Fig. 1From: Soft tissue stabilization of the hinge position in medial closed wedge distal femoral osteotomy: an anatomical studyDissection of the lateral aspect of the distal femur and insertion of ball bearings. a The attachment of the joint capsule to the distal femur was confirmed by tensioning with minimal force. b, c The margins of the inner and outer edges of the joint capsule and the lateral epicondyle were marked with colored nails. d Holes (2Â mm-diameter) were drilled into the marked cortical bone and 2Â mm-diameter radiopaque ball bearings were insertedBack to article page
