Hello, satucha-ga!
The following references reveal that Hyaluronic acid can indeed be
helpful for arthritic knees.
From the "Arthritis Foundation Statement on Hyaluronic Acid Treatment
for Osteoarthritis of the Knee."
http://www.arthritis.org/resources/news/Hyaluronic_Statement.asp
Summary
"Hyaluronic acid (currently marketed under the brand names Hyalgan,
Synvisc and Supartz) is an FDA-approved treatment for the relief of
pain in osteoarthritis (OA) of the knee. Treatment involves a series
of injections given directly into the knee joint."
"The Arthritis Foundation believes that hyaluronic acid provides
doctors and patients another option for treating OA, a disease that
can be painful and difficult to manage. It should be considered for
people with OA of the knee who have not responded well to exercise,
physical therapy and simple, over-the-counter (OTC) analgesics, such
as acetaminophen and ibuprofen. Hyaluronic acid also may be
considered for individuals who may be at risk for upper
gastrointestinal (GI) or kidney complications.

"Clinical experience and studies of the two hyaluronic acid products
available, hyaluronan and hylan G-F 20, are inconclusive but seem to
indicate beneficial effects with minimal adverse reactions in a
significant number of patients. The exact indications for
viscosupplementation are still evolving, but it currently can be
considered for use in patients who have significant residual symptoms
despite traditional nonpharmacologic and pharmacologic treatments."

"Some hyaluronic acid is already in the fluid in your joints. In
people with osteoarthritis, the hyaluronic acid gets thinner. When
this happens, there isn't enough hyaluronic acid to protect the joint.
Injections can put more hyaluronic acid into your knee joint to help
protect it."
"Hyaluronic acid injections may give you more pain relief than oral
medicines. These injections can help the pain stay away for 6 months
to a year, sometimes longer. Unfortunately, these injections don't
help everyone."
"Hyaluronic acid injections are also expensive but many health
insurance programs cover them. Hyaluronic acid injections may be an
option for you. Your doctor will talk with you about the pros and cons
of hyaluronic acid injections and whether they are right for you."
