What Is an Orthopaedic Surgeon?

An orthopaedic surgeon is a medical doctor who focuses on problems that affect how your body moves, including bones, joints, muscles, ligaments, and tendons. If pain, injury, or wear and tear is limiting your ability to walk, lift, reach, or stay active, an orthopaedic surgeon helps determine the cause and guides the next steps for treatment.

Care does not always begin with surgery. Your orthopaedic surgeon takes time to evaluate symptoms, review imaging, and understand how a condition affects your daily life. In many cases, treatment may start with non-surgical options such as physical therapy, activity modification, or targeted injections.

When surgery is the most appropriate option, certain orthopaedic procedures can be performed safely in an ambulatory surgery center setting, like the Andrews Institute. This allows patients to return home the same day with a structured recovery plan and ongoing support from their care team.

Conditions Treated by Orthopaedic Surgeons

Movement and joint issues can take many forms, from acute injuries to gradual wear and tear. Orthopaedic care focuses on both the underlying condition and how it affects daily activity, work, or athletic performance. Common conditions treated include:

  • Joint pain and arthritis
  • Sports injuries
  • Fractures and trauma
  • Tendon and ligament injuries
  • Degenerative joint conditions

Frequently Asked Questions

What does orthopaedic mean?

Orthopaedic refers to the area of medicine focused on the musculoskeletal system. This includes bones, joints, muscles, ligaments, tendons, and nerves that support movement and physical function. Orthopaedic care helps address injuries, pain, and conditions that affect how your body moves and bears weight.

What does “ortho” mean in medical terms?

In medical terms, “ortho” comes from Greek roots meaning “straight” or “correct.” In orthopaedics, it refers to correcting or supporting the structure and function of the musculoskeletal system. You’ll often see it used as shorthand in terms like orthopaedic care, orthopaedic surgery, or orthopaedic specialist.

What is an orthopaedic injury?

An orthopaedic injury is any injury that affects the bones, joints, muscles, ligaments, or tendons. This can include fractures, sprains, tendon tears, joint injuries, or damage caused by overuse or repetitive motion. Some injuries happen suddenly, such as from a fall or sports activity, while others develop gradually over time.

When should I see an orthopaedic doctor?

You may want to see an orthopaedic doctor if pain, stiffness, or limited movement is interfering with your daily life. This includes pain that does not improve with rest, keeps returning, or makes it difficult to work, exercise, or perform routine activities. Persistent joint pain, swelling, or weakness are also common reasons to seek orthopaedic care.

Why would I be referred to an orthopaedic surgeon?

A referral to an orthopaedic surgeon usually means your provider wants a specialist to evaluate a bone, joint, or muscle condition more closely. This does not always mean surgery is needed. Orthopaedic surgeons also diagnose conditions, recommend non-surgical treatments, and help determine whether a procedure is appropriate based on your symptoms and goals.

What are the signs you should see an orthopaedic specialist?

Common signs include ongoing joint pain, reduced range of motion, instability, swelling, or pain that worsens with activity. Difficulty walking, lifting, gripping, or returning to normal movement after an injury may also indicate the need for orthopaedic evaluation.

What are early signs of orthopaedic issues?

Early signs can be subtle and may include stiffness, aching after activity, clicking or catching in a joint, or mild swelling that keeps returning. Addressing these symptoms early can help prevent further injury and may allow for more conservative treatment options.
