The Medical Side of ACL Recovery: Dr Travis Brown

Dr Travis Brown is a pathologist and co-host of the This Medical Life podcast. He doesn’t specialise in ACL injuries, but he knows plenty about what can go wrong after surgery. This conversation covers the medical stuff that matters during recovery: why they tell you to keep your scars clean, what blood clots actually are, and how to know if something’s wrong.

Travis explains why tendons and ligaments take so long to heal compared to muscle (it’s the blood supply), what happens if you use a tendon from a dead body instead of your own, and why staph infections are dangerous near surgical sites. He breaks down what blood clots do to your body, how immobility after surgery increases your risk, and why leg swelling is the main warning sign to watch for.

The conversation keeps it practical: what waterproof bandaids actually do, why you take blood thinners, and what that yellow stuff means if you see it on your scar. If you’re recovering from surgery or about to have it, this episode gives you the medical knowledge to understand what your body’s doing and when to worry.

Key insights:

• Tendons and ligaments heal slowly because they have poor blood supply compared to muscle. That’s why ACL recovery takes months, not weeks.
• Using your own tendon for ACL surgery works better than using one from a cadaver. Your body repairs it over time regardless, but recovery is smoother with your own tissue.
• Keeping surgical scars clean matters because you’ve created an artificial track into your joint. If infection gets in, it can cause septic arthritis, which is serious.
• Blood clots form when you’re immobile after surgery. They block blood flow, which starves areas of oxygen. One-sided leg swelling is the main sign to watch for.
• Orthopedic patients automatically go on blood thinners because the surgery plus reduced mobility increases clot risk significantly.
