Tissue engineering has a fundamental role in regenerative medicine. Still today, the major motivation for cardiac regeneration is to design a platform that enables the complete tissue structure and physiological function ...
Combined femoral and tibial component total knee arthroplasty device rotation measurement is reliable and predicts clinical outcome
(2023-08-03)
Article.
Accés obert
Article.
Accés obert
Background The optimal total knee arthroplasty (TKA) rotational alignment and how best to obtain and measure it are debatable. The aim was to analyse the reliability of the Berger femoral, three different tibial and four ...
