Whether it is better to treat tenosynovitis with a needle knife or a seal depends on the patient’s specific situation and it is impossible to compare which method is better. If the tendinitis is of long duration or if adhesions are present, it is recommended to choose the needle knife. This approach loosens the adhesions and has a lower recurrence rate. For shorter duration of the disease, where adhesions have not formed, closure therapy can be used. Closure injections for tenosynovitis can reduce swelling, inflammation, and pain relief, thus restoring joint function. This method has a fast recovery time, but the number of closed treatments should not be too many. Cure tendinitis choose needle knife or closed, it is recommended to listen to the professional doctor’s opinion, do not blindly decide on your own to avoid unnecessary effects.
