Articular cartilage injury microfracture under weight bearing with straight leg overtime protection (0-2 weeks)
Day of surgery.
After anesthesia subsides, begin to move toes and ankle; if pain is not significant, try to contract quadriceps. That is, tensing and relaxation of the anterior thigh muscles.
The day after surgery: 24 hours after surgery, you can walk on your feet without touching the ground by holding the double crutches (only to the toilet!)
1. Ankle pump: forceful, slow, full range flexion and extension of the ankle joint, as much as possible while awake. (Important for promoting circulation, decreasing swelling, and preventing deep vein thrombosis)
2.Quadriceps (anterior thigh muscle group) isometric exercises: i.e. thigh muscle tensing and relaxation. Do as much as possible without increasing pain. (More than 500 times / day)
3, N rope muscle (posterior thigh muscle group) isometric exercise: the affected leg force down the padded pillow, so that the posterior thigh muscle tense and relax. Requirements as above, more than 500 times / day.
4, correct position placement DD affected leg elevated on the pillow, toe to the top, not crooked to the side, below the knee joint should be empty, not to use the pillow to cushion the leg into a slightly bent position. If the pain is unbearable, it is placed in a comfortable position under the guidance of the doctor.
5. CPM exercises: 8 hours/day. Or perform flexion exercises on your own: sitting position, remove splint, completely relax the affected leg, hold the knee joint with both hands, lift and lower the joint to make passive flexion and extension (the angle range varies according to the cartilage injury site), 8 hours/day. This exercise was continued until 8 weeks postoperatively. Immediately after the flexion exercise, ice is applied for about 20 minutes. If there is usually a significant feeling of heat and swelling in the joint, ice can be applied 2-3 times/day.
2 days after surgery: drainage removal or no drainage
1.Continue the above exercises.
2.The ankle pump is changed to anti-gravity exercises (can be assisted by others or hold the thigh by hand). Doing this after each time you get out of bed can effectively prevent swelling.
3.Start side leg raise exercise, 30 times/group, 2-4 groups/day, rest 30 seconds between groups.
4.Start posterior leg lift exercise, lying prone (face down on the bed), lift the affected leg straight backward until the toe is 5 cm above the bed surface for 1 time, 30 times/group, 2-4 groups/day, rest 30 seconds between groups.
2-4 weeks after surgery
1.Continue and strengthen the above exercises.
2.In addition to daily small passive flexion, practice 1-2 times a week up to 120° of flexion and gradually increase the angle to avoid adhesions. 5-8 weeks postoperatively.
1.Passive flexion up to 120-130°.
2.Start weight-bearing and balance exercises at 8 weeks after surgery: 5 minutes/time, 2 times/group, 2-3 groups/day.
8-10 weeks after surgery
1.Start front-to-back and side-to-side striding exercises: slow, controlled movements and no swaying of the upper body are required. 20 times/group, 30 seconds interval between groups, 2-4 groups in a row, 2-3 times/day.
2, static squat exercises: squat to a pain-free angle, adjust the distance of the foot from the wall, so that the knee has been perpendicular to the tip of the foot squat angle less than 90 °. In the painless and controllable maximum angle to maintain two minutes 1. 2 minutes / time, 5 seconds interval, 5-10 times / group, 2 groups / day.
3. Aim to achieve normal gait walking.
10 weeks-3 months after surgery
1.Start single knee squat exercises: squat in the range of 0-45°, requiring slow, controlled movements and no swaying of the upper body. If necessary, lift heavy objects with both hands to increase the difficulty of the exercise. 20 times/group, 30 seconds interval, 2-4/consecutive groups, 1-2 exercises/day.
2. Patients who are able to do so and whose joint swelling and pain are not obvious can start stationary bike exercises to improve joint flexibility. No load to light load. 20-30 min/time, 2 times/day.
3. Seated resistance knee extension: use sandbags, etc. as load exercises, 30 times/group, 30 seconds rest between groups, 4-6 consecutive groups, 2-3 exercises/day.
After 3 months postoperative
1, daily prone position flexion so that the distance from the heel to the hip is the same as the healthy leg, continuous stretching 10 minutes / time.
2.Step front down exercise: 20 times/group, 30 seconds interval between groups, 2-4 groups continuously, 2-3 times/day.
3.Protected under full squat: 3-5 minutes / time, 1-2 times / day.
4.Start swimming, jumping rope and jogging.
