PSI uses preop MRI/CT to fabricate custom cutting jigs. Goal: improve accuracy, reduce OR time/inventory; evidence shows marginal accuracy gains without clear functional benefit. Limitations: cost, imaging/manufacture time, error propagation if imaging off. Best reserved for complex deformity or limited instrument settings. Distinguish PSI (custom guides) from custom implants (rare).
