The management strategies for these depend on factors such as the bar\u2019s location, extent, and residual growth potential. Herein, we describe the case of a 14-year-old male with a valgus knee deformity caused by a distal femoral physeal bar. The patient underwent endoscopic resection of the bar, assisted by computed tomography-based navigation and intraoperative O-arm imaging. This minimally invasive technique facilitated safe and accurate removal of the lesion with less risk of complications such as cortical perforation or injury to adjacent neurovascular structures compared to traditional approaches. The patient experienced favorable postoperative outcomes, including restored knee range of motion and full symptom resolution. This approach demonstrates the clinical value of integrating endoscopy with advanced navigation systems during the surgical treatment of physeal bars.<\/jats:p>","DOI":"10.1093\/jscr\/rjaf972","type":"journal-article","created":{"date-parts":[[2025,11,17]],"date-time":"2025-11-17T12:29:15Z","timestamp":1763382555000},"source":"Crossref","is-referenced-by-count":0,"title":["Endoscopic
