What happens if I have radiotherapy for villonodular synovitis

The long and difficult-to-pronounce term "radiotherapy for villonodular synovitis" not only makes people dizzy, but also makes people confused and at a loss. Many people are confused and don't know what radiotherapy for villonodular synovitis is. Some people know about radiotherapy for villonodular synovitis but don't know what the results will be. Let me introduce it to you today.

Pigmented villonodular synovitis is relatively rare and comes in two types: villous and nodular. Most of the patients are young and middle-aged men. Most of them are between 20 and 40 years old. This disease often occurs in the knee and ankle joints. The treatment of this disease includes surgical resection and radiotherapy. Surgical resection is more thorough and is particularly suitable for nodular cases. Radiation therapy is more effective for the villous type but less effective for the nodular type. For diffuse lesions, all synovial tissue should be removed to avoid recurrence. For villous lesions of the knee joint with abundant synovium that are difficult to completely remove, the synovial tissue in front and behind the joint can be removed as much as possible first, and radiotherapy can be performed after surgery to achieve the goal of cure.

For diffuse nodular lesions of the knee joint, the cruciate ligament and collateral ligament should be cut, the joint should be dislocated, and the anterior and posterior synovial tissue should be completely removed. If the nodular lesions are not completely removed, they are very likely to recur, and in a small number of cases, they may turn into synovial sarcoma. For localized lesions, only the local synovial tissue needs to be removed. However, the disease is prone to relapse, and a few may become malignant. Recurrent cases should be closely tracked and studied.

Pigmented villonodular synovitis is a proliferative disease of unknown etiology that occurs most frequently in synovial joints, tendon sheaths, and bursae. Generally it can be divided into two types. Those located in the synovium of the joint are mostly diffuse, while those located in the tendon sheath and bursa are mostly localized. The disease is more common in young and middle-aged people, more than 80% occur in 20-40 years old, more males than females, the disease develops slowly, the disease period is mostly 1-4 years, and can be as long as ten years. The knee joint is most commonly affected, but the hip joint can also be affected.

The most common knee symptoms are swelling of the joint and progressive pain, discomfort, and stiffness. Patients may or may not have a history of trauma. When the lesion involves the cartilage and bone, symptoms such as pain when going up and down stairs, pain when half-squatting, joint clicking when flexing and extending, and locking may occur. Examination may reveal joint swelling, especially in the suprapatellar bursa. Sometimes synovial masses or nodules can be felt, and the range of joint motion may be reduced. The most important thing is to do a joint aspirate examination and a pathological examination of the synovial tissue.

The treatment of localized type is mainly local resection, but the resection must be thorough and clean, and radiotherapy can be used as an auxiliary after surgery if necessary. For diffuse type, total synovectomy is generally performed, followed by postoperative radiotherapy and enhanced functional exercise. The chemotherapy you mentioned is of little significance and is rarely used clinically. Generally, surgery combined with radiotherapy is the most ideal.

The above content is the relevant knowledge about radiotherapy of villonodular synovitis introduced to you today. I believe you will understand it after reading it. Radiotherapy has always been a word and treatment that people fear, but if it is necessary, please be strong and face it. After all, healing your body comes first. At the same time, exercise more often every day to enhance immunity.
