Hi, It is common to have joint contractures / stiffening in child Chat Doctor.  This is because of abnormally high muscle tone. If we are able to straighten the knee fully passively, this indicates a dynamic contracture which will respond to intensive physiotherapy. If stiffening is severe enough to prevent full straightening, this indicates static contracture demanding surgical release, as done before for ankle joint. Kindly discuss with your orthopedist and physiotherapist. Hope I have answered your question. Let me know if I can assist you further.
