Does Bone Ninja Application Serve as an Alternative to PACS to Measure Preoperative Deformity and Postoperative Alignment Measurements in Case of Total

Description

The presentation discusses the Bone Ninja app, designed to measure post-operative alignment in total knee arthroplasty and potentially serve as an affordable alternative to PACS technology. Developed by the Rubin Institute of Advanced Orthopedics, the app targets healthcare professionals with its user-friendly interface, accessibility for individual use, and utility as a teaching tool. The study details a retrospective analysis involving 50 patients where full-leg radiographs were compared using both the Bone Ninja app and traditional PACS measurements. It reveals that the accuracy of the Bone Ninja app closely matches that of PACS, particularly in assessing key angles related to knee alignment, indicating strong intra- and inter-observer reliability. While it shows promise, the presenter emphasizes that PACS remains the gold standard and suggests further research is needed for broader application. Advantages of Bone Ninja include being cost-effective and easy to use, though it has some limitations like angular measurement precision and current unavailability on Android devices.
