If tenosynovitis recurs repeatedly and is not given enough attention, it can become quite persistent and may not significantly improve with appropriate treatment. In such cases, surgery may be necessary. When tenosynovitis worsens, it leads to local pain, limited movement, and even noticeable swelling. Generally, there is no malignant transformation in the local tissues of tenosynovitis. The underlying mechanism of tenosynovitis involves aseptic inflammation due to the tendons' load-bearing activities. Long-term recurrence can lead to local scar hyperplasia. Post-surgical treatment should avoid repeated load-bearing activities to reduce recurrence.
