Is a minimally invasive approach superior to a conventional approach for total knee arthroplasty? Early outcome and 2- to 4-year follow-up

摘要

Total knee arthroplasty (TKA) has been widely applied as an effective treatment for knee arthritis for several decades. More recently, minimally invasive surgery (MIS) has been developed for TKA. The purpose of this study was to clarify the difference in clinical results between MIS and conventional TKA. We hypothesized that knee function would recover earlier with MIS than with conventional TKA without major problems, and hence the middle-term outcome would be better with MIS TKA.
