All inside transtibial arthroscopic posterior cruciate ligament reconstruction in skeletally immature: Surgical technique and a case report

Abstract

Posterior cruciate ligament (PCL) tears are rare in children and may cause posterior instability of the knee. We present an original reconstruction technique. An 11-year-old boy sustained a PCL rupture. Despite initial immobilization followed by physiotherapy, he could not resume his previous sporting activities at the pre-injury level and complained of anterior knee pain. We performed an arthroscopic PCL reconstruction using a single bundle four-strand hamstring autograft. The femoral tunnel was drilled through the epiphysis and the tibial tunnel went through the physis under both arthroscopic and fluoroscopic control. The graft was secured using absorbable interference screws. At 2 years follow-up, the patient was asymptomatic and resumed sports at the same level as before the injury. Clinical examination was normal. There was no sign of growth disturbance. PCL injury is extremely rare in children. This original technique seemed appropriate in a symptomatic patient. IV.
