An orthopedic doctor is a physician who specializes in diagnosing and treating problems with your bones, muscles, joints, and the soft tissues that connect them, like ligaments and tendons. Some focus entirely on surgery, while others spend most of their time managing conditions without operating. There are roughly 25,000 orthopedic surgeons actively seeing patients in the United States, making it one of the larger surgical specialties.
What Orthopedic Doctors Treat
The musculoskeletal system covers a lot of territory, so orthopedic doctors handle a wide range of problems. Common conditions include arthritis (particularly osteoarthritis), fractures, sports injuries, sprains and strains, tendinitis, bursitis, and neck or lower back pain. They also treat structural issues like scoliosis and congenital conditions such as clubfoot or hip dysplasia. Some specialize in bone and soft tissue tumors.
What ties all of this together is the focus on how your body moves. If something in your skeleton, joints, or connective tissue is damaged, misaligned, or degenerating, an orthopedic doctor is typically the specialist who manages it.
They Don’t Just Do Surgery
The formal title is “orthopedic surgeon,” which gives people the impression that every visit ends with an operation. In practice, a large portion of orthopedic care is non-surgical. Orthopedic doctors regularly prescribe physical therapy, design at-home exercise plans, fit braces or supports, and perform joint injections to reduce pain and inflammation.
Cortisone injections are one of the most common tools, used for arthritis, carpal tunnel syndrome, and tendinitis in the hands, hips, knees, shoulders, spine, or wrists. Gel injections (viscosupplementation) add cushioning fluid to arthritic knees. Platelet-rich plasma (PRP) injections use your own blood cells to accelerate healing in damaged tendons, ligaments, and joints. Shockwave therapy uses sound waves to promote tissue repair without any incision at all.
Surgery is generally on the table when conservative treatments haven’t worked or when the injury is too severe to heal on its own, like a complex fracture or a torn ligament that won’t stabilize.
Common Surgical Procedures
Joint replacement is probably the procedure most associated with orthopedic surgeons. Hip and knee replacements are now routine, with knee replacement alone carrying a success rate between 90% and 98%. Shoulder and elbow replacements have also become more common as the technology has improved. Beyond replacement, orthopedic surgeons perform arthroscopic surgery (using a small camera and instruments inserted through tiny incisions), fracture repair with plates, screws, or rods, spinal fusions, and ligament reconstructions like ACL repair.
Subspecialties Within Orthopedics
After completing their general training, many orthopedic doctors pursue a fellowship in a specific area. The recognized subspecialties include:
- Sports medicine: Injuries from athletics, with heavy use of arthroscopic techniques
- Joint replacement and adult reconstruction: Hip, knee, shoulder, and elbow replacements, including revision surgery when a previous implant fails
- Spine: Conditions ranging from herniated discs and degenerative disease to scoliosis, often involving spinal fusion or instrumentation
- Hand and upper extremity: Everything from carpal tunnel and tendon repairs to replanting amputated fingers
- Foot and ankle: Sports injuries, diabetic foot complications, forefoot deformities, and trauma
- Trauma: Acute fracture management and stabilization, covering all body regions and age groups
- Oncology: Benign and malignant tumors of bone and soft tissue
This means the orthopedic doctor treating your torn rotator cuff may have a completely different skill set than the one managing your teenager’s scoliosis. If your condition is complex, asking whether your surgeon has fellowship training in that specific area is reasonable.
How They Diagnose Problems
An orthopedic visit typically starts with a physical exam, where the doctor tests your range of motion, stability, and strength. From there, imaging helps confirm what’s going on. X-rays are the most common starting point for evaluating bones and joint alignment. MRI scans, which use magnets and radio waves instead of radiation, are better at showing soft tissue like torn ligaments, cartilage damage, or disc problems in the spine.
CT scans create detailed cross-sectional images and are useful for complex fractures. Ultrasound is particularly helpful because it produces real-time images while you move, letting the doctor see exactly what happens in the joint during the motion that causes your pain. Bone density scans measure mineral content in your bones and are used to diagnose osteoporosis, typically targeting the hip and spine. In some cases, fluid is drawn from a joint (aspiration) and sent to a lab to check for infection or gout.
Their Training
Orthopedic doctors complete four years of medical school followed by a five-year orthopedic surgery residency. Those who subspecialize add one to two more years of fellowship training. That puts the total at 13 to 14 years of education and training after high school, making it one of the longer paths in medicine.
How They Differ From Similar Specialists
Physiatrists (physical medicine and rehabilitation doctors) also treat musculoskeletal pain, but their approach is fundamentally non-surgical. They focus on restoring function through conservative methods like therapy, injections, and lifestyle modifications. A physiatrist fills the gap between when pain starts and when surgery becomes necessary. If you need a structural repair, a fracture fixed, or a joint replaced, that’s the orthopedic surgeon’s role.
Rheumatologists overlap with orthopedic doctors in treating arthritis, but they focus on autoimmune and inflammatory forms like rheumatoid arthritis and lupus, managing them primarily with medications rather than surgery. Orthopedic doctors handle the mechanical side: when the joint has physically worn out or broken down to the point where it needs repair or replacement.
Signs You Should See One
Pain lasting two or more weeks without improvement is a reasonable threshold for scheduling an orthopedic visit, especially if it came from an injury. Other signals include difficulty bearing weight on a leg or foot, which can point to a fracture, severe sprain, or muscle injury. If pain is interfering with basic daily tasks like climbing stairs, getting in and out of a car, or buttoning a shirt, that level of functional limitation is exactly what orthopedic doctors are trained to evaluate. Sports injuries involving a hard landing, sudden pivot, or collision are also worth an orthopedic assessment, since ligament and cartilage damage isn’t always obvious from the outside.
