Patient Q & A Section
What are the signs of arthrofibrosis?
Joint hypermobility, effusion, and soft tissue swelling are common findings in arthrofibrosis. Joint laxity can be assessed by a thorough history, physical examination, and arthrography. Should a thorough history and physical not reveal a specific radiographic pattern, an arthrography can be performed to identify fibrosis within the capsule. In patients with an effusion in clinical exam or arthrography, an aspiration can be done for confirmation. Soft tissue swelling can be confirmed in arthrofibrosis with magnetic resonance imaging and biopsy.
Can arthrofibrosis be cured?
Arthrofibrosis (Arthrofibrous synoviitis/osteoarthritis) has been cured or improved in a significant proportion of patients treated with conventional and surgical treatment modalities, but in most cases, recurrence is usually inevitable. Arthroscopy (with or without debridement) can help control pain but has a poor efficacy in halting disease progression or delaying further surgery.
How many people get arthrofibrosis a year in the United States?
Approximately 5,500 cases of arthrofibrosis will be diagnosed in the United States in 2022. Of this number, around 30,000 will develop a degenerative joint disease. These statistics imply patients with rheumatoid arthritis and osteoarthritis will be the most affected groups in terms of joint damage.
What is arthrofibrosis?
Arthrofibrosis is an abnormal scar formation of bony, cartilaginous, or ligamentous structures. In many cases, the fibrocartilage changes into a fibrinous/fibrous mass and the surrounding bone becomes exposed. The bony portion is most commonly the hip and shoulder joints, but can occur in other joints throughout the body. While arthrofibrosis can affect the entire body, the most common site involved is the hip. Because of joint dysfunction, and pain in the affected areas of the body, some people affected by arthrofibrosis can have a negative impact on their quality of living. The diagnosis of arthrofibrosis will take a full history and physical exam.
What causes arthrofibrosis?
Arthrofibrosis can result from a myriad of conditions that can lead to excessive load on cartilage. Excessive load can occur for medical reasons, such as joint injuries, or for pleasure, such as from dance, gymnastics, or weight lifting. Other causes of excessive load include osteoporosis, endocrine disorders, and genetic susceptibility. Excessively strong forces are required before arthrofibrosis may occur. Arthrofibrosis develops following the initial injury of the joint. There must also be a period of time of excess stress with the loading in order for the joint tissue to get to a point where it can become a site of inflammation and further injury.
What are common treatments for arthrofibrosis?
Surgery, steroid injection, and a variety of nonoperative treatments are effective for the relief of symptoms. Surgical treatments, such as arthrodesis and arthroplasty, provide durable relief from arthritis deformity and stiffness in most patients with arthrofibrosis.
Does losartan improve quality of life for those with arthrofibrosis?
Treatment for ARTF, a condition resulting in reduced quality of life, improves a participant's quality of life. Our analyses suggest that treatment not only alleviates symptoms, but also improves quality of life.
How serious can arthrofibrosis be?
When used properly, arthroscopy can be a very safe procedure, with no complications, and very low revision rates. It is not rare to need arthroscopic lavage if there is a substantial articular lesion and/or active synovitis with gross joint mobility.
What is the latest research for arthrofibrosis?
There is new research in this field, but some of it is being presented at the same same time as other research. Power is helping you look for trials that are interesting to join.
What is the primary cause of arthrofibrosis?
The presence of arthrofibrosis has a greater prevalence among those with osteoarthritis. However, arthrofibrosis is also common in the absence of osteoarthritis. The degree of arthrofibrosis may be the underlying mechanism leading to arthritic changes in the knee.
Is losartan safe for people?
Given the low doses utilized in the current study, the lack of significant side effects, and the excellent efficacy, losartan appears to be a safe agent for people with high CVD risk.
What does losartan usually treat?
We did not find any clinical trials on arthrofibrosis in the journal, 'Arthritis in Clinical Practice (AICP)'. However, based on the findings, there are two known factors that may decrease ARF: a) lower blood pressure; and b) proper bone health. Therefore, if you are a person experiencing arthrofibrosis, you can take blood pressure and bone medicine to maintain your health.
