im 34 years old and 10 weeks po TKR. I have flexion of only 48. Recovery has been very tough. At 3 days po I got cellulitis and was in the hospital for some time. Orthopedic kept saying continue PT when therapist told him knee isn't moving. He scheduled me for a MUA 5 weeks from now. My concern is having an MUA at 15 weeks. I read that it isn't safe. Also would like to hear others thoughts on my situation.
