Reconstruction of Anterior Cruciate Ligaments

摘要

Apparatus for locating an attachment position for a reconstructed anterior cruciate ligament on an attachment surface of a bone comprises locating means 51, 61 arranged to locate at least one reference surface 4 of the bone and guide means 53, 54 arranged to define the attachment position in two dimensions on the attachment surface relative to the reference surface.

主权项

1. An instrument set that includes two or more instruments for locating an attachment position for a reconstructed anterior cruciate ligament (ACL) in a respective femur, each instrument of the instrument set comprising:
a handle; a side piece comprising:
a first surface shaped to fit at least in part against a lateral side wall of an intercondylar notch to locate the instrument relative to the respective femur, anda second surface configured to contact a roof of the intercondylar notch at the same time the first surface is at least in part against the lateral side wall of the intercondylar notch to locate the instrument relative to the respective femur; and a tip arranged to wrap around a back surface of a condyle of the respective femur and contact the back surface of the condyle at the same time the first surface is at least in part against the lateral side wall of the intercondylar notch and the second surface is contacting the roof of the intercondylar notch to locate the instrument relative to the respective femur; wherein some of the two or more instruments are different from one another based on a size of the respective femur to which the instrument is designed to be applied, wherein the instrument differences include different spatial relationships among the first surface, the second surface, and the tip of respective instruments defined by accumulation of anatomical measurement data from a statistically significant number of femurs such that a locating characteristic defines the attachment position for the reconstructed ACL.
