The knee is made up of three bones. These are:
These bones are held in place by four main ligaments. These are:
The anterior cruciate ligament is situated diagonally in the middle of the knee. It helps to keep the tibia in place, and prevents it from sliding in front of the femur. The anterior cruciate ligament is essential for stability in the knee.
The anterior cruciate ligament can be damaged in the following ways:
Symptoms of an injury include:
During an anterior cruciate ligament reconstruction procedure, your orthopedic surgeon will rebuild the injured ligament. This is generally done by replacing the damaged ligament with a tissue graft on which a new ligament can grow.
This type of procedure is performed arthroscopically. During arthroscopy your orthopedic surgeon will insert a camera into your joint. Images will then be displayed on screens for him see as he works with small surgical tools. The surgical equipment used in arthroscopy is particularly small, which means that the incisions made in the body will be small, less painful, and will heal much quicker than those made in traditional open surgery.
Recovery will depend on the severity of your injury, as well as your personal condition. Speak to your orthopedic surgeon about rehabilitation, physical therapy, and any lifestyle changes that might be required.
