Is the LCL stronger than the MCL?
However, direct comparison across studies is difficult, as the range in reported strength and stiffness of the LCL is approximately 2-fold greater than that reported for the MCL. Thus, depending on the study, the LCL may be as much as 40% stronger or 40% weaker than the MCL.
Which is worse MCL or LCL tear?
While not always the case, an ACL tear is in most cases going to be the more severe injury. It is considered worse than tearing the MCL because ACL tears are in general more complex to treat and require a longer recovery time after surgery.

What is the MCL in the knee?
Another of the four main knee ligaments is the medial collateral ligament (MCL). This runs from the bottom of the femur, down the inside of the knee and over the joint to the top of the tibia. Like the ACL, it limits mobility of the knee joint and prevents it opening up too far when pressure is applied to the outside of the knee. Partial or complete tearing of the MCL ligament fibers is known as an MCL sprain. Although it can be injured in isolation, often the ACL is damaged at the same time. The most common cause of an MCL sprain is traumatic force applied to the outer side of the knee, and is an injury often sustained during the playing of contact sports. You can find a brace specifically designed for MCL injuries on this page.
What causes a sprain of the MCL?

Where is the ACL located?
The ACL runs from the bottom of the femur at the back of the knee, diagonally through the joint and attaches to the top of the tibia at the front of the knee. It provides stability to the joint by limiting the rotation and forward movement of the tibia underneath the femur. It is very strong but not very flexible.
Can a twisting motion tear the LCL?
Less commonly, a sudden, twisting motion can also tear the ligament. Athletes playing football, soccer or engaging in wrestling are more susceptible to LCL injuries. For an overview of all the braces available here at MMAR Medical for these types of knee injuries, click here.
Is the ACL flexible?
It is very strong but not very flexible. The ligament fibers can be torn by a sudden change of direction, a sudden transference of weight from one leg to the other, as when landing from a jump, a sudden stop, or by straightening the leg beyond the knee's normal range of motion. An injury of this kind is called an ACL tear.

How to protect knee ligaments?
Bracing. Your knee must be protected from the same sideways force that caused the injury. You may need to change your daily activities to avoid risky movements. Your doctor may recommend a brace to protect the injured ligament from stress. To further protect your knee, you may be given crutches to keep you from putting weight on your leg.
Where are the cruciate ligaments located?
These are found inside your knee joint. They cross each other to form an "X" with the anterior cruciate ligament in front and the posterior cruciate ligament in back. The cruciate ligaments control the back and forth motion of your knee.
Can a knee ligament be injured?

What is the role of the DMCL in knee rotation?
The dMCL helps stabilize internal rotation of the knee from full extension through 90-degree flexion (assists the knee in rotational stability primarily in extension moving through into early flexion).. Despite the relationship of the dMCL with the medial meniscus, there is no influence of the MCL on the stability of the medial meniscus.

Causes of an MCL sprain
An MCL sprain often happens when the knee joint is pushed beyond its normal range of motion. It's most common during a blow to the knee from the outside, pushing the knee inward. It may also happen if the knee is forced into a twist. These movements stretch and tear the MCL. Other parts of the knee may be damaged along with the MCL.
Treatment for an MCL sprain
Treatment will depend on the severity of the sprain and whether there is damage to other parts of the knee. Options often include:
