What to avoid in first 3 months after hip or knee replacement

In the first 3 months after hip or knee replacement, avoiding certain movements and habits protects the new joint, prevents dislocation, and speeds healing. Dr. Shreyas Zalariya’s patients follow these evidence-based precautions alongside personalized rehab for optimal results.

Critical Avoidances for Hip Replacement

Focus on hip precautions (especially posterior approach) to avoid dislocation:

• Crossing legs at knees or ankles.
• Bending hip beyond 90° (e.g., low chairs, picking up objects from floor while seated).
• Lifting knee higher than hip or leaning forward excessively.
• Twisting torso or feet inward/outward deeply.
• High-impact activities like running, jumping, or heavy lifting.

Critical Avoidances for Knee Replacement

Prevent strain and falls while building strength:

• Crossing legs or kneeling.
• Sitting in low/soft chairs or prolonged sitting (>45-60 mins without moving).
• High-impact sports, twisting motions, or activities risking falls (ladders, slippery surfaces).
• Heavy weight-bearing too soon or skipping physio.
• Unsuitable shoes (flimsy, no support).

Shared Precautions (Both Joints)

• Submerging in water (baths, pools, jacuzzis) until 6 weeks.
• Ignoring pain/swelling—report signs of infection (redness, fever).
• Smoking, poor diet (low protein), or overdoing early activity.
• Driving until cleared (typically 4-6 weeks).

Hip vs. Knee Avoidance Comparison

Category	Hip Replacement ​	Knee Replacement ​
Positions	No leg crossing, >90° bend, knee above hip	No crossing legs, low seats, kneeling
Activities	Twisting, floor reaching, high-impact	Prolonged sitting, falls risk, twisting/jumping
Daily Habits	Low toilets/chairs initially	Unsupportive shoes, skipping exercises
Duration Focus	Strict first 6-8 weeks	Gradual first 3 months
