In brief: Instability.

Tears of either can make your knee feel unstable, but in different planes.
The MCL tear will give you more pain over the inner side of your knee.

In brief: Yes

Both are stabilizing ligaments in the knee.
The ACL (anterior criciate ligament) prevents the tibia (shin bone) from sliding forward from under the femur (thigh bone). The mcl (medial collateral ligament) prevents the knee from going into a medial or valgus ("knock-knee') postion. They can occur alone or in combination with each other.

In brief: MCL will heal

Mcl tears hurt on the inside of the knee when a stress is applied to the inside of the foot.
Acl tears cause instability in full extension and hurt when the knee shifts. Mcl tears usually heal in 2-3 months. Acl tears rarely heal.
