knee arthritis


  • Arthritis is the most common cause of disability
  • Osteoarthritis is the most common form of arthritis
  • Osteoarthritis affects over 27 million individuals around the world


Arthritis is inflammation of a joint. Joints are found everywhere in the body where two bones meet. There are many forms of arthritis however the most prevalent form is Osteoarthritis (OA).

OA is commonly referred to as wear-and-tear arthritis because it occurs when cartilage between joints wears down over time. Cartilage provides cushion between bones allowing for frictionless movement. If the cartilage wears down enough bone may rub on bone. OA most commonly affects joints in the neck, hands, lower back, knees and hips; this can damage any joint in the body. As time progresses osteoarthritis worsens. There is no cure for OA, however there are treatments available to help relieve pain associated with arthritis. These treatments help to improve joint function, and even slow the progression of the disease.


There are over 100 forms of arthritis. The three most prevalent types of arthritis are:

  • Osteoarthritis (OA)
  • Rheumatoid arthritis (RA)
  • Juvenile Arthritis (JA)


The symptoms experienced with OA generally develop slowly and worsen over time. Symptoms of OA include:

  • Pain
  • Stiffness
  • Tenderness
  • Grating Sensation
  • Loss of Flexibility

If you are experiencing joint pain or stiffness that persists for over a few weeks, it is recommended that an appointment be made with a physician.


A physical examination of the affected joint(s) will be done to check for swelling, tenderness, or redness. The joint’s range of motion may also be examined. If necessary, imaging and lab tests may be ordered by the physician. Imaging test will take a picture of the joint. These images are achieved through an X-ray or Magnetic Resonance Imaging (MRI).


Osteoarthritis is a progressive disease that occurs when the cartilage cushioning the ends of bones deteriorates. There is no known cause however there are certain factors that increase an individual’s risk of developing OA. These factors include:

  • Age: risk of developing OA increases with age
  • Gender: women have a higher risk for developing OA compared to men
  • Weight: carrying more weight puts stress on joints


Although there is no cure for OA, there are treatments available to help relieve the pain associated with OA.

  • Nonsteriodal anti-inflammatory drugs (NSAIDs), acetaminophen or narcotics for severe pain
  • Cortisone shots
  • Lubrications shots
  • Osteotomy or realignment of bones for OA in knee joints

Excellent!!! During my first visit with Dr. Crooks he had already reviewed my MRI, previous doctor notes, and images. I felt very welcomed with Dr. Crooks and Ramona his nurse! They are both very knowledgeable and caring! My pain is in my cervical area, Dr. Crooks and I disgusted my treatment plan and he thoroughly explained everything to me. I just moved to Arizona from Florida and he has been an excellent Physician! I received a few injections, due to being terribly in pain on my first office visit. I was able to schedule my procedure 2 days later. I was so thankful to have it scheduled! He is truly an amazing Doctor! I would definitely recommend Dr. Crooks! I felt he treated his patients as if they were his own family. He actually took the time to discuss what concerns you have, and what he recommended, and could help with. I am a patient at the Scottsdale office and the staff was very helpful as well. I can not say enough good things about Dr. Crooks! Ramona also was a very sweet, caring, and a magnificent Nurse. She took her time with you as well and I never felt rushed or as if they were to busy to take on a new patient. Definitely an outstanding and wonderful Doctor!

Matthew "Dr. Miracle-worker" Crooks was my latest attempt since 2002 of four other "back specialists". Matthew having studied my previous MRIs decided that RFA was the most likely treatment for success while being the least invasive. He setup an aggressive schedule and only 3 days ago I had my first Lumbar right side RFA. His staff have the process down to a very quick 15-30 minute procedure (although with sedation I remember nothing from when Matthew came in the room until just before my wife drove me home). In total honesty the very next morning is the first time in ten years that I have had NO pain at all, easily stood up straight and wasn't grasping for every wall or counter top as had become normal when attempting to walk. Having not used sedation for the test procedures I know that the scheduling, preparatory, procedure and followup staff were very polite and fun yet super professional at their jobs. After 3 days I am feeling random Lumbar area pain in specific locations, duration, and intensity as the nerves fight their eventual desensitizing of 12-18 pain free months! Danielle, Juliet, Romona, Jay, Kathy, Danny, and Dr. Miracle Worker (and anyone I missed) - MANY THANKS!!

I can not say enough good things about Dr Crooks and the Pinnacle Pain Staff/Team. I had back pain for nearly 3 years and Dr. Crooks has given me the ability to a full night sleep after my procedure. I was hesitant at first as I fear injections but the staff and Dr Crooks do such a great job at making me feel better. I greatly appreciate his time and consideration, he is a very caring person and a GREAT physician. I highly recommend PPSC- Thank you Dr Crooks!!!!

I came to Dr Crooks with a number of issues which prevented me from living a full and enjoyable life. In a few months Dr Crooks has me back on the golf course, bending over to wash my face and able to lift my leg enough to pull slacks on. I had almost given up thinking I’d ever be able to perform any of these simple tasks and can’t put into words how happy I am every day. Thanks Dr Crooks.
