Comparative Study
Femoral Nerve Block Versus Long-Acting Wound Infiltration in Total Knee Arthroplasty.
Multimodal wound infiltration analgesic techniques have attracted growing interest for applications in total knee arthroplasty (TKA). A benefit of using wound infiltration instead of femoral nerve block (FNB) in a multimodal pain control regimen is the limitation of muscle strength impairment to the surgical area, which will focus the pain control effort and may provide the opportunity for easier rehabilitation and earlier discharge from the hospital. The current study directly compares patients undergoing TKA who are given a continuous FNB with those who were administered an injection of liposomal bupivacaine infiltration. ⋯ The average number of narcotic doses and the total number of narcotics consumed was greater in the FNB group (P<.001). Average visual analog scale pain scores trended higher for patients in the FNB group (2.29 vs 1.93) overall and for each day postoperatively up to day 5, although the overall difference was not significant in this study sample (P=.115). The results of the current study support the conclusion that long-acting liposome bupivacaine infiltration gives comparable postoperative analgesia compared with a continuous FNB, but with significantly less narcotic medication.

Overgrowth of epidural fat, known as spinal epidural lipomatosis (SEL), can cause symptomatic compression of the spinal cord, conus medullaris, or cauda equina. Suggested predisposing factors such as obesity, steroid use, and diabetes mellitus have been based on a few reported cases, many of which were not surgically confirmed. There is a paucity of epidemiological data in surgically confirmed cases for this disorder. ⋯ This series represents the largest of its kind reported to date. Because symptom duration was the only difference noted, it is postulated to be the result of lack of awareness of SEL. Future prospective study in a larger group of patients is warranted.

Comparative Study
Pain After Anatomic Total Shoulder Arthroplasty Versus Reverse Total Shoulder Arthroplasty.
As anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) become increasingly common, differences between the 2 procedures are of importance. The purpose of this study was to determine differences in acute pain levels between patients undergoing aTSA and rTSA. Sixty patients undergoing aTSA or rTSA were assessed for participation. ⋯ However, after 4 hours postoperatively, no significant differences in pain scores or opioid consumption were found. These findings suggest that patients undergoing aTSA or rTSA have similar postoperative pain profiles. Patients who are prescribed narcotics before shoulder arthroplasty are at an increased risk for postoperative opioid demand. [Orthopedics. 2019; 42(2):e247-e252.].

Orthopedic surgeons frequently encounter medical malpractice claims. The purpose of this study was to assess trends and risk factors in lawsuits brought against orthopedic surgeons using a national legal database. A legal research service was used to search publicly available settlement and verdict reports between 1988 and 2013 by terms "orthopaedic or orthopedic" and "malpractice." Temporal trends were evaluated, and logistic regression was used to identify independent risk factors for case outcomes. ⋯ When analyzing data by state and region, adjusted for population, northeastern states had a higher frequency of lawsuits. Malpractice liability has increased during the past 3 decades while orthopedic surgeons continue to win most of the cases making it to court. As patients search for medical care via publicly available information, it is important for orthopedic surgeons to understand what aspects of their own practice carry different risks of litigation.

Review Meta Analysis
Efficacy of Intra-articular Local Anesthetics in Total Knee Arthroplasty.
Pain management after total knee arthroplasty (TKA) remains among the most important challenges for patients with TKA. Intra-articular local anesthetic has been shown to reduce postoperative pain following TKA. However, studies report conflicting results. ⋯ The results showed that, compared with the placebo group, the single local anesthetic group had a significant lower pain score with rest at 4, 8, 24, and 48 hours; less opioid consumption at 24, 48, and 72 hours postoperatively; and greater range of motion at 24, 48, and 72 hours. There were no significant differences between the 2 groups in length of hospital stay, nausea and vomiting, pruritus, sedation, or deep venous thrombosis. The study findings showed that pain relief after TKA was significantly better with intra-articular local anesthetic than with placebo.
