Description
Summary:Injectable implants constitute a newly developed treatment class in the battle against osteoarthritis. They consist of water-formulated supramolecular polymer, coming from a new class of resorbable biomedical materials, and are implanted in encapsulated joints in a liquid form, where they solidify to form a tough, elastic, and cushioning layer between the joint surfaces. To resort any effect, intra-articular delivery should be guaranteed, and the implant should be distributed throughout the entire joint space. Traditional implantation techniques do not seem to suffice for this new implant class, being either imprecise (traditional injection) or overly invasive (open procedures and traditional arthroscopic surgery). We describe a needle arthroscopic implantation technique to reap the benefits of both worlds, ensuring precise implant delivery while avoiding unnecessarily invasive procedures. This study depicts our needle arthroscopic technique for implantation of injectable implants in the ankle, first metatarsophalangeal joint, and first carpometacarpal joint.
