[Anterior cruciate ligament-plasty using the "U-dos" technique]

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanical Engineering

Background:

• The knee joint is susceptible to severe injuries, particularly to the anterior cruciate ligament (ACL), which has anteromedial and posterolateral bundles.
• Current ACL reconstruction methods (single or double bundle) lack a definitive gold standard due to similar outcomes.
• The pivot shift test is a key diagnostic tool for ACL injuries.

Purpose of the Study:

• To introduce and evaluate a new anatomical reconstruction technique for anterior cruciate ligament (ACL) injuries, termed "U-dos".
• To achieve normal biomechanical recovery following ACL reconstruction while reducing material costs.
• To assess the clinical efficacy and patient outcomes of the "U-dos" technique.

Main Methods:

• A cross-sectional, observational study involving 20 patients with total ACL injuries.
• ACL reconstruction performed using the "U-dos" technique with bone bank allograft (anterior tibial ligament).
• Patient assessment included the Lysholm scale and the pivot shift test post-surgery.

Main Results:

• 95% (19/20) of patients demonstrated normal to excellent outcomes on the Lysholm scale.
• All patients exhibited negative pivot shift tests, indicating restored knee stability.
• One case reported graft attachment avulsion requiring revision surgery.

Conclusions:

• The "U-dos" technique offers an effective method for anatomical ACL reconstruction.
• This technique shows high success rates in restoring knee function and stability.
• The "U-dos" method presents a cost-effective alternative with favorable clinical results for ACL injuries.
