was changed:
The meniscofemoral ligament (MFL) arises from the posterior horn of the lateral meniscus and passes to attach to the lateral aspect of the medial femoral condyle. It splits into two bands at the posterior cruciate ligament (PCL), which are named named in relation to the PCL:
- anterior
meniscofemoralmeniscofemoral ligament (ligament of Humphrey) - posterior
meniscofemoralmeniscofemoral ligament (ligament of Wrisberg)
A handy mnemonic to recall the relationship is is here.
Variant anatomy
The MFL is variably described as either possessing one band (~35%) or as described above, possessing two bands (~65%) 3.
Approximately 80% (range 65%-100%) of people will have at least one MFL with the posterior MFL (50-70%) more commonly present than the anterior MFL (10%-25%). 20-30% of people will have both anterior and posterior MFLs 2.
