Zementfreie Schäfte The femoral and tibial components can also be stabilised into the bone by using non-cemented cylindrical stems, made of forged Ti6Al4V alloy.
Indications The principal preoperative planning factor is the correct diagnosis. It has to be determined whether the bone and stability situation allow the implantation of an uncoupled prosthesis. The main indications for implantation of TC-PLUS™ Revision are : • Degenerative or posttraumatic arthrosis •...
Contraindications Contraindications are : • Acute or chronic, local or systemic infections ( or in the case of a corresponding anamnesis ) • Severe muscle, nerve or vascular diseases that endangers the affected extremity • Laking bone substance or inadequate bone quality that endangers a stable seating of the prothesis •...
Case Study Preoperative situation Patient with varus displaced or implanted tibia, with a medial instability that must be revised because of pain and swelling.
Page 13
Postoperative Result Immediately postoperative; functional and pain-free reconstruction with TC-PLUS™ Revision knee.
Preoperative Planning A full-leg X-ray with the patient in the standing position is recommended for preoperative planning purposes. If this is not possible, an X-ray of the thigh, including the femoral head, should be taken. The X-ray images of the knee joint at three levels should be available for planning the surgery.
Page 15
Planning the surgery using the radiograph The following procedure is recommended for the anterior-posterior whole leg imaging process: 1. The femoral axis A (anatomical axis) is drawn onto the radiograph. 2. A line is drawn from the femoral head to the center of the knee (mechanical axis D) on the radiograph.
Surgical Technique Positioning of the patient for the surgery Surgery is performed whilst the patient is supine. It is recommended that the blood supply be partially blocked with the use of a tourniquet. But this is not absolutely necessary. The leg must be covered, so as to allow movement and secured to the operating table in such a way that the knee joint is brought into a stable 90°...

The femoral bushing is inserted into the femoral suspension device, so that depending on which side is the operation, the mark «L»...
Page 25
After preliminary drilling with the Ø 3.2 mm drill, the femoral / tibial revision cutting block is fixed with two bone pins ( 75 mm long ) through the holes marked «0». This position resects 9 mm from the distal femur, which corresponds to the distal thickness of the femoral prosthesis without femoral blocks.
Page 26
The distal resection is the reference for the following steps and has to be checked for accuracy. The femoral / tibial revision cutting block does not have to be removed yet because it will be used later (Depending the following chosen steps)! The side handles can be removed from the femoral / tibial revision cutting block and attached on the femoral A/P femoral cutting block revision.
Page 27
The rotation can be as well adjusted by applying anteriorly the femoral / tibial revision cutting block. After preliminary drilling with the Ø 3.2 mm drill, the A/P femoral cutting block revision is fixed with two bone oblique pins ( 38 mm with head ) through the lateral 45° oblique holes.
Page 28
The femoral chamfer resections are made through the corresponding slots ( slots with facet ). The A/P femoral cutting block revision is removed. Positioning the femoral reamer guide The chosen femoral reamer guide of the previously defined femoral size is positioned on the prepared bone and aligned intramedullary with the femoral valgus adapter ( «4°», «6°»...
Page 29
The posterior M/L dimension of the femoral reamer guide corresponds to the M/L implant dimension. The external contour of the femoral reamer guide corresponds to the anterior lateral femoral flange contour, the anterior laser markings to the anterior medial femoral flange contour. After preliminary drilling, the femoral reamer guide is fixed with bone pins ( 75 mm long or 38 mm with head ) through the anterior and lateral oblique holes.
Page 30
Removing the dorsal condyle residue Important: This must be checked in all cases! After having completed the femoral resections, use the curved osteotome to remove all osteophytes as well as protruding posterior condyles. At this point, a posterior contracture can also be released. This will improve flexion and prevent possible damage to the polyethylene insert by these bony projections.
Tibial Preparation The leg is flexed and any remaining osteophytes and the intercondylar eminence are removed. Tibial opening Open the tibial IM canal with the Ø 8 mm drill or directly with the Ø 8 / 14 mm stepped drill. Position the hole centrally M/L and one third from anterior.
Page 32
Preparing the tibial stem connection The stem connection recess is drilled with the Ø 10 / 20 mm stepped drill until the larger laser marking ( corresponding to the tibial resection with the smallest 9 mm tibial insert ). The engraved marking «Tibia»...
Page 33
Setting the resection height The tibial stylus is positioned on the tibial plateau. The tibial stylus can be used for both primary resections ( «11 mm» marking ) and for revisions resections ( «1 mm» marking ). Important In primary revision procedures, the «11 mm» tibial stylus is positioned on the lowest point of the less damaged condyle.
Page 34
After preliminary drilling with the Ø 3.2 mm drill, the femoral / tibial revision cutting block is fixed with two bone pins ( 75 mm or 100 mm long ) through the holes marked «0». Handles can be attached. The lock lever is set to «OPEN» and the tibial resection guide IM is removed from the femoral / tibial revision cutting block by unscrewing the top small grub screw.
Page 35
As guidance for the vertical tibial augmentation block cut, two bone pins (length 75 mm or 100 mm are inserted into the two proximal holes level with closed saw slot. The vertical cut is performed between the two pins to the depth of the augmentation block.
Page 36
Tibial size determination The chosen trial stem is attached to the extension for trial stem ( Ø 8 mm ) and with the modular handle carefully inserted into the tibial IM canal so the line marked with «MIN.» is approximately level to the distal bone resection. The modular handle is now removed.
Page 37
Then the tibia slope adapter «3°», the alignment bushing «8», the extension of the trial stem ( Ø 8 mm ) and the trial stem itself are removed. The tibial sizer is additionally fixed with two or four bone pins with heads (25 mm or 38 mm). The corresponding manipulation tibial insert, which had previously been defined with the joint gap spacer, is placed on the tibial sizer.
Page 38
Preparing the tibial medullary cavity The tibia rasp guide is positioned on the tibial sizer and fixed with the retaining screw. The proximal tibia marrow space is definitively prepared with the tibia rasp. The tibia rasp is tapped in to the stop. Important The small tibia rasp guide and tibia rasp are used for tibia sizes 2 and 4 («2, 4») , and the large for tibia sizes...
Offset Stem Option Preparing the tibial anchorage for offset stems. Positioning the tibial sizer for offset stems When using tibia blocks, appropriate manipulation tibia blocks («5 mm», «10 mm» and «15 mm») are available. They are fixed laterally on the manipulation tibial component ( tibial sizer ).
Page 40
Fixing the stem transfer guide After insertion of the vertical bone pins with head, the transfer guide can be placed in the tibial component. The transfer guide takes the offset position by clamping the lever and acts as a guide for assembly of the manipulation prosthesis and later for assembly of the implant.
Page 41
Preparing the tibial trial The corresponding tibial sizer with the matching tibial anchorage connection and «OFFSET» stem holder are mounted as the manipulation tibial component. Important Assembly is carried out on the instrument table. The transfer guide (3.75 mm) is positioned based on the fins.
Page 42
Trial reduction ( femoral component ) The manipulation femoral component is screwed to the manipulation femoral adapter (corresponding to the preset valgus angle) and the trial stem (corresponding to the last reamer). Important There is a danger that the same trial stem will be needed on the femur and on the tibia.
Posterior-Stabilized Option In the case of complete insufficiency of the posterior cruciate ligament or if it is cut during surgery, e.g. with bending contractures greater than 30°, dorsal instability in bending position is possible. A posterior-stabilized model (PS) for cemented application is available as compensation. It includes a revision femoral component which includes a box in the intercondylar region designed to accept a PS tibial insert with a higher pin.
Page 44
The box is prepared medially and laterally with the oscillating saw. Important The medial and lateral saw cuts are aligned at an inclination to make it easy to place the IM-guided femoral component (valgus) in the correct position. Preparing the femoral box According to the predetermined valgus angle, the corresponding femoral valgus adapter ( «4°», «6°»...

If the posterior surface of the patella is not replaced, the patella is freed osteophytes and denerved. Positioning the patella clamp and patella resection The patellar instruments permit the use of the «...
Page 47
Milling Mount the patellar bushing onto the patellar clamp with the ratchet. Select the patellar reamer to match the corresponding patella size. Depending on the selected anchoraging technique, mill briefly ( « onlay » technique ) or countersink by 3 mm to 5 mm ( « inlay » technique ). Milling down to the stop results in a depth of 5 mm.
Assembling the Implants - Components The assembling block is essential for safe and gentle assembling of the implants. Important When assembling the implant component, always start with the stem first. Then the blocks can be fixed. Otherwise the block screw may come loose during impacting. Be aware;...
Page 49
Assembling by using offset stems The offset stem ( page 65 ) is inserted into the taper on the assembling block and set to the offset position with the aid of the transfer guide ( pre-assembled with the centering rings and straight surface on the elbow on the stem must be flush with the straight internal surface of the transfer guide ).
Page 50
Assembling the tibial blocks There are blocks with a thickness of 5 mm, 10 mm and 15 mm available for the tibial component ( page 63 ). To enable tibial block assembly the required PE pegs must first be removed. Important The tibial blocks can be inserted either medially or laterally ( excepted tibial blocks size 15 mm ).
Page 51
Fixing the stem ( cemented / non-cemented ) to the femoral component The stem ( page 64 and 65 ) is inserted into the taper. Important Pay attention that the tapered connection is undamaged, clean and dry before mounting and by using non- cemented stems that a pocket is anterior, not a rib.
Page 52
Securing the stem The stem is additionally secured with the stem retaining screw. The retaining screw must be tightened with the screwdriver with torque. The required torque is reached when the line reaches the Stem/Block position ( 4.5 Nm ). Important The stem retaining screw for retaining the stem is packaged with the femoral component.
Implanting the Components Mix the bone cement according to the respective manufacturer's instructions. Clean, wash and dry the bone bed sufficiently. Modern cementing techniques using a vacuum mixer and jet lavage are recommended. The TC-PLUS™ Revision knee is used with cement, with the exception of non- cemented stems.
Page 54
Last controlling Prior to definitive assembly of the tibial insert it is possible to use the tibial insert trial for a final trial reduction. Before the cement has set, the excess cement must be removed in extension. Insertion of the tibial insert The ultracongruent tibial insert ( or PS tibial insert ) is slid onto the tibial component and positioned bent at 90°.
Page 55
After manual placement of the PE retaining screw into the tibial insert, the PE retaining screw is tightened with the screwdriver with torque. The required torque is reached when the line reaches the PE position ( 2.5 Nm ). Important The screwdriver with torque is maintenance-free.
Wound closure The wound must again be rinsed out thoroughly after implantation. Close the wound in layers, inserting two intra-articular and one subcutaneous Redon drain. Postoperative Treatment Rehabilitation The operated leg is immobilized in a splint and the knee joint is cooled. Isometric contraction exercises should be performed on the first postoperative day.
Sterilization Implants All the implants described in this Surgical Technique are sterile when they are delivered Resterilization is not allowed. by the manufacturer. Instruments System components and instruments are not sterile when they are delivered. Before use they must be cleaned by the usual methods in accordance with internal hospital regulations and sterilized in an autoclave in accordance with the legal regulations and guidelines applicable in the relevant country.
