Abstract:
Accurate correction of cam or combined deformities in femoroacetabular impingement syndrome is essential because under- and over-resection can lead to complications and inferior patient-reported outcomes. Yet, consistent visualization and complete resection remain challenging, with under-resection being a leading cause of revision surgery. Computer-assisted navigation in hip arthroscopy offers the potential to improve accuracy and reduce variability. Recent studies show improved adherence to preoperative plans, reduced residual impingement, and favorable short-term functional scores. However, long-term, patient-centered outcomes remain unknown, and there is limited evidence for improved clinical outcomes compared with traditional freehand fluoroscopic techniques. Drawbacks, including longer operative time and increased system cost, may limit efficiency and raise cost-effectiveness concerns. Larger, prospective studies with extended follow-up are needed to clarify the true clinical impact of computer-assisted navigation and identify the settings in which it may provide maximal benefit.
