The Active-K represents a significant leap forward in mechanotherapy, offering a versatile solution for mobilizing knee and hip joints. Engineered for both clinical precision and patient comfort, this device ensures that every movement is anatomically correct, fostering a safe and effective recovery environment. Its lightweight yet robust design allows medical professionals to bring advanced therapy directly to the patient, securing easily to treatment tables or beds with integrated stabilization supports.

Beyond simple mobilization, the Active-K empowers patients with real-time feedback. The advanced, interactive hand controller features a full-color LED screen and an intuitive icon-based menu, making it easy to navigate through therapy sessions. With the integral footplate sensor, exercise forces are measured accurately, allowing for computer-controlled coordination therapies that adapt to the patient's specific needs. This intelligent system creates a transparent recovery process where progress is tracked and stored via the Patient Chip Card.

Key Features and Benefits

Precision Engineering: Built to withstand +/- 30 kg of force while maintaining a lightweight profile (17 kg) for easy portability within the clinic.
Anatomical Accuracy: Designed to strictly maintain anatomically correct movements, reducing the risk of joint strain during therapy.
Versatile Stabilization: Features fold-out stabilization supports and optional straps to securely attach to any treatment table or bed.
Intelligent Feedback: An integral footplate sensor measures exercise forces, while the interactive hand controller provides instant visual feedback on the full-color LED screen.
Customizable Therapy: Includes a computer-controlled motor for CAM and coordination therapies, along with pre-programmed protocols for specific clinical indications.
Patient-Centric Design: Fully adjustable to suit different heights and sizes, supporting a maximum patient weight of 275 kg.
Data Management: Comes with a Patient Chip Card for easy storage and retrieval of individual therapy data.
Reliability: Backed by a 2-year warranty for long-term peace of mind.

Indications for Use

The Active-K is specifically indicated for patients recovering from extensive joint surgery who require early mobilization and progressive strengthening. It is suitable for:

Post-operative rehabilitation of the knee and hip.
Total knee or hip replacement recovery.
Ligament reconstruction (ACL/PCL).
Articular cartilage repair procedures.
Restoration of proprioception and coordination after traumatic joint injury.
Return to sport after joint surgery.
Customizable resistance levels for progressive strengthening.
Adjustable straps for a secure fit on any leg size.
Durable materials for long-term use.
Lightweight and portable design for easy transport and use at home or in clinical settings.
Non-slip foot pedals for added safety during exercise.
Reduced risk of post-operative complications such as blood clots or muscle atrophy.
Improved range of motion and joint stability.
Increased muscle strength, endurance, and coordination.
Quicker return to daily activities and sports.
Personalized resistance settings for targeted rehabilitation.
Can be used for a variety of injuries and conditions, including ACL tears, knee replacements, and patellar tendonitis.

Patient Comfort and Safety

Recovery requires an environment where the patient feels secure. The Active-K prioritizes safety through precise, electronically controlled movements that never exceed the clinician's programmed limits. The anatomical design ensures the limb is properly aligned throughout the extension and flexion cycles, minimizing discomfort. By allowing the patient to engage in Controlled Active Motion, the device provides bio-feedback, giving the patient a sense of control over their rehabilitation and reducing the anxiety often associated with post-surgical movement.

Accelerated Healing: Stimulates joint metabolism and promotes the regeneration of cartilage and damaged ligaments.
Fluid Management: Assists in faster hematoma reabsorption and improves both blood and lymph circulation, serving as a prophylaxis for thrombus and embolism syndromes.
Stiffness Prevention: Continuous movement prevents the formation of adhesions and joint stiffness common after surgery.
Seamless Progression: Effectively bridges the gap from passive motion to active training, introducing resistive therapy exactly when the patient is ready.
Sensory Restoration: Expedites the return of coordination and sensory perception following joint surgery.
Versatile Muscle Training: Supports multiple exercise protocols including concentric, eccentric, isokinetic, and isometric contractions.
