Abstract
To compare the effectiveness of computer-assisted
surgery (CAS) and mechanical jig technique in hip
resurfacing arthroplasty, we reviewed 176 hip
resurfacing arthroplasty performed in 158 patients. The
initial 131 hips were resurfaced using the conventional
mechanical jig technique, and the remaining 45 hips with
the CAS technique. The demographic data of the patients
were similar for both techniques. Follow-up radiographs
taken 2 months after the surgery showed patients in the
CAS technique having a significantly better alignment of
the femoral component on the frontal and sagittal
planes. There was no difference in the risk of implant
notching on the femoral neck for both techniques. The
implant sizes were similar for both techniques; thus,
the amount of bone stock preserved was not technique
specific.
