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 .
Blood loss after minimally invasive total knee arthroplasty: effects of imageless navigation.
A prospect i ve cohort study of 100 patients undergoing primary minimally invasive total knee arthroplasty was carried out to determine blood loss after this procedure and to examine the efficacy of navigation on blood saving . The patients were divided into two groups according to the surgical technique , and underwent either computer-assisted navigation or manual procedures . All operations were performed by a single surgeon using an identical approach . To minimize blood loss , an intraoperative tourniquet was used , but no postoperative drainage was applied . Although the mean surgical time was longer in the navigated group than in the manual group ( 119.2 vs. 90.9 min ; p < 0.001 ) , the reductions in hemoglobin level ( 1.40 vs. 1.38 g/dL ; p = 0.642 ) and calculated blood loss ( 470.77 vs. 482.73 mL ; p = 0.796 ) were similar in both groups . Four patients in both groups required blood transfusion . With minimally invasive techniques and drainage avoidance , our study suggests that the blood loss after minimally invasive total knee arthroplasty was not significantly affected by the use of imageless navigation
