Meniscal Horn Attachments¶
This section describes the anterior and posterior attachemnts of the medial and lateral menisci to the tibia.
General Description¶
The medial and lateral meniscus both have anterior and posterior attachment sites on the tibial plateau.

Lateral Meniscus¶
- Anterior insertion (alHorn): area of 140.7 mm^2 (+/- 30.0). The center of the attachment is approximately 7.1 mm (+/- 1.3) from the nearest edge of the lateral articular cartilage, and 13.4 mm (+/- 2.1) from the nearest edge of the posterior lateral meniscus attachment. [LER+14]
- Posterior insertion (plHorn): area of 39.2 mm^2 (+/- 2.4). The center of the attachment is approximately 12.7 mm (+/- 1.1) from the nearest point on the PCL tibial insertion, and 10.1 mm (+/- 0.8) from the posterior edge of the anterior root attachment of lateral meniscus [JCP+12].
Medial Meniscus¶
The anterior insertion of the medial meniscus (amHorn) is described as having a central dense root, and supplemental fiber extensions [LER+14]. The model will only include the central dense root of the attachment.
- Anterior insertion (amHorn): area of 56.3 mm^2 (+/- 14.9). The center of the attachment is approximately 7.6 mm (+/- 2.3) from the nearest edge of the medial articular cartilage, and 9.2 mm (+/- 2.7) from the nearest edge of the ACL insertion. [LER+14]
- Posterior insertion (pmHorn): area of 30.4 mm^2 (+/- 2.9). The center of the attachment is approximately 8.2 mm (+/- 0.7) anterior of the most superior tibial attachment of the PCL, and 3.4 mm (+/- 0.4) lateral to the medial articular edge inflection point. [JCP+12]
