Managing Knee Osteoarthritis

Managing Osteoarthritis of the Knee

Osteoarthritis is a degenerative joint disease in which the cartilage and surrounding bone of an affected joint degenerates, causing pain and stiffness and often includes chronic low grade inflammation.   Osteoarthritis research has been commonly focused on the knees for good reason:  we load these joints (put weight on them) in daily movement.  Both repetitive and extreme positions can cause wear and tear on the joint and lead to the development of osteoarthritis.  While there is no cure for this condition, exercise can reduce disability and control the pain of knee osteoarthritis.  Both resistance training and aerobic exercise have been shown to help manage the symptoms and prevent further joint degeneration (Arthritis Society, 2015; Kravitz & Thomas, 2014).  Specifically, some moderate intensity and low impact forms of exercise such as walking, biking, water exercise and strength training can be particularly effective at building strength around the knee without causing further joint damage.  Research suggests that beginners should start slowly, and work to accumulating 150 minutes weekly of low impact cardiovascular activity (spread throughout the week).  In addition, two weekly sessions of strengthening exercise should be performed, focussing on the lower body muscles.  Those who are new to exercise should begin with exercise that is not weight bearing (such as gentle cycling or swimming) and progress to weight bearing activity (walking, strength training exercises performed while standing).  Stretches to reduce pressure on the knee joints should include both the calves and hamstrings.  To strengthen the muscles around the knees, try these two exercises:

Straight Leg Raise

Recline on your back on the floor.  Then, lift yourself up to support your upper body with your elbows. Bend your left knee and keep that foot on the floor. While keep the right leg straight and toes pointed up, squeeze your quadriceps muscles and raise your right leg, then lower it to back to the ground.  If it is uncomfortable or too hard to do this exercise on the floor, try it while seated on a chair.  Work up to performing two sets of 10 repetitions on each leg.

Chair Squats

Raise the seat of a chair with pillows or cushions so that you stay higher and experience less knee flexion (bend) for this exercise.  Begin by sitting on the chair with your back straight and your feet flat on the floor.  Squeeze your quadriceps and buttocks while slowly standing up.   Slowly lower yourself down again while contracting the leg and buttocks muscles again, until you are in a seated position.  Work up to two sets of 10 repetitions.
