MSK
History OSCE Guide
Musculoskeletal history stations are common in OSCEs. Patients may present with joint pain, stiffness, swelling, weakness, instability, reduced movement, back pain or difficulty with daily activities.
What this Station is Testing?
In an MSK history station, the examiner wants to see that you can:
-
Identify the affected joint or area
-
Explore pain, stiffness, swelling, weakness or reduced movement
-
Work out whether the pattern is mechanical, inflammatory, traumatic, infective or neurological
-
Assess function, mobility and impact on daily life
-
Screen for red flags, especially septic joint, cauda equina, fracture, infection or malignancy
-
Cover relevant PMH, medication, family history and social history
-
Summarise the likely pattern clearly
Start with the Presenting Complaint
Start open:
-
“Can you tell me what has brought you in today?”
-
Then localise the problem:
-
“Where exactly is it?”
-
“Is it one joint or several?”
-
“Is it one side or both?”
-
“Are any other joints affected?”
If the hands are involved, clarify which joints are affected. Know the difference between PIPs, DIPs and MCPs!
The joint pattern can help distinguish mechanical from inflammatory causes.
Explore the Pain Using SOCRATES
If PAIN is the main symptom, use SOCRATES:
SITE
- “Where exactly is the pain?”
ONSET
- “When did it start? Was there any injury or trigger?”
CHARACTER
- “What does it feel like?”
RADIATION
- “What does it feel like?”
ASSOCIATED SYMPTOMS
- “Any swelling, stiffness, weakness, numbness or tingling?”
TIMING
-
“Is it constant or does it come and go? Is it worse in the morning or at night?”
EXACERBATING AND RELIEVING FACTORS
- “What makes it better or worse?”
SEVERITY
- “On a scale of 0 to 10, how bad is it?”
For lower limb symptoms, always ask about function:
“How far could you walk before this started, how far can you walk now?”
“Can you manage stairs?”
Function often tells you more than the pain score.
Not every MSK presentation is pain. The patient may describe stiffness, swelling, weakness, clicking, giving way or reduced movement.
For these symptoms, use OPERA briefly:
ONSET
“When did it start? Was there any injury or trigger?”
PROGRESSION
“Is it getting better, worse or staying the same?”
EXACERBATING & RELIEVING FACTORS
“What makes it better or worse? Is it worse with activity or after rest?”
ASSOCIATED SYMPTOMS
“Any pain, swelling, heat, redness, weakness, numbness, tingling or instability?”
If the Main Symptom is not Pain:
Work out the Pattern
Once you have explored the main symptom, step back and decide what pattern it fits.
Pattern:
Mechanical (Osteoarthritis)
Clues:
Worse with activity, better with rest, worse later in the day, clicking, crepitus or reduced movement
Pattern:
Inflammatory (Rheumatoid/Psoriatic Arthritis)
Clues:
Prolonged morning stiffness, improves with movement, swelling, warmth, redness, fatigue or small joint involvement
Pattern:
Neurological (Cauda Equina Syndrome, Spinal Cord Compression, Radiculopathy)
Clues:
Weakness, numbness, tingling, shooting pain, gait change or bladder/bowel symptoms
Pattern:
Infective (Septic Joint, Cellulitis, Necrotizing Fasciitis)
Clues:
Single erythematous, hot, swollen joint, with recent injury to the skin, spreading cellulitis, systemic temperatures and septic patient
Useful questions include:
“Are the joints stiff in the morning?”
“How long does it take to loosen up?”
“Is it worse with activity or after rest?”
“Have you noticed swelling, warmth or redness?”
“Any weakness, numbness or tingling?”
If inflammatory disease is possible, also ask about rashes, psoriasis, eye pain or redness, mouth ulcers, bowel/bladder symptoms and recent infections.
Function is one of the most important parts of an MSK history, ask:
“How is this affecting your day-to-day life?”
“Can you walk as far as usual?”
“Can you manage stairs?”
“Can you dress, wash and cook for yourself?”
“Is it affecting work, sport, sleep or mood?”
MSK symptoms are not just about pain.
They can affect independence, work, mobility, sleep and mental health.
Functional Impact
RED FLAGS
Some MSK presentations need urgent assessment.
Back pain red flags
Ask about:
-
Significant trauma
-
Severe night pain or thoracic pain
-
Fever, weight loss or night sweats
-
History of cancer
-
Immunosuppression
-
New neurological symptoms
-
Saddle anaesthesia
-
Bladder, bowel or sexual dysfunction
-
Bilateral leg symptoms
These features should make you consider serious causes such as cauda equina syndrome, spinal cord compression, infection, fracture or malignancy.
Joint red flags
Ask about:
-
Red, hot, swollen joint
-
Fever or feeling systemically unwell
-
Severe pain with reduced movement
-
Recent joint replacement
-
Immunosuppression or recent infection
-
Pain out of proportion
A septic joint is an emergency and should not be missed.
Pattern:
Traumatic (ACL, Meniscal, Soft Tissue Injury)
Clues:
Fall, twist, direct blow, sport injury, sudden pain, swelling or inability to weight bear
Past Medical and Surgical History
Ask about general medical background, then focus on relevant MSK conditions.
Look out for:
-
Previous injury or fracture
-
Previous joint surgery or replacement
-
Osteoarthritis or inflammatory arthritis
-
Psoriasis
-
Inflammatory bowel disease
-
Diabetes
-
Thyroid disease
-
Recent infection
-
Previous back problems
Drug History and Allergies
Ask about regular medications, over-the-counter treatments and allergies.
Specifically ask:
“Are you taking anything for the pain?”
“Is it helping?”
Relevant medications include NSAIDs, opioids, steroids, methotrexate, biologics, anticoagulants and recent antibiotics if tendon pain is suspected.
Always clarify allergies and the reaction.
Family History
Ask about family history of joint, bone, muscle or back problems.
If the history sounds inflammatory, ask about rheumatoid arthritis, psoriasis, inflammatory bowel disease or autoimmune disease.
Social History
In MSK histories, social history is mainly about function.
Ask about:
Living situation and support
Mobility, stairs and walking aids
Work, sport and hobbies
Manual labour, heavy lifting or repetitive movements
Caring responsibilities
Impact on sleep, mood and independence
Smoking and alcohol where relevant
Useful phrasing:
“How is this affecting your normal day?”
“Is it affecting work, sport, sleep or your mood?”
“Do you need any help at home?”
Explore the Patient’s Ideas, Concerns and Expectations.
Example Summary:
“Mrs Jones is a 68-year-old woman presenting with a six-month history of gradually worsening bilateral knee pain. The pain is worse with walking and stairs and improves with rest. She has brief morning stiffness that settles quickly. There is no significant swelling, fever, weight loss, night pain or neurological symptoms. Her symptoms are limiting her ability to walk to the shops and manage stairs. Overall, this sounds most consistent with a mechanical pattern of joint pain, such as osteoarthritis, and I would want to examine her knees and assess her function further.”
Explore the Patient’s Perspective Naturally.
“I can see this has been really affecting you. Had you any thoughts yourself about what might be going on?”
“Is there anything in particular you are worried about?”
“What were you hoping we might be able to do for you today?”
Patients may be worried about arthritis, needing surgery, losing independence, missing work or being stuck on a waiting list.
If they are frustrated, acknowledge it:
“I can understand why this is frustrating, especially if it has been going on for a long time and is affecting your daily life.”
Possible Examiner Questions & Model Answers
Q1: What are your top differential diagnoses?
This depends on the joint and pattern.
Mechanical pain suggests osteoarthritis, tendon problems or mechanical back pain.
Inflammatory pain suggests rheumatoid arthritis, psoriatic arthritis or another inflammatory arthritis. A red, hot, swollen joint should make you think about septic arthritis or crystal arthritis.
Back pain with neurological symptoms or bladder/bowel dysfunction should make you think about cauda equina syndrome or spinal cord compression.
Q3: What would you examine?
I would examine the affected joint using look, feel, move and compare both sides.
I would assess swelling, warmth, tenderness, deformity, range of movement and function.
I would also examine the joint above and below. If there were back pain or neurological symptoms, I would assess the spine/lower limb neurology and screen for cauda equina features. This may require a digital rectal examination also.
Q2: How would you distinguish osteoarthritis from rheumatoid arthritis?
Osteoarthritis is usually mechanical: worse with use, better with rest and brief stiffness. It often affects knees, hips, DIP joints and the thumb base.
Rheumatoid arthritis is usually inflammatory: prolonged morning stiffness, improvement with movement and symmetrical small joint involvement, especially MCP and PIP joints.
Quick MSK History Structure
A simple MSK history can be structured around:
Identify the affected joint or area
Explore pain with SOCRATES
Ask about stiffness, swelling, weakness and instability
Work out the pattern
Assess function
Screen for red flags
Cover PMH, drugs, family history and social history
Explore ICE
Summarise and suggest examination if asked
Key Message
A strong MSK History is about pattern recognition.
Work out the exact joint, the pattern of symptons, whether there are red flags, and how much it is affecting the patients life.
In MSK histories, function matters. Pain that stops someone walking, working, sleeping or looking after themselves is not a minor symptom.
