Ankle Evertor and Invertor Strength Training

The aim of this study was to investigate the effects of a 12-week ankle evertor and invertor strength training program performed on a specially designed device, which allows isolated strengthening of evertor and invertor muscles. Outcome measures included isometric ankle torque, EMG activity of six tibial muscles, muscle coactivation, and kinematic parameters during three walking conditions. This trial was retrospectively registered. The study was conducted in 2017 as part of a doctoral dissertation at the Faculty of Sport, University of Ljubljana, prior to the authors' awareness of prospective registration requirements.

Auditory Biofeedback Gait Training Individuals With Chronic Ankle Instability

The goal of this randomized clinical controlled trial is examine the effects of gait training with auditory biofeedback (AudFB) on gait biomechanics, clinical measures of ankle joint health, and patient-centered outcomes. The following specific aims will achieve this objective: * Specific Aim 1: Determine if a 6-week gait training with AudFB intervention improves lower extremity biomechanics compared to a Control condition in participants with CAI. * Specific Aim 2: Determine if a 6-week gait training with AudFB reduces talar cartilage deformation compared to a Control condition in participants with CAI. * Specific Aim 3: Determine if a 6-week gait training with AudFB reduces episodes of ankle giving-way and reduces self-perceived severity of symptoms relative to a Control condition in participants with CAI. Participants will: * Complete 12 intervention sessions over a 6-week period of walking, ruck marching, and runninig. * Complete testing sessions before and after the intervention, then after 6 and 12-months following the intervention.

Observational Study to Evaluate Safety and Performance of the Total Ankle Prosthesis, EasyMove®

This study is a post-market clinical follow-up conducted in order to collect long-term data on safety and performance of the EasyMove prosthesis, which is intended to be implanted in case of total ankle replacement, when used in real life conditions according to the instructions for use.

A Cohort Study of Bioabsorbable Screws for Syndesmosis Fixation Fixation in Ankle Fracture

The investigators aim to evaluate the fixation of the ankle syndesmosis in appropriate ankle fractures with bioabsorbable screws. Ankle fractures are common, and a proportion of them involve both fracture of the bone and also disruption of the syndesmosis, a strong ligamentous complex connecting the distal fibula and tibia. If left without fixation this causes a high incidence of pain and early arthritis. The most common technique for fixation of this syndesmosis involves the use of the same type of metal screws used to fix the fractured bones. As the syndesmosis permits small degrees of movement in normal subjects, fixation of this with metal usually leads to screw breakage and, or pain. It is common practice to remove these screws after a period of time once the syndesmosis has healed in the correct position. Bioabsorbable screws have the advantage of allowing small increments of movement, and also resorb naturally therefore do not have to be removed with a second surgical procedure. They are used in other centres worldwide, and the investigators therefore seek to evaluate syndesmosis fixation with them in their unit. The investigators would aim to recruit patients who have a syndesmotic injury requiring fixation, and who can consent to participating. They would undergo an identical surgical procedure to the standard current practice, apart from using a bioabsorbable screw in exchange for the metallic screw for syndesmosis fixation. All other components would remain unchanged, as would post operative protocol and management. To evaluate the fixation the investigators would use a limited CT scan (equivalent of about 3 months background radiation) after the time of fixation and at one year. This will help to assess the maintenance of reduction of the syndesmosis with time. The investigators would also assess patient reported outcome measures and pain scores, length of procedure and intraoperative radiation levels, weight bearing distribution tests, as well as any complication that may arise.

Exparel Use in Peripheral Nerve Blocks and Local Infiltration for Foot and Ankle Surgery

Liposomal Bupivacaine (Exparel) has been recently studied as the active agent utilized in various nerve block. Due to its liposomal form allowing for extended delivery, Exparel has been used in various peri-operative nerve blocks among multiple orthopaedic specialties in hopes of achieving improved pain control and decreased opioid use. This study compares the efficacy and effect on opioid use of peripheral nerve blocks and local infiltration with and without Exparel in patients undergoing foot and ankle surgery.

Assessment of Medrol Dosepak to Reduce Opioid Consumption in Foot and Ankle Surgical Patients

This clinical trial aims to determine the effects of a 6-day low-dose methylprednisolone course on pain, nausea, and total opioid consumption in patients undergoing foot and ankle surgeries. The secondary objective of the study is to determine and monitor the effects of the course on complications following surgery and patient-reported outcomes

Postoperative Complications of Ankle Arthroscopy

The goal of this clinical trial is to describe complications that occurred in the year following surgery, based on follow-up surgical consultations and physical therapy sessions. The target population is any adult patient who has undergone ankle surgery performed under arthroscopy. Primary outcome is description of all complications occurring within one year following ankle arthroscopy. This description will be based on clinical and functional examinations performed by surgeons and physical therapists. Participants will be regularly monitored by the surgeon and physical therapist (15 days postoperative, 3 months, 6 months, and 1 year). They will complete self-assessment questionnaires and undergo functional physical therapy tests, including ALR RSI, FAAM AVQ, FAAM Sport, CAIT, and Ankle Go.

The Effect of Taping on Plantar Pressure Distribution in Players With Chronic Ankle Instability

The goal of this study is to investigate whether there exists a difference in baropdometric readings of plantar pressure between individuals with chronic ankle instability and normal health individuals, in addition another goal of this study is to investigate the effect of rigid taping vs. kinesio taping on plantar pressure distribution as well as stability markers in individuals with chronic ankle instability. The main questions aimed to answer are: 1. Is there a difference in plantar pressure distribution between individuals with chronic ankle instability and individuals without chronic ankle instability? 2. What effect do rigid and kinesio taping have on plantar pressure distribution and ankle stability markers? 3. Which tape affects plantar pressure distribution and ankle stability better? Participants will: Firstly be divided into two macro groups, one with chronic ankle instability and one without, with an observational part of the study to be carried out to investigate the differences in plantar pressure between both groups. Secondly, the group with chronic ankle instability will be divided into two micro groups one receiving rigid taping and the other receiving kinesio taping, and the immediate effects of these tapes in terms of plantar pressure and ankle stability will be recorded and compared before and after within groups, and after between both groups.
