Medial Patellofemoral Reconstruction Techniques for Patellar Instability

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Anatomy

Background:

• The medial patellofemoral complex (MPFC) is crucial for patellar stability.
• It comprises the medial patellofemoral ligament (MPFL) and medial quadriceps tendon femoral ligament (MQTFL).
• Variability in attachment necessitates understanding consistent anatomical landmarks for reconstruction.

Purpose of the Study:

• To review the anatomy of the MPFC.
• To detail various surgical techniques for MPFC reconstruction.
• To highlight critical factors for successful surgical outcomes in patellar instability.

Main Methods:

• Review of anatomical structures of the MPFC.
• Description of graft configurations, types, and fixation methods for MPFC reconstruction.
• Discussion of surgical pearls and pitfalls.

Main Results:

• Multiple reconstruction techniques using diverse grafts and fixation devices yield good outcomes.
• Anatomic femoral tunnel placement is critical.
• Avoiding graft over-tensioning and managing morphological risk factors are essential.

Conclusions:

• Successful MPFC reconstruction depends on precise surgical technique and addressing patient-specific anatomy.
• Various graft options and fixation sites can achieve favorable results for patellar instability.
• Understanding anatomical nuances is key to optimizing surgical treatment.
