MRI Results
« on: September 14, 2018, 10:53:40 PM »
Background:  I had ACL reconstruction in 2012.  I also had my knee scoped two years following that.  I had an MRI a couple of weeks ago and I received my results, but I don't know what they mean.  Your help in deciphering this report would be wonderful.

1. Postsurgical change from anterior cruciate ligament reconstruction. Intact graft.

2. Moderate osteoarthritis, with regional high-grade chondromalacia as described above.

3. Chronic meniscal degeneration, without a discrete tear.

4. Minimal Baker's cyst, and very minimal joint effusion.

5. Edema-like signal in the popliteus muscle, possibly secondary process from a subacute Baker's cyst rupture. Differential includes grade 1 muscle strain.


Partially limited due to patient body habitus and motion artifact. Minimal Baker's cyst and very minimal joint effusion.

MEDIAL COMPARTMENT: Chronic degeneration of the medial meniscus, including minimal free edge fraying of the body. No discrete meniscal tear. Regional high-grade cartilage thinning in the central to posterior weightbearing thirds of the medial femoral condyle, with possible small area of full-thickness cartilage loss. Low-grade colitis thinning in the anterior aspect of the femoral condyle with moderate to marked osteophytes. Low-grade medial tibial plateau cartilage thinning with minimal osteophytes. Medial collateral ligament intact.

LATERAL COMPARTMENT: Chronic degeneration of the lateral meniscus, including free edge fraying of the body. Minimal subcortical cystic change at the anterior root attachment at the proximal tibia. Marked high-grade cartilage thinning throughout the lateral femoral condyle weightbearing portion, with superimposed surface fibrillation. Large osteophytes. Low to intermediate grade cartilage thinning in the tibial plateau, with small osteophytes. Lateral collateral ligament intact.

POSTEROLATERAL CORNER: Moderate popliteus tendinosis. Minimal proximal tibiofibular osteophytes.

EXTENSOR COMPARTMENT: No patella alta. Normal trochlear groove. No lateral patellar tilt or translation. Medial and lateral patellar retinacula are intact. Quadriceps and patellar tendons are intact with moderate to marked tendinosis. No thickened plica. Low to intermediate grade cartilage blistering and the medial patellar facet. Intermediate grade thinning and blistering in the central trochlear sulcus extending into the medial facet. Postsurgical scarring in Hoffa's fat pad.

INTERCONDYLAR COMPARTMENT: Postsurgical change from anterior cruciate ligament reconstruction. The graft is intact and there is no evidence of fluid along the tibial or femoral tunnels. The posterior cruciate ligament is intact.

No fracture or osteonecrosis. Muscle bulk normal. Visualized nerves and vessels are normal. Edema-like signal throughout the popliteus muscle, possibly due to Baker's cyst subacute rupture versus muscle strain.

Essentially you've got arthrtis in the main compartments of your knee, both medial (inner) and lateral (outer) affecting the weight bearing areas of thigh and shin bones. Your cartilage is thinning or has full thickness damage and the bone underneath is also damaged as a result. You also have bone spurs due to the cartilage damage.
Also to the patella and the groove where the patella sits.
Your meniscii are in quite a poor degenerate state, although no specific tears.
You've also got long term inflammation to the tendons

Your MRI reads a bit like mine, with the addition of prior ACL surgery (which is ok it says)

What symptoms do you have? How active are you? Are your knees well aligned? How old are you? Why did you have the scoped in 2014? Was it due to the fat pad? Was it trimmed? Although scarring can also result due to arthritis.

You might find the anatomy, arthritis and meniscus primers here useful
What has your knee specialist said in terms of diagnosis and prognosis?

Thanks for help in deciphering my results.  I just received them through the automated service and haven't been back to the doctor yet to hear what he has to say.  I just wanted to know what was going on before I went for my follow up appointment.

I had my knee scoped after my reconstruction because I had cartilage that had torn and had come off.

My current symptoms are pain (mostly while sitting and going down stairs), swelling, grinding (crunching), and my knee sometimes locks.  I am pretty active.  I religiously take my meloxicam and pain meds (when needed).  I work out multiple times a week.  I know that eventually this knee will have to get replaced, but I am only 41 years old and so I am wondering what my other options are?  My situation is worker's comp., so I sometimes feel like I am the only person with my best interests in mind.  Thanks again for your help
