Is Running Truly Bad for Your Knees? The Age-Old Question Addressed.

You may have heard the phrase “running is bad for your knees” at some point in your running journey, whether it was from a friend, magazine, media outlet, or even a seasoned healthcare provider. Running essentially puts loads of stress through your ankle, knee, and hip joints. It would naturally make sense to think that the sport could lead to higher incidences of degenerative and arthritic conditions.

I have treated several patients who are over the age of 50 and are recovering from all sorts of orthopedic conditions including knee, hip, and ankles surgeries. Unfortunately, most of them begin the physical therapy journey with the already pre-conceived notion that they will forever have to forego some of the recreational activities that they used to enjoy, such as running, hiking, or even CrossFit. I will be the first to admit, a post-surgical hip or knee maybe never be 100% that of the “good” leg, BUT this does not mean that you have to completely eliminate high intensity activity from your life.

This last month, one of my patients “Jim” who has been on the road to recovery from surgical repair of his knee and meniscus, just returned to attending CrossFit classes without pain! Jim is over the age of 50, has had chronic history of knee arthritis, pain and weakness. How did he do it?? Jim was diligent in completing his daily mobility and strengthening, and we created a detailed plan that outlined a gradual progression of return to sport activities while increasing the resilience of his knee joint. This type of success story is not just an outlier, but is actually backed by the literature in the research world as well!

A recent study in 2017 (by Lo et. al) of almost 3000 runners concluded that there is no increased risk associated with OA (osteoarthritis) when compared to non-runners in the community. In fact, some research articles have even proven that running has a protective effect on the knees, with less rates of arthritis compared to the general population. Another interesting study followed a cohort of runners over age 50 with already existing knee osteoarthritis, with check in visits and X-rays at 48 and 96 months. The researchers concluded that a “self-selected running pace” was actually correlated with no worsening of knee pain or worsening of joint damage seen by X-rays.

In short, running can be very healthy for you and your knees as long as you are increasing your total mileage and volume in a progressive fashion to avoid overuse type injuries. As stated above, a “self-selected pace” could mean that you are running walk/jog type intervals or avoiding hill runs for the time being as you work on improving leg strength and endurance. The standard rule of thumb in the sports rehab and running world is to follow the “10% rule” when beginning a new program or ramping up training. This will be covered more in our next running blog posts, so stayed tuned!

Our team here at Rehab United Seattle has decades of experience working with all types of runners and evaluating the body systems as an entire chain, instead of just looking to the knee as a source of pain. If you are currently dealing with nagging aches, pains, or tightness or are just looking to have your movement quality assessed, consider scheduling a visit with a PT or rehab professional. Addressing body asymmetries and mobility restrictions now, will pay dividends toward pain free running for the rest of the summer.
