Clinical information

DJD, also known as osteoarthritis, is a degenerative joint condition that affects the knee, mainly the knee articular cartilage.
DJD of the knee is characterized by knee pain, stiffness, joint effusion, and reduced joint mobility, often worsening with activity and improving with rest.
Over time, DJD leads to one own joint changes in the human body, including the breakdown of cartilage, bone spurs (osteophytes), and inflammation of the synovium.
Aging, joint overuse, genetics, past knee injuries, obesity, and even underlying conditions like rheumatoid arthritis are common risk factors for developing DJD of the knee.
Management and treatment options for DJD of the knee include nonsurgical treatments like medications, physical therapy, lifestyle modifications, injections, and knee replacement surgery, in severe cases.

Synonyms include

Osteoarthrosis of knee
Knee degenerative arthritis
Knee joint wear and tear
