Femoral socket creation. A left knee is viewed from the left side. The fibular collateral ligament (FCL) socket is created using a 7-mm reamer, up to a depth of 25 mm, at a point 1.4 mm proximal and 3.1 mm distal to the lateral epicondyle. Similarly, a 7 × 25–mm socket is created for the popliteus tendon (PT) insertion at the proximal fifth of the popliteus sulcus. There must be an adequate bone bridge between the 2 sockets, and the distance between their centers is about 18.5 mm.
