The concept of minimally invasive total knee arthroplasty surgery evolved to
reduce quadriceps muscle strength loss and improve clinical outcome following
total knee replacement.
We performed a systematic review of the published
literature on Minimally Invasive Total Knee Arthroplasty (MITKA) and analyzed the
reported surgical outcomes. Twenty-eight studies published from January 2003 to
June 2008 that met the inclusion criteria were evaluated using the modified
Coleman Methodology Score (CMS). At a mean CMS of 60, most studies reporting on
outcome of MITKA are of moderate scientific quality. Patients undergoing MITKA
tend to have decreased postoperative pain, rapid recovery of quadriceps function,
reduced blood loss, improved range of motion (mostly reported as a short-term
gain) and shorter hospital stay compared with patients undergoing standard total
knee arthroplasty. These benefits, however, need to be balanced against the
incidence of increased tourniquet time and increased incidence of component
malalignment in the MITKA group. So far, the evidence based knowledge regarding
results of MITKA comes from prospective studies of moderate quality with short
follow up periods. Multicenter studies with longer follow-ups are needed to
justify the long-term advantages of MITKA over standard total knee arthroplasty.
