Abstract
Introduction:
Given the infrequency and lack of consensus in the treatment of children and adolescents with these injuries, we decided to write this report with the aim of present a case of PCL tibial avulsion in a contact athlete teen with 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 post-trauma consultation with left knee pain, joint fluid and sport limitation. Whidout instability but "not feeling well". The posterior 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 + posterior approach) is decided reintegration of chondral fragment in 1 time P.OP: no load 4 Weeks . plaster wedge extension 6 weeks, then 3 months and passive immobilizer progressive mobility.
Results:
0-90 mobility achieving in 8th week. The 3rd month drawer rx 4mm. MRI posterior translation of the 4th month reintegration of LCP with anchor . 6ª month later minimally elongated drawer with stop net. 11th month continuous strengthening recrearional and sports activities.
Discussion and Conclusion:
Most avulsion of PCL in patients with open physis probably be for greater strength and endurance ligament compared with the phisis and bone at this age. We suspected in patients with vague knee pain, with or without instability, history of trauma and normal Rx a correct examination and MRI to be essential for diagnosis. We beleave that athletes with open physis, because of the risk of joint degeneration, surgery is justified to restore kinematics, prevent osteoarthritis and resume activity prior to the injury.
