Aloha i am 49 yrs old and very bow legged bone on bone on the inside compartments of both knees. I had a HTO on left knee 3 months ago. I did as instructed no weight bearing for 8 weeks. Well just yesterday i stepped wrong and did not really feel extra pain(the both knees are in constant pain daily) but i notice the leg is bent. It looks like the surgey might not have taken.. OMG is this possible. Ive been so good about this.. Is this a possibility. Has anyon had this happen. I have a call into the surgeon i am scared.
