I had a LTK in July 2022 and an MUA in Nov 2023. My flexion is 120 and extension is ok. I have constant pain; feel like modeling clay is around outer knee. My first PT was very rough. My PT after MUA did lots of slow stretching, eastern type "spooning", water exercise and saved my movement. Now I am trying to deal with pain. I can't stand for any long periods but can walk. Hope to learn more.
The pain with standing sounds like an inflamed Hoffa's fat pad being pinched between the bones of the knee when you have weight on it. There can be less pain from walking because the other knee takes the weight half the time, and the bones aren't always being pressed together so hard at different points during walking. An MRI or ultrasound by an experienced radiologist looking out for fat pad issues should indicate if this is your problem, but it sounds likely. If it is an inflamed Hoffa’s then you could try to minimise standing and even walking, as well as activities such as steps, squats etc and try to settle it down. Some people use crutches or a wheelchair for 6 to 8 weeks, it is likely to take a long time. I hope this helps.
