Hi there!
You are showing good progress at six weeks of replacement. I would suggest giving the discomfort/ pain some time to settle as you continue with the physiotherapy. Hopefully it should settle with time. However if it is severe or there are additional symptoms, you may consider a review with your treating orthopedician.
Hope this is helpful.
Take care!
many thanks. I have just had my other knee done last week (8 weeks between knees) and had discussions with my consultant who said the same thing. He reckons the ops went well and the pain may well be ligament and or the healing process. Hopefully this knee gives me less bother than the first one which is now taking more of the weight. Patience is a virtue!!
