Twelve weeks is a number, not a deadline.
Every runner who walks into the consulting room with patellar tendinopathy will, at some point, ask the same question. How long? They expect a number. They expect six weeks. Some are willing to be told eight. They are almost never told the truth, which is that the tendon does not care what week we are in.
Tendon adaptation is a slow, biological process. It does not respond to deadlines, to a half-marathon four weeks away, or to a coach who is impatient. Heavy-slow-resistance, performed three times a week, in pain and beyond pain into protected discomfort, is the cornerstone. The numbers in the published trials say twelve weeks is when most tendons begin to show meaningful change. But "most" is a population statistic and the patient in front of us is one person.
What follows in this issue is three case studies — a thirty-four-year-old ultra-runner, a fifty-one-year-old half-marathoner returning after a long break, and a seventeen-year-old high-school athlete with bone-stress on a too-fast progression. None of them recovered in six weeks. Two of them are running again. One is not yet.
If you are reading this with a tendon that hurts, the practice is on Botany Road, the diary is online, and we will tell you the truth about the time it will take.
