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 .
Minimally Invasive Subvastus Approach: Improving the Results of Total Knee Arthroplasty: A Prospective, Randomized Trial
Background Minimally invasive knee arthroplasty seeks to diminish the problems of traditional extensile exposures aim ing for more rapid rehabilitation of patients after surgery . Questions / purpose s To determine if the subvastus approach results in less perioperative pain and blood loss , shorter hospital stay , and improved function at both early and long-term followup . Methods One hundred patients were enrolled in a prospect i ve , r and omized trial . Fifty were operated on using a minimally invasive subvastus approach and the other 50 by a conventional , peripatellar approach .  Minimum followup was 3 years . A repeated- measures analysis of variance was used to compare the Knee Society score and range of motion during followup . Results The minimally invasive approach result ed in greater perioperative bleeding but no increase in transfusions . No differences were found in postoperative pain between groups nor did hospital stay show any differences . The range of motion on the third day after surgery was greater in the minimally invasive group . No differences were found in surgical time , femoral or tibial component orientation or outliers , or complication rates . Both Knee Society score and range of motion were superior using the minimally invasive subvastus approach during followup out to 36 months . Conclusions The minimally invasive subvastus approach can result in improved long-term Knee Society scores and range of motion of total knee arthroplasty without increased risk of component malalignment , surgical time , or complication rate .
