SUMMARY
Introduction
This study aimed to analyze the LPFM reconstruction in patients with open physis, with an ipsilateral autograft
from semitendinosus and to evaluate clinical and radiographic outcomes using the Caton-Deschamps index. Our hypothesis was
that the reconstruccion, besides getting patellar stabilization, generates a patellar descent with a good return to sports.
Methods
26 patients who were intervened by the same surgeon with the same technique were included. Lateral knee
preoperative and postoperative radiographs were measured, Caton Deschamps index was used by a doctor from the staff.
Tegner, Lysholm y IKDC Scales were used.
Results
The preoperative value of Caton-Deschamps index was 1.41 (±0.21), in postoperative it descended to 1.18 (±0.14).
Which shows a significant descent with a p-value of < 0.00014. On average an index decrease of 0.23 was accomplished after
surgery. 92.3% of the patients returned to the pre-injury sport level. Favorable functional outcomes (Tegner-Lysholm), in
relation to before surgery, p< 0.0001. IKDC 22 patients in the “normal” category (85%) 4 patients in the “close to normal”
category (15%).
Discussion
In this study we found the possibility to correct with only one procedure 2 factors influencing patellar instability,
stability and patellar descent through the medial femoropatellar ligament reconstruction. With improvement in functional
outcomes and good return to sport.
