In general, a toaster oven will preheat to temperature quicker than a conventional oven because of its smaller size. It will also hold the temperature better for the same reason. Cooking with a toaster oven saves time over using a conventional oven.
How to Treat Knee Hyperextension. A visit to the doctor to ensure that the ligaments and cartilage in your knee are intact is recommended. For minor knee hyperextension, RICE (rest, ice, compression, and elevation) for 2-4 weeks will allow the knee enough time to heal.
In brief: Injured by extension. Hyperextension means over-extension, or straightening a knee joint beyond the straight position. If one straightens out his leg, it stops approximately straight, which is normal. If his lower leg and foot continues moving past the straight point, that is called hyperextension. At first, knee ligaments will over-stretch, with a little bleeding. Further extension will tear up the ligaments.
