Increasingly young and active patients are concerned about revision arthroplasty forcing the manufacturers to think about revision prostheses that fit to this population while meeting the indications and fitting with bone losses and ligament deficiencies. One of those industrials claims that its system allows the surgeon to rise the constraint from a posterior stabilized (PS) prostheses to a semi-constraint total stabilized (TS) prostheses without modifying the gait pattern thanks to a similar single radius design. The aim of the study was to compare gait parameters in patients receiving either PS or TS knee prostheses. Nineteen patients in each groups were prospectively collected for this study and compared between each other. All subjects were assessed with a 3D knee kinematics analysis, performed with an optoelectronic knee assessment device (KneeKG®). Were measured for each knees range of motion (ROM) in flexion–extension, abduction–adduction, internal–external rotation and anterior–posterior displacement.Introduction
