Had ACL Reconstruction. MRI Showed Distal Femur And Proximal Tibia With Baker's Cyst. Suggestion?

EXAM: Magnetic resonance imaging right knee without contrast
INDICATION: Pain. ACL reconstruction 7 years ago.
COMPARISON: MRI from 1/30/2007.
TECHNIQUE: Routine sequences were performed through the knee without
intravenous contrast.
FINDINGS: The patient is status post ACL repair. The graft appears intact. The
hardware in the distal femur and proximal tibia appears to have been removed
since the prior study. Small cysts are seen in the bone tracts, more prominent
in the tibia than femur. Signal from the bone marrow is otherwise within normal
limits. Mild chondromalacia in the medial joint compartment has progressed when
compared with the previous study. Moderate chondromalacia in the patellofemoral
joint has progressed when compared with the prior study. Tricompartmental
osteoarthritis has progressed. A loculated Baker's cyst is present measuring 2.4
cm in transverse dimension, 2.3 cm in AP dimension, and 7.1 cm in craniocaudal
dimension. This has mildly increased in size since the prior study. The medial
meniscus has a stable, mild degeneration of the posterior horn without evidence
for tear. The anterior horn is unremarkable. The lateral meniscus has mild,
stable degeneration the posterior horn. The anterior horn is unremarkable. The
posterior cruciate ligament, extensor mechanism, medial collateral ligament,
iliotibial band, fibular collateral ligament, and biceps femoris tendon appear
intact.
IMPRESSION:
1. ACL graft remains intact. The hardware appears to been removed.
2. Progression of moderate chondromalacia in the patellofemoral joint, mild
chondromalacia in the medial joint compartment, and tricompartmental
osteoarthritis.
3. Baker's cyst, mildly increased in size.
Thanks for posting your query.
The findings of MRI scan are suggestive of degenerative changes in the knee joint which are mainly age related changes. This is causing the knee pain that you are having. The mild increase in the size of Baker's cyst is not worrisome.
The ACL graft is intact. The hardware is the material with which graft is fixed with the bones- it can be screws, buttons, pins, or similar devices. Some of those devices are made out of materials that reabsorb or dissolve with time and are replaced with bone by the body. This is why it has been mentioned that the hardware appears to be removed.
Stretching and strengthening the quadriceps and hamstring muscle groups is critical for proper treatment of chondromalacia patellae. Quad sets are done by contraction the thigh muscles while the legs are straight and holding the contraction for a count of 10. Sets of 10 contractions are done between 15-20 times per day.You can do the required exercises under the care of an expert physiotherapist.
Heat application and use of knee brace is advised for proper knee support at the time of exercise.
Avoid such activities as squatting, kneeling, heavy lifting, climbing, etc.
Adding glucosamine sulfate as supplement after consulting your orthopedician may help in relieving your symptoms.
I hope this answers your query.
