This trial compares two types of knee replacement implants in people aged 75 and older: a standard metal-backed component and a cheaper all-polyethylene (plastic) one. The goal is to see if the all-polyethylene implant performs as well in terms of pain relief, movement, and how l…

This study tests whether taking a 7-day course of oral antibiotics after hip or knee replacement surgery can prevent joint infections in patients at higher risk due to conditions like obesity, diabetes, or autoimmune disease. About 4,600 participants will receive one of three ant…

This early-phase study tests a new type of CAR-T cell therapy in 9 people with autoimmune diseases that have not responded well to standard treatments. The therapy uses specially engineered immune cells to target and attack faulty immune cells. The main goal is to check safety an…

This study follows 200 people who receive a cementless knee replacement (GMK Sphere) to see how long the implant lasts and how well it works. Participants have severe knee damage from arthritis or other conditions. The goal is to monitor safety and performance in real-world use, …

This Mayo Clinic study tests a new 3D MRI sequence called oZTEo, enhanced with deep learning, to detect bone erosions in the hands of people with inflammatory arthritis. The goal is to see if this advanced scan finds erosions better than standard MRI or X-rays. The study will enr…

This study aims to create a tool that predicts which patients with inflammatory rheumatic diseases (like rheumatoid arthritis, vasculitis, or polymyalgia rheumatica) will develop serious side effects from long-term steroid use. Researchers will collect routine medical data—such a…

This registry enrolls up to 1,000 women aged 12–55 with rheumatic or autoimmune diseases who are pregnant or planning pregnancy. Researchers will collect data from medical records and patient surveys to study pregnancy outcomes, disease activity, and medication use. No experiment…

This study is tracking 120 people who received a HYPE SCS hip stem during total hip replacement. Researchers will monitor how long the implant lasts, how satisfied patients are, and any complications over 5 years. The goal is to confirm the device is safe and works as intended in…

This study looks at whether helping people with inflammatory arthritis address social needs—like food, housing, or transportation—can reduce missed doctor visits. About 100 adults with conditions like rheumatoid arthritis or lupus who have missed appointments in the past year wil…

This study looks at immune cells from people with autoimmune diseases (like lupus), people with infections, and healthy volunteers. Researchers want to understand how these cells differ and what makes them attack the body in autoimmune conditions. The study involves blood and bon…
