Orthopaedic fixator with adaptable kinematics for functional treatment of periarticular fractures of the knee joint – experimental research, computer simulation, first clinical trial

An orthopaedic stabiliser to be used for the treatment of periarticular fractures of the knee joint is presented. The design of the device is documented by experimental research of the knee joint kinematics. Experimental and simulation research suggests the use of a four-bar linkage mechanism. This research has also made it possible to define the range of adjustment to adapt the kinematics of the stabiliser to the individual characteristics of patients. This paper presents the results of the first trials for clinical stabiliser.
