I had my second ACL surgery done on my left knee because my graph was rejected and I developed osteolisis when my screw was rejected, resulting in big holes in my bone. I have had persistent pain and popping in my left knee, so my physician ordered an MRI and I cannot interpret the results for myself:

1. ACL reconstruction is present with tibial and femoral intereference screws producing a large amount of susceptibility artifact along with intra-articular metallic susceptibility artifact from prior arthroscopy. The susceptibilty artifact precludes adequate assessment of the ACL graft for signal absnormality and integrity. However, there is no abnormal translation of the tibia suggestion that the ACL reconstruction graft is intact.

2. Type II degenerative signal is present at the posterior horns of the menisci.

The lateral collateral ligament complex is intact. However, there is minimal thickening and intermediate signal at the distal popliteal tendon as it insterts in the lateral femoral condyle.

3.The lateral patellar retinaculum is abnormal with thickening and intermediate signal seen in the distribution of its superior fibers.

I would appreciate any help I can get. Thank you so much!!

Hello, Poolchick,

Oh gosh, I just noticed you had posted several days ago and not gotten any response.

Here's my interpretation of your MRI--

1. Screws from your prior surgeries are interfering with the MRI and making it difficult to determine the state of the ACL graft. The fact that the tibia is in a normal position suggests that the graft is in tact. (Note-- the tibia can shift when one has a damaged or weak ACL)

2. This indicates that there are changes to the posterior horns of the meniscii that are degenerative in nature rather than related to an injury. The posterior horn is the part of the meniscus that is at the back of the knee.

The thickening of the distal popliteal tendon probably indicates that it was injured at some point, maybe a sprain or partial tear. This may or may not be related to your ACL tear.

3. The thickening of the lateral retinaculum is an indication that an injury has occurred at some time.

Sorry if that isn't much help.

You may want to try posting down in the cruciate ligament section of the board. There a very active group of people who post down there. Many of us tend to read and post only in the section that pertains to our knee issue, so you may not have gotten many responses here for that reason.

Best of luck to you.
