Randomized Controlled Trial Comparative Study
Comparison of Local Infiltration Analgesia With Femoral Nerve Block for Total Knee Arthroplasty: A Prospective, Randomized Clinical Trial.
Total knee arthroplasty (TKA) is usually associated with severe postoperative pain, which can prevent rehabilitation of patients' knee function and influence the satisfaction of surgery. Local infiltration analgesia (LIA) as a new method to managing postoperative pain has been applied in clinical practice recently. However, the safety and efficacy of LIA compared with femoral nerve block (FNB) in postoperative pain management of TKA still remains controversial. Thus, we conducted an original clinical trial to compare LIA and FNB. ⋯ Our research showed that no significant differences were observed between the 2 treatment groups. LIA could provide a similar analgesic effect to FNBs with a low incidence of complications.

There has been much attention paid to the ability to optimize outcomes, limit complications, and reduce costs within the episode of care after total joint arthroplasty. Limiting the duration of postoperative hospitalization as well as reducing emergency department (ED) visits and readmissions are additional considerations in the paradigm of cost containment. Our purpose was to evaluate the safety of early hospital discharge after primary total knee arthroplasty (TKA) and to identify the diagnoses responsible for ED visits and readmissions in the postoperative period. ⋯ Among patients undergoing primary TKA, it is the health of the patient, and not their resultant LOS, that correlates to return events. The ED is overused for complaints that may otherwise be managed as effectively and more cost efficiently in outpatient settings. Cost containment must include unnecessary utilization of the ED.

Data addressing risk factors predictive of mortality and reoperation after periprosthetic femur fractures (PPFxs) are lacking. This study examined survivorship and risk ratios for mortality and reoperation after surgical treatment for PPFx and associated clinical risk factors. ⋯ After PPFx, patients have a 24% risk of either death or reoperation at 1 year. Factors contributing to increased mortality are nonmodifiable. Risk of reoperation is minimized with greater span of fixation and performance of revision arthroplasty.

Surgery is in a constant continuum of innovation with refinement of technique and instrumentation. Arthroplasty surgery potentially represents an area with highly innovative process. This study highlights key area of innovation in knee arthroplasty over the past 35 years using patent and publication metrics. Growth rates and patterns are analyzed. Patents are correlated to publications as a measure of scientific support. ⋯ Identifying trends in emerging technologies is possible using patent metrics and is useful information for training and regulatory bodies. The decline in ratio of publications to patents and the uninterrupted growth of PSI are developments that may warrant further investigation.

Randomized Controlled Trial
The Effect of Perioperative Corticosteroids in Total Hip Arthroplasty: A Prospective Double-Blind Placebo Controlled Pilot Study.
Surgery produces a rapid rise in interleukin 6 (IL-6) which may increase the risk of deep vein thrombosis and medical complications. Perioperative corticosteroids suppress IL-6 release in patients undergoing total knee arthroplasty. This study evaluates the effects of a perioperative corticosteroid regimen on IL-6 formation, thrombogenesis, fibrinolysis, and clinical outcomes in patients undergoing unilateral, uncemented, total hip arthroplasty. ⋯ The use of corticosteroids was associated with a statistically significant decrease in IL-6 at 6 and 24 hours postoperatively but did not affect thrombogenic markers. The study group had improved postoperative analgesia and a trend toward improved functional outcome at 3 months postoperatively.
