Synovectomy refers to the surgical removal of the synovial membrane, which is the thin layer that lines the joints. This procedure is typically performed in cases where a patient experiences inflammation and swelling of the synovial membrane due to a chronic condition like arthritis. Some synonyms for synovectomy include joint cleaning, arthrectomy, joint debridement, joint lavage, joint scraping, or synovial debridement. However, it's important to note that these terms are not always interchangeable and may refer to slightly different procedures. Patients should always consult with their healthcare provider to confirm which procedure is appropriate for their condition.
