Abstract
A knee distraction device is provided for facilitating knee arthroplasty. An adjustable force calibration mechanism is disposed in the device to accommodate controlled selection of the ligament-tensioning force to be applied at respective opposite sides of the knee. In preferred embodiments, the tensioning force is provided by a screw-threaded connection with a calibrated compression spring interposed between the tensioning members. According to another preferred embodiment, fluid pressure is applied by means of a calibrated pressure valve to apply the ligament-tensioning force.
