A Randomized Trial Of Ceramic-On-Ceramic Bearing Versus Ceramic-On-Crossfire-Polyethylene Bearing In Total Hip Arthroplasty: Five-Year Outcomes

This study determined how ceramic-on-ceramic bearing THA affected joint-specific pain, function and stiffness in the first five postoperative years compared with ceramic-on-highly-crosslinked-polyethylene bearing THA. Subjects less than 61 years of age were randomized to ceramic-on-ceramic (CERAMIC)...

Summary:This study determined how ceramic-on-ceramic bearing THA affected joint-specific pain, function and stiffness in the first five postoperative years compared with ceramic-on-highly-crosslinked-polyethylene bearing THA. Subjects less than 61 years of age were randomized to ceramic-on-ceramic (CERAMIC) [n = 48] or ceramic-on-highly-crosslinked-polyethylene (POLYETHYLENE) [n = 44] bearing THA. Subjects were assessed using the Western Ontario McMaster Osteoarthritis Index (WOMAC) and the RAND 12-Item Health Survey (RAND-12) preoperatively, and at one and five years postoperatively. 92 subjects(50 (54%) males; average age = 52 (SD 6.6) years) were enrolled. 78 (85%) subjects returned five years postoperatively. All subjects reported improvements at one and five years in all measured indices with no group differences detected. Seven (8%) subjects experienced postoperative THA complications, none related to bearing surfaces; two subjects (POLYETHYLENE) required revision for instability. Both bearing surfaces provided excellent short-term results in younger subjects.
