###Human: Had PCL surgery before five weeks. When can I walk without support? ###Assistant: Hello. You had a PCL (posterior cruciate ligament) injury five weeks back which was managed by a screw fixation. I have seen both your pre-operative MRI scan and a post-operative X-ray (attachment removed to protect patient identity). In my opinion, you can continue with the use of knee ROM brace with intermittent knee movements, crutch aided PWB movement for one more week and then crutch aided full weight bearing ambulation. Repeat X-ray after four weeks, and maybe 6 to 8 weeks post-surgery, the patient can be made to ambulate without any support depending upon initial reduction and subsequent healing. So, as of now, you can go to your office with the help of crutches and partial weight bearing on the operated leg.
