Knee Pain

I am a 6'3" 245lb 23 year old male, and have been experiencing knee pain for the past month or so. This happened when I was performing Verticle Jumps at a track practice. When I landed, i felt a sharp pain in the middle of my left knee. I did not feel any popping, just a very sharp pain right behidn the patella. I didn't think anything of it that day, and it never bruised or swelled. I laid off the knee for the remainder of the week, but when i started lifting the next week, anything that put stress on the knee hurt. Squats, Legpress, Deadlifts, they all hurt right at the middle of the knee behind the patella. It also hurts when I try to jog and occasionally go down stairs. I saw an athletic trainer and he believes that it may be a bruised femure. I was wondering if anyone else had an opinion on this, and if they agree with the bruised femure, how long do you think this will last/are there any treatments I can do to speed the recovery process/can i do any form of cardio?

Thanks

Hi there. This seems to be sports mediated injury most likely a ligament tear or damage like if  it is a medial or lateral meniscal tear or injury. this could be anterior cruciate ligament or the ACL tear. Consult an orthopaedician for evaluation and you might require an arthroscopic exploration of the knee joint and ACL reconstruction under regional anesthesia. Xray of the leg including knee joint is of course required to rule out bony fracture. You can take over the counter NSAIDs, apply hot fomentation etc for supportive therapy. Hope this helps. Take care.

Don't agree with the "bruised femur" diagnosis/guess because the problem is related to the knee.  Your femur is your thigh bone.  Sounds like a tendon or ligament issue with the knee.  I would recommend NOT doing any jogging, running, etc. until you are seen by a physician and I would recommend doing that ASAP.  

Have you used ice and/or heat?  Tried any anti-inflammatories, i.e. Motrin.  

How long the knee will take to recover I am not sure about that.  It probably won't be less than month.
