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 .
Faster recovery after minimally invasive surgery in total knee arthroplasty
Purpose The aim of the study was to identify whether less soft tissue and muscle damage during surgery will allow faster recovery after total knee arthroplasty in comparison with the conventional technique . A limited medial parapatellar approach without tibial medial collateral ligament ( MCL ) desinsertion was compared with the conventional parapatellar approach . Methods Three hundred patients were r and omized either into the minimally invasive group ( MIS group ) or into the conventional group ( CON group ) . The evaluation was based on the Knee Society Score , range of motion , blood loss , period of hospitalization and postoperative hemoglobin level . Results The MIS group showed faster recovery with immediate postoperative full weight-bearing and shorter length of stay ( 5 vs 10 days ) . Comparable Knee Society Scores ( 87.5 vs 88 ) , function scores ( 90 ) and alignment ( 5.5 ° vs 5.2 ° ) between the CON and MIS group were observed at a follow-up of 24 months . No increase in operative times ( 52 vs 51 min tourniquet time ) or no complications were observed . Reduced blood loss was observed in the MIS group ( 590 vs 989 ml ) . Conclusion The MCL sparing limited medial parapatellar approach allows good surgical exposure , easy extension proximally if necessary , contained closure after surgery with less bleeding , faster recovery , full weight-bearing without aid and most importantly no radiological malalignment . Level of evidence Therapeutic study , Level II
