Knee pain is pain in or around the knee.
The knee joint consists of the articulation between the four bones: the femur, the tibia, the fibula and the patella. There are four compartments in the knee. This is the medial and lateral tibiofemoral compartment, the patellofemoral compartment and the superior tibiofibular joint. The components of each of these compartments may experience strain, injury or recurrent disease.
Running in long distances can cause pain in the knee joint, because the exercise is high-impact.

Cause
Injuries
Some common injuries include:
- Sprain (Sprain Ligament)
- medial collateral ligament
- Lateral collateral ligament
- Anterior cruciate ligament
- Posterior cruciate ligament
- Rat meniscus
- Medial median
- lateral type
- Filter (Strain)
- Quadriceps muscle
- Hamstring muscle
- Popliteal muscle
- patellar tendon
- Hamstring tendon
- Poplite tendon
- Hemarthrosis - Hemarthrosis tends to develop in a relatively short time after injury, from a few minutes to several hours.
Fracture
- Fracture femoral
- Tibial Fracture
- Patella fracture
Disease
Some diseases that cause knee pain include the following:
- Osteoarthritis of the knee
- Chondromalacia patella
- Baker Kista
- Meniscal cyst
- Discoid meniscus
- Osgood-Schlatter's disease
- Larsen-Johansson disease
- Knee rheumatoid arthritis
- Osteochondritis dissecans disease
- Synovial chondromatosis disease
- Tumor
- Ankylosing spondylitis
- Reactive arthritis
- Tuberculosis arthritis
- Septic arthritis ( piogenic arthritis )
- Osteomyelitis
- Hemophilic arthritis
- Gout (Gouty arthritis)
- Neuroma
Inflammation
- Bursitis on the knee
- Prepatellar bursitis - The knee of the maid (most common)
- Infrapatellar bursitis - Clergyman's knee ( Superficial inflexible bursitis and Infrapatellar bursitis in )
- Semimembranosus bursitis
- Tendinitis
- Patella tendinitis ( Jumper knee )
- Hamstring tendinitis
- Poplite tendinitis
- Knee synovitis
Disorder
Common knee deformities include:
- Bipartite patella (two parts kneecap)
- Genu varum (leg bow)
- Genu valgum (knock-knees)
- Genu recurvatum (Knee hyperextension)
- Knee deformity knee
Syndrome
- Patellofemoral pain syndrome
- Plica syndrome
- Iliotibial Band Syndrome
- Hoffa Syndrome
Dislocation
- Patella dislocation
- Dislocation of the knee joint ( Tibiofemoral joint dislocation )
Cold-induced
A study in China concluded that knee pain is significantly more prevalent in people who work in cold stores than those who are in normal temperature.
One study came to the conclusion that 17% of adolescents with anterior knee pain (general restricted condition) reported that their pain was associated with cold weather. The same study shows that the main activities associated with anterior knee pain are exercise, climbing stairs and walking, but also sitting. Some people with anterior knee pain tend to have colder knees, and such people also tend to wear extra trousers/long trousers in the winter.
Knee-induced knee pain may also be caused by tenosynovitis of the tendon around the knee, where cold exposure has a special role, either as a cause or contributing factor. Frank's arthritis has been reported in children due to frostbite from extreme cold that causes direct chondrocytic injury.
There is also hereditary disease, cold familial autoinflammatory syndrome (FCAS), which often presents knee pain, other than itching, fever and pain in other joints, after a general exposure to cold.
Cold weather also worsens knee pain in patients who already have osteoarthritis, rheumatoid arthritis and fibromyalgia.
Knee pain due to less physical movement
Lower levels of physical activity and the work environment in which a person is asked to sit on a chair during the workday is one of the reasons for developing knee joint pain, since lower levels of physical movement tend to weaken the knee muscles. The blood vessels may also be affected, leading to the development of a painful condition.
As the ages of knee joint motion involves higher friction with adjacent tissues and cartilages.
Other causes
- Weakness of ligaments
- Throwing a fat pad
- Knee effusion
- deep vein thrombosis
- Peripheral vascular disease
- Exostosis
Recommended knee pain
The pain in question is the pain that is felt at a site different from its original point but is innervated by the same spine segment. Sometimes knee pain may be related to other areas of the body. For example, knee pain can come from ankles, legs, hip joints or lumbar spine.

Diagnosis
MRI knee should be avoided for asymptomatic knee pain or effusion, unless there is an unsuccessful outcome of the functional rehabilitation program.
Management
Although surgery has a role in improving traumatic injuries and fractures, surgery such as arthroscopic lavage does not provide significant or lasting improvement to pain or function in people with degenerative knee pain, and is therefore almost never done. Degenerative knee pain is pain caused by wear and tear, such as osteoarthritis or meniscus tears. Effective treatments for degenerative knee pain include physical therapy exercises, painkillers such as ibuprofen, knee replacement surgery, and weight loss in overweight people.
Epidemiology
Approximately 25% of people over the age of 50 years experience knee pain due to degenerative knee disease.
Society
In the United States, more than US $ 3 billion is spent annually for arthroscopic knee surgery that is known to be ineffective in people with degenerative knee pain.
