This study is about preventing osteoarthritis (OA), a common joint disease. It looks at how walking (daily steps) affects knee health after a surgery called anterior cruciate ligament reconstruction (ACLR). ACLR is when doctors fix the ligament in your knee. After this surgery, people often walk less, which might hurt their knee cartilage. Cartilage is the smooth tissue that helps your knee move easily. The study will check if walking more can make the knee healthier by using a special scan called MRI, which takes pictures of the inside of your knee.

Key Points:

• The study lasts 16 weeks and involves wearing a step counter.
• Participants must have had ACLR surgery 6-24 months ago and walk less than 7,000 steps a day.
• Compensation details and any risks are not mentioned, so consider asking about them if interested.
