Avascular necrosis of femoral head, primary, 1

This study is testing a new hip replacement system called the HIT Reverse Hip Replacement System. It is for people aged 50 to 75 who need a total hip replacement due to arthritis, joint damage, or other conditions. The goal is to see if the new system is as safe and effective as …

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 study is checking how well the Z1 Femoral Hip System works and how safe it is for people who need hip replacement surgery. About 150 adults with hip problems like arthritis or fractures will be followed for 2 years. The main goal is to see how many implants are still in plac…

This study is testing a new knee replacement system called Persona Revision for people who need a second knee replacement surgery. The goal is to see if it improves knee function, reduces pain, and is safe. About 380 adults will be followed for two years after surgery.

This study tests a new way to treat early-stage avascular necrosis (bone death) of the hip. Doctors take a patient's own bone marrow stem cells, grow them on a special bone scaffold in the lab, and then implant this 'tissue-engineered bone' into the damaged area. The goal is to s…

This study is testing a new hip replacement system called Emphasys Hip Solutions in 30 people with hip osteoarthritis. Researchers will use special X-ray imaging to see how well the implant stays in place over two years. The goal is to make sure the implant is stable and works we…

This study is tracking 550 adults aged 18–75 who receive the Medacta SMS femoral stem during total hip replacement. Researchers will monitor how long the implant lasts, how well the hip functions, patient satisfaction, and quality of life. The goal is to confirm the device's safe…

This study is looking for substances in the blood that can help doctors diagnose osteonecrosis of the femoral head (a condition where the hip bone dies) much earlier. Currently, many cases are missed or misdiagnosed. Researchers will collect blood from 300 people with suspected h…

This study looks at how well a non-invasive navigation system helps surgeons place the hip cup during total hip replacement. About 118 people with hip conditions like arthritis or hip dysplasia will take part. The goal is to see if the actual cup position matches the planned posi…

This study follows 2500 people who have had hip replacement surgery with Corin implants. Researchers will check how long the implants last and how well they work over 10, 15, and 20 years. The goal is to gather safety and performance data, not to test a new treatment.

This study compares two antiseptic washes used during hip replacement surgery to see which one helps wounds heal better. About 420 adults with hip osteoarthritis or avascular necrosis will be randomly assigned to receive either povidone-iodine or chlorhexidine wash after their ne…
