Summary
This study presents a new technique for medial patellofemoral ligament (MPFL) reconstruction using quadriceps tendon and a PEEK device. This method offers a quick, safe, and reliable solution for MPFL repair in patients with patellar instability.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomedical Engineering
Background:
- The medial patellofemoral ligament (MPFL) is crucial for stabilizing the patellofemoral joint.
- MPFL rupture occurs in nearly all acute patellar dislocations, necessitating effective reconstruction methods.
Purpose of the Study:
- To describe a novel technique for MPFL reconstruction.
- To evaluate the efficacy of using a threadless expanding PEEK interference device for MPFL tenodesis.
Main Methods:
- Reconstruction of the MPFL using autologous quadriceps tendon.
- Fixation of the tendon graft within a femoral drill hole using a threadless expanding PEEK interference device.
Main Results:
- The described technique provides a means for MPFL reconstruction.
- The PEEK interference device facilitates secure and straightforward graft fixation.
Conclusions:
- MPFL reconstruction with quadriceps tendon using a threadless expanding PEEK device is a viable surgical option.
- This tenodesis procedure is characterized by its speed, safety, and reliability in clinical practice.
