The Importance of Custom Rotational Alignment in Knee Replacement

The Importance of Custom Rotational Alignment in Knee Replacement

Understanding the Crucial Role of the MCL and Patella

 Knee replacement surgery has evolved significantly with the advent of custom rotational alignment techniques. Understanding and addressing the unique biomechanics of each patient's knee, particularly the medial collateral ligament (MCL) and patella, is critical for optimal results

Why Custom Rotational Alignment Matters

1. Personalised Approach for Better Outcomes: Custom rotational alignment in knee replacement, ensures that the prosthetic knee mirrors the patient's natural joint alignment. This bespoke approach is crucial for maintaining the knee's natural movement and stability.

2. Protecting the Medial Collateral Ligament (MCL): The MCL plays a vital role in stabilising the knee. Custom rotational alignment aids in reducing undue stress on the MCL, which is essential for preventing ligament overstrain and ensuring the longevity of the knee replacement.

3. Enhancing Patellar Tracking and Function: Proper alignment is critical for the patella, or kneecap, to glide smoothly over the knee. Misalignment can lead to patellofemoral pain and complications.

4. Reducing Wear and Extending Implant Life: Custom alignment, helps in evenly distributing the load across the knee joint, reducing wear on the implant and extending its lifespan.

The Process of Achieving Precision in TWIS-TKR

The journey to precise custom rotational alignment in TWIS-TKR involves advanced imaging techniques to map the patient's knee anatomy. This detailed analysis allows for a surgery plan that aligns the implant perfectly with the individual's knee mechanics, respecting the natural orientation of the MCL and patella.

TWIS-TKR: A Leap Forward in Knee Replacement

TWIS-TKR represents a significant advancement in knee replacement surgery, focusing on a patient-specific approach. This method not only alleviates pain but also aims to restore the knee's natural functionality and movement.


How does custom rotational alignment benefit the MCL?

By aligning the knee implant to the natural orientation of the MCL, custom rotational alignment reduces stress on the ligament, enhancing stability and reducing the risk of post-surgical complications.

Why is the patella's alignment important in knee replacement?

Correct alignment of the patella ensures smooth movement over the knee joint, reducing the risk of pain and dysfunction post-surgery.

What makes TWIS-TKR different from traditional knee replacements?

TWIS-TKR focuses on custom rotational alignment, tailored to each patient's unique knee anatomy, providing a more natural knee function and reducing the risk of complications.

Can TWIS-TKR prolong the life of a knee implant?

Yes, by ensuring proper load distribution across the knee joint, TWIS-TKR can reduce implant wear and extend its lifespan.

Is everyone a candidate for TWIS-TKR?

TWIS-TKR is suitable for many, but a detailed evaluation is necessary to determine if it's the best option for an individual's specific knee condition.
