Editorial “Mid-term results of the BIOLOX delta ceramic-on-ceramic total hip arthroplasty”

Historically, ceramic-on-ceramic (COC) articulations in total hip arthroplasty (THA) have been shown to have the lowest rate of wear and osteolysis (1). However, the use of COC bearings has been lessened by their risk of fracture, squeaking and revision surgery (2-4). As a result, in 2003, Ceramtec (Plochingen, Germany), the largest manufacturer of ceramic bearings in the world, introduced their 4th generation of ceramic components—Biolox Delta.
