膝盖用英语怎么说

The English word for "膝盖" is "kneecap". It is a common joint in the body that connects the thigh bone to the lower leg bone. The kneecap helps to cushion and support the weight of the upper body, allowing us to stand and walk. Over time, kneecaps can wear down or become damaged due to injury, age, or other factors. This can lead to pain, swelling, and difficulty moving the knee. Treatment options for damaged kneecaps include rest, ice, compression, elevation (RICE), physical therapy, and in some cases surgery.
