intraoperative

Uncemented femur

Initial press fit

- implant geometry fits the cortical bone in the proximal femur

- good initial mechanical stability

Biological fixation for success

- good press fit

- minimal micromotion

- bony or fibrous tissue ingrowth or ongrowth

Reproduce the normal anatomical centre of rotation

Restore femoral offset

Maintain equal leg lengths

Usually template off normal hip

1. LLD

2. Offset

3. Femoral component

4. Acetabular component

5. Osteotomy / femoral seating
