Study Reveals How Small Changes in Walking Technique May Help Treat Knee Osteoarthritis
Adjusting foot angle reduced knee loading by 4% and pain by 2.5 points on a 10-point scale in patients with mild to moderate osteoarthritis, study finds.
- A study led by NYU Langone Health, the University of Utah, and Stanford University, published in The Lancet Rheumatology, found that small foot-angle adjustments during walking may alleviate knee pain and slow osteoarthritis progression.
- Nearly a quarter of people over 40 experience painful osteoarthritis, which degrades cartilage and is managed with pain relievers, physical therapy, or surgery.
- Participants who modified their gait reduced maximum knee loading by 4%, while those with normal gait increased loading by more than 3%, study found.
- Tailoring each patient's foot angle may alleviate symptoms long term and could help delay surgery, Valentina Mazzoli said, although results need confirmation.
- Future studies will test whether tools using mobile sensors like smartphone video and a 'smart shoe' can identify effective walking methods, Uhlrich said.

The No. 1 Walking Change That Can Help You Delay a Knee Replacement
Nearly 900,000 Americans undergo knee replacement surgery each year, according to Cleveland Clinic.

When someone gets a knee replacement earlier in life, there’s also a better chance they’ll nee…
How small changes in walking technique may help treat knee osteoarthritis
Gait analysis and pain measures show that subtly adjusting the angle of the foot during walking may reduce knee pain caused by osteoarthritis. This approach may also slow progression of the condition, an incurable disease in which the cartilage cushion inside a joint breaks down.
