What Are the Signs of a Broken Kneecap?
Fractures of the sacrum are more common injuries, which are mainly manifested by local swelling and pain of the sacrum, inability to straighten the knee joint, subcutaneous bruising and abrasions of the knee skin. The age of patella fractures is generally between 20 and 50 years old, with more men than women, about 2: 1.

Causes of patella fractures
- Fractures are caused by direct and indirect violence.
Clinical manifestations of patella fractures
- After sacrum fracture, there is a large amount of blood in the joints, congestion and swelling in the subcutaneous area of the anterior sacrum, and in severe cases, blisters may occur on the skin. The knee joint is severely painful during exercise, and bone rubbing can sometimes be felt. There is a displaced fracture that can touch the fracture line space.
Patella fracture examination
- Imaging findings: Translucent or star-shaped X-ray translucent fracture lines can be seen in the sacrum. Due to the involvement of the quadriceps tendon and the patellar tendon, the fractures are more separated, and the upper segment of the fracture is displaced upward, but the lower segment is not displaced. If the quadriceps tendon is not completely broken, fracture displacement is rare.
Diagnosis of patella fracture
- X-ray of the metatarsal bone can be diagnosed. Suspected longitudinal or marginal fractures of the patella should be confirmed by radiographs.
Treatment of patella fractures
- Treatment of patella fractures should restore the smoothness of the articular surface to the greatest extent, and provide a relatively strong internal fixation and early movement of the knee joint to prevent the occurrence of traumatic arthritis.
- Non-surgical treatment
- Plaster support or cast fixation is suitable for non-displaced patella fractures, without manual reduction, withdrawing blood from the joints, bandaging, and long-leg cast support or cast fixation of the affected limb in the extended position for 3 to 4 weeks. Exercise quadriceps contraction during plaster fixation and knee flexion and extension after removing the plaster cast.
- 2. Surgical treatment
- Metatarsal fractures are displaced by more than 2 to 3 millimeters, articular surface unevenness is more than 2 millimeters, and laceration fractures of the extensor support belt are best treated with surgery.
