How is a Baker's cyst in the right knee treated?

Generally, a popliteal cyst in the right knee may be caused by physiological structural defects, abnormally increased intra-articular pressure, medial meniscus injury, synovitis, joint degenerative changes, and other factors. General treatment and medication can be used to improve the condition. Prompt medical attention is required, and treatment should follow medical advice. Details are as follows:

1. Physiological structural defect: The popliteal region is located between the medial head of the quadriceps femoris muscle, the joint cavity, and the semimembranosus bursa. This structure can only receive and store synovial fluid but cannot return the synovial fluid flowing into the cyst back to the joint cavity, resulting in continuous enlargement of the cyst and progression of the condition. If symptoms are mild, elastic bandage compression can be used to alleviate discomfort. If the cyst is large or symptoms are severe, surgical treatment should be considered, such as arthroscopic cyst excision.

2. Abnormally increased intra-articular pressure: Unhealthy lifestyle habits, such as prolonged standing or strenuous activity, may lead to increased intra-articular pressure, causing synovial fluid to flow into the fissures and form a cyst. Patients should change unhealthy lifestyle habits, such as reducing the duration of standing and strenuous activity.

3. Medial meniscus injury: Injury to the medial meniscus may lead to increased intra-articular pressure, causing synovial fluid to flow into the popliteal fissures and form a cyst, resulting in knee pain. Under the guidance of a physician, surgical treatments such as meniscus suturing, meniscectomy, or meniscus replacement can be considered.

4. Synovitis: Synovitis may cause synovial hyperplasia and intensified inflammatory reactions within the joint cavity, leading to excessive fluid accumulation and the formation of a popliteal cyst, resulting in knee swelling. Anti-inflammatory medications such as ibuprofen sustained-release capsules, celecoxib capsules, and acetaminophen tablets can be used according to medical advice.

5. Joint degenerative changes: Degenerative joint disease is caused by pathological changes such as uneven joint surfaces and narrowed joint spaces due to aging and long-term overuse, increasing friction during joint movement and inducing the formation of popliteal cysts, leading to joint stiffness. Pain-relieving and anti-inflammatory medications such as celecoxib capsules, loxoprofen sodium tablets, and amoxicillin capsules should be used under the guidance of a physician.

During treatment, attention should be paid to adjusting lifestyle habits and dietary habits to promote recovery.
