Welcome to the forum.Normally knee is surrounded by a membrane called synovium which contains synovial fluid
.Synovial fluid maintains movements at knee joint and provides nourishment to the joint.Neurokind is a tablet
which contains multivitamins used to treat neuropathic type of pain.Rejoint is a nutritional supplement not a
drug.It contains glucosamine sulphate and chondroitin.These are the constituents of synovial fluid. These
supplements are known to improve pain in knee joint.Meanwhile you can also try other methods like
physiotherapy,weight reduction (if you are obese).Best wishes and regards!
