The surgery is scheduled on Monday, and there are two days on Saturday and Sunday to prepare for the operation, and after explaining the exact time to the patient who will have surgery on Monday, you can go to the operating room.

When Lu Cheng rushed to the operating room, the first one had already begun.

Today's two larger surgeries are total knee replacements, both scheduled for the morning.

There are a lot of people on the stage, Professor Min is the main knife, Lin You is supporting his legs, Suzaku Guang is helping, and the doctor in charge of the bed is pulling the hook.

There were also six people in total, plus a nurse who washed her hands, and seven people surrounded the operating table.

The first surgery was from a plastic surgery department, but she basically didn't have anything to do, just occasionally passed the instruments.

Shi Ding and Chen Hui are also doing hook work.

It's kind of a job to do its job.

Lu Cheng looked at the timing of the operation, and it had been more than twenty minutes since it had been carried out, but the femoral osteotomy had been completed, and only the tibial platform was left, and the time was very fast.

Although knee replacement surgery is a quick operation, it is actually much more difficult than a hip joint.

But this kind of difficulty, in the hands of Professor Min, definitely does not exist.

Lu Cheng continued to look at the tibial osteotomy.

There is still a lot to learn from a tibial osteotomy.

For example, Professor Min likes to cut out the posterior cruciate ligament and do posterior stabilization.

However, Lu Cheng has also seen in the literature that some people will keep the posterior cruciate ligament and make a posterior cruciate ligament preservation prosthesis.

It's certainly a matter of personal habits.

In fact, so far, there has been no prognostic difference between posterior stable and posterior cruciate ligament-sparing prostheses.

However, there are many options for implants.

It takes too much experience and understanding for each doctor.

Being a doctor is very simple, can endorse, and has a solid basic knowledge, so you can see a doctor.

Well, yes, it's a doctor.

But in fact, it is very difficult to be a doctor, because so far, no disease can be completely treated until the onset of the disease.

Even if a child's fracture can be completely healed, in fact, after healing, there is still a certain difference in the strength and range of motion between the two sides.

It can only be seen how each person understands the cure.

That's why medicine has no end at all.

The more I experience it, the more scared I become, the more I feel small, and I always feel that every step I take is not perfect enough.

But this is a limitation of the entire medical environment, and it has nothing to do with itself.

That's where the frustration lies.

Lu Cheng remembers that when he was an undergraduate, a teacher said a sentence.

Learn, learn, learn.

Learning is the only way we can learn more about the world and make ourselves less ignorant, which is good for both people and ourselves.

That's all.

Let's go ahead and see the surgery.

Professor Min is used to cutting out the posterior cruciate ligament, and he must want to make a posterior stable prosthesis.

However, in addition to the post-stable type, there is also a distinction between single radius and multiple radius.

I don't know what Professor Min will think.

Just as he was thinking about it, Professor Min suddenly began to point: "The difficulty of knee surgery is instability, so the focus of this operation is that the osteotomy of the tibial platform and femoral platform must be done." ”

"As long as the line of force and the joint surface are controlled within a controllable range, then this operation is almost complete. ”

"This is the outline of knee surgery, whether it's varus knee, valgus knee, complex knee replacement. ”

"But if there is a fracture of the tibia and femur combined, it is a different category......"

The knee joint is where the femur and tibia meet, and where the thigh and calf connect in the middle, behind the kneecap.

With Professor Min's words, Lu Cheng's knowledge outline was constantly filled.

Moreover, Professor Min is worthy of the level of a professor, and what he said was neither deep nor shallow, leaving room for comprehension and experience, but he did not directly explain it thoroughly.

Only when it is really at a level where it can be taught, it is called a professor.

Otherwise, it's the director and deputy director.

You can also be called an expert, but you can't be a professor.

It is certainly not wrong to refer to professors as experts, but on the contrary, it is not necessarily appropriate.

……

An operation, and it was over in a hurry.

The surgery was a success, of course.

Both knee joints are of equal length, there is no instability, and because of the installation of knee prostheses, the pain of the knee joint after surgery can be greatly relieved, or even completely relieved.

This is the current level, the best surgery can be done, it can be taken out, there is nothing wrong, but there are no special highlights.

After watching the operation, Lu Cheng asked himself in his heart.

Is there room for improvement?

Lu Cheng thought in his heart for a while.

Yes, definitely.

Where's it?

In many places, even each step of processing, it has the potential to become room for improvement.

But which step is it and how to change it?

Lu Cheng couldn't think of it.

But how to change it, Lu Cheng has thought about it in his heart, but it still needs to be verified more systematically.

There are too many ways to treat them, and depending on personal experience, the way of medication will not be the same.

It is not said that the medication and surgery methods of the two doctors are exactly the same, and they are completely similar.

Even the common cold, too.

If you really want to change it, you can definitely change it.

If you can't, you can only say that you don't have a deep experience......

The second knee replacement was originally from Senior Brother Zhuoyuan.

But Senior Brother Zhuoyuan was 'assigned' to write articles, so Lu Cheng naturally operated on him.

Anesthesia, sterilization, drape.

Under Lin You's reprimand, Lu Cheng was finally able to complete it in a very standardized manner.

It's not skilled, after all, it's only been half a month, but it's standardized.

Specification is what surgery must pursue, and then surgery.

After the stage opened, Lin You said: "Professor Min, I have cut the skin, you can wash your hands and get dressed." ”

"Okay, you and the little finch will go in first, tour, tranexamic acid and cefuroxime drops, right?"

"Dripped. ”

"Okay, prepare the instruments, we'll do this operation more smoothly. ”

Professor Min walked out.

Lu Cheng quickly walked to the opposite side of Lin Youdi, took the tweezers and suction device in his hand, and at the same time held the gauze in his hand to stop the bleeding and expose the field.

After glancing at Lu Cheng, Lin You suddenly asked again: "Is there a difference in the clinical prognosis between the medial and lateral approaches of knee replacement?"

"Not yet. ”

"Well, but we're used to the medial approach. ”

As the surgery progresses, the surgical field is further peeled off.

Lu Cheng began to speak: "Teacher, give me a nail hook." ”

"Teacher, give me a middle bend. ”

"Teacher, bone knife. ”

“……”

The more he shouted, Lu Cheng seemed to be immersed in it.

"Femoral osteotomy. ”

"Nails. ”

"Slip hammer. ”

"Putting it in place. ”

"It's time to adjust the cement. ”

I don't know if Lu Cheng spoke too fast, but in addition to Lu Cheng speaking on the stage, Professor Min said. Suzaku Guang and Lin You and the others didn't speak anymore.

Even in the end, the prostheses of the tibia and femur were installed, and Lu Cheng realized that just now he had actually instructed his master to adjust the bone cement.

Frightened, he hurriedly put down the stitches in his hand, and then said to Lin You, who was standing outside the operating table, standing farther away than washing his hands: "Master, you can close the wound, come on." ”

The heart is so weak that I can tell you all.

Lin You took off his gloves directly with both hands, untied the surgical gown with both hands, and sneered: "You want to be lazy, you want to be beautiful." ”

"Your master has been stitching up his wounds for three years, so stay on the stage honestly for me. ”

"This surgery is five minutes earlier than the previous one, and you can be stitched vigorously and slowly. ”

Lin You looked like I wanted to go, and only then did he say another sentence after getting off the stage: "Brother Ding, Brother Hui, you look at it." ”

"Don't worry, Brother You, Xiao Lu is definitely a good player. We can all take more rest. The two didn't get off the stage, but they also looked like they were watching the show, and they didn't mean to sew it themselves.

Lu Cheng buried his head and began to sew.

The suture of the knee joint is not simple, but as long as you grasp a good concept and ensure that each layer is docked to achieve soft tissue balance, the prognosis will not be very bad.

With this as the foundation, Lu Chengcheng began to start......

It's just that intentionally or unintentionally, the tour suddenly said: "Today's surgery is the same as the previous one, why is it suddenly over five minutes early?"

There was no response to this voice, but everyone looked at Lu Cheng who was stitched.

Lu Cheng felt that more than one eye was searching for him, so he could only pretend not to know.

He knew that he had a bit of a good time today, and a little overstepped.

However, it seems to have worked well......

At this time, it can only be more cheeky.

I don't listen, I don't listen.

I can't hear anything, I'm just a stitcher, don't look at me.
