Efficacy of Arthroscopic Modified Kite Technique Combined with Triple-Button in the Treatment of Acute Acromioclavicular Joint Dislocation
Objective To evaluate the clinical outcomes of arthroscopically assisted Improved Kite technique combined with Triple-button fixation in the surgical management of acute acromioclavicular joint dislocations.Methods A retrospective analysis was conducted on 33 patients treated with arthroscopic coracoclavicular ligament reconstruction using the Improved Kite technique combined with Triple-button fixation at Baoding No.1 Central Hospital and the Third Hospital of Peking University between December 2019 and May 2022.The study cohort included 21 males and 12 females,with ages ranging from 21 to 58 years(mean age:38.20±0.60 years).The affected side was the left shoulder in 20 patients and the right shoulder in 13 patients.Based on the Rockwood classification,16 patients were classified as Type Ⅲ and 17 as Type V dislocations.Preoperative and final follow-up assessments included the Visual Analogue Scale(VAS)for pain,Constant-Murley Scores(CMS)for shoulder function,and range of motion(ROM)measurements.Preoperative,postoperative,and final follow-up X-rays of the injured shoulder joint were obtained to measure the coracoclavicular distance(CCD)and acromioclavicular distance(ACD).Additionally,any complications encountered during or after the procedure were recorded.Results The 33 patients were followed up for 6 to 19 months,with a mean follow-up duration of(13.36±0.28)months.All surgical incisions healed without infection,and no complications such as recurrent dislocation,clavicle fractures,or coracoid fractures were observed.The VAS score significantly decreased from(7.44±0.53)preoperatively to(0.56±0.73)at the final follow-up(P＜0.001).The CMS improved significantly from(35.11±1.45)preoperatively to(90.11±2.80)at the final follow-up(P＜0.001).The forward elevation ROM of the injured shoulder improved significantly from(47.22±9.39)° preoperatively to(178.89±3.33)° at the final follow-up(P＜0.001).The coracoclavicular distance(CCD)decreased significantly from(16.73±3.73)mm preoperatively to(10.61±3.24)mm at the final follow-up(P＜0.001).Similarly,the acromioclavicular distance(ACD)also decreased significantly from(12.18±3.34)mm preoperatively to(6.49±2.64)mm at the final follow-up(P＜0.001).Conclusion The arthroscopically assisted Improved Kite technique combined with Triple-button fixation for the treatment of acute acromioclavicular joint dislocations is a safe and reproducible procedure that achieves satisfactory short-term clinical outcomes.However,further observation is required to assess its long-term efficacy.
