Patellar Tendon Rupture After Anterior Cruciate Ligament Surgery

Adolescent Quadriceps Tendon Rupture, an Early Complication After ACL Reconstruction: A Case Report

CASE

A healthy adolescent male patient initially presented with complete rupture of the anterior cruciate ligament (ACL) after a plant-twist injury during a high school football game. Four weeks after ACL reconstruction with autograft bone-patella tendon-bone, the patient slipped and fell, sustaining hyperflexion of the knee, resulting in rupture of the ipsilateral quadriceps tendon.

CONCLUSION

Although this rare complication has previously been reported in the adult population, to the best of our knowledge, this is the first known report of an adolescent patient sustaining a quadriceps tendon rupture after ACL reconstruction.

Reconstruction of patellar tendon rupture after anterior cruciate ligament reconstruction: a case report

Patellar tendon rupture following use of its central third for anterior cruciate ligament (ACL) reconstruction is a rare disabling injury that is technically difficult to repair. We report one case of patellar tendon rupture after harvesting the mid-third for ACL reconstruction. A number of different surgical methods exist for reconstructing patellar tendon ruptures. Here we report a case using a bone-tendon-bone (BTB) allograft, followed by a multiple-wire loop reinforcement with no postoperative immobilisation. One year after operation, our patient had regained full knee extension and flexion. Insall Salvati index on the operated side was identical to the uninjured side. The patient had good quadriceps strength, and isokinetic muscle testing showed no deficit in his right leg. He was able to return to professional handball without limitation.
