The '''intercondylar area''' is the separation between the [medial](/source/Medial_condyle_of_tibia) and [lateral condyle](/source/Lateral_condyle_of_tibia) on the [upper extremity](/source/Upper_extremity_of_tibia) of the [tibia](/source/tibia). The [anterior](/source/anterior_cruciate_ligament) and [posterior cruciate ligament](/source/posterior_cruciate_ligament)s and the [menisci](/source/meniscus_(anatomy)) attach to the intercondylar area.<ref name=GrayStudent>{{cite book |last1=Drake |first1=Richard L.  |last2=Vogl |first2=A.

The intercondyloid eminence is composed of the medial and lateral intercondylar tubercles, and divides the intercondylar area into an anterior and a posterior area.<ref name=GrayStudent/>

==Structure==

===Anterior area===
The '''anterior intercondylar area''' (or '''anterior intercondyloid fossa''') is an area on the [tibia](/source/tibia), a bone in the [lower leg](/source/lower_leg). Together with the [posterior intercondylar area](/source/posterior_intercondylar_area) it makes up the intercondylar area.<ref name=GrayStudent/>

The intercondylar area is the separation between the [medial](/source/Medial_condyle_of_tibia) and [lateral condyle](/source/Lateral_condyle_of_tibia) located toward the proximal portion of the tibia. The [intercondylar eminence](/source/intercondylar_eminence) composed of the [medial](/source/medial_intercondylar_tubercle) and [lateral intercondylar tubercle](/source/lateral_intercondylar_tubercle) divides the intercondylar area into anterior and [posterior part](/source/posterior_intercondylar_area).<ref name=GrayStudent/>

The anterior intercondylar area is the location where the [anterior cruciate ligament](/source/anterior_cruciate_ligament) attaches to the tibia.

===Intercondyloid eminence===
The '''intercondyloid eminence''', '''intercondylar eminence''' or '''tibial spine''' is a structure of the tibia. It lies between the articular facets of the proximal tibia, but nearer the posterior than the anterior aspect of the bone, surmounted on either side by a prominent tubercle, on to the sides of which the articular facets are prolonged. In front of and behind the intercondyloid eminence are rough depressions ([fossae](/source/fossa_(anatomy))) for the attachment of the [anterior](/source/anterior_cruciate_ligament) and [posterior cruciate ligament](/source/posterior_cruciate_ligament)s and the [menisci](/source/meniscus_(anatomy)).

Two [tubercle](/source/tubercle)s emerge from the eminence:
* The '''medial intercondylar tubercle''' is a protrusion on the medial condyle.
* The '''lateral intercondylar tubercle''' is a protrusion on the lateral condyle.

It can be involved in fractures.<ref name="pmid17310373">{{cite journal |vauthors=Park HJ, Urabe K, Naruse K, Aikawa J, Fujita M, Itoman M |title=Arthroscopic evaluation after surgical repair of intercondylar eminence fractures |journal=Arch Orthop Trauma Surg |volume=127 |issue=9 |pages=753–7 |date=November 2007 |pmid=17310373 |doi=10.1007/s00402-006-0282-7|s2cid=24350873 }}</ref><ref name="urlIntercondylar Eminence Fracture - Wheeless Textbook of Orthopaedics">{{cite web |url=http://www.wheelessonline.com/ortho/intercondylar_eminence_fracture |title=Intercondylar Eminence Fracture - Wheeless' Textbook of Orthopaedics |access-date=2008-12-04}}</ref>

===Posterior area===
Posteriorly, the medial condyle and lateral condyle are separated from each other by a shallow depression, the '''posterior intercondyloid fossa''' (or '''intercondylar area'''), which gives attachment to part of the posterior cruciate ligament of the [knee](/source/knee).
