Is Patient-specific Instrumentation for TKA Ready for Prime Time?

Literature review finds more data needed to justify routine use

Maureen Leahy

Most total knee arthroplasties (TKAs) for end-stage knee arthritis are successfully performed using standard instruments, with patients reporting significant pain relief and enhanced mobility. Newer patient-specific instrumentation (PSI) is designed to further improve TKA by enabling orthopaedic surgeons to customize surgery to a patient’s individual anatomy. The goal is a faster procedure that reduces the risk of implant malpositioning, increases alignment accuracy, and improves patient outcomes. According to a review article in the September 2013 issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS), however, additional data are needed before widespread use of these instruments can be recommended.
