Using the Anatomical Axis as an Alternative to the Mechanical Axis to Assess Knee Alignment.
The treatment of knee osteoarthritis and the preparation for total knee arthroplasty require repetitive imaging to guide preoperative planning and operative technique. Full-length standing anteroposterior images are the gold standard in assessing the alignment of the limb via the measurement of the mechanical axis of the knee. The anatomical axis can be obtained from a more limited image of the...
متن کاملPredicting the Feasibility of Correcting Mechanical Axis in Large Varus Deformities With Unicompartmental Knee Arthroplasty.
BACKGROUND Due to disappointing historical outcomes of unicompartmental knee arthroplasty (UKA), Kozinn and Scott proposed strict selection criteria, including preoperative varus alignment of ≤15°, to improve the outcomes of UKA. No studies to date, however, have assessed the feasibility of correcting large preoperative varus deformities with UKA surgery. The study goals were therefore to (1) a...
متن کاملA simple technique to aid intraoperative identification of the tibial mechanical axis during total knee replacement
BACKGROUND Successful total knee replacement (TKR) requires accurate component placement and coronal plane malalignment of greater than 3o varus/valgus from the mechanical axis has been shown to predispose to early failure.1–3 An extramedullary alignment jig is most commonly used to identify the mechanical axis. The distal end of the jig should be centred over the ankle mortise, which can be di...
متن کاملVarus-valgus Alignment in the Progression of Knee Oa
Introduction. Most of the epidemiologic literature concerning OA deals with risk factors for the initial development of arthritis. However, in a large subset of people, knee OA remains a relatively mild condition. The form of knee OA responsible for the bulk of individual and societal cost is OA that progresses beyond mild stages. Identification of factors responsible for progression is critica...
متن کاملAlignment Analyses in the Varus Osteoarthritic Knee Using Computer Navigation.
Osteoarthritic (OA) knees with severe extension varus deformity seem to have correspondingly more severe flexion varus, especially beyond a certain tibiofemoral angle. Clinical measurement of flexion varus and fixed flexion deformity (FFD), which had been difficult to perform because of the spatial alignment of the knee in flexion, was recently made possible with computer navigation. We conduct...
