A joint prosthesis and/or trial implant alignment system () for intraoperatively assisting an alignment of a joint prosthesis and/or trial implant () during a surgical procedure is disclosed. The system comprises patient-specific pre-operative data () forming a three-dimensional image () containing bone structure () and a predetermined alignment of the joint prosthesis and/or trial implant () thereon. A patient imaging device () is for producing patient-specific intraoperative datawhich forms a two-dimensional imageshowing bone structure () and a real-time position of the joint prosthesis and/or trial implant () thereon. Registration means () registers the intraoperative datawith the pre-operative data () based on geometry of said bone structure and/or geometry of said joint prosthesis and/or trial implant (). A display device () for displaying an output of the registration means (), thereby enabling a visual indication of the said real-time alignment of the joint prosthesis and/or trial implant () relative to the said predetermined alignment.
