1. Three factors play a role in knee pain: structural, biomechanical and environmental. Structural means damage, biomechanical means abnormal tracking or loading within a joint or tendon because of misalignment, weakness, and/or inflexibility. Environmental typically means inflammation within the joint or tendon. When formulating a treatment plan for you, we typically want to address one or two of these factors initially. Unless you have major damage, we’re normally not treating structure initially, as that results in a surgery.
2. Age often plays a role in these different factors: in the absence of injury, in patients under 20 years of age, the problem tends to be biomechanical. In patients ages 20 to 40, the problem tends to be biomechanical and inflammatory. In patients older than 40, structural, biomechanical and inflammatory are typically all playing a role.
3. Being proactive in the care of your knee problem usually produces better outcomes than being reactive. This means integrating treatments early on and not waiting until you have major pain or disability to see a physician. We term this “PIO,” Proactive Interventional Orthopedics.
4. Meniscus tears are commonly found on MRIs and may or may not be a source of pain. For decades, the trend was to treat these surgically, typically arthroscopically, removing the torn piece of meniscus. There’s now a trend towards repairing the meniscus tear when possible, but only about 10% can be successfully repaired. Thus, surgery for meniscus tears, especially those age 40 and above, is falling out of favor. On occasion, surgery is the better choice, but treating these initially nonsurgically is usually the best way to start. We often tell patients “a little torn meniscus is better than less meniscus,” especially long term. Less meniscus often equals greater arthritis.
5. Three types of injections can be used for most knee problems: steroid, hyaluronic acid, and orthobiologics. Orthobiologics include platelet-rich plasma (PRP) and stem cell injections. Each of these injections can be reasonably good choices, but for long-term success, PRP is likely your best option in terms of producing favorable outcomes, modifying the disease process, and these are often the most cost-effective option. Stay away from “stem cell” injections that are ordered by physician’s or chiropractic offices and do not come from you own bone marrow or fat. These are often being used inappropriately, and patients are charged exorbitant amounts of money to have these injections.
