A method of preparing a biomedical implant comprises preparing an implant having a first roughened surface exhibiting a first R a value between about 0.1 µm and about 100 µm. The first roughened surface of the implant is exposed to a treatment formulation to form a second roughened surface exhibiting a second R a value being substantially similar to the first R a value. The second roughened surface of the implant exhibits enhanced cement/implant mechanical interlocking upon contact with cement. The first roughened surface can be formed using a process such as blasting, grinding, spraying, cast moulding, and mechanical deformation. The second roughened surface can be formed using a process such as acid etching.
