Patient-Specific Instrumentation Does Not Improve Alignment Compared to the Extramedullary Foot Holder for the INBONE II Total Ankle Arthroplasty
In this study of stemmed TAA implants, surgeons achieved alignment generally consistent with PSI predictions. PSI adequately predicted implant size. For most cases, PSI achieved similar alignment and correction of deformity compared with standard instrumentation. PSI did not improve radiographic alignment compared with traditional instrumentation and was associated with longer operative times, possibly reflecting the primary surgeon's early experience with the technique. Each surgeon should select PSI or the standard jig based on their experience and preference.
