A knee flexion of 125° and over is typically the end goal set for total and partial knee replacement patients. A study that measured the knee flexion in 100 knees a year after a total replacement saw a mean flexion of 125°. At this range of motion, most people can carry out almost all normal activities.
You asked, how far can you bend your knee after replacement? Within 7 to 10 days after your knee replacement, you should be able to get your knee entirely straight/full extension (Fig. 1) (no space between the back of your knee and the table) and you should be able to bend/flex your knee to at least 90 degrees (Fig. 2).
You asked, how long do you keep your leg straight after knee replacement? After 7–10 days, you should be able to fully extend your knee out straight. Your knee may be strong enough that you’re not carrying weight on your walker or crutches anymore. Most people are using a cane or nothing at all by 2–3 weeks.
Beside above, what happens at 4 weeks post op knee replacement? Knee pain and function greatly improve during the first few weeks after knee replacement surgery. Significant improvements continue during weeks 4 through 6. By week 6, the majority of patients are off pain medications and have resumed their day-to-day routines.

Why can’t you bend your knee after TKR?
