Filter by:The current study involves a prospective interventional study that primarily intends to compare foot joint loadings of participants with chronic ankle instability (CAI) with those of subjects who recovered after an ankle sprain (LAS copers) and healthy controls during running and more challenging tasks. This study further aims to explore the impact of foot muscle properties and fatigue on the same biomechanical outcomes. Therefore, the investigators will recruit 72 participants (24 per group) aged from 18 to 44 years. Each of them will come only once to the CMAL laboratory (UZ Leuven, Pellenberg).
The former purpose of this study to investigate the effect of transverse abdominis, lumbar multifidus, vastus lateralis, lateral gastrocnemius, anterior talofibular ligament of morphology on explosive power and balance performance in cronic ankle instability with volleyball players. The latter purpose of this study to determine morphological characteristics volleyball players with and without cronic ankle insatbility of trunk muscle morphology, field tests and the muscle morphology features between the body affected and unaffected sides whose those with chronic ankle instability.This study was designed as a cross-sectional. Twelve volleyball players with chronic ankle instability who meet the criteria determined by the ankle consortium will be included in study group. Twelve asymptomatic volleyball players who have been training at least three days a week for at least one year will be include in the control group. They will consist of 24 volleyball players between 14-35 years of age.Morphological characteristics of anterior talofibular ligament, transverse abdominis, lumbar multifidus, vastus lateralis, lateral gastrocnemius will be evaluated via ultrasound, explosive power with squat jump, counter movement jump and balance performance by Y-Balance Test. Trunk muscle morphology, core stabilization, explosive power, balance performance will have been compered in volleyball players with and without chronic ankle instability. The effects of morphological features on explosive power and balance performance will have been determined. It is anticipated that by determining the parameters that can be affected by instability with volleyball players, it will guide the professionals working in the field, countribute to treatment and preventive treatment programs.
This project consists of a randomized controlled study design. Study candidates will include all patients 18 years or older, who were evaluated at UCSD and found to have an acute ankle syndesmosis injury requiring surgery. Patients who consent to study participation will be randomized to receive one of two standard of care procedures - either a suture button or Fibulink implant. Outcome measures, including the Olerud-Molander and American Orthopaedic Foot and Ankle Society scores, pain, range of motion, time to return to work, and radiographic evaluation will be collected for each participant. Given the potential degenerative changes and poor radiographic and clinical outcomes with inadequate repair of the syndesmosis, it is imperative to evaluate existing and emerging methods of fixation for patients with acute ankle fractures with syndesmosis injuries.
GJL is a risk factor for postoperative recurrent instability following an MBR for CLAI. BPR with suture tape augmentation and anatomic reconstruction may provide more strength and stability. However, BPR with suture tape augmentation may lead to rejection of the suture tape, while anatomic reconstruction may be associated with more trauma. In addition, the outcomes between the BPR with suture tape augmentation and anatomic reconstruction were unknown.
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.
The goal of this observational prospective cohort study is to determine key clinical predictors for chronic ankle instability and return to sports in patients who suffered an acute ankle sprain. The researchers will evaluate clinical outcome measures and patient reported outcome measures on 3 test moments and at 12 months of follow-up.
Ankle fractures are a common injury with potentially significant morbidity. Syndesmosis injury occurs in 10% to 13% of ankle fractures and poses a greater risk to long-term outcomes for patients. The gold standard for syndesmosis fixation has traditionally been screw fixation. However, issues with screw fixation include screw breakage, screw loosening, reoperation, and malreduction. Due to growing concerns with static screw fixation, implants based on the flexible suture button design, such as the TightRope system, gained traction. The Fibulink Syndesmosis Repair System, a relatively new design that became clinically available in 2017, has showed promising results. To our knowledge, there is no study that directly compares outcomes with the Fibulink implant to suture button implants.
Study population: the investigator set them sample size to 30 patients. Primary endpoint (concerning both study questions): is the applied torque measurement in Newton meters (maximum up to 7.5 Nm) up to the pain tolerance limit. For the chronic injuries, a minimum of 5 Nm should be achieved. If this is not possible due to pain, an intra-articular infiltration into the upper ankle joint with 5ml Ropivacaine 2% is performed under sterile conditions. In addition, fibula translation while exercising the maximum tolerated External Torque CT (maximum up to 7.5 Nm). Secondary endpoint (1st study question): the comparison to stress fluoroscopy without anesthesia and under anesthesia. Secondary endpoint (2nd study question): the comparison of patients with and without symptoms. Secondary endpoint in patients who received intra-articular infiltration is the increase in tolerated Newton meters.
The primary objective of this study is to evaluate the feasibility of implementing BFR in the rehabilitation treatment of isolated ankle sprains as well as to evaluate the clinical benefits of BFR when compared to standard treatment. This study will evaluate the efficacy of using BFR therapy for the treatment of acute grade I and II ankle sprains. The investigators will evaluate clinical outcomes of range of motion (ROM) and strength testing of ankle dorsiflexion, plantarflexion, inversion, and eversion. This will be a small, randomized control trial study. The investigators will enroll a total of 40 participants, 20 participants will undergo standard physical therapy for isolated lateral ankle sprains and 20 participants will undergo BFR therapy for an isolated lateral ankle sprain. Patients will be randomized into control and experimental group via block randomization.
In the general population, ankle sprains are one of the most common injuries, accounting for approximately 20% of all sports injuries and the most frequent reason for trauma consultation (4 to 7% of admissions to emergency departments in France). The most frequent complication after an episode of ankle sprain is the development of chronic ankle instability (5 to 40% of the patients). Chronic ankle instability is defined by a history of at least one significant ankle sprain with subsequent perception of an abnormal ankle by the patient, associated with various symptoms including: recurrent sprains, repeated episodes of ankle "slippage", pain, episodes of swelling, difficulty and apprehension when walking on uneven surfaces with a decrease in the functional capacity of the ankle or restriction of activity. In the military population, ankle sprains account for 18.60% of on-duty injuries, and epidemiologic studies report an incidence of 45.14 to 58.40 sprains per 1,000 person-years. A 2019 study in a population of French military paratroopers found a prevalence of chronic ankle instability of 43.1% after an ankle sprain. Chronic ankle instability leads to a loss of operational skills in French soldiers, since it results in a score of 4 for the letter "I" (pelvic girdle and lower limbs) in the SIGYCOP military medical profile. The treatment of chronic ankle instability after failure of rehabilitation consists in ligamentoplasty, conservative or not, in order to restore an external ligament plane and stabilize the ankle. For open techniques, the median time to return to sport after ligamentoplasty is 4.7 months. In the series by Lee et al, which studied more specifically the return to sport in high-level athletes, 83.3% of athletes had returned to competitive sport at 4 months and 100% at 8 months. Management of chronic ankle instability by ligamentoplasty may allow the soldier to regain his operational ability (SIGYCOP score I=2).
