Reviewer 2 Report
From my point of view, the work is well-done and provides a biomechanical overview of the different effects corresponding to the several stem features that can be applied to provide stability in the femur and in the tibia during a revision TKA. The results demonstrated that anatomical shapes and slots are able to reduce bone stress and the risk of fracture, while flutes did the opposite. No relevant differences were found in this purview between cemented and press-fit stems. Cemented tibial stems have proven to reduce antero-posterior micromotions playing an important role in preventing implant loosening. This research can help clinicians to make evidence-based decisions for adequate fixation in revision total knee arthroplasty, determine the correct set-up for each patient and thus it merits to be published. Just, I suggest some minor language modifications before publication.
