The human body must rely on joints to achieve various sports and exercises, but this does not mean that joints can move freely without restrictions, on the contrary, each joint has its own activity limits, such as the knee joint flexion and extension range is 0-130°, the internal rotation range is 0-30°, and the external rotation range is 0-40°.

However, in daily life, if the maintenance of the knee joint is neglected, the restrictive effect of the patella will be enhanced, hindering the knee joint to achieve a normal range of motion.

"If the member's knee adhesion is adhesion, or has just undergone knee adhesion release surgery, the effect of our patellar release surgery is the best, but remember to pay attention, the technique should be right, and the force should be light!" After explaining the wear and tear of the patella, Ji Ke began to analyze the mobility of the patella, "In fact, the most severely restricted position of the patella is very close to the place where it is worn out, which is where the patella and quadriceps tendons meet. ”

When the technique is loose, the member generally stretches his legs out, and the coach pushes the member's patella to slide in all directions in a slow, gradual and forceful way--- up, down, left, and right, and it is forbidden to slide the patella in an arc!

When the patella reaches the limit of a certain direction, pause for 10 seconds (three to four natural breaths), fully stretch the relevant ligaments and other tissues, and then relax, and continue about 10 times in each direction.

"Remember, never slide back and forth like this, not only is it ineffective, but it also looks extremely unprofessional! If I see someone who does this to the member, 200 at a time is not negotiable!" Ji Ke pushed the patella of the mouse Liu Shuai back and forth quickly, signaling the absolutely forbidden operation. "And you should pay special attention to the angle of force, and try to avoid pressing down!"

Pushing the patella is a relatively horizontal direction, if the angle of force is raised, the patella will be pressed down, so that the patella will be repeatedly rubbed in the trochlear groove, wear down the articular cartilage, just like the patella wear, which is equivalent to the old injury is not healed, and a new injury is added.

"Xiao Ji, I remember that when I push the patella, I can bend my knees, right?" Zhen Peng, who was standing on the side, spoke up, the coach of the gold medal personal training studio, except for Ji Ke, is the highest level of rehabilitation for him, and he has a deep impression of the rehabilitation actions of various parts.

"Yes, but if the technique is not skilled enough, the experience is not rich enough, don't let the members bend their knees to cooperate, not to mention the difficulty, the requirements for the coach are also high, we are estimated to be fine, if there are newcomers in the future, you don't teach them!"

Members bend their knees to cooperate, not only because of the difficulty of operation and the experience of coaches, but also because of whether the member's condition is suitable for bending the knees; Ji Ke is very worried that those inexperienced coaches can't control their eagerness to achieve results, and let the members cooperate regardless of the risk.

"Okay, the patella is fine, right? If there is a problem, just say, let's solve it on the spot, if it's okay, then I'll ......."

"You wait a minute, don't you see that we are remembering?!" A group of friends who were struggling to write and record the main points immediately interrupted Ji Ke, this time was the critical moment for them to combine what they had learned and integrate the patella treatment techniques, but they didn't want to be disturbed by Ji Ke.

Ji Ke was not in a hurry, it was estimated that they would have a long time before they stopped, so they set off to the front desk to bring the small teapot and paper cups, and the explanation of the knee joint could not be finished for a while, and there were not many people at noon, so they could talk about it well.

After a few people took notes and drank water, Ji Ke began to explain the next step.

"Knee pain mainly occurs in two parts: patella, meniscus; patella has been said almost, let's start talking about meniscus," Zheng Shi in the twilight summer is still dry and hot, Liu Shuai, who is wearing breeches, pulls up his trouser legs, exposes his knees, and continues to act as a guinea pig--- In order to balance the diary situation and the image of the coach and the studio, Ji Ke prohibits male coaches from wearing shorts to work, at most wearing breeches.

Cartilage has an important role in bearing loads in the human body and reducing inter-articular bone friction, and belongs to dense connective tissue, which is roughly divided into three categories: hyaline cartilage, elastic cartilage, and fibrocartilage.

Fibrocartilage is distributed in many places in the human body, mainly in the intervertebral disc, pubic symphysis and knee joint!

"The meniscus and the annulus fibrous cartilage are both fibrocartilage, so from this point on, you should know that once the meniscus is damaged, it is almost a permanent injury, and the chance of recovery is quite slim, and all we can do is relieve the pain caused by the injury. ”

Ji Ke gave his friends a preventive shot in advance, lest they boast about Haikou and say that he could cure the meniscus injury, although he did can, but he also prepared an excuse for not packing tickets with good technology and a relatively small probability of recurrence.

Ji Ke didn't dare to blatantly claim that he could solve the medical problem, it wasn't the lice on the monk's head -- it was clearly saying that he had a problem!

Meniscus As the name suggests, it has a crescent-shaped shape, and each knee joint has two meniscus inside and outside;

The end of the femur of the thigh is composed of two protrusions, which are called the lateral femoral malleolus and the medial femoral malleolus (HUAI), collectively referred to as the femoral malleolus;

The meniscus on either side of the knee supports the medial and medial malleolus of the femur, while the meniscus that carries the femoral malleolus lies on the platform at the top of the tibia, the tibial plateau.

"The way to detect whether the meniscus is injured is very simple, that is, through the internal and external rotation of the knee joint. Ji Ke grabbed Liu Shuai's foot with one hand and pressed the other hand on the position of the front end of his tibia below his knee joint.

"First bend the leg to be examined, hold the position of the tibial tuberosity to stabilize the calf, and then adduct and externally rotate the calf and then straighten the knee joint, this is the way to check the medial meniscus!"

"Abduction and internal rotation of the lower leg and then straightening the knee are the way to examine the lateral meniscus. ”

"Once we have detected the location of the meniscus damage, we need to tell the extent of the damage, and I will tell you more about the types of meniscus. Ji Ke paused slightly, leaving time for the friends to react and record.

The meniscus is connected to multiple ligaments and bone features, and the places where wear and tear occur are naturally diverse, such as lateral injury, anterior and posterior angle injury, longitudinal and transverse injury, horizontal plane splitting, longitudinal breakage, lateral expansion injury, relaxation of meniscus attachment points, and a series of injuries.

It can be said that the meniscus can only be said to be unimaginable in terms of injury, and no meniscus cannot be done!
