Summary

This study presents a new surgical technique for medial patellofemoral ligament (MPFL) reconstruction using a gracilis allograft and adjustable loop fixation. This method effectively treats patellar instability and allows for early patient rehabilitation.

Area Of Science

Orthopedic Surgery
Sports Medicine
Biomedical Engineering

Background

Patellar instability is often caused by medial patellofemoral ligament (MPFL) tears or attenuation.
MPFL reconstruction is the primary surgical approach to restore stability and prevent lateral patellar translation.
Existing techniques may have associated complications, necessitating refined surgical methods.

Purpose Of The Study

To describe a novel technique for MPFL reconstruction combined with lateral retinacular lengthening.
To utilize a gracilis allograft and adjustable loop cortical femoral fixation for enhanced patellar stability.
To evaluate the efficacy and safety of this approach in managing patellar instability.

Main Methods

A lateral parapatellar approach was employed for the surgical procedure.
Gracilis allograft was used for MPFL reconstruction.
Adjustable loop cortical fixation was implemented for secure graft placement.
Concomitant lateral retinacular lengthening was performed to optimize soft tissue tension.

Main Results

The described technique allows for reliable retensioning of medial and lateral patellar soft tissues.
This method avoids complications associated with traditional interference screw fixation.
A strong MPFL construct is achieved, facilitating early rehabilitation.

Conclusions

The described MPFL reconstruction technique with adjustable loop fixation and lateral retinacular lengthening is effective for treating patellar instability.
This approach offers a reliable and safe alternative to existing methods.
Patients can achieve early aggressive rehabilitation and return to activities following this procedure.
