A few months ago I had a fairly bad skiing accident where I had a lot of pain on the inside of my right knee when walking and swelling and tightness. Due to insurance issues, I wasn't able to see a doctor until 2 months after the injury at which point the pain was 80% gone. From physical testing, she said it was likely an MCL tear and possible meniscus tear (no x-rays or MRI done). I didn't do anything special beyond regular physical activity. Now, 6 months after the injury, my knee feels normal again.
Am I at a higher risk for early onset arthritis? What do I need to do to lower my risk going forward?
