Knee Pain Relief: Immediate First Aid & Care Guide

Acute knee pain often responds to conservative measures. Follow the POLICE principle (updated from RICE).

Immediate Care (First 48–72 Hours)

1. Protection: Avoid aggravating activities. Use crutches if weight-bearing painful.
2. Optimal Loading: Gentle, pain-free movement (quad sets, heel slides) — promotes healing better than strict rest.
3. Ice: 15–20 min every 2–3 hours. Barrier (towel) between ice and skin.
4. Compression: Elastic bandage or sleeve — snug, not constricting. Remove for sleep.
5. Elevation: Knee above heart level when seated/lying.

Medications

• NSAIDs (ibuprofen, naproxen) — oral or topical (diclofenac gel). Use shortest duration.
• Acetaminophen if NSAID contraindicated.

When to See a Doctor

• Inability to bear weight / instability (giving way)
• Significant swelling (rapid, tense)
• Deformity
• Fever + redness/warmth (septic arthritis)
• Locking (mechanical block to extension)
• Pain not improving in 1–2 weeks

Long-Term Management & Prevention

• Physical Therapy: Quad/glute/hamstring strengthening, neuromuscular control, patellar taping, gait training.
• Weight Management: Each 1 lb loss = 4 lb less knee load.
• Footwear: Supportive, activity-appropriate; replace worn shoes.
• Warm-up/Cool-down: Dynamic stretching pre-activity; static post.
• Cross-Training: Low-impact (swim, cycle, elliptical) to maintain cardio.
• Gradual Return: 10% rule — increase load/volume ≤10%/week.

Common diagnoses: PFPS (runner's knee), meniscus tear, ligament sprain (ACL/MCL), osteoarthritis, tendinopathy, bursitis. Treatment is diagnosis-specific.
