The knee is proximal or superior to the metatarsals. It can't be described is medial or lateral to the metatarsals.
The first metatarsal bone is in direct contact with the medial cuneiform bone in the foot.
The tibialis anterior inserts into the medial cuneiform bone and the base of the first metatarsal bone in humans.
A structure on the inside of the knee will be medial compared to a structure on the outside. For example, the medial condyles of the knee are closer to the body's midline than the lateral condyles.
The semimembranosus and semitendinosus muscles attach on the medial (inner) side of the knee.
The tibial collateral ligament provides medial support for the knee. It's also called the medial collateral ligament.
The tibialis anterior muscle inserts onto the base of the first metatarsal and the medial cuneiform bone. It is responsible for dorsiflexion of the foot and inversion of the ankle.
Plural of metatarsal is metatarsus, they are the five long bones of the foot, and metacarpals are that of the hand
The three compartments of the knee are the medial compartment (inner side of the knee), lateral compartment (outer side of the knee), and the patellofemoral compartment (front of the knee where the kneecap articulates with the thigh bone).
Metatarsals are numbered starting at the medial side, which would make the big toe number 1.
Cruciate Lateral Medial
of the medial longitudinal arch, beneath the sustentaculum tali, and proximal to the first metatarsal head.
The medial collateral ligament (MCL) provides medial stability to the knee joint while the lateral collateral ligament (LCL) provides lateral stability.
