Make sure to avoid the neurovascular structures around the knee (common peroneal nerve, deep peroneal nerve, and popliteal artery).
Make a straight incision lateral to the patella. Then, open the deep fascia anterior to the ilio-tibial tract.
Identify Gerdy’s tubercle. Make a straight incision about 5cm in length starting posteriorly to Gerdy’s tubercle and running distally and anteriorly.
With the knee in slight flexion make a straight or slightly curved incision running from the medial epicondyle towards the posteromedial edge of the tibia.
The posteromedial side can be approached without exposing and dissecting the neurovascular structures.
