The effect of using patient-specific guides for total knee replacement without hardware removal in complex post-traumatic arthritis: an in-vitro study

Key Points

• The study aims to evaluate the effectiveness of patient-specific guides in total knee replacement without hardware removal.
• Conducted an in-vitro experimental study to assess alignment accuracy.
• Compared patient-specific guides to traditional alignment techniques.
• Analyzed the impact of retained hardware on surgical precision.
• Patient-specific guides achieved higher alignment accuracy than traditional methods.
• Even with retained hardware, PSGs offered improved precision.
• Workflow efficiency was enhanced when using patient-specific guides.
