The treatment of knee tenosynovitis varies according to the severity of tenosynovitis. If the tendovaginitis is mild, it can be treated with local plasters, such as pain-relieving and bone-penetrating plasters, dog skin plasters, etc., and local physiotherapy or hot compresses can also be carried out. If tendovaginitis is more serious, you can take oral medication, such as non-steroidal anti-inflammatory drugs diclofenac sodium or ibuprofen, and proprietary Chinese medicines such as Shuangteng Tendon Tablets, which are more effective. For more serious tenosynovitis, you can also carry out local closed treatment, the effect is more accurate, usually need to be closed three times, once a week. For tenosynovitis that does not respond to conservative treatment, small needle treatment is performed. If these are not effective, surgery can also be performed to remove the tenosynovitis completely, the effect is more obvious, will be completely cured.
