Return to Sport After Injury: Why the Clock Is the Wrong Metric
"Six weeks and you're good to go" is one of the most dangerous phrases in sports medicine. Time is a proxy for healing, not a guarantee of readiness. Here's what objective return-to-sport criteria actually look like.

When someone asks 'how long until I can play again?', the honest answer is 'we don't know yet — it depends on how you respond to rehab and whether you can meet objective criteria.' That's not the reassuring answer athletes want, but it's the only accurate one.
The Problem With Time-Based Clearance
Healing timelines are population averages. Individual variation is enormous, driven by age, fitness, nutrition, sleep, stress, and the specific injury pattern. Two athletes with the same ACL reconstruction may differ by 3–4 months in their actual readiness. Clearing both at 9 months because 'that's the protocol' will over-protect one and under-protect the other.
What Objective Criteria Look Like
At Stance, return-to-sport clearance for lower limb injuries involves a structured test battery across three domains:
- —Strength criteria — Limb Symmetry Index ≥90% for quad and hamstring peak torque, tested with VALD Dynamo
- —Functional hop tests — single-leg hop, triple hop, crossover hop, and 6-metre timed hop, all ≥90% LSI
- —Movement quality — video-based movement screening assessing landing mechanics, trunk control, and joint alignment under fatigue
- —Psychological readiness — validated questionnaires assessing fear of re-injury and confidence in the joint
Psychological readiness is often the last criterion to be met — and the most commonly overlooked. Fear of re-injury significantly increases actual re-injury risk.
The Role of Progressive Exposure
Return to sport isn't a binary event — it's a continuum. We structure it in phases: return to training (full team sessions without contact), return to competition (non-contact phases of matches), and unrestricted return (full contact, full competitive load). Each phase has its own criteria and monitoring checkpoints.
What This Means for You
If you've been injured, push your team to give you objective targets, not just a date. Ask: 'What do I need to demonstrate to be cleared?' The answer should be specific numbers and movement standards — not 'you should feel ready by then.'
