Management of Osteoarthritis
All patients with osteoarthritis should receive three core treatments immediately: exercise therapy (including local muscle strengthening and general aerobic fitness), weight loss interventions if overweight or obese, and patient education to counter misconceptions about the disease. 1
Core First-Line Treatments (Non-Negotiable for All Patients)
These interventions form the foundation of osteoarthritis management and should be initiated before or alongside any other treatments:
Exercise Therapy (Strongly Recommended)
- Exercise is the single most important non-pharmacological intervention and should be prescribed to every patient with knee, hip, or hand osteoarthritis 1
- Multiple exercise modalities are effective, including walking, stationary cycling, resistance training with elastic bands or weight machines, aquatic exercise, and neuromuscular training 1
- No specific exercise type has proven superior to others; choose based on patient preference and accessibility rather than seeking an "optimal" regimen 1
- Patients experiencing pain should not avoid exercise—clinical trials demonstrate that symptomatic patients can participate in and benefit from exercise programs 1
- Referral to physical or occupational therapy is beneficial at various disease stages for proper instruction, self-efficacy training, and maintenance of exercise adherence 1
Weight Loss (If Overweight/Obese)
- Weight reduction is strongly recommended as it directly reduces mechanical stress on weight-bearing joints 1
- This intervention should be implemented early and maintained throughout disease management 1
Patient Education
- Provide both oral and written information to enhance understanding and counter the misconception that osteoarthritis is inevitably progressive and untreatable 1
- Education improves treatment adherence and overall outcomes 1
Pharmacological Treatment Algorithm
Step 1: First-Line Analgesics
- Start with acetaminophen (paracetamol) at regular dosing up to 4,000 mg/day for pain relief 1, 2
- For knee and hand osteoarthritis specifically, use topical NSAIDs before oral NSAIDs due to fewer systemic side effects 1, 2
- Topical capsaicin can be added for additional pain relief in knee and hand osteoarthritis 1
Step 2: Oral NSAIDs/COX-2 Inhibitors (When First-Line Insufficient)
- If acetaminophen and topical NSAIDs fail to provide adequate pain relief, escalate to oral NSAIDs or COX-2 inhibitors 1
- Use the lowest effective dose for the shortest possible duration 1
- Choose either a COX-2 inhibitor (other than etoricoxib 60 mg) or a standard NSAID 1
- Always co-prescribe a proton pump inhibitor for gastroprotection, selecting the lowest acquisition cost option 1
- Before prescribing, assess cardiovascular, gastrointestinal, liver, and renal risk factors, particularly in elderly patients 1
- Ibuprofen dosing for osteoarthritis: 1200-3200 mg daily (400-800 mg three to four times daily), though doses above 2400 mg rarely provide additional benefit 3
- Naproxen dosing: 375-750 mg twice daily, with the 750 mg twice daily dose associated with higher adverse event rates 4
Step 3: Opioid Analgesics (When NSAIDs Insufficient or Contraindicated)
- Add opioid analgesics if previous treatments are inadequate, recognizing the risks of long-term opioid use 1
- Can be used in combination with acetaminophen or as a substitute 1
Step 4: Intra-articular Injections
- Intra-articular corticosteroid injections are specifically indicated for knee pain with effusion and can provide short-term pain relief during disease flares 5, 6
- Intra-articular hyaluronic acid products may be considered for inadequate pain relief with oral medications 6
Adjunct Non-Pharmacological Treatments
Physical Modalities
- Local heat or cold applications provide temporary pain relief 1
- Transcutaneous electrical nerve stimulation (TENS) can be used for pain management 1
- Manipulation and stretching, particularly for hip osteoarthritis, may provide benefit when combined with exercise 1
Assistive Devices and Supports
- Assess for bracing, joint supports, or insoles in patients with biomechanical joint pain or instability 1
- Provide assistive devices (walking sticks, tap turners) for those with specific problems in activities of daily living 1
- Consider occupational therapy referral for expert assessment 1
Behavioral Modifications
- Recommend appropriate footwear with shock-absorbing properties 1
- Teach activity pacing to avoid "peaks and troughs" of activity that exacerbate symptoms 1
Treatments NOT Recommended
Do not use the following interventions, as evidence does not support their efficacy:
- Glucosamine and chondroitin products are not recommended despite their popularity, as they have not demonstrated significant benefits over placebo 1, 2, 7
- Electroacupuncture should not be used 1
- Traditional acupuncture has insufficient evidence for a firm recommendation 1
Critical Monitoring and Safety Considerations
NSAID Risk Assessment (Essential Before Prescribing)
- All oral NSAIDs and COX-2 inhibitors have similar analgesic efficacy but differ significantly in gastrointestinal, liver, and cardiorenal toxicity 1
- Age is a major risk factor—elderly patients require particularly careful assessment 1
- Consider ongoing monitoring of risk factors during treatment 1
- Avoid combining NSAIDs with aspirin, as aspirin increases naproxen excretion and the combination increases adverse event frequency without proven additional benefit 4
Periodic Review
- Provide regular follow-up tailored to individual needs, as disease course and patient requirements change over time 1
- Reassess treatment effectiveness and adjust the management plan accordingly 1
Holistic Assessment Framework
At each visit, assess the impact of osteoarthritis on:
- Function and activities of daily living 1
- Quality of life 1
- Occupation and work capacity 1
- Mood and psychological well-being 1
- Relationships and social activities 1
- Leisure activities 1
Formulate the management plan in partnership with the patient, considering comorbidities that compound osteoarthritis effects 1
Surgical Considerations
- Joint replacement surgery should be considered only after offering core treatment options and when conservative management fails to provide adequate pain relief and functional improvement 2
- Arthroscopic procedures have not shown benefit over sham procedures or optimized physical and medical therapy and should be avoided 7
- Surgery is appropriate for patients with joint symptoms that substantially impact quality of life despite comprehensive conservative management 2
