Authors reviewed 159 cases of total hip arthroplasty which had used uncemented femoral components associated with Harris-Galante uncemented metal backed acetabular component and followed more than 1 year at least to identify overall incidence of osteolysis, incidence of osteolysis according to type of implant, time of first noted, radiographic distribution of osteolysis with its shape and size and correlation between osteolysis and relevant factors. The results were followings: 1) Overall incidence of femoral endosteal osteolysis in the use of three kind of uncemented femoral components associated with Harris Galente, uncemedted metal backed acetabular component was 6.3% 2) Osteolysis was first noted radiographically at 12 to 55 months(mean, 27months) postoperatively. 3) In most patients, osteolysis occurred at Zone 2, 3,5, 6 on AP radiograph and Zone 3,5,6 on lateral radiograph, where was distal to porous pad. 4) Mean liner wear rate in patient with osteolysis was 0.46 mm/year, which was higher than that reported previously and mean wear rate in cases with progression of osteolysis was higher than that without progression of osteolysis. 5) No correlation could be found between thickeness of polyethylene liner and osteolysis.
