Treatment of Stage 1 Osteoarthritis
All patients with stage 1 osteoarthritis should immediately begin a structured exercise program combined with weight loss if overweight, before considering any pharmacological interventions. 1, 2
Core Non-Pharmacological Treatments (Start Here for ALL Patients)
Stage 1 osteoarthritis requires an aggressive non-pharmacological approach as the foundation of treatment. These interventions are strongly recommended and should be initiated simultaneously:
Exercise Programs (Mandatory First-Line)
- Participate in cardiovascular (aerobic) exercise at least 30 minutes most days of the week - options include walking, cycling, or swimming based on patient preference and joint tolerance 1, 3
- Engage in resistance/strengthening exercises targeting muscles around affected joints, using elastic bands, weight machines, or isometric exercises 1
- Aquatic exercise programs are equally effective as land-based exercise and should be chosen based on patient preference and aerobic conditioning level 1
- Neuromuscular training addresses muscle weakness and proprioceptive deficits that develop early in osteoarthritis 1
The evidence strongly supports exercise across all guidelines, with the 2019 ACR/Arthritis Foundation guideline providing the strongest recommendation. 1 While older guidelines from 2012 also strongly recommend exercise, the 2019 update emphasizes that no single exercise type is superior - patient adherence and preference are the critical factors. 1
Weight Management (If BMI ≥25 kg/m²)
- Achieve 5-10% body weight reduction through caloric restriction and increased physical activity 2, 4
- Weight loss is strongly recommended specifically for knee and hip osteoarthritis to reduce mechanical joint load 1
Self-Management and Education
- Enroll in structured self-management programs that teach coping strategies, disease understanding, and self-efficacy skills 1, 2, 5
- Patient education has been shown to reduce pain and improve function in 19 of 20 studies reviewed 5
Joint-Specific Physical Modalities
Add these based on which joints are affected:
For Hand OA
- First carpometacarpal (CMC) joint orthoses (custom-made rigid or neoprene splints) are strongly recommended for thumb base involvement 2, 6
For Knee OA
- Tibiofemoral bracing is strongly recommended for tibiofemoral compartment disease 2, 6
- Medially directed patellar taping can be used conditionally 1
- Walking aids (cane) should be prescribed to reduce joint load and improve mobility 2, 6
For Hip OA
Thermal Therapy
- Local heat application (hot packs, paraffin wax) before exercise provides temporary symptomatic relief 1, 2, 4
- Cold applications can be alternated with heat based on patient response 1, 2
Pharmacological Treatment (Add Only If Inadequate Response to Above)
The 2019 ACR guideline emphasizes starting with treatments having the least systemic exposure. 1 Progress through this hierarchy:
First-Line Pharmacological Options
- Topical NSAIDs are strongly recommended for knee OA as initial pharmacological therapy due to effective pain relief with minimal systemic absorption 2, 6
- Acetaminophen up to 4,000 mg/day in divided doses can be used for mild-to-moderate pain, though recent guidelines have downgraded its importance due to limited efficacy 1, 2
Critical caveat: When prescribing acetaminophen, counsel patients to avoid all other acetaminophen-containing products including over-the-counter cold remedies and combination opioid products. 1
Second-Line Pharmacological Options (If First-Line Inadequate)
- Oral NSAIDs are strongly recommended for hand, knee, and hip OA when topical treatments fail, but use the lowest effective dose for the shortest duration 1, 2, 6
- Co-prescribe a proton pump inhibitor with all oral NSAIDs or COX-2 inhibitors to reduce gastrointestinal risk 1, 6
- Consider individual cardiovascular, renal, and gastrointestinal risk factors before prescribing, as all oral NSAIDs carry similar analgesic efficacy but vary in toxicity profiles 1
Intra-Articular Corticosteroid Injections
- Use for moderate-to-severe pain flares in knee, hip, or hand (especially trapeziometacarpal joint) for short-term relief (4-8 weeks) 1, 2, 6, 7
Third-Line Options (Reserve for Refractory Cases)
- Tramadol is conditionally recommended only when NSAIDs are contraindicated or ineffective, but carries dependence and side effect risks 1, 2
- Duloxetine can be considered for patients with inadequate response to first-line treatments or comorbid depression 2
Treatments to AVOID in Stage 1 OA
These have insufficient evidence or are not recommended:
- Glucosamine and chondroitin are not recommended despite popular use 1, 2, 6
- Topical capsaicin is not recommended 1
- Acupuncture (including electroacupuncture) is not recommended 1, 6
- Hyaluronic acid injections are not recommended by AAOS guidelines 1
- Opioid analgesics should be avoided in stage 1 disease 8
Common Pitfalls to Avoid
- Do not start with pharmacological treatment alone - exercise and weight management must be the foundation 1, 2, 8
- Do not prescribe oral NSAIDs without gastroprotection in at-risk patients 1, 6
- Do not continue ineffective acetaminophen - if no response after adequate trial, escalate to NSAIDs 1
- Do not refer for arthroscopic lavage/debridement - this is not indicated for stage 1 OA 1, 6
