Background: The relative analgesic requirements for tricompartmental (TKA) and unicompartmental (UKA) knee arthroplasty and their effects on discharge readiness remain unexamined when continuous adductor canal and femoral nerve blocks are used for analgesia in the immediate postoperative period. Methods: Data were collected from 2 previously-published clinical trials involving subjects undergoing TKA (n=79) or UKA (n=30) randomized to either an adductor canal or femoral perineural catheter and ropivacaine 0.2% infusion for 2 (UKA) or 3 (TKA) days. Originally, we compared each catheter location (adductor vs. femoral) while holding surgical procedure constant (comparing solely TKAs and solely UKAs). We now compare type of surgical procedure (TKA vs UKA) while holding catheter location (adductor vs. femoral) constant. The primary outcome was the time to attain 4 discharge criteria including pain, opioid requirements, and ambulation/mobilization. Results: For adductor canal catheters, UKA patients reached all 4 discharge criteria in 35 [24—43] hours which was significantly faster than those given TKA who took 55 [43—63] hours (difference: 18h; 95%CI 9 to 28 h; P |
