Why Dry Ice Can Damage Your Knee Joint
Dry ice holds –78 °C; chondrocytes start dying below –10 °C, risking permanent joint damage and slower rehab. Orthopedic guidelines recommend 10 °C–15 °C surface cooling for 15–20 minutes to curb inflammation safely.
| Contact Temp | Safe Duration | Resultado |
|---|---|---|
| 15 °C–10 °C | 15–20 min | Reduces edema & dolor |
| 5 ° C | < 10 min | Numbing, mild burn risk |
| –10 ° C | < 1 min | Capillary damage |
| –78 ° C (Seca) | < 5s | Deep frostbite, cartilage death |
