Roentgen anatomy of the posterior horn of the lateral meniscus.
The roentgen anatomy of the posterior horn of the lateral meniscus of the knee is presented with particular attention to the relationships between the popliteus tendon, joint capsule and meniscus. The popliteus tendon creates a tunnel as it passes obliquely through the posterior half of the meniscus creating two walls (medial and lateral) and a roof (superior attachment) and a floor (inferior attachment). The boundaries are readily visible on the double-contrast knee arthrogram. Familiarity with these relationships aids in the diagnosis of meniscal injuries.
