The muscles in a leg are used to straighten it. They lengthen and contract to move and control leg movement, including straightening.
Basically, quadriceps are used to extend the lower leg to straighten it.
No, you should not straighten your leg after a knee subluxation as this action could further hurt your knee joint.

A kind of elastic tissue
When you straighten out your leg your tendons are tighter, and then there is your patella disabling you from doing that

Ummm I think chicken legs :P
The heaviest muscle in the human body is the gluteus maximus. It serves to straighten the leg at the hip during walking by extending the thigh backward.
The muscles used to straighten the leg are commonly known as the Quadriceps, a group of four muscles on the front of the thigh. This, however, is only the cast when the knee is isolated. If you were to stand up from a squatted position, you would also be using your gluteal muscles as well as your hamstrings to extend the thigh and stabilize the knee, while your quads and inner thigh muscles (the adductor) help to straighten the the knee. You would also be using your calf muscles to straighten the ankle.
tendons
To "extend" the knee joint means to straighten the leg by increasing the angle between the thigh and the lower leg. This movement is performed by contracting the quadriceps muscles on the front of the thigh, which pull on the patellar tendon to straighten the knee.
Have it checked by a vet. It's possible the calf just broke his leg and it needs to be straightened out and put in a cast to get it to grow normally again.
