Webster and Feller reported a short version of the ACL-RSI scale (anterior cruciate ligament return to sport after injury). The authors are from OrthoSport Victoria and La Trobe University in Melbourne, Australia.

Patient selection: status post anterior cruciate ligament reconstruction surgery



(1) nervous about playing sport

(2) frustrated when considering knee with respect to sport

(3) afraid of reinjury if play sport

(4) confident that can play sport without concern for knee

(5) confident that can perform at previous level of sport participation

(6) think that it is likely that the knee will be reinjured by participating in sport


Negative items: 1, 2, 3, 6 (no or not responses given maximum points)

Positive items: 4, 5 (full confidence given maximum points)


Scoring for each item from 0 to 100 in 10-point increments (essentially a 10 cm VAS).


final score =

= SUM(points for all 6 items) / 6



minimum score: 0

maximum score: 100

An athlete who returns to sport tends to have a higher score.

A score >= 60 is associated with return to preinjury level of performance.

A score < 39 is associated with not returning to sport.



The area under the ROC curve is 0.75.
