I experience a non impact injury on September 11th, I was cutting about to make a tackle and my knee gave out. I could walk, but with a limp and moderate pain. I went to the doctor 3 days later, and he thought my ligaments felt good and due to little swelling and tenderness that I tore my meniscus. I got my mri results back today and all the ligaments look fine, but I had a large bone bruise on the medial side of my knee.'

I have pain on both sides of my knee cap when walking up stairs and pain in the back of my knee. Both my medial and lateral side hurt, and is tender to the touch. He reaper formed all my ligaments tests as my knee has been feeling unstable recently. Everything felt good again, this along with a clean mri he thinks its only a no bruise. Could a bone bruise cause all this or is it a meniscus tear?

Also in class today I was being my knee and when it touches my butt it felt like my shin bone or ligament slides forward, It does this everytime. Is this normal I'm only 15 and still growing?

Bone bruises can be nasty, nothing 'just' about them - I had a big one in my femoral condyle (along with a meniscus tear and damage to the cartilage too) - can take 3-6 months or longer to heal properly if a bad one

Ice, rest, elevation, minimal impact best

Good luck

I'm not a doctor - I cannot tell you what the issue is from a couple of lines on the Internet (then nor could a doctor) - you said the MRI showed a bone bruise - I was responding to your "if it is just a bone bruise"  They can be nasty, hurt a lot (especially if under a weight bearing surface) and can take longer than 3-4 weeks to heal.  If you run in 3 -4 weeks it may well hurt

The doctor thought it is a meniscus tear, MRI showed not, but MRIs are notoriously poor at showing meniscus tears - follow the doctor's advice, and the physio and see how you go.  Meniscus tears often come with pain, swelling, locking of the knee and potentially buckling.  They can heal alone depending on where they are - if they are in the bit of the meniscus where there is blood supply.

At 15, you need to take the advice of your doctor, physio, sports teacher, parents.

Good luck

My first MRI showed a "possible!" Meniscus tear. I took my chances and tried rehabbing and going back into sport.

1 year on the symptoms persisted and the second MRI showed a definitive and progressed meniscus tear.

I then had surgery and because I waited for so long more meniscus needed to be taken out.

My suggestion is that if after 3 months or so, issues persist - get a second scan / opinion and probably surgery - almost 2 years on from my partial menisectomy, I have no meniscus issues / symptoms!

Also sorry about my horrendous spelling in my first post I'm on my iPhone.
