Lateral patellofemoral ligament reconstruction

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomedical Engineering

Background:

• Medial dislocation of the patella is a disabling condition often associated with prior failed lateral retinacular release.
• Treating medial patellar subluxation can be challenging, with initial repairs often failing to provide lasting stability.
• Recurrence of medial patellar excursion is common after direct lateral retinaculum repair.

Purpose of the Study:

• To describe a novel, reproducible technique for lateral patellofemoral ligament reconstruction using autogenous tissue.
• To evaluate the efficacy of this reconstruction in managing medial patellar instability following failed lateral retinacular release.

Main Methods:

• Development of a surgical technique based on established ligament reconstruction principles.
• Utilizing autogenous tissue for the reconstruction of the lateral patellofemoral ligament.
• Clinical assessment of symptom elimination related to medial patellar instability.

Main Results:

• The described technique provides a method for reconstructing the lateral patellofemoral ligament.
• This reconstruction is effective in eliminating symptoms associated with medial patellar instability post-failed lateral retinacular release.
• The procedure is considered a salvage option, not addressing the primary pathomechanics.

Conclusions:

• Lateral patellofemoral ligament reconstruction is a viable salvage procedure for persistent medial patellar instability.
• The technique offers a reproducible solution for symptom management after failed lateral retinacular release.
• It is crucial to recognize that this method addresses instability but not the root cause of patellofemoral symptoms.
