Why spend the money on a exercise pool?

In the U.S., the average hospital charge for a total knee replacement (TKR) is $49,500. A partial knee replacement (PKR) typically costs about ten to twenty percent less than a TKR. Aquatic exercise can reduce pain, help maintain muscle strength in affected joints and reduce joint stiffness. The added buoyancy of a swim machine makes it easier to exercise, and the privacy of your own backyard makes it convenient. The cost of a swim spa ranges from $14,000 to $25,000.
