Day of surgery discharge after unicompartmental knee arthroplasty: an effective perioperative pathway.

Abstract

Day of surgery (DOS) discharge after unicompartmental knee arthroplasty (UKA) allows for safe, efficient care of the appropriately selected patient. Refinement of our perioperative pathway over the last decade has allowed for successful DOS discharge of 160 consecutive patients. The cohort averaged 65 years and American Society of Anesthesiology class was 1-3 (mean, 1.8). Perioperative pain control included a preoperative single shot femoral nerve block. Mean recovery room time was 121 (SD = 37) minutes. No patient required overnight admission for uncontrolled pain or nausea. Significant improvements in Knee Society Clinical Rating System (KSCRS) scores and high patient satisfaction were observed. This study details critical components of our simple perioperative pathway that can be utilized to safely perform UKA with discharge on the DOS.
