"   Question I have been told that I have (pigmented villonodular synovitis) PVNS and I have been recommended open knee surgery (front and back). In your opinion, is this a good choice? What is my recovery period likely to be? Would it be a guarantee that I am free from the disease?   Answer I am sorry to hear you are suffering from this relatively uncommon problem. The treatment of this is still somewhat open to discussion among the experts, but my own view is that knee surgery appears to have a very good success rate, especially in the hands of an experienced orthopaedic surgeon \u2013 an important point. Recovery usually takes between four to eight weeks on average, and although no one will ever give you a 100 per cent guarantee of it never recurring, I would have thought that a figure of at least 80 per cent cure would not be argued with. I hope you have found this information of use, and good luck.
