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 tests whether using donated cartilage and bone cores can repair damaged knee cartilage in people aged 12 to 60. The damaged area is replaced with a preserved donor plug. The goal is to see if this improves knee function and reduces pain over time.

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 tests whether a long-acting form of the anesthetic bupivacaine, combined with regular bupivacaine, can control pain better than the standard drug ropivacaine after hip replacement. Sixty adults with hip fractures or necrosis will receive one of the two treatments via a…

This study tests if Schroth exercises, a special type of physical therapy, can improve shoulder muscle function in children aged 7-18 with a rounded upper back (thoracic hyperkyphosis). 56 participants will either do these exercises for 8 weeks or receive standard posture educati…

This study tests whether adding kinesiotaping (a special elastic tape) to exercise can improve posture, balance, pain, and quality of life in young adults aged 18-45 with a rounded upper back (thoracic hyperkyphosis). 48 participants will be split into three groups: exercise plus…
