Management of Osteoarthritis
All patients with osteoarthritis should begin with a foundation of exercise, weight loss (if overweight/obese), and self-management education before escalating to pharmacological therapies, as these core non-pharmacological interventions improve both pain and function with minimal risk. 1, 2, 3
Core Non-Pharmacological Treatments (Universal for All Patients)
Exercise (Strongly Recommended)
- Exercise is the cornerstone of osteoarthritis management and should be prescribed to every patient regardless of joint involvement. 1, 2, 3
- Acceptable forms include walking, strengthening exercises, aquatic exercise, and neuromuscular training—no single type is superior, so patient preference and access should guide selection. 1, 2
- Supervised exercise programs (often delivered by physical therapists) are more effective than home-based programs alone, particularly when combined with self-management education. 1
- Patients experiencing pain should not avoid exercise; clinical trials demonstrate benefit even in symptomatic patients, and shared decision-making should determine when to initiate rather than arbitrary pain thresholds. 1
Weight Loss (Strongly Recommended)
- Weight loss of ≥5% body weight produces clinically meaningful improvements in knee and hip osteoarthritis, with greater benefits at 10-20% loss. 1, 2, 3
- Weight loss combined with exercise produces superior outcomes compared to either intervention alone. 1
Self-Management and Patient Education (Strongly Recommended)
- Provide structured self-management programs that combine skill-building (goal-setting, problem-solving), disease education, joint protection strategies, and fitness instruction. 1, 2, 3
- Counter the misconception that osteoarthritis is inevitably progressive and untreatable. 1
- These programs can be delivered by health educators, nurses, physical therapists, or peer leaders, either in-person or online. 1
Mind-Body Approaches
- Tai chi is strongly recommended for knee and hip osteoarthritis, combining physical movement with meditation, breathing, and relaxation to improve strength, balance, pain, and self-efficacy. 1
- Yoga is conditionally recommended for knee osteoarthritis but lacks sufficient data for hip osteoarthritis. 1
Joint-Specific Physical Modalities
Hand Osteoarthritis
- First carpometacarpal (CMC) joint orthoses (rigid or neoprene) are strongly recommended for thumb base osteoarthritis. 1, 2, 3
- Orthoses for other hand joints are conditionally recommended. 1, 2
Knee Osteoarthritis
- Tibiofemoral bracing is strongly recommended for tibiofemoral osteoarthritis. 1, 2, 3
- Patellofemoral bracing is conditionally recommended for patellofemoral osteoarthritis. 1, 2
- Lateral heel wedges should NOT be prescribed for medial compartmental knee osteoarthritis. 3
Hip Osteoarthritis
- Cane use is strongly recommended to reduce joint load and improve mobility. 2, 3
- Manipulation and stretching are particularly beneficial for hip osteoarthritis. 1
Additional Physical Modalities
- Local heat or cold applications provide symptomatic relief. 1, 2
- Transcutaneous electrical nerve stimulation (TENS) can be used for pain management. 1
- Balance exercises are conditionally recommended for knee and hip osteoarthritis. 1, 2
- Assistive devices (walking sticks, tap turners) should be provided for patients with specific functional limitations. 1
Pharmacological Treatment Algorithm
Step 1: Topical Therapies (First-Line for Accessible Joints)
- Topical NSAIDs are strongly recommended as first-line pharmacological treatment for knee osteoarthritis, providing effective pain relief with minimal systemic exposure and lower risk than oral NSAIDs. 2, 4, 3
- Topical NSAIDs should also be considered for hand osteoarthritis before oral agents. 1
- Topical capsaicin is an alternative option for knee and hand osteoarthritis. 1
Step 2: Oral Analgesics
- Acetaminophen (paracetamol) up to 4,000 mg/day can be tried for mild-to-moderate pain, though recent evidence shows limited efficacy compared to NSAIDs. 1, 2, 4
- Regular dosing may be more effective than as-needed administration. 1
- Monitor for hepatotoxicity, particularly in elderly patients or those with liver disease. 4
Step 3: Oral NSAIDs (When Topical Therapy Insufficient)
- Oral NSAIDs are strongly recommended for hand, knee, and hip osteoarthritis when topical treatments fail, but use the lowest effective dose for the shortest duration. 1, 2, 3, 5
- Choose between a standard NSAID or COX-2 inhibitor (other than etoricoxib 60 mg) based on individual risk factors. 1
- Always co-prescribe a proton pump inhibitor with oral NSAIDs or COX-2 inhibitors to reduce gastrointestinal risk, selecting the lowest-cost option. 1, 3
- Before prescribing, assess cardiovascular, gastrointestinal, renal, and hepatic risk factors, particularly in elderly patients. 1, 4
- NSAIDs demonstrate comparable analgesic efficacy to aspirin and indomethacin but with fewer gastrointestinal and nervous system adverse effects. 5
- For patients requiring low-dose aspirin, consider other analgesics before adding NSAIDs due to increased bleeding risk. 1
Step 4: Duloxetine (For Refractory Cases or Comorbid Depression)
- Duloxetine is conditionally recommended for patients with inadequate response to first-line treatments or those with comorbid depression. 2, 3
Step 5: Tramadol (Reserve for Refractory Cases)
- Tramadol is conditionally recommended only when other options have failed, recognizing risks of dependence, falls, and cognitive impairment, particularly in elderly patients. 2, 3
Intra-Articular Injections
Corticosteroid Injections
- Corticosteroid injections are strongly recommended for knee and hip osteoarthritis to provide short-term pain relief (4-8 weeks) during acute flares. 2, 3, 6
- Effective for painful flares in hand osteoarthritis, especially the trapeziometacarpal joint. 3
- These provide inexpensive, rapid relief but do not alter disease progression. 7, 6
Hyaluronic Acid Injections
- Hyaluronic acid injections are more expensive than corticosteroids but may maintain symptom improvement for longer periods in knee osteoarthritis. 7, 6
Treatments NOT Recommended
The following interventions should be avoided as they lack evidence of benefit:
- Glucosamine and chondroitin products are NOT recommended despite popular use, as they show no significant benefit over placebo. 1, 2, 4, 3, 8
- Electroacupuncture should NOT be used. 1, 2, 3
- Acupuncture has insufficient evidence for firm recommendation. 1
- Arthroscopic lavage or débridement should NOT be routinely performed, as these procedures show no benefit over sham surgery or optimized medical therapy. 3, 8
Surgical Considerations
- Joint replacement surgery (hip, knee, shoulder) should be reserved for patients with severe osteoarthritis and chronic pain/disability despite maximal medical management, as it generally provides excellent results. 4, 3, 7, 8, 6
- Partial meniscectomy or loose body removal may be considered when specific mechanical symptoms are present. 3
- Realignment osteotomy may be appropriate for select candidates. 3
- For severe thumb base osteoarthritis refractory to conservative treatment, consider interposition arthroplasty, osteotomy, or arthrodesis. 3
Critical Implementation Points
Holistic Assessment
- Assess the impact of osteoarthritis on function, quality of life, occupation, mood, relationships, and leisure activities at each visit. 1
- Formulate management plans in partnership with patients, considering comorbidities that compound osteoarthritis effects. 1
- Provide periodic review tailored to individual needs, as disease course and requirements change over time. 1, 4, 9
Common Pitfalls to Avoid
- Do not combine NSAIDs with aspirin, as aspirin increases NSAID excretion and the combination increases adverse event frequency without proven additional benefit. 5
- Do not prescribe NSAIDs without gastroprotection in at-risk patients. 1, 3
- Do not delay exercise prescription due to patient pain—supervised programs with gradual progression are safe and effective even in symptomatic patients. 1
- Do not rely solely on pharmacological therapy; the evidence strongly supports non-pharmacological interventions as foundational treatment. 1, 2, 3
