Abstract

The present invention pertains to the field of medical devices, and in particular relates to a biological patellar groove replacement assembly and an operation method. The biological patellar groove replacement assembly includes a prosthesis, a trial implant and a base block. The trial implant has an upper surface generally coinciding and height consistent with those of the prosthesis and can be used to simulate a mounting orientation of the prosthesis. Tuning holes in the trial implant can be used to preliminarily position the trial implant and facilitate tuning of its orientation. Drilling shafts can be inserted into locating holes in the trial implant and first and second locating holes in the base block and then used to drill first and second mounting holes in an osteotomy surface of a femur, enabling accurate positioning of the base block and the prosthesis. In this way, a positional match between the mounting holes in the osteotomy surface of the femur and mounting pegs on the prosthesis can be ensured, which in turn better ensures that the prosthesis can be mounted at an orientation determined by the trial implant, effectively improving the success of a procedure for implanting the prosthesis.
