[Objective]To compare the clinical outcomes of arthroscopic reduction and internal fixation of Hawkins Ⅱ type talus neck fractures with or without robotic assistance.[Methods]From February 2019 to February 2023,65 patients with Hawkins Ⅱ type talus neck fractures were treated by arthroscopic reduction and internal fixation.According to preoperative doctor-patient communication,33 patients had fractures fixed by cannulated screws under robotic assistance(robot group),and the other 32 patients were with conventional methods(the conventional group).The perioperative,follow-up and imaging data were compared between the two groups.[Results]Although there was no significant difference in surgical blood loss,ankle arthroscopic operation time,hospital stay,incision healing quality and complica-tion rate between the two groups(P＞0.05),the robot group proved significantly superior to the conventional group in terms of screw place-ment time[(29.9±5.3)min vs(37.6±6.7)min,P＜0.001],intraoperative fluoroscopy times[(4.6±1.2)times vs(9.7±1.7)times,P＜0.001],and success rate of first screw placement(94.0％vs 56.3％,P＜0.001).There was no significant difference to regain full weight-bearing activities between the two groups(P＞0.05).As time went on,the VAS scores significantly decreased(P＜0.05),while foot varus-valgus range of mo-tion(ROM),ankle-dorsal-plantar flexion ROM and AOFAS scores significantly increased in both groups(P＜0.05),whereas which were not statistically significant between the two groups at 3 months postoperatively and the last follow-up(P＞0.05).Regarding imaging,there were no significant differences in fracture reduction quality,postoperative Takakura degeneration scale and adverse signs between the two groups(P＞0.05).[Conclusion]Robot-assisted arthroscopic reduction and internal fixation of Hawkins Ⅱ type talus neck fractures does shorten the fixation time,reduce the number of fluoroscopy,and improve the success rate of one time screw placement.
