According to the Mayo Clinic, total knee replacement surgery, is one of the most successful elective surgeries done today. Exercising consistently with a physical therapist and at home is key to ensuring a successful return to activities of daily living and recreational exercise. The Mayo Clinic reports that about 90 percent of patients have freedom from pain and improved mobility for up to 15 years after the surgery.
Quad Sets and Straight Leg Raises
The American Academy of Orthopaedic Surgeons recommends beginning quad set and straight leg exercises in the recovery room. To perform, the patient tightens the thigh with the leg straight on the bed and holds for 10 seconds. Once that is comfortable, the patient tightens the thigh, with the leg straight, and attempts to lift it six inches off the bed for 10 seconds. Straight leg raises can be performed with ankle weights for more advanced strengthening later on in the rehabilitation process.
Walking
According to The American Academy of Orthopaedic Surgeons, proper walking is the best way to help the knee recover following total knee replacement surgery. The patient is encouraged to begin walking around the hospital room, with the aid of a walker immediately following surgery. Weight bearing is increased as tolerated by the patient, until the walker is no longer required. The patient is encouraged to walk throughout the rehabilitation process, three times per day for 30 minutes.
Exercise Bike
The exercise bike will help the patient regain knee range of motion, as well as increase strength. Initially, the patient will rock the pedals back and forth, as far in each direction as he can, until a complete revolution is performed. Once the patient can pedal the bike normally, he is encouraged to ride for 15 to 30 minutes, three times per day. Resistance can be increased on the bike as tolerated.
Step Ups
The leg muscles can be strengthened by utilizing the bottom stair as an exercise device. The foot of the affected leg is stepped onto the stair and remains there for the complete exercise. Facing the stair, and holding onto the railing for balance, the patient steps up, leading with the affected leg, and steps down, leading with the opposite leg. The exercise should be repeated 10 to 15 times.
