General versus spinal anaesthesia for outpatient knee and hip replacement
Part of Pain clinical trials.
This trial compares the effects of two types of anaesthesia—one that puts you fully asleep (general anaesthesia) versus one that numbs the lower half of your body while you stay awake (spinal anaesthesia)—for people having knee or hip replacement surgery. The goal is to see which approach leads to better recovery and fewer problems, so you can go home the same day.
Summary written for real people, not researchers, by Clin2.

This study compares two types of anesthesia (general and spinal) for people having a total hip or knee replacement. The goal is to see which approach is better for recovery and overall outcomes.
This study compares two types of anaesthesia (spinal vs. general) for hip and knee replacement surgery. It aims to see which one provides better pain control and recovery. If you are having this surgery, you may be able to participate.
This trial compares total intravenous anesthesia (TIVA) with spinal anesthesia for people having a first-time total knee replacement who are expected to go home the same day. The goal is to see which method works better for recovery and comfort.
This study compares two types of spinal anesthesia (numbing medicine injected near the spine) to see which one provides better pain relief and a shorter recovery for hip replacement surgery. If you qualify, you would receive one of the two medications during your surgery and help doctors learn which is more effective for getting you home the same day.
This study compares two ways of managing pain during hip replacement surgery: one that reduces the use of strong painkillers (opioids) using a special monitor, and one that avoids them altogether. The goal is to see which approach controls pain better with fewer side effects.
This Phase 2 study compares two ways of reducing nerve pain after knee replacement surgery (total knee arthroplasty). It looks at whether steroid-enhanced pain medicine works better than a different numbing injection to improve recovery and comfort.
