I had an opening wedge HTO on the medial side of my left knee in January of 2011. It was painful for the first six weeks, but the swelling and pain eventually subsided and I could start using the elliptical. For all of 2011, I biked, used the elliptical and did strengthening exercises just about every day. I did not attempt to run because I still had the clamp in. The clamp came out in February of 2012. I started to run, but it hurt. So I gave it another few months. I started back up around April. I could only go a few miles at a very slow pace. I was still using the elliptical and strengthening every day. It wasn’t until September of 2012 that I could run pain free. In October of that year, I did my first ½ marathon since my surgery. After that, I was back to normal running. In October of 2013 I did my first post operation marathon. I ran a 3:29. It was not what I was doing before, but I was happy. I continued to run well and completed 12 marathons between 3:29 and 3:42 (including one Boston Marathon). Finally in July of 2020, my knee started hurting. Went back to my doctor and got an MRI. He said the HTO was about at the end of its life and said it’s time for a partial. I always knew this would happen, but I was still disappointed. My PKR surgery is scheduled for January 29th of 2021. I’m hoping to continue to run marathons.
