Abstract: Exemplary embodiments are directed to instruments, methods and systems for harvesting and implanting graft materials, including instruments for capturing a surface topography of an anatomical location, instruments for defining an implant region, and graft harvesting devices. Exemplary embodiments are also directed to methods for capturing a surface topography of an anatomical location, methods for defining an implant region, and methods for harvesting a donor plug. The exemplary instruments, methods and systems generally include capturing a surface topography of a defect region, creating a defect region cavity, and harvesting a donor plug configured and dimensioned to be implanted in the defect region cavity.

Abstract: The present disclosure provides instruments and systems for accessing and removing hyaline cartilage from desired donor sites. The present disclosure also provides instruments/systems for implantation of hyaline cartilage grafts, e.g., to fill osteochondral defects. The apparatus/systems may be used in connection with mapping techniques and systems. Thus, in exemplary embodiments of the present disclosure, a clinician may be guided in his use of the disclosed apparatus/systems by articular joint surface mapping data in locating/identifying harvest sites for “best fit” grafts, i.e., grafts that exhibit desired geometric and/or surface attributes for use in particular implantation site(s). Alternatively, the disclosed instruments/systems may be employed to access anatomical sites independent of such mapping techniques/systems.

Abstract: Tools and instruments for use in orthopedic applications for forming openings and/or cavities in anatomical structures, e.g., bone and cartilage structures, are provided. The tools/instruments include a shaft having a distal end and defining a longitudinal axis and a shank disposed at the distal end of the shaft. The shank includes a tapered cutting edge and an adjacent fluted region. The shank is effective to collect and deposit materials generated by a cutting action within an opening or cavity formed thereby. A stop may be mounted with respect to the shaft. The tools/instruments deliver a clean and crisp cut to anatomical structures, thereby facilitating interaction with subsequently delivered plugs and/or implants.

Abstract: An activity knee brace is disclosed in which the structural hinge axis of the brace moves to overlie the changing center of pivot of the condyle of the femur with respect to the plateau of the fibula-tibia. The brace consists of a thigh portion, a lower leg portion, and a structural hinge axis therebetween. The thigh portion supports the brace in the thigh; the lower leg portion supports the brace to the lower leg. The thigh portion is braced at the lower end at the medial supracondylar area by lateral and medial condylar pads in conjunction with an adjustable strap system. Provision is made to differentially adjust the lateral and medial condylar pads towards one another over the supracondylar hollow to affix and track the relative movement of the supracondylar hollow of the femur relative to the plateau of the fibula tibia. A pivot for the lateral and medial condylar pads is provided off axis with respect to the structural hinge of the brace.

Abstract: A malleable, handed, wrist brace extending between the forearm and hand for immobilizing the wrist is disclosed. The brace includes a bendable and cut work hardened aluminum sheet cut with a central volar extension ending in a palmar support. The volar extension includes paired transversely extending forearm gripping arms and paired transversely extending wrist joint gripping arms. At the hand end of the brace, paired transversely extending palm gripping arms extend to opposite sides of the palm from just above the palmar support. The cut aluminum sheet has a molded exterior and liner interior bonded to opposite side with the gripper arms bent to confront the liner to the limb to be immobilized. The palmar support portion of the brace confronts a convex portion of the palmar support to the palm to provide preferred anatomical positioning of the hand with respect to the forearm (roughly 5.degree. of dorsi-flexion at the wrist).

Abstract: An activity knee brace is disclosed in which the hinge axis of the brace articulates to overlie during knee flexure the moving center of pivot of the condylar of the femur with respect to the plateau of the fibula tibia. The brace consists of a thigh portion, a lower leg portion, and a hinge axis therebetween. The thigh portion supports the brace in the thigh. The lower leg portion supports the brace to the lower leg. The hinge axis is designed to overlie the point of pivot of the knee. Articulating of the activity brace hinge axis occurs from the thigh portion. The thigh portion is braced at the upper end to the thigh. The thigh portion is braced at the lower end at the medial supracondylar area by pad and adjustable strap system contacting and locating on the supracondylar hollow on the inside of the upper leg. The pads at the lower thigh portion of the brace are mounted at a pivotal axis. This pivotal axis is offset with respect to the hinge axis at a distance approximately 11/8 th inches.

Abstract: An orthopedic rehabilitation knee brace having paired labeled hinges on either side of a braced knee is provided with easily set flexion and extension limits of movement for providing to the braced leg limited post-operative or recovery restraint of the knee. Each brace includes two improved circular hinge elements with a first group of easily set stops for producing restraint in flexion and a second group of easily set stops for producing restraint in extension of the knee. Extending upwardly and downwardly from each circular hinge housing on both sides of the brace are telescoping respective upper and lower leg wings for effecting from the hinge desired restricted movement of the leg member at the knee joint. The discrete flexion and extension stops extend radially of the hinge and are normally in the disengaged position. Each of the individual stops is exposed through the outward portion of the hinge for manipulation at attached stop operating points.

Abstract: A motion limiter (2) for use with a short leg walker (4) includes a threaded shaft (20) passing freely through a hole (42) in a sliding block or guide (36) that is pivotally attached preferably to an upper part (6) of the walker. The lower end (28) of the shaft is preferably pivotally mounted in a recess (34) in the lower portion (10) of the walker and the remainder of the shaft is free to slide within the hole in the sliding block within a recess (26) in the upper part of the walker. The position of stop members (64, 68), threaded to the shaft above and below the block, determine the amount or fraction of the shaft permitted to pass through the hole in the sliding block. As the stop members are positioned along the shaft relatively far apart from one another, a greater length of the threaded shaft is permitted to pass through the sliding block, thereby increasing the range of motion of the walker. Conversely, as the stop members are moved relatively closer together, the range of motion decreases.

Abstract: The disclosed invention is an improved semi-rigid, ankle support generally conforming to the instep, ankle, and lower leg, and wearable inside a shoe, said support being comprised of one or more non-elastic panels and one or more elastic panels extending at least part of the length of said support, whereby the ankle is largely supported and immobilized, yet the support conforms to the foot, ankle, and lower leg and does not significantly reduce ankle function.Preferably, the support is comprised of a largely sock-shaped unit closable at the front, defining apertures through which the heel and the toes extend, and sometimes including stays to improve the support given the ankle. This unit is formed of panels of non-elastic material and at least one panel of elastic material, preferably three such elastic panels.
