Active clinical trials for "Joint Instability"

The scientific justification is to fulfill post-market clinical requirements in order to support re-certification of the CE-Mark for this marketed product and to look into safety and efficacy.

Study Design: Evaluation of the psychometric properties of a translated, culturally adapted questionnaire. Objective: Translating, culturally adapting, and validating the Italian version of the Cumberland Ankle Instability Tool (CAIT-I), allowing its use with Italian-speaking population to monitor both state of health and functional limitation deriving from ankle instability problems, in order to evaluate the degree of severity, without using the comparison with the opposite limb. Summary of Background Data: Lateral ankle sprain is the most common injury during sports activity, often cause of disability and of numerous complications following repeated episodes, including chronic ankle instability (CAI), which affects 32% to 74% of the aforementioned cases. Growing attention is devoted to standardized outcome measures to improve interventions for injured population. A translated form of the Cumberland Ankle Instability Tool (CAIT), a simple and specific tool for diagnosing chronic lateral ankle instability with excellent psychometric characteristics of both reliability and validity, has never been validated within the Italian speaking population.

The aim of our study was to determine the joint mobility levels and its effects on performance in male basketball players and their sedentary peers aged 16-22 years. According to the studies on the effect of hypermobility on the performance; The young athletes who played tennis had lower equilibrium results than those without hypermobility. Although there is not any study that investigate its effects in basketball, there are studies for tennis and volleyball in literature.

Background : Segmental spinal instability after a laminectomy, and adjacent segment disease (ASD) at after an arthrodesis, are well-known concerns in spinal surgery, which may require re-interventions, usually by surgical arthrodesis, posing the problem of a new heavy intervention under general anesthesia, in often fragile patients. Trans-facet fixation (TFF) under local anesthesia and double fluoroscopic and CT guidance is a minimally invasive technique involving the placement of screws through the posterior facet joints, improving spinal stability. Purpose : The aim of our study is to evaluate the efficacy, in terms of pain reduction (VAS) and improvement of daily activities (ODI), of TFF under CT scan guidance in the context of low back pain and/or radiculalgia related to focal instability secondary to laminectomy or ASD. Methods : TFF were performed in 24 patients having a history of spinal surgery such as laminectomy and/or classic surgical arthrodesis and remaining symptomatic, at Nice University Hospital between 2017 and 2021 Pre- and postoperative pain and disability levels were measured using the visual analogue scale (VAS) and the Oswestry Disability Index (ODI), collected prospectively at systematic 6-month and 1-year follow-up visits. Long term evolution were assessed by phone consultation.

This study will look to examine the overall performance of a custom fit knee or ankle brace as a means of providing ankle or knee joint support in subjects that have determined the need for bracing based upon chronic joint instability and/or joint swelling and pain following daily activity.

Patients who received a total knee endoprosthesis BPK-S Integration between 2011 and 2013 will be invited to participate in this PMCF study provided sufficient source data documentation is available regarding preoperative, intraoperative and early postoperative follow-up assessments. Only patients providing written informed consent prior to any study data collection can take part in the study. Preoperative, intraoperative and early postoperative data (3 months, 1 year and 2 years after implantation) will be collected retrospectively. Additional long-term follow-up of one visit (year 7 after implantation) will be documented prospectively. Only parameters assessed in clinical standard care for follow-up (implant control) visits will be collected for this PMCF study. Radiological assessment of the implanted prosthesis will only be conducted if medically indicated according to the investigator. No additional study related assessment will be performed. Only anonymized data will be used in this observational study to protect patient privacy. No personally identifiable information will be collected.

Brittle Cornea Syndrome and Ehlers-Danlos Syndrome (EDS) type VI are rare collagen-connective tissue disorders that predispose affected individuals to the development of perforated corneas from the mildest of eye trauma or even spontaneously. Clinical studies evaluating riboflavin-corneal crosslinking have found that it dramatically increases corneal rigidity. Given the success and safety of riboflavin crosslinking, the investigators believe that it can increase the corneal stability in patients affected these disseases, preventing perforation. It is furthermore possible, that riboflavin crosslinking will allow corneal transplants to successfully be performed on blind eyes that have already perforated and opacified. The purpose of the study is to determine whether corneal crosslinking can be safely performed on individuals with Brittle Cornea Syndrome or Ehlers-Danlos Syndrome type VI.

Prospective, multicenter, observational, comparative clinical trial on the equivalence of two different OrthoPilot® navigation system generations applied for computer-assisted total knee arthroplasty

This study will collect information on the different ways that people walk, that is, their gait, when they use ankle braces. Patients will visit NIH on at least three and as many as nine separate occasions. A physical therapist will perform a physical examination to determine how patients move, how strong they are and what their comfortable walking speed is. Then patients will sit on a chair while a camera apparatus takes special pictures of their legs, a procedure lasting up to 2 hours. Patients will be asked to return to learn how to walk with the custom Passive Dynamic Ankle-Foot Orthosis (PD-AFO)-a unique ankle brace designed to improve walking ability by providing natural support to the lower limb. Patients 4 and older who are in good health and able to walk repeatedly a distance of 15 meters (approximately 49 feet) independently and unsupervised may be eligible for this study. With this training, patients may return several times to learn how to walk with the brace, but for their protection, they will not be allowed to take it or use it outside the research team's supervision. The researchers will examine the leg to ensure that the brace fits and will ask questions about it. Each training visit will require up to 1.5 hours. When patients have learned to walk with the brace, they will be asked to visit again and walk while scientific pictures are taken of their legs. During the walking test, patients will wear T-shirts and shorts. Patients' arms and legs will be wrapped with a soft, rubber-like material, to allow small plastic reflective balls to be attached. Firm material known as a shell can be attached to the rubber sleeves, with Velcro or a self-sticking bandage. The small balls may also be attached to the skin, with an adhesive. Also, there may be a test of the muscles, through the use of electromyography, or EMG. The test involves attachment of small metal electrodes to the surface of the skin, again with an adhesive. There should not be discomfort with that test. As patients walk several times, scientific cameras will record the positions of the reflective balls. Pictures do not involve patients' faces or other parts of the body. Afterward, a unique chair system called a Biodex will measure the leg muscle strength. Patients will be asked to sit on the chair and place their leg in a foot in an apparatus, a special structure that measures strength. They will repeatedly push against the apparatus, doing so for 3 seconds. Each time patients push, the researchers will touch a small magnetic device to the skin, which will cause the muscles to push harder. Although this procedure should not cause any discomfort, it may feel unusual. If they wish, patients can ask to stop the test at any time. Few risks are involved in participating in this series of activities. There is a slight chance of mild skin irritation from the adhesives used on the skin or from the soft, rubber-like material. But the material is worn for only a brief period, and skin reactions are rare. Also, that material may feel tight, but if it causes discomfort or prevents moving, patients can ask a researcher to adjust it. There is a slight chance of skin irritation from use of the PD-AFO, but adjustment can be made to make patients comfortable. Patients may experience some muscle soreness caused by participating in the muscle strength tests. However, they will be safely monitored by a physical therapist when they try on the brace to adjust to its feel and fit, as well as during testing of gait. This study will not have a direct benefit for participants. However, participants will be paid for their time, with minimum compensation of $50.

Abstract Introduction: The high prevalence of sprains in the population has provided a substantial number of patients with lateral instability of the ankle. The continuity of this condition can lead to the progressive loosening of the medial containment structures, generating a multidirectional rotational instability. The deltoid approach through the imbrication of its components has been proposed as a solution for these patients. The arthroscopic technique has been described as an alternative. Methods: This is a retrospective study with patients diagnosed with multidirectional instability and submitted to an ankle arthroscopy with medial repair (arthroscopic tensioning) and lateral (arthroscopic Brostrom) between January 2018 and January 2020. All patients will fill an epidemiological questionnaire and will be evaluated for pain and function according to the Visual Analogue Scale (VAS) and the American Orthopaedic Foot and Ankle Society Score (AOFAS) at 12 months (6-24 months) average of follow-up. Discussion: The combined medial and lateral arthroscopic repair may be an effective and safe alternative in the treatment of multidirectional instability. The inclusion of the deltoid complex and the low invasiveness of this technique can improve the clinical outcomes of these patients. Additional studies, with a prospective and comparative methodology are required to sustain this proposal. Design: Level IV. Retrospective case series.
