Here are the possible conditions based on your answers:
Patella Fracture
Your kneecap, or patella, connects muscles in your thigh (femur) to your shinbone (tibia). Located at the front of the knee, the patella acts like a shield protecting the knee joint and giving it strength to extend the leg. A patella fracture is a break in the kneecap. It usually results from a fall or a direct blow to the knee.
Read MorePatella Dislocation
Your kneecap, or patella, connects muscles in your thigh (femur) to your shinbone (tibia). When your knee bends, it slides along a groove (femoral groove) at the end of your thigh bone. Patella instability is a condition that occurs when the kneecap comes out of this groove. When this happens, it can result in pain, difficulty walking, and other problems. When the kneecap comes out of the groove a little, but not completely, it is called subluxated. When it moves completely out of the groove, it is dislocated.
Read MorePosterior Cruciate Ligament (PCL) Tears
The posterior cruciate ligament (PCL) is a strong ligament that runs through the center of the knee joint and connects the femur (thigh bone) to the tibia (shin bone). The PCL keeps the shinbone from moving backward after the leg has been straightened. Generally, when a PCL tear occurs, it is partial, meaning that the tear does not go all the way through the ligament. Occasionally, the tear will go completely through the ligament. Partial tears are able to heal on their own, while complete tears may need surgical repair.
