摘要

A ramp lesion is a lesion of the meniscotibial and meniscocapsular ligaments in the posterior part of the medial meniscus. This type of meniscus lesion usually occurs in combination with a rupture of the anterior cruciate ligament (ACL). Since the meniscus ramp biomechanically supports the ACL in supporting it against anterior tibial translation as a secondary stabilizer, it is recommended to repair unstable ramp lesions in the event of a combined injury. To visualize the ramp lesion, the arthroscope must be pushed through the intercondylar fossa (transnotch view) into the posteromedial compartment. The meniscotibial and meniscocapsular ligaments can be checked with a puncture cannula, thus, allowing the ramp lesion to be diagnosed (hammock sign). A posteromedial portal is then created through which the ramp lesion can be treated. The lesion is debrided with a motor-driven synovial resector. A suture hook instrument is then inserted through the posteromedial portal to penetrate the torn meniscotibial and meniscocapsular ligaments and the base of the meniscus and a suture thread is guided through the tissue. The edges of the lesion are adapted using a sliding knot via this suture thread (e.g., fishers knot). In this way, the ramp lesion is repaired with two to three sutures. The rehabilitation protocol includes 2 weeks of partial weight bearing, range of motion 90° after 2 weeks and 120° after 6 weeks.
