Description
Technical field
The present invention relates to the single tunnel in anterior cruciate ligament femur and tibia stop footmark district and dissect the reconstructing system field of beam splitting and the preset autologous or allosome tendon of primary tension force, be specifically related to a kind of orthopaedics anterior cruciate ligament of knee joint Anatomical Reconstruction system and using method thereof.
Background technology
Kneed anterior cruciate ligament, be called for short ACL, refer to be attached to after knee joint femoral lateral condyle medial surface, after upper, outer dense connective tissue assembles in intercondylar fossa, before oblique knee joint, under, in, terminate in ridge the place ahead depression between tibial plateau condyle and the ligament structure of formation.Its femur, tibia stop two ends have blood vessel to nourish and neural distribution, and major function is to control the abnormal reach of kneed tibia and rotation, matches and maintains kneed stability with kneed other static(al) and dynamical stability device.
But, once ACL damage is repaired pretty troublesome.ACL reconstruction operations under traditional arthroscope, mainly rebuilds AM and restraints by drill through respectively single osseous tunnel on the isometric point of femur and tibia stop.When its a large amount of patient with operation are surpassed to the multicenter length of 20 years, follow up a case by regular visits to and show, its postoperative success rate is between 69% to 90%.Because it adopts footmark district, do not dissect location osseous tunnel, and do not rebuild PL bundle, therefore still have larger curative effect room for promotion.80 years last century, some scholars finds to drill through respectively AM and two osseous tunnels of PL in femur and tibia footmark district, can better simulate before normal ACL to and rotation tension force, Clinical Follow-up also demonstrates the better stability of more traditional isometric single point rebuilding tunnel technology and controls.But under its mirror, operate technical sophistication, need on femur and tibia, drill through respectively two osseous tunnels, and the use amount of interior fixedly consumptive material is the twice of single tunneling technique.Because bone loss after drilling through 4 tunnels in art is large, cause it and overhaul particularly difficulty, some patients were need to could be overhauled after 1 year again through first phase osseous tunnel bone grafting! Therefore, although the dissection of the ACL under arthroscope is bifilar, shin rebuilding tunnel has its theory advantage, but based on its high-tech difficulty, expense is multiplied and the difficulty of overhauling, international arthroscope main flow magazine < < Arthroscopy > > is when evaluating this technology, the comment of using is " two tunnels, dual trouble.Double?tunnels,?double?troubles”。
At present, the reconstruction operations of Most scholars agreement ACL should be located in the footmark district based on each patient's femur and tibia stop uniqueness, no matter use single tunnel in art, or twin tunnel, all should cover hand and foot Liang Ge footmark district, from dissecting location and functional structure, fully simulate ACL in knee joint is bent and stretched activity on a large scale before needed each angle to and rotational stabilization.
