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 .

Minimally Invasive Computer-Assisted Total Knee Arthroplasty Compared With Conventional Total Knee Arthroplasty: A Prospective 9-Year Follow-Up.
BACKGROUND Studies on minimally invasive computer-assisted total knee arthroplasty ( MICA-TKA ) have shown promising results , but are limited by short follow-up . The purpose of this study was to compare the midterm radiographic features and functional outcomes between patients who underwent MICA-TKA and conventional TKA .  METHODS A total of 108 patients who were r and omized to undergo MICA-TKA or conventional TKA during 2004 and 2005 were contacted for a prospect i ve follow-up review . Patients who were lost to contact , have passed away , or declined to participate in the study were excluded . Objective functional measurements and radiographs were obtained for assessment . RESULTS By the time of this study , 2 patients from the conventional group had undergone revision TKA , one due to infection and one due to aseptic loosening . A total of 67 patients ( 62.04 % ) were followed up for an average period of 9.07 years ( 8.51 - 9.61 years ) . At follow-up , functional scores were comparable between the 2 groups . No significant intergroup differences were found in mechanical knee alignment and component placement angle in the coronal views . No statistical or clinical significance were noticed in radiographic signs of component loosening . CONCLUSIONS MICA-TKA provided similar clinical , functional , and radiographic outcomes compared with conventional TKA after an average of 9-year follow-up . This technique can be used to exploit its short-term advantages without compromising midterm outcomes
