The human array works like a simple hinge. But it has a complex anatomy. The knee joint consists of cartilage, meniscus, anterior cruciate ligament, posterior cruciate ligament, lateral ligaments, and joint capsule.Causes of knee pain?
The most common complaints in the knee;
- Knee pain
- Knee Swelling
- Knee Locking
- Knee Stiffness
- Insecurity in the Knee
Knee pain is classified as follows;
- Widespread and continuous
- Sudden and sharp
- At a certain point
- Reflected pain
Common causes of knee pain usually knee joint calcification (Osteoarthritis) or inflammatory diseases such as rheumatoid arthritis and gout. Calcification pain occurs around the knee, increases with movement and activity. Inflammatory pain continues day and night and at rest.
Sharp and sudden pain arises when the meniscus tears. Knee mechanical problems cause sudden pain in the knee.
Flammable or burning pain occurs in inflammation of the tendons. It occurs with excessive strain and increased activity.
The causes of pain according to the placement of the knee are;
- Anterior Knee Pain (Anterior Knee Pain)
- Knee cap calcification (Patellofemoral Arthrosis)
- Knee cap dislocation (Patellofemoral Luxation)
- Patellar tendonitis
- Osgood Schlatter disease
Causes of pain in the knee (Medial)
- Internal meniscus (Medial Meniscus) rupture
- Medial plica syndrome
- Internal side ligament (Medial Collateral Ligament) rupture
- Calcification affecting the inside (Medial Gonarthrosis)
Causes of pain from the outside of the knee
External meniscus tear – lateral meniscus –
Outer lateral ligament rupture – lateral collateral ligament rupture
Posterolateral corner injury-tendinitis-
Calcification affecting the outer part -lateral gonarthrosis
Causes of pain from behind the knee
- Medial or lateral meniscus posterior horn tears
- Popliteal Cyst (Baker cyst)
- Hamstring Tendonitis
There are three main types of knee swelling;
- Sudden swelling after an injury
- Swelling that develops after hours of injury
- Spontaneous swelling: Swelling occurring suddenly in the knee after trauma occurs from intra-articular bleeding or excessive secretion of intra-articular synovial fluid. This condition is called an effusion.
Causes of bleeding into the joint after trauma;
- Anterior cruciate tear (most common)
- Meniscus tear (peripheral meniscocapsular tears)
- Cartilage injury (Osteochondral damage or fracture)
- Cross-link avulsion (rupture) fracture
- If the knee develops slowly in hours or days, this is usually seen after meniscus tears.
Causes of spontaneous or slow developing knee swelling without trauma;
- Rheumatoid arthritis
- reactive synovitis
- Septic Arthritis (Infection)
- Intra-articular hemarthrosis due to bleeding diathesis (bleeding)
The deadlock knee is unable to open a fixed pattern in a certain position. This situation may be due to a situation that makes a mechanical block effect in the directory. The locking may be permanent or can be resolved by itself.
Often the reasons are;
- Rupture of the meniscus
- Loose body (loose body)
The cause of stiffness in the knee joint usually occurs due to arthritis. A hardness that occurs in the early morning depends on rheumatic diseases. However, hard and permanent hardness occurs as a result of calcification.
Insecurity in the Knee
- Conditions that cause distrust, ejaculation or sudden fall in the knee;
- Rupture of the meniscus
- Chronic anterior cruciate ligament rupture
- Intra-articular free body (loose body)
