Patent ID: 7780672

Claim:
A femoral adjustment device to balance a flexion gap, the device comprising: a body attachable to a distal femur, the body including a first elongated channel along a first axis; a frame movably coupled to the body, the frame including a first column member slidably received in the first channel and an elongated first cutting member substantially perpendicular to the first axis, the first cutting member including an elongated a first cutting guide substantially perpendicular to the first axis; and an adjustment mechanism operable to balance the flexion gap, wherein upon balancing the flexion gap, the first cutting guide is operable to guide at least one cut in the distal femur, the adjustment mechanism including: a linear adjustment mechanism operable to adjust a linear displacement of the cutting guide relative to the distal femur in a direction parallel to the first axis, the linear adjustment mechanism including a post substantially parallel to the first axis and a knob threadably connected to the post, the post coupled to the first cutting member such that rotating the knob incrementally moves the first cutting guide along the first axis relative to the body; and a rotational adjustment mechanism operable to adjust a rotational displacement of the first cutting guide relative to the body, wherein the rotational adjustment mechanism comprises a rotational member, the rotational member having first and second ends and a width tapering from the second end to the first end, the rotational member received in a recess of the body, the rotational member pivotably coupled to the body at a the first end about a second axis substantially perpendicular to the body and to the first cutting guide, the rotational member releasably coupled to the body at the second end for permitting relative rotation between the body and the rotational member.
