Rapid review
- 68-year-old employed male with bilateral knee osteoarthritis (R > L) and right-knee instability on stair descent1; pain 2–3/10 baseline rising to 7–8/10 at worst2, sharp and stabbing3, intermittent and progressively worsening over years4.
- Active fall-risk concern on stair descent with load-carrying — patient explicitly endorses the knee “may give out”5; pattern is progressive, not acute. Lifestyle modification refused on principle6.
- Sleep insufficiency (~6 h/night) attributed to frequent work travel, not pain7; no psychiatric risk indicators: PHQ-8 0% (5), AUDIT-C low-moderate (4/12, 33%), DAST-10 1/10, no suicidal/homicidal ideation8.
- Strong protective profile: dense social network (wife, sister, multiple long-term friends), life-satisfaction 9–10/10, intact treatment understanding, ibuprofen 600 mg providing partial relief9.
- Patient expresses a clinically actionable value-action tension: he understands the risk, prefers maintaining lifestyle over modification, and asks for help managing pain without giving up valued activities10.
Risk assessment
T1 Low — Functional Safety · MonitorSummary of patient needs
- Orthopedic evaluation for progressive right-knee OA with fall-risk semiology (patient-acknowledged).
- Pain-management plan compatible with frequent work travel — escalation beyond ibuprofen 600 mg when partial relief insufficient.
- Shared decision-making around lifestyle modification: address the value-action tension without coercive framing.
- Sleep evaluation in the context of work travel; consider whether 6 h/night reflects schedule or unrecognized pathology.
- Continuity with patient's strong informal supports — engage spouse if/when treatment plans change.
Domain 01 Key Information & Presenting Concern
Patient is a 68-year-old married, employed male evaluated across two CAS sessions for bilateral knee osteoarthritis with progressive right-knee involvement and patient-reported instability under load-carrying on stair descent.
Onset, course, and trigger to seek care
- Onset
- Years (described as ongoing process)11
- Trajectory
- Progressively worsening; intermittent with high day-to-day variability4
- Trigger to present
- Right-knee instability under load on stair descent with frequent business travel5
- Patient framing
- Attributes exacerbation to prior hip replacement on contralateral side12
Pain profile
- Location
- Bilateral knees; right > left13
- Quality
- Sharp, stabbing3
- Intensity
- Session 1: 2–3/10 baseline · 7–8/10 worst. Session 2: 3–4/10 baseline · one day reached 7/102
- Pattern
- Intermittent; high intra-day and day-to-day variability4
- Aggravators
- Walking · going downstairs · sit-to-stand transitions · carrying heavy loads · weather changes · prolonged inactivity14
- Alleviators
- Sleep · ibuprofen 600 mg · physical therapy · acetaminophen · slow initial walking after standing · ongoing activity15
Domain 02 Medical History
Active & current diagnoses
- Primary
- Osteoarthritis, bilateral knees · right knee more symptomatic Active
- Comorbid
- Obesity (patient attributes contribution to knee aggravation)16
- Surgical
- History of hip replacement (date / side not captured this encounter) Verify
Domain 04 Mental Health & Substance Use Screening
Mood, anxiety, sleep
Patient denies depressed mood, anhedonia, hopelessness, and pain catastrophizing across both sessions. Anxiety screening below clinical threshold. Psychosocial functioning reported as notably intact: PHQ-8 0%, PCS 0%, PCL-5 4%, life-satisfaction 9–10/10, dense social support8.
Domain 05 Functional Status
Day-to-day functioning is largely preserved with two domains showing measurable knee-pain interference (recreation and exercise). Patient continues full-time employment with frequent business travel, manages personal medication and self-care independently.
- Work / income
- Employed full-time; frequent travel for work; No impact from pain21
- Daily activities
- Minimal pain interference; ADLs preserved Minimal
- Sleep
- ~6 h/night, attributed to work travel rather than pain22
- Recreation
- Moderate pain interference reported24 Moderate
- Exercise
- Self-modifications during prolonged sitting before loading25 Self-edits
- Self-care
- Independent — manages medications appropriately27
