Table 2 Hip and knee preoperative exercise programs

From: Feasibility of a preoperative strengthening exercise program on postoperative function in patients undergoing hip or knee arthroplasty: a pilot randomized controlled trial

Weeks Hip Knee
1 Supine hip glide: While the patient is lying prone with a pillow under the torso, he/she will slightly lift the operative leg and move it sideways through as much range as the hip allows. The leg will then return to the start position. Knee extensions supine: While the patient is lying prone with a foam roller beneath their thigh on their operative side, the patient will lift his/her heel off of the floor as high as he/she can then return the leg to starting position.
2 Standing hip abduction: The patient holds on to a horizontal surface for equilibrium, such as a table or counter. The patient abducts the operative hip through as much range as the hip allows and returned to the starting position. Sitting knee extensions: The patient will sit in a chair with his/her back straight. The operative knee will be straightened as much as possible then returned to starting position.
3 Side-lying hip rotation: The patient will lie on his/her non-operated side, with the hips straight and knees bent 90°. A pillow is placed between the knees. The hip is then externally rotated through as much range as the hip allows and returned to the starting position. Partial squat: The patient will stand straight using support from a table or chair with feet shoulder width apart. The patient will perform a semi-squat then return to starting position.
4 Side-lying hip rotation with elastic: The same position as the week 3 exercise, but an elastic will be placed above the knees. Mini-squat: The patient will stand on their operative leg, using a table or chair for balance. The patient will bend their support knee slightly then return to starting position.
5 Leg abduction with elastic: The same exercise as week 2, but with a yellow elastic band placed just above both ankles. The length will be determined so that elongation is at 200% at a maximum range of motion of the hip of the patient. Step-up: The patient will stand with his/her operative knee on a stair. The patient will slowly shift weight onto their operative leg on the stair and step up, then step back down leading with their uninvolved leg.
6 Side-lying abductions: The patient will lie in the same position as weeks 3 and 4. However, their top (operative) leg will be straight. The patients will move their leg supine for ~ 6 in. then return to the starting position. Sit to stand: The patients will place a chair with their backs against a wall for support. The patients will sit on the edge of the chair, fold their arms across their chest, and sit such that their knees are bent over their toes. The patients will lean forward and stand up fully, then return to starting position.
