PMID 28941959WHAT IT FOUND
The Brazilian Portuguese versions of the ACL-RSI and ACL-QoL are reliable and valid for assessing psychological readiness and quality of life in patients after ACL reconstruction.
They can be used clinically to guide return-to-sport decisions.
Key findings
01The Brazilian versions of the ACL-RSI and ACL-QoL demonstrated good test-retest reliability with ICC values of 0.78 and 0.84 respectively.
02Internal consistency was good for the ACL-RSI (Cronbach's alpha 0.87) and excellent for the ACL-QoL (Cronbach's alpha 0.96).
03Construct validity was supported by significant correlations with established knee and health measures, such as the IKDC (rho = 0.58 for ACL-RSI; rho = 0.73 for ACL-QoL).

What it does not show
The study population was restricted to patients aged 16-50 who had already undergone reconstruction and were involved in sports, so results may not generalise to non-sporting populations or those with different injury profiles. The ACL-RSI subdomains (emotions, performance, risk assessment) are highly interrelated and cannot be scored separately, limiting the granularity of psychological profiling. The relatively short interval between test and retest (5-8 days) might not fully capture stability over longer periods, though it was chosen to minimise clinical change.
Declared interests
The authors declare no conflicts of interest.
The easy way to misread this
Do not assume the ACL-RSI can provide separate scores for emotions, performance, and risk assessment. The high internal consistency suggests these items are closely interrelated and the scale should be interpreted as a single total score.
