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 .
Does Minimally Invasive Total Knee Arthroplasty Improve Isokinetic Torque?
Background Less invasive dissection of the extensor apparatus , one of the aspects of minimally invasive surgical ( MIS ) TKA , might result in less reduction of postoperative quadriceps strength . However , it is unclear whether MIS is associated with less strength reduction . Questions / purpose sWe asked whether knee strength ( extensor or flexor torque ) would be greater in patients having a MIS TKA  compared with patients having a st and ard TKA  and whether knee scores , alignment , ROM , tourniquet and operating times , and hospital length of stay were improved . Methods We prospect ively recruited 52 patients awaiting MIS or st and ard TKA , matched for age , weight , height , BMI , sex , and surgically treated side , but not r and omized .  Isokinetic tests  were performed preoperatively and postoperatively to obtain peak values of extensor and flexor torque . Postoperative-to-preoperative ratios and the extensor-flexor torque ratio also were calculated . Results Mean baseline extensor torques were 57 Nm and 53 Nm for MIS and st and ard TKAs , respectively . At 8 weeks postoperatively , absolute values of the mean postoperative knee extensor torque also were similar : 47 and 45 Nm for patients with MIS and st and ard TKAs , respectively . The postoperative-to-preoperative ratios were 0.8 for extensor and flexor torque in both groups . The extensor-flexor torque ratios were similar between groups . Conclusions Our data suggest a less invasive dissection of the extensor apparatus involved in MIS TKA does not enhance postoperative quadriceps strength .
