Returning to running after knee surgery, week by week
A realistic twelve-week timeline from first steps to first run, and the milestones you need to pass before moving on.

Everyone asks the same question after knee surgery: when can I run again? The honest answer is that it depends on milestones, not dates. Here is the timeline we use at Oriel.
Weeks 1 to 2: swelling and range
Goal: full extension and 90 degrees of flexion, walking without a limp. Running is not on the agenda yet.
Weeks 3 to 6: strength
Goal: single-leg squat with control, step-downs without the knee collapsing inward. We measure quad strength against your other leg.
Weeks 7 to 9: impact
Goal: two-leg hops, then single-leg hops, pain-free and symmetric. This is the gate before running.
Weeks 10 to 12: run
Walk-run intervals on flat ground, building by no more than 10% a week. Most patients are running continuously by week 12.
Your timeline may be faster or slower. What matters is passing each gate, not the calendar.
