A device which is adapted to be mounted on the edge of an operating table for holding a patient's thigh or upper leg in a fixed position on the table while arthroscopic surgery is being performed on the patient's knee. An inflatable member is secured on a first curved metal retention plate which is mounted on a flat metal portion of an angled base plate. The inflatable member is wrapped about the thigh of the patient and is secured thereon by fastening means. A second curved metal retention plate is adjustably mounted on the flat portion of the angled base plate opposite of the first retention plate. This second plate is moved into an adjusted position against the inflatable member diametrically opposite of the first retention plate to securely hold the patient's thigh and inflatable member between the pair of curved retention plates. Each retention plate provides an arcuate clamping surface slightly greater than the quadrant of an imaginary circle which is defined by the contours of the inner surfaces of the retention plates and patient's thigh. The inflatable member then is inflated, which securely grips the patient's thigh simultaneously with the inflatable member being securely clamped between the retention plates by its outward expansion. A downwardly projecting leg portion of the angled base plate then is inserted into a usual bracket mounted along the edge of an operating table to securely hold the thigh immobilized in the desired position on the table.
