Description of intervention(s) / exposure
This study will employ a retrospective, longitudinal design using secondary data. The data will be collected from the medical records of patients who underwent anterior cruciate ligament reconstruction (ACLR) at the Hospital Canselor Tuanku Muhriz (HCTM) over four years from January 2020 to December 2023. The study population will include all adult patients (aged 18–45 years) who underwent ACLR at the hospital between January 2020 and December 2023 and have documented preoperative and postoperative assessments of knee muscle strength and physical function at the Orthopaedic ward/clinic and Physiotherapy Unit of HCTM.

The primary outcomes of this study are 1) the percentage of quadriceps and hamstring strength between operated and non-operated knees and 2) the functional performance (single-leg hop test).

The secondary and exploratory outcomes measure patient-reported outcomes on symptoms, function, and sports activity based on the International Knee Documentation Committee (IKDC) questionnaire score, as well as the level of patient adherence to rehabilitation sessions.

All the outcome measures will be obtained from the patient's medical record, as evaluated by the physiotherapist and physician in the HCTM between preoperative, 3-month, and 6-month postoperative ACLR.

2) Patients with complete and accessible medical records, including preoperative, intraoperative, and postoperative data.
3) Patients who have undergone standardized assessments of knee muscle strength, physical function, or related evaluations at specified intervals post-surgery (e.g., pre-operatively, 3 and 6 months).
Minimum age
18 Years
Maximum age
45 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria

Statistical methods / analysis
Descriptive statistics will be employed to concisely summarise the characteristics of the participants and the prevalence of impairments in knee muscle and physical function. The analysis will use Chi-square tests to estimate the frequency of the study population's demographic characteristics and categorical variables (type of graft, concomitant bone/chondral lesion and level of adherence), as well as linear regression analysis to identify influence factors and predictors of ACLR outcome. Furthermore, the Pearson correlation test will be employed for continuous variables and normally distributed data, or the Spearman correlation for ordinal or non-normally distributed data. The Bonferroni post-hoc test will be performed to identify differences in the relevant analysis. The significance level is set at P <0.05. Additionally, the odds ratio (OR), 95% confidence interval (CI), or Z-score will be included.
