TWIS TKR - Turn With Intelligent Stability Total Knee Replacement: Advanced Kinematic Intelligence  for Enhanced Joint Function

TWIS-TKR: Revolutionizing Knee Replacement Surgery

The Turn With Intelligent Stability Total Knee Replacement, known as TWIS-TKR, represents a groundbreaking approach in total knee replacement. This innovative technique focuses on custom kinematic rotation alignment, offering patients a more natural and responsive knee joint. Key aspects of TWIS-TKR, based on current understanding and research, are as follows:

Surgical Approach:

  • TWIS-TKR employs a sophisticated alignment technique that accounts for the natural turning movements of the knee, ensuring optimal rotational alignment.
  • The approach prioritises intelligent stability, using advanced technologies to provide a dynamically stable joint that adapts to different movement patterns and loads.

Customization and Flexibility:

  • This technique allows for unparalleled customisation in knee replacement surgery, offering flexibility in 3D space and adapting to all planes of movement.
  • The intelligent design of TWIS-TKR accommodates individual patient anatomy and kinematics, resulting in a truly personalised joint replacement experience.


  • Enhanced Mobility: Patients experience a greater range of motion and more natural knee function post-surgery.
  • Increased Stability: Intelligent stability features ensure the knee remains stable through various activities, reducing the risk of complications.
  • Faster Recovery: The custom fit and advanced design of TWIS-TKR can lead to quicker rehabilitation and return to daily activities.


The effectiveness of Turn With Intelligent Stability Total Knee Replacement (TWIS-TKR) is supported by a growing body of clinical evidence. This evidence underscores the superiority of TWIS-TKR over traditional knee replacement methods, both in terms of surgical outcomes and patient satisfaction. Key findings from studies and clinical trials are outlined below:

Improved Functional Outcomes

  • Clinical studies focusing on TWIS-TKR have reported significantly better functional outcomes. This includes improved range of motion, enhanced joint stability, and a more natural knee movement, closely mimicking the kinematics of a healthy knee.
  • Research indicates that patients with TWIS-TKR demonstrate quicker return to normal activities, including walking and climbing stairs, due to the intelligent design that accommodates natural knee mechanics.

Enhanced Patient Satisfaction with TWISTKR

  • Patient-reported outcome measures (PROMs) in studies reveal higher satisfaction levels among TWIS-TKR recipients. This satisfaction is attributed to the natural feel and functionality of the replaced knee, offering a quality of life comparable to pre-degeneration conditions.
  • Surveys indicate that patients experience less pain and discomfort post-surgery, contributing to overall enhanced satisfaction with the TWIS-TKR procedure.

Reduced Complication Rates:

  • Comparative studies between TWIS-TKR and conventional knee replacements have shown a decrease in complication rates. The intelligent stability of TWIS-TKR contributes to fewer incidents of post-operative dislocations and less wear and tear on the prosthetic components.
  • Longitudinal studies suggest a lower rate of revision surgeries in patients who underwent TWIS-TKR, highlighting its durability and long-term effectiveness.

Accelerated Recovery Times:

  • Due to the customised fitting and alignment provided by TWIS-TKR, patients often experience faster recovery periods. The intelligent design reduces tissue trauma during surgery, leading to less postoperative pain and quicker rehabilitation.
  • Clinical trials have documented shorter hospital stays and a reduced need for post-operative pain management in TWIS-TKR patients, underscoring the procedure's efficiency and patient-friendly approach.

Biomechanical Advantages with TWIS-TKR

  • Biomechanical analyses in several studies have validated the design principles of TWIS-TKR. The alignment and stability features are shown to optimally distribute load across the knee joint, reducing stress on both the implant and the surrounding tissues.
  • Simulated wear testing and computational modelling in research settings have predicted a longer lifespan for TWIS-TKR implants, suggesting a sustainable solution for knee replacement needs.

Integration with Artificial Intelligence from MAI-Motion:

  • TWIS-TKR utilises state-of-the-art artificial intelligence from MAI-Motion, offering a groundbreaking approach to knee replacement surgery. This integration allows for precision in surgical planning and execution, tailoring the procedure to each patient's unique anatomical and functional needs.
  • The AI system assists in analyzing patient-specific data, helping surgeons in decision-making to achieve optimal alignment and stability. This level of customisation ensures that each TWIS-TKR procedure is uniquely suited to the patient's knee mechanics.

Unique Enhanced Recovery Pathway:

  • A standout feature of TWIS-TKR is its unique enhanced recovery pathway. This patient-centric approach significantly reduces recovery time and improves overall rehabilitation outcomes.
  • The pathway is designed to minimise hospital stay, enhance mobility, and expedite the return to daily activities, thereby improving the quality of life for patients post-surgery.

TWISTKR pathway

Proprietary Pain Relief Protocol:

  • TWIS-TKR incorporates a proprietary pain relief protocol, tailored to reduce post-operative discomfort and accelerate recovery. This protocol is a key differentiator, offering patients a more comfortable and manageable postoperative experience.
  • The pain management strategy is comprehensive, combining medication, therapy, and patient education to effectively manage pain and facilitate a smoother recovery process.

Conclusion on TWIS-TKR:

TWIS-TKR is more than just a surgical technique; it represents a holistic approach to knee replacement. By integrating AI-driven precision, a unique recovery pathway, and an innovative pain relief protocol, TWIS-TKR sets a new standard in patient care and outcomes in knee arthroplasty. These advanced features make TWIS-TKR a leading choice for surgeons and patients alike, promising improved functionality, faster recovery, and enhanced patient satisfaction.
