Common Causes of Knee Pain

Common Causes of Knee Pain

Knee pain can be frustrating and life-altering. It is, however, important to quickly address knee pain. The knee is a complex joint between the bones of the upper and lower leg. It allows the leg to bend and provides stability to support the weight of the body. The knee supports motions such as walking, running, jumping, hopping, squatting, and turning. The knee joint is made up of bones, cartilage, muscles, ligaments, and tendons. Any of these parts can lead to injury and cause knee pain. If you face any knee issues or joint pain, it could be advisable to see a doctor. They can provide you with appropriate medications for pain as well as for better joint health.

Note: If you are prescribed pain meds like oxycodone or hydrocodone, you can also research their prices, for instance, with keywords like the street value of Hydrocodone to ensure you get the best price in the market.

Common symptoms of knee pain:

      • Swelling and stiffness
      • Redness and warmth to the touch
      • Weakness or instability
      • Popping or grinding noises
      • Inability to fully straighten the knee

Common causes of knee pain:

    • Injuries:
        • ACL injury. An ACL injury is a tear of the anterior cruciate ligament (ACL). An ACL injury is particularly common in people who play basketball, soccer or other sports that require sudden changes in direction.
        • Fractures. The bones of the knee, including the kneecap (patella), can be broken during motor vehicle collisions or falls.
        • Torn meniscus. The meniscus is formed of tough, rubbery cartilage and acts as a shock absorber between your shinbone and thighbone. It can be torn if you suddenly twist your knee while bearing weight on it.
        • Knee bursitis. Some knee injuries cause inflammation in the bursae, the small sacs of fluid that cushion the outside of your knee joint so that tendons and ligaments glide smoothly over the joint.
        • Patellar tendonitis. Tendonitis is irritation and inflammation of one or more tendons (the thick, fibrous tissues that attach muscles to bones). Runners, skiers, cyclists, and those involved in jumping sports and activities may develop inflammation in the patellar tendon, which connects the quadriceps muscle on the front of the thigh to the shinbone.
    • Mechanical problems:
        • Patellofemoral pain syndrome. The patellofemoral joint is the area of the Patella (knee cap) where the Patella sits in a groove in the Femur (tight bone).The Patella (knee cap) has an underlying surface covered with articular cartilage that allows it to glide smoothly in the knee. The Patella shifts within this groove during active movement of the knee.When this mechanism (tracking of the Patella in femoral groove) does not work properly, the cartilage becomes irritated/worn leading to maltracking or excessive shifting of Patella, resulting in pain. This process is referred to as dysfunctional patellar tracking, patellar maltracking, or patellofemoral pain syndrome.
        • Loose body. Sometimes injury or degeneration of bone or cartilage can cause a piece of bone or cartilage to break off and float in the joint space. This may not create any problems unless the loose body interferes with knee joint movement, in which case the effect is something like a pencil caught in a door hinge.
        • Iliotibial band syndrome. This occurs when the tough band of tissue that extends from the outside of your hip to the outside of your knee (iliotibial band) becomes so tight that it rubs against the outer portion of your 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 of your knee slips out of place, usually to the outside of your knee. In some cases, the kneecap may stay displaced and you’ll be able to see the dislocation.
        • Hip or foot pain. If you have hip or foot pain, you may change the way you walk to spare these painful joints. But this altered gait can place more stress on your knee joint. In some cases, problems in the hip or foot can cause knee pain.
    • Arthritis types:
      • Oesteoarthritis. Sometimes called degenerative arthritis, osteoarthritis is the most common type of knee arthritis. It’s a wear-and-tear condition that occurs when the cartilage in your 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 your knees. Although rheumatoid arthritis is a chronic disease, it tends to vary in severity and may even come and go. The remedies and cures may involve prescribed medication or solutions such as medical marijuanas for rheumatoid arthritis provided by a marijuana doctor.
      • Gout. This type of arthritis occurs when uric acid crystals build up in the joint. While gout most commonly affects the big toe, it can also occur in the knee.
      • Pseudogout. Often mistaken for gout, pseudogout is caused by calcium-containing crystals that develop in the joint fluid. Knees are the most common joint affected by pseudogout.

Your knees are vital joints and knee pain should not be ignored as further damage could result. In some cases, especially as you get older, if the knee pain persists or is because of some underlying issue, you may have to consider Knee Replacement surgery. This is nothing to be worried about, however, it can be prevented by adopting the right safety measures early on. Elite Physical Therapy and Balance can quickly evaluate and either begin treatment or refer you on the appropriate path to help you Feel Better Faster.
