The best treatment for a synovial hernia is surgery; conservative treatment or medication cannot repair the hernia defect. The decision to place a patch to repair the hernia defect is also based on the intraoperative status of the infection. Chronic adhesions at the external orifice due to recurrent hernia bulging can lead to entrapment of the hernia contents. In case of necrosis of the hernia contents, only high ligation of the hernia and removal of the necrotic material can be performed, and no patch can be placed, as this may result in failure of the patch infection, and the patient has a higher chance of recurrence after surgery. If the synovial hernia does not present with ingrown hernia contents and necrosis, high ligation of the hernia sac can be performed at this time. A patch is placed over the hernia defect to achieve a tension-free hernia repair. This is the best clinical treatment for the patient as the probability of recurrence is greatly reduced after surgery.
