DCF SURGICAL TECHNIQUE (FEMORAL) GENUTECH

Product catalog summary
Surgical Approach
The procedure involves an anterior midline incision with internal parapatellar arthrotomy and external patellar dislocation, extending from the quadriceps tendon to the tibial tuberosity.
Surgical Sequence
The surgery can start with either tibial or femoral cuts. The sequence includes distal femoral cutting, anterior and posterior femoral cuttings, PS/NPS choice, intercondylar box cutting (if PS), trial femoral prosthesis placement, tibial cutting, checking flexion and extension spaces, tibial keel preparation, patella action, mobility and stability check with trial implants, and final prosthesis placement.
Femoral Time
  • Initial Perforation: Entry point is perforated using an awl or Ø 9 mm drill.
  • Insertion of Intramedullary Alignment Rod: The rod is inserted to the maximum insertion limit mark.
  • Adjustment of Distal Cutting Guide: Set to "0" for an 8 mm cut, adjustable from "-4" to "+8".
  • Varus-Valgus Alignment: Positioned parallel to the transepicondylar line.
  • Distal Cutting: Performed with optional tibial protection plate.
  • Measurement of Femoral Size and Outward Rotation: Measured with knee at 90 degrees, typically set at 3°.
Tibial Time
  • Level of Resection: Determined for tibial cutting.
  • Tibial Cutting: Prepares for prosthesis placement.
  • Spacers in Flexion and Extension: Used to check joint space.
  • Preparation of Tibial Keel: Ensures proper fit of the tibial component.
  • Checking with Trial Components: Ensures proper alignment and fit.
Patellar Time
  • Thickness Measurement: Ensures proper patellar component fit.
  • Patellar Cutting and Perforation: Prepares patella for prosthesis.
Final Implantation
Placement of the final prosthesis and optional use of Redon suction drains.
Annexes
Includes additional information on implants, instruments, and notes.
Installation of the “4-in-1” Cutting Block
Ensure distal contact and secure with side pins. Perform femoral cuts and bevels using the cutting block.
Removal of the Cutting Block
After femoral cuts, remove the pins and disimpact the cutting block using the integrated diapason hammer.
Implantation of the Trial Femoral Component
If preserving the posterior cruciate ligament (NPS), drill two holes with a 6 mm NPS drill bit. For a PS prosthesis, use the saw guide to recut the intercondyle.
Tibial Time
Instruments allow osteotomy with extramedullary or intramedullary guides. The tibial cutting template is mounted on the extramedullary rod, adjustable to the ankle. For intramedullary guidance, open the tibial canal with an awl and drill bit.
Level of Resection
Use the probe to determine the resection level. Fix the cutting guide to the tibia with headless pins and lock it with a 2.5 mm hexagonal driver.
Tibial Cutting
With the guide fixed, perform the osteotomy of the tibial epiphyseal area. Use 1.3 mm thick saw blades to avoid improper cuts.
Spacers in Flexion and Extension
Insert spacers to evaluate limb alignment and ligament tension. If excessive strain is observed, refer to Annex 3 for recuts.
Preparation of the Tibial Keel
With the trial femoral component installed, adjust the tibial tray rotation and check flexion-extension behavior. Mark the rotation position for later reference.
Checking with Trial Components
With trial components installed, verify knee mobility and stability. Adjust the central cylinder size for the tibial tray cup, considering standard or long options.
Patellar Set Overview
1. Patellar Time and Thickness Measurement
Maintain a minimum bone thickness of 12-14 mm to prevent fractures. The height of the prosthetic patella should not exceed the original to avoid excess pressure. Consider both the diameter and the height of the patellar component.
2. Patellar Cutting and Perforation
Remove osteophytes and synovial tissue to expose tendons. Use the patellar resection clamp to make the cut, ensuring the anterior cortex rests on the bolts. The perforation for the prosthetic pivot is slightly medialized. If increased tension is observed with the trial patella, a smaller component may be chosen.
3. Final Implantation
After verifying the trial components, replace them with the final prostheses. Fix the tibial insert by screwing the anterior bolt to the tibial tray.
Annexes
Annex 1: Whiteside’s Line
Used for positioning the gauge when hypoplasia is noted in posterior condyles.
Annex 2: Femoral Component Placement
Recommends using an impactor/extractor for proper placement and fixation.
Annex 3: Recuts
Guidelines for additional cuts if spacers do not fit properly in flexion or extension.
Annex 4: Tibial Inserts
Instructions for clipping and removing tibial inserts.
Annex 5: Patellar Compression Clamp
Designed to maintain pressure during cement curing for patella fixation.
Annex 6 & 7: Tools and Protection
Details on tools like the Hudson-Jacobs hybrid terminal and tibial protection plate.
Overview: The document provides detailed specifications and references for various orthopedic components and instruments used in knee surgeries. It includes both cemented and cementless femoral components, tibial inserts, tibial trays, patellar components, and a comprehensive list of surgical instruments.
Femoral Components: Lists both PS (Posterior Stabilized) and NPS (Non-Posterior Stabilized) femoral components available in cemented and cementless versions. Each component is specified by size and reference number, with options for left and right configurations. Cementless components are manufactured on order.
Tibial Inserts and Trays: Tibial inserts are available in both NPS and PS versions, with sizes ranging from 10 mm to 20 mm in length. The tibial trays are listed by size, and fixation bolts and caps for the trays are also specified.
Patellar Components: Available in diameters ranging from 32 mm to 40 mm, with each size having a specific reference number.
Instruments: Details various surgical instruments organized into sets for femoral, tibial, and patellar procedures. Each instrument is listed with its reference number and specific function, such as cutting guides, alignment rods, impactors, and chisels. The instruments are available in sets that include trays for organization and sterilization.
Trial Components: Trial components for femoral, tibial, and patellar parts are listed, allowing for pre-surgical fitting and assessment. These are specified by size and reference number.
Key Notes: Some components and instruments are available with sealed containers to maintain sterilization. The document emphasizes contacting Surgival for components manufactured on order.
