THA with MoM bearings in 2006 (Figure 2).
Lauenstein view of the right hip immediately after surgery (a) and at 2 (b), 4 (c), 6 (d), 8 (e), and 10 (f) years after surgery. After 4 years, acetabular osteolysis developed in zones 1 and 2 (black arrow heads), and the lesion was most significant at 6 years after surgery. However, most of the osteolytic area had been replaced by newly formed bone at 10 years (white arrow heads) without evidence of implant loosening.

THA, major acetabular osteolysis developed in his right hip in Delee and Charnley zones 1 and 2 (Figure 3(c)), whereas no osteolytic change was observed in the left side. The osteolytic change was most significant at 6 years after surgery (Figure 3(d)). Finally, most of the osteolytic area had been replaced by newly formed bone at 10 years (Figure 3(f)).
