OUCH! Does that ever look familiar. Looks like my old brace. Was off work for three months several years ago before I retired. Had experimental surgery at the time and was the 5th. one the ortho doc did. Worked like a charm. Total range of motion back and no pain after having it for 45 years or more. Old football injury that I finished off by slipping at the edge of a small mountain stream and landing on rocks instead of in the water. Just be careful when you start back wading again. And do like me; take a wet dump instead of trying to do the fast foot shuffle and mess the knee up again. Good luck and can't wait to see some of your postings photos once again.
