Although PSI has shown some success in hip and knee arthroplasty, it doesn’t necessarily demonstrate the same success rates in shoulder. Stephanie Muh, MD shares her preference for her practice and supports it by reviewing the study Accuracy of patient-specific instrumentation in shoulder arthroplasty: a systematic review and meta-analysis.
The success of patient-specific instrumentation (PSI) in total hip and knee arthroplasty has naturally led to the surge of growth of PSI in shoulder arthroplasty. However, the key question of whether PSI is better than standard instrumentation is unknown.
