Arthroscopically Assisted Double-Bundle Reconstruction Technique for Medial Patellofemoral Ligament

Recurrent patellar dislocation, often caused by medial patellofemoral ligament (MPFL) injury, is commonly treated with MPFL reconstruction. Traditional open techniques are invasive, whereas arthroscopic single-bundle methods may not fully restore native ligament anatomy. This Technical Note presents an improved arthroscopic double-bundle MPFL reconstruction technique featuring (1) dual-anchor patellar fixation for anatomical restoration; (2) fluoroscopy-free femoral tunnel placement (12 mm distal and 6 mm posterior to adductor tubercle); and (3) real-time graft isometry testing to ensure optimal tension. The technique provides biomechanical stability while minimizing invasiveness. Although promising, long-term outcomes require further study, and the procedure demands surgical expertise.
