Chen Yu didn’t rush to answer, asking a question of his own instead.

"Dr. Wolffat, I’ve read in the media that you’re also an expert in human anatomy. It’s said you can usually determine a player’s injury just by a physical examination. How do you do that?"

Just as Wolffat had researched him, Chen Yu had also looked into this famous Bayern miracle doctor who was renowned throughout Europe.

The media had reported that Wolffat could pinpoint which area of a player’s body was injured just by using his hands in a physical exam. He could even be precise enough to identify the specific muscle, the degree of tearing, and whether there was any fluid buildup.

’This is actually quite incredible,’ Chen Yu thought, rather curious himself.

Wolffat gave an embarrassed smile. He thought Chen Yu was just being modest, but he felt honored to have the opportunity to explain his techniques, especially in front of a world-class, top-tier doctor like Chen Yu.

"May I?" Wolffat stepped forward.

Chen Yu nodded and stepped aside.

Wolffat had Ballack lie down on the bed and then began to explain his physical examination experience.

"For example, I first use my fingers to feel the muscle tension. Then, I press and palpate both longitudinally and transversely. By asking the patient questions, I can determine the central point of pain, then determine the depth of the pain, and finally locate the lesion."

"Then there’s the fascia. The muscle surface is covered by fascia. A fascial rupture can be felt by touch. If it isn’t smooth and flat, it has likely torn. If it’s smooth but feels tight, it’s probably muscle hardening that needs to be relieved."

"Oh, and fluid buildup. After an injury, fluid usually accumulates between the fascia and the muscle. You can’t see it from the outside, but if you feel a slippery, soap-like sensation when you touch it, there’s a high probability of fluid buildup."

He put his hands to work, touching Ballack’s ankle as he explained his experience. He could recite the locations of the ligaments, muscles, and tendon sheaths of the ankle as if listing his family heirlooms.

Chen Yu nodded to himself.

’No wonder this guy’s a miracle doctor. He’s the real deal.’

’This kind of skill requires an incredible wealth of anatomical and clinical experience. Otherwise, how could you possibly detect an injury through such subtle changes in texture?’

And it wasn’t just for show.

This technique was extremely useful. After a player suffered an unexpected injury, a physical exam could immediately determine the location of the injury, allowing for targeted treatment on the spot. This was also greatly beneficial for subsequent treatment when the player was sent to the hospital for scans.

’In this respect, I’ve really benefited from the Eye of All-Seeing. Without it, I might not be able to reach Wolffat’s level.’

"This is the experience I’ve accumulated over many years of work." Wolffat stopped.

Before Chen Yu could speak, applause broke out beside them.

Turning his head, he saw it was Kawajiri Kensaku, clapping excitedly and nodding repeatedly.

The two assistants behind him hurriedly joined in the applause.

But they quickly realized no one else was clapping, and their faces twitched with embarrassment.

"I just thought Dr. Wolffat’s explanation was excellent. I learned a great deal," he explained awkwardly when he saw everyone looking at him.

Although he wasn’t an orthopedic specialist, as a surgeon, he often had to perform physical exams on patients. To be able to conduct an exam at Wolffat’s level was, in his opinion, simply incredible.

’He must sleep with an anatomical model every night to understand the human body to this degree.’

Wolffat smiled graciously and said, "It’s just some clinical experience, that’s all."

He paused, then looked at Chen Yu and added, "But Dr. Chen is far more skilled than I am."

Chen Yu shook his head. "Actually, my method is quite similar to yours. I also use subtle changes in texture to confirm the extent of damage to the affected area. It’s the same during physical therapy and massage—I adjust the pressure and technique based on the body’s feedback. I just incorporate some things related to acupoints."

At the mention of acupoints, Kawajiri Kensaku’s eyes lit up, and he subconsciously exclaimed, "Acupoints! I know about those."

Influenced by traditional Chinese medicine, of course he knew about acupoints.

Chen Yu nodded and pointed to Ballack’s right ankle. "He has a few problems right now. First, a strain of the anterior talofibular ligament."

The anterior talofibular ligament is located in the hollow of the ankle.

It’s short and fragile, making it the most easily injured part of the ankle joint after an external twisting force or impact.

However, it provides at least sixty percent of the ankle’s stability, making it the most important ligament. An injury to it is not only difficult to heal, but the reduced strength after healing can also lead to recurring ankle sprains.

Many professional athletes who frequently sprain their ankles most likely have a problem in this area.

"In fact, he has trigger points on the outside of his ankle and the outside of his lower leg. This should be damage to the peroneus longus and brevis muscles. Combined with recurring sprains that haven’t healed properly and playing through injury, inflammation and fluid buildup have already occurred."

To put it bluntly, after spraining his ankle, he didn’t rest well enough or long enough. He returned to play, sprained it again, and ended up in this state where it looks healed but still hurts.

If it hadn’t quite turned a minor injury into a major one, it was close.

Actually, in Ballack’s situation, if it weren’t for the World Cup and he had the offseason to rest for a whole Summer, he would basically be fine.

But with the World Cup now, and him needing to play, the situation was rather tricky.

Wolffat nodded repeatedly, shocked.

’He’s definitely an expert. He knows what’s wrong with a single touch.’

Keep in mind, Chen Yu hadn’t even looked at Ballack’s medical records before the exam. Yet the diagnosis he gave was identical to the results of the previous MRI scan, with no difference whatsoever.

"Chen, you are much more skilled than I am." Wolffat couldn’t help but give a thumbs-up.

Beside them, Kawajiri Kensaku instinctively started to clap but forced himself to stop. Inwardly, however, he was nodding nonstop. ’These guys... they really are masters, world-class doctors.’

"Chen, is there a way to treat it?" Wolle couldn’t help but interject.

He didn’t really care how it was diagnosed; he just wanted to know if it could be fixed.

Wolffat also looked toward Chen Yu.

His own recommendation to the team had been for Ballack to rest for one match and play in the second game of the group stage.

But Ballack was the core of Germany’s midfield, and Wolle was reluctant to bench him. He also wanted to use the group stage to fine-tune the lineup.

Chen Yu nodded. As he opened his portable medical kit, he asked Wolffat how he would handle such a situation.

It was an exchange, after all, and Chen Yu was quite curious about how Wolffat would treat it.

’When it comes to medical skills, you have to keep learning and exchanging ideas.’

For example, his recent trip to China had been immensely beneficial.

Wolffat sighed, glanced subtly at Wolle, and said, "If it were up to me, I would focus on physical therapy and massage, supplemented with some medication and subcutaneous injections."

At the mention of subcutaneous injections, Wolffat perked up and explained that this was his proprietary therapy.

"I use local injections. I inject various extracts I’ve developed myself into the pressure points, adhesions, and areas of inflammation. For example, substances from rooster combs, deproteinized calf blood extract—also known as Actovegin—or other natural plant extracts."

"The main purpose of doing this is to use these various substances to promote local blood circulation and metabolism."

Chen Yu was stunned.

’I don’t really know the medical regulations here in Europe, but developing your own extracts and injecting them into patients? In the United States, you’d have been arrested long ago.’

’This is tantamount to treating a patient directly with drugs that haven’t undergone clinical trials.’

’Aside from Actovegin, the rest—rooster comb extract, plant extracts—what on earth is all this? None of it has been through rigorous clinical trials. Aren’t you afraid something will go wrong?’

Chen Yu knew that some "God therapies" were popular in Europe, where blood was drawn from a person, processed, and then reinjected. It wasn’t that it didn’t work—modern medical research has shown it has some effect, which is how PRP therapy was developed.

’But why are they so obsessed with blood? It’s like the bloodletting therapies of the Middle Ages.’

"Actually, the therapeutic effect you’re describing can be achieved through other methods," Chen Yu said after a moment’s hesitation.

After hearing him out, Chen Yu had a general understanding of Wolffat’s treatment philosophy.

He had a deep knowledge of human anatomy and followed the principle of treating the problem at its source. The most direct way to do that was to inject medication directly into the affected area.

Putting aside his various proprietary extracts, the ultimate goal was simply to control local inflammation and accelerate blood circulation in the affected area to achieve a therapeutic effect.

’In that case, isn’t that just Acupuncture?’

Acupuncture stimulates acupoints and meridians to accelerate blood circulation and metabolism, activating the body’s immune system to achieve self-healing.

That’s right, self-healing, not curing.

At least eighty percent of human ailments are self-healed; many drugs only play a supporting role.

From that perspective, the principle behind his treatment was sound.

’It’s just that the risks are a bit high. It could be completely replaced by Acupuncture.’

"What method?" Wolffat was slightly taken aback.

Chen Yu didn’t explain right away, instead taking out a Small Needle Knife.

"When I deal with adhesions caused by inflammation, I usually use this method called a Small Needle Knife. The effect is very good." Chen Yu showed the Small Needle Knife to Wolffat, then directly administered a local anesthetic to Ballack.

"Look, he has an adhesion here on his lateral malleolus. You should be able to feel it."

Chen Yu pointed to a spot.

Wolffat felt it and nodded.

It was a myofascial adhesion caused by inflammation. Normally, one would first control the inflammation and then slowly release it with physical therapy and massage.

But now, Chen Yu was going straight in with the needle.

Under the Eye of All-Seeing, Chen Yu slightly twirled the Small Needle Knife in his hand. Its sharp blade broke through the adhesion point, achieving the effect of releasing the muscle.

Thanks to the anesthetic, Ballack felt no pain. He just watched Chen Yu work with curiosity. He had heard from Scholl and Desler that Chen Yu liked to stick them with needles.

After a short while, Chen Yu stopped and let Wolffat feel the area again.

"The adhesion is gone?" Wolffat touched the spot and was instantly stunned.

The feeling of muscle adhesion is like Velcro; the texture is rough, lacking that smooth sensation.

But now, the spot that had felt rough before was gone.

"This is incredible! How did you do that?" Wolffat’s face was filled with shock.

He had noticed the blade-like structure on the tip of the Small Needle Knife, but working through the skin and flesh, he couldn’t see the internal adhesion. How could one precisely sever the adhesion without damaging other healthy tissue? The whole process was simply baffling.

Chen Yu smiled. ’Don’t ask. The answer is simply that I understand human anatomy.’
