Safe and effective use of active robotics for TKA: Early results of a multicenter study.

Background: A novel active robotic system for total knee arthroplasty (TKA) performs automated milling of bone surfaces. Study objectives were to assess system safety and effectiveness in a US population.

Methods: A multicenter clinical trial was conducted, following 115 patients for at least 6-months.

The Science Behind Mini-Laparoscopic Cholecystectomy.

Background: Mini-laparoscopy (Mini) was pioneered more than 20 years ago. Newer generation mini instruments have recently become available with improved effector tips, a choice of shaft diameters and lengths, better shaft insulation and electrosurgery capability, improved shaft strength and rotation, more ergonomic handles, low-friction trocar options, and improved instrument durability. Whether the use of mini instruments, particularly newer generation instruments, offers advantages for laparoscopic cholecystectomy is the subject of this review.

A Sea Change in Medicine: Current Shifts in the Delivery and Payment of Medical Care.

The Patient Protection and Affordable Care Act and the Triple Aim are driving a shift toward value-based care. Significant financial risk is being transferred from commercial insurers and government payers to hospital systems and independent physician groups. Medicare has developed bundled payment programs, but legislative barriers still impede the implementation of value-based health care.

Mini-Laparoscopy: Instruments and Economics.

Mini-laparoscopy (Mini) was pioneered more than 20 years ago, initially with instruments borrowed from other specialties and subsequently with tools designed specifically for Mini. Early adoption of Mini was inhibited though by the limitations of these first-generation instruments, especially functionality and durability. Newer generation Mini instruments have recently become available with improved effector tips, a choice of shaft diameters and lengths, better shaft insulation and electrosurgery capability, improved shaft strength and rotation, more ergonomic handles, low-friction trocar options, and improved instrument durability.

"Big Operations Using Mini Instruments": The Evolution of Mini Laparoscopy in the Surgical Realm.

Laparoscopy using miniature (2-3.5 mm) instruments was introduced in the late 1980s and early 1990s. Though mini laparoscopy (Mini) created new opportunities for surgical diagnosis and therapy, the limitations of early instruments inhibited widespread adoption.

Evaluation of the Accuracy and Precision of a Next Generation Computer-Assisted Surgical System.

Background: Computer-assisted orthopaedic surgery (CAOS) improves accuracy and reduces outliers in total knee arthroplasty (TKA). However, during the evaluation of CAOS systems, the error generated by the guidance system (hardware and software) has been generally overlooked. Limited information is available on the accuracy and precision of specific CAOS systems with regard to intraoperative final resection measurements.
