Dr. Joseph F. Zabilski: I see a lot of people with arthritis in the knee and I get a lot of questions about what treatment options may be for them. Usually, what I tell them is that it depends on the degree of arthritis they have. For mild-to-moderate arthritis, oftentimes just taking over-the-counter medication might help or possibly taking a prescription medication such as an anti-inflammatory or Tylenol. If it gets a little worse, sometimes we will try other treatment modalities including injections, possibly a cortisone shot or physical therapy. There is also a type of a lubricating shot that sometimes can be helpful for mild-to-moderate arthritis. If it does get to the point where these things are not helping, then sometimes surgery is an option and that would really depend on the degree of arthritis they have, the degree of symptoms, how much pain they are in and how it affects their activity levels. One thing we do have here that is helpful is we do have options to provide all of these treatment modalities including medication, cortisone injections or other types of injections as well as physical therapy.
