Introduction:
Patellar instability in pediatric patients often requires surgical stabilization. Allograft use in medial patellofemoral ligament reconstruction (MPFLR) remains controversial due to concerns derived from anterior cruciate ligament (ACL) literature.
Methods:
We conducted a retrospective cohort study including 35 patients under 18 years old who underwent MPFLR with allografts between 2019 and 2022. The primary outcome was recurrent dislocation. Secondary outcomes included reoperations and complications.
Results:
One (2.8%) patient had a recurrent dislocation. Six (17.1%) patients experienced complications, with only one requiring revision surgery.
Conclusion:
Allograft MPFLR appears to be a safe and effective option for patellar instability in pediatric patients, with a low rate of failure and complications.
