1. INTRODUCTION

This brochure describes the Surgical Technique to implant a GMK Total Knee System using the 3D Printed Patient Specific MyKnee LBS instrumentation. MyKnee is a patient-specific cutting block which allows the surgeon to realise his pre-operative 3D planning, based on CT or MRI images of the patient’s knee. MyKnee LBS is a 3D Printed Patient-Specific cutting block which includes an integrated Ligament Balancing System. This surgical technique ensures soft tissue balancing both in extension and in flexion before performing any femoral resection.The bone resections are performed directly through the slots on the MyKnee cutting blocks, according to the surgeon’s preoperative planning.

1.1 INDICATIONS

MyKnee Cutting Blocks are intended to be used as anatomical cutting blocks specifically designed for a single patient to assist in the positioning of total knee replacement components intraoperatively and in guiding the marking of bone before cutting.

MyKnee Cutting Blocks are intended for use with GMK Total Knee System when the clinical evaluation complies with its cleared indications for use.

1.2 CONTRAINDICATIONS

Contraindications in using MyKnee instrumentation are the same as the situations when a total knee replacement is contraindicated. It is the surgeon’s responsibility to verify that the patient is not allergic to the material of which the MyKnee cutting blocks are made (Polyamide PA12).

1.3 PREOPERATIVE PLANNING

The pre-operative planning is managed through the website https://myknee.medacta.com in cooperation between the surgeon and Medacta International. Please contact Medacta International to gain access to the website.

The goal of the preoperative planning is to assess the surgical parameters regarding femoral and tibial implantation in order to manufacture dedicated single patient use cutting blocks. Parameters are to be planned by the surgeon and include:

• Femoral implant size

• Tibial implant size

• Femoral resections - Posterior cut height, on both condyles (medial and lateral)

- Distal cut height, on both condyles (medial and lateral)

• Femoral angles - Varus / valgus - Flexion / extension

• Femoral rotation - Internal / external rotation vs posterior condyles line and vs epicondylar axis

• Tibial resection - Proximal cut height related to both plateaux (medial and lateral)

• Tibial angles - Varus / valgus - Posterior slope.

CT or MRI imaging is used to create a tri-dimensional bone model of the patient’s knee anatomy. This bone replica is the model used to create the anatomical cutting blocks that can fit a patient’s knee morphology without using any alignment jigs to position them.

When using the MyKnee LBS distal cutting block, the surgeon will be able to modify the planned distal cut level before performing any femoral resection and taking into account the knee balancing. The MyKnee LBS distal cutting block also allows the femoral rotation, which has been preoperatively planned, to be modified. This modification can be done taking into account the soft tissue balancing.

NOTICE: Please refer to the official CT and MRI protocols available on the website https://myknee.medacta.com. Scanning taken with different protocols may lead to unusable images.

NOTICE: Before using MyKnee procedures, every Radiological Center must be registered. Please contact Medacta International to register your Radiological Center.

Page 5: Surgical Technique - Medacta · The 3D bone model can be supplied sterile or non-sterile. In case it is supplied non-sterile, it must be sterilized by the health care institution

CAUTION Different MyKnee cutting blocks are available depending on the scanning technology used. The surgeon will receive a MyKnee Surgical Planning Report (ref. M 08.59) that indicates the surgical parameters, according to his default profile previously set by the surgeon on the MyKnee website (see picture on the next page). It is the surgeon’s responsibility to validate the preliminary planning or set different parameters according to his own assessment. Both validation and changes in the planning must be communicated via the MyKnee website (see picture on the next page). After the planning is confirmed by the surgeon, MyKnee blocks are manufactured and delivered to the Hospital.

CAUTION MyKnee cutting blocks can be supplied sterile or non-sterile (see pictures below). In case they are supplied non-sterile, it is the health care institution’s responsibility to clean and sterilize them before use. Please read the “Note for sterilization” included at the end of this surgical technique.

1.

CAUTION A full conventional metallic instrument set must be available and ready for the operation with the MyKnee LBS.

NOTICE: With MyKnee LBS cutting blocks, the resections must be performed in the following order:

• Tibial resection

• Distal femoral resection

• A/P femoral resections and chamfers

CAUTION Federal law (USA) restricts this device to sale by or on the order of physician. Some specific instruments are fixed to the bone by means of dedicated pins. Before using the pins, ensure that they are intact and fully functional. BENT OR DEFECTIVE PINS CANNOT BE USED AND MUST BE REPLACED BY NEW ONES. When extracting pins it is important to avoid any bending. This results in axial alignment between the pin and the dedicated extractor. It is strongly recommended not to impact or hammer on any instruments unless otherwise specified in the surgical technique. For detailed instructions contact your local Medacta sales representative.

CAUTION This case is based on CT data: REMOVE FROM THE BONE THE CARTILAGE AND SOFT TISSUES COVERING THE CUTTING BLOCK CONTACT AREAS. All measurements shown are from the bone and do not include the thickness of the cartilage.

1.4 SURGICAL APPROACH

The most commonly used surgical approach is the medial parapatellar approach. Other approaches may be used depending on the surgeon’s practice.

CAUTION DO NOT remove any osteophytes from the tibia or from the femur, in order not to alter the bony references of the MyKnee anatomical cutting blocks.

CAUTION A lateral parapatellar approach may be indicated for some patients. Different MyKnee cutting blocks are available depending whether a medial or lateral surgical approach is used. The surgeon must indicate in the surgery planning which kind of surgical approach will be used.

2. TIBIAL RESECTION

2.1 TIBIAL CUTTING BLOCK POSITIONING

Each MyKnee tibial cutting block displays the following information:

• 1 - patient ID

• 2 - cutting block reference and lot number.

12

2.

Before starting the surgery, check the accuracy of the patient specific data.Example of patient ID: N_SUR_XTK_SN_DDMMYYYY

• N = first letter of patient’s given name

• SUR = first three letters of patient’s family name

• XTK (GMK Primary) = side operated, left (LTK) or right (RTK) XSK (GMK Sphere) = side operated, left (LSK) or right (RSK)

• SN = surgeon’s given and family name first letters

• DDMMYYYY = patient’s date of birth (DD=day, MM=month, YYYY=year).

NOTICE: If using a MyKnee MIS tibial cutting block, follow the same procedure as described in the “Tibial Resection” paragraph of the MyKnee MIS surgical tecnique.

CAUTION If the cutting block does not clearly indicate the patient identification string, it MUST NOT be used for the surgery. In such a case please contact Medacta staff immediately.

CAUTION DO NOT use MyKnee cutting blocks on a patient for whom the pre-operative planning has not been carried out. A MyKnee cutting block used on a different patient will lead to unpredictable total knee replacement outcomes.

CAUTION Do not remove any osteophytes from the tibial bone.

Before use, ensure that the MyKnee tibial cutting block is intact and in good working order, by visually inspecting the block. A 3D bone model of the patient’s femoral bone may be supplied with the MyKnee tibial cutting block. Matching the cutting block with the 3D bone model allows for an additional check of the cutting block integrity before use. The 3D bone model can be supplied sterile or non-sterile. In case it is supplied non-sterile, it must be sterilized by the health care institution (please read the “Note for sterilization” included at the end of this surgical technique).

The 3D tibial bone model allows to accurately simulate the correct positioning of the MyKnee tibial cutting block and to verify, by using the angel wing, the resection level, as the planned tibial resection level is marked on the bone model.

The block has to be positioned manually on the tibial plateaus.

3.

Page 9: Surgical Technique - Medacta · The 3D bone model can be supplied sterile or non-sterile. In case it is supplied non-sterile, it must be sterilized by the health care institution

Considering the anatomical shape of the block, only one orientation is possible. The correct placement corresponds to the maximum stability position of the block.

To ensure the maximum stability, verify that the points of contact between the MyKnee tibial cutting block and the tibial bone are respected. If bone models are available ensure that the contact points between MyKnee block and bone are in the position of the areas marked on the bone model.

4.

CT- and MRI-based cutting blocks contact area

5.

Lateral approach contact area Medial approach contact area

CAUTION Before positioning the MyKnee tibial cutting block, remove the soft tissues from the tibia without damaging the osteophytes.

CAUTION When using CT based MyKnee tibial cutting block, the cartilage and soft tissues covering the cutting block contact areas (see figures above) must be removed from the bone with the help of an electric cutter in order to obtain the most stable position of the cutting block. The cutting block contact areas can be easily identified on the bone model, if provided.

CAUTION An inaccurate positioning may lead to cutting parameters not in line with the planning.

Once the cutting guide has been properly arranged on the tibia, cut parameters are automatically set for the knee undergoing surgery according to the pre-operative planning (see § 1.3).

TIP The telescopic alignment rod can be connected to the cutting block (see red holes in the figure below) to help identify the correct position on the bone. A visual check on the cut level can be carried out using the angel wing (see yellow slot in the figure below). A visual check on the tibial slope can be carried out by inserting a pin in the guide without fixing it on the bone.

6.

Saw blade slot

Telescopic alignment rod holes

CAUTION Check the tibial varus/valgus with the telescopic alignment rod only after positioning the MyKnee cutting block (do not use the telescopic rod to position the MyKnee block).

TIP To enhance the intra-op evaluation of the planned tibial slope and implant position a pin can be inserted into the central hole of the tibial block. The trajectory passing through this pin, defines the A-P axis of the tibial base plate indicating its center. In addition, the pin is a helpful guide to check the planned tibial slope.

2.2 FIXING THE TIBIAL CUTTING BLOCK ON THE TIBIA

Once the tibial cutting block positioning is deemed satisfactory, it can be fixed on the tibia by use of standard 3.2 mm diameter pins as shown in the picture below.

NOTICE: To guarantee a stable fixation two parallel pins plus an oblique one must be used.

7.

Standard block parallel pins holes

Oblique pin holes

CAUTION Do not alter the cutting block position while drilling to create holes for pins in order to avoid any guide misalignment.

2.3 PERFORMING THE TIBIAL RESECTION

Once the tibial cutting block has been properly fixed to the tibia, visually double check the cut height by use of the standard angel wing before cutting. Thencarryoutthetibialresectionusingabladeupto1.27mm thick.

CAUTION Use physiological solution to cool the guide during the resection.

CAUTION After the resection, rinse the joint before positioning both the trial and final implant.

After the tibial cut has been done, remove the MyKnee cutting block from the tibia. Remove both oblique and parallel pins.

If a recut is necessary, position the corresponding conventional tibial cutting block on the parallel pins. The picture below shows the correspondence between MyKnee tibial cutting block pins holes and conventional tibial cutting block pins row.

3. DISTAL FEMORAL RESECTION

3.1 DISTAL CUTTING BLOCK POSITIONING

Each MyKnee distal cutting block displays the following information:

• 1 - patient ID

• 2 - cutting block reference and lot number.

1

9.

2

10.

Before starting the surgery, check the accuracy of the patient specific data. Example of patient ID: N_SUR_XTK_SN_DDMMYYYY

• N = first letter of patient’s given name

• SUR = first three letters of patient’s family name

• XTK (GMK Primary) = side operated, left (LTK) or right (RTK) XSK (GMK Sphere) = side operated, left (LSK) or right (RSK)

• SN = surgeon’s given and family name first letters

• DDMMYYYY = patient’s date of birth (DD=day, MM=month, YYYY=year).

CAUTION If the cutting block does not clearly indicate the patient identification string, it MUST NOT be used for the surgery. In such a case please contact Medacta staff immediately.

CAUTION DO NOT use MyKnee cutting blocks on a patient for whom the pre-operative planning has not been carried out. A MyKnee cutting block used on a different patient will lead to unpredictable total knee replacement outcomes.

CAUTION DO NOT remove any osteophytes from or around the trochlear groove before positioning the femoral cutting block on the bone.

The MyKnee LBS distal cutting block will be supplied pre-assembled. The surgeon should remove the MyKnee LBS rotating plate from the MyKnee LBS distal cutting block before positioning it. Starting from the first position shown in the figure below, turn the rotating plate by 90° and extract it from the MyKnee LBS distal cutting block (see step 1, 2 and 3 in the figure below).

Before use, ensure that the MyKnee femoral cutting block is intact and in good working order, by visually inspecting the block. A 3D bone model of the patient’s femoral bone may be supplied with the MyKnee femoral cutting block. Matching the cutting block with the 3D bone model allows for an additional check of the cutting block integrity before use. The 3D bone model can be supplied sterile or non-sterile. In case it is supplied non-sterile, it must be sterilized by the health care institution (please read the “Note for sterilization” included at the end of this surgical technique).

The 3D femoral bone model allows to accurately simulate the correct positioning of the MyKnee femoral cutting block and to verify, by using the angel wing, the resection level, as the planned femoral resection level is marked on the bone model.

Manually position the block on the distal femur. Only one orientation is possible due to the anatomical shape of the block, placing this correctly ensures the maximum stability of the block.

12.

13.

To ensure the maximum stability, verify that the points of contact between the MyKnee distal cutting block and the femur are respected. If bone models are available ensure that the contact points between MyKnee block and bone are in the position of the areas marked on the bone model. CT based and MRI based cutting blocks use different contact areas.

14.

CAUTION Before positioning the MyKnee LBS distal cutting block, remove the soft tissues from the femur without damaging the osteophytes.

CAUTION When using CT based MyKnee distal cutting block, the cartilage and soft tissues covering the cutting block contact areas (see figures above) must be removed from the bone with the help of an electric cutter in order to obtain the most stable position of the cutting block. The cutting block contact areas can be easily identified on the bone model, if provided.

CAUTION An inaccurate positioning may lead to cutting parameters not in line with the planning.

Once the cutting guide has been properly arranged on the femur, the cut parameters are automatically set for the knee undergoing surgery according to the pre-operative planning (see § 1.3).

TIP The telescopic alignment rod can be connected to the cutting block (see purple holes in the figure below) to help identify the correct position on the bone. A visual check on the distal cut level can be carried out using the angel wing. (see red slot in the figure below)

16.

Telescopic alignment rod holes

CAUTION Check the varus/valgus with the telescopic alignment rod only after positioning the MyKnee cutting block (do not use the telescopic rod to position the MyKnee block).

3.2 FIXING THE DISTAL CUTTING BLOCK ON THE FEMUR

Once the positioning is deemed satisfactory, the distal cutting block can be fixed on the femur as shown in the pictures below by use of standard 3.2 mm diameter pins.

NOTICE: To guarantee a stable fixation two parallel pins plus an oblique one must be used.

Two configurations are allowed, depending on the conventional instrumentation used:

• Standard instrumentation

• MIS instrumentation.

17.

Standard instrumentation:

Standard block parallel pins holes

Oblique pin hole

Saw blade slot

MIS instrumentation:

MIS block parallel pins holes

Oblique pin hole

MyKnee LBS Surgical Technique

14

To avoid A/P movement, the MyKnee LBS distal cutting block must also be fixed on the femoral distal condyles using the standard 3.2mm cortical pins (cortical pins ref. n. 02.07.10.2294,hudsonadapterref.n.02.07.10.4742).

18.

19.

3.3 EXTENSION BALANCING

Check the stability of the articulation by extending the leg (the tibia has been already resected) and put in contact the tibial cut and the MyKnee LBS distal cutting block as shown in figure below. Make sure that the cortical pins are fully inserted in the femur so that they cannot touch the tibial resection.

20.

21.

CAUTION Before performing the extension/flexion balancing, remove the osteophytes that could disturb this action.

Page 15: Surgical Technique - Medacta · The 3D bone model can be supplied sterile or non-sterile. In case it is supplied non-sterile, it must be sterilized by the health care institution

15

Minimum thickness in extension

22.

When implanting a Medacta implant, the MyKnee LBS distal cutting block will simulate the minimum thickness of the implant taking into account the sum between the thickness of the distal femur and the thickness of the tibia using the minimum polyethylene insert.

In case of laxity, a GMK spacer can be added on the distal side of the MyKnee LBS distal cutting block, simulating the thickness of the different PE inlays, until satisfactory stability is achieved.

3.4 FLEXION BALANCING

Remove the spacer that was added on the distal side of the MyKnee LBS distal cutting block. Insert the MyKnee LBS rotating plate into the MyKnee LBS distal cutting block. Starting from the first position, shown in figure 2 below, turn the rotating plate until the indicator and the values on the MyKnee LBS distal cutting block are in line.

1

2

325.

The value 0 corresponds to the external rotation which has been pre-selected by the surgeon during the preoperative planning (see § 1.3). Attach the spacer that was used during the extension balancing onto the GMK LBS rotational guide (Ref. n. 02.07.10.4107). Insert thestandardGMKLBS rotationalguide into the MyKnee LBS rotating plate and position it on the tibial cut. The rotating plate will turn and highlight the balancing value on the MyKnee LBS distal cutting block.

The MyKnee LBS rotating plate will indicate if it is necessary to modify the pre-selected external rotation according to the flexion balancing (values on the scale are expressed in degrees; +/- 6° is the maximum correction allowed). The anterior cut level can be checked using the angel wing inserted into the slots of the rotating plate.

26.

27.

CAUTION If necessary, perform a preliminary cut of the posterior condyle within the tightest compartment before inserting the GMK LBS rotational guide into the MyKnee LBS rotating plate.

Page 17: Surgical Technique - Medacta · The 3D bone model can be supplied sterile or non-sterile. In case it is supplied non-sterile, it must be sterilized by the health care institution

17

CAUTION When correcting a rotation of more than 3°, it is recommended to check that there is no «notching» with the anterior cortex before performing the anterior cut.

CAUTION It is advisable to compare the automatic adjustment of the rotation given by the rotating plate with the conventional anatomical references (Whiteside’s line and the epicondylar axis) or with the external rotation which has been pre-selected by the surgeon during the preoperative planning (value 0 on the rotating plate scale). Avoid any internal rotation and excessive external rotation. An excessive external rotation may be caused by inadequate medial ligament release.

CAUTION When implanting a GMK Sphere implant, avoid excessive external rotation. Refer to the GMK Sphere surgical technique for further details.

TIP The surgeon can decide to fix the external rotation selected in the pre-operative planning, (see § 1.3) by inserting a pin in the central hole.

28.

29.

NOTICE: Remember to assemble, on the GMK LBS rotational guide, the same spacer used during the evaluation of the extension gap (see § 3.3).

3.5 PREPARING THE 4IN1 CUTTING BLOCK FIXATION HOLES

After having selected the femoral external rotation and before removing the MyKnee LBS distal cutting block, prepare the holes for the 4-in-1 cutting block fixation using the dedicated drill.

30.

31.

CAUTION Do not alter the cutting block position while drilling to create holes for pins in order to avoid any guide misalignment.

3.6 PERFORMING THE DISTAL RESECTION

Remove the cortical pins from the bone. Visually double check the cut height prior to cutting, using the standard angel wing, then perform the distal resection using a blade upto1.27mmthick.

NOTICE: To guarantee stable fixation two parallel pins plus an oblique pin must be used.

CAUTION Use physiological solution to cool the guide during the resection.

CAUTION After the resection has been done, accurately rinse the joint before positioning both the trial and final implant.

After the distal resection has been done, remove the MyKnee cutting block from the femur. Remove both oblique and parallel pins. If a recut is necessary, position the corresponding conventional distal cutting block on the parallel pins. The picture below shows the correspondence between MyKnee distal cutting block pins rows and conventional distal cutting block pins holes.

CAUTION If the holes for the pins do not correspond to the ones on the conventional cutting blocks, a complete back up conventional instrument set must be available in the operative room to conclude surgery.

To perform a distal recut, follow the same procedure as described in the dedicated surgical technique of the Medacta knee implant.

TIP Taking into account the extension and flexion balancing, the surgeon can decide to modify the distal cut before performing any femoral resection. To modify the planned distal resection, remove the cortical pins and the MyKnee LBS distal cutting block from the bone. Position the conventional cutting blocks on the parallel pins and modify the distal resection level using the correction pin rows present on the conventional cutting blocks (each row will make a 2 mm correction).

19

4. ANTERIOR CUT, POSTERIOR CUT AND CHAMFERS

To perform the anterior, posterior and chamfer resections the conventional 4in1 cutting block of the planned femoral size is required.

After the MyKnee LBS distal cutting block has been removed from the femur position the anterior reference parallel pins in the corresponding holes (purple) using the dedicated pin impactor and slide the predetermined 4in1 cutting block on the femur. Be careful to slide the block on the corresponding zero reference line indicated on the 4in1 cutting block.

33.

Anterior reference parallel pins

CAUTION If the holes for the pins do not correspond to the ones on the conventional cutting blocks, a complete back up conventional instruments set must be available in the operative room to conclude surgery.
