The OrthoSensor Load Sensor (LS) is made exclusively for use with the Stryker Orthopaedics Knee Trial for Triathlon system with special authorization from OrthoSensor. The device is approved for early validation testing only. Therefore, the information reported by the OrthoSensor System shall not be used to affect patient outcome. The Load Sensor measures the forces between the tibia and the femur. It wirelessly transmits measured force data to the Link Station positioned outside the sterile field. The Load Sensor replaces the standard trial tibial insert, it is provided sterile, for single patient use. A Shim Set is included for thickness adjustments. Additional Load Balancing System components include:
Link Station: The Link Station houses a computer and all peripheral equipment required to interpret and display the force data. The Link Station provides a graphical and numerical presentation of the forces in one or both of the knee compartments. Receiver: The Receiver is incorporated into the Link Station; it receives the wireless transmissions from the Load Sensor and communicates the data to the computer. Refer to the OrthoSensor Link Station Instructions for Use for additional details on these components. INDICATIONS INDICATIONS INDICATIONS INDICATIONS The OrthoSensor Load Balancing System (LBS) is a tool for the adjustment of the femoral knee implant to reduce instability from flexion gap asymmetry. CONTRAINDICATIONS CONTRAINDICATIONS CONTRAINDICATIONS CONTRAINDICATIONS Any active or suspected latent infection in or about the knee joint. Refer to Stryker Orthopaedics Triathlon Knee System IFU for additional contraindications. PRECAUTIONS PRECAUTIONS PRECAUTIONS PRECAUTIONS Read and follow instructions for proper use and interpretation of force data displayed. Strict adherence to the indications, contraindications, precautions and warnings for this product is essential. Refer to Stryker Orthopaedics Triathlon Knee System IFU for additional precautions. USER/PATIENT SAFETY USER/PATIENT SAFETY USER/PATIENT SAFETY USER/PATIENT SAFETY The Load Sensor and Shim Set are supplied as single-use sterile devices. If Load Sensor or Shim Set packaging are open or damaged, do not use and immediately return to OrthoSensor. Impact or excessive loading of the Load Sensor may result in a failure of the Load Sensor housing, exposing the patient to non-sterile and non-biocompatible internal components. Load Sensor and Shim Sets are single use only. Do not reuse or resterilze. Load range of the Load Sensor is 5 to 40 pounds per condyle. Maximum safe allowable load for the OrthoSensor Load Sensor is 70 lbs per condyle. Refer to the Device History File for Load Sensor accuracy data. Do not load the Load Sensor at its edges. 07562-X1 OrthoSensor, Inc 1560 Sawgrass Corporate Pkwy, 4th Floor Sunrise FL, 33326 www.orthosensor.com The Load Sensor contains non-sterile, non-medical grade internal components. If the Load Sensor housing is damaged or TM cracked during procedure, take appropriate steps to promote patient safety. Do not disassemble the Load Sensor. Do not use Load Sensor if it appears not to be functioning properly. Observe all warnings and alarms generated by the OrthoSensor Link Station. Do not subject Load Sensor or Shims to sudden impact. Federal law restricts this device to sale by or on the order of a licensed physician STRUCTIONS ININININSTRUCT IONS STRUCT STRUCT IONS IONS 1. Prior to start of procedure, turn Orthosensor Link Station on. Ensure that the station is plugged into a standard 110V outlet. Then locate the power button, which is located along the left lower rear side of the monitor and press the button. Upon startup, the system will upload to the main screen. 2. Determine specific size load sensor. Remove pouched shims and load sensor from the box and set atop of the shelf on the Orthosensor Link Station. DO NOT OPEN POUCH SEALS. 3. Record Load Sensor serial number (S/N) onto patient and hospital records as required. 4. To activate the Load Sensor:
Locate the magnet on the right rear side of the retractable keyboard / mouse tray. a. b. With the product still in the sealed pouches, place the center rear section of the device over the magnet; a red light will illuminate; continue to hold in place until the red light turns off. 5. Once the unit is activated, locate the TKA load balancing icon on the screen of the smart system and activate the software. 6. Upon activation of software scan the label barcode attached to the Load Sensor outer pouch. 7. The software will now enter the active display mode. 8. Open double sealed pouches per hospital protocol (Load Sensor and Shim Set). 9. If required, snap a shim onto the base of the Load Sensor before implanting into the Tibia tray. Shim size to be determined by the physician. a. To remove the shim or exchange for another size, simply unsnap the installed shim and replace. 10. The physician should manually compress / apply load to the device and verify its response on the Link Station screen prior to placing Load Sensor into the tibia tray. 11. Confirm that the load sensor module is fully seated when installed onto the tibial tray. 12. Flex the joint throughout its full range of motion five times (5X) to ensure appropriate response on the Link Station. 13. Perform knee surgery with the Load Sensor in conjunction with the instructions displayed on the Link Station, and per the requirements of the Stryker Orthopaedics Triathlon Knee System. Due to the early verification status of the Load Sensor do not use the data to affect patient outcome. The load range of the Load Sensor is 5 to 40 pounds per condyle. a. b. The maximum safe allowable load for the OrthoSensor Load Sensor is 70 lbs per condyle. 14. Dispose of Load Sensor per institutional guidelines for biohazardous medical waste.
