Comparison of Anesthetic Techniques for Early Recovery After Ankle Arthroscopy

Ankle arthroscopy is increasingly performed as a day-case procedure, making rapid recovery and efficient discharge critical. Anesthetic technique substantially influences postoperative recovery, yet high-quality evidence comparing anesthetic strategies in ankle arthroscopy is limited. This multicenter randomized trial compares total intravenous anesthesia with propofol plus peripheral nerve block (PNB), general anesthesia plus PNB, and spinal anesthesia, with PACU-I recovery time as the primary outcome. Secondary outcomes include postoperative pain, opioid consumption, hospital length of stay, adverse events, recovery quality, satisfaction, limb weakness, and intraoperative hemodynamics.

the Efficacy of Hyperbaric Oxygen on Acute Ankle Sprain

Investigators recruited 208 patients with acute ankle sprain who were from the Rehabilitation Department of the Second Affiliated Hospital of Zhejiang University, School of Medicine from January 2026 to November 2028. Perform the improvement in AOFAS scores and Baird-Jackson ankle scores study and Rehabilitation assessments followed up after 3 years.

NMES With PNF for Ankle Sprain Rehabilitation

Ankle sprains are one of the most common sports injuries. In some people, they can lead to chronic ankle problems that affect daily life and sports performance. In this study, we want to see if combining neuromuscular electrical stimulation (NMES) with proprioceptive neuromuscular facilitation (PNF) can help improve these problems. We plan to recruit 60 participants, with 30 in the experimental group and 30 in the control group. The experimental group will receive PNF stretching with NMES, while the control group will only do PNF stretching. Both groups will have training three times a week for four weeks (12 sessions in total). We will test participants before and after the program, looking at pain, balance, range of motion, proprioception, strength, joint mobility, and functional limitations. We expect that 12 sessions will help improve chronic ankle problems, and that NMES combined with PNF will be more effective than PNF alone.

Surgical Management of Lateral Ankle Instability: Modified Broström-Gould Versus Arthroscopic Allograft Reconstruction of the Anterior Talofibular and Calcaneofibular Ligaments.

Primary Objective: To clarify whether arthroscopic reconstruction with allograft provides tangible benefits over the modified open Broström-Gould technique, or if both are equivalent in efficacy and safety. The clinical AOFAS scale will be used for assessment. Secondary Objectives: To determine if there are differences in health outcomes and patient-perceived pain using the specific SP-36 scale and verbal numeric rating scale (VNRS). Additionally, to assess differences in postoperative complication rates and time to return to daily life activities between the two surgical techniques. Study Design: Prospective, randomized, controlled clinical trial with two parallel groups stratified by age and functional demand. Condition or Disorder Being Studied: Chronic lateral ankle instability. Study Population and Sample Size: The target population includes subjects diagnosed with chronic lateral ankle instability. The study population consists of patients diagnosed in the Orthopedics consultations at Hospital Infanta Elena who meet the inclusion and exclusion criteria. Based on sample size calculations, a total of 36 patients will be recruited. However, due to the prospective nature and stratification by epidemiological and functional variables, the sample size may be increased to ensure comparable groups in each stratum. Study Timeline and Estimated Completion Date: The study is expected to begin in the third quarter of 2025. Recruitment is estimated to last 24 months, with a follow-up period of 12 months, for a total duration of 3 years, ending in the third quarter of 2028.

Validity and Reliability of Calf Raise Tests in Patients With Achilles Tendon Rupture and Lateral Ankle Sprain

This study aims to evaluate the validity and reliability of clinically used Calf Raise Test parameters (collected with the "the Calf Raise App") between patients with Lateral Ankle Sprain or Achilles Tendon Repair and healthy controls.

Validation of a Portable Ankle Arthrometer

The purpose of this study is to assess the validity and reliability of a prototype portable ankle arthrometer in various populations. There are two aims to this study. Aim 1 will look to determine the reliability and validity of a prototype portable ankle arthrometer on young adults with no history of ankle sprain, copers, and young adults with chronic ankle instability. It is hypothesized that the prototype portable ankle arthrometer will be a valid and reliable tool to assess joint laxity across the three different populations. Aim 2 will look to determine the validity of a prototype portable ankle arthrometer in young adults with an acute ankle sprain across multiple timepoints in their first month post injury. It is hypothesized that the prototype portable ankle arthrometer will be a valid tool to assess joint laxity at three different timepoints for the same individual.

Semiconductor Embedded Socks for Ankle Sprains

The goal of this clinical trial is to determine if semiconductor fabric embedded in socks can improve healing after non operative ankle sprains. The main questions it aims to answer are: 1. How does semiconductor embedded sock effect outcomes in patients undergoing rehabilitation from ankle injury? 2. How does semiconductor embedded socks effect injury symptoms and function throughout the course of treatment? Researchers will compare semiconductor embedded socks with typical compression socks to determine differences in healing. Participants will be given the socks and be asked to wear them throughout the healing process and record symptoms and functional measures.

Efficacy of Tecar Device With Exercises in Ankle Sprain

The goal of this clinical trial is to evaluate the effect of applying TECAR therapy during active therapeutic exercises on pain, ankle dynamic balance, proprioception, and daily function in patients with acute ankle sprain. the main questions it aims to answer are: * Does there is a significant effect of applying TECAR therapy during active exercise after acute lateral ankle sprain on Pain? * Does there is a significant effect of applying TECAR therapy during active exercise after acute lateral ankle sprain on balance? * Does there is a significant effect of applying TECAR therapy during active exercise after acute lateral ankle sprain on proprioception? * Does there is a significant effect of applying TECAR therapy during active exercise after acute lateral ankle sprain on daily function? The patients will be randomly divided into two groups. The control group (A) will receive the conventional therapy which is ankle and subtalar ROM in a pain-free range, calf muscle stretch, ankle strengthening exercises against resistance bands in all directions, weight-bearing exercise, forward lunges, bilateral and unilateral squats, bilateral and unilateral heel raises against bodyweight resistance, and balance training. The experiment group (B) will receive conventional therapy with TECAR therapy application during active therapeutic exercises. Treatment will be for 4 weeks with 2 sessions per week. TECAR application will be 20 mins per session (10 mins capacitive and 10 mins resistive). To the best of the researchers' knowledge, no study has proved the effects of applying TECAR therapy during active therapeutic exercises after an acute lateral ankle sprain has yet been done. Thus, the purpose of the present study was to prove if there an effect of applying TECAR therapy during active therapeutic exercises included in the conventional physiotherapy (PRICE with therapeutic exercises) and conventional physiotherapy alone on pain, ankle dynamic balance, proprioception, and daily function in subjects with an acute lateral ankle sprain.

Comparison of MBR + Suture Tape and MBR for CLAI in GJL Cases: A Prospective Cohort Study

GJL is a risk factor for postoperative recurrent instability following an MBR for CLAI. Additional suture tape augmentation has been suggested to provide more strength and stability. However, the outcomes of the MBP with suture tape augmentation were unknown, which requires further exploration.

Computed Tomography with Stress Maneuvers for Evaluation of Distal Tibiofibular Syndesmosis Instability (CTMETS)

The main aim of this study was to investigate which strategy can diagnose more accurately syndesmotic instability among an existing index test (ankle CT in neutral position) and two new add-on index tests (ankle CT in a stress position with extended-knees and ankle CT in a stress position with flexed-knees). This study hypothesized that the two add-on ankle CT with stress maneuvers (CTSM) have a more accurate capability of diagnosing syndesmotic instability than ankle CT in a neutral position (CTNP) alone. The secondary objective is to investigate the participants' disability outcomes by applying the Foot and Ankle Ability Measure questionnaire.

Topical Treatments for Ankle Sprains

Our aim was to evaluate the effects of topical analgesic drugs on rapid recovery of joint functions and pain relief in acute ankle injuries. A total of 100 patients were included in the study and divided into 2 groups as Diclofenac and Etofenamate. The pain scores of the patients were evaluated with the Numeric Rating scale and Wong-Baker scale before and after treatment. Dorsiflexion and plantarflexion active joint movements were measured with a hand-held goniometer for joint function before and after treatment. We found that ankle sprains were more common in men. In our study, we found that both topical analgesics were effective in improving joint movements and reducing pain.
