Indeed. Partly it’s swelling due to the arthritis, pain due to the damage to the bone surfaces in all three compartments, partly due to muscle imbalance between quad, hamstring, calf. There may not be a solution, but giving the physio a go (compex sessions and gym work)
Gained nothing in terms of bend in 6 weeks though. I did manage 5 miles clipped in however a couple of weeks ago. 4 or 5 months ago I couldn’t even turn the pedals 5 times clipped in without excruciating pain!!
If it stays dry, I’ll give it another go with the cleats at the weekend
