Quicker strength recovery, but no outcome improvements with Minimally invasive TKA .
Minimally invasive total knee arthroplasty improves early knee strength but not functional performance: a randomized controlled trial
J Arthroplasty. 2012 Dec;27(10):1812-1819.e2. doi: 10.1016/j.arth.2012.02.016. Epub 2012 Mar 2844 patients were randomized to assess the effectiveness of minimally invasive surgical (MIS) TKA compared to a conventional technique over the early postoperative period. Patients awaiting a primary, unilateral knee arthroplasty for osteoarthritis received either MIS TKA (n = 22) or conventional TKA (n = 22). At four weeks, the MIS group showed better hamstring and quadriceps strength; however, there were no clinically meaningful differences between groups on any measure at 12 weeks.
