Abstract
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.
