A ligament-tensioning device ( 1 ) for preparing the implantation of an articulated implant consists of a base body ( 5 ) comprising first claws ( 6, 6 ') provided with first bearing surfaces ( 7, 7 ') applied to a first bone part ( 33 ) and second claws ( 13, 13 ') provided with a second bearing surfaces ( 10, 10 ') applied to a second bone part ( 34 ). The claws ( 6, 6'; 13, 13 ') are displaceable with respect to each other with the aid of parallel-displacement devices ( 12, 12 '). In addition, the invention provides for a first scale ( 31 ) disposed on the base body ( 5 ) of the ligament-tensioning device ( 1 ) and second medial and lateral scales ( 32, 32 ') corresponding to the first scale ( 31 ), wherein the second scales ( 32, 32 ') are disposed on a guiding body ( 3 ) which is movably mounted with respect to said base body ( 5 ) by means of the parallel-displacement devices ( 12, 12 ). The scales ( 31, 32; 31, 32 ') can be brought into congruence in such a way that the height of an implant insertable into the treatable joint is separately medially and laterally presettable. |
