Ligament Basics - Science Explained
Summary
TLDRThis video script delves into the anatomy of ligaments, emphasizing their role in the musculoskeletal system and their distinction from tendons. It highlights the knee joint, illustrating the four major stabilizing ligaments: ACL, PCL, MCL, and LCL. The script cautions against overstretching these elastic collagen fibers and discusses the challenges of healing torn ligaments, unlike broken bones. It advises seeking medical help from orthopedic doctors and engaging in physical therapy for rehabilitation, promoting a quick return to normal activities.
Takeaways
- 𦴠Ligaments are round structures that connect bones and are part of the musculoskeletal system.
- π Tendons and ligaments are often confused, but tendons attach muscle to bone, while ligaments attach bone to bone.
- 𦡠Joints, such as the knee, have multiple ligaments that stabilize and limit bone movement.
- ποΈββοΈ The knee has four major stabilizing ligaments: ACL, PCL, MCL, and LCL.
- β οΈ Torn ligaments do not heal like broken bones; they cannot simply reattach themselves.
- 𧬠Ligaments are made of collagen fibers and are slightly elastic, allowing them to stretch and increase flexibility.
- π Overstretching ligaments can compromise joint stability, so caution is needed when stretching.
- π§ββοΈ The term 'double-jointed' refers to people with highly elastic ligaments, allowing for more extreme joint positions.
- π¨ββοΈ If you injure a ligament, it's best to consult an orthopedic doctor for diagnosis and treatment.
- πββοΈ Working with a doctor and physical therapist is crucial for proper rehabilitation and recovery from ligament injuries.
Q & A
What is the function of ligaments in the human body?
-Ligaments function to hold bones together by connecting bone to bone, stabilizing joints, and limiting their movement.
How are tendons different from ligaments?
-Tendons attach muscle to bone, whereas ligaments connect bone to bone.
What are the major ligaments that stabilize the knee joint?
-The four major stabilizing ligaments of the knee are the ACL (anterior cruciate ligament), PCL (posterior cruciate ligament), MCL (medial collateral ligament), and LCL (lateral collateral ligament).
What is the consequence of overstretching a ligament?
-Overstretching a ligament can compromise the integrity of the joint it stabilizes, leading to instability and potential injury.
Can torn ligaments heal naturally like broken bones?
-No, torn ligaments do not reattach and heal naturally like broken bones. They require specialized medical intervention, such as rehabilitation or surgery.
What is the composition of ligaments?
-Ligaments are primarily composed of long stringy collagen fibers, forming tough fibrous connective tissue. They have slight elasticity, allowing them to stretch within limits.
Why are people with 'double-jointed' ability more flexible?
-People who are 'double-jointed' have highly elastic ligaments, which allow them to move their joints into more extreme positions than most people.
What should someone do if they injure a ligament?
-If someone injures a ligament, they should consult an orthopedic doctor, who can diagnose the injury and recommend a suitable physical therapy or rehabilitation plan.
How can someone strengthen their ligaments after an injury?
-Working with a doctor and physical therapist to develop a rehabilitation routine is key to strengthening ligaments after an injury. Stretching, but not overstretching, is also important for recovery.
What does the term 'musculoskeletal system' refer to?
-The musculoskeletal system is the combination of muscles, bones, tendons, and ligaments that work together to support the body and enable movement.

𦴠Understanding Ligaments and Tendons
This paragraph explains the role of ligaments in the musculoskeletal system, contrasting them with tendons. Ligaments are round structures that hold bones together, while tendons attach muscles to bones. The paragraph uses the knee as an example to illustrate the function of ligaments, mentioning the ACL, PCL, MCL, and LCL as major stabilizing ligaments. It also discusses the elasticity of ligaments, the concept of being 'double-jointed', and the importance of caution when stretching to avoid overstretching and joint instability. The paragraph concludes with advice on seeking medical help for ligament injuries and the process of rehabilitation.

Highlights
Ligaments are round structures that hold bones together, forming part of the musculoskeletal system.
Tendons and ligaments are often confused, but tendons attach muscle to bone while ligaments attach bone to bone.
Joints contain various ligaments that stabilize and limit the movement of bones, such as the femur, tibia, fibula, and patella in the knee.
The ACL, PCL, MCL, and LCL are the four major stabilizing ligaments in the knee.
Injuries to ligaments, such as a sprained ankle, are common and can be debilitating.
Ligaments are primarily composed of collagen fibers, creating tough fibrous connective tissue.
Ligaments have a slight elasticity, allowing for stretching and increased flexibility, but can be overstretched and damaged.
The term 'double-jointed' refers to individuals with highly elastic ligaments, enabling extreme joint positions.
Injured ligaments require medical attention, as they do not heal like broken bones.
Orthopaedic doctors are skilled at diagnosing ligament injuries and can guide rehabilitation.
Physical therapy is crucial for recovering from ligament injuries and regaining mobility.

look at my face very simply ligaments
are round to hold our bones together
it's all part of this thing we like to
call the musculoskeletal system now
people sometimes confuse tendons with
ligaments and while they have some
similarities tendons attach muscle to
bone and ligaments attach bone to bone
now if you look at any joint you'll find
a whole array of ligaments functioning
to stabilize and limit the movement of
the bones within take the knee for
instance you have the femur here and
then the tibia and fibula on top of that
you have your kneecap or patella
now remember ligaments connect bone to
bone and in the knee let's show these
four major stabilizing ligaments this is
your ACL here's your PCL here is the MCL
and here's the LCL now if you've ever
tweaked your knee ligaments or any other
ligament your body say sprained an ankle
then you'll probably want to know what
you can do to strengthen and heal them
unfortunately for us torn ligaments are
not like broken bones they won't just
reattach themselves and heal here's the
basics ligaments are composed mostly of
long stringy collagen fibers that create
bands of tough fibrous connective tissue
ligaments themselves are slightly
elastic so they can be stretched and
gradually lengthen increasing
flexibility but if stretched beyond a
certain point ligaments can become over
stretched and compromise the integrity
of the joint they're supposed to be
stabilizing so stretch with caution and
as a little tidbit the term
double-jointed actually refers to people
who have highly elastic ligaments which
allow them to move their joints into
more extreme positions than most people
now if you did injure a ligament you
might as well go to the doctor trained
orthopaedic Doc's are usually the best
at diagnosing these injuries work with
them and the physical therapy staff to
find a rehab routine that suits your
needs and you're doing that to get back
on top of things as quickly as possible
thanks for watching this video was done
in tandem with this ACL video that we
did with dr. Pat Connor from ortho
Carolina who happens to also be the head
doc for the Carolina Panthers check that
