ACL Return-to-Sport Criteria Test Battery

Calculate composite return-to-sport (RTS) readiness after ACL reconstruction using limb symmetry index (LSI) for strength (quadriceps/hamstrings), hop tests (single-leg, triple hop, cross-over hop), and psychological readiness (ACL-RSI). LSI >90% threshold for clearance.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate composite return-to-sport (RTS) readiness after ACL reconstruction using limb symmetry index (LSI) for strength (quadriceps/hamstrings), hop tests (single-leg, triple hop, cross-over hop), and psychological readiness (ACL-RSI). LSI >90% threshold for clearance

Each component has a specific meaning:

  • Limb symmetry index — The limb symmetry index recorded for the scenario being assessed.

Note: Interpret the acl return-to-sport result against the thresholds and context described above.

How to Use

Enter the limb symmetry index for the scenario you are assessing. Calculate composite return-to-sport (RTS) readiness after ACL reconstruction using limb symmetry index (LSI) for strength (quadriceps/hamstrings), hop tests (single-leg, triple hop, cross-over hop), and psychological readiness (ACL-RSI). LSI >90% threshold for clearance. Use the acl return-to-sport result to inform your calculation.
