Implant survivorship for cementless TKA was comparable to the current gold st and ard cemented TKAs
Cementless  total knee arthroplasty ( TKA )  has had limited use in the United States , however , recent reports have demonstrated promising results , but there has been no meta- analysis to examine these outcomes in the past 5 years .
Prospective results of uncemented tantalum monoblock tibia in total knee arthroplasty: minimum 5-year follow-up in patients younger than 55 years.
A significant increase in younger patients undergoing total knee arthroplasty raises the theoretical concern for revision secondary to micromotion and fixation failure with cemented components . We prospect ively studied 100 consecutive tantalum monoblock uncemented tibial components and 312 concurrent cemented controls . Patients younger than 55 years with adequate bone stock were enrolled . This cementless patient group was younger and had higher preoperative functional status . Prostheses were posterior-substituting uncemented femoral and tibial components with a cemented patellar button .  Knee Society pain and function scores and radiographs were obtained , and a cost analysis was performed . Knee Society scores were excellent and equivalent beyond 6 months . There was no significant difference in perioperative blood loss , complication rates , or cost . There was a significant decrease in operative time in the uncemented group . Radiographs revealed no failures of ingrowth at last follow-up . There were 3 uncemented group failures , but none were due to failure of fixation . The use of a porous tantalum tibia at minimum 5 years has yielded promising clinical and radiographic results in a younger patient population
