Comparison of spinal anesthesia and general anesthesia in total hip and total knee arthroplasty: a meta-analysis and systematic review

In total hip replacement and total knee replacement, spinal anesthesia may be more beneficial to patients. Therefore, if contraindications to spinal anesthesia are excluded, spinal anesthesia should be used as much as possible, especially for some special populations, such as patients with poor basic conditions, based on our results, who should be more inclined to spinal anesthesia.
