Yang CP, et al. - A retrospective trial was conducted to assess the effectiveness and longevity of the mini-keel modular tibial implant in minimally invasive surgery (MIS) total knee arthroplasty (TKA). Experts also drew a comparison between cruciate-retaining (CR) and posterior-stabilized (PS) designs. Good reliability and results with both CR and PS prostheses in minimally invasive surgery TKA were demonstrated by the modular mini-keel tibial components.
