A method for treating arthritis of a joint includes identifying a bone lesion in a bone adjacent to the joint; and implanting in the bone a reinforcing member in or adjacent to the bone lesion. A kit for conducting the method includes: (a) at least one reinforcing member having a proximal face adapted to face the joint, a distal face adapted to face away from the joint, and a wedge-shaped edge adapted to pierce bone, wherein the at least one reinforcing member is planar and sterile; and (b) a container adapted to maintain the at least one reinforcing member sterile. Another kit includes: (a) a sterile fluid; (b) a syringe for injecting the fluid into a bone; (c) a curing agent adapted to cure the fluid to polymerize and/or cross-link; and (d) a container adapted to maintain the sterility of contents of the container.

Osteoarthritis treatment and device

A method, apparatus, and system for cutting anatomic members, such as ligaments, in surgical procedures such as carpal tunnel release, plantar fasciotomy, gastroc release, and cubital and tarsal tunnel release. The apparatus includes a guide tool for guiding a knife and a scope during surgery which may be employed with a translating knife. Relevant features include a knife stop for preventing the knife from inadvertently raising out of the knife channel, indicia viewable to show the proper orientation for the guide tool, a self dilating tip and channel design on the guide tool, a cover piece and/or pivotable panel system for preventing ligaments and other anatomy from getting caught in the guide tool, a pivot pin and groove system for stabilizing the knife and also assuring that the knife blade is not inadvertently raised out of the channel, and a use indicator employable to prevent re-use of the device.

Method and apparatus for endoscopic ligament release

The embodiments provide provides devices, instruments, and associated methods for treating joint pain. A joint is evaluated using magnetic resonance imaging to detect any defects in the subchondral bone. For example, using T2-weighted MRI images, bone marrow lesions or edemas can be identified, and using T1-weighted MRI images, associated regions of sclerotic bone adjacent to the bone marrow lesion can be identified. The treatment method may involve introducing a bone void filler material at the site to address the bone marrow lesion or edema, and/or drilling and inserting an implant to address the sclerotic bone, bone marrow lesion or edema, and insufficiency or stress fractures. An access path is mapped to a location in the subchondral region where the insufficiency fracture resides. The access path attempts to preserve an articular surface of the joint. A reinforcing member that stabilizes the insufficiency fracture is then implanted via the access path.

Method for treating joint pain and associated instruments

Methods for the prevention, or delayed onset or progression of, bone marrow edema or bone marrow lesion, and subchondral treatment to prevent the progression of osteoarthritis of a joint are disclosed. The methods involve treating the subchondral bone, while preserving, as much as possible, the joint's articular and cartilage surface. The methods could be performed before, during, or after an initial arthroscopic surgery to repair the joint. Associated devices and instruments for treatment of the subchondral bone are also disclosed.

Methods for altering the natural history of degenerative disc disease and osteoarthritis of the spine are proposed. The methods focus on the prevention, or delayed onset or progression of, subchondral defects such as bone marrow edema or bone marrow lesion, and subchondral treatment to prevent the progression of osteoarthritis or degenerative disc disease in the spine and thereby treat pain.

Subchondral treatment of joint pain of the spine

Methods for the prevention, or delayed onset or progression of, bone marrow edema or bone marrow lesion, and subchondral treatment to prevail the progression of osteoarthritis of a joint are disclosed. The methods involve treating the subchondral bone, while preserving, as much as possible, the joint's articular and cartilage surface. The methods could be performed before, during, or after an initial arthroscopic surgery to repair the joint. Associated devices and instruments for treatment of the subchondral bone are also disclosed.
