CASE: We report a 67-year-old healthy man who sustained bilateral hyper-plantarflexion injuries falling off a ladder that resulted in bilateral tibialis anterior tendon tears one month prior to presentation. His injuries were effectively managed with bilateral delayed operative treatment. After non-weightbearing for three months, the patient was subsequently permitted to full weight bear in CAM boots for three months. At three-year follow-up he was fully functional with excellent Foot and Ankle Ability Measure (FAAM scores)...

The surface effects on running biomechanics have been greatly investigated. However, the effects on rearfoot strike runners remain unknown. The purpose of this study was to investigate the effects of surfaces on the running kinematics, kinetics, and lower-limb stiffness of habitual rearfoot strikers. Thirty healthy male runners were recruited to run at 3.3 ± 0.2 m/s on a customized runway covered with three different surfaces (artificial grass, synthetic rubber, or concrete), and their running kinematics, kinetics, and lower-limb stiffness were compared...

PURPOSE: The purpose of this study was to investigate the position of the femur relative to the tibia throughout range of motion in the osteoarthritic knee to evaluate knee kinematics and assess its relationship with the degree of varus deformity. METHODS: In this study, 116 preoperative knees with varus deformity were evaluated using a navigation system. The internal-external, anteroposterior, and mediolateral positions of the femur relative to the tibia were measured at maximum extension, 15°, 30°, 45°, 60°, 90°, 105°, and 120°, and maximum flexion angles...

PURPOSE: It is now well established that the coronal anatomy of the lower limb is highly variable both in non-arthritic subjects and subjects undergoing total knee arthroplasty (TKA). Two new classifications were recently described independently, but never compared: functional knee phenotypes classification and coronal plane alignment of the knee (CPAK) classification. The hypothesis of this study was that there was a significant difference between the values of the hip-knee-ankle angle (HKA) and the arithmetic hip-knee-ankle angle (aHKA) measures in the same patient at the time of TKA...

BACKGROUND: Assessing patient's risk of infection is fundamental for prevention of periprosthetic joint infection (PJI) after total ankle arthroplasty (TAA). The Mayo Prosthetic Joint Infection Risk Score (Mayo Score) is based on data from total hip and knee arthroplasty and has not been validated for application for TAA. METHODS: A total of 405 consecutive TAA cases were followed for 6 months for PJI. Individual patients' Mayo Scores were calculated and analyzed with logistic regression and receiver operating characteristic (ROC) for predictability for PJI...

BACKGROUND: The posterolateral approach to the ankle allows for reduction and fixation of the posterior and lateral malleoli through the same surgical incision. This can be accomplished via 1 or 2 surgical "windows." The purpose of this study is to compare outcomes including wound complications following direct fixation of unstable rotational ankle fracture through the posterolateral approach using either 1 or 2 surgical windows. METHODS: One hundred sixty-four patients with bi- or trimalleolar ankle fractures treated using the single-window posterolateral approach (between the peroneal tendons and the flexor hallucis longus [FHL]) or the 2-window technique (between the peroneal tendons and the FHL for posterior malleolus fixation; lateral to the peroneal tendons for fibula fixation) were reviewed for demographics, radiographic details, and clinical outcomes...

Human walking appears complicated, with many muscles and joints performing rapidly varying roles over the stride. However, the function of walking is simple: to support body weight as it translates economically. Here, a scenario is proposed for the sequence of joint and muscle actions that achieves this function, with the timing of muscle loading and unloading driven by simple changes in geometry over stance. In the scenario, joints of the legs and feet are sequentially locked, resulting in a vaulting stance phase and three or five rapid 'mini-vaults' over a series of 'virtual legs' during the step-to-step transition...

Nocturnal blood pressure (BP) surge in seconds (sec-surge), which is characterized as acute transient BP elevation over several tens of seconds is induced by obstructive sleep apnea (OSA) and OSA-related sympathetic hyperactivity. The authors assessed the relationship between sec-surge and arterial stiffness in 34 nocturnal hypertensive patients with suspected OSA (mean age 63.9 ± 12.6 years, 32.4% female). During the night, they had beat-by-beat (BbB) BP and cuff-oscillometric BP measurements, and brachial-ankle pulse wave velocity (baPWV) was assessed as an arterial stiffness index...

A surgical scar with adhesions to the underlying fascia and periosteum caused radiating pain to different parts of the scar. Abdominal pain is a common complication of surgical scars, but surgical scar associated with extremity pain is rare. A 75-year-old man had a gait disturbance due to right sciatica-like pain from the thigh to the lower leg for >10 years. He also had mild ankle pain due to osteoarthrosis. The medical history was significant for an ankle injury diagnosed as a sprain and intra-articular small fracture, for which he underwent resection of the bone fragment from the anterior aspect 14 years ago...

PURPOSE: Patellar height is a risk factor for patellar instability, correlated with the tibia length/femur length (T/F) ratio. This study aimed to explore the changes in the T/F ratio in patients with patella instability and the potential correlation with the morphology of the patellofemoral joint and extensor moment arm. METHOD: A retrospective analysis was performed to assess the ratio of lower limb length morphological characteristics of the patellofemoral by full weight-bearing long-leg standing radiographs, magnetic resonance imaging, and computed tomography in 75 patients with patellar instability and 75 participants from a randomly selected control group from January 2020 to September 2021...

Measuring and predicting accurate joint angles are important to developing analytical tools to gauge users' progress. Such measurement is usually performed in laboratory settings, which is difficult and expensive. So, the aim of this study was continuous estimation of lower limb joint angles during walking using an accelerometer and random forest (RF). Thus, 73 subjects (26 women and 47 men) voluntarily participated in this study. The subjects walked at the slow, moderate, and fast speeds on a walkway, which was covered with 10 Vicon camera...

Artificial tendons may be valuable clinical devices for replacing damaged or missing biological tendons. In this preliminary study, we quantified the effect of polyester-suture-based artificial tendons on movement biomechanics. New Zealand White rabbits underwent surgical replacement of either the Achilles (n = 2) or tibialis cranialis (TC, n = 2) biological tendons with artificial tendons. Once pre-surgery and weekly from 2 to 6 weeks post-surgery, we quantified hindlimb kinematics and ground contact pressures during the stance phase of hopping gait...

OBJECTIVE: In a large-scale population cardiovascular screening programme, peripheral artery disease (PAD) and hypertension would ideally be rapidly assessed using a single device. The ankle-brachial pressure index (ABPI) is calculated by comparing the ankle and brachial blood pressure (BP). However, it is currently unclear whether brachial BP measurements provided by automated PAD screening systems are sufficiently accurate for simultaneous hypertension screening. METHODS: Two portable PAD screening devices, the MESI ABPI MD and Huntleigh's Dopplex ABIlity, were evaluated following the European Society of Hypertension International Protocol (ESH-IP) Revision 2010 using a mercury-free sphygmomanometer as a reference device...

Temporary lower-limb immobilisation following injury is a risk factor for the development of venous thromboembolism (VTE), which encompasses deep vein thrombosis (DVT) and pulmonary embolism. However, patients are not always risk-assessed for VTE in clinical practice and there is a lack of consensus among healthcare professionals on whether thromboprophylaxis should be offered and to whom. This article uses the fictional case study of a patient with an ankle fracture to explore the literature and guidance on VTE risk assessment and thromboprophylaxis in adults presenting to emergency settings with lower-limb trauma requiring immobilisation...
