Osteonecrosis

This study tests whether adding a patient's own concentrated bone marrow cells to a standard hip surgery (core decompression) can prevent the hip ball from collapsing and delay or avoid the need for a hip replacement. It includes 192 adults with early-stage osteonecrosis (before …

This trial tests whether injecting a person's own bone marrow into a hip fracture site helps the bone heal faster and more completely. Adults aged 18 to 55 with a specific type of hip fracture will receive either standard screw fixation alone or screw fixation plus a bone marrow …

This study is testing a shoulder replacement device in 300 people with shoulder arthritis, bone death, or rotator cuff tears. Participants receive the implant and are followed for 10 years to see how well it works and if it is safe. The goal is to improve pain and shoulder functi…

This study tests whether alendronate, a drug used for osteoporosis, can help adults with sickle cell disease who have bone damage (osteonecrosis). Thirty participants will take a weekly pill for 24 weeks. The main goals are to see if the treatment is feasible and safe, and to mea…

This study follows adults who have received a Tipmed shoulder replacement to see how well the implant works and if any problems arise over the first year. Participants have conditions like severe arthritis, rotator cuff damage, or a broken shoulder bone. Researchers track shoulde…

This study tests whether a new surgical irrigation solution called XPERIENCE can lower the risk of joint infection after hip or knee replacement better than the standard dilute Betadine wash. About 7,600 adults having primary hip or knee replacement will be randomly assigned to r…

This study looks at how well a short, bone-friendly stem works for total hip replacement when done through a front-of-hip incision. Researchers will follow 400 adults with hip arthritis for at least two years to check implant survival, complications, pain, and recovery. The goal …

This study tests whether 3D-printed models and custom surgical guides can help surgeons better plan and perform wrist bone cuts for Kienbock's disease (stages II and III). About 20 adults will receive the 3D-assisted surgery, and researchers will measure pain, wrist function, and…

This study is checking how long the Medacta Shoulder System lasts and how well it works in 200 people with shoulder issues like arthritis, fractures, or failed previous shoulder replacements. Participants will be followed over time to measure shoulder function, pain, and movement…

This study tests whether a special ultrasound with contrast dye can show blood flow to the hip joint in real time during surgery for hip dysplasia in infants. About 125 infants aged 4 to 24 months will receive the ultrasound during their hip reduction surgery. The goal is to see …

Avascular necrosis of the talus happens when the ankle bone loses its blood supply and collapses. Researchers are testing a custom-made implant shaped like the patient's own talus to replace the damaged bone. The study follows 50 adults for five years to see whether the implant r…

This study is tracking 20,000 people who have had or will have shoulder replacement surgery to see how well the implants work over at least 10 years. Researchers will measure pain, daily function, and strength using standard shoulder scores. The goal is to better understand the l…

This study looks at how children and young adults (ages 10 to 25) who had a joint replacement for reasons other than cancer are doing. Researchers will collect information from medical records and questionnaires about quality of life and joint function. The goal is to understand …

This study compares a standard and a new system for collecting bone marrow from the hip. Six adults aged 18–50 having minimally invasive hip repair will provide samples from both hips. The goal is to see which method collects more stem cells, cytokines, and growth factors. No new…

This study looks at whether brain scans can predict if someone will be satisfied after knee replacement surgery. Up to 1 in 5 patients still have pain or trouble moving after surgery, and doctors can't currently predict who. Researchers will scan the brains of 50 adults before an…

This study looks at how well a particular type of knee replacement works in 960 adults who had surgery between 2013 and 2024. Researchers will check knee function and X-ray results at least one year after surgery. The goal is to see how the prosthesis performs and compare it to o…
