removal techniques. In Group A, the cannulated screws were removed under US guidance, while in Group B, they were removed under direct visualization using a traditional incision. The operative time, blood loss, success rate of removal, radiation frequency, and incision length were statistically analyzed. Knee function was evaluated using the Knee Society Score.Results: 53 patients aged 15.3±0.1 years were included in this study. Group A showed 50% shorter incision length (1.5 vs 3.0 cm, p=0.005) and average screw incisions (0.5 vs 1.0 cm, p=0.007), along with complete elimination of preoperative radiation exposure (0 vs 2 times, p<0.001) and dose (0 vs 0.102 mGy, p<0.001) compared to Group B. Participants in Group A had no postoperative complications, whereas one patient in Group B had an incision infection; however, no significant difference was observed between the groups. Discussion: US-guided cannulated screw removal can be used in children with proximal tibial fractures, significantly reducing the preoperative radiation time and dose while minimizing the incisional length.
