My progress to date has been amazing. I am running up to 40 miles a week (albeit, slowly and taking it easy downhill), today I ran 10 miles for the first time since my op. The hills near where I live are covered in snow so I took the opportunity to run with a lovely, soft cushioning of snow! I really have to hold myself back as I still feel apprehension regarding doing too much too soon on the joint! I have a check up next week and hopefully I may be given the all clear to begin more (gradually) intense training. At 63 years' old I know it must be because of my decades of running at a high level that have enabled me to return amazingly quickly to trouble-free running! I continue with gym work including leg strengthening and have almost achieved full range of motion (about 150 mm to go until knee touches shoulder). I am still finding it difficult to improve upon this knee to shoulder distance and I do not know why! Do I need a physio to force it or is that a no no?
