The surgery will be on the shorter leg. I lived with a shorter leg for 70 years. We just discovered this fact 3 years ago. I suppose it explains the huge issues I had with back pain all my life. I tried ant-inflammatory pills, then I went to natural products glucosamine, collagen etc... then I added exercises, physiotherapy , essentrics. My shorter leg is now also crooked due to the degenerative arthritis ....I'm a mess...I only saw my doctor once for 10 minutes and I have been on the waiting list for the surgery for 1 year (Canada health system) ...I will try to insist in seeing him again before the surgery to answer my questions. Does the surgery fix a crooked leg?
