Study Finds High-Impact Exercise Halves Hip Replacement Risk in 18,000 Arthritis Patients

Summary
Nearly 18,000 people with hip or knee arthritis were tracked in a new Danish data study, which found high-impact exercisers with hip arthritis had about half the hip replacement rate within a year.
About 6% of participants did high-impact activities such as running, tennis and skiing, and those with knee arthritis were no more likely than others to undergo knee replacement.
The study, published in the British Journal of Sports Medicine, challenges the common view that impact exercise inevitably worsens arthritic joints and suggests some loading may help strengthen hips.
Researchers and outside experts cautioned the findings come from an observational study, so people who kept running may already have had milder arthritis; the study also did not identify how much impact exercise is optimal.

Rethinking Osteoarthritis: How Exercise Lowers Arthritis and Hip Replacement Risk
Overview
This report highlights a major shift in how osteoarthritis is understood and managed. Traditionally seen as a 'wear and tear' disease where joint use led to deterioration, new evidence shows that joints actually benefit from regular use. Experts now emphasize that staying active and strengthening muscles are crucial for joint health, leading to less pain and better movement. Instead of avoiding activity, appropriate exercise is now seen as a key strategy for managing osteoarthritis, challenging old guidelines that recommended reduced activity. This evolving perspective supports a more active and individualized approach to arthritis care.
