Fig. 1B —STAR arthroplasty device (Scandinavian Total Ankle Replacement, Waldemar Link) is cementless, three-component (mobile-bearing) design developed by H. Kofoed in 1981. Mobile, ultrahigh-molecular-weight polyethylene (UHMWPE) meniscus (thick black arrow) articulates superiorly with trapezoidal, flat, cobalt–chromium tibial plate (white arrow) and inferiorly with longitudinally ridged, convex, cobalt–chromium talar component (thin black arrow). Talar component possesses fin (asterisk, B) that inserts caudally into talus. Two characteristic cylindric bars (arrowheads) positioned on superior aspect of tibial component serve to anchor implant in subchondral tibia. Anteroposterior radiograph of STAR arthroplasty device.
