Event Description

This file is a review of the following journal article: alonso, b., et al (2016) pretibial pseudocyst after anterior cruciate ligament reconstruction with a biocomposite screw.Acta ortopedica mexicana, vol.30, pages 150-153.(spain).The study emphasizes on the case of a patient who presented a pretibial extra-articular cyst two years after an arthroscopically assisted acl reconstruction using an autologous bone-patellar tendon-bone graft.Tibial fixation was achieved with a bioabsorbable screw made of poly-l, d-lactic and tricalcium phosphate (tcp).A subcutaneous pseudocystic lesion was excised.It consisted of a capsular fibrous tissue with minimal milky fluid (1 ml), centrally located.It penetrated the tibial tunnel but did not communicate with the knee joint space.The histopathological analysis demonstrated fibrous tissue with multinucleated giant cells and refractile particles which suggested a foreign body reaction.After the surgery, the patient recovered perfectly well, and he returned to his pre-injury level of physical activity in two months.To the best of our knowledge, this is the first report of this complication in a patient with a biocomposite screw made of poly-l, d-lactic and tricalcium phosphate (tcp).The patients evaluated on course of this study: (b)(6) year-old male.The article describes the following procedure: acl.The devices involved were: rigidfix.
