A User's Guide to Healthy Knees

Healthy knees require continuous motion. However, our generally sedentary lifestyles are at odds with the maintenance of robust knee joint architecture. Left motionless throughout large portions of the day, over time knee cartilage will break down and knee ligaments will become lax. These chronic changes are frequently associated with other degenerative alterations in knee joint architecture often resulting in pain in one or both knees. Increasing discomfort may cause a person to become even more inactive, creating a feedback loop of lower levels of activity and higher levels of knee pain. Paradoxically, the solution to many of these knee problems is to begin a program of progressive and rehabilitative activity that incorporates repetitive knee motion.

Continuous passive motion is a primary modality used in rehabilitation of knee mechanics following total joint replacement. Importantly, similar rehabilitative concepts may be applied in the management of many painful knees. The primary principle followed by such rehabilitation is "use it, or lose it." Healthy knees require a continuous flow of synovial fluid throughout the joint structure. This lubricating substance provides oxygen and nutrition to the knee joint, aids in shock absorption, and reduces joint friction. Inactive knees have diminished flow of synovial fluid throughout the joint structure, ultimately resulting in deterioration of joint surfaces and painful arthritis. Thus, surprisingly, chronic knee pain results from insufficient physical activity.

As is the case with every physiological process, activity creates a demand for nutrients. Biomechanically, increased motion increases blood flow, which provides oxygen and nutritional building blocks that are required for bearing weight and movement. Increased circulation also facilitates removal of metabolic waste, the byproducts of physical work. The entire process increases the robustness of the local system. Specifically, in the case of knee joints, increased workloads improve the capacity of the knees to do work, creating a new, positive feedback loop. As your knee joints adapt to increased activity, the physiological momentum shifts, in a sense, from a trend toward painful arthritis to a trend toward improved function, greater tolerance for physical loads, and diminished pain.

Beginning a daily walking routine will launch this entire process of knee rehabilitation. Start gradually, at a slow, comfortable pace, and walk for 10 minutes. After a few days, your body will begin to adapt and you will be able to gradually increase the duration of your walks. Add a minute or two every few days until you're walking a total of 30 minutes. Then gradually increase your pace, over a period of 3 or 4 weeks, until you're able to walk briskly for 30 minutes. Doing a brisk 30-minute walk 5 times per week will provide you with a substantial baseline from which to begin to pursue additional forms of exercise. Overall, for most of us physical activity is the best method for returning to good health.

Regular chiropractic care will provide significant assistance in your return to peak levels of health and physical performance. By detecting and correcting sources of nerve irritation and spinal joint dysfunction, regular chiropractic care helps ensure that your body is functioning at maximum capacity and protects your ability to get the most out of your exercise activities. In this way, regular chiropractic care helps you and all the members of your family obtain and enjoy ongoing health and well-being.

Testimonials

  • "Regular visits with Dr. Roeder have significantly reduced the frequency of migraines I have suffered and the amount of neck and shoulder pain I have lived with for years. Because of Dr. Roeder I am able to focus on my busy life again"
    S.L., San Diego
  • "This was my first encounter with a chiropractor and found the experience to be delightful, gratifying and well worth it! Instead of being given a bunch of pills and told to come back next week, the manipulation for my back and side injuries including carpal tunnel syndrome, responded very well to the treatments. Thank you, Dr. Roeder for a job well done"
    W.B., San Diego
  • "I came in originally for neck pain, but getting adjusted helped lower my blood pressure & my insulin levels too.Dr. Roeder is so thorough in her care-I never knew how much better I could feel.I no longer have to take blood pressure medicine now."
    A.W., San Diego
  • "Since meeting Dr. Roeder at a health seminar, she has changed my life, drastically-improving my health 100%. I had a wide range of symptoms, including chronic fatigue, constant and severe headaches, body aches, nausea, difficulty concentrating and I felt extremely tired and weak. She diagnosed me with having Fibromyalgia and Candida. She put me on an anti-inflammatory diet and started me on chiropractic treatment and instructed me on strength exercises. I have lost 40 lbs and feel fantastic! Whenever I eat something that sets off a symptom, I can identify the food source now. I know how to eat well and stay away from foods that cause inflammation. Had it not been for Dr. Roeder's expert care, I believe I would still be suffering from all those symptoms-- instead I feel fantastic!"

  • "My son was diagnosed at a very young age with Hyperkyphosis. The doctor told us that surgery would be his only option but we needed to wait until he got older.My husband and I were heartbroken to think about such a major surgery for our little boy.We wanted to help him anyway we could without doing surgery. We are so thrilled to say that after seeing Dr. Roeder my son's back has made a major improvement.That there is a stronger chance that he may not need surgery after all.My son is three now and he is a very active little boy and you can't even tell that he had ever had a bad back.He is able to do what all little boys do:run, jump and climb!Taking my son to Dr. Roeder was the best decision that me and my husband have made as parents.I am so happy that Dr. Roeder is part of our lives.In fact all of my extended family members are patients of her too!Thank you so much Dr. Roeder for all of your help.You have been such a positive part of our lives.You are part of our family."

  • "My daughter has been diagnosed with Von Willabrand's and Precocious Puberty at age 7. She had her first period at age 8, and it was for three days. The doctors said that her hormone levels were off and there wasn't any truly safe treatment. After talking to Dr. Roeder, she started chiropractic care to help her body cope better with this disorder and hopefully change her hormones. Now my daughter and I have been told by doctors at Children's Hospital that it looks like she won't be starting her period until two years from now-this will be the normal time when she should start! They told us to keep up the good work of whatever we have been doing because it seems to be working."
    J.H., San Diego
  • "I got treated for a neck and back injury that appeared to be chronic following a major car accident. I had been to chiropractors before but without much success.After seeing Dr. Roeder now though, my mobility and general feeling of well-being has greatly improved."
    C.H., San Diego
  • "Dr. Roeder was recommended by a friend and I am completely satisfied. I was having low back pain also some neck pain. My back feels better than it has in years. I feel Dr. Roeder is complete in recommending exercising and treatment!"
    M.L., San Diego
  • "I just wanted to say thank you for making me 'new' again. Also, for helping us through our tough times. You always have been nice to us and helpful when we were in your office-it was just like a second home! Every time I walked through the door I felt calm and relaxed. You always asked us how we were doing and how we have been. I thought that was very thoughtful and caring of you-especially considering that awful car accident we had been in. None of my doctors before had been as courteous as you. You have really made a bad experience into a great experience in a blink of an eye. I always loved that EVERYONE was always smiling! I wish that when I grow up I can be like you, always making people happy and feel better! Well, I think that you just made another patient happy because of your wonderful 'magic.' Oh and I know I already said this but I think I am speaking for everyone when I say: Thank you Dr. Roeder!"
