Knee rehabilitation following surgery usually incorporates multiple steps or phases. The last phase is the advanced phase, and usually progresses from short, end-range exercises to more functional and challenging exercises. The purpose of this phase is to return you to previous levels of activity and function. You should not attempt exercises in this phase without clearance from your physician or physical therapist.
Step-Ups
Step-ups are a functional exercise that works to strengthen the quadriceps muscle and return stability to the knee. Generally after surgery, you are instructed to ascend stairs with your nonsurgical leg first, and descend with your surgical leg first. To use step-ups as an actual exercise, lead with your surgical leg. Begin with a step of 3 to 6 inches, and increase the height of the step to make the exercise more challenging. Once on top of the step, step backwards off the step with your uninvolved leg first. Repeat this exercise 10 times, twice per day.
Lateral Step-Ups
Lateral step-ups, or sidestepping, is an effective exercise to develop strength, stability, and balance. Use the same height step from the first exercise. Start with the step on the same side as your surgical leg. It is important to keep your toes pointed straight ahead during this exercise. Step up onto the step with your surgical leg. Bring your other leg up to the step, and slowly step back down, leading with your nonsurgical leg. Repeat this exercise 10 times, twice per day.
Terminal Knee Extension
Terminal knee extension exercises work to make sure you are straightening your knee fully. Sitting with your feet straight out in front of you, place a small towel roll under your surgical knee, so your knee is slightly bent. Squeeze your thigh muscle, lifting your heel off the ground until your knee is straight. Hold this position for five seconds. Slowly lower your leg to the starting point. If this exercise is too easy, try adding small ankle weights, in 1/2 lb. increments.
Walking Program
Beginning a walking program is an excellent idea at this point in your knee rehabilitation. If you have been using crutches, make sure you have clearance to begin bearing weight on your knee without them before beginning a walking program. Start slowly, walking around the house or on a level treadmill for five minutes or less. Gradually increase your walking time as you incorporate it into your other exercises. Consult your physician or physical therapist for specifications for your walking program.
