20:This Knee Injury Ends a 400-Day Run Streak… But Surgery Isn’t the Answer?

What happens when a lifelong runner is forced to stop just short of a 400-day streak? In Episode 20 of Interdisciplinary Case Miles, a real case highlights the challenges of a 52-year-old runner dealing with a degenerative medial meniscus injury and the decisions that follow when running is part of your identity.

This episode covers how these injuries present, what imaging like MRI actually tells us, and why physical therapy is often just as effective as surgery for long-term outcomes. You’ll hear how biomechanics, strength, and running form all influence knee stress and what can be adjusted to stay active without making things worse.

There’s also an important conversation around nutrition and long-held beliefs in running culture, including the risks of underfueling and the pressure to chase an “ideal” race weight.

For many experienced runners, habits built over decades can become the very thing that increases injury risk. Whether you're managing knee pain, coaching athletes, or working in sports medicine, this episode offers practical, evidence-informed strategies to support recovery and longevity in the sport.
