The knee with osteoarthritis is shown in this comparative illustration between a healthy joint and a degenerated one. In the image, a normal knee with intact cartilage and preserved joint space is visible. Moreover, smooth movement is illustrated. Furthermore, the other side shows cartilage wear. On the other hand, affected areas are clearly identified.
In this case, the knee with osteoarthritis is a degenerative disease characterized by progressive cartilage loss. Additionally, this deterioration reduces cushioning capacity. Consequently, bones come into direct contact. Likewise, this causes pain and inflammation. For example, mobility in daily activities is affected.
From a pathophysiological perspective, cartilage progressively wears down. Moreover, joint biomechanics are altered. Furthermore, osteophytes may develop. On the other hand, the synovial membrane may become inflamed. Consequently, structural and functional damage worsens.
Regarding symptoms, the knee with osteoarthritis presents with joint pain. However, stiffness may also occur. Additionally, swelling is common. For example, difficulty walking may appear. Likewise, symptoms worsen with activity.
On the other hand, risk factors include aging. Consequently, excess weight increases joint stress. Moreover, previous injuries may contribute. Furthermore, genetic factors may play a role. Overall, these elements increase disease risk.
Diagnosis is based on clinical evaluation. Moreover, X-rays show cartilage wear. Furthermore, imaging studies provide additional detail. Consequently, severity is determined. On the other hand, treatment is guided.
Finally, treatment of the knee with osteoarthritis includes conservative measures. For instance, exercise and physical therapy are recommended. However, medications such as analgesics are also used. Additionally, advanced cases may require joint replacement surgery. In conclusion, proper management improves quality of life.
