Posteromedial portal placed too far anteriorly

A common error is to place the posteromedial portal relatively far anteriorly in an effort to avoid the popliteal nerve and blood vessels. As a result the structures that project posteriorly (attachment of medial meniscus, medial tibial plateau, medial femoral condyle) tend to deflect the operating instruments towards the posterior capsule, thereby causing difficult in accessing the posterior horn of medial meniscus and PCL.
