Joint Instability

This clinical trial is designed to evaluate whether a stepwise injection-based treatment approach can reduce pain and improve function in adults with joint hypermobility, connective tissue laxity, and joint instability. Joint hypermobility occurs when joints move beyond their normal range, often because of looser connective tissue. For some patients, this can contribute to chronic pain, recurrent instability, reduced function, and disability. This study focuses on adults with hypermobile Ehlers-Danlos syndrome (hEDS), hypermobility spectrum disorder (HSD), or joint instability after injury who have already completed physical therapy without adequate relief. The main question this study aims to answer is whether the first treatment step, dextrose prolotherapy, can reduce pain by 40% or more two weeks after the second injection. Participants will receive treatment in a step-by-step sequence, based on their response: Step 1: Dextrose prolotherapy A dextrose-based injection used to stimulate a healing response in ligament, tendon, or joint-supporting tissue. Step 2: Platelet-rich plasma (PRP) An injection prepared from the participant's own blood, designed to support tissue repair and recovery. Step 3: Doxycycline injections A low-dose injectable treatment used in this study to help protect joint-supporting tissue. It is not being used to treat infection. Alternative option: Hyaluronic acid injections An injection into the joint that may be offered if the earlier treatment steps do not provide enough improvement. Each treatment step begins with two injections, given approximately two weeks apart. If a participant improves by 40% or more, they may continue with that treatment pathway. If they do not improve enough, they may be offered the next step in the study. Participants will be followed for up to 12 months, with study visits used to monitor pain, function, treatment response, and safety.

This is a multicenter, prospective, observational, post-market clinical follow-up (PMCF) study designed to evaluate the safety and clinical performance of the Tipmed™ Revision Hip Prosthesis System in adult participants undergoing revision hip arthroplasty. The study aims to gather real-world clinical evidence on the 24-month post-operative safety profile, potential complications, and functional outcomes of the device during routine clinical practice.

The goal of this randomized controlled clinical trial is to learn if adding neurocognitive loading to standard shoulder rehabilitation improves physical and psychological recovery in adults who have undergone arthroscopic anterior shoulder stabilization surgery (such as Bankart repair, Latarjet, or remplissage procedures). The main questions it aims to answer are: Does adding neurocognitive loading exercises improve shoulder proprioception, muscle strength, and functional performance compared to standard therapy alone? Does this integrated training approach reduce the kinesiophobia? Does it lead to better overall clinical outcomes and improve psychological readiness to return to sports? Researchers will compare a group receiving standard shoulder exercises combined with dual-task neurocognitive loading (using light-based reaction systems and cognitive tasks) to a control group receiving standard shoulder rehabilitation alone. Participants will:Undergo supervised physical therapy sessions starting 10 days after surgery up to the 16th postoperative week (twice a week for the first 12 weeks, and once a week for weeks 13-16) alongside an assigned home exercise program. Complete neurocognitive loading tasks (if assigned to the intervention group) that challenge attention, quick decision-making, and visual reactions while executing physical movements. Attend detailed clinical evaluation sessions lasting about 60 minutes before the treatment starts, and at 6, 12, and 24 weeks after surgery. These assessments include neurocognitive, functional and clinical tests, and questionnaires.
