🔴 Meniscofemoral Ligaments 🔴

1️⃣ Femoral Bony Landmarks

  • The medial intercondylar ridge marks the superior border of the AL and PM bundle origins. 
  • The medial bifurcate ridge separates the two bundles. 

(J Knee Surg. 2021 Apr;34(5):499-508)

 

2️⃣ Femoral Attachment of the PCL

  • The ALB's center is located 7.4 mm from the trochlear point, 11.0 mm from the medial arch point, and 7.9 mm from the distal articular cartilage.
  •  The PMB femoral attachment center is 11.1 mm from the medial arch point and 10.8 mm from the posterior point of the articular cartilage margin. 
  • The PMB is bordered by the medial intercondylar ridge proximally, the ALB anteriorly, and the aMFL distally when present. 

(Am J Sports Med. 2015 Dec;43(12):3077-92)

 

3️⃣ PCL Complex

  • The PCL is functionally supported by the anterior (Humphrey) and posterior (Wrisberg) meniscofemoral ligaments and the posterolateral corner structures. 
  • The function of the MFLs is unclear but hypothesized to act as a secondary restraint, forming the PCL complex with the PCL. 

(Magn Reson Imaging Clin N Am. 2022 May;30(2):261-275; Semin Musculoskelet Radiol. 2016 Feb;20(1):43-51)

 

4️⃣ Meniscofemoral Ligaments (MFLs)

  • The anterior and posterior MFL can be observed in 20–75% and 70–100% of knees, respectively, with at least one MFL present in more than 90% of cases. 
  • On the femoral side, the MFLs attach just proximal (posterior MFL) and distal (anterior MFL) to the PMB's femoral attachment, exhibiting a circular cross-section. 

(Knee Surg Sports Traumatol Arthrosc. 2021 Mar;29(3):672-681)

 

5️⃣ Meniscofemoral Ligaments Details

  • The aMFL femoral attachment varies, with 80% of specimens attaching distally to the PMB and the remaining 20% to the ALB. 
  • The pMFL has a femoral attachment area of 31 mm², located proximal to the medial intercondylar ridge and PMB, and attaches distally to the posterior horn of the lateral meniscus.
