The harm of meniscus injury: pain takes place in 1) arthralgia, knee joint when a certain position, and after changing position, pain can disappear; 2) amyotrophy, based on quadriceps femoris, since meniscal damage, the knee joint limitation of activity, with the passing of time muscle has produced disuse atrophy, and amyotrophy is serious more, and the weakness of the lower extremities phenomenon is also obvious more; 3) walking disorder, meniscus has promptly partially or completely been lost its original function because of after long term wear or acute injury break, even forms at intraarticular and to disturb, and locked joint and snap occur, influences kneed proper motion, causes the puzzlement of walking disorder.
Meniscus injury is difficult for healing usually, because meniscus blood fortune extreme difference, the overwhelming majority is an avascular area, has only the outside just near the 25%-30% of joint capsule side blood supply to be arranged, so extremely difficult healing after the meniscus injury.Should in time treat according to degree of impairment once making a definite diagnosis promptly, adopt expectant treatment in the past,,, shank be tried one's best stretch after the flexing, can remove the locking of knee symptom by interior external rotation shank as manipulation; Or immobilization treatment, by braking, drawing liquid, with Elastic bandage wrapping, with 45 ° of clamping plate or plaster fixation knee sprungs.
The meniscus suture is to treat the optimal modus operandi of meniscus injury at present, the many ecto-entads of meniscus are sewed up, the general meniscus sewing needle that adopts during stitching, a kind of meniscus sewing needle is disclosed as CN202426582U, contain shank, an end of shank is associated with bow, and the front end of bow is a needle point, the pin hole that passes for suture is arranged on the bow, and the other end of shank is associated with handle and barre.Its needle point is sharp, can not cause the meniscus secondary injury when passing meniscus, and suture passes pin hole and introduces articular cavity, can avoid the suture fracture, and the shank front end is associated with bow, and is more adaptive with articular cavity.And for example CN102626332A discloses a kind of meniscus suture instruments, and is with low cost, simple in structure, easy to operate.But in order after puncture, to introduce suture, the sewing needle diameter of at present used hollow is thicker, is difficult to arrive ideal position when causing the sewing needle puncture by meniscus, and if in order to arrive ideal position, need repeatedly puncture, will cause damage meniscal tissue.
