Read the full statement (264 words)
The REMEDY Stemmed Knee Spacer, which consists of 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 where gentamicin is the most appropriate antibiotic based on the susceptibility of the infecting micro-organism(s).
The REMEDY Stemmed Femoral Component can be used with a PMMA Tibial Component or an All-Poly tibial component. The device is applied on the femoral condyles (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). Stem Extensions may be used with the Femoral and Tibial components. Moreover, if necessary, the Tibial Component could be coupled with the REMEDY Tibial Insert Wedge when a large tibial defect is present.
The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection). The device is intended for use with antibiotic (gentamicin) bone cement.
The REMEDY Stemmed 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, 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.
Indications for use as stated in the FDA summary.
