Posterior cruciate ligament and posterolateral corner reconstruction in patient with multiple ligament injury of the knee: a case report

摘要

The treatment of posterolateral corner (PLC) knee injuries has always been a challenging topic due to the low healing capacity of PLC injuries. Authors performed posterior cruciate ligament reconstruction using semitendinosus tendon graft and reconstruction procedure of PLC using free gracilis tendon graft with LaPrade technique in a patient with multiple ligament injury of the knee. A 36-years-old male patient complained of pain on his right knee. On physical examination, the posterior drawer test, dial test, and varus stress test were positive. Magnetic resonance imaging (MRI) on right knee showed that the posterior cruciate ligament (PCL), lateral collateral ligament, and popliteofibular ligament were injured but the popliteus tendon was still intact. A semitendinosus tendon was harvested from the ipsilateral pes anserinus region for posterior cruciate ligament reconstruction. Posterolateral corner reconstruction was done by grafting two gracilis tendons from ipsilateral and contralateral sides using LaPrade technique. The semitendinosus tendon graft had been used for PCL reconstruction in some cases besides the hamstring tendon graft and provides a clinically evident reduction in symptoms and restores satisfactory stability. The LaPrade technique for PLC reconstruction was one of the earliest descriptions of a surgical option to recreate the anatomy of the three main static stabilizers of the PLC. We reported a reconstructive procedure for PCL and PLC injury of the knee by using semitendinosus and gracilis tendon graft with LaPrade technique.
