Arthritis is the medical term used to describe a disease affecting the cartilage within any joint in the human body. In other words, it is not a bone or ligament problem, but a condition in which the protective cartilage on the end of a bone that allows bones to move in relation to one another breaks down. As the cartilage becomes more diseased, a patient may begin to experience pain and stiffness in the affected joint. Get in touch with us today to see how we can help!

Our Patients Are Saying

“I had severe arthritis in my right knee and when I arrived at Dr. Kaper’s office without the ability to bend my knee. I had prior knee surgeries without good results and was anxious about having another one. After many years of pain, I woke up from surgery and the pain was gone... I am so grateful to Dr. Kaper and his amazing team for my great results.”
— J.G.

“Dr. Kaper quickly assessed the problem and laid out a course of action and got me back on my feet within less time than I could have imagined. I am very grateful to have had Dr. Kaper as my surgeon and coach, who made it possible for me to resume a normal life and enjoy the activities in my community.
— P.D.

Types of Arthritis



In OA, the cartilage protecting the bones of a joint wears down over time. OA is, therefore, commonly known as the “wear and tear” disease because it occurs much more frequently in older patients.


Rheumatoid Arthritis

The formation of rheumatoid nodules under the skin is usually indicative of RA, which tends to form over bony processes and frequently stressed joints. Although less frequent, RA can affect other parts of the body and cause subtle inflammation.


Juvenile Arthritis

A less common form of arthritis is Juvenile Arthritis (JA), which mirrors the symptoms of arthritis but occurs in patients under the age of 18.
