Return To Play Timeline Calculator

Work out return to play timeline instantly with clear inputs, formula shown and shareable results.

About Return To Play Timeline Calculator

Return-to-play timelines depend on tissue healing biology, so grade 1 strains typically resolve in about two weeks while grade 3 tears take three months and surgical repairs six to nine. Recovered pain-free range of motion is used here to adjust the estimate, but real clearance should always be criteria-based rather than calendar-based.

Formulas

Baseline timelines

grade 1 about 14 days, grade 2 about 42, grade 3 about 90, surgical about 210

Adjustment

scaled by pain-free range of motion regained

Worked example

With the default values below, Return To Play Timeline Calculator returns Estimated Days Remaining of 34. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
This is a general timeline estimate from published averages, not medical advice or a clearance decision. Return to play must be authorised by a qualified clinician after criteria-based testing. Timelines vary widely between individuals and injury sites.

Frequently Asked Questions

Why is criteria-based return better than time-based?

Because healing rates vary widely. Strength symmetry, hop tests and sport-specific movement quality predict re-injury far better than elapsed days.

What is the biggest re-injury risk factor?

Returning before strength deficits have resolved. Even a 10% side-to-side deficit substantially raises re-injury rates.
