Presented is a preoperatively designed guidance tool for intraoperative use during bone or joint surgery wherein the guidance tool is specific to the anatomy of the patient being treated. The guidance tool comprises a body portion, a mating surface provided on the body portion for positioning the guidance tool on a corresponding registration surface of a patient's anatomy. The guidance tool further comprises at least one guide mechanism provided on the body portion for guiding a medical instrument at one or more preoperatively defined trajectories relative to a patient's anatomy. In the event of misalignment, the at least one guide mechanism is adjustable to alter the one or more preoperatively defined trajectories if necessary during intraoperative use. Also presented is a preoperative process for designing the guidance tool.

Various embodiments are directed to a sheath for covering one or more components of an extra-articular implantable mechanical energy absorbing system. The sheath is generally an elongated structure having an inner space extending the length thereof. In use, the sheath can exclude the energy absorbing system from surrounding tissue and facilitate creating a capsule for its operation. Materials and dimensions are selected to achieve these purposes. The ends of the sheath include various attachment mechanisms for securing the sheath to one or more components of an extra-articular implantable mechanical energy absorbing system.

Implantable assemblies/devices and methods are provided for manipulating energy transferred by members defining an articulating anatomical joint, wherein the members collectively define a path of motion. Assemblies/devices are provided with a first component configured to be attached to a first anatomical member of the anatomical joint, a second component configured to be attached to a second anatomical member of the anatomical joint; and a tension member joining the first and second components. The tension member is placed under tension to absorb energy transferred by the anatomical members when the first component is attached to the first anatomical member and the second component is attached to the second anatomical member and a distance between locations of attachment of the first and second components becomes smaller then an implant-defined distance between the locations.

Implantable assemblies for manipulating energy transferred by members defining an anatomical joint, and methods of implanting and using. The members of the anatomical joint collectively define a path of motion. An assembly includes a first component configured to be attached to a first member of the anatomical joint; a second component configured to be attached to a second member of the anatomical joint; and a joint joining the first and second components. The first component includes a first flex member and the second component includes a second flex member. The first and second flex members are configured to flex to absorb energy transferred by the members of the anatomical joint.

An internal bracing system is disclosed for stabilizing a joint such as the knee, shoulder, ankle or the like. The internal bracing system includes an extra-articular tension band mechanism and an anchor assembly therefore. The internal bracing system adds substantial control to unstable joints which is effective in limiting the pathological joint motions and internal slippage. The anchor anchoring assembly designed to affix a tethering device to various bony structures which form a joint, for the purpose of providing stability. The anchor assembly includes an anchor and a set screw. A double helix thread/chamber structure between the anchor and set screw securely holds the tether without binding.

The present invention is related to hyaluronic acid compositions consisting in a binary mixtures of hyaluronic acid samples having mainly different weight-average molecular weight and then different rheological properties in aqueous solution. The resulting compositions have demonstrated peculiar rheological behaviour with a balance between viscosity and viscoelasticity. Accordingly, these compositions of hyaluronic acid are useful for treatment of joint diseases by intra-articular administration or extra-articular application in soft tissue disorders.

An isometer for determining isometric graft tunnel placement for lateral side surgical augmentation or reconstruction for anterolateral or posterior lateral rotary knee instability. This graft tunnel placement isometry assessment and measurement device is designed to be used with a graft and an extra-articular technique that restores rotatory, lateral, and anterior/posterior knee stability when used by itself or in combination with intra-articular ACL/PCL reconstruction. The isometer includes an elongated body with a slider rod that slides horizontally within the body and a cannulated fixed stylus attached transversely to the first end of the elongated body. Within that cannulated fixed stylus is a guide pin that slides freely but that can also be fixed using a fixed-stylus set screw. Similarly, a cannulated movable stylus is attached transversely to the first end of the slider rod, and within that cannulated movable stylus is a guide pin that slides freely but that can also be fixed using a movable-stylus set screw. There is a pointer encircling the slider rod that slides with the slider rod, but whose position along the slider rod can also be adjusted manually. The slider rod may also have a rotatable member that allows each end of the slider rod to rotate relative to the other end. The rotatable member obviates slider rod impingement during operation. To determine rotary knee isometry during knee reconstructive surgery, the guide pins are positioned over previously identified lateral reconstruction tunnel sites. The guide pins are then driven into the bone tunnel sites and the knee put through a full range of motion by flexing and extending the knee while the isometer position is maintained and the pointer movement is monitored. If movement of the pointer is unacceptably large, the guide pins are re-set, re-positioned and re-driven into different pre-identified lateral reconstruction tunnel sites, and pointer movement during full range motion is again monitored until movement is acceptably small.
