This disclosure is directed to a resilient interpositional arthroplasty implant. Such implants function to pad cartilage defects, cushion, and replace or restore the articular surface, which may preserve joint integrity, reduce pain and improve function. The implant may endure variable joint compressive and shear forces and cyclic loads. The implant may repair, reconstruct, and regenerate joint anatomy, and thereby improve upon joint replacement alternatives. The walls of this invention may capture, distribute and hold living cells until aggregation and hyaline cartilage regrowth occurs. The implant may be deployed into debrided joint spaces, molding and conforming to surrounding structures with sufficient stability so as to enable immediate limb use after outpatient surgery. Appendages of the implant may repair or reconstruct tendons or ligaments, and menisci by interpositional inflatable or compliant polymer arthroplasties that promote anatomic joint motion.

Devices and methods are disclosed for joint replacement.

A subtalar implant for arthroereisis of the talocalcaneal joint. The implant being intended to be inserted into the talocalcaneal joint via its lateral orifice and having an oblong shape that extends longitudinally along an axis of insertion of the implant. The implant includes: a head with the shape of a cone of revolution centred on the axis of insertion; an anchoring thread; and a rod having the shape of a cylinder of revolution. The rod has, on its surface, the anchoring thread and being intended to be inserted up to the axis of rotation of the talocalcaneal joint. The head has, on its radially outer surface, a retaining element for retaining the implant in rotation about the axis of insertion, the retaining element being exerting retention against a colonising tissue.

Innovative orthopedic implant assemblies and devices are provided. One example assembly may include two implant devices. An example implant device may include two ends oppositely located with a bulbous portion at one end. An example bulbous portion may include a crown defining a terminal axis of one end and a thread disposed on an exterior surface of the bulbous portion and originating at the crown. A threaded portion defining a second terminal axis may be located at another end. An example second implant device may include two ends oppositely located, a looped portion defining an aperture at one end and including an interior surface with a groove disposed therein, and a threaded portion defining a terminal axis at another end. The thread and the groove can lock the bulbous portion and the looped portion when engaged with one another.

Medical constructs with twisted cables formed from a plurality of collagen fibers twisted together to form strands and those strands twisted together to form cables and relate methods of twisting the collagen fibers to form the medical constructs while holding the fibers and strands of fibers in tension and twisting in a first direction (i.e., in a clockwise direction), then twisting them in a second opposing (counterclockwise) direction for a number of twists per inch.

Methods for temporarily fixing an orientation of a bone or bones. Methods of correcting a bunion deformity. Bone positioning devices. Methods of using a bone positioning device. Bone preparation guides. Methods of using a bone preparation guide.

An implant system for implantation at a joint, the implant system including an implant device, the implant device comprising a body portion having first and second ends, and a first elongate member, extending from the first or second end of the body portion, the implant system further comprising a corresponding fixation device for securing the first elongate member to a subject, the fixation device comprising at least one latching element, the first elongate member comprising at least one cooperating element, the at least one cooperating element being capable of cooperating with said at least one latching element of the fixation device in use.

A mold adapted to be introduced into a joint of a human patient for resurfacing at least one carrying contacting surface of said joint is provided. The mold is adapted to receive material for resurfacing at least one carrying contacting surface of said joint. The mold is further adapted to be resorbed by the human body or melt after having served its purpose. Further, a method of treating hip joint osteoarthritis in a human patient by providing an artificial hip joint surface using a mold is provided. The method comprises the steps of: said mold being placed inside of said hip joint, said mold being injected with a fluid adapted to harden, said fluid hardening inside of said hip joint, said mold being resorbed by the human body, and said hardened fluid serving as artificial hip joint surface.

The disclosure is directed to a resilient implant for implantation into human or animal joints to act as a cushion allowing for renewed joint motion. The implant endures variable joint forces and cyclic loads while reducing pain and improving function after injury or disease to repair, reconstruct, and regenerate joint integrity. The implant is deployed in a prepared debrided joint space, secured to at least one of the joint bones and expanded in the space, molding to surrounding structures with sufficient stability to avoid extrusion or dislocation. The implant has opposing walls that move in varied directions, and an inner space filled with suitable filler to accommodate motions which mimic or approximate normal joint motion. The implant pads the damaged joint surfaces, restores cushioning immediately and may be employed to restore cartilage to normal by delivering regenerative cells.

A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores stress distribution, stability, and function to the knee joint after removal of the damaged natural meniscus. In some embodiments, the prosthetic device includes an anti-migration feature that inhibits extreme movement within the joint while permitting free floating over a significant range. In one aspect, the anti-migration feature is an enlarged anterior structure or a posterior meniscus remnant engaging channel while in another aspect, the anti-migration feature includes a tethering member. Still further, removable radiopaque features are provided to enhance trialing of the implant prior to final implantation within the joint.
