Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.
Funnily my husband is having the same surgery this Tuesday . Same knee, same type of tear, same surgeon. Hope all goes well.
That same year, I also had a family member have surgery like you are describing. I know she was quite mobile almost immediately, but it still took quite a while for the swelling to go down.
It's hard to find good information about the connection between knee surgery and clots, but it seems like the immobility, healing process and the swelling might all impact the possibility of developing a clot.
Personally, I think I would want something more than just aspirin following any kind of knee surgery for at least 3 - 4 weeks, but that may be me just being paranoid now.
Most importantly, watch for symptoms. For me, it started as a strange feeling in my foot that moved to my ankle and then my calf. My big mistake was asking my surgeon about it rather than just going to a regular doctor or straight to the ER for an ultrasound. My surgeon misdiagnosed the clot and then I ended up with a PE less than a week later.
Good luck!
I would just discuss with your surgeon your clotting history, your concerns, and what is the plan to prevent post surgical clotting.
This is not the same thing as a knee surgery in terms of clotting risks, but when I had gallbladder surgery, my surgeon suggested during our pre surgical discussion staying over night as a precaution due to my clotting history. My surgery was in the a.m. and I was on lovenox that evening and also started warfarin.
Being on anticoagulants can slow down healing sometimes,so the post op anticoagulation may be different with knee surgery, but these are the types of things I'd ask. the surgeon, ie when to start lovenox, warfarin, etc.
