By letting go of harmful desire, I got more of the physical depth that I'd wanted before, yet the shapes of the poses barely mattered now. What did matter was how good it felt to just be with what is and let go of what isn't.

So here I am, waiting for the arthroscopy that will cut away the torn meniscus of my other knee and advance me toward premature arthritis. I should have seen that beyond the end of the long jump sand pit, but I didn't. I am using this week of waiting to reflect upon my changed condition.

It's no wonder that by the time you reach age 60, chances are good you will have developed osteoarthritis of the knee, a sometimes-painful condition caused by wear and tear to the knee joint.

Meniscal tears in young athletes can either be repaired or trimmed, but determining which is best is a complex decision-making process.

Recently, a police officer underwent two surgeries including a partial knee replacement . When he walked he had severe pain and would hear a "popping noise." He also had trouble walking, even with a cane.
