I ve had a locked out knee for 6 weeks . Can t fully bend or extend it. I ve had this problem since age 19 , I m now 54 .Past X rays showed a bit of floating bone . Past scan advised nothing wrong , yet this has happened a dozen times, more so when pregnant . In the past I ve had it manipulated back whilst under . This time I ve been left untreated and need you to tell me how long l can expect to be immobile please . I m broken & no one will fix me !!!!! Desperately seeking advice , yours in anticipation , Heather Jane Freeman .
