Hello, the treatment for tendon repair of the fine generally depends on the number of tendons damaged and the finger the tendon is present. But generally the most conservative method of management is to reduce its movement by tying it up with the adjusant finger. Generally non surgical management will take around 2-3 months four you to fully gain the mobility of the finger. But if you are still concerned, we advice you to take an MRI
