Total knee arthroplasty volume is increasing significantly in the United States. Reducing hospital length of stay may represent the best method for accommodating expanding volume and reducing costs. We hypothesized that tailoring a clinical pathway to facilitate early ambulation would decrease costs and resource utilization. ⋯ The data demonstrate that tailored clinical pathways designed to facilitate early ambulation can reduce hospital length of stay, reduce opioid consumption, reduce antiemetic use, and improve pain control. The results establish that refined clinical pathways can assist in improving care while increasing value to patients, providers, and systems.

Chronic obstructive pulmonary disease (COPD) is a major global health issue and a leading cause of morbidity and mortality. Patients with COPD are at increased risk of complications following surgery. The purpose of this study is to evaluate the postoperative total knee arthroplasty (TKA) outcomes in these patients in comparison to a non-COPD matching cohort. Specifically, we asked the following questions: (1) "Is COPD associated with adverse perioperative outcomes?" and (2) "Does COPD increase the risk of short-term complications following TKA?" ⋯ Patients with COPD are more likely to experience postoperative complications following TKA when compared to non-COPD patients. Pulmonary evaluation and optimization are crucial to minimize adverse events from occurring in this difficult-to-treat population.

As the number of total hip and knee arthroplasty cases increases, it is important to understand the burden of factors that impact patient outcomes of these procedures. This article examined the time trends in key demographics, clinical characteristics, comorbidity burden (Deyo-Charlson Comorbidity Index [CCI]), and presence of depression in patients undergoing primary total hip arthroplasty and total knee arthroplasty using population-based, all-payer inpatient database, California Healthcare Cost and Utilization Project, from 2007 to 2010. ⋯ Despite the younger age of the joint arthroplasty population over time, we found increased prevalence of depression and comorbidity scores but shorter LOS. Further study is needed to determine the impact of the changing demographics of the total joint population and the best strategies to optimize their outcome with these procedures.

Risk Adjustment Is Necessary in Medicare Bundled Payment Models for Total Hip and Knee Arthroplasty.
Concerns exist that high-risk patients in alternative payment models may face difficulties with access to care without proper risk adjustment. The purpose of this study is to identify the effect of medical and orthopedic specific risk factors on the cost of a 90-day episode of care following total hip (THA) and knee arthroplasty (TKA). ⋯ Certain comorbidities and orthopedic risk factors increase 90-day episode-of-care costs in the Medicare population. The current lack of proper risk stratification could be a powerful driver of decreased access to care for our most medically challenged members of society.

Elevated metal ion levels have been associated with the presence of adverse local tissue reactions in patients with metal-on-polyethylene (MoP) total hip arthroplasty (THA) secondary to corrosion at head-neck taper junction. Patients are frequently concerned with their elevated systemic metal ion levels. This study investigated the rate of decline of serum cobalt and chromium ion levels after revision surgery. ⋯ At 3 months after revision surgery, cobalt and chromium ion levels declined by 34% and 8% of prerevision level, respectively. This study provides evidence-based practical information for surgeons to provide MoP THA patients when considering revision surgery for head-neck taper corrosion.
