After recovering from rotator cuff surgery in January, I now discover that my right knee has a torn meniscus.
From Arthroscopy.com: "Medically speaking, the 'cartilage' is actually known as the meniscus. The meniscus is a C-shaped piece of fibrocartilage which is located at the peripheral aspect of the joint. The majority of the meniscus has no blood supply. For that reason, when damaged, the meniscus is unable to undergo the normal healing process that occurs in most of the rest of the body. In addition, with age, the meniscus begins to deteriorate, often developing degenerative tears. Typically, when the meniscus is damaged, the torn piece begins to move in an abnormal fashion inside the joint.
Because the space between the bones of the joint is very small, as the abnormally mobile piece of meniscal tissue (meniscal fragment) moves, it may become caught between the bones of the joint (femur and tibia). When this happens, the knee becomes painful, swollen, and difficult to move."
That explains why I've been experiencing pain in my knee upon putting any weight on it, such as when climbing stairs. The good news is that this surgery is done arthoscopically and is very minor as surgeries go. After 48 hours on crutches, I should be able to return to my normal activities.
It's a major relief to finally find out what's wrong and that it is so simple to repair it.
My surgery is set for Thursday, June 5, after which I'll stay home from work until the following Monday, when I should be okay to return to work.
And then sometime later in the summer I should be able to mow my own lawn and eventually return to Jazzercise.
