Dr. Incavo and colleagues recently published their findings from the research study, Postoperative Alignment in Revision Total Knee Arthroplasty, a Comparison between Intra and Extramedullary Tibial Alignment, in The Knee.
The aim of this study was to compare an intra-medullary (IM) and extra-medullary (EM) alignment method. The authors hypothesized that IM technique and canal-filling stems may result more frequently in valgus mechanical alignment (MA), while an EM technique could produce less valgus knees though at risk of creating MA outliers.
