After the meniscus anterior and posterior horn injury suture surgery, the affected limb can be weight-bearing at an early stage, and the affected limb will not be weight-bearing within four weeks after the meniscus body injury suture surgery and will not be flexed within one week after the surgery.
I. Protection period (1 day to 4 weeks after surgery)
1. The first day after surgery.
Immediately apply pressure bandage, elevate the affected limb, and fix it with a straight splint. After anesthesia subsides, begin to try to.
(1) ankle pump ‘forcefully, slowly, and with full range of flexion and extension of the ankle joint, as much as possible. After dismounting, ankle pump exercises under anti-gravity can be performed.
(2) Quadriceps (anterior lateral thigh muscle group) isometric contraction exercises, i.e. thigh muscle tensing and relaxation. Do as much as possible without increasing pain.
(3) 3N rope muscle (posterior thigh muscle group) isometric contraction exercises, the affected leg force down the padded pillow, so that the posterior thigh muscle tense and relaxation. Requirements as above, greater than 500 times / day.
2.The second day after surgery.
1.Start to try straight leg lift, straight leg lift after knee extension until heel is 15cm from bed, hold until exhaustion. 10 times/group, 2 to 3 groups/day.
2.Start leg lifts in all directions, 30 times/set, 2 to 4 sets/day, with 30 seconds rest between sets.
3.1 week after surgery.
(1) Continue and strengthen the above strength exercises.
(2) Passive knee flexion to 90 degrees.
4. 2-4 weeks postoperatively.
(1) Continue and strengthen the above strength exercises.
(2) Start multi-angle isometric resistance knee extension exercises to strengthen the leg. 30 reps/set with 30 seconds rest between sets, 4 sets in a row, 2-3 times/day.
(3) Increase the passive knee flexion angle by about 10 degrees per week.
5.4 weeks after surgery.
(1) Intensive strength exercises.
(2) Passive knee flexion to 120 degrees.
(3) Active knee flexion to 90 degrees.
(4) Begin rotating the lower leg in the range until it just stops naturally.
(5) Begin partial weight-bearing with a load of approximately one-third to one-half of body weight.
II. Return to weight-bearing period (5 to 7 weeks after surgery)
Do not walk too much during this period, otherwise it will easily lead to joint swelling and fluid accumulation, which will affect functional recovery and tissue healing.
1. Gradually increase the weight-bearing of the affected limb, and gradually put on full weight 6 weeks after surgery.
Weight-bearing and balancing exercises, separation of both feet under protection, alternating left and right weight shifting within the range of slight pain, gradually transition to full weight-bearing standing on one leg, 5 minutes/time, 2 to 3 times/day.
Separate both feet anteriorly and posteriorly, move the center of gravity, and gradually transition to full weight-bearing standing on one leg.
2. 5 to 7 weeks after surgery, continue passive knee flexion exercises with the help of the surgeon, but maintain the passive angle at 120 degrees.
3, Flexion and extension knee 0 to 30 degree strength exercises, 30 reps/set, 2 to 4 sets/day with 30 seconds rest between sets.
4.Flexion and extension knee 30 degree half squat, 2 minutes/repetition, rest 5 seconds, 10 consecutive sets, 2 to 3 times/day. (For those with patellofemoral joint symptoms, perform straight leg raise and 20 degrees to 0 degrees open chain knee extension training.)
III. Recovery period (8 to 12 weeks after surgery)
1. The affected limb can be fully weight-bearing 8 weeks after surgery.
2.Passive knee flexion over 120 degrees and active knee exercises at 8 weeks after surgery.
3.In order to strengthen the posterior thigh muscle group, start “hook leg” static exercises, bend to a painless angle for 10-15 seconds, 10 times/group, 4 groups/day.
4.Start the front-back and side-to-side straddle exercise, 20 times/group, 4 groups/day.
5.Fixed bicycle exercises, no load to light load. 10-20 min/set, 2 sets/day.
6.Athletes can start the training of basic technical movements of special sports three months after surgery. But must be gradual!
Knee pads can be worn for protection if necessary, but only advocated for use during strenuous exercise.
IV. Recovery period (after 3 months)
1. Gradually resume strenuous activities or special training.
2.Strengthen the muscle strength and the stability of the joint during running and jumping.
3.Through the test, the muscle strength of the affected side reaches 85% or more of the healthy side, and there is no pain and no obvious swelling in the movement, then the movement can be fully resumed.
