1. The knee is a hinge joint. Its movements are flexion and extension.

2. The muscle groups that are the most important in flexion and extension of the knee are the quadriceps and the hamstrings. The hamstrings are responsible for flexion of the knee. These muscles include the biceps femoris, semitendinosus and the semimembranosus. The quadriceps are responsible for the extension of the knee. These muscles include the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius.

3. When muscle and bone tissues are not used they weaken and atrophy .When one doesn’t use their muscles or bones there isn’t as much blood being supplied to those areas and leaving less nutrients. The result is they decrease in size and strength.

4. Both tendons and ligaments are made of dense regular connective tissue which is made up of collagen fibers, fibroblasts and ground substance. With tendons and ligaments being composed primarily of the same tissue components, a tendon can be used to replace a torn ligament.

5. The knee joint is a synovial joint lined with a synovial membrane. It is filled with fluid to support friction. In order to operate on the menisci or ACL the synovial membrane would need to be severed.
