Intended Use

The StageOne Knee Cement Spacer Molds are intended to create a temporary knee replacement prosthesis as part of a two-stage revision procedure.

Device Story

Sterile, single-use silicone molds; used by surgeons in clinical settings to create temporary tibial and femoral knee implants. Surgeon fills molds with Refobacin® Bone Cement R; cured cement spacers inserted into tibiofemoral joint space after debridement and removal of failed implants. Serves as temporary prosthesis during two-stage revision for infection; maintains joint space and delivers local antibiotic therapy. Patient must use mobility aids due to mechanical limitations of bone cement. Spacers explanted within 180 days for permanent implant placement.

Clinical Evidence

No clinical data provided. Substantial equivalence established via non-clinical bench testing, including biocompatibility, packaging, sterilization validation, wear testing, and antibiotic elution testing.

Technological Characteristics

Silicone molds; single-use; sterile. Designed for manual molding of PMMA bone cement (Refobacin® Bone Cement R). Same design, variants, sizes, and sterilization method as predicate. Double sterile barrier packaging.

Indications for Use

Indicated for skeletally mature patients undergoing two-stage revision TKR due to septic process. Requires use with Refobacin® Bone Cement R, systemic antimicrobial therapy, and mandatory use of mobility aids (crutches/walkers). Temporary prosthesis must be explanted within 180 days.

DEPARTMENT OF HEALTH AND HUMAN SERVICES Food and Drug Administration # Indications for Use 510(k) Number (if known) K213287 #### Device Name StageOne™ Knee Cement Spacer Molds #### Indications for Use (Describe) StageOne™ Knee Cement Spacer Molds are indicated for use to mold a temporary total knee replacement (TKR) for skeletally mature patients undergoing a two-stage revision procedure due to a septic process. The temporary prosthesis is molded using Refobacin® Bone Cement R and inserted into the joint space following removal of the existing total knee replacement implants and debridement. The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection). The knee prosthesis made from the StageOne™ Knee Cement Spacer Molds is not intended for use more than 180 days, at which time it must be explanted and permanent devices implanted or another appropriate treatment (e.g. resection arthroplasty, fusion, etc.). Due to the inherent mechanical limitations of the knee prosthesis material (Refobacin® Bone Cement R), the temporary knee prosthesis is only indicated for patients who will consistently use traditional mobility devices (e.g. crutches, walkers) throughout the implant period.

The subject device is a sterile, single use device made of silicone and is used to create temporary tibial and femoral implant components made from antibiotic bone cement, Refobacin® Bone Cement R. After removal of the initial implant the prepared cement spacers are placed into the tibiofemoral joint space using Refobacin® Bone Cement R as the first stage of a two-stage revision surgical procedure. The temporary spacers remain in place (180 days or less) until the second stage of the two-stage revision procedure is performed to implant a conventional knee joint prosthesis. | | Intended Use: | The StageOne Knee Cement Spacer Molds are intended to create a temporary knee replacement prosthesis as part of a two-stage revision procedure. | | Indications for Use: | StageOne™ Knee Cement Spacer Molds are indicated for use to mold a temporary total knee replacement (TKR) for skeletally mature patients undergoing a two-stage revision procedure due to a septic process. The temporary prosthesis is molded using Refobacin® Bone Cement R and inserted into the joint space following removal of the existing total knee replacement implants and debridement. The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection). | | | The knee prosthesis made from the StageOne™ Knee Cement Spacer Molds is not intended for use more than 180 days, at which time it must be explanted and permanent devices implanted or another appropriate treatment performed (e.g. resection arthroplasty, fusion, etc.). | | | Due to the inherent mechanical limitations of the knee prosthesis material (Refobacin® Bone Cement R), the temporary knee prosthesis is only indicated for patients who will consistently use traditional mobility devices (e.g. crutches, walkers) throughout the implant period. | | Summary of Technological Characteristics: | The rationale for substantial equivalence is based on consideration of the following characteristics: ● Intended Use: Identical to the predicate device. ● Indications for Use: The subject device has similar indications for use as the predicate device. The subject device is now indicated for use only with Refobacin® Bone Cement R. There are no changes to the intended clinical use of the device. ● Materials: The subject device is made of the same raw materials as the predicate device. ● Design Features: The subject device has the same design features as the predicate device. ● Variants/Sizes: The subject device has the same variants and sizes as the predicate device. ● Sterilization Method: The subject device is sterilized using the same sterilization method as the predicate device. ● Manufacturing Process: The subject device is manufactured using a manufacturing process similar to the predicate device. ● Packaging: The subject device has similar packaging as the predicate device; both the subject and predicate devices are packaged in a double sterile barrier configuration. | {4}------------------------------------------------ {5}------------------------------------------------ ### Summary of Performance Data (Nonclinical and/or Clinical): ● Non-Clinical Testing: Nonclinical performance testing was conducted to support the proposed modifications for the subject StageOne™ Knee Cement Spacer Molds and establish substantial equivalence between the subject device and identified predicate device. - Biocompatibility Evaluation o - Packaging testing O - Sterilization Validation O - Wear testing O - Antibiotic elution testing O - Clinical Testing: Clinical data was not required to establish ● substantial equivalence between the subject StageOne Knee Cement Spacer Molds and the identified predicate device for the proposed device modifications. The subject device has the same intended use, similar clinical indications for use as the predicate device.
