Tai chi can be a useful exercise option for some people with knee osteoarthritis, but it is not a cure and does not prevent arthritis from developing. Its value comes from controlled movement, balance practice, lower-body strengthening, and continued physical activity—not from “healing energy” or restoring damaged cartilage.
What does the evidence show?
NCCIH summarizes research showing that tai chi can improve pain, stiffness, physical function, and balance in people with knee osteoarthritis. The American College of Rheumatology and Arthritis Foundation have strongly recommended tai chi as one exercise option for knee and hip osteoarthritis.
Benefits are not unique to tai chi. Strength training, walking, aquatic exercise, physical therapy, and other appropriate forms of activity may also help. The most useful program is one a person can perform safely and consistently.
How tai chi may help
- Slow weight shifting challenges balance and lower-limb control.
- Partial-knee-bend positions can strengthen the legs when tolerated.
- Gentle repeated motion may help maintain comfortable range of motion.
- Low-impact practice can provide activity without running or jumping.
Modify around painful joints
- Use a shallower stance if deeper knee bending increases pain.
- Shorten steps and reduce twisting if balance or joint control is limited.
- Use a chair, wall, or rail for support.
- Avoid forcing the knee through sharp pain, locking, or instability.
- Increase practice gradually rather than assuming more is always better.
When to seek guidance
Ask a clinician or physical therapist about exercise if you have a recent joint replacement, significant swelling, unexplained instability, severe pain, repeated falls, or another condition that changes what movements are appropriate. An experienced instructor can then help adapt the form around those restrictions.
