Five reasons your knee hurts when straight but not when bent

The knee joint is the strongest joint in the human musculoskeletal system. It takes the brunt of the load and helps maintain balance. When something goes wrong with the knee, it impairs the locomotive function of the entire musculoskeletal system. Moreover, nagging and dragging pains in the knee can cause a lot of discomfort and disrupt a person’s ability to function normally. Why do patients very often consult traumatologists and orthopaedists when they encounter knee pain, which occurs predominantly when bending or extending the joint? What is the cause of this trend and what is the underlying cause of pain in the knee? Often, knee pain can only be a symptom of an underlying medical condition. If this is the case, you should seek advice and a diagnosis from your knee doctor as soon as possible. 

Causes of knee pain

The largest joint in the human body is thought to be the knee. It is protected by cartilage pads called menisci. If a person experiences pain in the knee joint during movement, it may be due to the following reasons:

  1. inflammation of the periarticular sac;
  2. muscle tone disorders;
  3. injury to the knee cartilage;
  4. tendon injuries;
  5. salt accumulation.

All of the conditions listed above require immediate treatment because if they are ignored, they can lead to serious consequences that are difficult to treat. If you do not want to make things worse, we recommend that you see a doctor and that you buy knee braces to support the joints and stop the degenerative and dystrophic processes in the knee.

Knee extension pain is often associated with a condition such as arthritis. Most of the time it affects middle-aged and elderly people. When this disease affects a person, they not only feel pain but also stiffness in the joint. These symptoms are accompanied by severe swelling, redness, and an increase in local temperature. Sometimes the pain is caused by injuries. This problem most often occurs after:

  • Severe knocks to the knee;
  • Prolonged unnatural positioning of the joint;
  • A fall on the knee.

The pain is caused by bruises, fractures, contusions and dislocations. Swelling, numbness and tingling also occur after an injury to the affected area.

How do I treat knee pain?

The first rule to stick to when treating painful knees is to limit or even stop physical activity for a while. Once the pain has subsided or become minimal, you can return to sports, but only after an individual consultation with a specialist. You should also reconsider the shoes you wear. Avoid shoes with high heels or platforms. It is best to buy orthopaedic shoes and be sure to use orthopaedic insoles, which will help support the knees and minimise the chance of pain progression. It is advisable to apply a cold compress to the knee at the time of pain.

In the case of a bacterial aetiology of the disease, you should have your doctor prescribe an antibiotic therapy as well as pain-relieving and anti-inflammatory medication. It is also important to use topical ointments and don’t forget to rest.
