outer part (Tuberculum intercondyloideuni inediale, laterale). On, before, and 

 behind the spine are the anterior and posterior intercondyloid fossae, in which 

 the anterior crucial Ugament and the semihniar cartilages are attached. The 

 condyles are separated behind by the deep popliteal notch (Incisura poplitea), on 

 the inner side of which is a tubercle for the attachment of the posterior crucial 

 ligament. The external condyle has an overhanging outer margin, below which is

a facet for articulation with the fil)ula. The large anterior eminence is the tu- 

 berosity of the tibia (Tuberositas tibiae). It is marked in front by a groove, the 

 lower part of which gives attachment to the middle patellar ligament, and the 

 groove is flanked by rough areas for the attachment of the internal and external 

 patellar ligaments. A semicircular smooth notch (Sulcus muscularis) separates the 

 tuberosity from the external condyle, and gives passage to the tendon of origin of 

 the anterior extensor and the peroneus tertius.
