Conclusion Based on the small number of studies with appropriate statistical analysis , we are unable to reach a clear conclusion in the clinical performance of medial stabilized knee replacement construct .
Background Medial stabilized  total knee joint replacement ( TKJR ) construct is design ed to closely replicate the kinematics of the knee .
Little is known regarding comparison of clinical functional outcomes of patients utilising vali date d patient reported outcome measures ( PROM ) after medial stabilized TKJR and other construct design s. Purpose To perform a systematic review of the available literature related to the assessment of clinical functional outcomes following a  TKJR  employing a medial stabilized construct design .
A mid-term clinical outcome study of the Advance Medial Pivot knee arthroplasty.
The Advance Medial Pivot Total Knee Arthroplasty ( Wright Medical Technology , Arlington , Tennessee , USA ) has been design ed to reproduce modern ideas of knee kinematics . We report a prospect i ve clinical outcome study of 284 arthroplasties in 225 consecutive patients with a mean follow-up of 6.7 years ( range 4 to 9 years ) . For evaluation , both  objective and subjective clinical rating systems  and serial radiographs were used . At final follow-up , 10 ( 4.4 % ) patients ( 10 knees ) only were lost from follow-up and four ( 1.8 % ) patients ( five knees ) had died for reasons unrelated to the surgery with their knees performing well . There was an 82 % compliance in the intervals of follow-up evaluation . All patients showed a statistically significant improvement ( p=0.01 ) in the Knee Society clinical rating system , WOMAC question naire , SF-12 question naire , and Oxford knee score . The majority of patients ( 92 % ) were able to perform age-appropriate activities with a mean knee flexion of 117 degrees ( range 85 degrees to 135 degrees ) at final follow-up . Survival analysis showed a cumulative success rate of 99.1 % at 5 years . Two ( 0.7 % ) arthoplasties , in which patient selection and surgical errors were identified , were revised due to aseptic loosening , one due to infection and one due to a traumatic dislocation . This study demonstrates satisfactory mid-term clinical results for this knee design
