If you want to get back to skiing, learn to love your physical therapy.

It took my expert knee replacement surgeon one hour to cut, saw, hammer and install each new knee. It took me a year to rehab them. I was astounded by how long it took.

I was in good physical condition before surgery, and I had the mind set that I would bounce right back. I’m strong. I’m tough. I thought that a set of new knees would be something like taking my car in for an oil change. Drive in with old oil. Drive out with new oil and keep on rolling. I was incredibly wrong. The analogy didn’t work. Healing and rehab take time

The good news is: The body is a healing machine.

The bad news is: Lots of people slack off their physical therapy exercises as soon as they can get into the car and do their grocery shopping. They lose their motivation and unfortunately they don’t get full benefit of their new knees. They probably aren’t skiers. We skiers are motivated to get back to the sport we love.

Eight months after surgery I was back on the slopes – starting on the opening day of the season. I skied 93 days that year. EEEhaw! (During the winter before knee replacement, all I could do was skid down a bunny slope.)

Friends asked: “How long did it take to get used to artificial knees?

My response: “About six turns.” My new knees worked wonderfully.

Skiing is good exercise, but it’s not focused physical therapy. Continuing the prescribed exercises was vital. Now, two years later, I still do certain exercises. I believe that maintaining artificial knees is an ongoing process.

My new knees do have some minor disadvantages. I cannot squat with my butt down to my heels. Artificial knees aren’t designed to bend that far. Therefore I sit on a low stool while weeding the garden. And swimming laps confounded me because it took more strokes to get across the pool. I think that’s because metal is heavier than bone, so my legs are lower in the water. I had to find a new balance point for swimming.

The bottom line is this: When the surgeon is done, your work is just beginning. Do your rehab exercises with gusto – and I’ll see you on the slopes.
