>> Hello,
>> I was hoping for a little help on this case from last week. This is a 62 year old male with recurrent knee effusions and pain over the past year. Immediately anterior to the anterior horn and root of medial meniscus, is an oval shaped structure that isn’t truly cystic. This is immediately anterior to the anterior intermeniscal ligament insertion site. When evaluating the meniscus, the intermeniscal ligament insertion seems to extend farther medially than I am used to. My first question is can you get a “wrisberg rip” type injury associated with the anterior intermeniscal ligament?

It’s a ganglion of the transverse meniscus ligament, leave alone
This ligament is covered by synovium and any syn inj can lead to a ganglion like ACL mucoid/ganglion
ps case from today (3 images)- similar on lateral aspect and couple of older cases with larger cysts

Hello,

I appreciate your thoughts and advice in advance.
