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 .
Long-term results of Kinematic Condylar knee replacement. An analysis of 404 knees.
We present the long-term results of the  Kinematic Condylar Knee Arthroplasty  followed in a prospect i ve fashion . Between October 1982 and March 1988 , 404 consecutive replacement arthroplasties were carried out on 335 patients . Of these , 354 knees had osteoarthritis , 45 rheumatoid arthritis and five other diagnoses . At the time of final follow-up 158 patients ( 188 knees ) had died . No patient was lost to follow-up . The minimum follow-up for all living patients was ten years ( 10 to 17 ) . The mean age at surgery was 68 years ( 30 to 92 ) . There were seven complications ( 1.7 % ) . Sixteen knees ( 3.9 % ) were revised , four because of infection . Survivorship was 99.4 % ( CI 97.9 to 99.8 ) at five years , 98.2 % ( CI 96.1 to 99.2 ) at ten years and 92.6 % ( CI 87.6 to 95.6 ) at 17 years
