My left hip was replaced Nov. 27th, 2018. I felt ready to ride in 2 weeks. Truth. I spoke with the surgeon 24 hours after surgery and he described to me that any pain should feel like a bad bruise. He was spot on. Got rid of the walker on day 2. Got rid of the crutches day 6. Got rid of the cane day 9. I was mobile in short time. I could have rode the bike at 2 weeks but the surgeon said at 6 weeks I could do it. First bike ride was one month after surgery. I rode all winter with no issues and the hip feels great today. Right knee gets done Sept 23rd. I delayed that 6 months. I fear it. Hip is the least complicated joint in the body. The knee is the most complicated joint in the body. Oh God..... Its gonna hurt. Robot assisted. Oh boy...
