'injected directly'

Viscosupplementation is a procedure in which a thick fluid called hyaluronate is injected into the knee joint. There are no cures for osteoarthritis, so viscosupplementation will not cure osteoarthritis of the knee. However, it is thought that hyaluronate will improve the lubricating properties of the synovial fluid, reduce the pain from osteoarthritis of the knee, improve mobility, and provide a higher and more comfortable level of activity.

Male circumcision is an operation to remove the foreskin that covers the tip of the penis. The functions of the foreskin include protecting the head of the penis and contributing to sexual sensations. While recent research suggests that circumcision may bring some medical benefits, some doctors believe these are too small to justify surgery. A medical circumcision is a circumcision performed to treat a disease, such as pathological phimosis (lichen sclerosis), recurrent balanitis or recurrent urinary tract infections. A request circumcision is a circumcision performed for non-medical reasons, such as parental preference, religious reasons or to potentially prevent disease at some future time.There are different methods of circumcision. Either local or general anaesthesia should always be used. The procedure involves numbing the area with local anaesthetic creams or injection. A bell-shaped instrument is inserted under the foreskin to separate it from the penis. The foreskin is then removed using scissors or a scalpel. Alternatively, circumcision can be performed as a formal surgical procedure, using dissolving sutures or tissue glue.
