What severe injuries are possible from hitting trochlear groove in knee into corner on a table? It was with extreme force with bent knee.

What severe injuries are possible from hitting trochlear groove in knee into corner on a table? It was with extreme force with bent knee.

Contusion mainly: Despite the attention-getting pain, unless you have very thin/weak bones, it is unlikely to result in a break (but not impossible); and more likely to be a bruise (/contusion) of the ligament/tendon passing through there--which can take a few weeks to heal. Tear / worse damage also possible. If rest-ice-compression-elevation & Ibuprofen do not help with pain after 3-5 days, should see orthopedist. ...Read more

What does slight lateral positioning of the patella and shallow trochlear groove with min. anterior lateral femoral condyle ridge reactive change mean?

What does slight lateral positioning of the patella and shallow trochlear groove with min. anterior lateral femoral condyle ridge reactive change mean?

Common MRI : It means that your kneecap sits slightly off to the side on the end of the thigh bone( trochlea) @ 90degrees of bend. ( flexion), and your 'groove' ( trochlea) is slightly shallow on your femur. Very common radiologic ' diagnosis' , seen most commonly in patients w/ 'mild' patellar instability or ' kneecap' pain. See your ORS for significance . Best of Luck! ...Read more

My MRI results say chondromalacia involving the medial femoral condyle as well as the central trochlear groove also joint effusion what does this mean?

My MRI results say chondromalacia involving the medial femoral condyle as well as the central trochlear groove also joint effusion what does this mean?

Cartilage injury: Chondromalacia is damage to the cartilage surfaces of joints. In the knee it's similar to the wearing away of tire treads. This can cause inflammation which can produce increased fluid in the knee (effusion). If you have minimal pain and no locking, strengthening your thigh and leg muscles is recommended. Icing and anti inflammatories and pt can be helpful. Arthroscopy is recommended with locking. ...Read more

I have grade 2 chondromalacia patella and grade 3 of the trochlear groove, confirmed via arthroscopy. Does this qualify me for knee replacement?

I have grade 2 chondromalacia patella and grade 3 of the trochlear groove, confirmed via arthroscopy.  Does this qualify me for knee replacement?

No: Surgical replacement of the knee is the last resort. Regular exercise to decrease and maintain weight and to improve joint strength : swimming, water aerobics/ walking; bike riding. Use water weights for weight training and muscle building. Talk with your Orthopedic doctor about injections ...Read more

Left knee MRI shows I have trochlear groove arthritis. What aerobic exercises can I do? Cycling? Running? Stair climber?

Left knee MRI shows I have trochlear groove arthritis. What aerobic exercises can I do? Cycling? Running? Stair climber?

Non impact ideally: Your patellofemoral joint (where the knee cap meets the trochlear groove on the femur) sees 3-6 times your body weight and this is even more with running and other high impact exercises. Ideally you should stick with non impact activities like cycling, swimming and using the elliptical. The stair climber will likely be very tough because the amount of stress it puts on the pf joint is very high. ...Read more

Please let me know if there is an operation available for trochlear 4th cranial brain nerve damage?

Depends: if the nerve is currently entrapped - yes. If the damage was done previously, but the original injury was repaired - probably not. If the nerve was transected it's unlikely to recover, if it was partially damaged it may recover at 1 mm/day. ...Read more
