Anterolateral approach to the proximal tibia

1. Skin incision

A prior midline skin incision can be considered for a deep anterolateral approach for the tibia. Consideration should be given to the amount of soft tissue retraction required to attain adequate visualization and stabilization of the fracture.

Skin incision

If the sentinel incision is too medial, then a minimally invasive incision can be considered in a more lateral position. The risk of skin complication is reduced when the periprosthetic fracture is remote in time from the original knee arthroplasty.

2. Opening the fascia

Open the deep fascia anterior to the iliotibial tract.

Release the proximal attachment of the tibialis anterior muscle. If necessary, release the iliotibial tract by incising it or taking a small flake of bone from Gerdy’s tubercle.

 
Opening the fascia

Dissect the tibialis anterior muscle from the bone without stripping the periosteum.

Retract the tibialis anterior muscle laterally.

Caution: Do not attempt to expose the posteromedial side of the tibia from the anterolateral approach. This will risk injury to the extensor mechanism and create a challenging healing environment for the skin.

3. Wound closure

Before closure, irrigate the knee joint to remove any debris. Standard layered closure is performed. The use of a suction drain may be considered. Close the skin with staples or nonabsorbable sutures.
