Should we aim at undercorrection when doing a total knee arthroplasty?
This study showed that conventional TKA instruments are associated with a systematic unintentional bias towards undercorrection of the pre-existing deformity. The clinical relevance of this study is that intentionally aiming at slight undercorrection of the deformity may lead to excessive undercorrection in reality in case the surgeon does not recognise the automatic bias that already exists with standard instruments.
Low tuberculosis notification in this mountainous setting is probably a true reflection of low tuberculosis incidence. Possible causes for low incidence in mountainous areas include low transmission rates or altitude-related differences in pathology.
