Where do these timelines come from?

The ranges reflect commonly cited figures from sports-medicine literature and consensus statements, such as Ekstrand's hamstring data and ACL return-to-sport reviews. They are population medians and 90th-percentile estimates, not guarantees for any individual.

Why is grade 2 hamstring so much longer than grade 1?

Higher-grade strains involve more muscle-fibre disruption, so the tissue needs longer to remodel and regain strength. Grade 1 is a minor strain returning in days to about 3 weeks, grade 2 typically takes several weeks, and grade 3 is a near-complete tear measured in months.

Is the ACL figure for surgery or conservative treatment?

The shown ACL timeline assumes reconstruction surgery followed by structured rehab, where 9 to 12 months is the broadly accepted minimum before sport. Conservative (non-surgical) management is sometimes chosen for low-demand activity and is not modelled here.

Can I come back faster than the typical figure?

Sometimes, but returning before strength, range of motion, and sport-specific function are restored sharply raises re-injury risk. Objective return-to-play criteria, not just elapsed time, should gate your comeback. Always clear it with your clinician.

Does this account for my age or fitness?

No. These are general population ranges. Age, prior injury, rehab quality, and the demands of your sport all shift the real timeline, which is why a clinician's individual assessment remains essential.

Returning to sport too early is a leading cause of re-injury. This estimator maps common injuries to published return-to-play ranges so you can set realistic expectations and plan your rehab around milestones rather than guesswork.

How it works

Each injury maps to two numbers drawn from sports-medicine literature: a typical (median) return in weeks and a longer-end estimate. Selecting an injury date projects those durations onto the calendar:

typical return date  = injury date + typical weeks
longer-end date      = injury date + upper weeks

The tool also lists stage milestones — for example pain-free walking, full range of motion, and return to running — that gate progression.

Notes

These are general ranges, not medical advice. Real recovery depends on injury severity, age, rehab quality, and your sport’s demands. Use objective return-to-play criteria and your clinician’s clearance, not elapsed time alone, to decide when to compete again.
