Symptoms of chondrosarcoma of the knee

Chondrosarcoma of the knee is a rare malignant bone tumor. The main symptoms include knee pain, swelling and limited mobility. It is necessary to seek medical attention for professional diagnosis and treatment in a timely manner. The appearance of symptoms is closely related to the growth of the tumor, compression of surrounding tissues and pathological changes.

1. Knee pain is one of the typical symptoms of chondrosarcoma. The pain is usually persistent, especially worse at night or during activities. The growth of the tumor will compress the surrounding nerves and blood vessels, causing the pain to increase. Early pain may be mistaken for arthritis or sports injuries, but as the disease progresses, the pain will gradually increase and become difficult to relieve.

2. Knee swelling is also a common symptom. The growth of the tumor will cause local tissue edema and inflammatory response, which will manifest as obvious swelling around the knee. You may feel a lump or mass when you touch it, and the skin surface may become red or swollen or warm. The degree of swelling is related to the size and location of the tumor, and in severe cases it may affect the normal movement of the joint.

3. Limited movement is another important manifestation of chondrosarcoma. Due to the compression and pain of the tumor, the patient may feel stiffness in the knee and difficulty bending or straightening it. Daily activities such as walking, going up and down stairs, etc. will become difficult, and in severe cases, it may even be impossible to stand normally. Limited movement not only affects the quality of life, but may also lead to further decline in muscle atrophy and joint function.

Treatment of chondrosarcoma of the knee requires a personalized plan based on the severity of the disease and the stage of the tumor. Surgical resection is the main treatment method, including wide resection, joint replacement and amputation. Wide resection is suitable for early-stage tumors, and it reduces the risk of recurrence by removing the tumor and surrounding healthy tissue. Joint replacement is suitable for patients whose tumors have invaded the joints, and artificial joints are used to restore joint function. Amputation is the last option and is used for advanced cases where the tumor cannot be completely removed or has spread.

Radiation therapy and chemotherapy are also commonly used as adjuvants. Radiation therapy uses high-energy rays to kill tumor cells and is suitable for cases where surgery cannot completely remove the tumor or the tumor recurs. Chemotherapy uses anticancer drugs to inhibit tumor growth and is often used for advanced or metastatic chondrosarcoma. Common chemotherapy drugs include doxorubicin, cisplatin, and ifosfamide.

Patients need to pay attention to nutritional support and psychological adjustment during treatment. They should eat more foods rich in protein, vitamins and minerals, such as fish, eggs, vegetables and fruits, to enhance immunity. Psychologically, they can relieve anxiety and stress through psychological counseling or joining a patient support group. Regular review and follow-up are the key to ensuring treatment effectiveness and preventing recurrence. The symptoms of knee chondrosarcoma should not be ignored. Timely medical treatment and standardized treatment are important ways to improve prognosis.
