A Guide to Understanding How Tendons Work & Why It Matters
Every movement you make, big or small, depends on healthy tendons. From getting out of bed in the morning to playing sports or lifting groceries, tendons work behind the scenes to keep your body moving. Tendons play a key role in how your bones and muscles work together smoothly and efficiently.
At Iowa Specialty Orthopedics, we believe that understanding your body is the first step toward staying active and pain-free.

Tendon Basics
A tendon is a strong, flexible band of tissue that connects muscle to bone.
When your muscles tighten (contract), your tendons pull on your bones. This pulling motion allows your joints to bend and move.
What Do Tendons Do?
Tendons act like bridges between muscles and bones. They move force from your muscles to your bones, so your body can move.
Key functions of tendons:
- Help your joints move (bend, straighten, rotate)
- Transfer force from muscles to bones
- Support balance and coordination
- Absorb some of the stress from movement (like running or jumping)
Without tendons, your muscles would not be able to move your skeleton.
Where Are Tendons Located?
Tendons are found throughout your entire body, from head to toe.
Common areas include:
One of the most well-known tendons is the Achilles tendon, located at the back of your ankle. It is the largest and strongest tendon in the body.
What Are Tendons Made Of?
Tendons are made mostly of collagen, a strong protein that gives them their structure and strength.
Important features:
- Rope-like structure: Built from tightly packed fibers
- Strong but not very stretchy: Designed to handle force, not stretch
- Limited blood supply: This is why tendon injuries can take longer to heal
Think of a tendon like a strong rope made of many smaller strands bundled together.
How Do Tendons Work?
Tendons work as part of a simple system:
- Your brain sends a signal to a muscle
- The muscle tightens (contracts)
- The tendon pulls on the bone
- The joint moves
Movements like this occur smoothly and almost instinctively.
Common Tendon Issues & Injuries
Because tendons are used often, they can become irritated or injured. The medical term for these tendon conditions is tendinopathy, which simply means a tendon is affected.
Common tendon conditions include:
- Tendonitis: Inflammation or irritation of a tendon (often from overuse)
- Tendinosis: Long-term damage and weakening of the tendon
- Tendon rupture: A partial or complete tear
- Tenosynovitis: Inflammation of the tendon’s protective covering
Common examples:
- Tennis elbow
- Golfer’s elbow
- Rotator cuff injuries
- Achilles tendon injuries
- Jumper’s knee
What Causes Tendon Problems?
Tendon injuries often develop from repeated stress or strain.
Common causes:
- Repetitive movements (sports, work tasks)
- Sudden increases in activity
- Poor posture or movement habits
- Aging (tendons become less flexible over time)
- Underlying health conditions
Signs of a Tendon Problem
You may have a tendon issue if you notice:
- Pain near a joint
- Tenderness when touching the area
- Swelling
- Stiffness or trouble moving
- Weakness
- A popping or clicking feeling
If symptoms continue or worsen, it’s important to seek medical care.
How Are Tendon Injuries Treated?
Most tendon problems can be treated without surgery.
Common treatments include:
RICE Method:
- Rest
- Ice
- Compression
- Elevation
Other treatment options:
- Anti-inflammatory medications (NSAIDs)
- Physical therapy to restore strength and movement
- Bracing or support devices
- Corticosteroid or PRP injections
Advanced care (if needed):
