My bad knee continues to be a problem. It's been five weeks since my fall and I've been getting treatment every week. The swelling has now gone down to leave a large lump on the top of my tibia. The lump is egg shaped and gives a little if you press it. I'm told this is a haematoma, a blood blister that formed on top of the bone when it was bruised in my fall. The lump is no longer very painful and I'm told it will go away in time.
The knee joint itself is the most painful: it still feels weak and I get stabbing pains with certain movements, especially when walking. I've been wearing a support bandage a lot of the time. The physiotherapist now believes that I have torn a cartilage. I'm booked to have a scan on my knee which will tell for sure.
You have two pieces of cartilage in each knee. They are crescent shaped and look a little like the segments of an orange, thicker on the outside of the knee and thinner on the inside. The cartilages fit between your tibia and femur, working as shock absorbers. A sudden impact on your knee, particularly with a twisting movement, can damage them.
The outer edge of the cartilage has a blood supply and thus can repair a small tear. So I've been doing plenty of hot compresses on my knee to help stimulate this. The inner surface of the cartilage doesn't repair. It's possible to have surgery to repair large tears of the cartilage and for damaged pieces to be removed. But, especially given my recent experience, I don't want to go down that road.
As driving is a little painful, I'm leading a fairly enclosed life. At home with my injury I surf the internet and watch plenty of TV, which has driven me to fix the drip on the kitchen tap and other minor tasks around the house that I had been putting off. I don't seem to be in the mood for writing very often. It's pretty frustrating, this is the longest interruption to the active life that I've been enjoying over the past three years. And of course I'm very worried about what the scan will show.
