Most patients recovering from partial knee replacement surgery must walk with a cane or a walker for three to four weeks after the surgery, according to MedlinePlus. Patients typically need another four to six months of physical therapy. They should not jog or participate in high-impact sports during that period.
Recovery from a partial knee replacement is faster than recovery from a total knee replacement. Most patients go home from the hospital the day after the surgery and are encouraged to put weight on their new knees immediately. A partial knee replacement is typically performed to relieve severe arthritis pain, as MedlinePlus explains.
