Little information exists on national trends in the utilization of femoral nerve blocks (FNBs) in total knee arthroplasties (TKAs). We sought to describe the variations in anesthetic practice for FNB using the National Anesthesia Clinical Outcomes Registry. ⋯ There is considerable practice variation in the use of FNB for TKA, which is associated with various factors such as geographic location, time of day, and patient-specific comorbidities. Approximately one fourth of TKA cases include FNB. Overall, our study supports the clinical utility of FNB in TKA. As more data are compiled, it will be important to examine how national trends shift in the future.

Postoperative pain after total knee arthroplasty (TKA) poses a major challenge. It delays mobilization, increases opioid consumption and side effects, and lengthens hospitalization. This challenge multiplies when treating an opioid-dependent population. We examined whether a novel suspended release local anesthetic, liposomal bupivacaine (LB) would improve pain control and decrease opioid consumption after TKA compared to a standard periarticular injection in opioid-dependent patients. ⋯ LB was not found to be superior to standard PAI in opioid-dependent patients undergoing TKA. This patient population continues to present a challenge even with modern multimodal pain protocols.

Dexamethasone is frequently used for the treatment of postoperative nausea and vomiting and as an adjunct in multimodal postoperative analgesia after total joint arthroplasty; however, the incidence of periprosthetic joint infection (PJI) after the use of perioperative dexamethasone in total joint arthroplasty has yet to be fully elucidated. ⋯ A single intravenous perioperative dose of dexamethasone had no statistically significant difference in the rate of PJI after total hip or knee arthroplasty.

Effect of Patellar Resurfacing on Patellofemoral Crepitus in Posterior-Stabilized Total Knee Arthroplasty.
Patellofemoral crepitus (PC) is a complication of total knee arthroplasty (TKA). Although patellar resurfacing (PR) directly influences the kinematics of the patellofemoral joint, the influence of PR on PC is unclear. The purpose of this study was to investigate the influence of PR on the incidence of PC. ⋯ PR may decrease the incidence of PC by increasing the patellar tilt and medial shift and positioning the patella more closely parallel to the femur. PR is recommended during TKA with this prosthesis.

Preoperative narcotic use has been associated with poor outcomes after total joint arthroplasty (TJA). The purpose of this study is to compare clinical outcomes of patients undergoing elective TJA while concurrently being treated with methadone or buprenorphine/naloxone for prior heroin addiction to a matched control group. ⋯ Equivalent pain control and successful clinical outcome at 1 year can be achieved in patients who use methadone or buprenorphine/naloxone preoperatively.
