Effect of Spinal versus General Anesthesia in Study Comparing Three Methods of Using Local Anesthetics to Achieve Post–knee Arthroplasty Pain

The authors of a recently published study¹  comparing three local anesthetic methods of reducing post–knee arthroplasty pain recommended spinal anesthesia, but 23% of patients apparently still received general anesthesia. Would the authors be kind enough to share the postoperative pain score data for these two patient groups (i.e., spinal vs. general anesthesia)?

The author declares no competing interests.
