Randomized Controlled Trial Comparative Study
Preemptive Femoral Nerve Block Could Reduce the Rebound Pain After Periarticular Injection in Total Knee Arthroplasty.
We evaluated the effectiveness of postoperative pain management using intraoperative periarticular injection (PAI) and/or electromyography-guided preoperative femoral nerve block (FNB) in knees undergoing total knee arthroplasty (TKA). ⋯ PAI was more effective than FNB during the early (0-8 hours) postoperative period after TKA. Patients treated with PAI, however, experienced rebound pain at 24 hours. The combination of PAI and FNB may provide greater postoperative pain management than either alone for the first 24 hours after TKA.

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.

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.

Numerous series have documented short-term successes with cementless total hip arthroplasty (THA) and subtrochanteric shortening osteotomy for Crowe IV developmental dysplasia of the hip (DDH). However, data are lacking regarding long-term implant fixation and patient function. In this study, we aimed to evaluate the 10-year results of cementless THA with simultaneous subtrochanteric shortening osteotomy for Crowe IV DDH. ⋯ In the longest series to date, cementless THA combined with a subtrochanteric femoral shortening osteotomy in patients with a high hip dislocation secondary to dysplasia was associated with high rates of successful implant fixation and stable clinical improvement.

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.
