-
Good Boost+ for adults awaiting knee replacement
This feasibility trial tests whether a community-based prehabilitation program called Good Boost+ can be run with people waiting for a knee replacement and whether it could work in larger future studies.
-
Multimodal prehabilitation before elective hip or knee replacement for frail older adults
This program will test whether a tailored multimodal prehabilitation package can help frail adults aged 70 and older who are waiting at least two months for elective hip or knee replacement do better around the time of surgery.
-
Faster rehabilitation after total knee replacement
This trial will test whether a faster rehabilitation program helps people aged 50–80 recover better and have better quality of life after their first unilateral total knee replacement.
-
Intrathecal morphine and urinary retention after revision knee replacement
This study will see if adding a small dose of spinal (intrathecal) morphine for adults having revision knee replacement lowers early pain but raises the chance of needing a urinary catheter.
-
Micronized creatine to help muscle strength and performance after knee replacement in older adults
This trial will test whether taking daily creatine for 12 weeks after knee replacement helps people 65 and older keep muscle, regain strength, and recover function.
