Pelvic tilt affects acetabular anteversion, and thus total hip arthroplasty (THA) dislocation risk. The pubic symphysis-sacrococcygeal distance (PSCD) is an indicator of pelvic tilt, and a PSCD < 0 mm (ie, excessive posterior pelvic tilt) is associated with a 3.7-fold increase in postoperative dislocation rate. However, it is not known if the direct anterior (DA) approach might reduce this dislocation rate, specifically in high-risk populations such as negative PSCD. ⋯ We demonstrate no increased risk for THA dislocation in patients with a PSCD < 0 mm who have undergone a DA approach. These data would suggest a protective effect of the DA approach against dislocation, even in historically high-risk populations.

Efficacy of Two Unique Combinations of Nerve Blocks on Postoperative Pain and Functional Outcome After Total Knee Arthroplasty: A Prospective, Double-Blind, Randomized Controlled Study.
This study aimed to explore the efficacy of two unique combinations of nerve blocks on postoperative pain and functional outcome after total knee arthroplasty (TKA). ⋯ Adding ONB or ONB + LFCNB to ACB + IPACK can statistically reduce morphine consumption, improve early pain relief, and functional recovery. However, the absolute change in morphine consumption, VAS scores, and QoR-15 scores did not exceed the MCIDs. Based on our findings and considering the sample size of this study, there is not enough clinical evidence to support the triple or quadruple nerve block use within a multimodal analgesic pathway after TKA.

Femoral neck fractures (FNFs) are one of the most common injuries in the elderly. Treatment is either internal fixation or primary arthroplasty. The main aim of this study is to assess the risk factors associated with fixation failure leading to further arthroplasty in FNFs treated with cannulated screws. ⋯ Displaced fractures and fractures with a preoperative posterior tilt of <0° or ≥20° have a considerably increased risk of reoperation and conversion to arthroplasty. Primary arthroplasty should be considered as treatment for displaced FNFs and fractures with >20° or <0° posterior tilt, especially in fragile patients, to avoid further operations.

The effect of pre-existing mental illness on outpatient surgical outcomes is not well characterized. The objective of this study was to evaluate the association between pre-existing mental illness diagnosis and postoperative complications after outpatient total knee (TKA) and total hip arthroplasty (THA) and 2) compare with inpatient total joint arthroplasty (TJA). ⋯ III.

The optimal type of dressing in the setting of total joint arthroplasty (TJA) remains uncertain. The aim of this network meta-analysis was to compare various wound dressings and identify the optimal type of dressings for blister reduction and prevention of periprosthetic joint infection (PJI) in patients after TJA. ⋯ Based on the evidence from our analysis, an antimicrobial dressing is the optimal dressing to prevent PJI. If negative-pressure wound therapy is used, surgeons should be aware of an increased incidence of blister formation. Further studies should focus on the alginate versus hydrofiber and hydrocolloid dressing to determine the optimal dressing to reduce blisters.
