Hello. For the last 2 months I ve had major problems with my left knee. Can t lift leg up from a seating position. It feels like its going to hyperextend when I walk. Can t walk normal anymore. Not sure if I tore or separated a mcl or something. The main problem is that it s not getting any better.
Hello, What I understand that the knee is too weak now to take the weight of the rest of the bones below the knee. Are you having any kind of pain? What is your age and are you having any signs of high blood pressure or diabetes?  Kindly get it Physically examined by an orthopedist and do an MRI scan of the knee. The history sounds more of the full ligament tearing. Taking immediate action will be good as if avoided later the knee internal structures which are of course soft tissue will get damaged and land into the early signs of Osteoarthritis of knee and will demand knee replacement. The earlier, the better. Take an MRI and meet up and orthopedist at the earliest for the better outcome of the treatment. Hope I have answered your query. Let me know if I can assist you further. Take care Jay In Chat Doctor.
