• Research summary

  The purpose of this study is to evaluate how far a knee can bend and stretch (maximum flexion) after knee replacement surgery using one of three different high flexion knee implants, the Maxx Freedom Total Knee® System (Maxx Medical Pvt. Ltd) the P.F.C® Sigma® CR150 High Flex Knee System (DePuy, Orthopaedics, Inc) and the NexGen® Complete Knee Solution CR-Flex Fixed Bearing Knee (Zimmer, Inc). \n\nSome patients require greater flexion from their knee implants after surgery, especially young patients, active patients or patients who generally need to have as much flexion as possible in order to continue working or for daily living. This study compares the three knee implants (already approved for use in the UK)in order to establish which knee implant allows the maximum amount of flexion 12 months after a total knee replacement. \n
