The day after meniscus suture surgery and 1 day after surgery 1. Immediately after surgery, apply pressure bandage, elevate the affected limb, and fix it with a straight splint; after the anesthesia subsides, start to try: ankle pump-force, slow, full-range dorsiflexion and extension of the ankle joint, 5 minutes/group, 1 group/hour. (Important for promoting circulation, reducing 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. (greater than 500 times / day) 3, N rope muscle (thigh muscle group) isometric exercises – the affected leg force down the pillow, so that the thigh muscle tensing and relaxation. Requirements as above, greater than 500 times/day. 2 days after meniscus suture 1, start to try straight leg raising – extend the knee and then raise the leg straight up to the heel of the foot 15M from the bed, hold it until exhaustion. 10 times/group, 2-3 groups/day. 2.Start leg raising exercises in all directions, 30 times/group, 2-4 groups/day, rest 30 seconds between groups. 2-4 weeks after meniscus suture 1. Continue and strengthen the above strength exercises. 2. 2. Begin “kicking the hamstring” exercises to strengthen the legs. As appendix 1-figure 19 appendix 2-figure 4, 10, 11. 30 times/group, 30 seconds rest between groups, 4 groups consecutively, 2-3 times/day. 3.Increase the passive knee flexion angle by about 10° every week. 4 weeks after meniscal suture 4 weeks after meniscal suture should strengthen the strength exercises; passive knee flexion to 120°; active knee flexion to 90°; start to practice rotating the calf, range until just natural stop; start partial weight bearing, load about one-third to one-half of body weight. Recovery of weight-bearing period after meniscus suture 5-7 weeks after meniscus suture 1. 5-7 weeks after meniscus suture, weight-bearing of the affected limb gradually increases, and it can be fully weight-bearing at six weeks after surgery; weight-bearing and balance exercises – separation of the feet under protection, within the range of slight pain Move the center of gravity left and right alternately, and gradually transition to standing with one leg fully weight-bearing, 5 minutes/times, 2-3 times/day. 2, 5-7 weeks after meniscus suture surgery, continue to carry out passive knee flexion exercises with the help of the doctor, but the angle of passive activity is maintained at 120°; 3, flexion and extension of the knee 0-30 ° strength exercises, 30 times / group, 2-4 groups / day, 30 seconds of rest between groups; 4, flexion of the knee 30 ° semi-squatting ;, 2 minutes/repetition, rest 5 seconds, 10 consecutive times for 1 group, 2-3 times/day. Recovery of activity period after meniscus suture surgery 3 months after meniscus suture surgery 1, gradually resume strenuous activities, or special training. 2. Strengthen the muscle strength and the stability of the joints during running and jumping. 3, through the test, the affected muscle strength reaches more than 85% of the healthy side, there is no pain in exercise, no obvious swelling, then you can fully resume exercise. CONCLUSION: Recovery after meniscal suture is getting more and more attention, and it becomes an important factor affecting the postoperative cure rate. Through the recovery after meniscal suture, the postoperative quality of life of patients can be improved.
