Changes in spinal alignment and pelvic tilt alter acetabular orientation in predictable ways, which may have implications on stability of total hip arthroplasty (THA). Patients with sagittal spinal deformity represent a subset of patients who may be at particularly high risk of THA instability because of postural compensation for abnormal spinal alignment. ⋯ In this cohort, patients with THA and concomitant spinal deformity have a particularly high rate of THA instability despite having an acetabular cup position traditionally thought of as within acceptable alignment. This dislocation risk may be driven by the degree of spinal deformity and by spinopelvic compensation. Surgeons should anticipate potential instability after hip arthroplasty and adjust their surgical plan accordingly.

Randomized Controlled Trial
Does Patient Perception Differ Following Adductor Canal Block and Femoral Nerve Block in Total Knee Arthroplasty? A Simultaneous Bilateral Randomized Study.
Femoral nerve block (FNB) has been used as part of the multimodal analgesia after total knee arthroplasty (TKA), but leads to weakness in the quadriceps muscles. Recently, adductor canal block (ACB) was reported to provide effective pain relief while sparing the strength of the quadriceps. This simultaneous bilateral randomized study investigated whether patients perceived differences between ACB and the FNB after same-day bilateral TKA. ⋯ This simultaneous bilateral randomized study demonstrates that patients did not perceive differences in pain level, but experienced substantial differences in quadriceps strength recovery between knees during the first 48 h (Identifier: NCT02513082).

Poorly controlled postoperative pain may adversely affect total joint arthroplasty (TJA) patients' outcomes and associated healthcare cost. Understanding effective pain management after surgery is important to patients, surgeons, and hospitals. We evaluated patient-reported receipt of preoperative pain management information in a national prospective cohort evaluating postoperative pain and function following elective TJA. ⋯ Forty-four percent of the patients reported that they did not receive/received unhelpful information regarding postoperative pain management, highlighting a need for improved patient education. In this sample, the lack of pain management information was associated with poorer 6-month postoperative function.

Comparative Study
Comparison of Outpatient vs Inpatient Total Knee Arthroplasty: An ACS-NSQIP Analysis.
There has been a recent surge of interest in performing primary total knee arthroplasty (TKA) in the outpatient setting to reduce cost and increase patient satisfaction. Detailed information on the safety of outpatient TKA in large sample sizes is scarce. ⋯ Based on the perioperative outcome measures studied here, outpatient TKA can be appropriately considered in select patients based on rates of overall perioperative adverse events and readmissions. However, higher surveillance of these patients postdischarge may be warranted.

In recent years, bundled payment reimbursement models have been used to address the unsustainable rising cost of healthcare. Centers for Medicare and Medicaid Services initiatives, such as Bundled Payment for Care Improvement Program, have already demonstrated their ability to create financial and performance accountability in the public sector. ⋯ Bundled payment strategies provide incentives for physicians and healthcare professionals to eliminate unnecessary services and reduce costs. This article discusses our experience at a private institution with transitioning to a bundled payment program, while identifying the challenges and strategies associated with a successful implementation.
