Knee pain - Overview

Knee pain is a common complaint that affects people of all ages. Knee pain can be the result of an injury, such as a torn ligament or a torn cartilage. Medical conditions, which include arthritis, gout and infections, can also cause knee pain.

Many types of mild knee pain respond well to self-care measures. Physical therapy and knee pads can also help relieve knee pain. In some cases, however, your knee may require surgical repair.

Knee pain - symptom

The location and severity of knee pain may vary, depending on the cause of the problem. Signs and symptoms that sometimes accompany knee pain include:

  • Swelling and stiffness
  • Redness and heat to the touch.
  • Weakness or instability.
  • Bursting noises or cracks
  • Inability to fully stretch the knee

Knee pain - When to see a doctor

Call your doctor if you:

  • You cannot bear weight on your knee or feel that your knee is unstable (gives up)
  • They have marked knee swelling
  • Cannot fully extend or flex the knee
  • See an obvious deformity in your leg or knee
  • You have a fever, in addition to redness, pain and swelling in the knee.
  • You have severe knee pain associated with an injury.

Knee pain - Causes

Knee pain can be caused by injuries, mechanical problems, types of arthritis and other problems.

Knee pain - Mechanical problems

Some examples of mechanical problems that can cause knee pain include:

  • Loose body Sometimes, lesions or degeneration of bone or cartilage can cause a piece of bone or cartilage to break and float in the joint space. This may not create any problem unless the loose body interferes with the movement of the knee joint, in which case the effect is something like a pencil stuck in a door hinge.
  • Iliotibial band syndrome. This occurs when the band of resistant tissue that extends from the outside of the hip to the outside of the knee (iliotibial band) becomes so tight that it touches the outside of the femur. Distance runners and cyclists are especially susceptible to iliotibial band syndrome.
  • Dislocated kneecap. This occurs when the triangular bone (patella) that covers the front part of the knee slides out of place, usually towards the outside of the knee. In some cases, the patella may remain displaced and you can see the dislocation.
  • Hip or foot pain. If you have pain in your hip or foot, you can change the way you walk to avoid these painful joints. But this altered gait can generate more stress in the knee joint. In some cases, problems in the hip or foot can cause pain in the knee.

Knee pain - Injuries

A knee pain  injury can affect any of the ligaments, tendons, or fluid-filled sacs (bags) that surround the knee joint, as well as the bones, cartilage, and ligaments that make up the joint itself. Some of the most common knee injuries include:
  • ACL injury. An ACL injury is a rupture of the anterior cruciate ligament (ACL), one of the four ligaments that connect the shin to the femur. An ACL injury is particularly common in people who play basketball, football or other sports that require abrupt changes of direction.
  • Fractures Knee bones, including the kneecap (kneecap), can break during collisions or falls from motor vehicles. People whose bones have been weakened by osteoporosis can sometimes suffer a broken knee simply by taking a false step.
  • Meniscus broken. The meniscus is made of hard and gummy cartilage and acts as a buffer between the shin and the femur. It can break if you suddenly turn your knee while supporting weight on it.
  • Knee bursitis Some knee injuries cause inflammation in the bags, the small sacs of fluid that cushion the outside of the knee joint so that the tendons and ligaments slide smoothly over the joint.
  • Patellar tendonitis Tendonitis is irritation and inflammation of one or more tendons, the thick and fibrous tissues that attach the muscles to the bones. Runners, skiers, cyclists and those involved in sports and jumping activities can develop inflammation in the patellar tendon, which connects the quadriceps muscle in the front of the thigh with the shin.

Knee pain - Types of arthritis

There are more than 100 types of arthritis. The varieties most likely to affect the knee include:

  • Osteoarthritis. Sometimes called degenerative arthritis, osteoarthritis is the most common type of arthritis. It is a condition of wear that occurs when the cartilage of the knee deteriorates with use and age.
  • Rheumatoid arthritis. The most debilitating form of arthritis, rheumatoid arthritis is an autoimmune condition that can affect almost any joint in your body, including the knees. Although rheumatoid arthritis is a chronic disease, it tends to vary in severity and may even come and go.
  • Gout. This type of arthritis occurs when uric acid crystals accumulate in the joint. While gout most commonly affects the big toe, it can also occur in the knee.
  • Pseudo drop. Often confused with gout, pseudogout is caused by calcium-containing crystals that develop in joint fluid. The knees are the most common joints affected by pseudogout.
  • Septic arthritis. Sometimes, the knee joint can become infected and cause swelling, pain and redness. Septic arthritis often occurs with fever, and there is usually no trauma before the onset of pain. Septic arthritis can quickly cause extensive damage to the cartilage of the knee. If you have knee pain with any of these symptoms, consult your doctor immediately.

Knee pain - Other problems

Patellofemoral pain syndrome is a general term that refers to the pain that arises between the patella (patella) and the underlying femur (femur). It is common in athletes; in young adults, especially those who have a slight poor follow-up of the patella; and in older adults, who generally develop the condition as a result of arthritis of the patella.

Knee pain - Complications

Not all knee pain is severe. But some knee injuries and medical conditions, such as osteoarthritis, can cause increased pain, joint damage and disability if left untreated. And having a knee injury, even a mild one, makes it more likely to have similar injuries in the future.

Knee pain - Prevention

Although it is not always possible to prevent knee pain, the following suggestions can help prevent injuries and joint damage:

  • Keep extra pounds off. Maintain a healthy weight; it's one of the best things you can do for your knees. Every extra pound puts additional strain on your joints, increasing the risk of injuries and osteoarthritis.
  • Be in shape to play your sport. To prepare your muscles for the demands of sports participation, take time for conditioning. Work with a coach or trainer to ensure that your technique and movement are the best they can be.
  • Practice perfectly. Make sure the technique and movement patterns you use in your sports or activity are the best they can be. Lessons from a professional can be very helpful.
  • Get strong, stay flexible. Because weak muscles are a leading cause of knee injuries, you'll benefit from building up your quadriceps and hamstrings, which support your knees. Balance and stability training helps the muscles around your knees work together more effectively. And because tight muscles also can contribute to injury, stretching is important. Try to include flexibility exercises in your workouts.
  • Be smart about exercise. If you have osteoarthritis, chronic knee pain or recurring injuries, you may need to change the Mantenga kilos de más. Mantener un peso saludable; Es una de las mejores cosas que puedes hacer por tus rodillas. Cada libra adicional ejerce una presión adicional sobre sus articulaciones, lo que aumenta el riesgo de lesiones y osteoartritis.
  • Estar en forma para practicar tu deporte. Para preparar sus músculos para las exigencias de la participación deportiva, tómese un tiempo para el acondicionamiento. Trabaje con un entrenador o entrenador para asegurarse de que su técnica y movimiento sean lo mejor posible.
  • Practica perfectamente. Asegúrese de que la técnica y los patrones de movimiento que utiliza en sus deportes o actividades sean lo mejor posible. Las lecciones de un profesional pueden ser muy útiles.
  • Hazte fuerte, mantente flexible. Debido a que los músculos débiles son la principal causa de lesiones en la rodilla, se beneficiará al desarrollar sus cuádriceps e isquiotibiales, que sostienen sus rodillas. El entrenamiento de equilibrio y estabilidad ayuda a que los músculos alrededor de las rodillas trabajen juntos de manera más efectiva. Y debido a que los músculos tensos también pueden contribuir a las lesiones, el estiramiento es importante. Intenta incluir ejercicios de flexibilidad en tus entrenamientos.
  • Sé inteligente sobre el ejercicio. Si tiene osteoartritis, dolor crónico de rodilla o lesiones recurrentes, es posible que deba cambiar la forma en que hace ejercicio. Considere cambiar a natación, aeróbicos acuáticos u otras actividades de bajo impacto, al menos durante unos días a la semana. A veces, limitar las actividades de alto impacto proporcionará alivio. or other low-impact activities — at least for a few days a week. Sometimes simply limiting high-impact activities will provide relief.

Knee pain - Risk factor's

Several factors can increase your risk of having knee problems, including:

  • Overweight. Being overweight or obese increases stress on the knee joints, even during normal activities such as walking or going up and down stairs. It also increases the risk of osteoarthritis by accelerating the breakdown of joint cartilage.
  • Lack of flexibility or muscular strength. Lack of strength and flexibility can increase the risk of knee injuries. Strong muscles help stabilize and protect your joints, and muscle flexibility can help you achieve a full range of motion.
  • Certain sports or occupations. Some sports put more pressure on the knees than others. Alpine skiing with its rigid ski boots and the possibility of falls, jumps and pivots of basketball, and repeated blows of the knees when you run or jog increase the risk of knee injury. Jobs that require repetitive stress on the knees, such as construction or agriculture, can also increase your risk.
  • Previous Injury Having a previous knee injury makes it more likely to injure your knee again.
