The approach employed in the meta-analysis of QT and PL autografts for ACL repair is summed up in this graphic. It describes the procedures for data extraction, quality evaluation, statistical analysis, inclusion/exclusion criteria, and literature search approach. Biomechanical performance, functional recovery, clinical success, and donor-site morbidity are among the important outcomes that are examined.

Stage	Details
literature Search	PubMed, Google Scholar (until Feb 2025)
Keywords	"QT autograft," "PL autograft," "ACL reconstruction," " biomechanical outcomes," "functional outcomes," etc.
Inclusion Criteria	Studies comparing QT/PL with hamstring or patellar tendon; human case-control, cohort, or RCTs.
Exclusion Criteria	Non-autograft, animal/in vitro studies, reviews without full-text access.
Data Extraction	Two independent reviewers; third for conflicts.
Quality Assessment	Newcastle-Ottawa Scale (observational); Cochrane risk-of-bias tool 9RCTs).
Statistical Analysis	Random-effects model, SMD (continuous), OR (dichotomous), I² > 50% = significant heterogeneity, P < 0.05.
Key Outcomes	Biomechanical (tensile strength, load-to-failure, graft diameter), functional (ROM, strength, stability), clinical (return-to-sport, graft failure, re-injury), donor-site morbidity.
