I felt a sliight pop in my knee and feel into pain i can walk on it and it dosent realy hurt its around the front of my leg i dont know if this is minor or major i dont remember if it was during or after the jump but during that time pain isued?

Likely not serious : Pop can be heard in knee just as stretch of ligaments - not necessarily injury or problem . If able to walk without pain , no swelling , no bruise o no other discomfort. Most likely nothing happened . With jump muscle can rupture or tendon but usually require more force for such an injury . Ice is good for minor discomfort. If any doubt seek doctor for exam. Keep flexibility and healthy weight .
