I had the knee infection Dec/15/23 , the first operation they just opened me up and did a clean out of the joint, was on an antibiotic pump for 2 months , 2 days after i was finished the antibiotics i was still infected so then they removed the metal from a 2018 knee replacement and put in the antibiotic infused cement spacer, i did not have a cast but was able to hobble around for 3months until they performed the TKR May/28/24, with all the bone loss from 2nd surgery doc installed longer stems than normal ,nearly 4 months out i am dealing with stem pain in my shin and right hand calf area, at times this is very painful like a very severe case of shin splints some days okay some days are terrible pain still ! Doc says body has to adjust to the stem driven into the bone , it can take a long time to adjust , maybe year or more
