This is a normal prominence due to the underlying head/ styloid process of the fibula and the lateral tibial condyle (bones in the lower leg); which may be better defined on some individuals. This should not be anything to worry about and you can continue your activities as normal.
Hope this helps.
Thanks for answering Doctor! The only thing I am worried about is that my other knee does not have this bump and that I am almost certain this bump was not there before. If it was there, it was not as prominent.
Well, if there are no other symptoms present like pain or discomfort in moving the knee and the swelling is hard and non-mobile; I would suggest not bothering about it. The two bony points may not be equally prominent on either knee and are best appreciated by folding the knee back and slightly outward. If you still feel a major difference between the two knees, you might consider an evaluation by a primary care physician initially probably with an x-ray to see if that shows anything abnormal, like a bony outgrowth and depending on the situation you may consider seeing an orthopedician or leave it as such.
Hope this is helpful.
I looked over my knee again and it appears as the prominence you are talking about is actually a little in front and right below this bump. Folding the knee and moving it outwards revealed what you are talking about... and I do have those bone protrusions on both knees, both somewhat similar. ... Now this bump is very close to the protrusion you are talking about. After feeling it some more I realize now that it is actually somewhat softer than bone. Just a little bit. I almost want to say it's a ligament. Could it be a inflamed ligament or tendon? Or something like a baker's cyst, fluid filled cyst? I am also fairly certain that this appeared very recently. I noticed it 2 days ago while doing some leg exercises at the gym, and since I do them every few days I would have noticed it right away.
Thanks again for your help!!
Tony did you ever get an answer to your question about the ligament thing? Did you bump ever go away or what ever happened to your situation?
I am experianceing the same thing. I know my knees looked the same while I was exercising yesterday. I did a good lower body work out yesterday and things were fine. When I showered this morning I had a noticable bump under my knee sticking out much further than my other knee. Nothing hurts and I feel just fine but the bump is hard as a rock.
So what did you end up doing about yours if anything?
I did a Park run a week ago on the saturday and noticed a very slight discomfort below my left knee later on in the day. Went dancing sat night no biother and for a long run in local hills on sunday again no bother just a slight awareness of occassional discomfort. Went to the gym mon, tues wed to give avoid impact from running. On wed pm noticed a firm lump acrooan are of about1 inch just below the knee. This enlarged over night such that it protuded about 1/2 inch. No pain; not tender and felt like bone. Activity no bother unless I lunge or put sudden body wt pressure when again discomfort. I suspect I've caused some minor tssue damage and the swelling is fluid/blood but no bruisng as yet, Puzzled that it took 4 days before the lump appeared. Saw a nurse (couldn't get to see a doctor). Who wasn't particularly concerned but said to see a doctor next week if it persisted. I'm planning tomorrow sunday.I'm hopinhg it will just dissipate if I take it steady.
Hi, I played a dodgeball game two weeks ago which included fast moving and getting down on hard wood floor. After the game finished my knee hurt and was red. Two days later bruising started happening but no pain unless touched in the area. Recently I have noticed a hard bump almost bone feeling on the inside of my left leg right under the knee cap. Could you please tell me what this could be.
