Fracture of Contemporary Femoral Stems: Common Trends in This Rare Occurrence.

Background: Fracture of contemporary femoral stems is a rare occurrence in total hip arthroplasty. A knowledge gap remains regarding manufacturing, patient, and surgeon factors that may contribute to the increased risk of this complication.

Methods: We analyzed 13 contemporary fractured porous-coated femoral stems of various designs to determine cause and contributing factors of mechanical failure.

Robotic-assisted total hip arthroplasty: an economic analysis.

To evaluate 90-day episode-of-care (EOC) resource consumption in robotic-assisted total hip arthroplasty (RATHA) versus manual total hip arthroplasty (mTHA). THA procedures were identified in Medicare 100% data. After propensity score matching 1:5, 938 RATHA and 4,670 mTHA cases were included.

Robotic arm-assisted knee surgery: an economic analysis.

Objectives: Previous studies on Medicare populations have shown improved outcomes and decreased 90-day episode-of-care costs with robotic arm-assisted total knee arthroplasty (RATKA). The purpose of this study was to evaluate expenditures and utilization following RATKA in the population younger than 65 years.

Study Design: This is a retrospective longitudinal analysis of a commercial claims data set.

The Current Status of Cell-Based Therapies for Primary Knee Osteoarthritis.

There is a growing interest in cell therapy for knee osteoarthritis. This study systematically reviews the current status of cell-based therapies. The authors review treatment modalities, clinical outcomes, and the economics of cell therapy.

Stem Cells and Platelet-rich Plasma for Knee Osteoarthritis: Prevalence and Cost in South Florida.

Introduction: The use of stem cell therapy (SCT) and platelet-rich plasma (PRP) injection for knee osteoarthritis (OA) is extremely controversial and at best experimental stage. These treatments are being offered across the nation for "cash-only payments." Our objectives were to determine (1) what proportion of board-certified orthopedic surgeons in Miami-Dade County offer SCT or PRP and (2) how much do practices charge for these services.
