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 .
Mini-incision versus mini-incision and computer-assisted surgery in total knee replacement: a radiological prospective randomised study.
The aim of this trial was to compare the radiological results of 74 patients undergoing a mini-invasive total knee replacement ( TKR ) using either a traditional alignment guide ( MIS group ) or a computer assisted alignment system ( MICA group ) . All the patients were prospect ively r and omised to either group and the same implant was used for both groups . At 8 months post-operatively , the frontal femoral component angle ( FFC ) , the frontal tibial component angle ( FTC ) , the hip-knee-ankle angle ( HKA ) and the sagittal orientation of components ( slopes ) were evaluated respectively . The slopes of the femoral component and the FTC angle were statistically better aligned in the MICA group ( p<0.001 ) . The MICA group showed both a significant fewer number of outliners and a significant higher number of implants with all five radiological parameters ideally aligned . The operative time was statistically longer in the computer assisted group
