Some of the more severe forms of synovitis can be treated with minimally invasive arthroscopic surgery. The benefit of minimally invasive arthroscopic surgery is that it can quickly remove the inflamed, swollen synovial membrane and achieve rapid relief. It is also less invasive and has considerable benefits for joint recovery, but not all synovitis can be completely healed after arthroscopic treatment. The effectiveness of synovitis treatment depends on the specific cause of the synovitis in addition to the minimally invasive arthroscopic procedure. If the synovitis is caused by damage to the cruciate ligament and meniscus, arthroscopic surgery not only clears the synovial membrane, but also repairs and reconstructs the meniscus and cruciate ligament. In the case of synovitis caused by gout or rheumatoid, in addition to synovial debridement, symptomatic treatment in terms of daily life, diet and medication must be provided to ensure the effectiveness of minimally invasive surgery.
