(English) Episode 240-The Hidden Kaplan Fibers Stabilizing Your Knee

This comprehensive review examines Kaplan fibers (KFs), which are critical anatomical structures within the iliotibial band that maintain rotational stability in the knee. Researchers highlight how these fibers work alongside the anterior cruciate ligament (ACL) and other ligaments to prevent excessive internal rotation. While MRI is an effective tool for identifying these fibers, the literature notes a high frequency of injuries that may naturally heal over time. To address persistent instability after ACL tears, various surgical techniques like lateral extra-articular tenodesis (LET) are utilized to replicate the function of these fibers. Ultimately, the review calls for more standardized diagnostic criteria and further clinical research to optimize long-term patient recovery and joint health.(Poursalehian M, Hajiaghajani S, Ayati Firoozabadi M, Dehghani Ashkezari D, Mortazavi SMJ.
