Computer-Assisted / Navigation-based Arthroplasty

Computer-assisted surgery (CAS) improves component alignment in TKA/THA. Techniques: imageless and CT-based navigation. Benefits: improved mechanical axis alignment, reduced outliers, useful in deformity. Limitations: longer OR time, cost, learning curve; functional/survivorship benefits inconsistent. Adjunct tool especially in complex anatomy.
