PCL rupture tibial avulsion in a contact athlete teen with open physis. One case presentation and literature review

Abstract

Introduction: Given the infrequency and lack of consensus in the treatment of children and adolescents with theseinjuries, we decided to write this report with the aim of present a case of PCL tibial avulsion in a contact athlete teenwith open physis and a review of the literature published.Materials and Methods: RF.male, 13 years, rugby, suffers French tackle and fall on knees flexed. 3 months posttrauma consultation with left knee pain, joint fluid and sport limitation. Whidout instability but "not feeling well". Theposterior drawer test + +/++++, gravitational test +. Rx posterior drawer: 8mm difference between the two nenes.MRI: tibial avulsion PCL. We interpreted as symptomatic PCL injury in athletes, surgery (arthroscopy + posteriorapproach) is decided reintegration of chondral fragment in 1 time P.OP: no load 4 Weeks. plaster wedge extension6 weeks, then 3 months and passive immobilizer progressive mobility. Result(s): 0-90 mobility achieving in 8th week. The 3rd month drawer rx 4mm. MRI posterior translation of the 4thmonth reintegration of LCP with anchor. 6 month later minimally elongated drawer with stop net. 11th monthcontinuous strengthening recrearional and sports activities.Discussion and Conclusion(s): Most avulsion of PCL in patients with open physis probably be for greater strengthand endurance ligament compared with the phisis and bone at this age. We suspected in patients with vague kneepain, with or without instability, history of trauma and normal Rx a correct examination and MRI to be essential fordiagnosis. We beleave that athletes with open physis, because of the risk of joint degeneration, surgery is justifiedto restore kinematics, prevent osteoarthritis and resume activity prior to the injury.
