Optimal Timing of Anterior Cruciate Ligament Reconstruction: A Narrative Review of the Intra-articular Consequences of Prolonged Injury-to-Surgery Intervals.

This study aims to determine how the timing of anterior cruciate ligament (ACL) reconstruction affects the prevalence and severity of associated meniscal and chondral injuries. This literature review critically synthesizes existing research on the timing of ACL reconstruction and the impact of prolonged injury-to-surgery intervals on intra-articular knee lesions and functional outcomes. It examines evidence concerning the correlation between surgical timing and intra-articular knee injuries that supports or refutes the hypothesis that longer intervals from injury to surgery worsen intra-articular pathology. This correlation is essential to guide surgical decision-making, optimize treatment timelines, and avoid long-term joint degeneration. Ultimately, delays beyond six months significantly increase the likelihood of irreparable meniscal tears and poorer functional outcomes.
