INTERPRETATION There was a clinical ly relevant association between early migration of TKPs and late revision for loosening .
PURPOSE We performed two parallel systematic review s and meta-analyses to determine the association between early migration of tibial components and late aseptic revision .
The Outcome of the Cementless Tibial Component: A Minimum 14-Year Clinical Evaluation
The long term survival of the Miller-Galante I cementless total knee arthroplasty  was evaluated by study ing prospect ively for a minimum of 14 years ( range , 14–17 years ) , 124 consecutive cementless total knee arthroplasties using a Miller-Galante I prosthesis in 99 patients with a mean age of 62 years who had primary or secondary osteoarthritis .  Knee function and roentgenograms were evaluated using the Knee Society criteria . Kaplan-Meier survivorship analysis was conducted . Five patients ( five knees ) were lost to followup ; six patients died with six knees in place . Fifteen knees ( 15 patients ) failed and were revised . Thirteen metal-backed patellas were revised . Eight of these revisions also required exchange of the femoral component , but only one tibial tray was revised . One knee ( one patient ) was revised for an infection . Of the 98 knees not revised ( 73 patients ) observed throughout this study , the average preoperative knee score was 31 ( range , 0–47 ) ; postoperatively , the average knee score was 91 ( range , 72–100 ) . The average function score improved from 28 ( range , 10–45 ) to 84 ( range , 50–100 ) . Twenty-four tibial trays ( 21 % ) and twenty femoral components ( 17 % ) of the 113 knees studied showed osteolysis . This study indicates that osteointegration of cementless tibial components can be successful with screw fixation , although there is a worrisome incidence of tibial and femoral osteolysis . The overall knee survival rate was 87 % ; however , the tibial component had a survival of 99 %
