Spontaneous fractures occur mainly in athletes, dancers and the military providing intense and repetitive efforts, or overtrained (long marches, multiple jumps, etc.).
The hygroma of the knee (or pre-patellar bursitis) is an inflammation of the so-called pre-patellar bursa, located at the front of the knee. It becomes painful and swollen. This condition is often seen in people who work on their knees (eg tilers).
Bursitis may also occur at the level of the popliteal stock exchange, located at the back of the knee, causing the appearance of a cyst at this location (cyst of the popliteal fossa).
ALS is a set of symptoms that sometimes occurs after surgery or trauma: pain, joint stiffness, circulatory disorders with red and thinned skin, bone decalcification (significant decrease in calcium content), etc.
Aseptic osteonecrosis of the femoral condyles is bone destruction in the femoral condyles, of non-infectious origin. It occurs in the elderly.
Hip pain can also affect the knee (for example, in case of osteoarthritis of the hip).
Osgood-Schlatter’s disease is also called “anterior tibial epiphysitis”. It is an inflammation and fragmentation of the anterior tibial tuberosity (small bony hump located at the front of the tibia). Probably due to an excess of sport, this affection appears especially in the boy between 10 and 15 years.
Paget’s disease causes deformity and anarchic reorganization of the bones. Of unknown origin, it occurs most often after 50 years.
Non-Traumatic Knee Pain (Gonalgia) Of Inflammatory Origin
Various pathologies are likely to cause this type of gonalgia.
Systemic inflammatory diseases sometimes cause knee pain: rheumatoid arthritis, systemic lupus erythematosus, rheumatism associated with psoriasis, ankylosing spondylitis, polyarthritis of the child (chronic inflammation of the joints in children under 16).
The so-called “microcrystalline” rheumatism (linked to the accumulation of tiny crystals in the joints) also causes gonalgia.
Gout is characterized by the formation of uric acid crystals in the joint fluid. This phenomenon is related to an increase in the blood level of uric acid, which is no longer normally eliminated in the urine because of certain conditions.
Chondrocalcinosis is calcium crystal deposits on articular cartilage and menisci.
Painful tendinitis of the knee can affect:
the crow’s feet (tendon fixing three muscles of the thigh to the internal face of the knee),
the patellar tendon, which goes from the lower part of the patella to the shin,
the quadricipital tendon (connecting the quadriceps muscle of the thigh to the upper part of the patella).
An infectious arthritis (due to a bacterium present in the joint), or an osteo-arthritis (infection of the joint and the neighboring bone), sometimes explain the gonalgies.
Rarely, these are due to a tumor or cancer, which can affect the various components of the joint (bone, cartilage, etc.).
