Modification of the Hybrid Anatomic Technique for Anterior Cruciate Ligament Reconstruction in Pediatric Patients.

The incidence of anterior cruciate ligament (ACL) lesions with Tanner stage ≤4 has been increasing in children. To stabilize the knee, different surgical techniques have been developed for ACL reconstruction in the pediatric population. The use of a hybrid anatomic technique, intra-epiphyseal in the femur and transphysis in the tibia, has been recommended as the technique of choice to reconstruct the ACL in these patients. Despite the favorable results, this technique is not exempt from complications. The aim of this study was to present a simple and reproducible modification of the hybrid anatomic technique for ACL reconstruction in pediatric patients.

Patellar Tendon Lengthening: Rescue Procedure for Patella Baja.

Patella baja is a challenging pathologic condition that causes pain and functional restrictions and can even lead to premature osteoarthritis-even more so in cases of patella infera or cases associated with degeneration of the patellar tendon in which simple conservative treatment frequently is not resolutive. Several surgical options have been described for symptomatic patella baja: excision of the lower third of the patella, lengthening of the patellar tendon, reconstruction of the patellar tendon with allograft, and proximalization of the tibial tubercle. A combination of 2 or more of these treatments may be recommended in cases of significant patella baja. We present a simple and reproducible technique to address patella baja that combines a partial transposition of the tibial tubercle and patellar tendon lengthening using a subperiosteal patellar flap in continuity with the patellar tendon.
