Dr. Garcia demonstrates his MPFL reconstruction technique to treat recurrent patella dislocations.

This video features Dr. Grant H. Garcia demonstrating an MPFL (medial patellofemoral ligament) reconstruction technique to treat recurrent patella dislocations.
The procedure utilizes a semitendinosus allograft and involves the following steps:
- Making a small arthrotomy in the superior portion of the patella to prepare the bone surface.
- Placing two suture anchors into the patella to recreate the previous anatomic MPFL.
- Identifying "Schöttle's point" under fluoroscopy to appropriately place a guide pin and reamer at the medial portion of the knee.
- Using suture tapes to ensure isometric tension before final reaming.
- Whip-stitching the allograft over the patella and securing it to the anchors with a tension slide technique.
- Passing the graft through the prepared tunnel between layers two and three, then securing it with a PEEK screw at roughly 45 degrees, taking care not to over-constrain the knee.
- Checking the patient's stability at multiple angles (0, 45, and 90 degrees) and performing a final arthroscopy to confirm the graft is properly positioned outside the joint space.
