Observations, with questions for you wise people out there. A short time ago, two people close to me have had knee replacement surgery. Now both are bothered more by back, or sciatic pain, than by knee pain. I am wondering if this is a result of waiting too long to have the knee replacement and other areas of the body are compromised by compensating for the bad knee? I have been told in many cases, the strategy is to delay the replacement until an age when the artificial joint will last for the rest of the recipients life. Trying to be proactive on this, as the last year has brought some various knee pains my way during training and touring.
