Summary
The TightRope fixation technique is superior to hook plate fixation for acromioclavicular (AC) joint dislocations, offering better outcomes and fewer complications. A new predictive model aids in surgical decision-making for AC joint injuries.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Trauma Surgery
Background:
- Acromioclavicular (AC) joint dislocation causes significant pain and functional impairment.
- Rockwood type III injuries require effective surgical management to prevent complications.
Purpose of the Study:
- Compare the efficacy and safety of TightRope fixation versus hook plate fixation for Rockwood type III AC joint dislocations.
- Develop a predictive model for postoperative complications.
Main Methods:
- Retrospective study of 178 patients with Rockwood type III AC joint dislocations.
- Comparison of arthroscopic TightRope fixation (93 patients) and hook plate fixation (85 patients).
- Analysis of perioperative parameters, radiographic outcomes, functional recovery, and complication rates.
Main Results:
- TightRope fixation showed reduced intraoperative trauma, less blood loss, and shorter incisions (p < 0.001).
- Lower postoperative infection rates (2.15% vs. 10.59%) and improved functional scores (ASES, Constant-Murley, UCLA) were observed with TightRope.
- A predictive model identified TightRope as protective against complications (OR=0.42), while blood loss and ACD were risk factors.
Conclusions:
- TightRope fixation provides superior stabilization and functional recovery with fewer complications compared to hook plate fixation for AC joint dislocations.
- The developed predictive model assists in preoperative risk assessment and surgical planning.
