- Kneecap fracture, or patellar fracture is a break in the kneecap or patella. The kneecap is a small bone located at the front of the knee, at the joint of the femur bone of the thigh and tibia and fibula, the two bones of the lower leg.
- Patella also connects the muscles in front of the thigh to the bone of the lower leg, tibia. Patella serves as a shield to the knee joint and injury to patella is a serious condition that affects the straightening of the knee and walking.
- Fracture of the patella can be a simple breaking of the bone into two pieces or be a complicated one of the bone breaking into several pieces.
- Kneecap fractures that are simple, can be treated by wearing a cast or splint for the bone to heal properly. Injury can also cause the bone to move out of place, which can be corrected only by surgery so that the joint can be restored, stabilized and the function returns.
- Kneecap fracture typically occurs due to a hard hit on the knee, either by a fall or by hitting the knee with something hard. Swelling, pain, bruising and inability to move the knee are the symptoms of kneecap fracture.
- A painful defect like dislocation of the bulge of the knee-joint may be observed. Sometimes blood can be detected in the joint. If left untreated, the pain increases and becomes intolerable. Further, the dislocation of the patella can rub against the bones tibia, fibula or femur, causing them injury and damage.
Types of kneecap fracture:
- Stable fracture: The bone is not displaced from its original place. The broken pieces may remain in contact with each other or may be separated just by a millimeter or two. While healing too, the bones stay in place.
- Displaced fracture: The broken ends of the bone get separated and do not align back correctly. Disruption of the smooth joint surface also occurs
