Sir my right knee (ACL) ligament was tore while playing. So I took treatment and get it reconstruct through a doctor. He inserted screw in knee. Now 10th month is going on after operations. But still I am having pain in my knee when I sit in latrine. Specially after running or if I stand for more than an hour. I did many exercises also for this. I am in army so I have to do hard work. Please advise me some medicine or exercise s to overcome this stiffness of knee. In running I have no problem but I have problem in fully bend of leg.
