post-operative knee pain ( > 1 year out)

Hi, What is a good treatment for post-operative knee pain 1 year out (TKA), negative work-up of infection (3 phase scan, infecitous labs, no mechanical instability) Assuming, no genicular nerve block/ablation is option, no pes-anserine bursa. Does someone have streamlined approach to this? Would love review articles/approaches
