kemon ashchi Das babu? Thank you for asking the question. Being an Arthroscopy & sports injury surgeon I can tell you one thing for sure, you re already done with one life line..when it was a partial tear. Allow us to know whether an MRI is done,if so what specific ligament or meniscus is torn? You could get away on medicines and physiotherapy so far. But a complete tear of your anterior crutiate ligament (+/-posterior crutiate lig,+/- posterolateral complex) and a torn meniscus does warrant an Arthroscopic (pin hole) surgery. Unfortunately a torn crutiate ligament NEVER heals on its own. What needs to be done for ligaments is a RECONSTRUCTION using your Hamstring tendons(either Semi tendinosus or Semi membranosus or both) and partial or complete meniscectomy (removal) for torn meniscus(again depending on the type of tear). But let me tell you, these procedures have been very successful and the good part is that you might return to your sporting activity soon(with some good sessions of physiotherapy ofcourse). The only question now remains is WHEN to operate. Lets say an average of 6 months post injury. It depends on how early the swelling subsides and knee remains infection free. Till then I must say you have to complete a course of antibiotics, anti inflammatory medicines. You may use a hinged knee brace meanwhile to tackle the instability while walking. Hope this helps you decide the course of action. You need to go to an Arthroscopy & Sports injury surgeon. Do mail for more info. Bhalo theko
