The MSV approach ranked better concerning clinical scores ( the lowest visual analogic scale , the higher KSS and KSFS ) and functional outcomes ( the shortest straight leg raise , the greatest degree of flexion and range of motion ) .
Concerning perioperative data , the MSV evidence d the shortest hospital stay , while the MPP the shortest surgical duration and lowest estimated blood loss .
According to the main findings of the present study , the mini-subvastus approach for total knee arthroplasty demonstrated superior overall compared to the other approaches .
Alternatives to the classical medial parapatellar ( MPP ) approach for total knee arthroplasty ( TKA ) include the mini-medial parapatellar ( MMPP ) , mini-subvastus ( MSV ) , mini-midvastus ( MMV ) and quadriceps-sparing ( QS ) approaches .
The best approach has been not fully clarified .
The purpose of the present study was to conduct a Bayesian network meta- analysis comparing these approaches .
Total knee replacement performed with either a mini-midvastus or a standard approach: a prospective randomised clinical and radiological trial.
We report the clinical and radiological results of a two- to three-year prospect i ve r and omised study which was design ed to compare a minimally-invasive technique with a st and ard technique in  total knee replacement  and was undertaken between January 2004 and May 2007 . The  mini-midvastus approach was used on 50 patients ( group A ) and a st and ard approach on 50 patients ( group B ) . The mean follow-up in both groups was 23 months ( 24 to 35 ) . The functional outcome was better in group A up to nine months after operation , as shown by statistically significant differences in the mean function score , mean total score and the mean Oxford knee score ( all , p = 0.05 ) . Patients in group A had statistically significant greater early flexion ( p = 0.04 ) and reached their greatest mean knee flexion of 126.5 degrees ( 95 degrees to 135 degrees ) 21 days after operation . However , at final follow-up there was no significant difference in the mean maximum flexion between the groups ( p = 0.08 ) . Technical errors were identified in six patients from group A ( 12 % ) on radiological evaluation . Based on these results , the authors currently use minimally-invasive techniques in total knee replacement in selected cases only
