It sounds all normal to me! I was at about 87 degrees flexion at around 3 weeks post-op too, a little slower than with my first knee but continued to have improvements as the weeks went by.
Keep icing, elevating and resting as much as you can too. You are still healing and it's still early days for that baby knee.
