There was no significant difference in the outliers on complications , knee flexion , and postoperative functional scores .
Coronal plane tibial component showed statistically significant number of outliers in the MIS group demonstrating superior component positioning in the MIS CA group .
Computer-assisted minimally invasive TKA is superior than the st and ard MIS TKA in terms of component positioning ; however , it is unclear if this will have any long-term clinical implication s. The increased operative time , although clinical ly relevant , does not appear to be associated with an increase in complications
BACKGROUND Median parapatellar approach is the most used for total knee arthroplasty ( TKA ) .
With the advent of enhanced recovery and shorter length of hospital stay , there is an increasing pressure on surgeons to perform surgery through smaller incisions .
Minimally invasive ( MIS ) TKA allows earlier functional recovery ; it is not clear if this is associated with more complications .
It is also unclear if computer-assisted minimally invasive ( MIS CA ) TKA has any affect on improving patient outcomes .
We performed a systematic review and meta- analysis comparing MIS CA vs MIS TKA .
Comparative study between computer assisted-navigation and conventional technique in minimally invasive surgery total knee arthroplasty, prospective control study.
BACKGROUND Both Minimally Invasive surgery ( MIS ) and Computer-Assisted Surgery ( CAS ) are useful in Total Knee Arthroplasty ( TKA ) . Minimally invasive total knee arthroplasty was associated with decreased blood loss , shorter hospital stays , and increased range of motion .  Computer-assisted surgery in total knee arthroplasty was developed to improve the positioning of implants during surgery . OBJECTIVE To evaluate radiographic results relative to component position and limb alignment when using a navigation system compared with conventional technique in MIS-TKA . MATERIAL AND METHOD A prospect i ve control study was performed in 180 patients who underwent total knee arthroplasty by one surgeon . All patients were r and omly divided into two groups , Conventional and Navigation TKA .  Intra- , post-operative data , and postoperative limb alignment were recorded for comparison in both groups . RESULTS The postoperative mechanical axis was within 3 degrees of neutral mechanical alignment in 94 % of the navigation group and 87 % in conventional group ( p = 0.13 ) . Registration time of navigation group is 13.58 minutes . No statistical significant difference was found in tourniquet time and postoperative blood loss in both groups . CONCLUSION The use of navigation in total knee arthroplasty increases accuracy in limb and implants alignment , and does not increase complications and surgical times
