Response of synovial membrane to trauma from a direct blow or forced movement inflammatory reaction of synovial membrane.
Onset of symptoms is usually 12-24 hours after trauma commonly get a ‘tight’ sensation from effusion. Not often associated with large amounts of warmth, erythema or tenderness.
A reactive synovitis may result in symptoms being present for several months – even following minor trauma.
Initial – ice, compression, NSAID’s, aspiration if effusion large, range of motion exercises when tolerated
After first week – heat, exercises, electrotherapeutic modalities, repeated aspirations if effusions continue.
