The Remedy Knee Spacer, which consists of a Femoral Component and a Tibial Insert, is indicated for temporary use (maximum 180 days) as an adjunct to total knee replacement (TKR) in skeletally mature patients undergoing a two-stage procedure due to a septic process and where gentamicin is the most appropriate antibiotic based on the susceptibility pattern of the infecting micro-organism(s). The device is applied on the femoral component) and on the tibial plate (tibial component) following removal of the existing implant and radical debridement. The use of the Tibial Insert is optional, when a large tibial defect is present. The device is intended for use in conjunction with systemic antibiotic therapy (standard treatment approach to an infection). The Remedy Knee Spacer is not intended for use for more than 180 days, at which time it must be explanted and a permanent device implanted or another appropriate treatment performed (e.g. resection arthroplasty, fusion etc.). Because of the inherent mechanical limitations of the device materials (gentamicin/polymethylmethacrylate), the device is only indicated for patients who will consistently use traditional mobility assist devices (e.g., crutches, walkers, canes) throughout the implantation period. The Remedy Stemmed Knee Spacer, which consists of a modular femoral, tibial and stem extension components, is indicated for temporary use (maximum 180 days) as an adjunct to total knee replacement (TKR) in skeletally mature patients undergoing a two-stage procedure due to a septic process and where gentamicin is the most appropriate antibiotic based on the susceptibility pattern of the infecting micro-organism(s). The device is applied on the femoral component) and on the tibial plate (tibial component) following removal of the existing implant and radical debridement. The use of the stem extension component is optional to replace the space occupied by the previous femoral and/or tibial stem (dead space management). Moreover, if necessary, the tibial component could be coupled with the Osteoremedies Remedy Tibial Insert Wedge when a large tibial defect is present. The device is intended for use in conjunction with systemic antibiotic therapy (standard treatment approach to an infection). The Remedy Stemmed Knee Spacer is not intended for use tor more than 180 days, at which time it must be explanted and a permanent device implanted or another appropriate treatment performed (e.g. resection arthroplasty, fusion etc.). Because of the inherent mechanical limitations of the device materials (gentamicin/polymethylmethacrylate), the device is only indicated for patients who will consistently use traditional mobility assist devices (e.g., crutches, walkers, canes) throughout the implantation period, allowing basic joint mobility.

The Remedy® Knee Spacer, cleared via K112470, is a temporary knee spacer device consisting of independent components (femoral component, tibial component and insert wedge) that can be combined one with each other depending on the anatomy of the patient. The cleared femoral components are available in three sizes (54mm, 64mm and 74mm). With this 510(k) submission. OsteoRemedies is adding the additional 84mm size (extra-large) to the FDA cleared range of Remedy Femoral Component. The Remedy® Stemmed Knee Spacer is a temporary knee spacer device consisting of independent components (femoral component, tibial component and stem extension components) that can be combined one with each other depending on the anatomy of the patient. These components are available in different sizes to further accommodate variations in patient anatomy. The Stem Extension Implant components can be coupled with both the femoral and the tibial components, as they are intended to be used, if necessary, to replace the space occupied by the previous femoral and/or tibial stem. The Remedy Stemmed Tibial component could also be coupled, if necessary, with the commercially marketed Remedy Tibial Insert Wedge (K112470), when a large tibial defect is present. The Remedy Femoral Component 84mm and the Remedy Stemmed Knee Spacer are sterile, single-use devices intended for temporary use (maximum 180 days) as joint replacement. The devices are made of fully formed polymethylmethacrylate (PMMA), which is radio-opaque and contains gentamicin. The mass used to fill the molds (the unformed PMMA resin) is prepared from powder and liquid components. The liquid component consists of methylmethacrylate (MMA), N. N dimethyl-p-toluidine and hydroguinone; the powder component consists of PMMA, barium sulphate, benzovl peroxide and gentamicin sulphate. The stem components also present an inner core of Stainless Steel (AISI 316 ESR). The devices (which consists of the combination of single components) provide patients a temporary complete knee implant that allows for a natural range of motion and partial weightbearing during treatment of the infection, and preserves the soft tissue to prevent further complications, such as muscular contraction, to facilitate the subsequent joint replacement procedure after systemic treatment of the underlying infection. The devices are protected from bacterial adhesion due to the presence of gentamicin, similar to other spacers devices made with PMMA with antibiotics currently on the US market.

The REMEDY® Acetabular Cup 46mm ID/54mm OD consists of an acetabular cup that is indicated for temporary use (maximum 180 days) as an adjunct to total hip replacement (THR) in skeletally mature patients undergoing a two-stage procedure due to a septic process, and where gentamicin is the most appropriate antibiotic based on the susceptibility pattern of the infecting micro-organism(s). The REMEDY® Acetabular Cup 46mm ID/54mm OD is positioned into the acetabular cavity following removal of the existing acetabular and femoral components and radical debridement. The device must be combined with REMEDY® Hip Spacer using REMEDY® Modular Head 46 mm. The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection). The REMEDY® Acetabular Cup 46mm ID/54mm OD is not intended for use for more than 180 days, at which time it must be explanted and a permanent device implanted or another appropriate treatment performed (e.g. resection arthroplasty, etc.).

The Remedy® Acetabular Cup is a temporary spacer device available in a single size, intended to be combined with Remedy Hip Spacer using Remedy® Modular Head 46 mm. The Remedy® Acetabular Cup is sterile, single-use device intended for temporary use (maximum 180 days) as joint replacement. The device is made of fully formed polymethylmethacrylate (PMMA), which is radio-opaque and contains gentamicin.
