Over 500,000 total knee arthroplasties (TKAs) are performed annually in the US, yet postoperative pain management varies widely. In patients managed with epidural analgesia, the epidural catheter is generally removed on the second postoperative day. We compared in-hospital outcomes associated with removing the epidural catheter on postoperative day 1 (POD1-group) vs on postoperative day 2 (POD2-group) among patients undergoing TKA. We identified 89 patients who had TKA performed by a single surgeon from January through July 2007, and who were managed with epidural analgesia. This study took advantage of a change of policy from removing the epidural on the second postoperative day prior to March 2007 (n = 34) to removing the epidural on the first postoperative day thereafter (n = 55). Data were obtained by medical record review and analyzed with bivariate and multivariate techniques. Outcomes included knee range of motion (ROM), pain (0-10 scale), distance walked, narcotic usage, and...

Background and Objectives: Regional analgesic techniques allow better postoperative rehabilitation and shorter hospital stay after major knee surgery. The authors tested the hypothesis that similar results could be obtained after total-hip arthroplasty. Methods: Forty-five patients scheduled for THA under general anesthesia were randomly divided into 3 groups. Postoperative analgesia was provided during the first 48 hours, with intravenous patient-controlled analgesia (IV PCA) induced by morphine (dose, 1.5 mg; lockout interval, 8 min) in group IV, continuous femoral nerve sheath block in group FNB, and continuous epidural analgesia in group EPI. The day after surgery, the 3 groups started identical physical therapy regimens. Pain scores at rest and on movement, supplemental analgesia, side effects, daily degree of maximal hip flexion and abduction, day of first walk, and duration of hospital stay were recorded. Results: Population data, quality of pain relief, postoperative hip rehabilitation, and duration of hospital stay were comparable in the 3 groups. When compared with the two other techniques, continuous FNB was associated with a lower incidence of side effects (no nausea/vomiting, urinary retention, arterial hypotension, or catheter problem during the first 48 hours in 20%, 60%, and 13% of patients in groups IV, FNB, and EPI, respectively). Conclusions: This study suggests that IV PCA with morphine, continuous FNB, and continuous epidural analgesia provide similar pain relief and allow comparable hip rehabilitation and duration of hospital stay after total-hip arthroplasty (THA). As continuous FNB is associated with less side effects, it appears to offer the best option of the three.

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 signi cantly faster than those given TKA who took 55 [43-63] hours (difference: 18h; 95%CI 9 to 28 h; P<0.001). The results were similar for femoral catheters: UKA patients reach all four discharge criteria in 40 [27-58] hours which was signi cantly faster than those given TKA who took 61 [49-69] hours (difference: 20; 95%CI 4 to 30 h; P=0.009). For both catheter locations, pain scores, opioid requirements, and mobilization endpoints were better with UKA than TKA. Conclusion : UKA induces less pain and requires less opioid than TKA, regardless of perineural catheter location. Consequently, patients who have UKA are ready for discharge sooner.

Background and objectives: Total knee arthroplasty and total hip arthroplasty are associated with chronic pain development. Of the studies focusing on perioperative factors for chronic pain, few have focused on the differences that might arise from the anesthesia type performed during surgery. Methods: This was a prospective observational study performed between July 2014 and March 2015 with patients undergoing unilateral elective total knee arthroplasty (TKA) or total hip arthroplasty (THA) for osteoarthritis. Data collection and pain evaluation questionnaires were performed in three different moments: preoperatively, 24 hours postoperatively and at 6 months after surgery. To characterize pain, Brief Pain Inventory (BPI) was used and SF-12v2 Health survey was used to further evaluate the sample's health status. Results: Forty and three patients were enrolled: 25.6% men and 74.4% women, 51,2% for total knee arthroplasty and48.8% for total hip arthroplasty, with a mean age of 68 years. Surgeries were performed in 25.6% of patients under general anesthesia, 55.8% under neuraxial anesthesia and 18.6% under combined anesthesia. Postoperatively, neuraxial anesthesia had a better pain control. Comparing pain evolution between anesthesia groups, neuraxial anesthesia was associated with a decrease in ''worst'', ''medium'' and ''now'' pain at six months. Combined anesthesia was associated with a decrease of ''medium'' pain scores at six months. Of the three groups, only those in neuraxial group showed a decrease in level of pain interference in ''walking ability''. TKA, ''worst'' pain preoperatively and general were predictors of pain development at six months.

This randomised controlled trial compared three analgesia regimens following primary unilateral total knee joint replacement: continuous femoral nerve block (CFNB), intrathecal morphine (ITM), and both. The primary outcome was pain ratings over the first 24 hours. Secondary outcomes included morphine consumption, nausea, pruritus and sedation ratings, oxygen saturation (SpO2) ratings, and ability to mobilise postoperatively. All patients received a spinal anaesthetic and a postoperative patient-controlled morphine pump. Patients were randomised to receive CFNB, ITM, or both. In patients with no CFNB, the use of ITM was blinded. Eighty-one patients were randomised and there were no withdrawals. At 24 hours, the ITM-only group had higher pain ratings than either of the other groups (P=0.04 versus CFNB, P=0.01 versus combination). In the 18 to 24 hour period, the ITM group used more morphine than either of the other groups. There were no statistically significant differences in pain ra...
Background There have been few studies describing wound infiltration with additional intraarticular administration of mul-timodal analgesia for total knee arthroplasty (TKA). In this study, we assessed the efficacy of wound infiltration combined with intraarticular regional analgesia with epidural infusion on analgesic requirements and postoperative pain after TKA. Methods 40 consecutive patients undergoing elective, primary TKA were randomized into 2 groups to receive either (1) intraop-erative wound infiltration with 150 mL ropivacaine (2 mg/mL), 1 mL ketorolac (30 mg/mL), and 0.5 mL epinephrine (1 mg/mL) (total volume 152 mL) combined with intraarticular infusion (4 mL/h) of 190 mL ropivacaine (2 mg/mL) plus 2 mL ketorolac (30 mg/mL) (group A), or (2) epidural infusion (4 mL/h) of 192 mL ropivacaine (2 mg/mL) combined with 6 intravenous administrations of 0.5 mL ketorolac (30 mg/mL) for 48 h postoperatively (group E). For rescue analgesia, intravenous patient-controlled-analgesia (PCA) morphine was used. Morphine consumption, intensity of knee pain (0–100 mm visual analog scale), and side effects were recorded. Length of stay and corrected length of stay were also recorded (the day-patients fulfilled discharge criteria). Results The median cumulated morphine consumption, pain scores at rest, and pain scores during mobilization were reduced in group A compared to group E. Corrected length of stay was reduced by 25% in group A compared to group E. Interpretation Peri-and intraarticular analgesia with multi-modal drugs provided superior pain relief and reduced morphine consumption compared with continuous epidural infusion with ropivacaine combined with intravenous ketorolac after TKA.

Introduction: Although controversial, preemptive analgesia has shown some promise in preventing altered pain perception and reducing pain amplification after surgery. Hence, it has the potential to be more effective than a similar analgesic regimen started after surgery with an appropriate combination of patient category and analgesic modality. Hence, the present study was undertaken to evaluate the effect of preventive epidural analgesia in reducing pain severity and duration after bilateral single-stage knee arthroplasty. Methods: Fifty patients, 18-70 years, with American Society of Anesthesiologists physical status class I & II posted for bilateral single-stage knee replacement under regional anesthesia were randomly allocated into preventive versus postoperative epidural analgesia group to compare severity of post-operative pain, analgesic consumption, day of mobilization, C-reactive protein (CRP) levels, and hospital stay. Results: The pain score after surgery [2.0 (1.5, 2.0); 3.0 (1.5, 3.0), p = 0.005] and day of mobilization [(2. 92 ± 0. 28; 3. 31 ± 0. 48; p value 0.02)] were significantly lesser in the preventive epidural group. However, there was no difference in the hospital stay (9.92 ± 3.71 and 9.00 ± 2.12, p = 0.95) and analgesic consumption (65.38 ± 37.55 and 73.08 ± 43.85, p = 0.30). The preventive group had a larger drop in CRP and experienced a lesser number of days with pain after surgery as compared to the controls [(64.29 ± 21.29); (142.37 ± 80.04), p = 0.0001]. Six patients in the preemptive group (24%) and 13 of the control group (24 vs. 56.5%; p = 0.02) had chronic postsurgical pain. Conclusions: Preventive epidural analgesia reduces the severity and number of chronic pain days after bilateral single-stage knee replacement.
