Medial patellofemoral ligament reconstruction provided patellar stability in pediatric patients
PRAGUE — Among skeletally immature patients with patellar instability, medial patellofemoral ligament reconstruction resulted in good outcomes in terms of patellar stability, according to results presented at the 16th EFORT Congress.
“MPFL [medial patellofemoral ligament] reconstruction seems like a very safe procedure, [and] complications were very rare,” Petri Sillanpää, MD, PhD, said in his presentation here. “MPFL reconstruction with adductor magnus autograft seems to be very reproducible, it does not interfere with femoral physis and may be considered as a good method for patellar instability in the pediatric population.”
Between 2008 and 2012, Sillanpää and colleagues performed MPFL reconstruction in 30 knees among 26 skeletally immature patients with patellar instability. The study’s primary endpoint measure was Kujala score, and the secondary endpoint was the rate of redislocation after surgery.
Sillanpää noted the Kujala score improved from a mean of 74 points to a mean of 92 points, indicating statistically and clinically significant improvements.

“There were four patients with patella redislocation occurred between 6 and 22 months after surgery,” Sillanpää said. “All of those four redislocation cases have very high rate of trochlear dysplasia.”
Results showed a patient satisfaction rate of 88%, according to Sillanpää. – by Casey Tingle
