What Does The Following MRI Report Indicate?
Question: About a week 1/2 ago I was squatting close to the ground and when I stood up I felt a tear in my knee and my knee locked. Eventually I was able to move it. I have had intermittent pain,limited movement and swelling since. I just got my MRI report and it says:
There is a large osteochondral defect seen over the mid to posterior aspect of the medial femoral condyle, mid to laterally positioned. The defect measures 3cm in AP dimension x 2 cm in transverse dimension x 1 cm in depth. Within the defect, there is a fragments body that is hypointense on T1 and T2-weighted imaging, appearing fractured. This body in total measures 2cm in length x 5mm in height. Fluid fills the defect and surrounds this body, which is concerning for a loose fragment. There suprapatellar effusion. The larger focus measures 11mm in diameter and the smaller focus measures 8mm in diameter. The marrow signal adjacent to the defect is normal. There is a moderate effusion.
The menisci are normal. The anterior and posterior cruciate ligaments are normal. The extensor mechanism and collateral limits are normal. The popliteus tendon is normal.
There is mild condromalacia involving the medial patellar facet. The trochlear cartilage is normal. Lateral compartment articular cartilage is normal.
1.What does this mean?
2.What causes this? I didn't have any traumatic injury. Why does it feel like its tearing apart at times?
3. What would they do to treat it?

Brief Answer:
It means a tiny piece of the tip of your joint, commonly from minor traumatic injuries or underlying disease and treated perfectly with endoscopic interventions.
Detailed Answer:
Hi,
I have gone through your question and understand your concerns,
I hope your knee feels better soon.
The MRI means that you have a bony eminence within your knee joint, most probably from your previous squatting. It happens when joints are vigorously moved in an abnormal movement or due to the hyper extension of your ligaments . may be it had previous minor injuries or arthritis that have exaggerated the osteo chondral lesion to be torn off your bone.
The cartilage that lines the end of the bone is torn by hyper extended ligament away from its origin. Usually, in defects, more than 2 cm (cubic centimeter) will be highly suggestive for surgical endoscopic repair for proper treatment. your surgeon will undergo osteo chondral autologous transplantation from a health cartilage part of the same knee.
Nowadays endoscopic interventions are very well developed and theses procedures are highly efficient if done properly.
Wish you good health,
Any further clarifications feel free to ask.
