Its has been more than 4 months after my surgery was done for removal of Giant Cell Tumor from right distal femur region of my right knee. I am able to bend my legs till 120 degrees but the movement is stil not free the bending starts from 105 degrees and goes upto 120 degrees as i do more repetition. Also in extension i have a lag of 20 degrees i can extend  my legs till 160 degrees actively and passively i can do till 180. I am continuing with my physiotheraphy excercise regularly. Kindly let me know the next steps and any timeline by which i should achieve full movement both in extension and flexion. Attaching are images of my extension and flexion active range
