@Walkinginthesand - my recoveries were both different even though I had same surgeon and same approach (posterior). With the first one I was still using cane at the point you’re at and had difficulty with chairs because it felt like I had a tennis ball in my butt cheek. With my newest replacement I’m already off cane unless the leg is tired. I’m only able to sit in one chair at the moment (precautions) but I don’t think I’ve got the tennis ball thing like last time either. Hang in there - patience can be difficult.
