as well as elements of scarring, which may decrease soft tissue mobility. If a high tibial osteotomy has been performed previously, a more traditional exposure is recommended, as this may require reconstructive methods which may be different from primary total knee replacement.

This Premier™ Total Knee Instrumentation surgical technique is utilized by Keith Berend, M.D., Biomet as the manufacturer of this device, does not practice medicine and does not recommend this device or technique. Each surgeon is responsible for determining the appropriate device and technique to utilize on each individual patient.

PREMIER™ TOTAL KNEE INSTRUMENTATION Preoperative Planning

€ PREOPERATIVE PLANNING In order to assess bone stock, potential ligament instability and the anatomical axis, a 36” long standing A/P X-ray is recommended. Determine the angle between the anatomic and mechanical axis, assuring the distal femoral cut is perpendicular to the mechanical axis (Figure 1). Estimate femoral component size preoperatively by using lateral view X-rays and radiographic templates. Confirmation

of

the

appropriate

size

component

intraoperatively is critical for normal kinematics.

PREMIER™ TOTAL KNEE INSTRUMENTATION Surgical Technique 5

PREMIER™ TOTAL KNEE INSTRUMENTATION Approaches

€ APPROACHES Premier™ Total Knee Instruments are designed for use with both traditional surgical methods as well as minimally invasive techniques. Three basic procedures can be utilized for total knee arthroplasty: •

Option 1: Mini-medial Parapatellar (See page 4 for surgical technique)

•

Option 2: Mid-vastus (See page 5 for surgical technique)

•

Option 3: Sub-vastus (See page 7 for surgical technique)

The mini-medial parapatellar approach may be used initially. This approach can be easily extended or converted to a more extensive traditional approach, should additional exposure be necessary. The mid-vastus approach can create extensive exposure without violating the quadriceps tendon with only a small split in the vastus medialis obliquus (VMO) muscle. The sub-vastus approach preserves the quadriceps muscle and tendon, but requires careful assessment of patellar mobility as well as size and bulk of the quadriceps muscle mass.

6 Surgical Technique PREMIER™ TOTAL KNEE INSTRUMENTATION

PREMIER™ TOTAL KNEE INSTRUMENTATION Mini-medial Parapatellar Approach, Option 1

€ MINI-MEDIAL PARAPATELLAR APPROACH, OPTION 1

INITIAL SKIN INCISION Make the skin incision centered over the medial one-third of the patella extending from 1cm above the superior pole of the patella to the tibial tubercle. The length of this incision will vary depending on the anatomy, but generally range between 4–6.” It is recommended to perform the skin incision in a flexed position which will help minimize the sensitivity with kneeling. It is extremely important to monitor the proximal and distal margins of the incision in order to make certain there is not increased tension from excessive retraction. Extension of the skin incision may be necessary during the procedure depending on the anatomy and the quality of the soft tissue. Keep in mind that the priority is to minimize the soft tissue trauma and to preserve the quadriceps muscle.

APPROACH Make a mini-medial parapatellar arthrotomy, beginning at Figure 2

the top medial corner of the patella and continuing down along the patellar tendon, ending at the patellar tendon insertion (Figure 2). Once the incision has been made, ensure the release of any soft tissue adhesions.

DEEP EXPOSURE With the knee in the extended position, perform the arthrotomy from 1–2cm above the superior pole of the patella, extending to the level of the tibial tubercle. Perform fat pad excision to facilitate exposure and to improve patellar mobility. Perform a medial release at this time to only release what is necessary for the existing deformity. This will also allow for easy placement of the medial retractors for protection of the medial collateral ligament as well as exposure of the proximal tibia later in the procedure.

PREMIER™ TOTAL KNEE INSTRUMENTATION Surgical Technique 7

PREMIER™ TOTAL KNEE INSTRUMENTATION Mid-vastus Approach, Option 2 Note: Because the patella is not everted in this technique, the patellar tendon may be tight and thus require greater retractor tension. Take special care not to violate the patellar tendon insertion point. A small-headed pin, suture or staple may be placed at the patellar tendon insertion to prevent avulsion.

MID-VASTUS APPROACH, OPTION 2

INITIAL SKIN INCISION Make the skin incision centered over the medial onethird of the patella extending from 1cm above the superior pole of the patella to the tibial tubercle (Figure 3). The length of this incision will vary depending on the anatomy, but generally range between 4–6.” It is recommended to perform the skin incision in a flexed position which will help minimize the sensitivity with kneeling. It is extremely important to monitor the proximal and distal margins of the incision in order to make certain there is not increased tension from excessive retraction. Extension of the skin incision may be necessary during the procedure depending Figure 3

on the anatomy and the quality of the soft tissue. Keep in mind that the priority is to minimize the soft tissue trauma and to preserve the quadriceps muscle.

8 Surgical Technique PREMIER™ TOTAL KNEE INSTRUMENTATION

PREMIER™ TOTAL KNEE INSTRUMENTATION Mid-vastus Approach, Option 2

APPROACH Extend the capsular incision in a straight line proximally obliquely cutting across VMO muscle fibers. This is most easily performed with the knee flexed near 90 degrees. The VMO incision typically extends for a distance of 1–3cm. This length is partially dependent on the VMO insertion site onto the patella. If the VMO has a proximal patellar insertion, the VMO incision may be only 1–2cm. If the VMO inserts into the patella as far distally as midpatella, the incision into the VMO may reach 3–4cm. If it is later determined that a more extensile incision is required for proper exposure, the VMO incision can be continued straight proximally. Note: The strongest fascia for closure is on the deep surface of the VMO. When the capsule is closed, this deep fascial layer must be included in the sutures. Typically only two or three sutures are required to close the mid-vastus VMO extension of the capsular incision. Once the incision has been made, ensure the release of any soft tissue adhesions.

DEEP EXPOSURE With the knee in the extended position, perform the arthrotomy from 1–2cm above the superior pole of the patella, extending to the level of the tibial tubercle. Perform fat pad excision to facilitate exposure and to improve patellar mobility. Perform a medial release at this time to only release what is necessary for the existing deformity. This will also allow for easy placement of the medial retractors for protection of the medial collateral ligament as well as exposure of the proximal tibia later in the procedure. Note: Because the patella is not everted in this technique, the patellar tendon may be tight and thus require greater retractor tension. Take special care not to violate the patellar tendon insertion point. A small-headed pin, suture or staple may be placed at the patellar tendon insertion to prevent avulsion.

Extension of the skin incision may be necessary during the procedure depending on the anatomy and the quality of the soft tissue. Keep in mind that the priority is to minimize the soft tissue trauma and to preserve the quadriceps muscle.

APPROACH Figure 4

Make a horizontal arthrotomy along the inferior border of the VMO leaving a cuff of retinaculum for closure (Figure 4). Complete the arthrotomy in a standard manner along the medial patellar tendon. Once the incision has been made, ensure the release of any soft tissue adhesions.

PREMIER™ TOTAL KNEE INSTRUMENTATION Distal Femoral Resection

€ DISTAL FEMORAL RESECTION Utilize the .375” intramedullary (IM) drill to penetrate the femoral canal to a depth of approximately 1.5 to 2” (3.5 to 5cm). Place the canal entry location 1cm above the insertion of the posterior cruciate ligament and slightly medial in the intercondylar notch (Figure 5).

INTRAMEDULLARY ADJUSTABLE RESECTION GUIDE, OPTION 1

DISTAL

Set the adjustable distal femoral resection guide to the desired valgus angle by pressing and turning the valgus angle dial. A valgus angle setting of 0 to 9 degrees is available. Select the depth of distal resection by turning the resection level dial. The distal resection depth can range from a simple 1mm clean-up cut for revision scenarios up to 11mm for severe flexion contractures (Figure 6). Figure 5

Note: The standard distal resection is 9mm, matching the distal thickness of the Vanguard® implant.

Figure 6

PREMIER™ TOTAL KNEE INSTRUMENTATION Distal Femoral Resection

Assemble the IM rod and adjustable distal resection guide by inserting the IM rod through the central hole of the resection guide. Slowly introduce the IM rod to the femoral canal to depressurize the canal. Slide the adjustable resection guide until it rests flush with the distal femur. Attach the distal femoral cut block to the distal resection guide adaptor by sliding the magnetized distal block into the adjustable distal resection guide adaptor (Figure 7). Figure 7

Attach the adjustable distal guide adaptor and cut block to the adjustable femoral resection guide by sliding the two legs on the adaptor through the anterior holes of the resection guide. Continue sliding the adaptor until the block is sitting against the anterior cortex. Pin the resection block into place using 1/8” quick release drill pins in the most proximal pin holes of the block (Figure 8). To confirm the valgus angle, the alignment handle can be inserted into the adjustable distal resection guide adaptor and a ¼” alignment rod can be inserted and extended to the center of the femoral head (Figure 9). Remove the adjustable guide by disengaging the IM rod and pulling the guide and adaptor distally away from the distal resection block, leaving the distal resection block

WChoose the appropriate left or right symmetrical valgus wing and slide it onto the IM rod. Introduce the IM rod to the femoral canal to depressurize the canal. Slide the valgus wing until it rests against the distal femur (Figure 10). The “left” or “right” engraving on the block must face distally based on the leg being prepared. By rotating, align the lower edge of the valgus wing with equal amounts of posterior condyle extending underneath the bottom of the block. Slide the distal resection block and valgus block adaptor Figure 10

into the anterior holes of the valgus wing until the resection block contacts the anterior femur. Pin the resection block into place using 1/8” quick release drill pins in the most proximal pin holes of the block (Figure 11). To confirm the valgus angle, the alignment handle can be inserted into the valgus block adaptor and a ¼” alignment rod can be inserted and extended to the center of the femoral head (Figure 12). Remove the valgus wing by removing the IM rod and pulling the valgus wing and valgus block adaptor distally away from the distal resection block, leaving the distal resection block in place.

PREMIER™ TOTAL KNEE INSTRUMENTATION Distal Femoral Resection

DISTAL RESECTION Two resection slots of 0 or +3mm are available for the distal resection. The 0mm slot will resect 9mm from the most prominent part of the contacting distal condyle. If additional distal resection is required, the +3mm slot will resect 12mm. If additional distal resection is required beyond the +3mm slot, shift the resection guide proximal by utilizing the +2 or +4mm 1⁄8” pin holes. Use a .054” saw blade to complete the distal resection through the selected slot (Figure 13). Check the resected distal femur using a flat instrument. Recut or file as necessary to ensure proper resection. Note: Two distal femoral resection blocks can be used. One block utilizes the assistance of handles and the other relies on pins for fixation and stability (Figure 14). Figure 13

PREMIER™ TOTAL KNEE INSTRUMENTATION Femoral Sizing

€ FEMORAL SIZING Place the adjustable A/P Sizer flat against the resected distal surface with the feet in contact with posterior condyles of the femur.

FIXED ROTATION FEET, OPTION 1 Two options are available when utilizing posterior feet: 3 degree external rotation (left and right) and neutral (Figure 15).

ADJUSTABLE ROTATION FEET, OPTION 2 Figure 15

Adjustable dial feet can be used with the A/P Sizer. They are avaliable in left and right with the ability to set external rotation from 0 to 10 degrees. It is suggested that an initial setting of 3 degrees of external rotation be utilized (Figure 16). The femoral component size can now be read from the central scale. If the size indicated is in-between standard sizing or a larger flexion gap is desired, a choice may be made to choose the smaller size and shift the femoral 4-in1 block placement anteriorly. To shift the component anteriorly, turn the screw mechanism in the central portion of the sizer, which in turn raises the level of drill holes in 1mm increments (Figure 17).

Figure 16

Figure 17

A scale is located on the sizer to indicate how far the component will be anteriorly shifted.

PREMIER™ TOTAL KNEE INSTRUMENTATION Femoral Sizing

If M/L width is a concern, the appropriately sized M/L width checker can be inserted into the A/P Sizer to further evaluate the proper size of the femur (Figure 18). Drill the two 4-in-1 cutting block location holes utilizing the 1/8” drill pin (Figure 19). Note: The final M/L position of the component is not determined during this step, but is addressed later in the technique.

€ FEMORAL 4-IN-1 RESECTIONS Choose the slotted femoral A/P 4-in-1 block that matches the selected size on the A/P Sizer and place it into the 1/8” holes drilled into the distal femur. A .054” feeler blade can be used to determine the amount of anterior bone resection (Figure 20). If the feeler blade indicates a probability of notching, use the A/P femoral shift block to adjust the cut block holes anteriorly in 1mm increments (Figure 21). Moving the block anteriorly will resect additional posterior condylar bone.

Handles can be attached into the sides of the femoral 4-in1 block (Figure 22). Ensure the A/P block is sitting flush against the distal femur. If additional stability is required, 1/8” drill pins can be placed in the side holes provided. Once the block position is satisfactory, resect the anterior and posterior bone, and the anterior and posterior chamfers, with a .054” saw blade (Figure 23).

STANDARD PS BOX GUIDE, OPTION 1 Impact the size-specific box resection guide on the prepared distal femur (Figure 24). Secure the box resection guide with two 1/8” drill pins through the holes located in the anterior flange. Figure 24 Position the PS box chisel, with the beveled edge facing the distal femur, into the appropriate resection level; either bone conserving (BC), open box (OP), or closed box (CL) (Figure 25). Impact the PS box chisel to a depth approximately one-half CL

PS BOX PREPARATION WITH MILL, OPTION 2 Impact the size-specific box resection mill guide on the prepared distal femur. Secure the box resection guide with two 1/8” drill pins through the holes located in the anterior flange. Insert the appropriate size reamer into a power drill. Insert the tip of the reamer into the central hole in the posterior axle of the box resection guide (Figure 27). Under power, rotate the reamer around the axle anteriorly into the box guide. To guard against potential damage to Figure 27

the reamer tip, ensure the reamer is fully seated on the PS box mill pivot, maintain the reamer postion perpendicular to the axis of the pivot and avoid applying excessive force when milling. Use only as much force as necessary to aid the reamer’s advancement through the bone. Repeat this step with the reamer inserted in both the medial and lateral positions. If a bone conserving resection is desired, insert the appropriate magnet stop guide prior to reaming (Figure 28). Remove the box resection guide. Place the appropriate femoral box gauge into the resected intercondylar area to determine if appropriate depth and width of bone has been removed (Figure 29). Note: The closed box femur of the Vanguard® PS knee

Figure 28

requires the use of the CL resection level on the standard mill. The PS Box Mill removes sufficient bone for a closed box femoral component and can perform a BC resection by utilizing the appropriate size specific magnet stop.

PREMIER™ TOTAL KNEE INSTRUMENTATION Tibial Resection

INTRAMEDULLARY TIBIAL RESECTION, OPTION 2 Fully flex the knee and identify the center of the tibial plateau. Utilize a .375” IM drill to enter the tibial canal. The point of entry is just posterior to the anterior cruciate ligament insertion (Figure 36). Upon removal of the drill, slide the T-handle fluted rod through the body of the tibial resection guide with the tibial resection block in place and slowly introduce the IM rod to the tibial canal to depressurize the canal. To properly position the resection head, a silver button is located on the left side of the body of the guide. Press the button and slide the resection guide forward until the tibial Figure 36

cut block becomes flush with the anterior cortex of the tibia (Figure 37). The posterior slope of the resection is controlled by using a cutting head with the desired slope. Note: The standard Vanguard® CR tibial insert has a 3 degree posterior slope built into the articular surface. Place the stylus along the side of the resection guide on the perfered condyle. The tibial stylus reflects the total amount of bone to be resected.

Select a single peg or three peg trial patellar component that corresponds to the diameter and thickness and place it onto the patella. When the trial components are in place, check range-of-motion and stability of the knee (Figure 55). If tightness is found M/L, in flexion or in extension, appropriate soft tissue releases must be performed. Figure 54

Note: If trialing a PS knee, insert the appropriate PS trial post to the insert bearing. If additional constraint is needed, utilize the PS Plus trial post. Note: If distal femoral pegs are selected to be added to the femoral component, drill for pegs through the designated holes provided in the femoral trial (Figure 55).

32 Surgical Technique PREMIER™ TOTAL KNEE INSTRUMENTATION

PREMIER™ TOTAL KNEE INSTRUMENTATION Tibial Implant Insertion

€ TIBIAL IMPLANT INSERTION Assemble the modular tibial component, by choosing the appropriate stem (most primary cases will require a 40mm stem). The locking screw for the stem is included in the stem’s packaging. Place the stem taper on the bottom of the appropriate modular tibial baseplate. Be sure that the alignment keys match between stem and plate. Impact the tip of the stem once with a mallet to seat the stem taper. Note: The stem taper will hold the stem and plate together during insertion. The screw is tightened into the threads of the stem for added stem fixation. Plugs can be left in the screw holes of the baseplate if screw fixation is not used. Utilize the tibial impactor to firmly seat the component (Figure 56). Remove excess cement with a curette. Optional screw fixation: Using the drill guide and 1/8” drill, Figure 56

prepare a hole for screw acceptance. Note: The low-profile screws may be angled at 15 degrees in any direction to engage the best available cancellous and/or cortical bone. Frequent reference to the X-rays will guide the drilling and screw insertion sequence. With the baseplate firmly fixed, the provisional bearing may be reinserted, and a trial reduction performed to confirm joint tension and stability.

PREMIER™ TOTAL KNEE INSTRUMENTATION Femoral Implant Insertion

€ FEMORAL IMPLANT INSERTION Place the appropriate femoral component on the end of the femur and insert it manually as far as possible (until about 1cm of space remains between the component and the distal femur). Fully seat the component using the control femoral impactor (Figure 57). Remove the extruded cement with a curette. Running through a range-of-motion will help to pressurize the cement.

Figure 57

34 Surgical Technique PREMIER™ TOTAL KNEE INSTRUMENTATION

PREMIER™ TOTAL KNEE INSTRUMENTATION Patellar Implant Insertion

€ PATELLAR IMPLANT INSERTION Place the appropriate patellar component into the patella and push it into position with finger pressure so the peg(s) engage(s) the prepared hole(s). Position the patellar clamp onto the component and tighten the handle until the clamp head contacts the component. Clamp tightly to compress the implant (Figure 58). Remove extruded cement with a curette. The clamp should be left in position until the cement cures.

Figure 58

PREMIER™ TOTAL KNEE INSTRUMENTATION Surgical Technique 35

PREMIER™ TOTAL KNEE INSTRUMENTATION Locking Bar Insertion/Removal

€ LOCKING BAR INSERTION/REMOVAL Place the appropriate polyethylene bearing insert on the tibial baseplate and push posteriorly as far as possible using finger pressure. The polyethylene bearing must be flat on the baseplate in all directions. The locking bar, packaged with the tibial baseplate, is inserted into the medial side of the anterior tibial baseplate/polyethylene interface as far as possible using finger pressure (Figure 59). The locking bar must be tight upon insertion and should be too tight to insert completely with finger pressure only. Place the large curved end of the locking bar insertion forceps in the notch on the locking bar. The smaller square end should be placed in the notch of the anterior post of the tibial baseplate. Make sure the smaller square end Figure 59

catches on the post of the tibial tray and does not block the path of the locking bar. Squeezing the forceps will gradually push the locking bar until it clicks into place (Figure 60). A visual and audible confirmation should be made to ensure complete locking bar insertion.
