Miller AJ, et al. - This study was implemented to assess the clinical and radiographic outcomes of cementless total knee arthroplasty (TKA) using a novel highly porous cementless tibial baseplate. According to findings, cementless TKA using a highly porous tibial baseplate designed with a keel and four pegs appeared to afford promising early outcomes. At minimum 2-year follow up, 1 case of aseptic loosening was reported. Data indicated that the use of a highly porous cementless tibial baseplate may be beneficial in providing long-term durable biologic fixation similar to the success of cementless THA as the demographics of patients undergoing TKA change to include younger, obese, and more active patients, along with increased life expectancy.
