The intercondylar area of the tibial plateau is located in the middle of the articular surfaces of the medial and lateral condyles. It is narrow centrally where it is raised in order to create the intercondylar eminence, the sides of which are elevated further in order to create medial and lateral intercondylar tubercles. The intercondylar region bears six distinct facets for the attachment of menisci as well as cruciate ligaments.
The anterior intercondylar area widens anteriorly and bears three facets:
- The most anterior facet is for attachment of the anterior end of the medial meniscus.
- Immediately posterior towards the most anterior facet is a facet for the attachment of the anterior cruciate ligament.
- A small facet for the attachment of the anterior end of the lateral meniscus is located just lateral towards the site of attachment of the anterior cruciate ligament.
Anterior Intercondylar Area
The posterior intercondylar area also bears three attachment facets:
- The most anterior facet is for attachment of the posterior horn of the lateral meniscus.
- Posteromedial towards the most anterior facet is the site of attachment for the posterior horn of the medial meniscus.
- Behind the site of attachment for the posterior horn of the medial meniscus is a large facet for the attachment of the posterior cruciate ligament.
Posterior Intercondylar Area
A large anterolateral area of the anterior intercondylar area is roughened as well as pierced by numerous small nutrient foramina for blood vessels, along with these six sites of attachment for menisci and cruciate ligaments. This region is located against infrapatellar connective tissue and is continuous with a similar surface on the front of the tibia above the tuberosity.
