Patient selection for cementless knee arthroplasty (TKA) remains challenging. 106 consecutive TKAs performed with a cementless porous tantalum tibial component of PS-design were reviewed. Nine failures (8 male/1 female) occurred at a mean 18 months and demonstrated a characteristic failure mode of medial tibial collapse. The mean height of 72.5 inches in the failure group was greater than the 65.8 inches in the well-functioning group (P<0.001). The mean weight of 260.4 lb in the failure group… CONTINUE READING
