Hello doctor,

I underwent quadriceps tendon repair surgery in August of this year. After that, as per the MRI finding, I developed patchy marrow edema in the patella and lateral femoral condyle. However, MRI does not mention articular cartilage damage, chondromalacia patella, or arthritis in the reports. I have been running for the last 15 years till February this year. Please inform me if there are any indications of articular cartilage damage, chondromalacia patella, or arthritis in the MRI images attached herewith. Also, please inform me of any other material finding in the MRI, throwing light upon the possible reasons for the marrow edema or any other material finding noticed by you in the images. Thanks.



Welcome to

I read your query and can understand your concern.

So I went through your MRI (magnetic resonance imaging) images (attachment removed to protect the patient's identity) and made additional observations.

1. There is evidence of thinning and irregularity of the patellar articular cartilage (evident on sagittal cuts) along with abnormal PDFS (proton density fat saturated) signal within this cartilage (evident on axial cuts, see the second set of images, fourth image from the left) suggestive of chondromalacia patellae.

2. Chondromalacia patellae can result in patella alta or a high-riding patella, for which I need to make a few measurements requiring images in a DICOM (digital imaging and communications in medicine) format. However, measurements are impossible since you have uploaded scanned images of films provided by the laboratory. Also, I would like to know if these are the only images provided by the laboratory?

3. There is no obvious evidence of arthritic changes in the images provided.

Please note that edematous changes in bones and myofascial tissues can be post-operative or post-traumatic. Changes can last anywhere from six to eight months up to a year.

Hope this helps.

Thanks and take care.

Hello doctor,

Thanks for the reply.

I also have a CD, but I am unsure if the CD image (ISO file) can be uploaded. However, I can come for an in-person consultation at your clinic address. Please let me know if it is advisable.

You can try uploading the CD (compact disk). It might work.

Hope this helps.
