Das derzeitige Ziel der Knieendoprothetik ist die Verbesserung der Patientenzufriedenheit
nach operativer Versorgung mittels einer Totalendoprothese. Dabei werden verschiedene
Ansätze
verfolgt. Eines dieser Konzepte ist die Versorgung mittels alternativer Alignmentstrategien.
Das in den vergangenen Jahren meistdiskutierte Prinzip ist das sog. kinematische Alignment.
Dieser Fortbildungsartikel soll die Grundprinzipien sowie die Versorgungsmöglichkeiten
praktisch erläutern.
Abstract
Nowadays, kinematic alignment is a widely used alignment philosophy in total knee
arthroplasty. The concept of kinematic alignment respects the patient’s individual
prearthrotic anatomy and
is based on the reconstruction of the femoral anatomy and thus the axes of motion
of the knee joint. Only then the alignment of the tibial component is adapted to the
femoral component. By
means of this technique soft tissue balancing is reduced to a minimum. Due to the
risk of excessive outlier alignment technical assistance or calipered techniques are
recommended for precise
implementation. This article attempts to provide an understanding of the fundamentals
of kinematic alignment, and it focusses on how it differs from alternative alignment
strategies and the
way the philosophy is implemented in different surgical techniques.
