Older models in good working condition may be on the lower end, while fully equipped units with minimal wear could command higher prices. It’s important to factor in the costs of calibration and potential repairs, as sourcing parts for a discontinued model may increase long-term ownership costs.
Given the technological advancements of newer devices like the DYNEELAX® and GNRB®, which offer greater precision and reproducibility, investing in a KT-2000 may only be suitable for those specifically seeking this legacy tool. However, for most clinics, upgrading to a more advanced robotic arthrometer may be a better long-term investment for ensuring accuracy and supporting modern ACL diagnostics and rehabilitation techniques.
II. 2024 Alternative: Robotic Arthrometers - The Future of ACL Injury Treatment
Since the KT-2000’s discontinuation, significant advancements in orthopedic testing devices have emerged. Robotic arthrometers like DYNEELAX® and GNRB® provide a more advanced and reliable way of assessing ACL laxity. These devices don’t just measure displacement but analyze a full compliance curve of the ACL, offering deeper insights into the ligament’s health and its ability to withstand varying forces.
Key Differences from the KT-2000:
- Dynamic Compliance Curves: Rather than focusing on a single point of displacement, these arthrometers provide a dynamic analysis of how the ACL responds under different forces.
- Precision and Reproducibility: Robotic systems eliminate human error, ensuring consistent and reproducible results that are vital for both diagnosis and rehabilitation.
- Comprehensive Knee Evaluation: In addition to translation, devices like Dyneelax also measure rotation, making it the only device worldwide capable of assessing both movements. This offers a more complete understanding of knee stability.
- Digital Database: All Results are stored in a database which makes it easy to share among hospital departments.
- Safety of use in Post-op: Robotic systems enables precise force application. This is vital in post-op during ACL rehabilition. KT-2000 being manual tools, it is not possible to test the graft 1 month post-op.
III. A New Paradigm in Knee Ligament Treatment
By choosing robotic arthrometers like DYNEELAX® and GNRB®, clinicians are embracing the latest in arthrometer technology. These devices enhance the treatment of ACL injuries from diagnosis through full recovery.
3.1 Diagnosis of ACL Injuries
Robotic arthrometers like GNRB® offer significant advantages in diagnosing ACL injuries, particularly partial ACL ruptures, which are often missed by traditional methods like MRI.
A 2023 study by Cojean et al. (2023) highlighted this, showing that arthrometers are superior in detecting partial ruptures. GNRB® measures the anterior tibial translation in precise increments, providing real-time feedback on how the ligament responds under force. This objective data is invaluable for making accurate diagnoses early on, which is essential for successful treatment.
3.2 Surgical Planning
Beyond diagnosis, DYNEELAX® plays a critical role in surgical planning. A 2024 study by Guegan et al. (2024) demonstrated that Dyneelax’s ability to measure both translation and rotation helps evaluate the peripheral structures of the knee, such as the posterolateral corner and other supporting ligaments.
This rotational data is crucial when deciding whether additional procedures, like Lateral Extra-Articular Tenodesis (LET), are necessary to restore knee stability. This level of analysis allows surgeons to tailor the procedure to each patient’s unique anatomy, optimizing outcomes and reducing the risk of re-injury.
3.3 Post-Surgery Rehabilitation
One of the most significant advancements with robotic arthrometers is their role in rehabilitation. Following ACL reconstruction surgery, determining when a patient is ready to return to sports or physical activity is critical. Premature return can lead to re-injury, while delaying recovery too long can weaken the joint.
The DYNEELAX® excels in this area. According to Forelli‘s 2023 study, Dyneelax is used to monitor the condition of the ACL graft throughout rehabilitation. By tracking both translation and rotation, it offers a personalized rehabilitation plan based on the patient’s specific recovery progress. This approach ensures that each patient can return to activity when their knee has fully healed, significantly reducing the risk of complications.
IV. The Importance of Reproducibility in ACL Treatment
One of the KT-2000’s limitations was its reliance on the examiner’s skill to achieve accurate results. This human factor often led to inconsistencies in measurements, making it difficult to track a patient’s progress accurately over time.
