Hello everyone. I am 5 days post op from having my LTKR. The past 2 days I have been struggling with pain, but what concerns me is I have no quad strength. I feel like my brain isn’t communicating with my quads. I’m on a cpm about 4-6 hours a day. I can reach 0 on extension and about 75 on flexion. My leg feels tight at all times. How long does it take to regain strength? This is really frustrating me.
