Learn the Stryker MAKO Express Workflow total hip replacement (using Accolade II and Tritanium implants) surgical technique with step by step instructions on OrthOracle. Our e-learning platform contains high resolution images and a certified CME of the Stryker MAKO Express Workflow total hip replacement (using Accolade II and Tritanium implants) surgical procedure.
The MAKO robot was first used in 2010 for a total hip replacement(THA). In 2015 FDA approval was granted and its use since then has increased dramatically. Whilst THA is a very successful operation, there continues to be an potentially reducible incidence of early failure from dislocation and malpositioning of components. The MAKO system has been designed by Stryker to increase the accuracy of component positioning, as well as sizing and it is hoped the longevity of lower limb joint replacement. Other systems are in their infancy at present and the Stryker MAKO is arguably the most common system currently used.
Stryker describe both an enhanced and express “workflow” for the MAKO total hip replacement. The express technique uses the MAKO technology to prepare the acetabular component and the enhanced technique assists with the femoral neck cut, broach version and combined component ante-version as well as acetabular preparation. The express workflow is a quicker surgical technique and focuses on accurate acetabular placement.
The MAKO technique requires a pre-operative CT scan of the patients pelvis and axial slices through the patients knee (to identify the epicondylar axis) and ankle. Using the information from this scan, exact sizing and positioning of the implants can be achieved. Intra-operatively a haptic arm from the MAKO robot is utilised to perform parts of the procedure such as acetabular reaming and cup placement. Intra-operatively the surgeon has real time feedback on the component position, leg length and hip offset.
If the surgeon is unhappy intra-operatively with any element of the MAKO plan (such as cup size, inclination, version), it can be immediately adjusted and the implantation executed to the new parameters. For instance if the planned cup anteversion doesn’t look correct in relation to the patient’s native transverse acetabular ligament, the version can be increased or decreased and the cup repositioned to suit the intra-operative findings.
It is vitally important that the position of the markers and arrays, which are applied to the operated limb and used for the robotic guidance, are not disturbed or adjusted during surgery as this will lead to inaccuracies unless re-calibration is performed.

- Each operation and the questions associated become a named course in the CPD section
- The operative technique itself is read as a lesson as is any company implant information if this is being assessed.
- You’ll need to tick the box to confirm this has been done and can do this immediately if you have already read the op tech.
- The vast majority of operations have a 10-15 MCQ quiz covering all aspects of the decision making and the technique
- There are four possible answers of which one is correct (or on occasion more correct) than the others.
- There are additional quiz modules on the surgical steps, the implants and problem cases being added continually
- The course is completed once all the lessons are read and quizzes submitted and passed.
- On successful completion of each quiz you will receive validated CPD points that add to the certificate in your CPD folder.
- Your dashboard also will contain a record of the time you have spent logged onto and using the site.
- The timer suspends after 5 minutes though if there is no activity.
- When you restart you will resume at the same point in the module.
- Once you have completed each quiz you will need to feedback on the module first then click “submit” and your paper will be marked.
The pass mark is 75%.
- If you fall below this level you will be directed back to re-read the slides where you’ve tripped up.
- Once these have been read you can re-do just the questions you failed on.
- Once you have passed the quiz you can return at a future stage & resit .
- Operation Quiz – 1 CPD point
- Surgical steps Quiz – 1/4 CPD point
- Implants Quiz – 1/4 CPD point
- Problem case Quiz – 1/2 CPD point
One CPD point equates to one hour of academic activity
Welcome to the Professional Development question section. The objective of taking these tests is to demonstrate that you have understood all aspects of the assessment and management of patients requiring surgical intevention. On successful completion you will receive a certificate accredited by both the Royal College of Surgeons of both England and Edinburgh as well as the British Orthopaedic Association.
