It’s Time To Start Treating Your Arthritic Knee Like Your Car

“Orthopedic Maintenance”…that’s a term you may start to hear, especially in our practice. For years, patients have been led to believe that in the case of their arthritis, there’s “nothing you can do about it” until you want or choose to have a replacement. Also, our medical system has been developed to be reactive instead of proactive, especially again in the setting of arthritis. So, let me ask you this, do you only take your car to the mechanic when you have a problem? If the answer is yes, then you are on the fast track to either needing a new car or paying your mechanic a pretty penny for all the repairs your car will need! If you are a wise car owner, then you take your car in at regular intervals for the oil change, fluid additions, tire rotation, alignment, brake maintenance, and various inspections. So I then ask, should you be doing the same for your arthritic knee? The answer is a resounding “Yes!”

So, what does orthopedic maintenance look like? In very general terms, it means that if your body has aches, pains, or dysfunction, then it’s wise to jump on these earlier than later, avoiding the temptation to ignore symptoms, and think, “I’m just getting old.” This translates to seeing your orthopedic/sports medicine physician confirm a diagnosis and discuss treatment and prevention strategies. Let’s focus on one of the most effective forms of non-operative treatment for knee osteoarthritis: injections

1) Steroid (cortisone) injections are great for acute pain when it’s important to reduce symptoms and swelling quickly. Steroids are really a more “reactive” treatment, such as when a patient needs to feel better quickly for a major life event (a trip, visit with the grandkids, have to feel better for work, etc.) but can be proactive for a patient trying to stave off a knee replacement or is not a good candidate for knee replacement. For example, for an elderly patient whose risk of knee replacement outweighs the benefit, planning two steroid injections a year for his/her symptomatic knee arthritis may allow the patient to feel less pain, move better, be at lower risk for a fall and have a greater quality of life.

2) Hyaluronic Acid/Viscosupplement injections (brand names include Orthovisc, Gelsyn, Euflexxa, etc.) have a long track record of excellent safety and provide symptomatic relief in approximately 75% of patients for 4-12 months. They probably work as anti-inflammatories and lubricants for the knee, replenishing the hyaluronic acid in the arthritic knee that is depleted or less effective. These are probably more beneficial for those with mild to moderate arthritis as opposed to more severe cases. There are essentially no side effects except for mild injection-site soreness in some. Most insurance companies will authorize this 3-4 injection series every 6 months, so planning on about two series a year is a very proactive strategy. These are what we often term the “oil change” injections.

3) Orthobiologic injections are really your “game-changer” injections. These have been used in orthopedics for 15 years and in our practice for over 10 years. Platelet-Rich Plasma (PRP) is the most commonly used orthobiologic injection. Insurance companies and even some medical providers still like to consider these as “experimental” or unproven treatments for osteoarthritis, yet there are now 39 randomized, controlled trials (studies) that demonstrate that PRP is effective in the treatment of knee osteoarthritis. PRP is derived from your own blood, as we obtain blood from an arm vein, spin this in a centrifuge, remove the majority of red and white blood cells, and concentrate the platelets which are rich in your own growth factors. These growth factors module inflammation, reduce pain, improve function, and most likely have a beneficial effect on the cartilage within the joint. This is how they are “game-changers.” They very likely stop or slow the progression of arthritis by stabilizing the cartilage and potentially improving the quality of the cartilage.

We typically start with two PRP injections 2-6 weeks apart and expect, on average, 6-12 months of symptomatic benefit. Repeating these at regular intervals is likely the best plan of action in order to see continued, long-term benefits. PRP injections are here to stay, and how we continue to apply them in the treatment of osteoarthritis will continue to evolve.

Primary care providers and dentists have done a great job integrating maintenance evaluations and treatments into a patient’s health regimen. Now, we should likely be doing the same in orthopedics, and the treatment of knee osteoarthritis is a great place to start, as this is the most common medical condition seen in our office today. It is a tremendous source of pain and disability for millions of Americans and contributes to the spending of billions of health care dollars. It’s time for orthopedic physicians and patients to join together to be proactive over-reactive and realize that less-invasive preventative strategies are preferred over more invasive and costly interventions.

As always, we are here to help and strive to be your resource for these innovative maintenance strategies!
