An intraoperative leg stabilizing system has a platform with a slidable
brace received in a longitudinal groove. The slidable brace supports the
patient's foot. The platform also has an outrigger that pivots about a
base in the platform. The outrigger can pivot up to a desired
orientation. The longitudinal position of the slidable brace and the
orientation of the outrigger can be fixed through locking mechanisms. The
system includes a support belt that can be wrapped around the patient's
thigh and then connected to the outrigger. The combination of components
allows the patient's leg to be stabilized in a desired position and
degree of flexion during knee arthroplasty, and to be easily released
when desired for evaluation of the patient's leg in extension.
