Randomized Controlled Trial Multicenter Study
Total Knee Arthroplasty Using Bicruciate-Stabilized or Posterior-Stabilized Knee Implants Provided Comparable Outcomes at 2 Years: A Prospective, Multicenter, Randomized, Controlled, Clinical Trial of Patient Outcomes.
The bicruciate-stabilized (BCS) knee arthroplasty was developed to replicate normal knee kinematics. We examined the hypothesis that patients with osteoarthritis requiring total knee arthroplasty (TKA) will have better functional outcome and satisfaction with the BCS implant compared with an established posterior cruciate-stabilized implant. ⋯ There was no evidence of clinical superiority of one implant over the other at 2 years.

Randomized Controlled Trial
Intra-articular Application is More Effective Than Intravenous Application of Tranexamic Acid in Total Knee Arthroplasty: A Prospective Randomized Controlled Trial.
The optimal administration route of tranexamic acid (TXA) in total knee arthroplasty (TKA), and the effect of TXA on hidden blood loss and total blood loss are undetermined. The purpose of this study was to compare the effectiveness of intravenous versus intra-articular application of tranexamic acid in patients undergoing knee arthroplasty. ⋯ Intra-articular administration of TXA significantly reduced total blood loss and drainage volume to a greater degree than IV injection in total knee arthroplasty without reduction of HBL.
