Orthopedics(정형외과) is generally the first department to see for knee pain, as it specializes in bones, joints, muscles, and ligaments. If the pain appears related to inflammation or an autoimmune condition such as rheumatoid arthritis, a referral to Rheumatology(류마티올로지/내과 류마티스) may follow after initial evaluation.
Which department
- 1Orthopedics(정형외과)Orthopedics covers injuries and structural problems of the knee, including cartilage, ligaments, tendons, and bones. Most mechanical causes of knee pain — such as those related to overuse, trauma, or degenerative changes — are handled within this specialty. — First / second line: In Korea, you can generally start at a local orthopedic clinic(의원) for a first visit without a referral letter. If imaging or specialist-level intervention is needed, the clinic may refer you to a larger hospital(병원 or 종합병원).
- 2Rheumatology(류마티스내과)Rheumatology focuses on inflammatory and autoimmune conditions that can affect joints, including the knee — such as rheumatoid arthritis, gout, or lupus-related joint involvement. If systemic symptoms accompany knee pain, this department may be involved. — First / second line: It is common to be referred to Rheumatology from Orthopedics or Internal Medicine(내과) after initial evaluation suggests an inflammatory or systemic cause. Direct first visits are less typical but possible at larger hospitals.
- 3Sports Medicine(스포츠의학과)Sports Medicine specializes in musculoskeletal injuries related to physical activity, including knee ligament sprains, meniscal issues, and overuse injuries in active individuals. This department often bridges evaluation and rehabilitation. — First / second line: Not all hospitals have a dedicated Sports Medicine department; it is more commonly found in larger hospitals or university hospitals. Orthopedics is often the practical first stop, with Sports Medicine involvement depending on the facility.
- 4Rehabilitation Medicine(재활의학과)Rehabilitation Medicine may be involved when the focus is on restoring function and movement rather than surgical or acute intervention. It often works alongside Orthopedics in managing chronic or post-treatment knee conditions. — First / second line: Rehabilitation Medicine is generally accessed through a referral from Orthopedics or another treating department, rather than as a first point of contact for knee pain.
Go to the ER / call 119 if
If any of the following applies, do not choose a department — go to an emergency room or call 119 (Korea's emergency number).
- The knee is severely swollen, hot to the touch, and accompanied by high fever — do not wait; go to the emergency room or call 119.
- You heard or felt a loud pop in the knee during an injury and cannot bear any weight on the leg at all.
- The knee is visibly deformed or the leg appears bent in an abnormal direction after a fall or accident.
- Knee pain occurs together with chest pain, severe shortness of breath, or sudden leg swelling that extends beyond the knee — go to the emergency room immediately.
- There is a loss of sensation or sudden weakness in the lower limb alongside the knee pain.
Before your visit
- Note when the pain started, whether it began suddenly or gradually, and what you were doing at the time.
- Observe which specific part of the knee hurts — front, back, inner side, or outer side — and whether the pain is constant or comes and goes.
- Record any accompanying symptoms such as swelling, warmth, stiffness in the morning, clicking sounds, or difficulty straightening or bending the knee.
- Bring a list of any medications or supplements you are currently taking, including over-the-counter pain relievers.
- If you have had any previous X-rays, MRI scans, or blood tests related to this knee, bring those results or imaging files if possible.
- Think about whether the pain is linked to a recent injury, increased physical activity, or a longer-standing problem, as this information helps the doctor narrow down possible causes.
General principles
Knee pain is one of the most common musculoskeletal complaints and can arise from a wide range of causes, including structural issues with cartilage or ligaments, inflammatory processes, degenerative changes over time, or acute injury. Because the knee is a complex joint involving multiple structures, the appropriate department depends on what type of cause is suspected based on the pattern of symptoms.
In Korea, the general flow for knee pain typically begins at a local orthopedic clinic(정형외과 의원), where a physician takes a history and may order basic imaging. Depending on the findings, patients may continue care at the same clinic, be referred to a larger hospital for advanced imaging such as MRI, or be directed to another specialty such as Rheumatology if an inflammatory condition is suspected.
Diagnostic approaches in this area generally follow a step-by-step principle: a clinical interview and physical examination come first, followed by imaging studies as needed to assess the structures of the joint. Blood tests may also be ordered when an inflammatory or systemic cause is being considered. The specific path is determined by the clinician based on individual findings, not by the patient in advance.
Korea operates a tiered healthcare system where starting at a primary-care clinic(1차 의원) before moving to a hospital(2차 병원) or general hospital(3차 종합병원) is the general principle. A referral letter(진료의뢰서) is typically required to receive full health insurance coverage at higher-tier hospitals, so starting at a local clinic is generally both practical and cost-effective.
FAQ
Should I go to a local clinic or a large hospital for knee pain?
In Korea, it is generally advisable to start at a local orthopedic clinic(정형외과 의원) for most knee pain cases. The clinic can evaluate your condition and, if necessary, refer you to a hospital with a referral letter, which helps with health insurance coverage. Going directly to a large hospital without a referral is possible but may result in higher out-of-pocket costs.
How is orthopedic knee pain different from rheumatologic knee pain?
Orthopedics tends to address mechanical or structural causes — such as those following an injury or related to wear over time — while Rheumatology focuses on inflammatory or autoimmune causes where the immune system may be affecting the joint. In practice, a doctor's evaluation is needed to distinguish between the two, and it is common to start with Orthopedics and be referred onward if an inflammatory cause is suspected.
What kind of tests are generally done for knee pain?
A physical examination of the knee is typically the starting point, often followed by X-rays to assess bone structure. If soft tissue injury such as ligament or cartilage damage is suspected, an MRI may be considered. Blood tests may be added if inflammation or a systemic condition is part of the clinical picture. The specific tests ordered depend entirely on what the examining doctor finds and suspects.
Is knee pain evaluation different for older adults or children?
In older adults, degenerative conditions are more commonly considered, and the evaluation may take into account overall joint health and other medical conditions. In children and adolescents, growth-related conditions or activity-related injuries may be more prominent, and a pediatric orthopedic perspective may be relevant in some cases. In both groups, the general principle of starting with an Orthopedics assessment applies, and the doctor will adjust the approach based on age and individual circumstances.
