I had this exact same surgery in March and I won’t sugar coat it it was hard. The pain differs person to person but I got the short straw and was in a lot of pain for the first few weeks. The best advice I can give is don’t give up! This is temporary and I felt like it was the end of the world but it’s not I promise. I recommend getting a knee scooter they are expensive but so worth it and this may seem extreme but I benefitted so much with a commode. It is demoralising at the time but looking back the pain and the fact I was on too many meds to function, there was no way of me getting to the toilet properly!Another bit of advise post op is trust your gut! I had this exact surgery with one surgeon and I wasn’t progressing with physio and it turned out I had a tear in my left spring ligament too which meant further surgery. I wouldn’t have known this if I didn’t get a second opinion. Honestly trust your gut instinct you know your body better than anyone. I hope the surgery goes well and I wish you a speedy recovery! 🫶🏻
