A retractor assembly has a first clamp adapted to be mounted to a table, a first vertically oriented post supported by the clamp, a first main arm mounted for at least one of angular and lateral movement relative to the first post, and lockable in a selected position, and a tree assembly configured at one end of the second post. The tree assembly has at least two accessory arms, with each accessory arm having a first ball joint on a first end, and a pivot lock knob at an immediate portion, and each accessory arm having a second end configured to accept the mounting of a retractor to the accessory arm. The retractor assembly may also include a J-shaped hook mounted to a ratcheting linearly movable distractor assembly and trochanteric retractors mounted to the accessory arms for femoral elevation and exposure.
