Now if you are truly bleeding inside the knee joint, that is NOT a normal phenomenon. The first thing to do would be to determine as to why you are bleeding inside the knee joint, if there is no history of trauma then it is likely the bleeding is due to a clotting disorder. this could due to a problem in the platelets or even with the clotting cascade. The first step here would be to get a CBC and PT/APTT/INR test done which would give us more information about this process. Secondly an ultrasound is also necessary here as well.
Now i hope you have had these things done and if not, these should be done ASAP, a MRI would also be necessary here.Now blood inside the joint is a serious thing, and in most cases the initial treatment is conservative. This means that you would have to be on bed rest for the next few weeks, splinting may be necessary as well as avoiding things which could worsen the bleeding such as OTC motrin or aleve as well as drugs like aspirin. In addition you should keep the affected leg as elevated as possible, avoid trauma to the knee and also avoid putting weight on it. But apart from these simple things nothing else can be done. The best solution would be to go for an arthroscopy to see where you are actually bleeding from inside the joint (if the blood tests are normal), this also has the benefit of draining the joint of the excess blood which can get infected if left inside.
I would suggest that your proceed with the bed rest but do get the MRI and arthroscopy done ASAP.
Do you have any more questions?
