The knee joint plays a key role in daily activities. The cruciate ligaments of the knee are the two most important ligaments responsible for maintaining the stability of the knee joint. Usually when the anterior cruciate ligament is injured, the swelling and pain are obvious, while the deeper posterior cruciate ligament strain is easier to ignore in the early stage. It is not until the cumulative wear and tear becomes serious that the knee joint loosens and causes inflammation and pain.
Posterior cruciate ligament stabilizes the knee. Common problems are mostly chronic strains.

It is mainly to prevent the lower leg from moving backward, so that the upper and lower legs can be joined and stabilized without loosening and separation. Such as providing support when running and stopping suddenly, etc.
Acute posterior cruciate ligament injuries usually occur when there is an external impact. For example, in a car accident, the calf directly hits the front fender of a motorcycle. The strong impact force causes the leg to bend backwards, which may pull the posterior cruciate ligament and cause direct rupture. In severe cases, it may even require Surgical reconstruction. However, in comparison, chronic posterior cruciate ligament strain that has accumulated over a long period of time is actually more common clinically.
Category 3 groups with chronic posterior cruciate ligament injuries should be more careful
When walking down stairs, the back foot is supported by the posterior cruciate ligament, which prevents the calf from moving backward even if the ground reaction force occurs. However, if these movements are too frequent, it can easily lead to excessive strain on the posterior cruciate ligament, leading to chronic injuries.
In addition, for people with a beer belly or an anterior tilt of the lumbar pelvis when viewed from the side, the weight and angle of the abdomen are too large, causing the lumbar spine to protrude, which inadvertently pulls the pelvis forward. At this time, the knees must also exert force backward to compensate. .
Furthermore, wearing high heels will have the action of stepping on the toes, which will also force the knees backward. Over time, chronic damage will occur.
Pain when bending the knee is a warning sign!prolotherapy accelerated treatment
When stretched, the posterior cruciate ligament is like a tight rubber band. In the long run, it is likely to cause strain or deformation, eventually causing pain and discomfort, or causing knee instability.
Therefore, if your knees feel tight and stiff, and you feel unstable or painful when you squat and bend your knees to the end, such as kneeling on a tatami or going down stairs and need to bend your knees, you may have a posterior cruciate ligament injury. warning.
Dr. Cai Yunzheng pointed out that because tendon and ligament repair takes a long time, it will take at least more than 3 months to achieve significant improvement with traditional rehabilitation treatment. If you want to speed up the recovery process of the posterior cruciate ligament, you may wish to consider using prolotherapy, which can significantly shorten the recovery time. Time consuming. Proliferative therapy includes initial high-concentration glucose solution, high-concentration platelet plasma (PRP) and platelet freeze crystal (PLT). You can choose the appropriate therapy according to your own needs.
Among them, platelet frozen crystal is a new type of platelet preparation. With only one blood draw, you can get multiple bottles of extracted platelet powder, which can be used in fixed doses and in batches to improve treatment efficiency.
Strengthen the core and quadriceps muscles to maintain posture and reduce the burden on the posterior cruciate ligament
After prolotherapy, you should still pay attention to not bending your knees too much. For example, avoid bending your knees frequently, don’t wear high heels, lose weight, eliminate your beer belly, and avoid forward pelvic tilt. Dr. Cai Yunzheng reminds that strengthening training of core muscles can make the pelvis better. Lean back to reduce load on the posterior cruciate ligament.
In addition, the muscles around the knee, the quadriceps, have good stability and can also share the force of the posterior cruciate ligament. It is recommended that professional coaches or physical therapists guide you in correct training movements to avoid injury.
