What are the recommended management strategies for osteoarthritis?

Osteoarthritis Treatment

All patients with osteoarthritis should receive a core triad of exercise, patient education, and weight loss (if overweight/obese) as first-line therapy, with NSAIDs and surgical intervention reserved for those who fail to improve with these foundational treatments. 1

Core Non-Pharmacological Treatments (Required for All Patients)

The following three interventions form the foundation of osteoarthritis management and should be offered to every patient:

Exercise Programs

• Implement structured exercise including strengthening, low-impact aerobic activity, and neuromuscular training with adequate dosage and progression tailored to physical function 1
• Exercise modality (individual/group, supervised/unsupervised, land/aquatic) should be selected based on local availability and patient preference 1
• Self-management programs, strengthening exercises, and neuromuscular education are strongly recommended 1
• Specific options include tai chi (strongly recommended), yoga, and balance exercises 1

Patient Education and Self-Management

• Provide information to counter the misconception that osteoarthritis is inevitably progressive and untreatable 1
• Education and self-management strategies should be reinforced at every clinical encounter 1
• This represents the highest priority recommendation for implementation according to recent guidelines 1

Weight Management

• Patients with BMI ≥25 kg/m² must be offered weight loss interventions 1
• Weight reduction is appropriate for all overweight/obese patients with hip or knee osteoarthritis 1

Adjunctive Non-Pharmacological Interventions

After establishing core treatments, consider:

• Hand orthoses for first carpometacarpal (CMC) joint osteoarthritis (strongly recommended) 1
• Walking aids and appropriate shock-absorbing footwear 1
• Assistive devices for activities of daily living 1
• Bracing for tibiofemoral osteoarthritis (strongly recommended) or patellofemoral involvement 1
• Local heat or cold applications 1
• Manipulation and stretching, particularly for hip osteoarthritis 1
• TENS (transcutaneous electrical nerve stimulation) 1
• Behavior change techniques when lifestyle modifications are needed 1

Pharmacological Management Algorithm

First-Line Pharmacotherapy

For knee and hand osteoarthritis, start with paracetamol (acetaminophen) and/or topical NSAIDs before considering oral NSAIDs 1

• Paracetamol: Regular dosing may be needed for adequate pain relief 1
• Topical NSAIDs: Strongly recommended for knee osteoarthritis 1
• Topical capsaicin: Consider for knee osteoarthritis 1

Second-Line Pharmacotherapy

If paracetamol or topical NSAIDs provide insufficient relief:

• Oral NSAIDs or COX-2 inhibitors at the lowest effective dose for the shortest duration 1
• Prescribe with a proton pump inhibitor (choose lowest acquisition cost) 1
• COX-2 inhibitor (other than etoricoxib 60 mg) or standard NSAID are first choices 1
• Account for individual risk factors including age, gastrointestinal, liver, and cardiorenal toxicity 1
• Oral NSAIDs are strongly recommended for hand, knee, and hip osteoarthritis 1

Additional Pharmacological Options

• Duloxetine: Conditionally recommended 1
• Tramadol: Recommended as an option 1
• Opioid analgesics: Consider adding if paracetamol/topical NSAIDs insufficient 1

Intra-articular Injections

• Corticosteroid injections for knee and/or hip osteoarthritis: Strongly recommended 1
• Corticosteroid injections for hand osteoarthritis: Conditionally recommended 1
• Hyaluronic acid injections are NOT recommended 1

Treatments NOT Recommended

The following interventions should be avoided based on strong evidence:

• Glucosamine and chondroitin: Not recommended 1
• Acupuncture: Not recommended (most studies not statistically significant) 1
• Electroacupuncture: Should not be used 1
• Hyaluronic acid injections for knee osteoarthritis: Not recommended 1
• Stem cell injections for hip and knee: Consistently recommended against 2
• Arthroscopy: Consistently recommended against 2

Surgical Intervention

Reserve surgical interventions (including total joint replacement) for disabling osteoarthritis that has not improved with comprehensive nonsurgical care 1

Critical Implementation Points

Common Pitfalls to Avoid

• Do not treat osteoarthritis with single interventions alone—the evidence supports multicomponent management plans 1
• Do not skip core treatments (exercise, education, weight loss) and jump directly to pharmacotherapy 1
• Do not use NSAIDs without gastroprotection in at-risk patients 1
• Do not continue ineffective treatments like glucosamine/chondroitin despite patient requests 1

Nuances in the Evidence

While the 2023 systematic review of high-quality guidelines 1 provides the most recent synthesis, there is notable divergence on certain interventions. The AAOS guidelines 1 take a stronger stance against acupuncture and hyaluronic acid compared to NICE 1 and ACR/AF 1 recommendations. The most recent EULAR 2023 update 1 emphasizes behavior change techniques as a distinct recommendation, reflecting evolving understanding of adherence barriers.

Work-Related Considerations

Patients with or at risk of work disability should receive timely advice on modifiable work-related factors with appropriate referral for expert guidance 1
