Synovitis surgery can be completely cured after 3 weeks. This is the time for incision healing and synovial repair, so no strenuous exercise should be performed during this period, and the affected limb should be elevated to reduce weight bearing, which can promote local tissue recovery. Synovitis surgery can also produce a certain amount of effusion, which requires active physical therapy and oral medication, such as glucosamine sulfate capsules, aminochondroitin sulfate and fotarine tablets, all of which can play a good role in the later treatment. Restriction of activity is the main thing, because restricting activity after repair can promote local recovery. If strenuous exercise is performed, it will lead to aggravation of the injury, resulting in increased joint effusion, as well as increased joint swelling and pain symptoms.
