For a successful recovery from knee surgery, rehabilitation exercises must begin the day after surgery and be modified as recovery progresses. The post-op recovery plan outlined involves exercises like ankle pumps, leg raises, and isometrics to be done multiple times daily for the first few weeks. Exercises gradually progress to include walking, sitting, stair climbing, and strengthening workouts over 6 weeks. Patients are advised to follow the customized plan and understand recovery will differ for each individual.
