for flexible flatfoot in children and adults. However, based on the meta-analysis orthoses might be useful in decreasing pain in adults. The authors did not receive support from any organization for the submitted work.

Review
Children with obesity report musculoskeletal pain more than normal-weight children; this may be linked with literature suggesting children with obesity have higher prevalence of pes planus (flatfoot). To further elucidate whether this relation occurs, we conducted a systematic literature review on the co-occurrence of pes planus and paediatric obesity. Empirical articles published until September 2013 were obtained through an electronic search of MEDLINE and SPORTDiscus; included articles examined the association between body weight and pes planus in children. Thirteen cross-sectional studies of varied designs were identified. Methods used to diagnose pes planus varied between studies: imaging modalities, anthropometric measurements and clinical examination. Across all studies, pes planus prevalence among children with obesity ranged widely from 14 to 67%. Nearly all studies indicated increasing pes planus in children with increasing weight. No studies evaluated pain/complications related to pes planus. Our review suggests increased prevalence of pes planus among children with obesity or increasing weight status. Because of differing methodologies, lack of consensus regarding the pes planus definition, the dearth of investigation into pain/complications and the few existing studies, more research is needed to determine a relation between children's body weight, pes planus and associated effects on pain and function.

Meta-Analysis Review
STUDY DESIGN
Systematic literature review with meta-analysis.
OBJECTIVES
To investigate the association between nonneutral foot types (high arch and flatfoot) and lower extremity and low back injuries, and to identify the most appropriate methods to use for foot classification.
METHODS
A search of 5 electronic databases (PubMed, Embase, CINAHL, SPORTDiscus, and ProQuest Dissertations and Theses), Google Scholar, and the reference lists of included studies was conducted to identify relevant articles. The review included comparative cross-sectional, case-control, and prospective studies that reported qualitative/quantitative associations between foot types and lower extremity and back injuries. Quality of the selected studies was evaluated, and data synthesis for the level of association between foot types and injuries was conducted. A random-effects model was used to pool odds ratio (OR) and standardized mean difference (SMD) results for meta-analysis.
RESULTS
Twenty-nine studies were included for meta-analysis. A significant association between nonneutral foot types and lower extremity injuries was determined (OR = 1.23; 95% confidence interval [CI]: 1.11, 1.37; P<.001). Foot posture index (OR = 2.58; 95% CI: 1.33, 5.02; P<.01) and visual/physical examination (OR = 1.17; 95% CI: 1.06, 1.28; P<.01) were 2 assessment methods using distinct foot-type categories that showed a significant association with lower extremity injuries. For foot-assessment methods using a continuous scale, measurements of lateral calcaneal pitch angle (SMD, 1.92; 95% CI: 1.44, 2.39; P<.00001), lateral talocalcaneal angle (SMD, 1.36; 95% CI: 0.93, 1.80; P<.00001), and navicular height (SMD, 0.34; 95% CI: 0.16, 0.52; P<.001) showed significant effect sizes in identifying high-arch foot, whereas the navicular drop test (SMD, 0.45; 95% CI: 0.03, 0.87; P<.05) and relaxed calcaneal stance position (SMD, 0.49; 95% CI: 0.01, 0.97; P<.05) displayed significant effect sizes in identifying flatfoot. Subgroup analyses revealed no significant associations for children with flatfoot, cross-sectional studies, or prospective studies on high arch.
CONCLUSIONS
High-arch and flatfoot foot types are associated with lower extremity injuries, but the strength of this relationship is low. Although the foot posture index and visual/physical examination showed significance, they are qualitative measures. Radiographic and navicular height measurements can delineate high-arch foot effectively, with only anthropometric measures accurately classifying flatfoot.

Review
Paediatric flexible flatfoot (PFF) is a very common condition and a common concern among parents and various healthcare professionals. There is a multitude of conservative and surgical treatments, with foot orthoses (FO) being the first line of treatment due to their lack of contraindications and because the active participation of the child is not required, although the evidence supporting them is weak. It is not clear what the effect of FO is, nor when it is advisable to recommend them. PFF, if left untreated or uncorrected, could eventually cause problems in the foot itself or adjacent structures. It was necessary to update the existing information on the efficacy of FO as a conservative treatment for the reduction in signs and symptoms in patients with PFF, to know the best type of FO and the minimum time of use and to identify the diagnostic techniques most commonly used for PFF and the definition of PFF. A systematic review was carried out in the databases PubMed, EBSCO, Web of Science, Cochrane, SCOPUS and PEDro using the following strategy: randomised controlled trials (RCTs) and controlled clinical trials (CCTs) on child patients with PFF, compared to those treated with FO or not being treated, assessing the improvement of signs and symptoms of PFF. Studies in which subjects had neurological or systemic disease or had undergone surgery were excluded. Two of the authors independently assessed study quality. PRISMA guidelines were followed, and the systematic review was registered in PROSPERO: CRD42021240163. Of the 237 initial studies considered, 7 RCTs and CCTs published between 2017 and 2022 met the inclusion criteria, representing 679 participants with PFF aged 3-14 years. The interventions of the included studies differed in diagnostic criteria, types of FO and duration of treatment, among others. All articles conclude that FO are beneficial, although the results must be taken with caution due to the risk of bias of the included articles. There is evidence for the efficacy of FO as a treatment for PFF signs and symptoms. There is no treatment algorithm. There is no clear definition for PFF. There is no ideal type of FO, although all have in common the incorporation of a large internal longitudinal arch.

Review
BACKGROUND
This article addresses the treatment of pediatric flatfoot with foot orthoses and explores the existing knowledge from an evidence-based perspective.
METHODS
Studies investigating the use of foot orthoses for pediatric flatfoot were reviewed and ranked on the evidence hierarchy model according to research designs. Clinical guidelines and efficacy rating methods were also reviewed.
RESULTS
Three randomized controlled trials exist, and a systematic review and possible meta-analysis of these studies is in progress. The results of these studies, although not definitive for the use of orthoses for pediatric flatfoot, provide useful direction. Clinical guidelines for the management of flatfoot are a useful supplement for clinical decision making and have been enhanced.
CONCLUSION
This article presents a pragmatic and evidence-based clinical care pathway for clinicians to use for pediatric flatfoot. It uses a simple "traffic light" framework to identify three subtypes of pediatric flatfoot. The clinician is advised to 1) treat symptomatic pediatric flatfoot, 2) monitor (or with discretion simply treat) asymptomatic nondevelopmental pediatric flatfoot, and 3) identify and advise asymptomatic developmental pediatric flatfoot. (Children with juvenile arthritis should receive customized foot orthoses.) This approach will dispel much of the contention surrounding the use of foot orthoses in children.

Review
BACKGROUND
Posterior tibial tendon dysfunction (PTTD) and adult acquired flatfoot deformity (AAFD) are used interchangeably, although both suggest quite different pathological processes.
OBJECTIVE
To investigate key differences in selection criteria used for inclusion into research studies.
METHODS
An electronic database search was performed from inception to June 2016. All primary research articles with clear inclusion/diagnostic criteria for PTTD or AAFD were included in the review. All criteria were extracted and synthesised into one aggregate list. Frequencies of recurring criteria were calculated and reported for each stage of the conditions.
RESULTS
Of the potentially eligible papers, 148 (65%) did not specify inclusion/selection criteria for PTTD or AAFD and were excluded. Eligibility criteria were reported 82 times in the 80 included papers, with 69 descriptions for PTTD and 13 for AAFD. After synthesis of criteria from all papers, there were 18 key signs and symptoms. Signs and symptoms were considered to be those relating to tendon pathology and those relating to structural deformity. The total number of individual inclusion/diagnostic criteria ranged from 2 to 9. The majority of articles required signs of both tendon dysfunction and structural deformity (84% for AAFD and 81% for PTTD). Across both groups, the most frequently reported criteria were abduction of the forefoot (11.5% of total criteria used), the presence of a flexible deformity (10.2%) and difficulty performing a single leg heel raise (10.0%). This was largely the case for the PTTD articles, whereas the AAFD articles were more focused on postural issues such as forefoot abduction, medial arch collapse, and hindfoot valgus (each 16.7%).
CONCLUSION
As well as synthesising the available literature and providing reporting recommendations, this review has identified that many papers investigating PTTD/AAFD do not state condition-specific selection criteria and that this limits their clinical applicability. Key signs and symptoms of PTTD and AAFD appear similar, except in early PTTD where no structural deformity is present. We recommend that PTTD is the preferred terminology for the condition associated with signs of local tendon dysfunction with pain and/or swelling along the tendon and difficulty with inversion and/or single leg heel raise characterising stage I and difficulty with single leg heel raise and a flexible flatfoot deformity characterizing stage II PTTD. While AAFD may be useful as an umbrella term for acquired flatfoot deformities, the specific associated aetiology should be reported in studies to aid consolidation and implementation of research into practice.

Review
BACKGROUND
Paediatric pes planus ('flat feet') is a common childhood condition with a reported prevalence of 14%. Flat feet can result in pain and altered gait. No optimal strategy for non-surgical management of paediatric flat feet has been identified.
OBJECTIVES
To assess the effectiveness of non-surgical interventions for treatment of paediatric pes planus (flat feet).
SEARCH STRATEGY
We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, CINAHL, Index to Theses, and Dissertation Abstracts (up to June 2009).
SELECTION CRITERIA
All randomised and quasi-randomised trials of non-surgical interventions for paediatric pes planus were identified. The primary outcomes were pain reduction and adverse events; secondary outcomes included disability involving the foot, goniometric measurements, quality of life and patient comfort.
DATA COLLECTION AND ANALYSIS
Two authors independently extracted data and assessed the risk of bias of included trials.
MAIN RESULTS
Three trials involving 305 children were included in this review. Due to clinical heterogeneity, data were not pooled. All trials had potential for bias. Data from one trial (40 children with juvenile arthritis and foot pain) indicated that use of custom-made orthoses compared with supportive shoes alone resulted in significantly greater reduction in pain intensity (mean difference (MD) -1.5 points on a 10-point visual analogue scale (VAS), 95% CI -2.8 to -0.2; number need to treat to benefit (NNTB) 3, 95% CI 2 to 23), and reduction in disability (measured using the disability subscale of the Foot Function Index on a 100mm scale (MD -18.65mm, 95% CI -34.42 to -2.68mm). The second trial of seven to 11 year old children with bilateral flat feet (n = 178) found no difference in the number of participants with foot pain between custom-made orthoses, prefabricated orthoses and the control group who received no treatment. A third trial of one to five year olds with bilateral flat feet (n=129) did not report pain at baseline but reported the subjective impression of pain reduction after wearing shoes. No adverse effects were reported in the three trials.
AUTHORS' CONCLUSIONS
The evidence from randomised controlled trials is currently too limited to draw definitive conclusions about the use of non-surgical interventions for paediatric pes planus. Future high quality trials are warranted in this field. Only limited interventions commonly used in practice have been studied and there is much debate over the treatment of symptomatic and asymptomatic pes planus.

Meta-Analysis
Individuals with flatfoot have impaired proprioception owing to ligament laxity and impaired tendons, which can result in poor balance. Foot orthoses (FOs) have been reported to stimulate plantar mechanical receptors and are used to manage foot overpronation in individuals with flatfoot. However, the results of the use of FOs to improve balance are inconsistent. In this systematic review and meta-analysis, we aimed to identify and investigate the effects of FOs on balance in individuals with flatfoot. Electronic databases were searched for articles published before March 2023. Peer-reviewed journal studies that included adult participants with flexible flatfoot and reported the effects of FOs on balance were included and classified based on the study design: randomized control trials (RCT) and non-RCTs. Four RCT studies were retained, and their methodological quality was assessed (mean, 63.2%; range 47.3%-73.1%: high), as were three non-RCT studies (mean, 54.1%; range, 42.1%-68.4%: high). Meta-analysis was performed by calculating the effect size using the standardized mean differences between the control and FO conditions. Transverse-arch insoles immediately improved static balance after use. However, no immediate significant effect was found for medial archsupport FOs, cuboid-posting FOs, or University of California Berkeley Laboratory FOs during the study period (2-5 weeks) when compared with the controls. The transverse-arch insole is the most effective FO feature for improving static balance. However, the high heterogeneity between study protocols contributes to the lack of evidence for the effects of FO on balance in people with flatfoot.

Meta-Analysis Review
Flexible Adult Acquired Flatfoot is known to have multiplanar components and can often be a challenge to manage in the clinical setting, with resistance to non-surgical intervention. Lateral Column Lengthening is a favorable option for surgical management, although there are several methods in achieving this, an opening wedge osteotomy of the anterior calcaneus or distraction arthrodesis of the calcaneocuboid joint appear to be the 2 most widespread. In this review we conducted in systematic fashion, analysis of the available literature utilizing the following electronic bibliographic databases, in line with the PRISMA-P checklist: MEDLINE, CINHAL, EMBASE, and the Cochrane library without date restriction up to November 1, 2019. Results identified 21 studies which were assessed for quality using the Coleman methodology score and later evaluated using the PICO analysis system. From 172 participants, we found a higher rate of graft failure with the use of allograft versus autograft, although from a total 355 cases union rates were reported as similar. From the 355, fewer complications with arthrodesis in comparison to osteotomy were reported, including that of post-operative lateral column pain. Surgical intervention using either lateral column procedure yields excellent clinical and radiological results, the literature findings marginally favor the arthrodesis procedure and autograft over allograft. Keeping graft size under 8 mm was found to be clinically important to mitigate overlengthening of the lateral column and biomechanical testing exhibited triangular graft superiority. Where significant correction is required the addition of a medial column stabilization procedure will mitigate post-operative intractable lateral column pain.

Meta-Analysis
OBJECTIVE
It has been suggested that overweight/obesity (OW/OB) impairs the normal alignment of children and adolescents' musculoskeletal system. However, to date, no study has systematically reviewed or quantified the effect of OW/OB on the development of joint malalignments in children and adolescents. The purpose of this study was to systematically review the association between OW/OB and joint alignment in children and adolescents and to quantify the evidence on whether children and adolescents with OW/OB have a higher risk of developing joint malalignments than their peers of normal weight.
METHODS
PubMed and Web of Science databases were systematically searched from inception to March 9, 2020. Studies investigating the association between OW/OB and joint alignment in children and adolescents were selected. Nonoriginal articles, participants with movement pattern diseases, and adolescents studied while pregnant were excluded. Two independent reviewers conducted the study selection and data extraction. Qualitative synthesis of evidence and random effect meta-analyses (risk ratio [RR]) were performed.
RESULTS
Seventy-three studies (5 longitudinal and 68 cross-sectional) met the inclusion criteria involving 1,757,107 children and adolescents. There was consistent evidence supporting associations of OW/OB with rounded shoulder, lumbar hyperlordosis, genu valgum, and flatfoot. Our meta-analysis showed that children and adolescents with OW/OB had a significantly higher risk of lumbar hyperlordosis (RR = 1.41), genu valgum (RR = 5.92), flatfoot (RR = 1.49), and any joint malalignment (RR = 1.68) when compared with their peers of normal weight. The presence of genu valgum and flatfoot were the most robust results.
CONCLUSION
Based on these findings, OW/OB is associated with the presence of joint malalignments in children and adolescents.
IMPACT
This is the first study that has systematically reviewed the effect of OW/OB on the development of joint malalignments in children and adolescents.
