    • An anchor system that is preferably for use in an arthoscopic cruciate ligament replacement procedure for securing a ligament (37) or (50), or ligament type device, with or without a stint (38), within a prepared ligament tunnel (33). The system includes a pair of threaded footings (11) for turning in opposite tapped ligament tunnel cortex ends (34) and (35) and studs (10), each having an eyelet end (18) or, for a prosthetic ligament (50) is secured to the ligament end, the studs each having a cylindrical body (17) and flared end (12). The stud flared end terminates in a lip (15) wherefrom a lock wall (16) extends at an angle to the vertical to the cylindrical body, which flared end is cross-cut at (19) and (20), forming sections. The stud flared end (12) sections to close together to fit through the threaded footing (11) and flex outwardly beyond that footing end (24), the lip lock wall (16) to flex over that footing end locking the stud therein.In practice, the ligament (37) with or without the stint (38) is formed into a loop for sliding along the stud (10), slot (20) into the eyelet (18), or the studs are attached to a prosthetic ligament ends in its manufacture, the pair of studs and connected ligament and stint for manipulation through an arthoscopic port (36) formed into the patient's knee, each stud for seating into a threaded footing, the studs each locking therein with the ligament stretched across the knee intra articular joint. Whereafter, tension on the ligament can be adjusted by individually turning the threaded footings appropriately into or out of the cortex threads.

    • The invention provides a system for surgically implanting an allograft or prosthetic ligament as a replacement for a patient's cruciate ligaments. In a practice of the system, as a replacement for an anterior cruciate ligament, the patient's leg is bent and maintained at approximately a ninety degree (90.degree.) angle, a single incision is made medial to the tibial tuberosity. From this incision, under fluoroscopic and arthroscopic contol, a guidewire is driven through the tibia and across the cruciate ligament junctions with the proximal tibia and distal femur ends and into the femur cortex. Succesively larger drills are then turned along the guidewire to form a ligament tunnel, with, as a last step in the tunnel formation process, the preparation of the femur cortex end of the tunnel to receive a femoral connector of the implanted ligament, which connector is arranged in one embodiment to be outwardly flared and in another embodiment to be turned into the appropriately prepared femur end of the ligament tunnel to lock therein. The invention, in addition to the embodiments of the ligament femur end connectors, further includes a tibial surface ligament tibial end connector for both securing the ligament end to the bone and for setting ligament tensioning, of which ligament connectors can be manufactured from a biodegradable material for absorption by the body.
    • 本发明提供了一种用于手术植入同种异体移植物或假体韧带以作为患者十字韧带的替代物的系统。 在该系统的实践中,作为前交叉韧带的替代物,患者的腿弯曲并保持在大约九十度(90度)的角度,单个切口在胫骨结节内侧。 从这个切口,在荧光镜和关节镜轮廓下,导丝通过胫骨并穿过十字韧带与近端胫骨和股骨远端端部并进入股骨皮层。 然后成功地较大的钻头沿着导丝线转动以形成韧带隧道,作为隧道形成过程中的最后一个步骤,准备隧道的股骨皮质端以接收植入的韧带的股骨连接器,该连接器 布置在一个实施例中以向外扩张,并且在另一个实施例中被转换成适当准备的韧带隧道的股骨端以锁定在其中。 除了韧带股骨端连接器的实施例之外,本发明还包括胫骨表面韧带胫骨端连接器,用于将韧带末端固定到骨头并用于设置韧带张紧,其中韧带连接器可以由生物可降解材料 为身体吸收。

    • The improved channel ligament clamp of the invention is for human implantation in a surgical procedure for securing a ligament, that is either natural or prosthetic, onto a bone cortex and includes, as a clamp body, a rectangular section of a thin, flat metal material, such as titanium, with identical equal opposite edge portions of which material bent at approximately right angles forming upstanding parallel side walls. Edges of which upstanding parallel side walls are for contacting a bone surface whereto the clamp is secured to closely contain a ligament section therebetween without crushing it, and which parallel side walls are the side walls of a channel section with the flat material therebetween constituting the channel section web. Which channel section web includes a plurality of pointed end parallel pins secured thereto that extend at right angles and are parallel to clamp the side walls. Preferably four pins are employed with each arranged as a corner of a square pattern, and a hole that is preferably threaded, is formed through the web in the center of which formed square for passing a screw type connector therethrough.

    • An endosteal fixation for mounting a prosthetic or soft tissue graft or combination thereof, under tension at a cortex end of a bone tunnel and process for its use. The endosteal fixation stud includes a cylindrical body that is preferably manufactured from a somewhat resilient material, and is suitable for implantation in a human body. The cylindrical body is stepped outwardly, proximate to a rear end, into a bridge that has spaced rearwardly extending arms wherebetween the graft is secured. The cylindrical body forward end is split into equal parallel sections that can be flexed together, one of which sections includes a hook that extends and rearwardly, that will align with the cylindrical body surface when the two cylindrical body sections are compressed together. The endosteal fixation stud can be arranged to be pushed or pulled through a bone tunnel.A single endosteal fixation stud is utilized to mount a graft and to the cortex at a bone tunnel end, the graft extending therefrom through the tunnel and out the opposite bone tunnel end, whereat it is bent and secured under tension, as with a staple, to the cortex surface adjacent to that bone tunnel end.
