The SL1 knee rehabilitation device is an innovative solution designed to accelerate recovery after knee joint surgeries including Total Knee Arthroplasty (TKA). This patented technology combines active and passive training methods to improve knee function and range of motion (ROM) during postoperative rehabilitation.

As an active training apparatus, the SL1 empowers patients to independently control their rehabilitation process. Users can adjust the training angle (0-38°), strength, and duration according to their individual recovery progress, pain tolerance, and mobility levels. This personalized approach ensures safe, pain-free training sessions that can be performed multiple times daily to accelerate the rehabilitation process.
The device features precise engineering with an aluminum alloy construction that provides durability while maintaining lightweight portability. The adjustable height (7-49cm) and lower limb stroke (0-65cm) accommodate various body types and rehabilitation stages. A professional medical ankle and foot fixation protector with double padding ensures both comfort and safety during use.

Clinical advantages include the combination of flexion and extension training which promotes knee joint stability. The clear scale and angle indicators allow both patients and therapists to accurately monitor progress. Unlike powered rehabilitation equipment, the SL1 requires no electricity, making it suitable for use in various settings including clinical environments and home use.
This rehabilitation tool is particularly effective for improving postoperative knee function. The coordinated training of upper and lower limbs enhances active movement ability, increases muscle strength, improves cardiopulmonary function, and promotes the recovery of proprioception. It's widely used in orthopedics, rehabilitation centers, geriatric departments, and traditional Chinese medicine practices.
