Pain, swelling and stiffness in the knee and an inability to use the joint as much as desired.
What’s Going On In There?
Arthritis is simply the wearing out of a joint’s lining, leaving bone to grind on bone. It’s caused by a combination of factors, including old injuries, genetic predisposition, overuse and sometimes just bad luck.
Arthritis gets worse over time, but it’s possible to continue at your current level of fitness. Find ways to train and maintain fitness while reducing the wear and tear on your knees.
Build super legs. If you rest or scale back on your activity level, you lose muscle and the condition worsens. I suggest biking and swimming to build leg strength. Quad-, hip- and glute-strengthening exercises are musts. Multidirectional lunges as well as squats, squat jumps and squat thrusts once you’re able to do them are all good muscle builders.
Fix foot mechanics. Pronation (when the foot turns inward as it strikes) puts extra pressure on the knee joint. Arch supports and stability shoes can help relieve excess knee pounding. Also, try to shorten your stride and raise your foot strikes to 90 per minute.
Try supplements. There is not scientific data to prove the benefits, but many of my patients report that glucosamine and chondroitin help with arthritis pain.
Try an NSAID. An anti-inflammatory like ibuprofen or naproxen can help with pain and swelling.
Change the conditions. If possible, switch to a softer running surface. Blacktop is softer than concrete, dirt and grass are softer than blacktop, and the all-weather track is best of all.
When To Call A Doctor
If you suspect you have arthritis in your knee, it’s a good idea to see a sports doctor, who can verify it easily with an X-ray (which is a better diagnostic tool for arthritic joints than an MRI). A full-on assessment of biomechanical factors such as strength, flexibility and foot mechanics, as well as of external factors such as shoe type, running surface, bike fit and training regimen, can be a huge help.
A doctor can also administer more aggressive treatments if warranted. For example, prescription anti-inflammatories and injectable forms of hyaluronic acid (a substance that occurs naturally in cartilage and helps cushion joints) can help alleviate symptoms.
Last, since arthritis is a degenerative condition, it’s a good idea to see a doctor early in its course to establish a baseline for your condition. Your doctor can use it to assess later changes as he or she continues your care.
Do You Need Surgery?
Generally, no. As you get older, however, knee replacement surgery may be an option if your condition no longer responds to regular therapies.
