Single-Leg Hop Test ACL
Single-leg hop tests compare operated and healthy leg jump distance and landing quality—core objective metrics before ACL return-to-sport clearance.
Single-leg hop test ACL batteries include forward hop, triple hop, crossover hop, and timed six-meter hop—comparing operated versus uninvolved leg distance and quality. Limb symmetry index above roughly eighty-five to ninety percent on distance and clean landing mechanics are common return-to-sport gates.
Pain, buckling, or valgus collapse fail the test even if distance looks acceptable. Perform when strength and ROM milestones are met, on non-fatigued days.
Common questions
-
What limb symmetry is needed on hop tests?
Many ACL protocols want eighty-five to ninety percent distance symmetry plus controlled landings. Quality and confidence matter—not distance alone.
