The method comprises the following operation steps:

1. if the anterior meniscus, body and lateral posterior meniscus have been sutured, needle one 2 will be used. An example is a horizontal tear row "hug" stitch of the lateral disc meniscus involvement red zone. Firstly, partially cutting and forming a meniscus part → bending a diseased limb to a character 4 → freshing a torn wound surface → monitoring an anterolateral approach, placing a proper positioning sleeve 1 in the anterolateral approach, placing the positioning sleeve 1 on the upper surface of the meniscus of the torn part in parallel, and enabling the inclined end of the positioning sleeve 1 to abut against a joint capsule as much as possible. Method one (double needle): an assistant respectively penetrates two ends of a 2-0 absorbable or non-absorbable suture line with the length of 900mm into the threading hole of the two suture needles I2 to be reversely folded at a position of about 50mm → the sharp tip of any suture needle I2 is inserted into the positioning sleeve 1 until the whole suture needle penetrates out of the body surface → the suture is taken out from the threading hole → the positioning sleeve 1 is placed on the lower surface of the corresponding meniscus (the suture on the upper surface is taken out of the joint capsule site) → the other suture needle with the thread is pulled out of the body by the same method → the suture is pulled out of a small incision in the middle of the two sutures on the body surface to be knotted and fixed under the skin so as to finish one-time 'embracing' suture; method two (single needle): an assistant penetrates one end of a 2-0 absorbable or non-absorbable suture line with the length of 900mm into a 2-hole of a suture needle to be reversely folded at a position of about 50mm → the needle hole end of the suture needle with the line is inserted into a positioning sleeve 1 until the needle hole penetrates through skin → a small hemostatic forceps clamps the head end of the inner thread of the needle hole → a handle 11 is held to withdraw the suture needle 2 into the sleeve → the positioning sleeve 1 is moved to the lower surface of a meniscus corresponding to a joint capsule position by referring to the route of the suture thread penetrating through the joint capsule on the upper surface → the first needle step → the thread head is taken out from the needle hole penetrating through the skin → the positioning sleeve 1 together with the first suture needle 2 is withdrawn from the joint → the suture thread is pulled out of the small incision in the middle of two suture threads on the body surface to be knotted and fixed under the skin so as to finish one-time looping suture.

2. For the medial meniscus posterior angle stitch, stitch needle two 3 will be used, taking as an example the vertical tear row "hug" stitch with the medial meniscus posterior angle compromising the red-white interface. The proximal straightening valgus position probe of the knee joint measures the distance from the free edge of the meniscus to the posterior edge of the platform → selects a proper approach (the direction of the approach deviates from the posterior midline as much as possible) to directly put a suture needle II 3 with scale marks (at the moment, an assistant has penetrated one end of a 2-0 absorbable or non-absorbable suture thread with the length of 900mm into a hole of the suture needle II 3 for about 50mm to be reversely folded) → puts the suture needle with the thread on the synovial edge of the upper surface of the torn meniscus → slowly penetrates through the joint capsule according to the depth measurement distance → the other end of the suture thread penetrates into another suture needle II 3 in the same approach → puts the lower surface of the corresponding meniscus of the first needle and slowly penetrates → if a plurality of needles are needed to be sutured, the steps are repeated → the slow knee 90 DEG passes the arthroscope between the posterior cross and the outer lateral wall of the femur to enter the posterior medial compartment → monitors the depth of the lower adjustment insertion needle → the forceps respectively get out of the needle head and pull out the needle from the front of the body → simultaneously withdraws the suture needle to fix the suture needle through the posterior approach to fix the suture.

The suture of the posterior horn of the lateral meniscus does not need to change the body position, namely under the state of the 4-shaped bent knee position, the proper approach is firstly selected to be positioned by the aid of the positioning sleeve, then the arthroscope is switched to the posterior lateral chamber through the intercondylar, the needle hole end with the thread of the suture needle I2 is inserted into the posterior lateral chamber through the sleeve under the monitoring, and the suture is knotted and fixed at the rear side through the posterior lateral approach.

The protection scope of the present invention is not limited to the technical solution disclosed in the specific embodiment, and all the modifications, equivalent replacements, improvements, etc. made by the technical entity of the present invention to the above embodiments all fall into the protection scope of the present invention.
