Every Johor runner we see after a knee injury asks the same question: "When can I run again?" The honest answer is: it's not about the calendar.
It's about whether you can pass a specific set of tests.
Going back by calendar ("it's been 6 weeks, I'll try a short run") is why so many runners get reinjured.
The tests that actually matter
For most post-injury or post-surgical knees, a physio looks for these thresholds before clearing running:
- Strength: at least 70–80% of the uninjured leg's strength (measured with specific tests).
- Single-leg squat: clean form, no valgus collapse, full range.
- Single-leg hop: at least 85–90% of the uninjured leg's distance.
- Hop pattern: able to do 10 single-leg hops without pain or noticeable asymmetry.
- Pain during testing: none or minimal.
If you can pass all of these, running is ready. If you can't, running is going to cost you a setback.
What a return-to-run programme looks like
Start with walk-run intervals, not continuous running. A typical first week: 5 × (2 min walk + 1 min run).
Progress to more running, less walking, over 4–6 weeks. Running on soft surfaces (treadmill, grass at Iskandar Waterfront) first, concrete later.
Volume progression: add no more than 10% per week. If pain returns, drop volume by 30% for a week, then rebuild.
What to avoid
- Skipping criteria testing and running on "hope."
- Going back to a parkrun or race without a build-up.
- Running through new pain. Pain during running that is worse than 3/10 means stop.
- Ignoring the uninjured leg - it often has deficits too after a long layoff.
Johor context
We work with many recreational runners - parkrun at Legoland Merlin, Iskandar Waterfront runs, club runners preparing for Singapore marathons who use JB trails.
We plan rehab around your running goals and often coordinate with Singapore-based coaches if relevant.
