Conclusions

In summary, the type of anesthesia technique does not alter short term serious adverse events, readmissions, and failure to rescue in patients undergoing outpatient total knee replacement. In contrast, patients who received general anesthesia reported a greater rate of minor and any adverse events compared to patients who received spinal anesthesia. Specifically, the rate of blood transfusions was reduced in patients who received spinal anesthesia compared to general anesthesia in the early postoperative period. Clinicians should recognize the benefits of spinal anesthesia in patients undergoing outpatient knee replacements and tailor the anesthetic plan to maximize clinical benefits.
