The lateral meniscus attaches to which structures?

The lateral meniscus attaches to which structures?

• A. MCL, semimembranosus
• B. Patellar tendon
• C. Quads, popliteus, and semimembranosus
• D. LCL, quadriceps

Answer: (C)

The lateral meniscus has attachments that connect it to several nearby structures to allow smooth movement with knee motion. It is closely linked with the popliteus tendon, which helps guide and stabilize the lateral meniscus as the knee bends, preventing pinching. There are also connections formed by fibers from the semimembranosus region (the oblique popliteal area) that reinforce the posterior aspect of the joint and tie into the lateral meniscus. In addition, the lateral side of the knee transmits forces from the quadriceps through the joint capsule and surrounding retinacular tissue, so the lateral meniscus is indirectly connected to the quadriceps mechanism as well. That combination—connections to the quadriceps mechanism, the popliteus, and the semimembranosus–derived structures—explains why the lateral meniscus is attached to those three areas. The other options don’t reflect these multiple, specific soft-tissue attachments.
