This retrospective cohort study distinguished between the clinical outcomes of total knee arthroplasty (TKA) via the mini-midvastus (MMV) method or the medial parapatellar (MPP) method. Also, the method leading to improved quality of life after surgery was also examined.
In this study of 330 patients who underwent total knee
arthroplasty, TKA, better QOL can be acquired by performing TKA via a
mini-midvastus, MMV approach while overlooking the artificial joint following
TKA is the definitive target. One of the utmost benefits of TKA through the MMV
method is that it maintains the extensor mechanism as much as possible during
the surgery thereby easing perioperative pain and earlier recovery.
This retrospective cohort study distinguished
between the clinical outcomes of total knee arthroplasty (TKA) via the
mini-midvastus (MMV) method or the medial parapatellar (MPP) method. Also, the
method leading to improved quality of life after surgery was also examined.
This study was executed in a total of 330 patients who
underwent TKA using a mini-midvastus (MMV) method. For comparison, 330 patients
who underwent TKA using a medial parapatellar (MPP) method (MPP group) were
also considered. Pain (via visual analogue scale score), range of motion (ROM),
and Knee Society Score were examined. The ability to forget the joint was
analyzed via the Forgotten Joint Score.
Noteworthy differences concerning visual analogue scale score, ROM, and the Knee Society Score until 6 months following surgery between MMV and MPP groups were observed (Table 1).
Nonetheless, the differences were not noteworthy at 1, 2, and 3 years postoperatively. During the follow-up, significant differences in the Forgotten Joint Score amongst the groups were found (Table 2).
Improved quality of life can be attained by the execution of TKA via the MMV method. Additionally, the MMV method can provide less pain and a quicker recovery compared with MPP.
