Cartilage vs. Meniscus — What's the Difference?
By Fiza Rafique & Maham Liaqat — Published on August 26, 2024
Cartilage is a flexible connective tissue found throughout the body, while the meniscus is a specific type of cartilage in the knee joint aiding in cushioning and stability.

Key Differences
Cartilage serves as a flexible and resilient connective tissue found in various parts of the body, including joints, ears, and nose, providing support and cushioning. On the other hand, the meniscus is a specialized form of cartilage located specifically within the knee joint, playing a crucial role in absorbing shock and ensuring joint stability.
While cartilage can be of several types, including hyaline, elastic, and fibrocartilage, depending on its location and function, the meniscus is made of fibrocartilage, characterized by its unique C-shape and ability to withstand pressure and tension within the knee.
Cartilage is essential for the smooth operation of joints, reducing friction, and serving as a shock absorber in various parts of the body. In contrast, the meniscus not only reduces friction and absorbs shock in the knee but also contributes to the joint's nutritional supply and proprioceptive function.
Damage to cartilage can lead to conditions such as osteoarthritis, where the cartilage wears down over time, affecting many joints throughout the body. Meanwhile, meniscus injuries, often occurring from twisting or turning quickly, usually affect athletes or individuals engaging in physical activities, leading to knee pain, swelling, and limited movement.
In terms of treatment, cartilage damage can be addressed through methods such as physical therapy, injections, or surgery, depending on the severity and location of the damage. Meniscus tears may require rest, physical therapy, or surgical interventions like meniscectomy or meniscus repair, specifically tailored to the knee's needs.

Compare with Definitions
Cartilage
Includes hyaline, elastic, and fibrocartilage.
Elastic cartilage forms the structure of the ear, offering flexibility and shape retention.
Meniscus
Made of tough fibrocartilage to withstand pressure.
The meniscus absorbs shock during activities like running and jumping.
Cartilage
Provides support, cushioning, and reduces friction in joints.
Cartilage in the knee joint reduces friction between bones, enabling smooth movement.
Meniscus
A C-shaped piece of fibrocartilage located in the knee.
Each knee has two menisci, the medial and lateral, cushioning and stabilizing the joint.
Cartilage
A flexible connective tissue found in various parts of the body.
Hyaline cartilage covers the ends of bones in joints, providing a smooth, lubricated surface for movement.
Meniscus
Prone to tears from twisting motions or overuse.
A torn meniscus can cause knee pain, swelling, and difficulty bending the leg.
Cartilage
Subject to wear and tear, leading to osteoarthritis.
Degradation of joint cartilage over time can result in pain and reduced mobility.
Meniscus
Enhances knee stability, lubrication, and load distribution.
The meniscus ensures even weight distribution across the knee, preventing injury.
Cartilage
Ranges from conservative methods to surgical intervention.
In severe cases, damaged cartilage might require surgical repair or replacement.
Meniscus
Depends on the severity, including rest, therapy, or surgery.
Minor meniscus tears might heal with rest and physical therapy, while severe cases may require surgical repair.
Cartilage
A tough, elastic, fibrous connective tissue that is a major constituent of the embryonic and young vertebrate skeleton and in most species is converted largely to bone with maturation. It is found in various parts of the human body, such as the joints, outer ear, and larynx.
Meniscus
A crescent-shaped body.
Cartilage
A usually translucent and somewhat elastic, dense, nonvascular connective tissue found in various forms in the larynx and respiratory tract, in structures such as the external ear, and in the articulating surfaces of joints. It composes most of the skeleton of vertebrate embryos, being replaced by bone during ossification in the higher vertebrates.
Meniscus
The curved upper surface of a nonturbulent liquid in a container that is concave if the liquid adheres to the container walls and convex if it does not.
Cartilage
A particular structure made of cartilage.
Meniscus
A cartilage disk that acts as a cushion between the ends of bones that meet in a joint.
Cartilage
A translucent, elastic tissue; gristle.
Meniscus
(anatomy) Either of two parts of the human knee that provide structural integrity to the knee when it undergoes tension and torsion.
Cartilage
Tough elastic tissue; mostly converted to bone in adults
Meniscus
An interarticular synovial cartilage or membrane; esp., one of the intervertebral synovial disks in some parts of the vertebral column of birds.
Meniscus
A disk of cartilage that serves as a cushion between the ends of bones that meet at a point
Common Curiosities
Can cartilage repair itself?
Cartilage has limited self-repair ability, making injuries slow to heal or requiring medical intervention.
What is a meniscus?
A specific type of cartilage in the knee that cushions and stabilizes the joint.
How does the meniscus differ from other cartilage?
It's a specialized fibrocartilage in the knee, different in shape and function from other types.
Can you prevent cartilage damage?
Maintaining a healthy weight, regular exercise, and avoiding overuse can help protect cartilage.
What is cartilage?
A flexible connective tissue in various body parts, providing support and reducing friction.
What causes meniscus tears?
Often, sudden twists or turns, especially under weight, can tear the meniscus.
What are the symptoms of a meniscus tear?
Symptoms include knee pain, swelling, stiffness, and limited movement.
Is surgery always required for meniscus tears?
Not always; minor tears may heal with conservative treatments like rest and physical therapy.
Why is the meniscus important for knee function?
It's crucial for shock absorption, load distribution, and joint stability.
Can damaged cartilage regenerate?
Regeneration is limited; however, treatments can help relieve symptoms and improve function.
Are cartilage injuries common?
Yes, especially in athletes and older adults, due to wear and tear or physical activity.
How are meniscus injuries treated?
Treatment ranges from rest and physical therapy to surgical interventions like meniscectomy.
How do cartilage and meniscus contribute to joint health?
They reduce friction, absorb shock, and distribute loads to ensure smooth and stable joint movements.
What's the difference in treatment between cartilage and meniscus damage?
While some treatments overlap, meniscus-specific injuries often have tailored surgical options.
How does age affect cartilage and meniscus health?
With age, the risk of wear, tear, and injuries increases, leading to conditions like osteoarthritis and meniscus tears.
