Comparing nerve blocks for pain after knee replacement surgery
This trial tests if adding extra nerve blocks (sciatic, BiFeS, or IPACK) to the usual adductor canal block can reduce pain after total knee replacement. The goal is to find a better way to manage pain and improve recovery.
Erzincan, MerkezAges 18–75 - NCT07449442Recruiting

Bone density change after knee replacement with or without cement
This study looks at how bone density in the thigh bone changes after knee replacement surgery, comparing two ways of attaching the new joint (with cement or without). It may help people who have normal bone density or early bone thinning but not full osteoporosis.
Madison, WisconsinAges 55 years+ - NCT06182059Recruiting
