What score at 6 months on the single leg hop for distance will be predictive of successful outcomes at 1 year?

What score at 6 months on the single leg hop for distance will be predictive of successful outcomes at 1 year?

• A. 80% of CL limb
• B. 88% of CL limb
• C. 90% of CL limb
• D. 85% of CL limb

Answer: (B)

The test is about using early functional recovery to predict longer-term success. In the single-leg hop for distance, how the operated leg compares to the healthy leg is captured by the limb symmetry index (LSI). Reaching near-equal performance by six months reflects adequate power, neuromuscular control, and confidence, all of which are linked to better outcomes a year later. Specifically, achieving about 88% of the contralateral limb at six months has been shown to best predict successful outcomes at one year. It strikes a balance: not so lenient that many who won’t do well are counted as success, and not so strict that many who will go on to be fine are unnecessarily delayed. So the 88% threshold is the most reliable predictor among the options provided, indicating that a patient has regained sufficient functional symmetry to anticipate favorable longer-term results.
