The next morning.

Mr. Wu and his two younger brothers waited for Yang Ping's reply in the family lounge of the general surgery patient.

She was a little apprehensive in her heart, and she didn't know if Professor Yang had a way.

My father had a hard life, and for the sake of his three brothers and sisters, he relied on hard work to earn money, so he sent the three brothers and sisters to college.

I remember when I was in middle school, my father would send living expenses to myself every month, rain or shine, never late, and the monthly living expenses would never be less than the average person, every time I sent living expenses, my father always asked her to be in the park pavilion away from the school, handed over the money to himself, and explained a few words: study hard, and when you grow your body, don't be too thrifty, what difficulties do you have to tell your father, only by reading good books can you be productive, don't believe what the outside says is useless to read, but don't be too stressed, read the book well, Regardless of whether you can be admitted to university or not, it is all beneficial.

Every time, my father never talked about his suffering, but always told her something interesting, as if there was no suffering in his life, only happiness and hope.

Sometimes my father would bring some food, watch himself finish it, and then bring the lunch box back.

Sometimes he would bring some chicken legs, saying that it was because the guests saw that he was working hard to move the goods, and bought them for him to eat, and he was full, so he brought them.

In fact, he knew that it was bought by his father, and what others could afford to eat, he also wanted his daughter to taste it.

Sometimes I will give more money to buy beautiful clothes and skirts, and explain again and again: to earn money is to spend it, don't be too wronged by yourself, as long as you don't waste it, it is normal to wear better clothes and skirts, not extravagance and waste.

When I arrived at university, I could have completed my studies through student loans, but my father said that he had prepared for tuition and did not let himself take out loans.

When she was in college, her father called her every week to chat, telling her to take it one step at a time, not to be poisoned by the messy thoughts in society, and to live her life well.

She understood her father's thoughts at the time, and she was afraid that she would go astray because of poverty and inferiority.

Thinking about it, the corners of Mr. Wu's eyes were moist.

She wanted her father to be happy and healthy in his old age, and she wanted to take her father to travel everywhere.

"Sister?"

The second brother saw that something was wrong with his sister.

"Dad is fine, it's a big deal, let's push a wheelchair and take him out to play."

The younger brother also noticed his sister's expression.

At this time, a doctor came to call them to the meeting room, and Professor Yang asked them to talk to them about their condition.

When he heard Yang Ping say that he could perform knee preservation surgery, Mr. Wu was very excited, which meant that his father could stand up and walk, and he could also visit the great rivers and mountains of the motherland in the future.

---

Old Man Wu was lying on the operating table, and Fat Liang was ready to be anesthetized.

The fat man was amazed that the old man's muscles were better than those of the gym coach, and with his bronzed skin, he showed strength and health, which was obviously inconsistent with the age of seventy-four.

The old man speaks Chongqing dialect, and Liang Fatzi graduated from West China Medical University and can understand the dialect of the Sichuan department.

"Old man, you also make iron? If you don't have ten years of foundation, you can't train this muscle, right? ”

In order to lose weight, Liang Fatzi now goes for a run and goes to the gym to make irons when he has free time.

The old man didn't understand the meaning of iron, but he knew that he was asking him about his muscles, so he stretched out three fingers: "I have been doing it for more than 30 years, and every day I either carry goods or pull a cart, and I have to climb mountains to carry goods." ”

It turns out that this muscle is genuine, and it is shaped by labor.

"Don't just look at this muscle, the old man has cultivated three college students with one flat shoulder." Xiao Wu said next to him.

Liang Fatzi didn't expect the old man to be a ruthless character: "Under the stick, he is a school bully!" ”

However, it is too ruthless to beat with a flat pole, and it is easy to cause problems.

Zhang Lin explained: "It seems that the fat man was beaten a lot when he was a child, and the old man's flat pole was not used to beat people, but to earn money, and he relied on the flat pole to earn money and send three college students." ”

Liang Fatzi was in awe in his heart.

"If you don't study, you can't do it, you have to read, and only by reading can you find a way out."

The old man expressed his ideas in Chongqing dialect.

is really a great father, Xiao Wu Zhang Lin's child is still young, otherwise he really wants to discuss his godson experience with the old man.

In the chat, Liang Fatzi completed the lumbar puncture, implanted the hose, and then pushed the medicine.

The old man felt a hot sensation in his lower limbs, and slowly lost sensation in his lower limbs, as if it were not his own legs.

Hand washing and disinfecting sheets, and the operation began in an orderly manner.

The entire procedure is done minimally invasively.

First, arthroscopy is performed on both knee joints to confirm whether the surgical plan is suitable for the preoperative surgery.

Both knees were explored with arthroscopy, which was completely consistent with the preoperative imaging examination, the cartilage in the medial condyle was missing, and the probe could feel the yellow hard subchondral bone, which was the source of pain, without the protection and cushioning of cartilage, the subchondral bone was directly rubbed and compressed, and the pain nerve could not tolerate this stimulation, so the pain occurred.

The cartilage of the lateral condyle is relatively good, with only mild wear.

There is hyperplasia of the synovium, but there are no obvious symptoms of synovitis.

Yang Ping performed a simple cleaning of both knee joints, arthroscopic transfer to the ankle joint, and the ankle joint was examined, which was also consistent with the preoperative judgment.

All operations are done arthroscopically, using cartilage instruments to remove some cylindrical cartilage on the distal tibia of the ankle joint and above the talus, with cancellous bone underneath the cartilage, this cartilage-bone structure is the most susceptible to healing with the recipient area, and bone healing is always the most reliable.

One by one, the cylindrical cartilage is stuffed into the pre-drilled round hole of the femoral condyle of the knee joint, and slowly, it is put together into a normal condyle shape, and even the curvature is so beautiful.

After the ankle cartilage is removed, the residual cartilage is ground away, the cancellous bone is exposed, and the tibial talar joint is fused together.

The cartilage of the ankle joint is grafted to the knee joint, and the ankle joint is fused.

The so-called joint fusion is to grow the bones composed of joints into one piece, which is equivalent to "welding", to "weld" the joint, all the cartilage must be removed, so that the bone and bone are tightly in contact together, so that the fusion can be achieved.

Because the metal can not be used, the steel plate and the screw can not be used, the means of compression can not be used, the bone bolt is used to connect the two ends of the joint, and then fixed with the absorbable screw, which is also a method, but the absorbable screw is not strong enough to form compression.

The bridging of bone plugs makes up for the regret that it cannot be compressed, so that the joint can grow to one piece without compression.

After the ankle is fused, both lower limbs can still walk, which is no solution.

Osteoarthritis of the ankle joint, long-term chronic pain, joint fusion is a more reliable method, just right, waste utilization, the cartilage of the ankle joint is transplanted to the knee joint, learn from each other's strengths, and solve the problem of the four joints at one time.

Finally, the fibula is amputated in the middle and upper third of the bilateral fibula, and a 3 cm fibula is amputated, so that the parietal column on the outside of the knee joint is dysfunctional, so that the inner and outer sides of the tibial plateau settle evenly.

It's like a house where one side of the foundation collapses and the house tilts, and now the other side of the foundation is artificially collapsed so that the house is straightened again.

For patients with knee osteoarthritis, Academician Zhang Yingze's theory of uneven settlement will achieve good results if used properly.

Academician Zhang Yingze's theory of uneven settlement has opened up a new way of knee preservation surgery, and many knee joints have been preserved in practice.

Yang Ping combined Academician Zhang's knee preservation surgery with autologous cartilage transplantation to successfully solve Mr. Wu's problem.

After the operation, Mr. Wu pushed out of the operating room, and the three sisters and brothers waited at the door of the operating room.

They discussed it properly, and the three siblings took turns to take care of their father during his hospitalization, after all, there was only such an operation in his life, and it was a little uneasy to ask for an escort.

"Dad, are you alright? Does it hurt? ”

The daughter touched her father's forehead very warmly, and the two younger brothers followed behind.

Old Man Wu said with a smile: "I didn't know that I had surgery on my leg, I was dreaming of pulling the cart uphill, but the cart hadn't been pulled up yet, and the doctor woke me up and said that the operation was done." ”

This surgery is a combined spinal-epidural anesthesia, commonly known as semi-anesthesia, and then uses drugs to assist sedation to put the patient to sleep, so that the patient wakes up very awake, unlike general anesthesia and sometimes wakes up confused.

These words caused a burst of laughter from the children, and it seems that the old man is an optimistic and interesting person with a good attitude.

"That slope is relatively long, otherwise why would it take so long?" The daughter was joking.

The old man said: "It's not very long, but I feel that my legs are weak, and I can't pull it all the time, and I'm anxious!" ”

"Both lower limbs are anesthetized, and they must be weak, do you want me to give you some more medicine to let you sleep? Pull the cart up? Liang Fatzi laughed along.

"Don't ---," the old man shook his head.

"Don't shake your head, lie down and don't move." Liang Fat Man pressed his head.

"You are all busy, I can do it myself, you don't have to accompany me, it will delay you too much, and the second child is still coming so far away."

"No matter how far away it is, it's okay, don't worry, we've all arranged a vacation."

The children comforted their father, and the family was happy.
