Description of intervention(s) / exposure
Completion of questionnaire documenting further knee injuries, return to sport, and patient reported outcomes in a series of athletes at 3-12 years after ACL reconstruction. Results will be grouped according to sport of primary injury to determine the incidence of reinjury and return to sport across sporting populations. This is estimated to take 5-7 minutes to complete

Statistical methods / analysis
Statistical analysis will be performed using SPSS software (IBM Corp). Statistical significance will be set at P< .05. The probability of failure will be estimated as a function of time using the Kaplan-Meier survival method. Survival tables at 1, 2, 5, 10 years will be collated. Comparisons of survival curves will be made with the univariate Cox proportional hazards model. Factors that are significant (p<.05) or nearly significant (p< .10) on univariate analysis will be entered into multivariate Cox regression analysis. Factors are then eliminated one at a time in a stepwise fashion until only the independent significant factors remain.

Summary
Brief summary
Potential participants will be identified from an existing database of knee surgery with ethical approval. If the sport of injury is undocumented then the participants medical record will be reviewed, which is within the parameters of the approved database. Participants will be contacted via email where possible and invited to complete the questionnaire online, using RedCap questionnaire which is hosted on a secure medical server at St Vincent’s Hospital. The questionnaire should take less than 5 minutes to complete. Participants who are unable or unwilling to complete the questionnaire online will be invited to complete a paper copy of the questionnaire, which can be posted to them and include a reply paid envelope.

The questionnaire will consist of the ACL RSI scale, which is a disease specific, reliable and validated questionnaire for ACL injuries. Participants will also be asked if they have made a return to sport, whether any of their direct family members have had ACL injuries, and if they have sustained any further injuries to their knees. Results will be grouped according to sport of primary injury to determine the incidence of reinjury and return to sport across sporting populations.
