Title (EN) MODULAR KNEE PROSTHESIS
(FR) PROTHÈSE MODULAIRE DU GENOU
Abstract:
(EN) The present invention relates to a modular knee prosthesis assembly kit (10) for replacement of resected articular surfaces of a distal femur of a first patient side. The kit (10) comprises (a) at least one bi-condylar component (20) sized and shaped to substantially replace resected posterior and distal condylar bone portions; and (b) at least a first trochlear groove component (50) and a second trochlear groove component (70), each sized and shaped to replace a resected trochlear groove bone portion. The first trochlear groove component (50) comprises a first patella articulation path defining a first trochlear groove direction angle. The second trochlear groove component (70) comprises a second patella articulation path defining a second trochlear groove direction angle. An assembly of the bi-condylar component (20) and one of the first and second trochlear groove components (50; 70) forms a substantially complete femoral knee prosthesis. The second trochlear groove direction angle is different from the first trochlear groove direction angle.
(FR) La présente invention concerne un kit d'assemblage de prothèse modulaire du genou (10) destiné au remplacement de surfaces articulaires réséquées d'un fémur distal d'un premier côté d'un patient. Le kit (10) comprend (a) au moins un élément bi-condylien (20) dimensionné et formé pour remplacer sensiblement les parties osseuses condyliennes postérieures et distales réséquées ; et (b) au moins un premier élément de rainure trochléaire (50) et un second élément de rainure trochléaire (70), chacun dimensionné et formé pour remplacer une partie osseuse à rainure trochléaire réséquée. Le premier élément de rainure trochléaire (50) comprend un premier trajet d'articulation de rotule définissant un premier angle de direction de rainure trochléaire. Le second élément de rainure trochléaire (70) comprend un second trajet d'articulation de rotule définissant un second angle de direction de rainure trochléaire. Un assemblage de l'élément bicondylien (20) et de l'un des premier et second éléments de rainure trochléaire (50 ; 70) forme une prothèse de genou fémorale sensiblement complète. Le second angle de direction de rainure trochléaire est différent du premier angle de direction de rainure trochléaire.
