Exercises for an Inflamed Knee

Inflammation of the knee can be caused by a number of reasons, including trauma or injury, the onset of arthritis, osteoporosis, or bursitis. Common symptoms of knee inflammation include tenderness, swelling and a warm feeling around the knee area. Although the pain may range from slight to mild discomfort, doctors may recommend physical therapy to strengthen the knee, which can reduce the risk of future knee injuries. Do not attempt the following exercises without your doctor's permission or supervision by a physical therapist, as you can worsen the condition or cause severe damage.

Leg Raises

• Strengthening exercises are used during physical therapy to improve the quality of your knee, according to physical therapist Jim Johnson, author of "Treat Your Own Knees." The exercise sessions usually involve weight placed on your ankle, followed by lifting your leg up and slowly moving it back to the starting position. This exercise is repeated for two sets, 15 repetitions per set. As you continue your physical therapy, your therapist will increase the repetitions and weights.

Swimming

• Swimming, which also can build strength in the knee and is usually included later in physical therapy sessions, relieves inflammation by loosening the joints and increasing your range of motion, according to Johnson. Swimming is also considered a form of cardiovascular exercise, which helps improve circulation. Your physical therapist may have you swim a few laps while gently kicking in order to get accustomed to the movement. More exertion will be allowed as your knee strength and mobility increase.

Stretching

• The most important exercise for an inflamed knee is stretching. According to Susan Bernstein, author of "The Arthritis Foundation's Guide to Pain Management," stretching for at least 10 minutes a day can reduce muscle soreness and improve performance during exercise.

  Johnson suggests you sit on the floor with your legs closed and gently extend your upper body forward as if you're trying to touch your toes. Hold this position for 10 to 60 seconds, rest and repeat. Be sure to stretch before and after exercising to improve flexibility.
