Double-Bundle Artificial Medial Patellofemoral Ligament Reconstruction Using a Femoral Suture-Sliding Anchor and...

Double-bundle medial patellofemoral ligament reconstruction with artificial ligaments is a minimally invasive surgical option for recurrent patellar dislocation. However, it carries a risk of over-tensioning, which may lead to restricted patellar mobility and anterior knee pain. Here, we describe a technique that combines an artificial ligament with a femoral suture-sliding anchor and double-tunnel patellar fixation. This construct enables staged tension adjustment, thereby mitigating the risk of over-tensioning. By introducing the adjustability of the artificial double-bundle graft at the patellar site, this method offers a reproducible means of fine-tuning graft tension and avoiding over-constraint in double-bundle artificial medial patellofemoral ligament reconstruction.
