Introduction: Charcot neuroarthropathy (CN) can result in fractures and dislocations of the foot and ankle in individuals with diabetes and neuropathy, leading to ulceration, amputation and a poor quality of life. Additional episodes of acute CN can lead to extended periods of physical and psychosocial distress. The aim of this scoping review was to identify and synthesise the evidence relating to factors associated with the development of recurrent and contralateral Charcot neuroarthropathy (CN) in individuals with diabetes.

Introduction: Midfoot osteoarthritis (OA) is a painful and disabling condition. Arch contouring foot orthoses have been recommended for midfoot OA, yet there is no high-quality evidence from randomised controlled trials to support their use. This clinical trial aims to evaluate the efficacy of arch contouring foot orthoses for midfoot OA.

Background: Osteoarthritis (OA) affecting the first metatarsophalangeal joint (hallux rigidus) is common and painful. Several non-surgical treatments have been proposed; however, few have been adequately evaluated. Since the original 2010 review, several studies have been published necessitating this update.

Background: People with plantar heel pain (PHP) have reduced foot and ankle muscle function, strength and size, which is frequently treated by muscle strengthening exercises. However, there has been little investigation of what exercises are used and there is no sound evidence base to guide practice. This study aimed to develop a consensus-driven progressive muscle strengthening program for PHP.

Objective: We aimed to explore the relationship between bone shape and radiographic severity in individuals with first metatarsophalangeal joint osteoarthritis (first MTP joint OA).

Methods: Weightbearing lateral and dorsoplantar radiographs were obtained for the symptomatic foot of 185 participants (105 females, aged 22 to 85 years) with clinically diagnosed first MTP joint OA. Participants were classified into none/mild, moderate, or severe categories using a standardized atlas.

Background: Removable cast walkers (RCWs), with or without modifications, are used to offload diabetes-related foot ulcers (DRFUs), however there is limited data relating to their offloading effects. This study aimed to quantify plantar pressure reductions with an RCW with and without modification for DRFUs.

Methods: This within-participant, repeated measures study included 16 participants with plantar neuropathic DRFUs.

This study aimed to compare health-related quality of life (HRQoL) in people with and without plantar heel pain (PHP). This was a cross-sectional observational study that compared 50 adult participants with PHP to 25 participants without PHP who were matched for age, sex and body mass index (BMI). HRQoL measures included a generic measure, the Short Form 36 version 2 (SF-36v2), and foot-specific measures, including 100 mm visual analogue scales (VASs) for pain, the Foot Health Status Questionnaire (FHSQ), and the Foot Function Index-Revised (FFI-R).

Article Synopsis
  • Variable eligibility criteria in studies of plantar heel pain may limit the generalization of meta-analyses due to inconsistencies in participant selection.
  • A systematic review analyzed 214 studies, revealing significant variation in how age, BMI, symptom duration, and pain level were defined, with some criteria appearing in many different formats.
  • The findings suggest that the way eligibility criteria are set can influence the characteristics of participants, indicating a need for standardized criteria to improve comparability across studies.

Background: Activity and footwear may be associated with plantar heel pain (PHP), however both factors have rarely been investigated. The aim of this study was to investigate activity and footwear characteristics in PHP while controlling for important confounders.

Method: This cross-sectional observational study compared 50 participants with PHP to 25 participants without PHP who were matched for age, sex and body mass index.

Background: Medical imaging can be used to assist with the diagnosis of plantar heel pain. The aim of this study was to synthesise medical imaging features associated with plantar heel pain.

Methods: This systematic review and meta-analysis conducted searches in MEDLINE, CINAHL, SPORTDiscus, Embase and the Cochrane Library from inception to 12th February 2021.

Background: Morton's neuroma is a common condition that routinely presents in podiatric practice. The aim of this study was to systematically synthesize the evidence relating to the effectiveness of a corticosteroid injection for Morton's neuroma.

Methods: Studies with a publication date of 1960 or later were eligible, and searches were performed within the Turning Research Into Practice database; the Cochrane Central Register of Controlled Trials; the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register; MEDLINE (Ovid); PubMed; Embase; Cumulative Index to Nursing and Allied Health Literature; and the gray literature.

Introduction/objectives: First metatarsophalangeal joint (MTP) joint osteoarthritis (OA) is prevalent, although the pathology of this condition is poorly understood. This study aimed to determine if there were differences in magnetic resonance imaging (MRI) characteristics of the first MTP joint between individuals with and without first MTP joint OA.

Method: This cross-sectional study compared 22 participants with first MTP joint OA to 22 control participants without first MTP joint OA (matched for age, sex, and body mass index).

Background: Studies have described general practitioner (GP) management of plantar heel pain from some countries; however, there is limited information from Australian general practice.

Objectives: To describe patient and GP characteristics, and management actions for plantar heel pain in Australian general practice.

Design: Secondary analysis of data from the Bettering the Evaluation and Care of Health (BEACH) dataset.

Foot posture and ankle joint dorsiflexion have long been proposed to be risk factors for plantar heel pain, however body mass may be a confounder when investigating these factors. The aim of this study was to determine if clinical measures of foot posture and ankle joint dorsiflexion differ in adults with and without plantar heel pain after accounting for body mass. This was a cross-sectional observational study that compared 50 participants with plantar heel pain to 25 control participants without plantar heel pain who were matched for age, sex and body mass index.

Purpose: This study compared the differences in foot dimensions between children with and without Down syndrome using three-dimensional (3D) foot scans.

Methods: 51 children with and 51 children without Down syndrome had a 3D scan taken of their right foot to compare the absolute and normalised (for height or foot length) measurements.

Results: Normalised foot length was shorter in children with Down syndrome (MD -11.

Objective: To evaluate the efficacy of carbon-fibre shoe-stiffening inserts in individuals with first metatarsophalangeal joint osteoarthritis.

Design: This was a randomised, sham-controlled, participant- and assessor-blinded trial. One hundred participants with first metatarsophalangeal joint osteoarthritis received rehabilitation therapy and were randomised to receive either carbon fibre shoe-stiffening inserts (n = 49) or sham inserts (n = 51).

Background: Foot orthoses and corticosteroid injection are common interventions used for plantar heel pain, however few studies have investigated the variables that predict response to these interventions.

Methods: Baseline variables (age, weight, height, body mass index (BMI), sex, education, foot pain, foot function, fear-avoidance beliefs and feelings, foot posture, weightbearing ankle dorsiflexion, plantar fascia thickness, and treatment preference) from a randomised trial in which participants received either foot orthoses or corticosteroid injection were used to predict change in the Foot Health Status Questionnaire foot pain and foot function subscales, and first-step pain measured using a visual analogue scale. Multivariable linear regression models were generated for different dependent variables (i.

  • The study aimed to compare the effectiveness of heel lifts versus calf muscle eccentric exercise in treating mid-portion Achilles tendinopathy.
  • Conducted at La Trobe University with 100 participants, the study measured improvement through the VISA-A questionnaire after 12 weeks.
  • Results showed heel lifts led to a greater improvement in VISA-A scores (mean difference of 9.6 points) than eccentric exercises, but the difference was not significant enough to confirm a clinically meaningful advantage.
