Update
I’m now 9 months post op (TNR), and I’m making progress. I recently cycled around the island of Gotland in Sweden (365 km) using flat pedals and shoes. I had to take pain medication occasionally, but I managed. On my return home I noticed my knee was able to move better, so I changed pedals and shoes to XT double sided and spd cleats.
I clipped in for only a short time at first, but yesterday I was clipped in for the whole ride.
The problem I have now is my hamstrings are really sore. Could clipping in cause the pain or is it a set up problem?
