Filter by:This open-label field trial evaluates the effects of treatment with a multi-pathway dietary supplement (Stem Cell 100+) that has been commercially available for several years. The objective of the intervention trial is to determine if normal subjects over 35 years of age experience any observable health benefits from the dietary supplement as to their blood pressure, pulse rate, blood cholesterol, lung capacity, stress levels, or self reported changes in markers of overall health and life expectancy.
Rationale: Lateral ankle ligament injuries may be a result of ankle sprains. In 10-30% of patients with lateral ankle ligament injuries, chronic lateral ankle instability may be present. If conservative treatment fails, instability is treated surgically. Anatomic repair (also known as the Bröstrom procedure) is the current golden standard for surgical treatment of chronic ankle instability. The Bröstrom started out as an open technique and is now also performed arthroscopically. Both approaches are considered standard care and provide good results. Which approach is best, has not yet been researched. In this study it is hypothesized arthroscopic repair provides better functional outcome compared to open repair during short term follow-up. Objective: The main objective of this study is to compare the functional outcome after arthroscopic and open anatomic repair in patients with chronic lateral ankle instability, and secondly to assess ankle stability and ankle Range of Motion (ROM) after arthroscopic and open ligament repair. Study design: A Non-Blinded Prospective Randomized Controlled Trial Study population: All patients willing to participate, from an age of 18 years old, with persisting ankle instability for at least 6 months, eligible for anatomic repair. Intervention: Both groups of patients are surgically treated with anatomic repair of the anterior talofibular ligament (ATFL). One group is treated arthroscopically and the other by the open approach. Main study parameters/endpoints: The primary outcome measure is functional outcome 6 months after surgery measured using the Foot and Ankle Outcome Score. The main study parameter is a difference of ≥10 2 points per FAOS subscale between both treatment groups (Minimal Important Change = 10 points; 2 per subscale).
Case control study to evaluate different factors (e.g muscle strength, psychological factors) that are associated with full recovery and functional status 6 months after surgical repair of shoulder instability.
Chronic ankle instability is a common problem that may follow an ankle sprain. Until a patient has developed chronic ankle instability they are ineligible for surgical treatment although early surgical treatment yields better results compared to surgical treatment of subjects that have experienced recurrent ankle sprains. However, treating all patients with an ankle sprain surgically is not an option due to the high amount of unnecessary invasive interventions. The objective of this study is to identify which patients will develop chronic ankle instability and to develop a model to predict which patients should receive early surgical treatment. In this prospective observational cohort all patients (older than 18 years) that report at the emergency department of the participating hospitals after a lateral ankle sprain, of whom an x-ray is made after positive Ottawa Ankle Rules and on which there is no visible fracture or other pathology. The main study parameter is a significant difference in patient characteristics, foot and ankle configuration and joint pathology between patients who develop chronic ankle instability and patients who do not experience recurrent ankle sprains and restriction during daily live after an initial sprain.
Case-control study to evaluate gait parameters during different conditions between patients who suffer from chronic ankle instability and healthy individuals.
Background: There is no evidence that shoulder stabilization effectively corrects the glenohumeral translation in unstable shoulders, explaining residual apprehension in certain patients. The purpose of this study was to analyze the effect of surgical stabilization on glenohumeral translation. Methods: Anteroposterior and superoinferior translations were assessed in patients, before and after shoulder stabilization, through a dedicated patient-specific measurement technique based on optical motion capture and computed tomography.
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.
Prospective, monocenter post market clinical follow-up of a primary knee replacement bearing the CE-mark. 200 subjects will be recruited and followed up for up to ten years or until revision of the primary knee endoprosthesis, whichever occurs first. Documentation of clinical and radiological parameters within the clinical routine pre-operative and post-operative at 3 and 12 months and 2, 5 and 10 years to evaluate time to revision, pain situation, knee functionality, mobility and stability.
This prospective randomized control trial (PRCT) aims to compare the outcome of three treatments for acute distal radioulnar joint (DRUJ) injury with instability with or without concomitant distal radius fractures: serial splinting/casting with the hand and wrist in the most stable position for DRUJ reduction vs percutaneous DRUJ fixation with Kirschner wires vs open anatomic foveal repair of Triangular fibrocartilage complex (TFCC ) ligaments.
To date, use of arthroscopic procedure to perform Latarjet procedure is still technically demanding. The benefits of arthroscopic procedure need to be evaluated compared to the mini-invasive approach. The aim of this study was to assess postoperative pain during the first week, and the positioning of coracoid bone block at the anterior aspect of the glenoid. At minimum 2 years follow-up, the recurrence of shoulder instability and functional evaluation of patients according to the Western Ontario Score Index (WOSI) were assessed.
