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 .

Patellar Tracking and Anterior Knee Pain are Similar After Medial Parapatellar and Midvastus Approaches in Minimally Invasive TKA
Background Since the medial parapatellar ( MPP ) approach in conventional TKA can cause patellar maltracking and anterior knee pain , some orthopaedic surgeons use the midvastus ( MV ) approach instead of the MPP approach to reduce patellar maltracking . Minimally invasive surgical ( MIS ) TKA has been developed to limit the damage to the surrounding muscle and reduce the necessity of patellar eversion during surgery . Thus , MIS TKA might be associated with proper patellar tracking and a low incidence of anterior knee pain . However , this presumption has not been confirmed . Questions / purpose sWe asked whether the incidence of patellar maltracking and anterior knee pain differed with the MV and MPP in association with MIS TKA . Methods We prospect ively followed 59 patients ( 60 knees ) treated with 60 primary cemented MIS TKAs from August 2009 to September 2010 . We r and omized the patients into two groups : 30 who had a limited MPP approach and 30 who had a mini-MV approach . We recorded the occurrence of anterior knee pain , patellar tilting , and subluxation . The minimum followup was 12 months ( mean , 18.03 months ; range , 12.00–25.08 months ) . Results We found no differences in anterior knee pain ( two of 30 , 7 % versus two of 30 , 7 % ) , mean patellar tilt ( 3.4º ± 2.9º versus 3.0 ± 2.3º ) , and mean patellar subluxation ( 1.5 ± 1.1 mm versus 1.1 ± 0.7 mm ) between the limited MPP and mini-MV groups , respectively . Conclusions MIS TKA using either the MPP or MV approach has a low incidence of patellar maltracking and anterior knee pain . Level of Evidence Level I , therapeutic study .
