Although some bundled payment models have had success in total joint arthroplasty, concerns exist about access to care for higher cost patients who use more resources. The purpose of this study is to determine whether Medicaid patients have increased hospital costs and more resource utilization in a 90-day episode of care than Medicare or privately insured patients. ⋯ Because of increased hospital costs, current bundled payment models should not include Medicaid patients because of concerns about patient selection and access to care. Further study is needed to determine whether bundling Medicaid arthroplasty costs in a stand-alone program with a separate target price will result in improved outcomes and decreased costs.

Randomized Controlled Trial Multicenter Study
Total Knee Arthroplasty Using Bicruciate-Stabilized or Posterior-Stabilized Knee Implants Provided Comparable Outcomes at 2 Years: A Prospective, Multicenter, Randomized, Controlled, Clinical Trial of Patient Outcomes.
The bicruciate-stabilized (BCS) knee arthroplasty was developed to replicate normal knee kinematics. We examined the hypothesis that patients with osteoarthritis requiring total knee arthroplasty (TKA) will have better functional outcome and satisfaction with the BCS implant compared with an established posterior cruciate-stabilized implant. ⋯ There was no evidence of clinical superiority of one implant over the other at 2 years.

Multicenter Study Clinical Trial
The Leukocyte Esterase Strip Test has Practical Value for Diagnosing Periprosthetic Joint Infection After Total Knee Arthroplasty: A Multicenter Study.
Leukocyte esterase (LE) was recently reported to be an accurate marker for diagnosing periprosthetic joint infection (PJI) as defined by the Musculoskeletal Infection Society (MSIS) criteria. However, the diagnostic value of the LE test for PJI after total knee arthroplasty (TKA), the reliability of the subjective visual interpretation of the LE test, and the correlation between the LE test results and the current MSIS criteria remain unclear. ⋯ The LE test has high diagnostic value for diagnosing PJI after TKA. Subjective visual interpretation of the LE test was reliable and valid for the current battery of PJI diagnostic tests according to the MSIS criteria.

The Medicare program has initiated Comprehensive Care for Joint Replacement (CJR), a bundled payment mandate for lower extremity joint replacements. We sought to determine the degree to which hospitals will invest in care redesign in response to CJR, and to project its economic impacts. ⋯ CJR is projected to have a negligible impact on total health care expenditures for lower extremity joint replacements. Further research will be required to assess the actual care management strategies adopted by CJR hospitals.

Multicenter Study Comparative Study
No Clinical Difference Comparing General, Regional, and Combination Anesthesia in Hip Arthroplasty: A Multicenter Cohort-Study Regarding Perioperative Pain Management and Patient Satisfaction.
Steadily increasing numbers of hip arthroplasties are reported in the past years. Different types of anesthetic methods for surgery itself as well as pain management programs have been established. It is one of the main goals to reduce postoperative pain levels and guarantee better and faster mobilization in the postoperative period. The present study aims to compare the use of general and regional spinal anesthesia and their combination regarding perioperative pain management and patient satisfaction. ⋯ We were able to show a highly significant advantage in the use of regional or the combination of regional and general anesthesia in comparison with general anesthesia alone in hip arthroplasty regarding patients' satisfaction and the requirement of opioid pain medication, although maybe below clinical relevance.
