Come error and puzzlement, so that can not accurately estimate articular cartilage thickness when guide plate design, to influence the accuracy of osteotomy, separately has
Though part guide plate can estimate cartilage thickness, removal cartilage will increase operating time and can not accurately consolidate in actual mechanical process
Position, and there is the unbalanced, knee joint tibial of development for condyle of femur in 3D printing personalization knee osteotomy guide plates all at present
Femur old fracture malunion and larger bony defect cannot complete whole osteotomy processes, and existing guide plate is not examined
Considering knee joint peripheral soft tissue balance and bending and stretching gap is rectangle；In addition inlet guide is expensive, and production and transport takes a long time,
Therefore, it is necessary to improve to existing guide plate.
The production method of knee osteotomy guide plate common at present mainly extracts lower limb skeletons, knee according to CT, MRI data
After articular surface cartilage, after determining the biomethanics marks such as lower limb mechanical axis, the line of force, logical condyle axis, incisura intercondyloidea, set in conjunction with required
The knee-joint prosthesis data changed carry out CAD design, determine Osteotomy and femur outward turning angle, and the guide groove of guide plate is exactly real
Border need Osteotomy, cannot arbitrarily change, and the configuration of guide plate be not it is constant, no matter how it changes
All always around " accurate in place fixed, guide plate guide groove and design are consistent to improve osteotomy precision ".
