Non-surgical management of posterior tibial tendon dysfunction- a UK survey.

BACKGROUND: Posterior Tibial Tendon Dysfunction (PTTD) is commonly seen within musculoskeletal care. The condition's prevalence and management is poorly understood. This study aims to demonstrate current practice by multi-professional clinicians across the United Kingdom within the National Health Service. METHODS: A national (UK) cross-sectional online survey was conducted among multi-professionals who treat PTTD within their NHS practice. The survey covered assessment, management and evaluation. This was shared via social media and professional groups. RESULTS: Two hundred thirteen surveys were completed, with 153 matching the eligibility criteria. The main respondents were Physiotherapists (48%) and Podiatrists (38%). Ultrasound scanning was used most frequently when considering initial imaging (67%). Many different treatment modalities were used, but a core set of education/advice, foot orthoses, and foot specific as well as general exercise were most commonly chosen. Outcome measures routinely used were pain scale (96/269) and single leg heel raise (84/269), but patient reported outcome measures were not routinely used. The most frequent reason to escalate care was failure to manage symptoms with conservative management (106/123; 86.2%), followed by fixed deformity (10/123; 8.2%). CONCLUSIONS: This survey provides evidence on current non-surgical management for PTTD from UK NHS practice. It provides a valuable marker for clinicians to use to compare their own practice and can be used in further research as a comparator.

Characteristics and Future Direction of Tibialis Posterior Tendinopathy Research: A Scoping Review.

Background and Objectives: Tibialis posterior tendon pathologies have been traditionally categorized into different stages of posterior tibial tendon dysfunction (PTTD), or adult acquired flatfoot deformity (AAFD), and more recently to progressive collapsing foot deformity (PCFD). The purpose of this scoping review is to synthesize and characterize literature on early stages of PTTD (previously known as Stage I and II), which we will describe as tibialis posterior tendinopathy (TPT). We aim to identify what is known about TPT, identify gaps in knowledge on the topics of TPT, and propose future research direction. Materials and Methods: We included 44 studies and categorized them into epidemiology, diagnosis, evaluation, biomechanics outcome measure, imaging, and nonsurgical treatment. Results: A majority of studies (86.4%, 38 of 44 studies) recruited patients with mean or median ages greater than 40. For studies that reported body mass index (BMI) of the patients, 81.5% had mean or median BMI meeting criteria for being overweight. All but two papers described study populations as predominantly or entirely female gender. Biomechanical studies characterized findings associated with TPT to include increased forefoot abduction and rearfoot eversion during gait cycle, weak hip and ankle performance, and poor balance. Research on non-surgical treatment focused on orthotics with evidence mostly limited to observational studies. The optimal exercise regimen for the management of TPT remains unclear due to the limited number of high-quality studies. Conclusions: More epidemiological studies from diverse patient populations are necessary to better understand prevalence, incidence, and risk factors for TPT. The lack of high-quality studies investigating nonsurgical treatment options is concerning because, regardless of coexisting foot deformity, the initial treatment for TPT is typically conservative. Additional studies comparing various exercise programs may help identify optimal exercise therapy, and investigation into further nonsurgical treatments is needed to optimize the management for TPT.

Comparison of the effects of low level laser and insoles on pain, functioning, and muscle strength in subjects with stage 2 posterior tibial tendon dysfunction: A randomized study.

BACKGROUND: Low level laser therapy (LLLT) is known to be effective in tendinopathies. No study yet investigated the effect of LLLT on posterior tibial tendon dysfunction (PTTD) in comparison to orthotic treatment. OBJECTIVE: The aim was to compare the effects of LLLT and insole application on pain, function and muscle strength in subjects with stage 2 PTTD. METHODS: Fifty-two subjects with stage 2 PTTD were randomly assigned to the LLLT and insole groups. The foot pain, function and strength of invertor and evertor muscles of the subjects was evaluated before and after treatment, and after 9 months. RESULTS: Significant improvement was observed in the foot function and pain (p< 0.05) in both groups after treatment, but in the 9-month follow-up, the insole group had better values. The increase in 180∘.sec-1 concentric invertor muscle strength was found significant after the treatment and in month-9 as compared to the initial values (p< 0.05). CONCLUSIONS: Both treatments are effective in reducing treating foot pain, as well as improving the function in subjects with stage 2 PTTD. However, at the end of the 9-month follow-up, it was seen that insoles were more effective. Neither method had a clinically important effect on muscle strength.

Orthotic treatment for stage I and II posterior tibial tendon dysfunction (flat foot): A systematic review.

OBJECTIVE: To investigate whether orthotic treatment is effective for the treatment of posterior tibial tendon dysfunction stages I and II (flat foot). DATA SOURCES: Five databases (PubMed, Scopus, PEDro, SPORTDiscus and The Cochrane Library) were searched for potential RCTs from their inception until August 2020. REVIEW METHODS: Only randomised controlled trials (RCT) that included subjects diagnosed with posterior tibial dysfunction in the initial stage and treated with orthotic treatments were selected. The outcomes assessed were whatever symptom related to posterior tibial tendon dysfunction stage I and II. Included RCTs were appraised using the Cochrane collaboration risk of bias tool. RESULTS: Four RCT articles and 186 subjects were included. 75% were at high risk of bias for blinding of participants and personnel. Three different types of conservative treatment were used in the studies: foot/ankle-foot orthoses, footwear and stretching /strengthening exercises. Foot orthoses, together with exercise programmes, seemed to improve the effect of orthotic treatment. Foot orthoses with personalised internal longitudinal arch support were more effective than flat insoles or standard treatments in reducing pain. CONCLUSIONS: The use of orthotic treatment may be effective in reducing pain in the early stages of posterior tibial tendon dysfunction. Further research is needed into individualised orthotic treatment and high-intensity monitored exercise programmes.

Treatment of Stage 4 Flatfoot.

Stage 4 flatfoot represents only a small proportion of flatfoot cases and is likely to become even rarer. The evidence base to guide treatment is limited to case series and expert opinion. Therefore, a pragmatic approach to treatment must be taken. Low-demand individuals may manage well with conservative treatment. Surgical management is complex, likely to require staging, and has a significant complication profile. Patients should be fully informed and understanding of this. First principles of surgery should be followed, including restoring hindfoot and ankle joint alignment, appropriate soft tissue balancing, and optimizing function by limiting arthrodeses and subsequent stiffness.

Regenerative Repair of Volumetric Muscle Loss Injury is Sensitive to Age.

In this study, the influence of age on effectiveness of regenerative repair for the treatment of volumetric muscle loss (VML) injury was explored. Tibialis anterior (TA) VML injuries were repaired in both 3- and 18-month-old animal models (Fischer 344 rat) using allogeneic decellularized skeletal muscle (DSM) scaffolds supplemented with autologous minced muscle (MM) paste. Within the 3-month animal group, TA peak contractile force was significantly improved (79% of normal) in response to DSM+MM repair. However, within the 18-month animal group, muscle force following repair (57% of normal) was not significantly different from unrepaired VML controls (59% of normal). Within the 3-month animal group, repair with DSM+MM generally reduced scarring at the site of VML repair, whereas scarring and a loss of contractile tissue was notable at the site of repair within the 18-month group. Within 3-month animals, expression of myogenic genes (MyoD, MyoG), extracellular matrix genes (Col I, Col III, TGF-ß), and key wound healing genes (TNF-α and IL-1ß) were increased. Alternatively, expression was unchanged across all genes examined within the 18-month animal group. The findings suggest that a decline in regenerative capacity and increased fibrosis with age may present an obstacle to regenerative medicine strategies targeting VML injury. Impact Statement This study compared the recovery following volumetric muscle loss (VML) injury repair using a combination of minced muscle paste and decellularized muscle extracellular matrix carrier in both a younger (3 months) and older (18 months) rat population. Currently, VML repair research is being conducted with the young patient population in mind, but our group is the first to look at the effects of age on the efficacy of VML repair. Our findings highlight the importance of considering age-related changes in response to VML when developing repair strategies targeting an elderly patient population.

"I need somebody who knows about feet" a qualitative study investigating the lived experiences of conservative treatment for patients with posterior tibial tendon dysfunction.

BACKGROUND: Posterior tibial tendon dysfunction is a disabling, chronic, progressive tendon condition that detrimentally affects foot, ankle and lower limb function. Research suggests that posterior tibial tendon dysfunction is poorly recognised and difficult to treat. When posterior tibial tendon dysfunction is diagnosed, the clinician is faced with a weak evidence base and guidelines for the common conservative treatments.to guide their management. Moreover, there are no current evidence-based guidelines for the conservative management of posterior tibial tendon dysfunction. Emerging research suggests that posterior tibial tendon dysfunction not only has a physical impact on the patient, but it also has psychosocial impact on quality of life.Conservative treatments for posterior tibial tendon dysfunction are generally undertaken during early management. The most common are foot orthoses, exercises, bracing, lifestyle changes and injections. Quantitative evidence supporting conservative treatments for posterior tibial tendon dysfunction in relation to function, pain and patient reported outcome measures are reported in the literature.There is a paucity of qualitative research investigating the psychosocial impact of the common treatments for posterior tibial tendon dysfunction. Interpretative phenomenology is concerned with lived experience which is involves the detailed exploration of experience which is embedded within the social and temporal contexts of the lifeworld of the person. The aim of study research is to investigate the lived experience of conservative treatments for patients who have posterior tibial tendon dysfunction using Interpretative Phenomenological Analysis. METHODS: Five participants with posterior tibial tendon dysfunction were purposively recruited from a private podiatry practice and semi-structured interviews were conducted to examine their lived experiences of treatment for posterior tibial tendon dysfunction. The data for this study was collected and analysed using Interpretative Phenomenological Analysis. RESULTS: This research identified three superordinate themes which influenced the lived experience of treatment for these patients (i) adverse experience during the patient journey (ii) treatment burden, and (iii) negative self-concept. CONCLUSION: This study highlights some of what is anecdotally known about the lived experience of treatment for patients with posterior tibial tendon dysfunction, but has never been studied in a qualitative, methodological manner. This study addresses the gap in the qualitative literature. It reveals novel aspects of the lived experience throughout the patient journey, the detrimental impact of treatment burden, loss and negative self-concept. This evidence is important because it highlights the need for a greater understanding of the psychological and social factors that can influence the lived experience of treatment for this group of patients.

Stage I and II Posterior Tibial Tendon Dysfunction: Return to Running?

Posterior tibial tendon dysfunction can be a difficult entity to treat in the athletic population. Understanding the deformity components allows the physician to maximize nonoperative intervention with orthotics and physical therapy. Not all patients improve with nonoperative treatment, and surgical intervention can be successful in minimizing symptoms. Although return to full athletic activity is not universally possible, an active lifestyle is possible for many after surgical reconstruction.

Posterior Tibialis Tendon Dysfunction: Overview of Evaluation and Management.

EDUCATIONAL OBJECTIVES As a result of reading this article, physicians should be able to: 1. Recognize posterior tibialis tendon dysfunction and begin to include it in differential diagnoses. 2. Recall the basic anatomy and pathology of the posterior tibialis tendon. 3. Assess a patient for posterior tibialis tendon dysfunction with the appropriate investigations and stratify the severity of the condition. 4. Develop and formulate a treatment plan for a patient with posterior tibialis tendon dysfunction. The posterior tibialis is a muscle in the deep posterior compartment of the calf that plays several key roles in the ankle and foot. Posterior tibialis tendon dysfunction is a complex but common and debilitating condition. Degenerative, inflammatory, functional, and traumatic etiologies have all been proposed. Despite being the leading cause of acquired flatfoot, it is often not recognized early enough. Knowledge of the anatomical considerations and etiology of posterior tibialis tendon dysfunction, as well as key concepts in its evaluation and management, will allow health care professionals to develop appropriate intervention strategies to prevent further development of flatfoot deformities.

Randomized Controlled Trial Comparing Orthosis Augmented by Either Stretching or Stretching and Strengthening for Stage II Tibialis Posterior Tendon Dysfunction.

BACKGROUND: The value of strengthening and stretching exercises combined with orthosis treatment in a home-based program has not been evaluated. The purpose of this study was to compare the effects of augmenting orthosis treatment with either stretching or a combination of stretching and strengthening in participants with stage II tibialis posterior tendon dysfunction (TPTD). METHODS: Participants included 39 patients with stage II TPTD who were recruited from a medical center and then randomly assigned to a strengthening or stretching treatment group. Excluding 3 dropouts, there were 19 participants in the strengthening group and 17 in the stretching group. The stretching treatment consisted of a prefabricated orthosis used in conjunction with stretching exercises. The strengthening treatment consisted of a prefabricated orthosis used in conjunction with the stretching and strengthening exercises. The main outcome measures were self-report (ie, Foot Function Index and Short Musculoskeletal Function Assessment) and isometric deep posterior compartment strength. Two-way analysis of variance was used to test for differences between groups at 6 and 12 weeks after starting the exercise programs. RESULTS: Both groups significantly improved in pain and function over the 12-week trial period. The self-report measures showed minimal differences between the treatment groups. There were no differences in isometric deep posterior compartment strength. CONCLUSIONS: A moderate-intensity, home-based exercise program was minimally effective in augmenting orthosis wear alone in participants with stage II TPTD. LEVEL OF EVIDENCE: Level I, prospective randomized study.

Posterior tibial tendon dysfunction in the adult: current concepts.

The management of posterior tibial tendon dysfunction in adults has evolved substantially, and controversy persists regarding a specific recommended algorithm for treatment. The current focus is on early diagnosis and treatment of this disorder with joint-sparing surgeries, such as corrective osteotomies and tendon transfers, when nonsurgical modalities have been exhausted. It is helpful to be familiar with the pertinent pathophysiology and diagnostic pearls associated with posterior tibial tendon dysfunction, its treatment options, pertinent literature, and technique tips for the procedures currently being used.

Posterior tibial tendon dysfunction: a silent but disabling condition.

Posterior tibial tendon dysfunction is common and a major cause of flat foot (pes planus) and functional impairment in adults. It is frequently undiagnosed and therefore inappropriately managed. This review raises awareness of posterior tibial tendon dysfunction with the intention of improving patient management.

Diagnosis and treatment of chronic ankle pain.

The differential diagnosis for chronic ankle pain is quite broad. Ankle pain can be caused by intra-articular or extra-articular pathology and may be a result of a traumatic or nontraumatic event. A detailed patient history and physical examination, coupled with judicious selection of the appropriate imaging modalities, are vital in making an accurate diagnosis and providing effective treatment. Chronic ankle pain can affect all age groups, ranging from young athletes to elderly patients with degenerative joint and soft-tissue disorders. It has been estimated that 23,000 ankle sprains occur each day in the United States, representing approximately 1 sprain per 10,000 people per day. Because nearly one in five ankle injuries result in chronic symptoms, orthopaedic surgeons are likely to see patients with chronic ankle pain. Many patients with chronic ankle pain do not recall any history of trauma. Reviewing the management of the various disorders that can cause chronic ankle pain will help orthopaedic surgeons provide the best treatment for their patients.

Disfunción del tibial posterior / No disponible

La disfunción del tibial posterior es una patología adquirida en el adulto de carácter progresivo que cursa con sintomatología dolorosa y el desarrollo de un pie plano valgo o plano.

Tibialis Posterior is an extrinsic muscle of the foot that undergoes so much injuries, often affecting the muscle/tendon unit. We’ll also discuss a clinical case suggesting a conservative treatment by foot orthoses made with Rovalfoam, in order to correct or improve some of the pathologies associated with this dysfunction(AU)

Conservative treatment of tibialis posterior tendon dysfunction--a review.

BACKGROUND: Appropriate conservative treatment is considered essential to address symptoms associated with tibialis posterior tendon dysfunction (TPTD) and prevent its potential long-term disabling consequences. The main aim of this review, undertaken in 2007, was to evaluate the evidence from studies for the effects of conservative treatment modalities in the management of TPTD. This evidence could then be used as a basis for the development of a clinical guideline for the management of the condition. METHODOLOGY: Studies were selected according to specific criteria and evaluated for methodological quality. As preliminary literature searches had identified no randomised controlled trials at the time of the review, studies of lower hierarchy were included. RESULTS: Five uncontrolled observational studies evaluating the outcomes of various orthotic treatments alone or in combination with other therapies were included in the review. Different study designs, methodological quality, population characteristics, interventions and outcome measures were found. DISCUSSION: Limited and poor quality evidence was found in this review regarding the conservative treatment of TPTD. Thus a cause-effect relationship between intervention and outcome could not be established nor an optimal conservative treatment regime for the condition. Further better quality research is warranted in this area to inform practice, particularly as there is no consensus in the literature regarding treatment of this condition.

Patient factors in the selection of operative versus nonoperative treatment for posterior tibial tendon dysfunction.

BACKGROUND: The influence of demographic, medical history, and treatment variables on the maintenance of nonoperative care or progression to operative intervention in Posterior Tibial Tendon Dysfunction (PTTD) was explored. This retrospective study compared demographic, medical history and treatment variables between operative and nonoperative care in subjects with PTTD. MATERIALS AND METHODS: Charts with the ICD-9 codes (726.72, 726.90) and brace distribution records for 2005 and 2006 were used to identify subjects. From these, 166 of 606 charts included documentation of PTTD. Variables were grouped into three categories including demographics (Age, body mass index, gender and working status), medical (stage, symptom duration, pain at initial evaluation, and past treatments) and treatment (initial brace, length of care episode, and brace change). Statistical comparisons between subjects treated nonoperatively and operatively were made. Significant variables were entered into a logistic regression analysis. Accuracy (sensitivity/specificity) was assessed by examining the success of predicting which subjects were treated operatively or nonoperatively. RESULTS: Of the 166 subjects, 125 (75.4%) received nonoperative care and 41 (24.6%) operative care. Nine variables distinguished the operative from the nonoperative group (p<0.05): including BMI, work status, stage, symptom duration, prior orthotic use, prior injection, custom brace, brace changes, and length of care episode. The logistic regression model identified BMI, symptom duration, prior cortisone injections, and prior orthotic use as significant and resulted in a specificity of 95.4% and sensitivity of 38.2%. CONCLUSION: This retrospective analysis provides a patient profile of factors in the success of nonoperative care in PTTD.

Choosing among 3 ankle-foot orthoses for a patient with stage II posterior tibial tendon dysfunction.

STUDY DESIGN: Case report. BACKGROUND: No head-to-head comparisons of different orthoses for patients with stage II posterior tibial tendon dysfunction (PTTD) have been performed to date. Additionally, the cost of orthoses varies considerably, thus choosing an effective orthosis that is affordable to the patient is largely a trial-and-error process. CASE DESCRIPTION: A 77-year-old woman was seen with complaints of abnormal foot posture ('my foot is out'), minimal medial foot and ankle pain, and a 3-year history of conservatively managed stage II PTTD. The patient was not able to complete 1 single-limb heel rise on the involved side, while she could complete 3 on the uninvolved side. Ankle strength testing revealed a mild to moderate loss of plantar flexor strength (20%-31% deficit on the involved side), combined with a 22% deficit in isometric ankle inversion and forefoot adduction strength. To assist this patient in managing her flatfoot posture and PTTD, 3 orthoses were considered: an off-the-shelf ankle-foot orthosis (AFO), a custom solid AFO, and a custom articulated AFO. The patient's chief complaint was partly cosmetic (ìmy foot is outî). As decreasing flatfoot kinematics may unload the tibialis posterior muscle, thus prevent the progression of foot deformity, the primary goal of orthotic intervention was to improve flatfoot kinematics. Given the difficulties in clinical approaches to evaluating flatfoot kinematics, a quantitative gait analysis, using a multisegment foot model, was used. OUTCOMES: In the frontal plane, all 3 orthoses were associated with small changes toward hindfoot inversion. In the sagittal plane, between 2.7 degrees and 6.1 degrees , greater forefoot plantar flexion (raising the medial longitudinal arch) occurred. There were no differences among the orthoses on hindfoot inversion and forefoot plantar flexion. In the transverse plane, the off-the-shelf design was associated with forefoot abduction, the custom solid orthosis was associated with no change, and the custom articulated orthosis was associated with forefoot adduction. DISCUSSION: Based on gait analysis, the higher-cost custom articulated orthosis was chosen as optimal for the patient. This custom articulated orthosis was associated with the greatest change in flatfoot deformity, assessed using gait analysis. The patient felt it produced the greatest correction in foot deformity. Reducing flatfoot deformity while allowing ankle movement may limit progression of stage II PTTD. LEVEL OF EVIDENCE: Therapy, level 4.
