Orthopedic surgery is surgery performed by a medical specialist, such as an orthopedist or orthopedic surgeon, trained to deal with problems that develop in the bones, joints, and ligaments of the human body.
Orthopedic surgery corrects problems that arise in the skeleton and its attachments, the ligaments and tendons. It may also deal with some problems of the nervous system, such as those that arise from injury of the spine. These problems can occur at birth, through injury, or as the result of aging. They may be acute, as in injury, or chronic, as in many aging-related problems.
The top 25 most common procedures performed by orthopedic surgeons are as follows:

Knee arthroscopy and meniscectomy
