Around the knee, the recommended distance between incision is 7 cm.99 Although there is no exact recommended distance for incisions around the hip, making long parallel incisions can disrupt the blood

preserve soft tissue on the lateral side, as the release of both the LCL and popliteus tendon is associated with a nearly 20 times increase in revision rates when using a CR knee. If the release of both LCL and popliteus is needed for balancing purposes, then

preservation of the posterior capsule and short external rotators, this approach may lead to decreased risk for posterior dislocation, as well as the possible benefit of early functional recovery.14-16 Supine patient positioning on a regular table or modified fracture table facilitates patient monitoring, assessment of component positioning
