Treatment of Degenerative Arthritis in the Foot for a 79-year-old Female with Hypertension

The best treatment approach for degenerative arthritis in the foot of a 79-year-old female with hypertension should begin with nonpharmacologic interventions including joint protection techniques, assistive devices, and thermal modalities, followed by topical analgesics as first-line pharmacologic therapy to minimize cardiovascular risks. 1

Nonpharmacologic Management

• Evaluate the patient's ability to perform activities of daily living (ADLs) and provide appropriate assistive devices to help with mobility and function 1
• Instruct the patient in joint protection techniques to reduce stress on affected joints 1
• Recommend thermal modalities (heat/cold) for pain relief 1
• Consider providing foot splints if the trapeziometacarpal joint is affected, as these may provide symptomatic relief 1
• Encourage regular, low-to-moderate intensity exercise appropriate for the patient's functional status to improve mobility and strength 1, 2
• Consider referral to occupational therapy for instruction on joint protection and prescription of appropriate assistive devices 1

Pharmacologic Management

First-Line Options:

• Begin with topical analgesics rather than oral medications due to the patient's age (>75 years) and hypertension 1, 3
  • Topical NSAIDs are preferred over oral NSAIDs in patients ≥75 years 1
  • Topical capsaicin can be considered as an alternative 1

Second-Line Options (if topicals are insufficient):

• Acetaminophen at appropriate doses is recommended as the initial oral analgesic due to its favorable safety profile in patients with hypertension 3, 4
• If acetaminophen is ineffective, consider low-dose oral NSAIDs with careful monitoring of blood pressure 5
  • Use the lowest effective dose for the shortest duration possible 3
  • Monitor blood pressure regularly, as NSAIDs can interfere with antihypertensive medications 5

Third-Line Options:

• Tramadol may be considered for more severe pain not controlled with the above measures 1, 6
• Avoid opioid analgesics if possible due to increased risk of adverse effects in older adults 1, 6

Special Considerations for Hypertension

• Be aware that NSAIDs can increase blood pressure and potentially reduce the effectiveness of antihypertensive medications 5
• In patients with hypertension, even small drug-induced rises in blood pressure may significantly increase cardiovascular risk if sustained over the long term 5
• When initiating BP-lowering treatment in patients ≥85 years or with moderate-to-severe frailty, long-acting dihydropyridine calcium channel blockers or RAS inhibitors should be considered as first-line agents 1
• Test for orthostatic hypotension before starting or intensifying BP-lowering medication, especially in older adults 1

Treatment Algorithm

1. Start with nonpharmacologic approaches:

   • Joint protection techniques
   • Assistive devices
   • Thermal modalities
   • Appropriate exercise program

2. If pain persists, add pharmacologic therapy in this order:

   • Topical NSAIDs or capsaicin
   • Acetaminophen (if topicals insufficient)
   • Low-dose oral NSAIDs with careful BP monitoring (if acetaminophen insufficient)
   • Tramadol (for severe pain unresponsive to other measures)

3. Monitor regularly for:

   • Pain control and functional improvement
   • Blood pressure changes, especially if using NSAIDs
   • Adverse effects of medications
   • Need for treatment adjustment

Pitfalls and Caveats

• Avoid nondihydropyridine calcium channel blockers (diltiazem, verapamil) in patients with heart failure 1
• Be cautious with alpha-blockers like doxazosin in patients with heart failure 1
• NSAIDs can worsen renal function, especially in older adults with decreased renal reserve 3
• Consider the impact of multiple medications on fall risk in this older patient 1
• Regular follow-up is essential to assess treatment efficacy and adjust therapy as needed 1
