Recovery after knee surgery typically takes about 12 weeks, according to Healthline. This recovery time estimation is dependent on adherence to crucial post-surgery rehabilitation steps along with a high degree of commitment and self-discipline.
Knee surgery patients generally start rehabilitation immediately with walking and standing aids, according to Healthline. Physical therapy sessions focus on immediate use of the new artificial knee, starting with short standing and walking exercises. Within a few days, the patient moves from a bedpan to a regular toilet, begins walking on stairs and has 90 degrees of bending mobility. Patients are usually discharged after a few days and spend the following three to six weeks getting around in and out of the house and sticking to an exercise regimen. Range of mobility, strength and mobility typically increase by week 11 or 12. After 13 weeks, it is important to keep active and check in with a doctor regularly.
