Conventional patellar fracture will swell badly, unless it is an open injury, emergency surgery is usually not recommended. The reason is that patella fracture, mostly from the front, will lead to skin and soft tissue damage in front, and the surgical incision is just in this position. If there is emergency surgery, it will easily lead to skin necrosis in front of the patella.

Usually we will wait until the swelling begins to subside before elective surgery, usually 5 to 7 days after injury. This will obviously reduce the chances of skin necrosis and blistering.
Of course, this is not absolute. There was some slight collision, but the quadriceps femoris contracted violently. The traction fracture injury can be operated early because the skin injury in front of him is very light.
The topic of the topic is the operation after patella fracture. Kirschner wire Zhang Ligong internal fixation or patellar claw fixation is generally used. Generally, the fracture is relatively stable after fixation. Under anesthesia during operation, we will bend our knees to check the tension later. My patient routinely bends his knees on the second or third day after surgery, requiring him to bend his knees more than 90 degrees within one month. Of course, this will vary from person to person, especially women, who are particularly sensitive to pain, dare not move, and can only do what they can. Old people bend their knees slowly because they are prone to comminuted fractures.
If my patient bends his knees and can reach 130 degrees in a month, I will let him get out of bed early and walk with crutches, and the injured limb will bear 5 to 10 kg. Similarly, all exercises are done step by step and according to one's ability. This is not a formula that applies to everyone.
Patella fracture can be completely healed within 2 to 3 months. After healing, the internal fixation can be taken out about one and a half years. Of course, if you are older and have no obvious discomfort, you can not take it.
