Abstract
PCL lesions are generally well tolerated but they almost always make part of a multiligament lesion.
First it is very important to rule out neurovascular lesions and also check soft-tissue trauma.
For the diagnosis, besides physical examination, we order x-rays and MRIs.
In acute cases a conservative treatment should always be indicated for PCL and MCL because they have healing power.
Concerning grafts, in combined lesions for PCL reconstruction, we prefer autografts in patients below 35 years. For the other reconstructions we prefer soft tissue allografts, for instance an anterior tibial tendon.
We perform the PCL femoral anatomic tunnel inside out and a transtibial tunnel in tibia. We try to reconstruct the PCL AL band.
Regarding Medial or Posteromedial instability we prefer to reconstruct the sMCL and the POL. In cases when the patient has no posteromedial instability we only perform the sMCL.
When we repair posterolateral corners we always add an LCL and PFL reconstruction.
If the patient has a posterolateral and rotational instability we reconstruct the popliteus tendon.
In this kind of lesions we indicate immobilization and crutches for 6–8 weeks.
