Figure 1

It is showing a dot plot of cup position. Patients with low inclination and low anteversion angles but high elevated Co and Cr values are indicated by the red and orange arrows. The implant positions of the patient with bilateral THA with low inclination and low anteversion angles but normal metal ion concentrations are indicated by the blue and green arrows.
