Abstract
Medial patellofemoral ligament reconstruction is a standard treatment option for patients with patellar
instability. The main purpose of this study was to determine whether isolated anatomic medial
patellofemoral ligament reconstruction using double folded, four-strand plantaris tendon autograft restores
patellar stability in adolescent patients. Plantaris tendon autografts were harvested through proximal
approach and used in four adolescent patients. A four-strand autograft was prepared in a double-limbed
configuration and fixed on the patella and the femur with suture anchors and interference screws,
respectively. The mean Kujala score improved significantly from 44 ± 24 SD (range, 19 to 69) points
preoperatively to 94 ± 10 SD (range, 78 to 100) points postoperatively (P< 0.001). All patients reported
excellent subjective outcomes and returned to their pre-injury level of sporting activities. The use of a
four-strand plantaris tendon autograft in isolated anatomic medial patellofemoral ligament reconstructi on
can restore patellar stability in adolescents.
