6 months. The most rapid phase of recovery is in the 1st 6 weeks, but full recovery from tka can take 6 months or more. The bone and soft tissue healing take time, as does regaining strength.
2-3 months. 2-3 months for most people for many activities; sometimes much longer. It can take up to 18 months for "full" recovery.
