Why is my knee giving way?
What is the meniscus? And how do complaints come about?
The menisci are crescent-shaped cartilages in our knee joint and lie between the bones of the thigh and shin. There they absorb shocks and distribute the weight of the body evenly over the joint. A distinction is made between the inner and outer meniscus.
Meniscus pain usually occurs in one Overuse of our knee joint caused by a twisting of the bent knee. This twisting usually happens in sports where the knee has to absorb and control abrupt turns, stops and starts - such as sports. B. skiing. But also long kneeling on the floor, such as laying when flowing, can cause discomfort in the meniscus. The inner meniscus is more often affected because it is less elastic. As we age, the cartilage in our knee becomes increasingly brittle, which means that the menisci can tear more easily.
What is the cruciate ligament? And how do complaints come about?
The Cruciate ligaments form together with the Inner and outer band the ligaments of the knee and are responsible for stabilizing our knee joint. The name "cruciate ligament" comes from the fact that the two ligaments are located cross in the center of our knee.
A strain or a tear in the cruciate ligament occurs when the force on our knees is so strong that it can no longer be alleviated by the muscles, especially for sudden turns, stops or starts. These movements mostly take place in sports such as football or tennis.
Knee pain when stretching
Knee pain is often associated with certain movements - for example when stretching or stretching of the leg or knee. This is a typical movement in Climb stairs. The pain associated with such specific movements can also indicate damage to the knee. An investigation is recommended, if Pain when climbing stairs should occur every day.
In principle, the pain when stretching can of course have several causes. Three of the most common causes for this are:
- Damage to the miniscus
- Tip patella syndrome
- Patella dislocation
Knee pain when standing up
If you experience pain in your knee after lying or sitting for a long time, this may be an indication of the knee joint. Typically, these start-up pains disappear again after movement and the knee feels normal and resilient again after a few minutes. However, it is common for the pain in the further course of other movements (e.g. climbing stairs) also occurs and accumulates.
Knee pain when getting up can also occur if one Inflammation of the tendon exists between the kneecap and the shinbone (tip patella syndrome).
Overuse syndromes in the knee
An overload syndrome in the knee can occur, for example, when jumping or running a lot in a marathon or basketball. Our kneecap is enclosed by the patellar tendon, which runs vertically over the knee joint at the front. If this tendon is exposed to strong tensile forces over a long period of time, it can become irritated and cause pain below the kneecap at the attachment point. Here we are talking about one Tip patella syndrome. Another common overuse syndrome is the "Chondropathia Patellae"in which the cartilage in the knee slowly becomes softer and can no longer adequately protect the back of the kneecap. Straightening the joint after long periods of squatting or sitting is often associated with pain.
Dislocated knee: patella dislocation
The kneecap can also jump out of its fixed position and cause great pain in the knee joint. This type of injury is commonly known as a dislocation and is particularly painful in the knee. The medical name of this injury is Patella dislocation.
In most cases, however, the kneecap jumps back into the knee joint on its own. Nevertheless, a medical examination is recommended after an incident in order to rule out subsequent injuries to the ligaments or. However, if the kneecap does not jump back into its original position by itself and remains in the dislocated position, medical care is essential. Although this is comparatively rare, it still occurs. A reduction is then still possible, but should definitely be carried out by a doctor, as this type of dislocation increases the risk of severe or permanent knee damage.
In addition to sporting activities, congenital or chronic conditions can also affect the kneecap and make a dislocation more likely. These include B .:
- Patella dysplasia (congenital deformity or malformation of the kneecap)
- Genu Valgum (commonly referred to as knock knees)
- Patella Alta (upright kneecap)
Symptoms of knee osteoarthritis
One is called joint wear in everyday language. After an injury or simply through years of movement of the knee joint, the cartilage slowly rubs off, which can then cause pain when moving. At an advanced stage, the cartilage can be broken down to such an extent that bone rubs on bone.
