Wijnands SDN, Grin L, van Dijk LS, Besselaar AT, van der Steen MC, Vanwanseele B. Clubfoot patients show more anterior-posterior displacement during one-leg-standing and less ankle power and plantarflexor moment during one-leg-hopping than typically developing children. Gait Posture 2024; 108:361-366. [PMID: 38227996 DOI: 10.1016/j.gaitpost.2024.01.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 01/09/2024] [Accepted: 01/10/2024] [Indexed: 01/18/2024]
Abstract
BACKGROUND Clubfoot patients show good-to-excellent foot correction after the Ponseti method. Nevertheless, underlying functional problems that limit motor abilities such as one-leg-standing and one-leg-hopping still persist. These restrictions have been proposed to arise due to problems with maintaining balance and the limited force-generating capacity of clubfoot patients. More insight is needed to understand the underlying limiting factors to improve overall motor ability in clubfoot patients. RESEARCH QUESTION The aim of this study was to determine the differences between clubfoot patients and typically developing children (TDC) in force and balance parameters during walking, one-leg-standing and hopping. METHODS Three-dimensional motion analysis was performed in 19 TDC and 16 idiopathic Ponseti-treated clubfoot patients between 5-9 years old. Kinematic and kinetic parameters were calculated during walking and one-leg-hopping. To describe the balance parameters, center of pressure (CoP) data was assessed during walking, one-leg-hopping and one-leg-standing. Mean group values were calculated and compared using nonparametric statistical tests. A general linear model with repeated measures was used to determine which activity showed the largest group differences. RESULTS Clubfoot patients showed lower peak plantarflexor moment and peak ankle power absorption and generation during one-leg-hopping compared to TDC. Furthermore, clubfoot patients showed a lower hop length and velocity than TDC. The difference in peak plantarflexor moment and ankle power between the study groups was larger during one-leg-hopping than during walking. Finally, clubfoot patients showed a higher anterior-posterior CoP range during one-leg-standing. SIGNIFICANCE Deviations in force parameters seemed to limit one-leg-hopping in clubfoot patients, and impaired anterior-posterior static balance was thought to be the underlying cause of problems with one-leg-standing. Furthermore, one-leg-hopping was more sensitive to distinguish between clubfoot patients and TDC than walking. Individualized physiotherapy targeting static balance and force parameters, with extra emphasis on including eccentric contractions, might improve the overall motor abilities of clubfoot patients.

Kinematic Gait Impairments in Children with Clubfeet Treated by the Ponseti Method: A Systematic Review and Meta-Analysis. CHILDREN (BASEL, SWITZERLAND) 2023; 10:children10050785. [PMID: 37238333 DOI: 10.3390/children10050785] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Revised: 04/20/2023] [Accepted: 04/23/2023] [Indexed: 05/28/2023]
Abstract
BACKGROUND Being aware of possible gait impairments in Ponseti-treated clubfoot children might be useful for optimizing initial and additional treatment. Therefore, this systematic review and meta-analysis aimed to identify kinematic gait abnormalities in children with clubfoot treated with the Ponseti method (with and without relapse). METHODS A systematic search was conducted. Studies comparing kinematic gait parameters of Ponseti-treated clubfoot children to healthy controls were included. Meta-analyses and qualitative analyses were conducted on the extracted data. RESULTS Twenty studies were identified. Twelve of the 153 reported kinematic outcome measures could be included in the meta-analysis. Plantarflexion at push-off, maximum ankle dorsiflexion during the swing, maximal plantarflexion, and ankle range of motion was significantly lower in Ponseti-treated clubfoot children. Ponseti-treated clubfoot children showed more internal foot progression. Qualitative analysis revealed 51 parameters in which pre-treatment relapse clubfeet deviated from healthy controls. CONCLUSIONS Ponseti-treated clubfoot children showed several kinematic gait differences from healthy controls. In future studies, homogeneity in measured variables and study population and implementation of multi-segmental foot models will aid in comparing studies and understanding clubfoot complexity and treatment outcomes. The question remains as to what functional problems gait impairments lead to and whether additional treatment could address these problems.

Abstract
BACKGROUND Relapse rates of clubfoot deformity after initial correction range between 19% and 68% regardless of treatment approach. Most studies focus on relapse before age 4. Little research has focused on late clubfoot relapse. The purpose of this study was to compare the gait characteristics of children with late clubfoot relapse (age ≥5 y) following treatment with the Ponseti method only compared with intra-articular and extra-articular surgeries. METHODS A retrospective review was conducted of all patients with idiopathic clubfoot ≥5 years old who underwent computerized gait analysis for clubfoot relapse between 2001 and 2021. Joint range of motion, muscle strength, gait kinematics, and kinetics were compared among 3 groups based on prior clubfoot treatment: (1) Ponseti casting, (2) Extra-articular (EA) surgery, and (3) Intra-articular (IA) surgery. RESULTS Sixty-eight subjects (107 feet) were included (39 bilateral). Thirty-one percent of feet had been treated with Ponseti casting alone; 57% had IA surgery, and 12% had EA surgery. The average age when presenting with late relapse was 8.2 years, 9.0 years and 10.7 years for the Ponseti, and IA and EA groups, respectively. The IA group had greater passive dorsiflexion than the other 2 groups (P<0.002), greater inversion weakness than the other 2 groups (P<0.0001), greater dorsiflexion during the stance phase of gait compared with the Ponseti group (P=0.001), and lower maximum power production at push-off compared with the other 2 groups (P=0.009). CONCLUSION Late relapse can occur after all types of clubfoot correction. Consistent with existing literature, patients who have undergone posteromedial release surgery have significantly greater plantarflexor weakness resulting in poorer plantarflexor moment and power production during gait. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
Percutaneous scalpel tenotomy is frequently performed as part of congenital talipes equinovarus (CTEV) to correct the equinus deformity. The use of a scalpel is associated with complications such as neurovascular bundle damage and pseudoaneurysms. In the literature, a percutaneous large-bore needle has been found to be a safer alternative to a scalpel for performing tenotomies. The goal of this study was to conduct a systematic review and report a single-center case series on the use of percutaneous needle tenotomy in the treatment of CTEV. A Preferred Reporting Items of Systematic Review and Meta-analysis (PRISMA)-compliant literature search was conducted to identify studies describing the use of a percutaneous needle tenotomy in the treatment of idiopathic CTEV. A retrospective case series of patients with idiopathic CTEV treated with percutaneous needle tenotomy over a seven-year period from a single center were also conducted. The patients' demographics, the location of the clubfoot, and the Pirani score were all recorded. An analysis of descriptive statistics was carried out. Continuous data were expressed as mean and SD, whereas categorical variables were expressed as absolute numbers and percentages (%). The systematic review included eight papers with a total of 1026 feet and a mean age of 10.4 weeks (SD 5.9). There were 47 (0.04%) complications across all studies, with a pooled success rate of 95%. Eleven patients (16 feet) were included in the single-center case study. The patients' initial Pirani score was 4.8 (SD 1.5), with a final score of 0. (SD 0). Four complications occurred in the patient's cohort - one minor bleeding and three recurrences as a result of poor compliance with the post-tenotomy foot abduction brace. In conclusion, the percutaneous Achilles tenotomy of a CTEV foot with a large bore needle is a safe and effective alternative.

Abstract
This study was aimed to evaluate the kinetics and kinematics of the foot and ankle using three-dimensional gait analysis in children with recurrent clubfoot treated with tibialis anterior tendon transfer (TATT). Three-dimensional gait analysis of 17 children with dynamic supination (24 feet; 12 males; mean age: 6.34 years) was performed pre- and post-TATT. Spatial, temporal and kinematic parameters, as well as the gait deviation index (GDI), were recorded for all patients. Moreover, to evaluate the severity of dynamic supination during walking, we also measured the angle between the plane of the foot and the X-axis during the swing phase (V-angle-S). The postoperative step length (38.95 ± 8.36 cm) and stride length (76.73 ± 15.92 cm) were significantly smaller than their preoperative values (40.68 ± 9.35 cm and 80.57 ± 17.51 cm; P = 0.0316 and P = 0.0028, respectively). The postoperative peak internal ankle rotation angle in the frontal plane (20.45° ± 14.44) was significantly lower than the preoperative value (25.93° ± 9.84; P = 0.029). The postoperative peak internal foot progression angle in the transverse plane (0.96° ± 5.83) was significantly lower than the preoperative value (4.34° ± 8.88; P = 0.026). However, both the peak ankle varus moment and GDI were not significantly different between the pre- and postoperative data. Postoperative V-angle-S values (28.55° ± 7.56) were reduced compared to their preoperative values (32.52° ± 6.53; P = 0.0094). TATT to the lateral cuneiform can correct dynamic supination in patients with a recurrent clubfoot; however, it has limited or no effects on hindfoot varus deformity. Level of evidence: Level III.

Abstract
Managing complications of clubfoot deformities can be very challenging. Some patients present with recurrent clubfoot and residual symptoms, and some present with overcorrection leading to a severe complex flatfoot deformity. Both can lead to long-term degenerative changes of the foot and ankle joints owing to deformity caused by unbalanced loading. This article only focuses on severe complications caused by recurrence and overcorrection in both children and adult patients.

Abstract
PURPOSE To establish parameters and propose a radiographic classification for foot adduction/supination deformities to assist the indication of Garceau procedure. Secondly, to investigate whether the outcome of Garceau surgery depends on the initial treatment used, peritalar release, or the Ponseti method, and verify the maintenance of correction until skeletal maturity. METHODS Prospective cohort study, with follow-up evaluations in 2009 and 2019. Fifty-three consecutive patients (71 feet) with idiopathic congenital clubfoot (ICCF) were divided into two groups according to the initial treatment used: peritalar release (group I) or Ponseti method (group II). All patients underwent Garceau procedure. The patients were evaluated clinically and radiographically using the American Orthopedic Foot Association (AOFAS) score for ankle and hindfoot. A radiographic classification is proposed based on the adduction by talo-first metatarsal angle on dorsoplantar view and supination by the elevation of the head of the first metatarsal on lateral view, both weight-bearing. RESULTS In the first clinical evaluation, the mean score on the AOFAS was 87 points in group I and 86 points in group II. In the second evaluation, group I had mean AOFAS of 92 points and group II of 94 points. No statistical differences were found between the two groups, neither between the first and the second evaluation. In the radiographic evaluation, the adduction deformity obtained an average correction of 4° in group I and 3.6° in group II; in supination deformity, the average depression of the first metatarsal head in relation to the ground was 6.7 mm in group I and 7.5 mm in group II, with no statistical difference between the two evaluations, indicating the correction was maintained until skeletal maturity. CONCLUSION Garceau transfer is capable of correcting residual deformities in adduction/supination of mild and moderate degrees, regardless of the initial treatment, and maintaining the correction until skeletal maturity. The proposed radiographic classification might help to objectively indicate the surgical procedure.

Abstract
Sensor based brace is a new technology driven initiative to address the adherence issues associated with clubfoot treatment. It encompasses various engineering fields (sensors, batteries, data transfer) to measure precise brace wear timings. Still in preliminary usage, yet they have lead to several significant findings; foremost being that caretakers tend to over report their brace usage. Enhanced surveillance and reinforcements is thus possible with sensor devices as defaulters can be picked up early. The introduction of these devices in common practice is postulated to lessen relapse rates by upto 40%. However, many challenges obscure the path of newer braces. Robust study designs and longer follow up is lacking in majority of studies detailing sensor based clubfoot braces. None of the currently available studies demonstrate effectiveness of patient interventions/changes based on the research data. Behavioral changes in caretakers may be difficult to achieve and could require repeated reinforcements. Since braces need to be worn for prolonged periods in clubfoot treatment, sensor data generated per patient would be colossal. It's processing and interpretation would be an uphill task. The cost of advanced inventory may burden ongoing clubfoot care programmes in low income countries. There is also a possibility that the newer technology may tone up the bracing protocol into a highly sophisticated and supervised medical intervention rather than a simplified maintenance phase. Till further development and evidence, sensor based clubfoot braces may find their initial application for high risk groups susceptible to relapse.

Abstract
BACKGROUND In 2010, 2 authors of this current study reported the results of Ponseti treatment compared with primary posteromedial release (PMR) for congenital talipes equinovarus in a cohort of 51 prospective patients. This current study shows outcomes recorded at a median of 15 years after the original treatment. METHODS Patient health records were available for all 51 patients at a median of 15 years (range, 13 to 17 years) following treatment of congenital talipes equinovarus with either the Ponseti method (25 patients [38 feet]) or PMR (26 patients [42 feet]). Thirty-eight of 51 patients could be contacted, and 33 patients (65%) participated in the clinical review, comprising patient-reported outcomes, clinical examination, 3-dimensional gait analysis, and plantar pressures. RESULTS Sixteen (42%) of 38 Ponseti-treated feet and 20 (48%) of 42 PMR-treated feet had undergone a further surgical procedure. The PMR-treated feet were more likely to undergo osteotomies and intra-articular surgical procedures (15 feet) than the Ponseti-treated feet (5 feet) (p < 0.05). Of the 33 patients reviewed with multimodal assessment, the Ponseti group, compared with the PMR group, demonstrated better Dimeglio scores (5.8 compared with 7.0 points; p < 0.05), Disease Specific Instrument (80.7 compared with 65.6 points; p < 0.05), Functional Disability Inventory (1.1 compared with 5.1; p < 0.05), and American Academy of Orthopaedic Surgeons (AAOS) Foot and Ankle Outcomes Questionnaire scores (52.2 compared with 46.6 points; p < 0.05), as well as improved total sagittal ankle range of motion in gait and ankle plantar flexion range at toe-off. The PMR group with clinical hindfoot varus displayed higher pressures in the lateral midfoot and the forefoot. CONCLUSIONS Although the numbers of repeat surgical interventions following Ponseti treatment and primary PMR were similar, the PMR-treated feet had greater numbers of osteotomies and intra-articular surgical procedures. Functional outcomes were improved at a median of 15 years for feet treated with the Ponseti method compared with feet treated with PMR, with advantages seen in the Ponseti group over several domains. This study provides the most comprehensive evaluation of outcomes close to skeletal maturity in prospective cohorts, reinforcing the Ponseti method as the initial treatment of choice for idiopathic clubfeet.

Abstract
BACKGROUND Understanding the kinematic characteristics of relapse clubfoot compared to successfully treated clubfoot could aid early identification of a relapse and improve treatment planning. The usage of a multi segment foot model is essential in order to grasp the full complexity of the multi-planar and multi-joint deformity of the clubfoot. RESEARCH QUESTION The purpose of this study was to identify differences in foot kinematics, using a multi-segment foot model, during gait between patients with Ponseti treated clubfoot with and without a relapse and age-matched healthy controls. METHODS A cross-sectional study was carried out including 11 patients with relapse clubfoot, 11 patients with clubfoot and 15 controls. Gait analysis was performed using an extended Helen Hayes model combined with the Oxford Foot Model. Statistical analysis included statistical parametric mapping and discrete analysis of kinematic gait parameters of the pelvis, hip, knee, ankle, hindfoot and forefoot in the sagittal, frontal and transversal plane. RESULTS The relapse group showed significantly increased forefoot adduction in relation with the hindfoot and the tibia. Furthermore, this group showed increased forefoot supination in relation with the tibia during stance, whereas during swing increased forefoot supination in relation with the hindfoot was found in patients with relapse clubfoot compared with non-relapse clubfoot. SIGNIFICANCE Forefoot adduction and forefoot supination could be kinematic indicators of relapse clubfoot, which might be useful in early identification of a relapse clubfoot. Subsequently, this could aid the optimization of clinical decision making and treatment planning for children with clubfoot.

Abstract
Clinicians worldwide have embraced Ponseti’s nonoperative approach in the treatment of clubfoot, primarily due to ubiquitous reports of successful outcomes. A crucial component in this measured success, has come from researchers assessing long-term physical function following nonoperative treatment. Gait analysis has been instrumental in objectively evaluating lower extremity kinematics and kinetics while plantar pressures demonstrate the load bearing patterns experienced in the foot. As technology improves, our ability to evaluate function can take place both in the laboratory setting, and in the community. For over 20 years, our institution has been studying the gait patterns of children treated for clubfoot. After adopting the nonoperative approach, we established a prospective research program that has allowed us to study functional outcomes in the very young walker, through growth to adolescents, and finally at skeletal maturity. We have seen over 450 children treated for clubfoot in the Movement Science Lab, for over 1,250 gait assessments over the span of this study. Early results in 105 children (154 feet) treated nonoperatively for clubfoot, showed 56% of children had normal sagittal plane ankle kinematics, however an incidence of 48% of Ponseti feet had increased dorsiflexion in stance phase, leading us to wonder if this was the result of the tenotomy. Intermediate follow up at age 5 years, showed that the incidence of increased dorsiflexion was reduced (24%) and ankle power did not appear to be affected (P>0.05 compared to controls). The research highlighted in this paper presents the application of functional evaluation through growth and the long-term effects of nonoperative treatment on gait and function. This is a review of the functional outcome studies from our experience at Scottish Rite for Children.

Long-term outcomes of the Ponseti method for treatment of clubfoot: a systematic review. INTERNATIONAL ORTHOPAEDICS 2021; 45:2599-2608. [PMID: 34415418 DOI: 10.1007/s00264-021-05189-w] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Accepted: 08/10/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE The Ponseti method has revolutionized the clubfoot treatment and has been adopted globally in the past couple of decades. However, most reported results of the Ponseti method are either short or midterm. Studies reporting long-term outcomes of the Ponseti method are limited. The following systematic review aimed to provide a comprehensive overview of the published articles on long-term outcomes of the Ponseti method. MATERIAL AND METHODS A literature search was performed for articles published in electronic database PubMed (includes Medline) and Cochrane for broad keywords: "Clubfoot"; "Ponseti method/technique"; "long term outcomes/results." Studies selected included full-text articles in English language on children less than one year with primary idiopathic clubfoot treated by the Ponseti method with mean ten year follow-up. Non-idiopathic causes or syndromic clubfoot and case reports/review articles/meta-analyses were excluded. The following parameters were included for analysis: number of patients/clubfeet, male/female, mean age at treatment, mean/range of follow-up, relapses, additional surgery, range of motion, various outcome scores, and radiological variables. RESULTS Fourteen studies with 774 patients/1122 feet were included. The male:female ratio was 2.4:1. Mean follow-up recorded in studies was 14.5 years. Relapses occurred in 47% patients with additional surgery being required in 79% patients with relapses. Of these, 86% of surgery were extra-articular while 14% were intra-articular. Plantigrade foot was achieved in majority patients with mean ankle dorsiflexion of 11 degrees. The outcome scores were in general good in contrast to radiological angles which were mostly outside normal range with talar flattening/navicular wedging/degenerative osteoarthritis changes occurring in 60%, 76%, and 30%, respectively. CONCLUSIONS Long-term follow-up of infants with primary idiopathic clubfeet treated by the Ponseti method revealed relatively high relapse and additional surgery rates. Radiologically, the various angles were inconsistent compared to normal ranges and anatomical deformations/degenerative changes were present in treated feet. Moreover, the relapse rates and requirement of additional surgery increased on long-term follow-up. Despite this, majority feet were plantigrade and demonstrated good clinical results as measured by various outcome tools. There should be emphasis on long-term follow-up of children with clubfeet in view of late relapses and secondary late changes.

Evaluation of Gait Pattern and Lower Extremity Kinematics of Children with Morquio Syndrome (MPS IV). Diagnostics (Basel) 2021; 11:diagnostics11081350. [PMID: 34441285 PMCID: PMC8394369 DOI: 10.3390/diagnostics11081350] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 07/22/2021] [Accepted: 07/24/2021] [Indexed: 11/20/2022] Open
Abstract
Morquio syndrome (mucopolysaccharidosis IV/MPS IV) is a genetic disorder leading to skeletal abnormalities and gait deviations. Research on the gait patterns and lower extremity physical characteristics associated with skeletal dysplasia in children with MPS IV is currently limited. This research aimed to provide baseline gait patterns and lower limb skeletal alignment of children with MPS IV utilizing three-dimensional instrumented gait analysis. This Institutional Review Board-approved retrospective study evaluates the kinematics of the lower extremities of children with MPS IV during gait, comparing them with an age-matched group of typically developing children. Thirty-three children with MPS IV were included (8.6 ± 4.0 years old). Children with MPS IV walk with increased anterior pelvic tilt, knee valgus, knee flexion, external tibial torsion, and reduced walking speed and stride length (p < 0.001). Multiplanar abnormal alignment results in abnormal knee moments (p < 0.001). Limited correlations exist (r = 0.69–0.28) between dynamic three-dimensional measurements of knee varus/valgus and rotational alignment and traditional static two-dimensional measures (physical examination or radiographs) suggesting the possibility of knee instability during gait and the benefits of dynamic assessment.

Talipes Equinovarus Treatment in Infants Treated by the Ponseti Method Compared With Posterior-Only Release: A Mid-Childhood Comparison of Results. J Foot Ankle Surg 2021; 59:919-926. [PMID: 32482579 DOI: 10.1053/j.jfas.2018.12.046] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2018] [Revised: 12/12/2018] [Accepted: 12/24/2018] [Indexed: 02/03/2023]
Abstract
The aim of this study is to evaluate children in middle childhood with clubfoot treated with Ponseti method vs posterior-only release and to compare their results to a control group with 4 modules (physical examination, gait study, radiographic measurements, and questionnaires). From 01/01/2004 until 01/01/2009, 31 children (45 feet) were treated with the posterior-only release protocol and 22 patients (34 feet) were treated with the Ponseti method. In 2016, patients were evaluated and compared with 25 children without neuromuscular disorders. Parents completed 3 outcome questionnaires. Radiographs evaluated residual deformity and osteoarthritis. A physical examination and a 3-dimensional gait analysis were performed to evaluate range of motion, kinematic, and kinetic data. Recurrence rate was similar between treatment groups; however, type of surgery to treat residual deformity was more aggressive in the posterior-only release (91% required major surgery), p = .024. Radiographic examination showed similar residual deformity with greater hindfoot varus in posterior-only release (68%), p = .02. Reduced cadence, increased stance dorsiflexion, calcaneus gait and forced eversion prior to swing were the main characteristics of gait in posterior-only release. Four (11%) feet treated with posterior-only release vs 11 (33%) feet treated with Ponseti method had a normal gait, p = .016. Our study showed that biomechanical function and long-term outcomes of children in middle childhood treated with the Ponseti method more closely compare with healthy individuals than those treated using posterior-only surgical technique.

Agarwal A, Rastogi A, Rastogi P. Relapses in clubfoot treated with Ponseti technique and standard bracing protocol- a systematic analysis. J Clin Orthop Trauma 2021; 18:199-204. [PMID: 34026487 PMCID: PMC8122108 DOI: 10.1016/j.jcot.2021.04.029] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Revised: 04/11/2021] [Accepted: 04/28/2021] [Indexed: 11/29/2022] Open
Abstract
PURPOSE The analysis determined the relapses in clubfoot children treated with Ponseti technique and standard bracing protocol and their correlation with overall follow up duration using pooled data from various series. It also tested the prescribed timelines of 5 and 7 years for slow-down/cessation of relapses in clubfoot children. METHODS A systematic literature search was performed for articles published in "Pubmed (includes Medline indexed journals)" electronic databases using key words: "Clubfoot or CTEV or congenital talipes equinovarus", "Ponseti" for years 1st January 2001 to 15th November 2020. Included were studies that addressed treatment of idiopathic clubfoot using the standard Ponseti technique, followed a well defined brace protocol (maintenance of corrected deformity using a central bar based brace and prescribed duration mentioned), reported a minimum mean follow up of 4 years and having relapse as one of their outcome measure. Studies reporting Ponseti technique for non-idiopathic clubfoot, child's age older than 1 year at the time of primary treatment, clubfoot with previous interventions before Ponseti treatment, where relapse and residual deformities were not identified distinctly in follow up, abstract only publications, letter to the editors, case reports, technique papers and review articles were excluded. The following characteristics of clubfoot patients in the selected articles were included for analysis: Patient numbers/feet treated with Ponseti technique; follow up years (<5; 5-7 and >7 years; overall) and corresponding relapse percentages for patients. RESULTS There were total 2206 patients in the included 24 studies. Average follow up was 6 years. The average relapse rates for clubfoot patients in the pooled data stood at 30%. The overall relapse rates increased with a longer follow up and the curve befitted a linear regression equation with weak positive correlation (Pearson correlation coefficient = 0.08). The relapse rates in follow up categories of <5 years (26.6 ± 15.6%), 5-7 years (30.8 ± 16.3%) and >7 years (28.4 ± 6.2%) were similar statistically (Analysis of variance, ANOVA). CONCLUSIONS Approximately 1 in 3 clubfoot patients suffer relapse post Ponseti technique and standard bracing protocol. A weak positive correlation was observed for relapses when correlated with increasing follow up years. The relapses however tend to slow down after initial growth years. There is a need to educate the care receivers regarding the possibility of late relapses despite proper Ponseti treatment and accordingly to keep them under supervised follow up for longer periods.

Gross motor skill development is similar in children post Ponseti casting for congenital talipes equinovarus compared to typically developing children: a systematic review. J Pediatr Orthop B 2021; 30:264-272.

Abstract
This review aimed to investigate gross motor skill development in children with congenital talipes equinovarus (CTEV) following the Ponseti method of casting and bracing. Summary of evidence revealed through a systematic search of electronic databases completed in May 2019. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was used to report and conduct the study. The McMaster Critical Review Form was used to critically appraise included studies and a descriptive synthesis of the results is reported. Inclusion criteria for studies included participants aged above 4 years, with a diagnosis of CTEV, treated via the Ponseti method and followed up with valid gross motor outcome measures. The comparator was a control group of typically developing children, or reference data. The searches resulted in 619 unique articles. Eight studies (retrospective cohort/case control studies) met inclusion criteria. There were nine different outcome measures used with 29 domains being relevant to this review. Synthesis of the findings found no significant difference between the gross motor skills of children with CTEV treated with Ponseti and typically developing children. The balance domains of three measures were consistently lower for the CTEV group versus controls/normative data. Yet, it is still demonstrated that most gross motor skills are within the typically developing range. It must be considered, however, that there is a spectrum of severity of CTEV and overall gross motor function should be monitored.

Abstract
The objective of this study was to find the effect of hallux valgus (HV) deformity on the inter-segmental motion of the foot using an MFM with a 15-marker set (DuPont Foot Model, DuFM) in comparison with age and sex controlled healthy adults. Fifty-eight female symptomatic HV patients and 50 female asymptomatic older female volunteers were included in this study. According to the radiographic hallux valgus angle (HVA), the study population was divided into severe HV (SHV, HVA ≥ 40°, n = 25), moderate HV (MHV, 20° ≤ HVA < 40°, n = 47), and control (CON, n = 36). MHV group was divided into symptomatic MHV group (S-MHV, n = 33) and asymptomatic MHV group (A-MHV, n = 14) according to the symptoms associated with HV. For temporal parameters, gait speed and stride length were diminished according to the severity of HV deformity. Sagittal range of motion of hallux and hindfoot decreased significantly in SHV group. Loss of push-off during the preswing phase was observed and forefoot adduction motion during terminal stance was decreased in SHV group. In a subgroup analysis of MHV, asymptomatic HV minimally affects gait and inter-segmental motion during gait. HV deformity affects gait parameters and inter-segmental motion of the foot during gait in proportion to the severity of the deformity. However, the effect of MHV itself on foot kinematics might be limited while pain or arthritic change of the joint might cause changes in gait in patients with symptomatic HV.

Abstract
BACKGROUND Idiopathic flexible flatfeet, congenital clubfeet and pes cavovarus are the most common foot deformities in children. Accurate assessment to quantify the severity of these deformities by clinical examination alone can be challenging. Radiographs are a valuable adjunct for accurate diagnosis and effective treatment. However, static radiographs during relaxed standing may not reflect the dynamic changes in the foot skeleton during functional activities such as walking. Therefore, the aim of this study is to predict dynamic foot movements during walking from planar standing radiographs to reveal the significance of the radiographic analysis for the assessment of foot function. METHODS Patients 8-17 years with flexible flatfeet (FFF, n=217) recurrent clubfeet (RCF n=38) and overcorrected clubfeet (OCCF, n=71) of non-neurogenic or syndromic origin and pes cavovarus due to peripheral neuropathy (PNP, n=48) were retrospectively included. Patients underwent gait analysis with the Oxford Foot Model and radiographic examination in anterior-posterior and lateral view during standing. Multilinear predictor analysis of selected gait parameters was performed based on radiographic measures. RESULTS The variance that was explained by radiography was greatest for the transverse plane forefoot abduction with 33% for OCCF, 50% for RCF and 59% for PNP. Flatfeet and foot kinematics in the other planes or between rearfoot and tibia showed little or no relation. CONCLUSIONS The static measures of foot deformities by radiography could explain only a small amount of variance in foot kinematics during walking, in particular for FFF. An explanation may be that the forces during weight bearing bear little resemblance to those during gait in terms of neither magnitude nor direction. These findings suggest that foot function cannot be accurately assessed solely from static radiographic observations of the foot, commonly undertaken in clinical practice.

Abstract
Purpose Although many short-term studies have shown the superiority of Ponseti treatment to surgical treatment, studies with long-term follow-up of patients into adolescence are lacking. The aim of this study was to compare the morphological, functional and radiological results of the two methods into and during adolescent age, when both soft tissue and bony procedures can be performed to correct residual deformities. Patients and Methods We retrospectively evaluated two groups of patients diagnosed with congenital idiopathic clubfoot and treated with either the Ponseti method (34 clubfeet) and surgery in the form of posteromedial release (31 clubfeet). All included clubfeet were clinically fully corrected after initial treatment and final plaster removal. Evaluation was performed with the International Clubfoot Study Group (ICFSG) score. Results The age at follow-up was 12.8±1.6 years in the Ponseti group and 13.5±1.7 years in the surgical group. Excellent or good results were obtained in 26 feet (76%) of the Ponseti group and in 14 feet (45%) in the surgical group. The Ponseti treatment was significantly superior to posteromedial release in terms of the final score (10.58±6.49 versus 17.26±8.83, p<0.001), functional score (p<0.001) and radiological score (p<0.001). Residual deformities were clinically present in both groups but were less frequent and less severe in Ponseti-treated patients. Flat-top talus was found to be present in both groups, but the Ponseti method was more protective than surgical treatment against this outcome (relative risk=0.494, p=0.002). The overall foot and ankle mobility was significantly better in the Ponseti group (p<0.001). Conclusion The Ponseti method was superior to surgery for treatment of clubfoot and achieved better long-term morphological, functional and radiological results. It preserves better mobility of the foot and ankle, and results in less frequent and less severe residual deformities than surgical treatment.

Clubfoot treatment with Ponseti method-parental distress during plaster casting. J Orthop Surg Res 2020; 15:271.

Abstract
Background Clubfoot is one of the most prevalent musculoskeletal congenital defects. Gold standard treatment of idiopathic clubfoot is the conservative Ponseti method, including the reduction of deformity with weekly serial plaster casting and percutaneous Achilles tenotomy. It is well known that parents of children with severe and chronic illnesses are mentally stressed, but in recent studies regarding clubfoot treatment, parents were only asked about their satisfaction with the treatment. Largely unknown is parental distress before and during plaster casting in clubfoot. Therefore, we want to determinate first, how pronounced the parents’ worries are before treatment and if they decrease during the therapy. Second, we hypothesized that parents faced with an extreme deformity (high Pirani score), reveal more distress, than parents whose children have a less pronounced deformity (low Pirani score). Therefore, we wanted to investigate whether the Pirani score correlates with the parents’ mental resilience in relation to the therapy of the child as a global distress parameter. Methods To answer this question, we developed a questionnaire with the following emphases: Physical capacity, mental resilience, motion score, parents score, and child score with point scores 1 (not affected) to 6 (high affected). Subsequently, we interviewed 20 parents whose children were treated with clubfeet and determined the Pirani score of the infants at the beginning (T0) and at the end (TE) of the treatment with plaster casting. Results High values were obtained in child score (Mean (M) = 3.11), motion score (M = 2.63), and mental resilience (M = 2.25). During treatment, mental resilience improved (p = 0.015) significantly. Spearman correlation coefficient between Pirani score (T0) and mental resilience (T0) is 0.21, so the initial hypothesis had to be rejected. Conclusion The issues of the children are in the focus of parental worries concerning clubfoot treatment, especially the assumed future motion and the assumed ability to play with other children. Particular emphasis should be placed on educating parents about the excellent long-term results in the function of the treated feet especially as this topic shows the greatest parental distress.

Abstract
While adoption of the Ponseti method has continued gradually, its use to manage patients with congenital talipes equinovarus (CTEV) has been limited in low- and middle-income countries (LMICs) for a number of reasons including a lack of clinical training on technique and lack of appropriate clinical equipment. There are a frequent number of emerging studies that report on the role of clubfoot training programmes; however, little is known in regard to cumulative benefits. A systematic review was undertaken through Medline, the Cochrane Library and Web of Science for studies analysing clubfoot training programmes. There were no limitations on time, up until the review was commenced on January 2020. The systematic review was registered with PROSPERO as 165657. Ten articles complied with the inclusion criteria and were deemed fit for analysis. Training programmes lasted an average of 2–3 days. There was a reported increase in knowledge of applying the Ponseti method in managing clubfoot by participants (four studies P < 0.05). Skill retention was examined by multiple choice (MCQ) examination style questions before and after the training programme in two studies; both showed an improvement (MCQ answers improved from 59% to 73%). All studies showed an improvement in participants' self-reported understanding of the Ponseti method and confidence in its use in future practice (P < 0.05). There were improved benefits of knowledge and clinical application of the Ponseti method by participants in the programmes in all studies examined. However, there was a significant lack of follow-up and exploration of long-term effects of these programmes. Implementing training programmes based on perceived benefits rather than actual long-term benefits may have a negative impact on healthcare delivery and patient management in LMICs.

Abstract
BACKGROUND Idiopathic talipes equinovarus (ITEV) is a prevalent structural deformity of the foot and ankle in children. The disease-specific instrument (DSI) has commonly been used as an outcomes metric in these patients. The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed to examine the quality of life across various medical conditions. PROMIS has been validated for multiple conditions; however, no studies have evaluated the use of the PROMIS in children with ITEV. METHODS A prospective analysis was performed whereby the 2 questionnaires were mailed out to the parents of 91 patients, aged 5 to 17 years, with ITEV. Construct validity of the PROMIS Parent Proxy Profile short forms version was assessed by comparing its domains of Mobility, Fatigue, Pain Interference, and Pain Intensity to the DSI Function domain and PROMIS domains of Anxiety, Depressive Symptoms, Peer Relationships, and Pain Intensity to DSI Satisfaction domain. RESULTS Thirty-one complete responses (34% response rate) were returned. The patients' current mean age was 8.8 years, 7 were female individuals, and 12 had unilateral ITEV. Bivariate correlation analysis, using Spearman correlation coefficients, demonstrated a moderate positive correlation between the DSI Function domain and the PROMIS Mobility domain (rs=0.52) and a moderate negative correlation between the DSI Function domain and the PROMIS Pain Interference domain (rs=-0.56), as well as the PROMIS Pain Intensity domain (rs=-0.75). A fair negative correlation (rs=-0.38) with PROMIS Fatigue domain was found. Correlations between the DSI Satisfaction domain and the PROMIS domains were fair or had little relationship. CONCLUSIONS These results provide support for the validity of the PROMIS Mobility, Pain Interference, and Pain Intensity domains in this population, however there are no items in PROMIS that can assess overall satisfaction, as with the DSI.

Abstract
BACKGROUND The prevention and treatment of relapsed clubfoot remained challenging tasks. There were controversies as to treatment options and management, such as complete subtalar release, application of an Ilizarov external frame, or repeated Ponseti method; and different options were available in different treatment centers. This study was designed to evaluate the clinical outcome of relapsed clubfeet treated by repeated Ponseti method in comparison with the cases without relapse in term of gait analysis and to clarify the clinical efficacy of repeated Ponseti method in treating the relapsed clubfeet. METHODS Thirty-seven patients (53 feet) were retrospectively identified from our database according to the inclusion and exclusion criteria. Among the 37 patients, 17 cases (25 relapsed clubfeet) were assigned to group I, whereas 20 cases (28 clubfeet without relapse) were assigned to group II. Clinical examination, gait analysis, and kinematic gait deviation criteria from Texas Scottish Rite Hospital for Children were used for evaluation. RESULTS There was statistically significant difference in the parameters of foot length, stride length, and single limb support time (%gait cycle) between the 2 groups (P<0.05). No statistically significant difference was found in the kinematic parameters of total hip, knee, and ankle excursion, peak knee and ankle flexion and extension, and internal foot progression (P>0.05). There was no statistically significant difference in peak hip, knee, and ankle flexion moment, peak knee valgus moment, and peak ankle power (P>0.05). No statistically significant difference was found in equinus and calcaneus gait, increased ankle dorsiflexion, foot drop, and internal foot progression angle (P>0.05). CONCLUSIONS Repeated Ponseti method for relapsed clubfeet can yield good or excellent clinical results. We recommend repeated Ponseti method as the treatment choice for relapsed clubfeet in the early stage. LEVEL OF EVIDENCE Level III-retrospective comparative study.

Abstract
BACKGROUND Little is known regarding gross motor skills (GMS) in children with idiopathic clubfoot (IC). This study describes GMS, specifically foot involvement and asymmetries, and analyses the association between GMS, gait, and foot status in children with IC. METHODS Gross motor tasks and gait were analyzed in children with IC and typically developed (TD) children. GMS were assessed using videotapes and the Clubfoot Assessment Protocol (CAP). The Gait Deviation Index (GDI) and GDI-Kinetic were calculated from gait analyses. Children were divided into bilateral, unilateral clubfoot, or TD groups. To analyze asymmetries, feet within each group were further classified into superior or inferior foot, depending on their CAP scores. Correlations identified associations between CAP and GDI, GDI-Kinetic, passive foot motion, and Dimeglio Classification Scores at birth in the clubfeet. RESULTS In total, 75 children (mean age, 5 years) were enrolled (bilateral n=22, unilateral clubfoot n=25, TD=28). Children with clubfeet demonstrated significantly lower GMS, gait, and foot motion compared with TD children. One leg standing and hopping deviated in 84% and 91%, respectively, in at least one foot in children with clubfoot. Gross motor asymmetries were evident in both children with bilateral and unilateral involvement. In children with unilateral clubfoot, contralateral feet showed few deviations in GMS compared with TD; however, differences existed in gait and foot motion. The association between GMS and gait, foot motion, and initial foot status varied between poor and moderate. CONCLUSIONS Gross motor deficits and asymmetries are present in children with both bilateral and unilateral IC. Development of GMS of the contralateral foot mirrors that of TD children, but modifies to the clubfoot in gait and foot motion. The weak association with gait, foot motion, and initial clubfoot severity indicates that gross motor measurements represent a different outcome entity in clubfoot treatment. We therefore, recommend gross motor task evaluation for children with IC. LEVEL OF EVIDENCE Level II-prognostic studies.

Poor Evertor Muscle Activity Is a Predictor of Recurrence in Idiopathic Clubfoot Treated by the Ponseti Method: A Prospective Longitudinal Study With a 5-Year Follow-up.

Abstract
BACKGROUND After successful primary correction of the deformity in idiopathic clubfoot with the Ponseti method, recurrence has been reported to affect up to 40% of children. So far, it has been difficult to predict which feet are at risk of recurrence, despite numerous studies investigating various potential risk factors. The foot abduction brace (FAB) has been the standard of care in preventing recurrence but, even with excellent compliance, recurrences still occur. Increasingly, evidence points to a congenital neuromuscular imbalance constituting the deforming forces present in clubfoot. Poor evertor muscle activity has been cited specifically as a potential risk factor for recurrence. The aim of this study is to evaluate whether poor evertor muscle activity on clinical examination can predict recurrence in idiopathic clubfoot at 5-year follow-up. METHODS Data were collected prospectively on patients treated at our tertiary physiotherapy-led Ponseti service between 2010 and 2015. Hospital ethical approval was obtained. Sex, age, laterality, Pirani score, number of casts, brace compliance, and evertor activity were recorded. Evertor muscle activity was scored in a semiquantitative repeatable manner: 0, 0.5, or 1 as previously described. Recurrence was defined as deterioration of any of the 4 components of the deformity following a previously complete correction. RESULTS In total, 104 patients (172 feet) were included in the study, 76 patients had good evertor activity, and 28 demonstrated poor evertor activity. The mean follow up was 62 months (range, 41 to 71 mo); 18.3% of the patients (19/104) had recurrence treated with repeat casting; 13.5% (14/104) of the patients required additional surgery following recasting. Recurrence was highly associated with poor evertor activity (P<0.01). CONCLUSIONS Results at 5 years confirm that a semiquantitative evertor muscle activity assessment can predict recurrence and should be added to the routine clinical assessment in order to assist with individualizing patient's treatment strategies.

Abstract
Aims The Ponseti method is the benchmark treatment for the correction of clubfoot. The primary rate of correction is very high, but outcome further down the treatment pathway is less predictable. Several methods of assessing severity at presentation have been reported. Classification later in the course of treatment is more challenging. This systematic review considers the outcome of the Ponseti method in terms of relapse and determines how clubfoot is assessed at presentation, correction, and relapse. Patients and Methods A prospectively registered systematic review was carried out according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies that reported idiopathic clubfoot treated by the Ponseti method between 1 January 2012 and 31 May 2017 were included. The data extracted included demographics, Ponseti methodology, assessment methods, and rates of relapse and surgery. Results A total of 84 studies were included (7335 patients, 10 535 clubfeet). The relapse rate varied between 1.9% and 45%. The rates of relapse and major surgery (1.4% to 53.3%) and minor surgery (0.6% to 48.8%) both increased with follow-up time. There was high variability in the assessment methods used across timepoints; only 57% of the studies defined relapse. Pirani scoring was the method most often used. Conclusion Recurrence and further surgical intervention in idiopathic clubfoot increases with the duration of follow-up. The corrected and the relapsed foot are poorly defined, which contributes to variability in outcome. The results suggest that a consensus for a definition of relapse is needed.

Abstract
Using age and height matched cohorts with unilateral idiopathic clubfeet (n=40 each), we retrospectively reviewed pedobarographic studies to determine the impact of treatment, Ponseti versus comprehensive surgical releases (CSR), on the foot length, width, and contact area. The foot pressures were determined by self-selected walking across a force plate. Ponseti treatment results in more symmetrical foot lengths, widths, and total contact areas with an improvement of 1.3 shoe sizes difference compared with treatment with CSR. This suggests that there is improved growth in the clubfoot in those treated with Ponseti management compared with those treated with CSR.

Abstract
BACKGROUND The purpose of this study was to assess function, at the age of 10 years, of children initially treated nonoperatively for clubfoot with either the Ponseti or French physiotherapy program and to compare outcomes in feet that had undergone only nonoperative treatment with those that required subsequent surgery. METHODS Gait analysis, isokinetic ankle strength, parent-reported outcomes, and daily step activity data were collected when patients who had been treated for idiopathic clubfoot reached the age of 10 years. Patients who had undergone only nonoperative treatment were compared with those who subsequently underwent extra-articular surgery or intra-articular surgery (posterior release or posteromedial release). The clubfoot groups were compared with age-matched controls. RESULTS Of 263 treated clubfeet in 175 patients, 148 had only been treated nonoperatively, 29 underwent extra-articular surgery, and 86 underwent intra-articular surgery (posterior release in 42 and posteromedial release in 44). Significant abnormalities were found in ankle kinetics and isokinetic ankle strength in the feet treated with intra-articular surgery compared with the nonoperatively treated feet (p < 0.017). Compared with controls (n = 40 feet), all groups showed reduced ankle plantar flexion during gait, resulting in a deficit of 9% to 14% for dynamic range of motion, 13% to 20% for ankle moment, and 13% to 23% for power (p < 0.013). Within the intra-articular group, feet that underwent posteromedial release had decreased plantar flexion strength (15%; p = 0.008), dorsiflexion strength (6%; p = 0.048), and parent-reported global function scores (p = 0.032) compared with the posterior release group. The patients with clubfoot took 10% fewer steps (p = 0.015) and had 11% less total ambulatory time (p = 0.001) than the controls. CONCLUSIONS Examination of patients when they had reached the age of 10 years showed better ankle power and isokinetic strength for clubfeet treated without surgery compared with those that underwent intra-articular surgery for residual deformity or recurrence. Compared with controls, both nonoperatively and surgically treated clubfeet had significant limitations in ankle plantar flexion resulting in decreased range of motion, moment, and power. Gastrocnemius-soleus complex strength was decreased after both nonoperative and surgical treatment of clubfeet. Although activity was diminished in the clubfoot population, no differences in function were perceived by the patients' parents. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
BACKGROUND To our knowledge, there are no reports of the Ponseti method initiated after walking age and with >10 years of follow-up. Our goal was to report the clinical findings and patient-reported outcomes for children with a previously untreated idiopathic clubfoot who were seen when they were between 1 and 5 years old, were treated with the Ponseti method, and had a minimum follow-up of 10 years. METHODS A retrospective review of medical records was supplemented by a follow-up evaluation of physical findings (alignment and range of motion) and patient-reported outcomes using the Oxford Ankle Foot Questionnaire for Children (OxAFQ-C). The initial treatment was graded as successful if a plantigrade foot was achieved without the need for an extensive soft-tissue release and/or osseous procedure. RESULTS We located 145 (91%) of 159 patients (220 clubfeet). The average age at treatment was 3 years (range, 1 to 5 years), and the average duration of follow-up was 11 years (range, 10 to 12 years). The initial scores according to the systems of Pirani et al. and Diméglio et al. averaged 5 and 17, respectively, and an average of 8 casts were required. Surgical treatment, most commonly a percutaneous Achilles tendon release (197 feet; 90%), was required in 96% of the feet. A plantigrade foot was achieved in 95% of the feet. Complete relapse was rare (3%), although residual deformities were common. Patient-reported outcomes were favorable. CONCLUSIONS A plantigrade foot was achieved in 95% of the feet initially and was maintained in most of the patients, although residual deformities were common. Patient-reported outcomes were satisfactory, and longer-term follow-up with age-appropriate outcome measures will be required to evaluate function in adulthood.

Abstract
PURPOSE Although non-idiopathic clubfeet were long thought to be resistant to non-surgical treatment methods, more studies documenting results on treatment of these feet with the Ponseti method are being published. The goal of this systematic review is to summarize current evidence on treatment of non-idiopathic clubfeet using the Ponseti method. METHODS PubMed and Limo were searched, reference lists of eligible studies were screened and studies that met the inclusion criteria were included. Data on average number of casts, Achilles tendon tenotomy (ATT), initial correction, recurrence, successful treatment at final follow-up and complications were pooled. The Methodological Index for Non-Randomized Studies was used to assess the methodological quality of the selected studies. RESULTS In all, 11 studies were included, yielding a total of 374 non-idiopathic and 801 idiopathic clubfeet. Non-idiopathic clubfeet required more casts (7.2 versus 5.4) and had a higher rate of ATT (89.4% versus 75.7%). Furthermore, these feet had a higher recurrence rate (43.3% versus 11.5%) and a lower rate of successful treatment at final follow-up (69.3% versus 95.0%). Complications were found in 20.3% of the non--idiopathic cohort. When comparing results between clubfeet associated with myelomeningocele and arthrogryposis, the first group presented with a lower number of casts (5.4 -versus 7.2) and a higher rate of successful treatment at final follow-up (81.8% versus 58.2%). CONCLUSION The Ponseti method is a valuable and non-invasive option in the primary treatment of non-idiopathic clubfeet in young children. Studies with longer follow-up are necessary to evaluate its long-term effect.

Abstract
Background The use of three-dimensional multi-segment foot models (3D MFMs) is increasing since they have superior ability to illustrate the effect of foot and ankle pathologies on intersegmental motion of the foot compared to single-segment foot model gait analysis. However, validation of the repeatability of the 3D MFMs is important for their clinical use. Although many MFMs have been validated in normal adults, research on MFM repeatability in children is lacking. The purpose of this study is to validate the intrasession, intersession, and interrater repeatability of an MFM with a 15-marker set (DuPont foot model) in healthy children. Methods The study included 20 feet of 20 healthy children (10 boys and 10 girls). We divided the participants into two groups of 10 each. One group was tested by the same operator in each test (intersession analysis), while the other group was tested by a different operator in each test (interrater analysis). The multiple correlation coefficient (CMC) and intraclass correlation coefficient (ICC) were calculated to assess repeatability. The difference between the two sessions of each group was assessed at each time point of gait cycle. Results The intrasession CMC and ICC values of all parameters showed excellent or very good repeatability. The intersession CMC of many parameters showed good or better repeatability. Interrater CMC and ICC values were generally lower for all parameters than intrasession and intersession. The mean gaps of all parameters were generally similar to those of the previous study. Conclusions We demonstrated that 3D MFM using a 15-marker set had high intrasession, intersession, and interrater repeatability in the assessment of foot motion in healthy children but recommend some caution in interpreting the hindfoot parameters.

Abstract
BACKGROUND Currently, the Ponseti method is the gold standard for treatment of clubfeet. For long-term functional evaluation of this method, gait analysis can be performed. Previous studies have assessed gait differences between Ponseti treated clubfeet and healthy controls. RESEARCH QUESTION/PURPOSE The aims of this systematic review were to compare the gait kinetics of Ponseti treated clubfeet with healthy controls and to compare the gait kinetics between clubfoot patients treated with the Ponseti method or surgically. METHODS A systematic search was performed in Embase, Medline Ovid, Web of Science, Scopus, Cochrane, Cinahl ebsco, and Google scholar, for studies reporting on gait kinetics in children with clubfeet treated with the Ponseti method. Studies were excluded if they only used EMG or pedobarography. Data were extracted and a risk of bias was assessed. Meta-analyses and qualitative analyses were performed. RESULTS Nine studies were included, of which five were included in the meta-analyses. The meta-analyses showed that ankle plantarflexor moment (95% CI -0.25 to -0.19) and ankle power (95% CI -0.89 to -0.60, were significantly lower in the Ponseti treated clubfeet compared to the healthy controls. No significant difference was found in ankle dorsiflexor and plantarflexor moment, and ankle power between clubfeet treated with surgery compared to the Ponseti method. SIGNIFICANCE Differences in gait kinetics are present when comparing Ponseti treated clubfeet with healthy controls. However, there is no significant difference between surgically and Ponseti treated clubfeet. These results give more insight in the possibilities of improving the gait pattern of patients treated for clubfeet.

Abstract
Introduction Clubfoot affects around 174 000 children born annually, with approximately 90% of these in low-income and middle-income countries (LMIC). Untreated clubfoot causes life-long impairment, affecting individuals’ ability to walk and participate in society. The minimally invasive Ponseti treatment is highly effective and has grown in acceptance globally. The objective of this cross-sectional study is to quantify the numbers of countries providing services for clubfoot and children accessing these. Method In 2015–2016, expected cases of clubfoot were calculated for all countries, using an incidence rate of 1.24/1000 births. Informants were sought from all LMIC, and participants completed a standardised survey about services for clubfoot in their countries in 2015. Data collected were analysed using simple numerical analysis, country coverage levels, trends over time and by income group. Qualitative data were analysed thematically. Results Responses were received from 55 countries, in which 79% of all expected cases of clubfoot were born. More than 24 000 children with clubfoot were enrolled for Ponseti treatment in 2015. Coverage was less than 25% in the majority of countries. There were higher levels of response and coverage within the lowest income country group. 31 countries reported a national programme for clubfoot, with the majority provided through public–private partnerships. Conclusion This is the first study to describe global provision of, and access to, treatment services for children with clubfoot. The numbers of children accessing Ponseti treatment for clubfoot in LMIC has risen steadily since 2005. However, coverage remains low, and we estimate that less than 15% of children born with clubfoot in LMIC start treatment. More action to promote the rollout of national clubfoot programmes, build capacity for treatment and enable access and adherence to treatment in order to radically increase coverage and effectiveness is essential and urgent in order to prevent permanent disability caused by clubfoot.

Abstract
PURPOSE The aim of the study was to examine motor abilities in children treated for idiopathic clubfoot with either the traditional extensive surgery method or the Ponseti method, and compare their motor skills with a control group without clubfoot. METHODS A total of 89 children treated according to the traditional method (mean age 9.0 years, 7 to 10) and 93 treated ad modum Ponseti (mean age 8.8 years, 7 to 10) were recruited from a multicentre clinical study in Norway. A total of 45 age-matched children without clubfoot were recruited from a nearby school. They were all assessed with the Movement Assessment Battery for Children - Second Edition (MABC-2), which evaluates motor performance. We applied Analysis of Covariance for comparison of the two treatment methods and adjusted for gender, laterality, comorbidity, achillotomy or more extended surgery, physiotherapy and the age when the child walked independently. RESULTS We found no significant difference in any of the various components or the total score of the MABC-2 between patients treated with the two different methods. In all, 76% of the children treated according to the traditional method and ad modum Ponseti, and 96% in the control group, respectively, were classified as having normal motor abilities. CONCLUSION About three-quarters of children aged nine years and treated for idiopathic clubfoot had normal motor abilities. We found similar results in patients treated with the traditional method and the Ponseti method. LEVEL OF EVIDENCE II.

Abstract
Recent trends have led to an interest in Ponseti treatment for correcting neglected congenital clubfoot. Although good clinical and functional outcomes have been reported, the plantar pressure distribution after the treatment of neglected clubfoot has not been explored yet. The present study aimed to investigate whether plantar pressures normalized following Ponseti treatment in patients with neglected congenital clubfoot. Pedobarographic, clinical, and functional examinations were performed in 22 children (aged, 91.0 ± 40.3 months) with unilateral neglected congenital clubfeet, treated using Ponseti method at 27.8 ± 12.1 months of age. Plantar pressure parameters were recorded using a Footscan pressure plate. The contact time, contact area, peak pressure, and pressure-time integral were determined. The data of the affected feet were compared with those of the unaffected feet and healthy controls. Although clinical and functional examinations showed satisfactory results according to the Dimeglio and Pirani scores, considerable differences in plantar pressure parameters were identified among the affected feet, unaffected feet, and healthy controls. Internal foot progression angle and a load transfer from the medial forefoot and hindfoot to the lateral forefoot and midfoot were observed in the affected feet. Future studies should attempt to investigate the factors accounting for plantar pressure deviations and the possible effect of these deviations on the lower limb musculoskeletal development of children.

Ponseti method is superior to surgical treatment in clubfoot - Long-term, randomized, prospective trial. Gait Posture 2017; 58:346-351. [PMID: 28866453 DOI: 10.1016/j.gaitpost.2017.08.010] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2016] [Revised: 07/27/2017] [Accepted: 08/07/2017] [Indexed: 02/02/2023]
Abstract
Treatment of idiopathic clubfoot has shifted from extensive surgical release to conservative Ponseti method; however, randomized prospective trials to compare both methods are lacking. The goal of this study was to compare the long-term results of Ponseti method with those of surgery in terms of morphology, function, X-rays, overall health and gait. In 2001, a single center, prospective, randomized, and controlled trial with a parallel design was started. Twenty-four feet of 15 patients were randomly assigned to two groups: 12 feet each to a Ponseti and surgical group. Mean follow-up was 10 years. International Clubfoot Study Group score (ICFSG), the Pediatric Outcomes Data Collection Instrument (PODCI) and the Functional Rating System (FRS) were used to compare morphology, functional, radiological and subjective outcomes, and the Oxford Foot Model (OFM) was used to evaluate foot kinematics. No significant difference was seen between groups in the initial Pirani scores (p=0.618). Ponseti group had more favorable long-term outcomes according to the FRS (p=0.005), higher ICFSG, scores for morphology (p=0.021), function (p=0.005) and X-rays (p=0.02), and better parent reported functional status according to the PODCI (p=0.018). Surgically treated clubfeet were stiffer - ankle dynamic range of motion (p=0.015) and the maximal hindfoot dorsiflexion during gait were limited as measured by OFM (p=0.039). This was compensated by an increase in motion between the hindfoot and forefoot. Furthermore, these children had more difficulty playing sports and experienced more pain, which might have led to inferior results in the happiness domain of the PODCI. These results suggest that the Ponseti method provides superior long-term outcomes for idiopathic clubfoot deformity.

Abstract
BACKGROUND Although accumulative evidence exists that support the applicability of multi-segmental foot models (MFMs) in evaluating foot motion in various pathologic conditions, little is known of the effect of aging on inter-segmental foot motion. The objective of this study was to evaluate differences in inter-segmental motion of the foot between older and younger adult healthy females during gait using a MFM with 15-marker set. METHODS One hundred symptom-free females, who had no radiographic evidence of osteoarthritis, were evaluated using MFM with 15-marker set. They were divided into young (n = 50, 20-35 years old) and old (n = 50, 60-69 years old) groups. Coefficients of multiple correlations were evaluated to assess the similarity of kinematic curve. Inter-segmental angles (hindfoot, forefoot, and hallux) were calculated at each gait phase. To evaluate the effect of gait speed on intersegmental foot motion, subgroup analysis was performed according to the similar speed of walking. RESULTS Kinematic curves showed good or excellent similarity in most parameters. Range of motion in the sagittal (p < 0.001) and transverse (p = 0.001) plane of the hallux, and sagittal (p = 0.023) plane of the forefoot was lower in older females. The dorsiflexion (p = 0.001) of the hallux at terminal stance and pre-swing phases was significantly lower in older females. When we compared young and older females with similar speed, these differences remained. CONCLUSIONS Although the overall kinematic pattern was similar between young and older females, reduced range of inter-segmental motion was observed in the older group. Our results suggest that age-related changes need to be considered in studies evaluating inter-segmental motion of the foot.

Abstract
INTRODUCTION Posterior capsulotomy can correct residual clubfoot deformity, but has been associated with ankle stiffness. The purpose of this study was to evaluate clinical ankle range of motion (ROM) following posterior capsulotomy immediately postsurgery and during long-term follow-up. METHODS A retrospective clinical and radiographic review of 257 patients (398 feet) was performed to evaluate all patients who required a posterior capsulotomy as part of their clubfoot management. Twenty feet (16 patients) were identified with a mean age of 73.3±37.7 months and mean Pirani score of 5.2±0.8 points. Following capsulotomy, a long-leg cast was placed and maintained for a mean of 26 days (range, 21 to 35 d). At cast removal, parents were trained and instructed to immediately begin home physiotherapy. The capsulotomy cohort was age and sex matched to a cohort treated exclusively with the Ponseti method for comparison. Children in the comparison cohort had a mean Pirani score of 5.7±0.8 points. RESULTS The mean dorsiflexion in the capsulotomy cohort significantly increased comparing the preoperative to the immediate postoperative ROM (from -6.5 to +9.7 degrees). No significant reduction in this gain was observed at latest follow-up (to +8.3 degrees). No significant difference in the plantar-flexion angle was found. Radiographically, a significant improvement in the lateral anterior tibial-calcaneal angle angles was found (P<0.05). CONCLUSIONS If utilizing our protocol for early mobilization, limited use of capsulotomy to treat relapsed clubfoot does not necessarily reduce ankle ROM. Our protocol of placing the feet in casts for a shorter duration of time and providing early physiotherapy helps maintain ankle ROM after a posterior capsulotomy. LEVEL OF EVIDENCE Level III-therapeutic study.

Abstract
- A delegation of 6 pediatric orthopedic surgeons from the Dutch Orthopedic Association (NOV) and 2 members of the board of the Dutch Parents' Association for children with clubfoot created the guideline "The diagnosis and treatment of primary idiopathic clubfeet" between April 2011 and February 2014. The development of the guideline was supported by a professional methodologist from the Dutch Knowledge Institute of Medical Specialists. This evidence-based guideline process was new and unique, in the sense that the process was initiated by a parents' association. This is the first official guideline in pediatric orthopedics in the Netherlands, and to our knowledge it is also the first evidence-based guideline on clubfoot worldwide. The guideline was developed in accordance with the criteria of the international AGREE instrument (AGREE II: Appraisal of Guidelines for Research and Evaluation II). The scientific literature was searched and systematically analyzed. In the second phase, conclusions and recommendations in the literature were formulated according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method. Recommendations were developed considering the balance of benefits and harms, the type and quality of evidence, the values and preferences of the people involved, and the costs. The guideline is a solid foundation for standardization of clubfoot treatment in the Netherlands, with a clear recommendation of the Ponseti method as the optimal method of primary clubfoot treatment. We believe that the format used in the current guideline sets a unique example for guideline development in pediatric orthopedics that may be used worldwide. Our format ensured optimal collaboration between medical specialists and parents, and resulted in an important change in clubfoot care in the Netherlands, to the benefit of medical professionals as well as parents and patients. In this way, it is possible to improve professional collaboration between medical specialists and parents, resulting in an important change in clubfoot care in the Netherlands that will benefit medical professionals, parents, and patients. The guideline was published online, and is freely available from the Dutch Guideline Database ( www.richtlijnendatabase.nl ).

Acta Orthop 2016; 87:522-8. [PMID: 27331243 PMCID: PMC5016913 DOI: 10.1080/17453674.2016.1202013] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2016] [Accepted: 04/29/2016] [Indexed: 02/08/2023] Open
Abstract
Background and purpose - Idiopathic clubfoot can be bilateral or unilateral; however, most studies of gait have assessed clubfoot cases as one uniform group. The contralateral foot in children with unilateral clubfoot has shown deviations in pedobarographic measurements, but it is seldom included in studies of gait. We evaluated gait in children with idiopathic clubfoot, concentrating on foot involvement. Patients and methods - Three-dimensional gait analyses of 59 children, mean age 5.4 years, with bilateral (n = 30) or unilateral (n = 29) idiopathic clubfoot were stratified into groups of bilateral, unilateral, or contralateral feet. Age-matched controls (n = 28) were evaluated for comparison. Gait assessment included: (1) discrete kinematic and kinetic parameters, and (2) gait deviation index for kinematics (GDI) and kinetics (GDI-k). Results - No differences in gait were found between bilateral and unilateral idiopathic clubfoot, but both groups deviated when compared to controls. Compared to control feet, contralateral feet showed no deviations in discrete gait parameters, but discrepancies were evident in relation to unilateral clubfoot, causing gait asymmetries in children with unilateral involvement. However, all groups deviated significantly from control feet according to GDI and GDI-k. Interpretation - Bilateral and unilateral idiopathic clubfoot cases show the same persistent deviations in gait, mainly regarding reduced plantarflexion. Nevertheless, knowledge of foot involvement is important as children with unilateral clubfoot show gait asymmetries, which might give an impression of poorer deviations. The results of GDI/GDI-k indicate global gait adaptations of the contralateral foot, so the foot should preferably not be used as a reference for gait.

Abstract
PURPOSE Despite few studies comparing Ponseti treatment and traditional treatment of clubfoot (talipes equinovarus), the Ponseti method is now accepted as standard treatment for this deformity. The Ponseti method was introduced in Norway in 2003 and the purpose of this multicenter-study was to compare the results of Ponseti treatment with the results of the previous treatment for clubfoot in Norway. METHODS 90 children (134 clubfeet) treated with previous treatment (pre-Ponseti group), were compared to 115 Ponseti treated children (160 clubfeet) (Ponseti group). The previous treatment consisted of casting and surgery if needed. At 8-11 years of age, all children were examined by the same orthopaedic surgeon, the parents answered a questionnaire, all feet were X-rayed and information about surgical procedures was obtained from the patient records. RESULTS The number of surgeries was higher in the pre-Ponseti group, and the number of extensive surgeries was 119 in the pre-Ponseti group compared to 19 in the Ponseti group. The range of motion in the ankle joint was better in the Ponseti group. Children in this group had better function, higher satisfaction and less pain according to patient and parent reported outcome measures. The incidence of moderate or severe talar flattening was higher in the pre-Ponseti group. CONCLUSION Ponseti treatment seems to be superior to the previous treatment in Norway, with regards to number and severity of operations, flexibility of the foot and ankle, parent/patient reported outcome and the presence of talar flattening on X-ray.

Abstract
Relapse after successful initial correction of idiopathic clubfoot with the Ponseti method is often related to poor compliance with the foot abduction orthosis (FAO). The aim of this study was to evaluate treatment with custom-made dynamic orthoses. Twenty children with idiopathic clubfoot (30feet) who had been treated with dynamic orthoses after the correction phase according to the Ponseti casting technique were evaluated. Relapse rates during orthotic treatment were registered. A Vicon gait analysis system was used to measure gait parameters at the age of seven years. The overall gait quality was estimated with the Gait Deviation Index (GDI). Data were analyzed with a nested mixed model and compared with a control group of 16 healthy children. No relapse occurred during the orthotic treatment. High compliance with the orthoses was observed based on parents' self report and physiotherapist observations. Gait analysis showed decreased ankle power and moment, increased internal foot progression, decreased dorsiflexion during stance, and increased plantar flexion at initial contact compared with the control group. Hip and shank rotations were normal. No calcaneus or equinus gait was observed. The mean GDI was 89.7 (range 71.6-104). The gait analysis outcomes and frequency of relapse were comparable to those of previous studies. Internal foot progression originated primarily from the foot level and was not, as frequently found after FAO treatment, compensated by external rotation at knee or hip level. In children exhibiting poor compliance with an FAO, this dynamic model is considered an effective alternative.

Abstract
BACKGROUND Initial correction following nonoperative (NonOp) treatment for idiopathic clubfoot has been reported in 95% of feet by age 2; however, by age 4, approximately one third of feet undergo surgery due to relapse. The purpose of this study was to assess the longitudinal effect of growth and surgical (Sx) intervention on gait following NonOp and Sx treatment for clubfoot. METHODS Children with idiopathic clubfoot were seen for gait analysis at 2 and 5 years of age. Kinematic data were collected at both visits, and kinetic data were collected at age 5 years. Group comparisons were made between feet treated with the Ponseti casting technique (Ponseti) and the French physical therapy method (PT) and between feet treated nonoperatively and surgically. Comparisons were made between feet treated with a limited release or tendon transfer (fair) and those treated with a full posteromedial release (poor). The α was set to 0.05 for all statistical analyses. RESULTS Gait data from 181 children with 276 idiopathic clubfeet were collected at both age 2 and 5 years. Each foot was initially treated with either the Ponseti (n=132) or PT (n=144) method but by the 5-year visit, 30 Ponseti and 61 PT feet required surgery. Gait outcomes showed limitations primarily in the Sx clubfeet. Normal ankle motion was only present in 17% of Ponseti and 21% of PT feet by age 5 following Sx management. Sx PT feet showed persistent intoeing at age 2 and 5. Within the Sx group, feet initially treated with PT had a clinically significant reduction in ankle power compared with those treated initially by the Ponseti method. Feet treated with posteromedial releases had significantly less ankle power than those treated with limited surgery or that remained NonOp at 5 years. CONCLUSIONS This longitudinal study shows subtle changes between 2 and 5 years, and continues to support a NonOp approach in the treatment of clubfoot. LEVEL OF EVIDENCE Level II-therapeutic.

Abstract
BACKGROUND Assessment of children treated nonoperatively for idiopathic clubfoot, has primarily focused on the kinematic and kinetic results measured with gait analysis (GA). Excellent results in ankle motion and push-off power during gait have been reported at age 5; however, the assessment of gross motor function, has not been evaluated. The purpose of this study was to look at the relationship between gait measures, Peabody Developmental Motor Scales and parent-perception of their child's outcome [measured with the Pediatric Outcomes Data Collection Instrument (PODCI)]. METHODS A total of 81 children with idiopathic clubfoot were seen for both GA and Peabody testing. Children who initially underwent the Ponseti technique (n=29), the French Physical Therapy method (PT) (n=23), and a group of children initially treated nonoperatively, but who required surgical intervention before GA at 5 years of age (n=29) were enrolled. Pearson's correlation coefficient was used to establish significant relationships between gait variables, Peabody, and PODCI scores. RESULTS Gait data showed that the Ponseti treated feet had significantly greater ankle power than feet treated surgically (P=0.0075). The Peabody results showed that the PT feet had higher stationary (P=0.0332) and overall gross motor quotient percent (GMQ%) scores (P=0.0092) than the surgical feet. No differences were found in PODCI scores. Ankle power was weakly correlated to the GMQ% (r=0.29; P=0.0102); however, the GMQ% showed a strong correlation to the parent report of Global Functioning Scale on the PODCI (r=0.48; P=0.0005). CONCLUSIONS Minimal gait disturbances do not interfere with function or parental assessment of abilities and satisfaction at 5-year follow-up in children with idiopathic clubfeet. Nonoperative correction of clubfeet should be the goal when possible, as the Peabody scores show better function as early as 5 years of age when surgery is not required.

Abstract
BACKGROUND Ponseti serial casting is the most commonly used method in North America to treat children with clubfeet. Despite initial correction, recurrence is common. tibialis anterior tendon transfer (TATT) is commonly used to treat recurrent clubfeet. Recurrence can occur after TATT, and patients at risk of recurrence may benefit from closer monitoring. We studied the rate of second recurrence (recurrence after TATT) and studied the predictive factors for this recurrence. METHODS Retrospective chart review of patients who have undergone TATT for recurrent clubfeet between 2002 and 2010 at our institution was performed. Recurrence was defined as recurrence of any elements of the clubfoot deformity that requires operative or nonoperative treatment. Effect of age at the time of TATT, initial severity of the deformity, and family history of clubfoot on rate of recurrence was studied. RESULTS Sixty patients with 85 clubfeet were included in the study. Sixteen feet in 12 patients (20%) developed recurrence after TATT. Eight feet were treated nonoperatively and the rest (8 feet) required surgical procedure. Young age at time of TATT and brace noncompliance significantly increased the rate of second recurrence. Effect of severity of initial deformity and family history did not reach statistical significance. CONCLUSIONS Second recurrence can happen in around one fifth of patients with clubfeet after TATT. Patients with young age at TATT and patients with brace noncompliance are at an increased risk of recurrence and should be monitored closely. LEVEL OF EVIDENCE Level II-prognostic.

Abstract
BACKGROUND The Ponseti method is the preferred treatment for idiopathic clubfoot. Although popularised by orthopaedic surgeons it has expanded to physiotherapists and other health practitioners. This study reviews the results of a physiotherapist-led Ponseti service for idiopathic and non-idiopathic clubfeet and compares these results with those reported by other groups. METHOD A prospective cohort of clubfeet (2005-2012) with a minimum 2-year follow-up after correction was reviewed. Physiotherapists treated 91 children-41 patients (69 feet) had non-idiopathic deformities and 50 children (77 feet) were idiopathic. Objective outcomes were evaluated and compared to results from other groups managing similar patient cohorts. RESULTS The mean follow-up was 4.6 years (range 2-8.3 years) for both groups. The non-idiopathic group required a median of 7 casts to correct the clubfoot deformity with an 83 % tenotomy rate compared to a median of 5 casts for the idiopathic group with a 63 % tenotomy rate. Initial correction was achieved in 96 % of non-idiopathic feet and in 100 % of idiopathic feet. Recurrence requiring additional treatment was higher in the non-idiopathic group with 40 % of patients (36 % of feet) sustaining a relapse as opposed to 8 % (6 % feet) in the idiopathic group. Surgery was required in 26 % of relapsed non-idiopathic feet and 6 % of idiopathic. CONCLUSIONS Although Ponseti treatment was not as successful in non-idiopathic feet as in idiopathic feet, deformity correction was achieved and maintained in the mid-term for the majority of feet. These results compare favourably to other specialist orthopaedic-based services for Ponseti management of non-idiopathic clubfeet. LEVEL OF EVIDENCE Prognostic Level III.

Ponseti casting for severe club foot deformity: are clinical outcomes promising? Adv Orthop 2015; 2015:821690. [PMID: 25755894 PMCID: PMC4338373 DOI: 10.1155/2015/821690] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2014] [Revised: 01/10/2015] [Accepted: 01/15/2015] [Indexed: 11/17/2022] Open
Abstract
Between 2007 and 2010, a prospective study was done on 85 patients with severe idiopathic nonsyndromic clubfeet, in our center. Demographic features, severity of the deformity before and after serial casting according to Diméglio classification, and complications were assessed. The mean age of the patients was 8 days and 69% were male. The mean follow-up period was 26 months. The average number of castings used to correct the deformity was 5.7 times (range: 4 to 8). Tenotomy was performed in 76 (89.4%) of the feet. In all patients, plantigrade foot was achieved. Tenotomy occurred more in patients with higher Diméglio scores. Although patients who underwent Achilles tenotomy began to walk later than those who did not (13 ± 7.2 versus 9.2 ± 18), it was not significant (P = 0.06). Relapse rate, at the end of follow-up, was 27.1%. Diméglio score before casting was 16 ± 3.4 and at the end of follow-up it was 1.6 ± 6.2. The patients with bilateral clubfeet had inferior final outcome compared to those with unilateral clubfoot. Eighty percent of parents' were completely satisfied with their child's gait and foot appearance (94.1%). Ponseti method of manipulation and casting is a valuable technique in severe club foot as well as in common types.

Abstract
Although the main aim of clubfoot correction is to create a foot without limitations in daily activities and sport, studies on the walking capacity of children with corrected clubfeet are rare. In this cross-sectional study, the outcome of the six-minute walking test in 44 children with clubfeet (16 unilateral and 28 bilateral, mean age 8.57±2.45 years) was compared with the reference values of Geiger, clinical status measured with the Clubfoot Assessment Protocol (CAP), and regression analysis used to calculate which CAP subgroup predicts walking capacity. The mean walking capacity was decreased to 79% (P<0.001) and was not influenced by unilaterality or bilaterality (P=0.437). The subgroup CAP morphology was a significant predictor (R=0.103; P=0.034). Knowing that walking capacity is only slightly decreased can help adjust expectations and set goals for training.

Abstract
BACKGROUND The aim of the study was to evaluate how clubfeet treated with the Ponseti method compare with control feet in gait analysis and whether additional information can be provided by the Oxford foot model. METHODS All patients with a minimum age of three years in our prospective database of clubfeet treated with the Ponseti method were considered for inclusion. Exclusion criteria were an associated syndrome or neurological disease, positional (slight) clubfoot, and presentation at an age of more than three months. Of the 125 patients with 199 clubfeet who satisfied the criteria, thirty-six (29%) agreed to participate in the study. Four of these were excluded because of insufficient gait analysis data, leaving thirty-two patients with fifty clubfeet for evaluation. Clinical examination and three-dimensional gait analysis including the Oxford foot model were performed, and a disease-specific questionnaire was administered. Kinetic and kinematic results were compared with those of an age-matched control group (n = 15). RESULTS The mean score on the disease-specific questionnaire was 83.5. Gait analysis showed significantly decreased range of motion, plantar flexion, and power of the ankle compared with controls. The mean external foot progression angle of 5.7° in the Ponseti group was slightly less than that in the controls. Slight intoeing occurred in 24%, and 12% did not achieve a neutral position during swing phase. Slight compensation was observed, including external rotation of the hip in 28%. The Oxford foot model revealed differences in foot motion between the groups. CONCLUSIONS Clubfoot treatment with the Ponseti method yielded good clinical results with high functional scores. Three-dimensional gait analysis demonstrated distinctive but slight deviations. Intoeing was less frequent and less severe compared with groups in the literature. We recommend the use of three-dimensional gait analysis, including a foot model, as an objective tool for evaluation of the results of clubfoot treatment. LEVEL OF EVIDENCE Therapeutic Level II.

Abstract
PURPOSE Our objective is to report longitudinal outcomes of selective surgical soft tissue release for idiopathic clubfoot (ICF). METHODS Thirty-six ICF patients who had surgery at the average age of 11 (range nine to 17) months and 12 age-matched normal feet were evaluated yearly until subjects had the average age of 11 (range seven to 19) years using eight radiographic parameters. The Ponseti and Dimeglio scores were rated. Serial ankle and subtalar motions and talocalcaneal (TC) index changes over time were analyzed using mixed effects random-intercept longitudinal models. RESULTS At the last follow-up, ankle and subtalar motions were more restricted in the ICF but no significant changes in motion were observed over follow-up, except for small but significant decreases in the TC index in both ICF and control feet. The average measurement in ICF group versus control revealed significantly lower angles in the five assessed parameters. The mean Ponseti score was 88 (range 40-97) and ICF showed an improvement of the Dimeglio score. A positive correlation between the Ponseti score and the subtalar motion was noted, whereas talar flattening had a negative influence on the ankle motion. CONCLUSIONS Soft tissue release surgery limited to only pathologies encountered during the procedure maintains motions of ankle and subtalar joints in ICF.
