posterior tibial tendon dysfunction

BACKGROUND: Posterior tibialis tendon dysfunction (PTTD) is a chronic degenerative musculoskeletal disorder causing a progressive ankle complex and arch collapse altering lower limb biomechanics. However, biomechanical changes associated with stage 1 and 2 PTTD need to be better characterized during walking to guide clinical recommendations and improve non-operative treatments. RESEARCH QUESTION: What are the lower limb kinematic and kinetic differences between individuals with stage 1 (PTTD1), individuals with stage 2 PTTD (PTTD2) and healthy counterparts during gait? METHODS: Sixteen PTTD1, 11 PTTD2 and 20 healthy controls were included in this multicentric case-control study to compare their lower limb gait biomechanics...

BACKGROUND: Supination resistance is a clinical outcome that estimates the amount of external force required to supinate the foot. A greater supination resistance may indicate greater loads on structures responsible for generating internal supination moments across the subtalar joint during static and dynamic tasks. As such, greater supination resistance may be an expected finding in medial foot and ankle musculoskeletal disorders, such as plantar fasciopathy (PF) and posterior tibial tendon dysfunction (PTTD), whereas reduced supination resistance may be present in lateral ankle disorders, such as chronic ankle instability (CAI)...

Numerous surgical procedures for the treatment of posterior tibialis tendon (PTT) dysfunction have been developed, including tendon transfers, osteotomies, and arthrodesis. Among these methods, foot and ankle surgeons most frequently use flexor digitorum longus (FDL) tendon transfer in conjunction with medial translational osteotomy of the calcaneus. Formerly, some less invasive techniques have been described to reduce surgical-related complications after FDL tendon transfer. Herein, we introduced a new modification of short-stump FDL tendon fixation to the navicular bone and reported the functional outcomes of the current technique in a patient with PTT dysfunction...

OBJECTIVE: To perform a systematic review to examine the diagnostic accuracy of magnetic resonance imaging, ultrasonography, and radiography in the evaluation of posterior tibial tendon dysfunction (PTTD). MATERIALS AND METHODS: Medline, Scopus, Embase, and The Cochrane Central Register of Controlled Trials (CENTRAL) were searched for relevant studies through April 2023. The study quality was assessed using the QUADAS-2 scoring system. RESULTS: Of the initial 634 studies, 12 studies met the quality criteria and were included, with 645 PTTs evaluated with MRI, 133 with US, and 97 with radiography...

Triple arthrodesis is a time-tested procedure toward primary salvage in the context of posterior tibial tendon dysfunction, symptomatic rigid and severe hindfoot malalignment, end-stage degenerative and posttraumatic arthritis, and sequelae of paralytic diseases. Today, the indication for hindfoot arthrodesis is applied to correct painful deformities and arthritic joints, such as advanced cases of adult-acquired flatfoot secondary to ligament collapse and insufficiency of the posterior tibial tendon. Although the triple arthrodesis is an effective and reliable outcome procedure, the popularity of a medial double arthrodesis has increased...

OBJECTIVES: The purpose of this study was to assess the safety of ultrasound-guided corticosteroid injections into the posterior tibial tendon sheath for posterior tibialis tendinopathy. Secondary outcomes include duration of pain relief, amount of pain relief, need for repeat injections and progression to surgery. METHODS: We retrospectively reviewed all patients in our electronic medical record who underwent a posterior tibial tendon sheath (PTTS) steroid injection between 2015 and 2020 for the diagnosis of posterior tibial tendon dysfunction and/or posterior tibialis tendon insufficiency, and/or ankle pain...

The posterior tibial tendon is a gliding tendon which courses around the medial malleolus and fails in Posterior Tibialis Tendon Dysfunction (PTTD) leading to a flat foot deformity. Distal tibial bone spurs have been identified as a secondary sign of PTTD although they have not been quantified in detail. The aim of this study was to assess the association of tendon dysfunction with the bony morphology of the tibial retro-malleolar groove. We performed a retrospective review of the clinical presentation, plain radiographs and 103 Magnetic Resonance Imaging (MRI) scans in 82 consecutive patients with PTTD compared with a non-PTTD group...

OBJECTIVES: This study aimed to determine outcome domains of importance to patients living with foot and ankle disorders in rheumatic and musculoskeletal diseases (RMDs), by exploring the symptoms and impact of these disorders reported in existing qualitative studies. METHODS: Six databases were searched from inception to March 2022. Studies were included if they used qualitative interview or focus group methods, were published in English, and involved participants living with RMDs (inflammatory arthritis, osteoarthritis, crystal arthropathies, connective tissue diseases, and musculoskeletal conditions in the absence of systemic disease) who had experienced foot and ankle problems...

A 77-year-old man with diabetes presented to our hospital because of left toe gangrene, requiring infrapopliteal revascularization. The patient was on hemodialysis for renal dysfunction. The great saphenous veins had been used for a previous coronary artery bypass. Hence, the small saphenous vein was applied in a popliteal-to-distal posterior tibial artery bypass. The vein graft was passed under the Achilles tendon to reduce graft length, preventing external compression around the ankle. We performed minor amputation and provided negative pressure wound therapy to promote ulcer healing...

Adult acquired flatfoot is a progressive deformity of the foot and ankle, which frequently becomes increasingly symptomatic. The posterior tibial tendon is most commonly associated with the deformity. A targeted physical examination with plain film radiographs is the recommended initial assessment, which will further guide a physician toward procuring more advanced imaging or toward surgical intervention. In this chapter the authors review the current literature of their approach to the treatment of the ankle in end stage of adult acquired flatfoot deformity...

The adult-acquired flatfoot is a complex multiplanar deformity that requires the foot and ankle surgeon to balance soft tissue, correct hindfoot valgus, and address instability of the medial column. The naviculocuneiform joint is historically underappreciated in regard to its involvement in medial column instability relative to the talonavicular and tarsometatarsal joints. Proper clinical and radiographic evaluation of the medial column, specifically evaluating for deformity at each medial column joint, will allow the surgeon to ensure correction of deformity and decrease the recurrence of instability or failure of the reconstruction...

Posterior tibial tendon disfunction is one of the most commonly treated foot and ankle entities. Surgical treatment may consist of various components and is often performed on an a-la-carte basis. Commonly, joint preservative surgery for posterior tibial tendon dysfunction invariably involves one or more osteotomies of the calcaneus. This article evaluates the current existing evidence guiding providers in the selection of single or double calcaneal osteotomies.

Equinus plays an important role in flatfoot deformity. Proper evaluation and surgical management are critical to comprehensively treat and successfully resolved patients' symptoms. We have discussed the cause, evaluation, and some of the common surgical options. Each procedure has its inherent benefits and risks. It is imperative that the foot and ankle surgeon identify and include these procedures as part of the complete reconstructive surgery.

In this article, the authors present essential anatomy in the presence of the postural flat foot. There is a recognition of static versus dynamic stabilizers of the foot. In the continuum of the collapsed foot, there is an exploration of anatomic and pathologic changes. Providing this fundamental knowledge will allow the reader to appreciate the disease process to establish a prognosis and consider treatment alternatives.

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...

BACKGROUND: The purpose of this study was not only to examine the attachment site but also to quantify the effect of the tibialis posterior tendon (TPT) on each attachment site by examining the surface area of the attachment region. METHODS: We examined 100 feet from 50 Japanese cadavers. The TPT attachment to the navicular bone (NB), medial cuneiform bone (MCB), and lateral cuneiform bone (LCB) were set as the main attachment sites (Type I). The attachment seen in Type I with the addition of one additional site of attachment was defined as Type II...

BACKGROUND: Symptomatic progressive collapsing foot deformity (PCFD) is frequently treated with reconstructive surgery. Multiple studies have documented successful treatment based on improvements in symptoms and physical examination findings. However, it is not well-established whether there are corresponding improvements in gait function following surgical treatment for PCFD. METHODS: A systematic review of biomechanical outcomes of treatments for flexible PCFD was conducted on PubMed...

Posterior tibial tendon dysfunction (PTTD) and tarsal tunnel syndrome (TTS) are debilitating conditions reported to occur after ankle sprain due to their proximity to the ankle complex. The objective of this study was to investigate the incidence of PTTD and TTS in the 2 years following an ankle sprain and which variables are associated with its onset. In total, 22,966 individuals in the Military Health System diagnosed with ankle sprain between 2010 and 2011 were followed for 2 years. The incidence of PTTD and TTS after ankle sprain was identified...

Pes planovalgus is a multiplanar deformity consisting of a combination of hindfoot valgus, collapse of the medial longitudinal arch, forefoot varus, and forefoot abduction. This deformity is often associated with posterior tibial tendon dysfunction. Collapse of the medial longitudinal arch increases stress to the static stabilizers of the medial column including the deltoid ligament, spring ligament, plantar fascia, plantar and talocalcaneal interosseous ligaments, as well as the talonavicular and naviculocuneiform capsules...
